This
      Quarterly Report on Form 10-Q contains various "forward-looking statements"
      within the meaning of Section 27A of the Securities Act of 1933, as amended,

      Section 21E of the Securities Exchange Act of 1934, as amended, and within

      statements usually include the verbs, "anticipates," "believes," "estimates,"
      "expects," "intends," "plans," "projects," "understands" and other verbs
      suggesting uncertainty. We remind readers that forward-looking statements are
      merely predictions and therefore inherently subject to uncertainties and other
      factors and involve known and unknown risks that could cause the actual results,
      performance, levels of activity, or achievements, or industry results, to be
      materially different from any future results, performance, levels of activity,
      or our achievements expressed or implied by such forward-looking statements.
      Readers are cautioned not to place undue reliance on these forward-looking
      statements, which speak only as of the date hereof. The Trust undertakes no
      obligation to publicly release any revisions to these forward-looking statements
      to reflect events or circumstances after the date hereof or to reflect the

**Claymore
      MACROshares Oil Down Holding Trust**


**NOTES
      TO THE UNAUDITED FINANCIAL STATEMENTS**


**as
      of June 30, 2007**





A.
            Organization





MACRO
      Securities Depositor, LLC (the “ **Depositor** ”), a
      Delaware limited liability company with MacroMarkets LLC and Claymore Group
      Inc.
      (collectively referred to as “ **Related
      Party** ”)
      as its
      only two members, formed
      the Claymore MACROshares Oil Down Tradeable Trust (the “ **Down-MACRO
      Tradeable Trust** ”),
      the
      Claymore MACROshares Oil Up Tradeable Trust (the “ **Up-MACRO
      Tradeable Trust** ”),
      the
      Claymore MACROshares Oil Down Holding Trust (the “ **Down-MACRO
      Holding Trust** ”)
      and
      the Claymore MACROshares Oil Up Holding Trust (the “ **Up-MACRO
      Holding Trust** ”).
      Each
      of the trusts was formed under the laws of the State of New York on November
      15,
      2006.





The
      Down-MACRO Holding Trust and the Up-MACRO Holding Trust are referred to as
      “ **Paired
      Holding Trusts** ”.
      The
      descriptions of the Paired Holding Trusts in these notes reflect the trust
      agreements as amended on November 24, 2006. Operations of the Down-MACRO Holding
      Trust and Down-MACRO Tradeable Trust commenced on November 29, 2006. No
      creations or other activity occurred between November 24, 2006 and the
      commencement date. Each of the Paired Holding Trusts issues shares (which are
      referred to, respectively, as “ **Down-MACRO
      Holding Shares** ”
and
      “ **Up-MACRO
      Holding Shares** ,”
and,
      collectively, as “ **Paired
      Holding Shares** ”)
      in
      minimum aggregations called “ **MACRO
      Units** ,”
each
      of which consists of 50,000 Down-MACRO Holding Shares and 50,000 Up-MACRO
      Holding Shares. The
      objective of the Paired Holding Trusts is, in the case of the Down-MACRO Holding
      Trust, to provide investors with investment returns that correspond inversely
      with changes in the price of NYMEX crude oil futures contracts within the range
      from (i) zero to (ii) twice the starting level of $60 (the “ **Starting
      Level** ”)
      and,
      in the case of the Up-MACRO Holding Trust, to provide investors with investment
      returns that correspond with the price of NYMEX crude oil futures within the
      range from (i) zero to (ii) twice the Starting Level. **** The
      Starting Level was $60, therefore the price range within which the Paired
      Holding Trusts are expected to provide a return to both of the Paired Holding
      Shares is $0 to $120. There can be no assurance that the Paired Holding Trusts
      will achieve their investment objective.





