# Item 1. BUSINESS

# OVERVIEW

The CurrencySharesSM
Mexican Peso Trust (the Trust) is a grantor trust that was formed on June 8,
2006. The Trust issues shares (the Shares) in blocks of 50,000 (a
Basket) in exchange for deposits of Mexican Pesos and distributes Mexican
Pesos in connection with the redemption of Baskets. The Shares trade on NYSE Arca under
the ticker symbol FXM.

The investment objective of the Trust
is for the Shares to reflect the price of Mexican Peso plus accrued interest, less the
expenses of the Trusts operations. The Shares are intended to offer investors an
opportunity to participate in the market for the Mexican Peso through an investment in
securities. The Shares are intended to provide institutional and retail investors with a
simple, cost-effective means of gaining investment benefits similar to those of holding
the Mexican Peso. The Shares are bought and sold on NYSE Arca like any other
exchange-listed security. The Shares are backed by the assets of the Trust, which does not
hold or use derivative products. The value of the holdings of the Trust is reported on the
Trusts website, www.currencyshares.com, every business day.

# THE TRUST

General

The Trust holds Mexican Pesos and,
from time to time, issues Baskets in exchange for deposits of Mexican Pesos and
distributes Mexican Pesos in connection with redemptions of Baskets. The Mexican Pesos
held by the Trust will be sold only (1) if needed to pay Trust expenses, (2) in the event
the Trust terminates and liquidates its assets or (3) as otherwise required by law or
regulation.

The
Sponsor

The Sponsor of the Trust generally
oversees the performance of the Trustee and the Trusts principal service providers,
but does not exercise day-to-day oversight over the Trustee or the Trusts service
providers. The Sponsor is Rydex Specialized Products LLC, a Delaware limited liability
company.

The Trusts only ordinary
recurring expense is expected to be the Sponsors fee. The Sponsor is responsible for
payment of the following administrative and marketing expenses of the Trust: the
Trustees monthly fee, typical maintenance and transaction fees of the Depository,
NYSE listing fees, NYSE Arca listing fees, printing and mailing costs, audit fees and
expenses, up to $100,000 per annum in legal fees and expenses, and applicable license
fees. The Sponsor also paid the costs of the Trusts organization and the costs of
the initial sale of the Shares, including the applicable SEC registration fees. The
Sponsors fee accrues daily at an annual nominal rate of 0.40% of the Mexican Peso in
the Trust. The Sponsor was paid $62,843 for the period covered by this report.

The
Trustee

The Bank of New York, a banking
corporation with trust powers organized under the laws of the State of New York, serves as
the Trustee. The Trustee is responsible for the day-to-day administration of the Trust,
including keeping the Trusts operational records.

Net
Asset Value

The Trustee calculates, and the
Sponsor publishes, the Trusts Net Asset Value (NAV) each business day.
To calculate the NAV, the Trustee adds to the amount of Mexican Pesos in the Trust at the
end of the preceding day accrued but unpaid interest, Mexican Pesos receivable under
pending purchase orders and the value of other Trust assets, and subtracts the accrued but
unpaid Sponsors fee, Mexican Pesos payable under pending redemption orders and other
Trust expenses and liabilities, if any. The NAV is expressed in U.S. Dollars
(USD) based on the Noon Buying Rate, which is the USD/Mexican Peso
exchange rate as determined by the Federal Reserve Bank of New York as of 12:00 PM. (New
York time) on each day that NYSE Arca is open for regular trading. If, on a particular
evaluation day, the Noon Buying Rate has not been determined and announced by 2:00 PM (New
York time), then the most recent Noon Buying Rate is used to determine the NAV of the
Trust unless the Trustee, in consultation with the Sponsor, determines that such price is
inappropriate to use as the basis for such valuation.

1

---

The Trustee also determines the NAV
per Share, which equals the NAV of the Trust divided by the number of outstanding Shares.
The NAV of the Trust and NAV per Share is published by the Sponsor on each day that NYSE
Arca is open for regular trading and is posted on the Trusts website,
www.currencyshares.com.

Depository
and Deposit Accounts

JPMorgan Chase Bank, N.A., London
Branch is the Depository. The Depository maintains two deposit accounts for the Trust, a
primary deposit account which earns interest and a secondary deposit account which does
not earn interest (collectively, the Deposit Accounts). Interest on the
primary deposit account accrues daily and is paid monthly. If the Sponsor believes that
the interest rate paid by the Depository is not competitive, the Sponsors recourse
is to remove the Depository by terminating the Deposit Account Agreement and closing the
accounts. The Depository is not paid a fee for its services to the Trust. The Depository
may earn a spread or margin over the rate of interest it pays to
the Trust on the Mexican Peso deposit balances. The secondary deposit account is used only
in connection with mid-month creations and redemptions of Baskets, to account for interest
that has been earned on the primary deposit account during the month but not yet paid, and
to receive interest earned on the primary deposit account, pay Trust expenses and
distribute any excess interest to Shareholders on a monthly basis.

The secondary deposit account is used
to account for interest received and paid out on creations and redemptions of Baskets. The
secondary deposit account is also used to account for interest earned on the primary
deposit account, pay Trust expenses and distribute any excess interest to Shareholders on
a monthly basis. In the event that the interest deposited exceeds the sum of the
Sponsors fee for the prior month plus other Trust expenses, if any, then the Trustee
will direct that the excess be converted into USD at a prevailing market rate and the
Trustee will distribute the USD as promptly as practicable to Shareholders on a pro rata
basis (in accordance with the number of Shares that they own).

