u.s. repo financial

"overnight funding costs in U.S. repo markets."

A U.S. repo (repurchase agreement) is a very short-term, collateralized loan in which one party sells government or other high-quality securities and agrees to buy them back at a slightly higher price, often the next day. Think of it like a secured overnight loan or a pawn-shop arrangement for securities; it lets banks, funds and dealers borrow cash or lend spare cash safely. Repo rates and volumes matter to investors because they influence short-term interest costs, market liquidity, margin financing and the stability of money markets.

central limit order book technical

"BrokerTec's dealer-to-dealer central limit order book (CLOB) platform"

A central limit order book is a continuously updated electronic list that shows buy and sell orders for a stock in one place, sorted by price and time. Think of it as a public marketplace bulletin board where the highest offers to buy and the lowest offers to sell meet and get matched; it matters to investors because it determines real-time price formation, liquidity, and how quickly large trades can be executed without moving the market.

clob technical

"dealer-to-dealer central limit order book (CLOB) platform"

A CLOB (Central Limit Order Book) is an electronic trading system that openly lists buy and sell orders by price and time and automatically matches trades when prices agree. Think of it like a transparent ticket line where everyone’s offers and wants are visible, so you can see how many buyers or sellers are waiting and at what prices. For investors, a CLOB matters because it improves price discovery, shows real liquidity, and helps predict how easily and cheaply an order will execute.

volume-weighted median technical

"RFR USD uses a volume-weighted median methodology—the same standard used"

The volume-weighted median is the price point at which half of the total trading volume for a security occurred at lower prices and half at higher prices, giving larger trades more influence than smaller ones. For investors it highlights the price level where the bulk of market activity happened, acting like a midpoint you’d get if you sorted trades by price and counted through them by size — often a more robust indicator of market interest than a simple average.

sofr financial

"same standard used by the New York Federal Reserve in the calculation of SOFR."

The Secured Overnight Financing Rate (SOFR) is a market benchmark that measures the cost of borrowing cash overnight using U.S. Treasury securities as collateral. Investors watch SOFR because it acts like a speedometer for short-term interest costs—affecting loan rates, bond yields and the pricing of interest-rate contracts—so movements change borrowing expenses, cash returns and the value of interest-sensitive investments.

otc derivatives financial

"licensed for use in derived products such as OTC derivatives, structured products"

Over‑the‑counter (OTC) derivatives are private financial contracts—like swaps, forwards or options—made directly between two parties instead of through a public exchange. They matter to investors because these deals are highly customizable (like tailoring a suit) but carry greater credit and liquidity risk: the other party might not perform and it can be hard to sell the contract, so OTC positions can amplify gains or losses and affect a firm’s financial health.

floating rate notes financial

"structured products and floating rate notes."

Floating rate notes are debt securities that pay interest that adjusts periodically based on a short-term interest benchmark (for example, LIBOR or SOFR), so the cash interest you receive goes up or down with market rates. For investors they act like an adjustable-rate loan: they help protect income when overall interest rates rise and generally lose less value than fixed-rate bonds when rates move, making them useful for managing interest-rate risk.

central counterparty clearing financial

"operates one of the world's leading central counterparty clearing providers"

A central counterparty clearing (CCP) is a specialized financial intermediary that sits between buyers and sellers of securities or derivatives, becoming the buyer to every seller and the seller to every buyer to guarantee trades are completed. Like an insurance-backed referee, it manages the risk of someone failing to pay by requiring collateral, pooling resources, and simplifying many trades into smaller net payments, which helps investors by lowering the chance of loss from a counterparty default and improving market stability and liquidity.

- The U.S. Dollar RepoFunds Rate provides a one-day, risk-free rate based on centrally cleared U.S. repo trades transacted on BrokerTec 

CHICAGO, May 6, 2026 /PRNewswire/ -- CME Group, the world's leading derivatives marketplace, today announced it has launched the U.S. dollar RepoFunds Rate (RFR USD) to provide a robust measure of overnight funding costs in U.S. repo markets.

The new benchmark uses data from centrally cleared overnight U.S. repo trades executed on BrokerTec's dealer-to-dealer central limit order book (CLOB) platform, which saw average daily trading volumes of $412 billion in March. RFR USD provides the market with same-day U.S. repo price transparency, with the end-of-day benchmark published at 3:00 p.m. ET, providing an early indicator of market activity, ahead of the T+1 daily publication of SOFR rates.

"BrokerTec's U.S. repo market is a definitive source of price discovery for U.S. Treasury repo," said Matt Gierke, Global Head of BrokerTec. "This new RFR USD benchmark provides enhanced transparency, enabling precise mark-to-market insights for dealers and improved access to valuation data for the broader marketplace." 

"Our benchmarks are calculated using data from highly liquid markets to provide transparent, robust and reliable reference rates," says Max Ruscher, Head of Benchmark Services, CME Group. "RFR USD is the latest expansion to the existing suite of RFR products which measure the cost of secured one day funding in the euro, sterling and yen sovereign bond markets and are increasingly used as reference rates in the OTC swap market."

Administered by CME Group Benchmark Administration, RFR USD uses a volume-weighted median methodology—the same standard used by the New York Federal Reserve in the calculation of SOFR. It is available via CME Datamine and can be accessed by BrokerTec CLOB clients. The rates are also licensed for use in derived products such as OTC derivatives, structured products and floating rate notes.
