Tradeweb Markets Inc. (NASDAQ: TW) announced the addition of algorithmic execution strategies from Citi and RBC Capital Markets to its dealer algorithmic execution offering for U.S. Treasuries.

The expansion builds on Tradeweb's launch of dealer algorithmic execution capabilities for U.S. Treasuries in the previous year. The platform allows institutional investors to execute orders over defined time periods with dealer liquidity providers.

Tradeweb's U.S. government bond marketplace processed an average daily volume of $237.2 billion in 2025, representing an 11.6% increase year-over-year, according to the company's statement. The platform provides access to liquidity from 38 providers and supports trading in Treasury bills, notes, nominal bonds, basis, floating rate notes, STRIPS and TIPS.

The marketplace offers multiple trading protocols including Request-for-Quote, List Trading, Executable Streams and Request-for-Market capabilities. Tradeweb plans to continue expanding its dealer algorithmic network by adding additional global dealers.

Citi's participation includes streaming firm, multi-level prices on the platform alongside its algorithmic strategies. RBC Capital Markets described itself as an early participant in the U.S. Treasuries algorithm space.

The algorithmic execution tools complement Tradeweb's existing electronic trading ecosystem, which includes cash and futures spread execution capabilities. Tradeweb serves more than 3,000 clients across more than 85 countries and facilitated more than $2.6 trillion in average daily notional value over the past four fiscal quarters.