Trust
Expenses

In certain exceptional cases the
Trust may pay expenses in addition to the Sponsors fee. These exceptions include
expenses not assumed by the Sponsor, taxes and governmental charges, expenses and costs of
any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust
or action taken by the Trustee or the Sponsor to protect the Trust or the interests of
Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, and
legal expenses in excess of $100,000 per year.

Termination

The Trust will terminate upon the
occurrence of any of the termination events listed in the Depositary Trust Agreement and
will otherwise terminate onJune 8, 2046.

THE SHARES

General

Each Share represents a proportional
interest, based on the total number of Shares outstanding, in the Mexican Pesos owned by
the Trust, plus accrued and unpaid interest less accrued but unpaid expenses (both
asset-based and non-asset based) of the Trust. All Shares are of the same class with equal
rights and privileges. Each Share is transferable, fully paid and non-assessable.

Limited
Rights

The Shares are not a traditional
investment. They are dissimilar from the shares of a corporation operating a
business enterprise, with management and a board of directors. Trust Shareholders do not
have rights normally associated with owning shares of a business corporation, including,
for example, the right to bring oppression or derivative actions.
Shareholders have only those rights explicitly set forth in the Depositary Trust
Agreement. The Shares do not entitle their holders to any conversion or pre-emptive rights
or, except as provided herein, any redemption or distribution rights.

2

---

Voting
and Approvals

Shareholders have no voting rights
under the Depositary Trust Agreement, except in limited circumstances. If the holders of
at least 25% of the Shares outstanding determine that the Trustee is in material breach of
its obligations under the Depositary Trust Agreement, they may provide written notice to
the Trustee (or require the Sponsor to do so) specifying the default and requiring the
Trustee to cure such default. If the Trustee fails to cure such breach within 30 days
after receipt of the notice, the Sponsor may remove the Trustee. The holders of at least
66 2/3% of the Shares outstanding may vote to remove the Trustee. The Trustee must
terminate the Trust at the request of the holders of at least 75% of the outstanding
Shares.

Creation
and Redemption of Shares

The creation and redemption of
Baskets requires the delivery to the Trust or the distribution by the Trust of the amount
of Mexican Pesos represented by the Baskets being created or redeemed. This amount is
based on the combined NAV per Share of the number of Shares included in the Baskets being
created or redeemed, determined on the day the order to create or redeem Baskets is
accepted by the Trustee.

Only Authorized Participants may
place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust
Company participant that is a registered broker-dealer or other securities market
participant, such as a bank or other financial institution that is not required to
register as a broker-dealer to engage in securities transactions and has entered into a
Participant Agreement with the Trustee.

Before initiating a creation or
redemption order, an Authorized Participant must have entered into a Participant Agreement
with the Sponsor and the Trustee. The Participant Agreement provides the procedures for
the creation and redemption of Baskets and for the delivery of Mexican Pesos required for
creations and redemptions. The Participant Agreements may be amended by the Trustee and
the Sponsor. Authorized Participants pay a transaction fee of $500 to the Trustee for each
order that they place to create or redeem one or more Baskets. Authorized Participants who
make deposits with the Trust in exchange for Baskets receive no fees, commissions or other
form of compensation or inducement of any kind from either the Sponsor or the Trust. No
Authorized Participant has any obligation or responsibility to the Sponsor or the Trust to
effect any sale or resale of Shares.

# Item 1A. RISK FACTORS

You should consider carefully the
risks described below before making an investment decision. You should also refer to the
other information included in this report, including the Trusts financial statements
and the related notes.

The value of the Shares relates
directly to the value of the Mexican Pesos held by the Trust. Fluctuations in the price of
the Mexican Peso could materially and adversely affect the value of the Shares.

The Shares are designed to reflect
the price of the Mexican Peso, plus accumulated interest, less the Trusts expenses.
The price of the Mexican Peso has fluctuated widely over the past several years. Several
factors may affect the price of the Mexican Peso, including:

| | Debt
level and trade deficit of Mexico;
|- | ---------------------------------------

| | Inflation
rates of the United States and Mexico and investors expectations concerning inflation
rates;
|- | -------------------------------------------------------------------------------------------------------

| | Interest
rates of the United States and Mexico and investors expectations concerning interest
rates;
|- | -----------------------------------------------------------------------------------------------------

| | Investment
and trading activities of mutual funds, hedge funds and currency funds; and
|- | --------------------------------------------------------------------------------------

| | Global
or regional political, economic or financial events and situations.
|- | --------------------------------------------------------------------------

In addition, the Mexican Peso may not
maintain its long-term value in terms of purchasing power in the future. When the price of
the Mexican Peso declines, the Sponsor expects the price of a Share to decline as well.

3

---

The USD/Mexican Peso exchange
rate, like foreign exchange rates in general, can be volatile and difficult to predict.
This volatility could materially and adversely affect the performance of the Shares.

Foreign exchange rates are influenced
by the factors identified immediately above and may also be influenced by: changing supply
and demand for a particular currency; monetary policies of governments (including exchange
control programs, restrictions on local exchanges or markets and limitations on foreign
investment in a country or on investment by residents of a country in other countries);
changes in balances of payments and trade; trade restrictions; and currency devaluations
and revaluations. Also, governments from time to time intervene in the currency markets,
directly and by regulation, in order to influence prices directly. These events and
actions are unpredictable. The resulting volatility in the USD/Mexican Peso exchange rate
could materially and adversely affect the performance of the Shares.