The
      Depositor, Investors
      Bank & Trust Company, as trustee (in
      such
      capacity, the “ **Trustee** ” ) ,
      Claymore Securities, Inc., as administrative agent and marketing agent (in
      such
      capacities, the “ **Administrative
      Agent** ”
and
      the
“ **Marketing
      Agent** ” )
      and
      MACRO Financial, LLC as an additional marketing agent (in such capacity, the
      “ **Marketing
      Agent** ”),
      have
      entered into trust agreements that govern the activities of the Down-MACRO
      Tradeable Trust and Down-MACRO Holding Trust and specify the terms of the shares
      issued by the Down-MACRO Tradeable Trust (the “ **Down-MACRO
      Tradeable Shares** ”)
      and
      the Down-MACRO Holding Shares, respectively. The Down-MACRO Tradeable Trust
      issues the Down-MACRO Tradeable Shares on a continuous basis in exchange for
      deposits of Down-MACRO Holding Shares. Down-MACRO Tradeable Shares are only
      issued or exchanged for the underlying Down-MACRO Holding Shares in connection
      with deposit of Down-MACRO Holding Shares into the Down-MACRO Tradeable Trust
      or
      the withdrawal of Down-MACRO Holding Shares from the Down-MACRO Tradeable Trust.
      One Down-MACRO Tradeable Share is issued for each Down-MACRO Holding Share
      deposited into the Down-MACRO Tradeable Trust. The per share “ **underlying
      value** ”
of
      one
      Down-MACRO Tradeable Share is always equal to the underlying value of one
      Down-MACRO Holding Share. The underlying value of the Down-MACRO Holding Trust’s
      shares represents that portion of the proceeds of the assets of the Down-MACRO
      Holding Trust that would be distributed in conjunction with a redemption and
      as
      a final distribution upon termination if the Paired Holding Trusts were to
      settle the settlement contracts and the Down-MACRO Holding Trust were to make
      a
      final distribution on the Down-MACRO Holding Shares. The Down-MACRO Tradeable
      Trust would pass through such final distribution to holders of Down-MACRO
      Tradeable Shares. The underlying value per share of the Down-MACRO Holding
      Trust
      at June 30, 2007 was $49.34. Paired Holding Shares are only created and
      redeemed, and Down-MACRO Tradeable Shares are only created and exchanged,
      through entities who are banks, broker-dealers or other participant members
      of
      The Depository Trust Company (“ **DTC** ”)
      who
      have executed a contract with the Trustee
      and the Administrative Agent (“ **Authorized
      Participants** ” ) .
      Each
      Down-MACRO Tradeable Share represents an undivided beneficial interest in the
      pool of Down-MACRO Holding Shares deposited in the Down-MACRO Tradeable Trust.
      Issuances and redemptions of Down-MACRO Holding Shares and Down-MACRO Tradeable
      Shares are reflected in these financial statements at the value of the equity
      attributable to such shares at time of issuance or redemption, based on
      accounting principles generally accepted in the United States of America
      (“ **GAAP** ”).




5




The
      assets of the Down-MACRO Tradeable Trust consist solely of the Down-MACRO
      Holding Shares on deposit from time to time therein. Prior to November 29,
      2006,
      the Depositor and Claymore Securities, Inc. each made an initial deposit of
      $500
      into the Down-MACRO Holding Trust and $500 into the Down-MACRO Tradeable Trust,
      for a total initial deposit into each trust of $1,000 (for each trust, the
      “ **Founders'
      Equity** ”).
      During the period ended December 31, 2006, the Founders’ Equity of both the
      Down-MACRO Holding Trust and the Down-MACRO Tradeable Trust was redeemed and
      returned to the Depositor and Claymore Securities, Inc. The Down-MACRO Tradeable
      Trust shares trade on the American Stock Exchange (“ **AMEX** ”),
      at
      negotiated prices, during “ **New
      York Business Days** ”
(any
      day on which stock exchanges and New York money center banks are open for
      business). The market price of the Down-MACRO Tradeable Shares may diverge
      from
      the closing per share underlying value of the Down-MACRO Tradeable Trust. Based
      on market demand the Down-MACRO Tradeable Shares may trade at a premium or
      a
      discount to their per share underlying value.




The
      assets of the Down-MACRO Holding Trust consist of cash, government
      securities ,
      repurchase agreements collateralized by U.S. government securities and OTC
      derivative instruments entered into between the Paired Holding
      Trusts. These derivative instruments consist of “ **S** **ettlement
      Contracts** ”
which
      provide that the Down-MACRO Holding Trust is entitled to receive from, or is
      required to make to, the Up-MACRO Holding Trust a payment at the termination
      of
      each of these contracts in
      an
      amount that reflects
      the price change
      between the settlement
      price of NYMEX crude oil futures
      contracts ( the
      “ **Closing
      Price** ”)
      at the
      time when the Settlement Contracts are terminated and the Starting Level of
      that
      price on
      November 29, 2006 .
      The
      NYMEX crude oil futures contracts that are referenced by the Paired Holding
      Trusts are (i) futures contracts that mature during the next calendar month
      succeeding the current month for any date of determination occurring on or
      after
      the first day of the current month up to but excluding the 11 th New York
      Business Day of that month and (ii) futures contracts that mature during the
      second calendar month succeeding the current calendar month for any date of
      determination occurring on or after such 11 th New York
      Business Day (provided that the switch out of next month's contract to the
      succeeding month's contract may not take place later than the 17 th day of
      each month).





For
      purposes of determining the underlying value at which Paired Holding Shares
      are
      redeemed or created, as defined in the Down-MACRO Holding Trust Agreement,
      each
      Settlement Contract is valued on each
      New York Business Day against
      the Closing Price and the resulting percentage change in the Closing Price
      from
      the Starting Level. The
      performance obligations of the Paired Holding Trusts to each other under the
      Settlement Contracts are 100% collateralized by cash, U.S. government securities and repurchase agreements backed by U.S. government
      securities that are held in each of the Paired Holding Trusts. The Down-MACRO
      Holding Trust's obligations are not leveraged and the trust realizes capital
      gains or losses only when a Settlement Contract is terminated in connection
      with
      a paired optional redemption, an early termination or the final scheduled
      termination of the Paired Holding Trusts.





