8.1 Discussion: Contracts Not Readily Susceptible to Manipulation

The interest rate swap (IRS) market is considered the largest derivative market in the world,

with an estimated &#" trillion in notional principal outstanding as of June "*"" according to

the Bank for International Settlements.

"(

IRS are cash-settled, so there is no deliverable supply to be manipulated. IRS are widely used

by corporations, insurance companies, banks, and governments to transfer and manage interest

rate risk. Interest-rate-linked financial instruments (e.g., bonds, loans, government interestbearing instruments, and interest-rate-sensitive instruments) are not easily susceptible to manipulation because of the size and liquidity of the cash market for such instruments. Furthermore, IRS-associated interest rate futures contracts, loans, cleared swaps, and cash and futures

markets for government debt securities offer a deep liquidity pool to hedge and risk-manage

swaps based on such rates indexes.

RTX SEF will monitor trading in these swaps. RTX SEF has a comprehensive surveillance

program and rules to prevent RTX SEF Participants from engaging in manipulative activity

and possesses discretion to impose fines and disciplinary sanctions on its Participants.

8.1.1 Discussion of Index Reference Prices: BSBY & SOFR

RTX SEF limits the indexes underlying its interest rate swap offerings to well-established,

publicly available third-party interest rate market benchmarks. Some are published by central

banks (such as the United States Federal Reserve Secured Overnight Financing Rate (SOFR)

rate), while others are calculated and published by reliable independent providers (such as trade

associations, exchanges, or other third parties). The interest rate reference prices underlying

swaps on RTX SEF are the timeliest, most widely recognized, and reliable benchmarks for interest rates in their respective markets. The index levels are readily available and commercially

acceptable as benchmarks for borrowers, lenders, investors, portfolio managers, governments,

and public policy makers.

The New York Federal Reserve Bank describes the SOFR as a broad measure of the cost of

borrowing cash overnight collateralized by Treasury securities. The SOFR includes all trades

in the Broad General Collateral Rate") plus bilateral Treasury repurchase agreement (repo)

transactions cleared through the Delivery-versus-Payment (DVP) service offered by the Fixed

Income Clearing Corporation (FICC), which is filtered to remove a portion of transactions

considered “specials.”

$#
( BASIS SWAP—USD BSBY VS. SOFR

SOFR was identified by the Alternative Reference Rates Committee (ARRC)

#* as its recommended alternative to U.S. dollar LIBOR for use in certain new U.S. dollar derivatives and

other financial contracts.

#! The New York Fed began publication of the SOFR on April #,

"*!(. In the production of the Treasury SOFR repo reference rates, the New York Fed has

endeavored to adopt policies and procedures consistent with best practices for financial benchmarks, including the IOSCO Principles for Financial Benchmarks.

#"

BSBY is a proprietary index calculated daily and published at (:** a.m. ET on each U.S. business day by Bloomberg Index Services Limited (BISL), Bloomberg’s authorized benchmark

administrator. BSBY provides a series of credit sensitive reference rates that incorporate bank

credit spreads and defines a forward term structure. BSBY also seeks to measure the average

yields at which large global banks access USD senior unsecured marginal wholesale funding.

BSBY uses an advanced curve-fitting methodology to calculate overnight, !-month, #-month,

&-month, and !"-month yields. The index is based on aggregated anonymized data anchored

in transactions and executable quotes sourced from Bloomberg’s electronic trading solutions

and trades of short-term senior unsecured bank corporate bonds reported by FINRA. BSBY

is based on transactions of instruments used by banks to fund themselves, includes a systemic

credit spread in its rate, and can be used as a supplement to SOFR in the lending market. The

BSBY methodology has several protections against manipulation: the weight of each transaction is capped at $%** million to help ensure stability and reduce the risk of the rate being

unduly influenced by any single data point; there is a single issuer cap of "*% to ensure any

given BSBY tenor is an average rate across an appropriately broad sample; all yields above

the '%th volume percentile and below the "%th volume percentile are eliminated from the final calculation. BISL provides robust governance and oversight over its benchmark offerings.

BSBY’s transaction-based inputs, robust construction, and resilient methodology are designed

to meet the high standards of both the BMR and the IOSCO principles for financial benchmarks (IOSCO Principles). BISL confirmed BSBY adheres to the IOSCO Principles

## and an

independent assurance report is available.

#$

RTX SEF believes that the large number of participants in each market and the calculation

of each index by well-known, independent third parties further limits the susceptibility of

manipulation of these indexes. RTX SEF believes that such benchmark indexes (many of which

also underlie liquid interest rate futures contracts on major Designated Contract Markets) are

not readily susceptible to manipulation due to the large number of index participants, ubiquity,

and broad-market nature.