If interest earned by the Trust
does not exceed expenses, the Trustee will withdraw Mexican Peso from the Trust to pay
these excess expenses which will reduce the amount of Mexican Peso represented by each
Share on an ongoing basis and may result in adverse tax consequences.

Each outstanding Share represents a
fractional, undivided interest in the Mexican Peso held by the Trust. Although the Trust
generates interest, it is possible that the amount of interest earned may not exceed
expenses, in which case the Trustee will withdraw Mexican Pesos from the Trust to pay
these excess expenses. As a result, the amount of Mexican Pesos represented by each Share
may gradually decline over time. This is true even if additional Shares are issued in
exchange for additional deposits of Mexican Pesos into the Trust, as the amount of Mexican
Pesos required to create Shares will proportionately reflect the amount of Mexican Pesos
represented by the Shares outstanding at the time of creation. Assuming a constant Mexican
Peso price, if expenses exceed interest earned, the trading price of the Shares will
gradually decline relative to the price of Mexican Pesos as the amount of Mexican Pesos
represented by the Shares gradually declines. In this event, the Shares will only maintain
their original price if the price of Mexican Pesos increases.

Investors should be aware that a
gradual decline in the amount of Mexican Pesos represented by the Shares may occur
regardless of whether the trading price of the Shares rises or falls in response to
changes in the price of Mexican Pesos. The estimated ordinary operating expenses of the
Trust, which accrue daily, are described in Business  The Trust  Trust
Expenses.

The payment of expenses by the Trust
will result in a taxable event to Shareholders.  To the extent Trust expenses exceed
interest paid to the Trust, a gain or loss may be recognized by Shareholders depending on
the tax basis of the tendered Mexican Pesos.

If the Trust incurs expenses in
USD, the Trust is required to sell Mexican Pesos to pay these expenses. The sale of the
Trusts Mexican Pesos to pay expenses in USD at a time of low Mexican Peso prices
could adversely affect the value of the Shares.

The Trustee will sell Mexican Pesos
held by the Trust if necessary to pay Trust expenses if any incurred in USD, irrespective
of then-current Mexican Pesos prices. The Trust is not actively managed and no attempt
will be made to buy or sell Mexican Peso to protect against or to take advantage of
fluctuations in the price of Mexican Pesos. Consequently, the Trusts Mexican Pesos
may be sold at a time when the Mexican Peso price is low, resulting in a negative effect
on the value of the Shares.

Purchasing activity in the Mexican
Peso market associated with the purchase of Baskets from the Trust may cause a temporary
increase in the price of Mexican Pesos. This increase may adversely affect an investment
in the Shares.

Purchasing activity associated with
acquiring the Mexican Pesos required for deposit into the Trust in connection with the
creation of Baskets may temporarily increase the market price of Mexican Pesos, which will
result in higher prices for the Shares. Temporary increases in the market price of Mexican
Pesos may also occur as a result of the purchasing activity of other market participants.
Other market participants may attempt to benefit from an increase in the market price of
Mexican Pesos that may result from increased purchasing activity of Mexican Pesos
connected with the issuance of Baskets. Consequently, the market price of Mexican Pesos
may decline immediately after Baskets are created. If the price of Mexican Peso declines,
then it is anticipated that the trading price of the Shares will also decline. In
addition, if the Trust experiences a significant increase in its expenses due to an
unexpected event, then it is anticipated that the unexpected expenses would reduce the NAV
of the Trust, which would cause the trading price of the Shares to decline even if the
price of Mexican Pesos did not decline.

The Deposit Accounts are not
entitled to payment at any office of JPMorgan Chase Bank, N.A. located in the United
States.

The federal laws of the United States
prohibit banks located in the United States from paying interest on unrestricted demand
deposit accounts. Therefore, payments out of the Deposit Accounts will be payable only at
the London branch of JPMorgan Chase Bank, N.A., located in England. The Trustee will not
be entitled to demand payment of these accounts at any office of JPMorgan Chase Bank, N.A.
that is located in the United States. JPMorgan Chase Bank, N.A. will not be required to
repay the deposit if its London branch cannot repay the deposit due to an act of war,
insurrection or civil strife or an action by a foreign government or instrumentality
(whether de jure or de facto) in England.

Shareholders do not have the
protections associated with ownership of a demand deposit account insured in the United
States by the Federal Deposit Insurance Corporation nor the full protection provided for
bank deposits under English law.

Neither the Shares nor the Deposit
Accounts and the Mexican Pesos deposited in them are a deposit insured against loss by the
FDIC or any other federal agency. Deposits may have only limited protection under the
Financial Services Compensation Scheme of England.

Mexican Pesos deposited in the
Deposit Accounts by an Authorized Participant are commingled with Mexican Pesos deposited
by other Authorized Participants and are held by the Depository in either the primary
deposit account or the secondary deposit account of the Trust. Mexican Pesos held in the
Deposit Accounts are not segregated from the Depositorys other assets. If the
Depository becomes insolvent, then its assets might not be adequate to satisfy a claim by
the Trust or any Authorized Participant. In addition, in the event of the insolvency of
the Depository or the U.S. bank of which it is a branch, there may be a delay and costs
incurred in recovering the Mexican Pesos held in the Deposit Accounts.