The
      “ **Income
      Distribution Agreement** ”
entered
      into between the Paired Holding
      Trusts is the means for allocating between
      the Paired Holding Trusts the daily
      income accrual on the U.S.
      government securities and other assets on deposit in the trusts. Under
      the
      Income Distribution Agreement, the Down-MACRO Holding Trust is obligated to
      pay
      a portion of its income to the Up-MACRO Holding Trust or entitled to receive
      a
      portion of the Up-MACRO Holding Trust's income, based on the percentage
      difference of the Closing Price and the Starting Level on each day of the
      calendar quarter between distribution dates. The Down-MACRO Holding Trust's
      daily income for the purposes of determining underlying value recorded under
      the
      Income Distribution Agreement reflects either
      an
      asset receivable by it or a liability payable by it ,
      based
      upon the difference in the daily value of the Closing Price and its Starting
      Level. A
      payment
      is made by one of the Paired Holding Trusts to the other on each quarterly
      distribution date and the Down-MACRO Holding Trust then distributes its
      remaining income (if it had to make a payment under the Income Distribution
      Agreement) or all of its income and a portion of the income it received from
      the
      Up-MACRO Holding Trust (if it received a payment under the Income Distribution
      Agreement) as a quarterly distribution to its shareholders on or immediately
      following such quarterly distribution date.





B.
            Significant
                Accounting Policies




The
      following is a summary of the significant accounting policies that are
      consistently followed by the Down-MACRO Holding Trust in the preparation of
      its
      financial statements.




6




**Basis
      of Accounting**





The
      policies are in conformity with GAAP. The preparation of financial statements
      requires management to make estimates and assumptions that affect the reported
      amounts of assets and liabilities on the date of the financial statements and
      the reported amounts of revenues and expenses during the periods presented
      in
      the accompanying financial statements (the “ **Reporting
      Periods** ”).
      Actual results could differ from those estimates.





The
      accompanying unaudited financial statements were prepared in accordance with
      accounting principles generally accepted in the United States of America for
      interim financial information and with the instructions for Form 10-Q and the
      rules and regulations of the U.S. Securities and Exchange Commission (the
“ **SEC** ”).
      In
      the opinion of the Depositor’s management, which was responsible for the
      preparation of the financial statements on behalf of the Down-MACRO Holding
      Trust, all material adjustments, consisting only of normal recurring
      adjustments, considered necessary for a fair statement of the interim period
      financial statements have been made. Interim period results are not necessarily
      indicative of results for a full-year period. These financial statements and
      the
      notes thereto should be read in conjunction with the Trust’s financial
      statements included in the Form of 10-K as filed with the SEC on April 2,
      2007.





Under
      GAAP, U.S. government securities and repurchase agreements are accounted for
      on
      a trade date basis. Interest income, adjusted for the amortization of premium
      and accretion of discounts is earned from settlement date and is recorded on
      an
      accrual basis. Expenses are recorded on an accrual basis as incurred.





During
      the period from November 29, 2006 (commencement of operations) through June
      30,
      2007, 100% of the Down-MACRO Holding Trust Shares outstanding were held by
      the
      Down-MACRO Tradeable Trust.





**Cash
      and Cash Equivalents**





The
      Down-MACRO Holding Trust considers all highly liquid investments with original
      maturities of less than 90 days to be cash equivalents.





The
      Down-MACRO Holding Trust invests in debt securities issued by the U.S.
      government and repurchase agreements (or “ **repos** ”)
      collateralized by U.S. government securities, which have, in each case,
      remaining maturities or terms of less than ninety (90) days. The Down-MACRO
      Holding Trust may enter into repurchase agreements with banks and broker-dealers
      whereby the Down-MACRO Holding Trust acquires a U.S. debt security for cash
      and
      obtains a simultaneous commitment from the seller to repurchase the security
      at
      an agreed upon price and date.  The Down-MACRO Holding Trust, through its
      custodian, takes possession of securities that are used as collateral.  In
      connection with transactions in repos, if the seller defaults or enters into
      insolvency proceedings and the value of the collateral declines, recovery of
      cash by the Down-MACRO Holding Trust may be delayed or limited. The U.S.
      government securities and repos are valued at amortized cost, which approximates
      market value.





**The
      Settlement Contracts**





Upon
      each
      issuance of Down-MACRO holding shares as part of a MACRO Unit in a Paired
      Subsequent Issuance, the Down-MACRO Holding Trust enters into a new Settlement
      Contract with the Up-MACRO Holding Trust. For each New York Business Day, the
      Paired Optional Redemptions and Paired Subsequent Issuances ordered on that
      day
      are netted for purposes of determining how many Settlement Contracts need to
      be
      entered into or terminated on that day; however, one Settlement Contract must
      always be outstanding for one MACRO Unit of outstanding Paired Holding Shares.
      Under the Settlement Contracts, the Down-MACRO Holding Trust is either (1)
      required to deliver all or a portion of its assets (held in the form of cash,
      government securities and repos) to the Up-MACRO Holding Trust or (2) entitled
      to receive all or a portion of the assets (held in the form of the same types
      of
      assets) of the Up-MACRO Holding Trust. The
      settlement payments made or received pursuant to the Settlement Contracts are
      based on the difference
      between the
      Closing P rice and its
      Starting Level on the day on which a redemption order for Paired Holding Shares
      is delivered to the Administrative Agent. The
      final
      distribution on the Down-MACRO Holding Shares depends upon the settlement
      payment that the Down-MACRO Holding Trust will either be required to make or
      be
      entitled to receive under the Settlement Contracts when such contracts are
      settled in connection with Paired Optional Redemptions, early terminations
      or
      the final scheduled termination of the
      Down-MACRO Holding Trust.




