Stablecoins With Yield Surge as US Lawmakers Clash

TLDR

• Yield-bearing stablecoins grew 15 times faster than the broader stablecoin market over six months.
• Circle’s USYC and Paxos’ USDG led gains with market cap increases of 198% and 169%.
• The total value of yield-bearing stablecoins reached $22.7 billion after an 11% monthly rise.
• Maple’s Syrup USDC offered the highest weekly yield at 4.54% APY, according to Messari.
• US lawmakers remain divided as the Senate delays action on the crypto market structure bill.

Yield-bearing stablecoins expanded rapidly over the past six months, according to Messari. The research firm reported that these tokens grew 15 times faster than the broader stablecoin market. However, US lawmakers remain divided over how federal law should treat crypto-linked yield.

Messari published its findings on Thursday and outlined sharp market cap increases across major tokens. The report showed that yield-bearing products attracted rising demand while the overall stablecoin market grew modestly. Meanwhile, lawmakers continue to debate provisions in pending digital asset legislation.

USYC and USDG Lead Growth in Stablecoins Segment

Circle’s USYC recorded a 198% increase in market capitalization over six months. Paxos’ Global Dollar (USDG) posted a 169% rise during the same period. Messari stated that these gains far outpaced the 9% growth in the broader stablecoin market.

The firm said the largest yield-bearing stablecoins now function like money market funds or bank deposits. “The winners don’t do payments,” Messari wrote in the report. It added that leading issuers focus on single-asset exposure rather than payment use cases.

Yield-bearing stablecoins began outpacing overall supply growth in mid-October 2025. The trend pointed to a stronger demand for blockchain-based dollar products offering yield. Stablewatch data showed the sector reached $22.7 billion after an 11% rise in 30 days.

That figure doubled the $11 billion recorded in May 2025. Still, yield-bearing tokens account for 7.4% of the $303 billion stablecoin market. The share stood at 4.5% in May last year.

USDD, USDY, and Top APYs Draw Policy Scrutiny

Tron DAO-linked Decentralized USD (USDD) rose 114% in market value over six months. Ondo Finance’s Ondo US Dollar Yield (USDY) increased 91% during the same timeframe. DefiLlama ranked Sky’s sUSDS, Ethena’s sUSDe, and Maple’s Syrup USDC among the largest by value.

Maple’s Syrup USDC offered a 4.54% annual percentage yield this week. Maple USDT followed with a 4.17% APY, while Sky Lending’s sUSDS posted 3.75%. Ethena’s USDe delivered a 3.49% APY, according to Messari data.

Lawmakers continue to debate how to regulate yield-bearing stablecoins under federal law. Senate Majority Leader John Thune said the chamber will not advance the market structure bill before April. Banking groups argue that yield features could shift deposits away from traditional banks.

The Senate Banking Committee delayed its markup in mid-January as bipartisan talks continued. President Donald Trump criticized the delay and urged faster action on the bill. The House passed the Digital Asset Market Structure Clarity Act on July 17, 2025.

The GENIUS Act became law on July 18, 2025, and it restricts interest on payment stablecoins. However, the law allows third-party platforms to offer reward programs tied to holdings. Debate over yield provisions continues as the Senate reviews the legislation.