The Trust has no proprietary rights
in or to any specific Mexican Pesos held by the Depository and will be an unsecured
creditor of the Depository with respect to the Mexican Pesos held in the Deposit Accounts
in the event of the insolvency of the Depository or the U.S. bank of which it is a branch.
In the event the Depository or the U.S. bank of which it is a branch becomes insolvent,
the Depositorys assets might not be adequate to satisfy a claim by the Trust or any
Authorized Participant for the amount of Mexican Pesos deposited by the Trust or the
Authorized Participant, in such event, the Trust and any Authorized Participant will
generally have no right in or to assets other than those of the Depository.

In the case of insolvency of the
Depository or JPMorgan Chase Bank, N.A., the U.S. bank of which the Depository is a
branch, a liquidator may seek to freeze access to the Mexican Pesos held in all accounts
by the Depository, including the Deposit Accounts. The Trust and the Authorized
Participants could incur expenses and delays in connection with asserting their claims.
These problems would be exacerbated by the reality that the Deposit Accounts will not be
held in the U.S. but instead will be held at the London branch of a U.S. national bank,
where it will be subject to English insolvency law. Further, under U.S. law, in the case
of the insolvency of JPMorgan Chase Bank, N.A., the claims of creditors in respect of
accounts (such as the Trusts Deposit Accounts) that are maintained with an overseas
branch of JPMorgan Chase Bank, N.A. will be subordinate to claims of creditors in respect
of accounts maintained with JPMorgan Chase Bank, N.A. in the U.S., greatly increasing the
risk that the Trust and the Trusts beneficiaries would suffer a loss.

Shareholders do not have the
protections associated with ownership of shares in an investment company registered under
the Investment Company Act of 1940.

The Investment Company Act is
designed to protect investors by preventing: insiders from managing investment companies
to their benefit and to the detriment of public investors; the issuance of securities
having inequitable or discriminatory provisions; the management of investment companies by
irresponsible persons; the use of unsound or misleading methods of computing earnings and
asset value; changes in the character of investment companies without the consent of
investors; and investment companies from engaging in excessive leveraging. To accomplish
these ends, the Investment Company Act requires the safekeeping and proper valuation of
fund assets, restricts greatly transactions with affiliates, limits leveraging, and
imposes governance requirements as a check on fund management. The Investment Company Act
applies to a range of investment company structures, but, in practice, primarily regulates
a company holding a portfolio of investment securities such as publicly traded stocks,
bonds and money market instruments: selected by an affiliated investment adviser pursuant
to the companys stated investment objectives, policies, restrictions, strategies and
techniques where the investment adviser manages the portfolio and otherwise operates the
company on a day-to-day basis for a management fee and other charges and expenses and, in
doing so, has conflicts of interest with the company; valued, priced for sale and
redemption, physically held and traded in securities markets pursuant to computational,
custody and brokerage and other transactional requirements peculiar to such a portfolio of
investment securities; and overseen by the companys board of directors that is
elected, constituted and governed pursuant to specified standards developed in the context
of such a portfolio of investment securities.

The Trust is not registered as an
investment company under the Investment Company Act and is not required to register under
that Act. Consequently, Shareholders do not have the regulatory protections afforded to
investors in registered investment companies.

Shareholders do not have the
rights enjoyed by investors in certain other financial instruments.

As interests in a grantor trust, the
Shares have none of the statutory rights normally associated with the ownership of shares
of a business corporation, including, for example, the right to bring
oppression or derivative actions. Apart from the rights afforded
to them by federal and state securities laws, Shareholders have only those rights relative
to the Trust, the Trust property and the Shares that are set forth in the Depositary Trust
Agreement. In this connection, the Shareholders have limited voting and distribution
rights. They do not have the right to elect directors. See Business  The
Shares  Limited Rights for a description of the limited rights of the
Shareholders.

The Shares may trade at a price
which is at, above, or below the NAV per Share.

The NAV per Share fluctuates with
changes in the market value of the Trusts assets. The market price of Shares can be
expected to fluctuate in accordance with changes in the NAV per Share, but also in
response to market supply and demand. As a result, the Shares might trade at prices at,
above or below the NAV per Share.

The interest rate earned by the
Trust, although competitive, may not be the best rate available. If the Sponsor determines
that the interest rate is inadequate, then its sole recourse is to remove the Depository
and terminate the Deposit Accounts.

The Depository is committed to
endeavor to pay a competitive interest rate on the balance of Mexican Peso in the primary
deposit account of the Trust. Interest on the primary deposit account accrues daily and is
paid monthly. The Sponsor discloses the current interest rate on the Trusts website.
If the Sponsor believes that the interest rate paid by the Depository is not adequate, the
Sponsors sole recourse is to remove the Depository and terminate the Deposit
Accounts. The Depository is not paid a fee for its services to the Trust; rather,
generates income or loss based on its ability to earn a spread or
margin over the interest it pays to the Trust by using the Trusts
Mexican Peso to make loans or in other banking operations. For these reasons, you should
not expect that the Trust will be paid the best available interest rate at any time or
over time.

The Depository owes no fiduciary
duties to the Trust or the Shareholders, is not required to act in their best interest and
could resign or be removed by the Sponsor, which would trigger early termination of the
Trust.