7




The settlement obligations of the Paired Holding Trusts under the Settlement Contracts are
      fully supported by the cash, government securities and repos held by each trust.





For
      the
      purpose of determining the underlying value at which Paired Holding Shares
      are
      redeemed or created, each daily recording of the difference between the Closing
      Price and the Starting Level is referred to as the daily calculation of the
      amount due to or from the Down-MACRO Holding Trust under the Settlement
      Contract. If the Closing Price exceeds its Starting Level, a liability is
      recorded as being due to the Up-MACRO Holding Trust under the Settlement
      Contracts. If the Closing Price is less than its Starting Level, an asset
      receivable from the Up-MACRO Holding Trust is recorded under the Settlement
      Contracts. If the Closing Price equals its Starting Level, no accounting entry
      is recorded.





For
      the
      purpose of financial reporting, the settlement contracts constitute derivative
      contracts. Accordingly, the settlement contracts are recorded in the financial
      statements at fair value, as determined by the Administrative Agent. As there
      is
      no market for the settlement contracts, and no such market is expected to
      develop, the Administrative Agent determines the fair value of the settlement
      contracts by reference to various inputs, including the contractual amount
      due
      to or from the other trust, applicable market indices, and the prices of
      transactions in Down-MACRO Tradeable Shares on the AMEX. The fair value of
      the
      settlement contracts as determined in good faith by the Administrative Agent
      could differ from the value that would have been determined had a market for
      the
      settlement contracts existed, and the differences could be material. The fair
      value of the settlement contracts held by the Down-MACRO Holding Trust as of
      June 30, 2007 and on various creation or redemption dates during the Reporting
      Periods for financial reporting purposes was different from the value used
      to
      determine underlying value, as defined previously.





**Income
      Distribution Agreement**





Under
      the
      Income Distribution Agreement with the Up-MACRO Holding Trust, the Down-MACRO
      Holding Trust, on each quarterly distribution date, is either (1) required
      to
      pay all or a portion of its income from its government securities and repos,
      after deduction of a fixed number of basis points (a basis point being 1/100
      of
      one percent) for the payment of fees and expenses, to the Up-MACRO Holding
      Trust
      or (2) entitled to receive all or a portion of the Up-MACRO Holding Trust's
      income, after the Up-MACRO Holding Trust has deducted a fixed number of basis
      points for payment of its expenses and fees, based on its daily accrued income
      for each day during the preceding calendar quarter and the Closing Price for
      that day.





For
      the
      purpose of determining the underlying value at which Paired Holding Shares
      are
      redeemed or created, if the Closing Price on any New York Business Day exceeds
      its Starting Level, the Down-MACRO Holding Trust records a payment obligation
      payable to the Up-MACRO Holding Trust under the Income Distribution Agreement
      as
      a liability payable for that day. If the Closing Price is less than its Starting
      Level on any New York Business Day, the Down-MACRO Holding Trust records an
      asset receivable from the Up-MACRO Holding Trust under the Income Distribution
      Agreement. If the Closing Price equals its Starting Level, no accounting entry
      is recorded. For any
      day that is not a New York Business Day, the Closing Price from the last
      preceding New York Business Day is used to calculate the asset or liability
      under the Income Distribution Agreement for that day. The assets receivable
      and
      liabilities payable for each day by the Down-MACRO Holding Trust are netted
      in
      order to determine whether it will make a payment to, or be entitled to receive
      a payment from, the Up-MACRO Holding Trust on the quarterly distribution date,
      prior to distributing its income to its shareholders.





For
      the
      purpose of financial reporting, the income distribution contract constitutes
      a
      derivative contract. Accordingly, the income distribution contract is recorded
      in the financial statements at fair value, as determined by the Administrative
      Agent. As there is no market for the income distribution contract, and no such
      market is expected to develop, the Administrative Agent determines the fair
      value of the income distribution contract by reference to various inputs,
      including the contractual amount due to or from the other trust as well as
      the
      factors considered in the valuation of the settlement contracts as described
      above. The fair value of the income distribution contract as determined in
      good
      faith by the Administrative Agent could differ from the value that would have
      been determined had a market for the income distribution contract existed,
      and
      the differences could be material. The fair value of the income distribution
      contract held by the Down-MACRO Holding Trust as of June 30, 2007 and on various
      creation or redemption dates during the Reporting Periods for financial
      reporting purposes was different from the value used to determine underlying
      value, as defined previously.




8




**Federal
      Income Taxes**




The
      Down-MACRO Holding Trust is treated as a partnership for federal income tax
      purposes and, therefore, no provision for federal income taxes is required.




C.
            Operating
                Expenses and Related Party
                Waivers




Operating
      expenses are deducted daily from the income earned by the Down-MACRO Holding
      Trust (and, if income is insufficient during any quarter, from the assets of
      the
      Down-MACRO Holding Trust) in an amount equal to the product of the trust's
      assets, including Treasuries and cash (but excluding the value of the settlement
      contracts and the income distribution agreement) held by the Down-MACRO Holding
      Trust on each day (the “ **Down-MACRO
      Asset Amount** ”)
      and
      (i) a rate of 160 basis points per annum until the second anniversary of the
      formation of the Down-MACRO Holding Trust and (ii) a rate of 150
      basis

      with
      respect to the services for the Down-MACRO Holding Trust an amount equal to
      the
      product of a per annum rate of 0.08% and the Down-MACRO Asset Amount on such

Investors
      Bank & Trust Company is the “ **Custodian** ”

D.
            Distributions





The
      Trustee of the Down-MACRO Holding Trust will make quarterly and final
      distributions to each person who was a “ **Registered
      Owner,** ”
which
      is the depository or nominee thereof in which name the Down-MACRO Holding Shares
      are registered, on the record date that preceded such distribution date. The
      quarterly and final distributions will be made after all expenses of the
      Down-MACRO Holding Trust have been made. The amount of the quarterly
      distributions may consist of interest and other income received on the debt
      securities issued by the U.S. government and repos, income received by the
      Down-MACRO Holding Trust under the Income Distribution Agreement, and all
      paid-in interest associated with any paired issuances. For the quarters ended
      June 30, 2007 and March 31, 2007, the distributions were approximately $0.4431
      per share and $0.5259 per share, respectively. For the period ended December
      31,
      2006, the distribution was approximately $0.1488 per share.

E.
            Share
                Transactions





For
      the
      six-months ended June 30, 2007, 250,000 of the Down-Macro Holding Trust shares
      were created at the value of the equity attributable to such units of
      $14,236,865, with an underlying value of $15,401,500. The Down-MACRO Holding
      Trust receives, for each share issued, cash equal to the Starting Level ($60)
      and the equalization amount. The increase/decrease in the contractual value
      of
      the settlement contracts resulting from creations results in the net increase
      in
      net assets per share on creations being equal to underlying value per share
      on
      the date of issuance. Similarly, the increase/decrease in the fair value of
      the
      settlement contracts from creations results in the net increase in net assets
      from creations for financial reporting purposes being equal to equity
      attributable to such shares on the date of issuance. Accordingly, such
      increase/decrease in fair value is included as part of the
      contributions/redemptions in the Statement of changes in Shareholders’ Equity.
      For the six-months ended June 30, 2007, 450,000 of Down-MACRO Holding Trust
      shares were redeemed at the value of the equity attributable to such shares
      of
      $26,408,713, with an underlying value of $28,734,000.





F.
            Indemnifications




Under
      the
      Down-MACRO Holding Trust's organizational documents, the Depositor, the
      Administrative Agent, the Trustee, NYMEX and MacroMarkets LLC are indemnified
      by
      the Down-MACRO Holding Trust against any liability or expense that any of them
      may incur in connection with the service and licensing agreements into which
      they entered with the Down-MACRO Holding Trust that is not the result of gross
      negligence, bad faith, willful misconduct or reckless disregard on their part.
      The Down-MACRO Holding Trust's maximum exposure under these indemnification
      arrangements (as set forth in their respective trust agreements and certain
      licensing agreements) is unknown and dependent upon future claims that may
      be
      made against the Down-MACRO Holding Trust based on events that have not yet
      occurred. However, the Down-MACRO Holding Trust expects the risk of loss to
      be
      remote.

On
      September 15, 2006, the Financial Accounting Standards Board (“FASB”) issued
      Statement of Financial Accounting Standards No. 157, “Fair Value Measurements”
(“ **SFAS
      No. 157** ”).
      SFAS
      No. 157 defines fair value, establishes a framework for measuring fair value
      in
      accordance with generally accepted accounting principles and expands disclosure
      about fair value measurements.  SFAS No. 157 is effective for fiscal years
      beginning after November 15, 2007.  The Depositor of the Down-MACRO
      Tradeable Trust is currently evaluating the impact the adoption of SFAS No.
      157
      will have on the Down-MACRO Tradeable Trust’s financial statement
      disclosures.





On
      June
      18, 2007, the American Institute of Certified Public Accountants’ (AICPA)
      Accounting Standards Executive Committee (AcSEC) issued Statement of Position
      (SOP) 07-1, “Clarification of the Scope of the Audit and Accounting Guide”
Investment Companies and “Accounting by parent Companies and equity Method
      Investors for Investments in Investment Companies.” The SOP provides guidance
      for determining whether an entity is within the scope of the AICPA Audit and
      Accounting Guide for Investment Companies (the Guide). For those entities that
      are investment companies under the SOP, it also addresses whether the
      specialized industry accounting principles of the Guide should be retained
      by a
      parent company in consolidation or by an investor that has the ability to
      exercise significant influence over the investment company and applies the
      equity method of accounting to its investment in the entity (referred to as
      an
      equity method investor). In addition, the SOP includes certain disclosure
      requirements for parent companies and equity method investors in investment
      companies that retain Investment Company accounting in the parent company’s
      consolidated financial statements or the financial statements of an equity
      method investor. SOP 07-1 is effective for fiscal years beginning on or after
      December 15, 2007. The Depositor of the Down-MACRO Holding Trust is currently
      evaluating the scope of SOP 07-1 and the impact it will have on the Down-MACRO
      Holding Trust’s financial statement disclosures.