The Depository is not a trustee for
the Trust or the Shareholders. As stated above, the Depository is not obligated to
maximize the interest rate paid to the Trust. In addition, the Depository has no duty to
continue to act as the depository of the Trust. The Depository can terminate its role as
depository for any reason whatsoever upon 90 days notice to the Trust. Such a
termination might result, for example, if the Sponsor determines that the interest rate
paid by the Depository is inadequate. In the event that the Depository were to resign or
be removed, the Trust will be terminated.

# Shareholders may incur
significant fees upon the termination of the Trust.

The occurrence of any one of several
events would either require the Trust to terminate or permit the Sponsor to terminate the
Trust. For example, if the Depository were to resign or be removed, then the Sponsor would
be required to terminate the Trust. Shareholders tendering their Shares within 90 days of
the Trusts termination will receive the amount of Mexican Pesos represented by their
Shares. Shareholders may incur significant fees if they choose to convert the Mexican
Pesos they receive to U.S. Dollars.

Redemption orders are subject to
rejection by the Trustee under certain circumstances.

The Trustee will reject a redemption
order if the order is not in proper form as described in the Participant Agreement or if
the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such
rejection could adversely affect a redeeming Shareholder. For example, the resulting delay
would adversely affect the value of the Shareholders redemption distribution if the
NAV were to decline during the delay. In accordance with the Depositary Trust Agreement,
the Sponsor and the Trustee disclaim any liability for any loss or damage that may result
from any such rejection.

Substantial sales of Mexican Peso
by the official sector could adversely affect an investment in the Shares.

The official sector consists of
central banks, other governmental agencies and multi-lateral institutions that buy, sell
and hold Mexican Pesos as part of their reserve assets. The official sector holds a
significant amount of Mexican Pesos that can be mobilized in the open market. In the event
that future economic, political or social conditions or pressures require members of the
official sector to sell their Mexican Peso simultaneously or in an uncoordinated manner,
the demand for Mexican Pesos might not be sufficient to accommodate the sudden increase in
the supply of Mexican Pesos to the market. Consequently, the price of the Mexican Pesos
could decline, which would adversely affect an investment in the Shares.

Shareholders that are not
Authorized Participants may only purchase or sell their Shares in secondary trading
markets.

Only Authorized Participants may
create or redeem Baskets of Shares through the Trust. All other investors that desire to
purchase or sell Shares must do so through NYSE Arca or in other markets, if any, in which
the Shares are traded.

The liability of the Sponsor and
the Trustee under the Depositary Trust Agreement is limited and, except as set forth in
the Depositary Trust Agreement, they are not obligated to prosecute any action, suit or
other proceeding in respect of any Trust property.

The Depositary Trust Agreement
provides that neither the Sponsor nor the Trustee assumes any obligation or is subject to
any liability under the Trust Agreement to any Shareholder, except that they each agree to
perform their respective obligations specifically set forth in the Depositary Trust
Agreement without negligence or bad faith. Additionally, neither the Sponsor nor the
Trustee is obligated to, although each may in its respective discretion, prosecute any
action, suit or other proceeding in respect of any Trust property. The Depositary Trust
Agreement does not confer upon Shareholders the right to prosecute any such action, suit
or other proceeding.

The Depositary Trust Agreement may
be amended to the detriment of Shareholders without their consent.

The Sponsor and the Trustee may amend most
provisions (other than those addressing core economic rights) of the Depositary Trust
Agreement without the consent of any Shareholder. Such an amendment could impose or
increase fees or charges borne by the Shareholders. Any amendment that increases fees or
charges (other than taxes and other governmental charges, registration fees or other
expenses), or that otherwise prejudices any substantial existing rights of Shareholders,
will not become effective until 30 days after written notice is given to Shareholders.

The License Agreement with The
Bank of New York may be terminated by The Bank of New York in the event of a material
breach. Termination of the License Agreement might lead to early termination and
liquidation of the Trust.

The Bank of New York
(BNY) and an affiliate of the Sponsor have entered into a License Agreement
granting the Sponsors affiliate a license to certain patent applications made by BNY
covering systems and methods for securitizing a commodity. The Sponsors affiliate
has sublicensed the license to the Sponsor. The license is limited to a non-exclusive
grant for the life of BNYs patents and patent applications. The License Agreement
provides that each of the parties may provide notice of intent to terminate the License
Agreement in the event the other party commits a material breach. If the License Agreement
is terminated and one or more of BNYs patent applications issue as patents, then BNY
may claim that the operation of the Trust violates its patent or patents and seek an
injunction forcing the Trust to cease operation and the Shares to cease trading. In that
case, the Trust might be forced to terminate and liquidate, which would adversely affect
Shareholders.

# Item 7.   MANAGEMENTS
DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

# MOVEMENTS IN THE PRICE
OF THE MEXICAN PESO

The investment objective of the Trust
is for the Shares to reflect the price of the Mexican Peso plus accrued interest, less the
expenses of the Trusts operations. The Shares are intended to provide institutional
and retail investors with a simple, cost-effective means of gaining investment benefits
similar to those of holding Mexican Peso. Each outstanding Share represents a proportional
interest in the Mexican Pesos held by the Trust. The following chart provides recent
trends on the price of the Mexican Peso. The chart illustrates movements in the price of
the Mexican Peso in USD and is based on the Noon Buying Rate as determined by the Federal
Reserve Bank of New York.