H.
            Concentration
                Risk




The
      Down-MACRO Holding Trust's performance at underlying value is determined by the
      daily
      Closing Price of NYMEX
      light sweet crude oil futures
      contracts .
      Therefore, the primary risk of loss to the Down-MACRO Holding Trust comes from
      fluctuations in the Closing Price of c rude o il futures
      contracts. The minimum price level of crude oil futures for which the Down-MACRO
      Holding Trust can deliver investment returns at underlying value corresponding
      inversely to the change in price of such crude oil futures is equal to $0.00.
      (Conversely, the maximum price level of crude oil futures for which the Up-MACRO
      Holding Trust can deliver investment returns at underlying value corresponding
      to the change in price of such crude oil futures is equal to twice the Starting
      Level $120.) Also, the Down-MACRO Holding Trust is exposed to possible
      indemnification obligations, as described above. An additional risk comes from
      interest rate fluctuations, which affects the total amount of income earned
      by
      the Paired Holding Trusts. In addition, Investors Bank & Trust holds 100% of
      the cash and cash equivalents on deposit. There are risks in terms of exposure
      to Investors Bank & Trust in that the Down-MACRO Holding Trust may
      potentially lose all or a portion the cash that is held at Investors Bank &
Trust.





I.
            Termination
                of the Trust





The
      Down-MACRO Holding Trust will be terminated in December of 2026. On such
      date , the
      holders of any Down-MACRO Holding Shares which remain outstanding will receive
      the net assets of the Down-MACRO Holding Trust after the settlement and
      termination of all outstanding Settlement Contracts in
      the
      same manner as such contracts would be settled and terminated in connection
      with
      any Paired Optional Redemption. The Income Distribution Agreement will also
      be
      terminated on this date ,
      but no
      settlement obligations will be due thereunder.




Additional
      termination events of the Down-MACRO Holding Trust consist of (i) any event
      in
      which any of the Paired Holding Trusts or the Tradeable Trusts (collectively,
      the “ **MACRO**  **Trusts** ”)
      become
      insolvent or bankrupt; (ii) any of the MACRO Trusts become required to register
      as “investment companies” under the Investment Company Act of 1940, as amended;
      (iii) the MACRO Trusts are prohibited from using, or NYMEX or the applicable
      substitute oil price provider does not establish, a settlement price for light
      sweet crude oil futures or the applicable substitute reference oil price for
      five consecutive New York Business Days and no other substitute oil benchmark
      is
      identified and approved by the shareholders and/or the Depositor is unable
      to
      negotiate a licensing arrangement with any such substitute oil price provider;
      (iv) the Closing Price falls to only 15% of its Starting Level (at which Closing
      Price the Down-MACRO Holding Trust would be entitled to receive all but 15%
      of
      the Up-MACRO Holding Trust’s assets) or the Closing Price rises to a level that
      is equal to 185% of its Starting Level (at which Closing Price the Down-MACRO
      Holding Trust would be entitled to retain only 15% of its own assets under
      the
      Settlement Contracts); (v) the reduction of the funds of either of the Paired
      Holding Trusts to an amount below $10 million U.S. dollars; and (vi) the amount
      of cash and U.S. government securities on deposit in the Up-MACRO Holding Trust
      or the Down-MACRO Holding Trust is reduced to $50 million U.S. dollars or less
      after previously reaching an amount equal to $200 million U.S. dollars or more,
      or the failure on the part of the Paired Holding Trusts to each hold cash and
      U.S. government securities in an amount equal to at least $200 million U.S.
      dollars after six months or more have elapsed since the commencement of
      operations and the Depositor elects to terminate the Paired Holding Trusts.
      As
      of May 29, 2007, six months had elapsed since the commencement of operations
      of
      the Paired Holding Trusts and they held approximately $48.3 million of cash
      and
      government securities. Therefore, because the Paired Holding Trusts have failed
      to each hold cash and U.S. government securities in an amount equal to at least
      $200 million U.S. dollars, after six months have elapsed since the Closing
      Date,
      the Depositor has the right, for so long as such $200 million U.S. dollars
      threshold has not been reached, to terminate each of the Paired Holding Trusts.
      However, the Depositor currently has no intention of terminating the Paired
      Holding Trusts.





In
      the
      case of each of these termination events, including the event described in
      clause (iv) above, the Settlement Contracts would settle on the next
      distribution date on the basis of the Closing Price on the last New York
      Business Day that preceded that distribution date, which may be different from
      the Closing Price at the time when the termination event occurred.

      July

        Holding
        Shares, assuming all of Claymore Securities, Inc.'s duties as marketing agent
        and (B) will resign as an administrative agent for the Down-MACRO Holding
        Trust,
        effective September 30, 2007, after a successor administrative agent is
        appointed and accepts such appointment in accordance with the terms of the
        Claymore MACROshares Oil Down Holding Trust Agreement and (ii) Claymore Group
        Inc. will sell its equity interest in MACRO Securities Depositor, LLC to
        MacroMarkets LLC by August 18, 2007 and the Claymore MACROshares Oil Down
        Holding Trust and Claymore MACROshares Oil Down Holding Shares will be renamed

      financial statements and accompanying notes filed as part of this
      report.*





**INTRODUCTION**





***Overview
      of the Trust’s Structure***





The
      assets of the Down-MACRO holding trust consist of an income distribution
      agreement and settlement contracts entered into with the Up-MACRO holding trust.
      The Down-MACRO holding trust also holds U.S. Treasuries and repurchase
      agreements on U.S. Treasuries to secure its obligations under the income
      distribution agreement and the settlement contracts. The Down-MACRO holding
      trust makes quarterly distributions of its net income and a final distribution
      of all assets it holds on deposit on the final scheduled termination date,
      an
      early termination date or a redemption date. Each quarterly and final
      distribution will take into consideration the settlement price of NYMEX light
      sweet crude oil futures contracts of a designated maturity, as established
      and
      reported by NYMEX on each price determination day (such price, the "Applicable
      Reference Price of Crude Oil"). The starting level for the Applicable Reference
      Price of Crude Oil for purposes of distributions on the Down-MACRO tradeable
      shares is $60.00. The obligations under the settlement contracts on the final
      scheduled termination date, an early termination date or a redemption date
      are
      determined based on the Applicable Reference Price of Crude Oil on the last
      preceding price determination day and the percentage change of such price from
      the starting level.





The
      Down-MACRO holding trust issues and offers Down-MACRO holding shares on a
      continuous basis at their underlying value. Each new issuance is made at the
      request of authorized participants in the form of MACRO units consisting of
      pairs of 50,000 Down-MACRO holding shares and 50,000 Up-MACRO holding shares
      contemporaneously issued by the Up-MACRO holding trust.





The
      Down-MACRO holding trust distributes quarterly to its shareholders the net
      income from the Treasuries it holds on deposit during such quarter plus or
      minus, in accordance with the income distribution agreement, amount received
      from or paid to, as applicable, the Up-MACRO holding trust. Final distributions
      are made to shareholders on the earlier of the final scheduled termination
      date
      and an early termination date. Down-MACRO holding shares may be exchanged at
      any
      time by authorized participants for the Down-MACRO tradeable shares on a
      one-to-one basis in minimum lots of 50,000 shares.





***Daily
      Reporting***





The
      American Stock Exchange or the “AMEX” acts as a calculation agent for the
      Down-MACRO holding trust, the Down-MACRO tradeable trust, the Up-MACRO holding
      trust and the Up-MACRO tradeable trust. Throughout each price determination
      day
      (as defined in the prospectus), from the opening of trading on NYMEX to the
      close of trading of the tradeable shares on the AMEX, the AMEX calculates and
      posts every fifteen seconds to the consolidated tape and on its website located
      at http://www.amex.com/amextrader, immediately following each transmission
      from
      NYMEX of the current market price of the light sweet crude oil futures contract
      of the designated maturity, an indicative per share underlying value of one
      Down-MACRO holding share and one Down-MACRO tradeable share. At the end of
      each
      price determination day, the AMEX also calculates the premium or discount of
      the
      mid-point of the bid/offer for the Down-MACRO tradeable shares on the AMEX
      to
      the per share underlying value of those shares for such price determination
      day
      that is calculated and provided to the AMEX by the trustee.

***Per-Share
      Underlying Value of MACRO Holding Shares Relative***


***to
      the Applicable Reference Price of Crude Oil***





For
      the
      period from April 1, 2007 to June 30, 2007, the per-share underlying value
      of
      the Down-MACRO holding shares tracked the inverse of the Applicable Reference
      Price of Crude Oil by an average daily price differential of $0.23 (0.43% of
      the
      trust's underlying value). The differential ranged from approximately $0.01
      to
      approximately $0.45 and increased throughout the period leading up to the
      ex-dividend date of June 27, 2007, at which time the differential between the
      per-share underlying value of the Down-MACRO holding shares and the inverse
      of
      the Applicable Reference Price of Crude Oil reverted to approximately $0.01.
      Exhibit 1a illustrates the differential between the per-share underlying value
      of the Down-MACRO holding shares and the inverse of the Applicable Reference
      Price of Crude Oil for the period from April 1, 2007 to June 30,
      2007.





Exhibit
      1a








The
      differential between the per-share underlying value of the Down-MACRO holding
      shares and the inverse of the Applicable Reference Price of Crude Oil can be
      attributed to accrued interest on Treasuries held by the Down-MACRO holding
      trust, after accruing for the fees and expenses incurred by the Down-MACRO
      holding trust. Exhibit 1b compares the per-share underlying value of the
      Down-MACRO holding shares relative to the Applicable Reference Price of Crude
      Oil for the period from April 1, 2007 to June 30, 2007.

Exhibit
      1b





For
      the
      period April
      1,
      2007 to June 30, 2007, the underlying value of the Up-MACRO holding shares
      tracked the Applicable Reference Price of Crude Oil by an average daily price
      differential of $0.27 (0.41% of UCR’s underlying value). The differential ranged
      from approximately $0.01 to approximately $0.53 and increased throughout the
      period leading up to the ex-dividend date of June 27, 2007, at which time the
      differential between the per-share underlying value of the Up-MACRO tradeable
      shares and the Applicable Reference Price of Crude Oil reverted to approximately
      $0.01. Exhibit 1c illustrates the differential between the per-share underlying
      value of the Up-MACRO tradeable shares and the Applicable Reference Price of
      Crude Oil for the period from April 1, 2007 to June 30, 2007.