Historical values of the Noon Buying
Rate can be obtained at http://www.ny.frb.org/markets/fxrates/noon.cfm.

# NAV PER SHARE; VALUATION
OF THE MEXICAN PESO

The following chart illustrates the
movement in the price of the Shares based on NAV per Share and the bid and
ask midpoint offered on the NYSE (prior to October 30, 2007) and NYSE Arca (on
or after October 30, 2007) as of the Noon Buying Rate versus the corresponding Mexican
Peso (expressed as a multiple of 1,000 Mexican Pesos  Noon Buying Rate x 1,000):

# LIQUIDITY

The Sponsor is not aware of any
trends, demands, conditions or events that are reasonably likely to result in material
changes to the Trusts liquidity needs. The Trusts Depository, JPMorgan Chase,
London branch, maintains two deposit accounts for the Trust, a primary deposit account
that earns interest and a secondary deposit account that does not earn interest. Interest
on the primary deposit account accrues daily and is paid monthly. The interest rate paid
as of October 31, 2007 was an annual nominal rate of 5.53%. The following chart provides
the daily rate paid by the Depository since the Shares began trading on June 26, 2006:



11

---

In exchange for a fee, the Sponsor
bears most of the expense incurred by the Trust. As a result, the only ordinary expense of
the Trust during the period covered by this report was the Sponsors fee. Each month
the Depository deposits into the secondary deposit account accrued but unpaid interest and
the Trustee, withdraws Mexican Pesos from the secondary deposit account to pay the accrued
Sponsors fee for the previous month plus other Trust expenses, if any. When the
interest deposited exceeds the sum of the Sponsors fee for the prior month plus
other Trust expenses, if any, the Trustee converts the excess into USD at a prevailing
market rate and distributes the USD as promptly as practicable to Shareholders on a pro
rata basis (in accordance with the number of Shares that they own). Distributions paid
during the current reporting period follow (annualized yield reflects the estimated annual
yield an investor would receive if a monthly distribution stayed the same for the entire
year going forward, and is calculated by annualizing the monthly distribution and dividing
by the Trust NAV for the dates listed below):

|FXM Distribution History
|------------------------
|
|10/1/2007               
|9/4/2007                
|8/1/2007                

# CRITICAL ACCOUNTING
ESTIMATES

The preparation of financial
statements in conformity with accounting principles generally accepted in the United
States of America requires the Sponsors management to make estimates and assumptions
that affect the reported amounts of the assets and liabilities and disclosures of
contingent liabilities at the date of the financial statements and the reported amounts of
revenue and expenses during the period covered by this report.

In addition to the description below,
please refer to Note 2 to the consolidated financial statements for further discussion of
our accounting policies.

The Trustee calculates the
Trusts NAV each business day. For NAV calculation purposes, Mexican Peso Deposits
(cash) are translated at the Noon Buying Rate as determined and published by the Federal
Reserve Bank of New York as of 12:00 PM (New York time) on each day that NYSE Arca is open
for regular trading. If, on a particular evaluation day, the Noon Buying Rate has not been
determined and announced by 2:00 PM (New York time), then the most recent Noon Buying Rate
is used to determine the NAV of the Trust unless the Trustee, in consultation with the
Sponsor, determines that such price is inappropriate to use as the basis for such
valuation.

The functional currency of the Trust
is the Mexican Peso in accordance with Financial Accounting Standard 52, Foreign Currency
Translation.

# RESULTS OF OPERATIONS

The Trust was formed on June 8, 2006
and the Shares commenced trading on the NYSE on June 26, 2006. The primary listing of the
Shares was transferred to NYSE Arca on October 30, 2007. As of October 31, 2006 the number
of Mexican Peso owned by the Trust was 100,000,000 resulting in a redeemable capital share
value of $9,335,391. During fiscal year end October 31, 2007 an additional 350,000 Shares
had been created in exchange for 350,000,000 Mexican Pesos and 200,000 Shares had been
redeemed in exchange for 200,000,000 Mexican Pesos. As of October 31, 2007 the number of
Mexican Peso owned by the Trust was 250,000,000 resulting in a redeemable capital share
value of $23,486,661.

# Report of Independent
Registered Public Accounting Firm

To the Shareholders of
CurrencySharesSM Mexican Peso Trust:

In our opinion, the accompanying
statements of financial condition and the related statements of income and comprehensive
income, of changes in shareholders equity and of cash flows present fairly, in all
material respects, the financial position of CurrencySharesSM Mexican Peso
Trust (the Trust) at October 31, 2007 and October 31, 2006, and the results
of its operations, its changes in shareholders equity and its cash flows for the
year ended October 31, 2007 and for the period June 8, 2006 (commencement of operations)
through October 31, 2006 in conformity with accounting principles generally accepted in
the United States of America.  These financial statements are the responsibility of the
Trusts management.  Our responsibility is to express an opinion on these financial
statements based on our audits.  We conducted our audits of these statements in
accordance with the standards of the Public Company Accounting Oversight Board (United
States).  Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our opinion.

# Notes to Financial
Statements

|1. | Organization
and Description of the Trust
|-- | -----------------------------------------

The CurrencySharesSM
Mexican Peso Trust (the Trust) was formed under the laws of the State of New
York on June 8, 2006 when Rydex Specialized Products LLC d/b/a Rydex
Investments (the Sponsor) deposited 1,000 Mexican Peso in the
Trusts primary deposit account held by JPMorgan Chase Bank N.A., London Branch (the
Depository). The Sponsor is a Delaware limited liability company whose sole
member is PADCO Advisors II, Inc. (also d/b/a Rydex Investments). The Sponsor
is responsible for, among other things, overseeing the performance of The Bank of New York
(the Trustee) and the Trusts principal service providers, including the
preparation of financial statements. The Trustee is responsible for the day-to-day
administration of the Trust.

The investment objective of the Trust
is for the Trusts shares (the Shares) to reflect the price of the
Mexican Peso plus accrued interest less the Trusts expenses and liabilities. The
Shares are intended to provide investors with a simple, cost-effective means of gaining
investment benefits similar to those of holding Mexican Pesos. The Trusts assets
primarily consist of Mexican Pesos on demand deposit in two deposit accounts maintained by
the Depository: a primary deposit account which earns interest and a secondary deposit
account which does not earn interest. The secondary deposit account is used to account for
interest received and paid out on creations and redemptions of blocks of 50,000 Shares
(Baskets). The secondary account is also used to account for interest earned
on the primary deposit account, pay Trust expenses and distribute any excess interest to
holders of Shares (Shareholders) on a monthly basis.

The accompanying audited financial
statements were prepared in accordance with accounting principles generally accepted in
the United States of America.

|2. | Significant
Accounting Policies
|-- | -------------------------------

| | A. | Use
of Estimates
| | -- | ----------------

The preparation of financial
statements in conformity with accounting principles generally accepted in the United
States of America requires management to make estimates and assumptions that affect the
reported amounts of the assets, liabilities and disclosures of contingent liabilities at
the date of the financial statements and the reported amounts of revenue and expenses
during the period. Actual results could differ from those estimates.

| | B. | Foreign
Currency Translation
| | -- | ----------------------------

The Trustee calculates the
Trusts net asset value (NAV) each business day, as described in Note 4.
For NAV calculation purposes, Mexican Peso Deposits (cash) are translated at the Noon
Buying Rate, which is the U.S. Dollar (USD)/ Mexican Peso exchange rate as
determined and published by the Federal Reserve Bank of New York as of 12:00 PM (New York
time) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust
is the Mexican Peso in accordance with Financial Accounting Standard (FAS) 52,
Foreign Currency Translation. For financial statement reporting purposes, the U.S. Dollar
is the reporting currency. As a result, the financial statements are translated from
Mexican Pesos to USD. The Noon Buying Rate on the last day of the period is used for
translation in the statements of financial condition. The average Noon Buying Rate for the
period is used for translation in the statement of income and comprehensive income and the
statement of cash flows. Any currency translation adjustment is included in comprehensive
income.

---

| | C. | Federal
Income Taxes
| | -- | --------------------

The Trust is treated as a
grantor trust for federal income tax purposes and, therefore, no provision for
federal income taxes is required. Interest, gains and losses are passed
through to the Shareholders.

Shareholders generally will be
treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share
of the assets held in the Trust. Shareholders also will be treated as if they directly
received their respective pro-rata shares of the Trusts income, if any, and as if
they directly incurred their respective pro-rata shares of the Trusts expenses. The
acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be
a taxable event to the Shareholder.

The Sponsors fee accrues daily
and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S.
Shareholder generally will be required to take into account as an expense its allocable
share of the USD-equivalent of the amount of the Sponsors fee that is accrued on
each day, with such USD-equivalent being determined by the currency exchange rate that is
in effect on the respective day. To the extent that the currency exchange rate on the date
of payment of the accrued amount of the Sponsors fee differs from the currency
exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a
currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate
taxable income except for gain (if any) upon the sale of Mexican Pesos and interest
income. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax
with respect to gain recognized upon the sale or other disposition of Shares, or upon the
sale of Mexican Pesos by the Trust, unless: (1) the non-U.S. Shareholder is an individual
and is present in the United States for 183 days or more during the taxable year of the
sale or other disposition, and the gain is treated as being from United States sources; or
(2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a
trade or business in the United States.

A non-U.S. Shareholders share
of any interest income earned by the Trust generally will not be subject to U.S. federal
income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected
with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

| | D. | Revenue
Recognition
| | -- | -------------------

Interest on the primary deposit
account accrues daily as earned and is received on a monthly basis.

| | E. | Dividends
| | -- | ---------

To the extent that the interest earned
by the Trust exceeds the sum of the Sponsors fee for the prior month plus other
Trust expenses, if any, the Trust will distribute, as a dividend, the excess interest
earned in Mexican Pesos effective on the first business day of the subsequent month. The
Trustee will direct that the excess Mexican Pesos be converted into USD at the prevailing
market rate and the Trustee will distribute the USD as promptly as practicable to
Shareholders on a pro rata basis (in accordance with the number of Shares that they own).
For the month of October 2007, an income distribution of $0.48717 per share was paid on
November 8, 2007.

|3. | Mexican
Peso Deposits
|-- | ---------------------

Mexican Peso principal deposits are
held in a Mexican Peso-denominated, interest-bearing demand account. For the year ending
October 31, 2007, there were Mexican Peso principal deposits of 350,000,000 and Mexican
Peso principal redemptions of 200,000,000 resulting in an ending Mexican Peso principal
balance of 250,000,000. This equates to 23,365,359 USD. For the period from June 8, 2006
(Date of Inception) to October 31, 2006, there were Mexican Peso principal deposits of
250,000,000 and Mexican Peso principal redemptions of 150,001,000 resulting in an ending
Mexican Peso principal balance of 100,000,000. This equated to 9,287,638 USD. In addition,
net interest associated with creation and redemption activity is held in a Mexican Peso
-denominated non-interest-bearing account, and any balance is distributed in full as part
of the monthly income distributions.