14




Exhibit
      1c





The
      differential between the per-share underlying value of the Up-MACRO holding
      shares and the Applicable Reference Price of Crude Oil can be attributed to
      accrued interest on Treasuries held by the Up-MACRO holding trust, after
      accruing for the fees and expenses incurred by the Up-MACRO holding trust.
      Exhibit 1d compares the per-share underlying value of the Up-MACRO tradeable
      shares relative to the Applicable Reference Price of Crude Oil for the period
      from April 1, 2007 to June 30, 2007.

Exhibit
      1d








The
      Down-MACRO holding shares are not listed on any securities exchange or public
      trading market. The Down-MACRO holding shares may only be held by qualified
      institutional buyers (as defined in Rule 144A under the Securities Act),
      authorized participants (as defined in the prospectus), and the Down MACRO
      tradeable trust.





As
      of
      June 30, 2007, all of the outstanding Down-MACRO holding shares are held by
      the
      Down-MACRO tradeable trust. Because there is no established public trading
      market for the Down-MACRO holding shares, high and low sales prices and bid
      information are unavailable. The following table sets forth, for the period
      indicated, the high and low per share underlying values (as defined in the
      prospectus) for the Down-MACRO holding shares.

**Review
      of Financial Results**





Results
      of Operations





On
      November 29, 2006, the Down-MACRO holding trust established its starting level
      at $60.00 per share and issued 200,000 shares to the initial authorized
      purchaser, KV Execution Services LLC, in exchange for $12,000,000 in cash.
      Such
      shares were issued at their initial underlying value of $57.55 per share. Since
      this date, the Down-MACRO holding trust's underlying value grew from
      approximately $11,500,000 at November 29, 2006, to approximately $17,268,000
      at
      June 30, 2007. The increase in underlying value resulted primarily from an
      increase in outstanding shares, which rose from 200,000 at November 29, 2006
      to
      350,000 at June 30, 2007 due to 600,000 shares (12 units) being created and
      450,000 shares (9 units) being redeemed during the period, of which 100,000
      shares (2 units) were created in exchange for a deposit of approximately
      $5,492,500 at the applicable underlying value and 50,000 shares (1 unit) were
      redeemed in exchange for a withdrawal of approximately $2,720,000 at the
      applicable underlying value during the three months ended June 30, 2007. Each
      unit consists of 50,000 shares.

The
      Trust
      generated net investment income of nearly $166,000 during the quarter ended
      June
      30, 2007 as a result of its investment in repurchase agreements and U.S.
      Treasury obligations. Additionally, as the valuation of the settlement contract
      increased during the period, as discussed below, the Trust generated
      approximately $1.1 million of realized and unrealized losses on the settlement
      contracts and income distribution agreement.





*Liquidity*


To
      the extent of management's knowledge, there are no trends or demands,
      commitments, events, or uncertainties that will result in, or that that are
      reasonably likely to result in, the registrant's liquidity increasing or
      decreasing in any material way. The main obligations of each of the Up-MACRO
      holding trust and Down-MACRO holding trust are its obligations, if any, pursuant
      to the income distribution agreement and settlement contracts. The Up-MACRO
      holding trust and Down-MACRO holding trust hold U.S. Treasuries and repurchase
      agreements on U.S. Treasuries to secure each of its obligations under the income
      distribution agreement and the settlement contracts.

*Valuation
      method of the Settlement Contracts and the Income Distribution Agreement*





For
      the
      purpose of financial reporting, the settlement contracts and income distribution
      agreement constitute derivative contracts. Accordingly, these derivative
      contracts are recorded in the financial statements at fair value, as determined
      by the Administrative Agent. As there is no market for these derivative
      contracts, and no such market is expected to develop, the Administrative Agent
      determines the fair value of these derivative contracts by reference to various
      inputs. These inputs include the contractual amount due to or from the other
      trust, applicable market indices, and the prices of transactions in Down-MACRO
      Tradeable Shares on the American Stock Exchange. For most of the reporting
      period, the fair value of these derivative contracts more closely followed
      the
      18-month NYMEX futures contract as opposed to their contractual value. At period
      end, the Administrative Agent determined, based upon various inputs the most
      significant of which was transactions for the Down-MACRO Tradeable Shares in
      the
      open market, that fair valuation for these derivative contracts was more
      appropriately based upon the 18-month NYMEX futures contract.





As
      a
      result, the per share value on June 30, 2007, for financial reporting purposes,
      based upon the fair valuation determination of the Administrative Agent, was
      $47.44. The per share Underlying Value for the same day was $49.34. The
      Administrative Agent will continue to evaluate the fair value of these
      derivative contracts for each financial reporting period.





*Off-Balance
      Sheet Arrangements*





The
      Down-MACRO holding trust is not a party to any off-balance sheet
      arrangements.

      Agreement does not authorize the trustee to borrow for payment of the Down-MACRO

      to any foreign currency related market risk. The Down-MACRO holding trust does