|4. | Redeemable
Capital Shares
|-- | -------------------------

Shares are classified as
redeemable for financial statement purposes, since they are subject to
redemption. Shares are issued and redeemed continuously in Baskets in exchange for Mexican
Pesos. Individual investors cannot purchase or redeem Shares in direct transactions with
the Trust. Only Authorized Participants (as defined below) may place orders to create and
redeem Baskets. An Authorized Participant is a DTC participant that is a registered
broker-dealer or other institution eligible to settle securities transactions though the
book-entry facilities of the DTC and which has entered into a contractual arrangement with
the Trust and the Sponsor governing, among other matters, the creation and redemption
process. Authorized Participants may redeem their Shares at any time in Baskets.

Due to expected continuing creations
and redemptions of Baskets and the three-day period for settlement of each creation or
redemption, the Trust reflects Shares created as a receivable. Shares redeemed are
reflected as a liability on the trade date. Outstanding Shares are reflected at a
redemption value, which is the NAV per Share at the period end date. Adjustments to
redeemable capital shares at redemption value are recorded against retained earnings, or,
in the absence of retained earnings, by charges against the cumulative translation
adjustment.

Activity in redeemable capital Shares
is as follows:

F-9

---

The Trustee will calculate the
Trusts NAV each business day. To calculate the NAV, the Trustee will subtract the
Sponsors accrued fee through the previous day from the Mexican Pesos held by the
Trust (including all unpaid interest accrued through the preceding day) and calculate the
value of the Mexican Pesos in USD based upon the Noon Buying Rate. If, on a particular
evaluation day, the Noon Buying Rate has not been determined and announced by 2:00 PM (New
York time), then the most recent Federal Reserve Bank of New York determination of the
Noon Buying Rate shall be used to determine the NAV of the Trust unless the Trustee, in
consultation with the Sponsor, determines that such price is inappropriate to use as the
basis for such valuation. In the event that the Trustee and the Sponsor determine that the
most recent Federal Reserve Bank of New York determination of the Noon Buying Rate is not
an appropriate basis for valuation of the Trusts Mexican Pesos, they shall determine
an alternative basis for such evaluation to be employed by the Trustee. The Trustee also
determines the NAV per Share, which equals the NAV of the Trust divided by the number of
outstanding Shares. Shares deliverable under a purchase order are considered outstanding
for purposes of determining NAV per Share; Shares deliverable under a redemption order are
not considered outstanding for this purpose.

|5. | Sponsors
Fee
|-- | -------------

The Sponsors fee accrues daily
at an annual nominal rate of 0.40% of the Mexican Pesos in the Trust (including all unpaid
interest but excluding unpaid fees, each as accrued through the immediately preceding day)
and is paid monthly.

The Sponsor assumes and pays the
following administrative and marketing expenses incurred by the Trust: the Trustees
monthly fee, NYSE Arca listing fees, SEC registration fees, typical maintenance and
transaction fees of the Depository, printing and mailing costs, audit fees and expenses,
up to $100,000 per year in legal fees and expenses, and applicable license fees. The
Sponsor has also paid the costs of the Trusts organization and the initial sales of
the Shares, which were approximately $232,000 when the Trust was formed.

In certain exceptional cases the
Trust will pay for some expenses in addition to the Sponsors fee. These exceptions
include expenses not assumed by the Sponsor (i.e., expenses other than those identified in
the preceding paragraph), taxes and governmental charges, expenses and costs of any
extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or
action taken by the Trustee or the Sponsor to protect the Trust or the interests of
Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, and
legal expenses in excess of $100,000 per year.

|6. | Related
Parties
|-- | ---------------

The Sponsor is a related party of the
Trust. The Sponsor oversees the performance of the Trustee and the Trusts principal
service providers, including the preparation of financial statements, but does not
exercise day-to-day oversight over the Trustee or the Trusts service providers. The
Sponsor has paid the costs of the Trusts organization and the initial sales of the
Shares, as described in Note 5.

|7. | Concentration
Risk
|-- | ------------------

All of the Trusts assets are
Mexican Pesos, which creates a concentration risk associated with fluctuations in the
price of the Mexican Peso. Accordingly, a decline in the price of the Mexican Peso to USD
exchange rate will have an adverse effect on the value of the Shares. Factors that may
have the effect of causing a decline in the price of the Mexican Peso include national
debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign
interest rates, investment and trading activities of institutions and global or regional
political, economic or financial events and situations. Substantial sales of Mexican Pesos
by the official sector (central banks, other governmental agencies and related
institutions that buy, sell and hold Mexican Pesos as part of their reserve assets) could
adversely affect an investment in the Shares.

|8. | Commitments
and Contingencies
|-- | -----------------------------

Under the Trusts organizational
documents, the Sponsor is indemnified against any liability or expense it incurs without
negligence, bad faith or willful misconduct on its part. The Trusts maximum exposure
under these arrangements is unknown, as this would involve future claims that may be made
against the Trust that have not yet occurred.
