Banks lobby senators against stablecoin yield rule

TLDR

US banks are aggressively pressuring senators to weaken or kill a proposed rule that restricts yield on stablecoin holdings in the CLARITY Act.

1. Banking trade groups are running a coordinated call campaign against a stablecoin yield compromise negotiated with crypto industry advocates.
2. The fight over whether stablecoins can pay interest-like returns is now the main obstacle to moving the CLARITY Act through the Senate.
3. The outcome will shape whether regulated dollar stablecoins in the US can offer yield to users or become low-yield payment rails dominated by banks.

Deep Dive

1. What Banks Are Fighting

The CLARITY Act includes a stablecoin section that limits platforms from paying yield on stablecoin balances in ways that resemble bank deposits. A recent draft reportedly bans yield offered directly or indirectly or in forms that are economically or functionally equivalent to interest on stablecoins.

Senators Thom Tillis and Angela Alsobrooks reached a compromise that would ban passive interest on idle balances but still allow activity-based rewards, such as incentives tied to payments or usage rather than simple holding. Banking groups, led by organizations like the North Carolina Bankers Association, have responded with a direct lobbying blitz, urging member banks to call Senate offices, particularly Tillis, to oppose this yield language and reopen negotiations. Reports say banks warn of up to $6.6 trillion in potential deposit flight if yield-bearing stablecoins compete with bank accounts, though White House economists have argued that banning stablecoin yield would barely lift bank lending while imposing an estimated $800 million net welfare cost on consumers.

2. How Lobbying Threatens The CLARITY Act

This pressure campaign has already pushed the Senate Banking Committees markup of the CLARITY Act from April into at least May, squeezing the legislative calendar before the Memorial Day recess. Senator Bernie Moreno has described the end of May as roughly the last realistic window to pass a comprehensive US crypto market structure law in this cycle, with prediction markets now assigning less than a 50 percent chance the bill becomes law in 2026.

Crypto industry groups, including over 100 organizations, have sent letters urging Senate leaders to move the bill despite bank objections, warning that delays are pushing capital and innovation toward jurisdictions like the EU, Dubai and Singapore that already have clearer rules.

3. What It Means For Stablecoins And Users

If banks prevail and a strict yield ban survives, most US regulated platforms may be unable to offer meaningful yield on stablecoin balances, pushing users toward offshore venues, experimental DeFi structures, or non US compliant products to earn returns.

At the same time, traditional institutions are positioning to capture stablecoin economics on the back end. Morgan Stanleys newly launched Stablecoin Reserves Portfolio MSNXX, a money market fund designed for stablecoin issuers, aligns with federal reserve requirements and lets issuers earn institutional yields on reserves while end users may be capped on what they receive.

Conclusion

Bank lobbying against the stablecoin yield rule has turned a narrow technical issue into the main blocker for the CLARITY Act, delaying what could be the United States last near term chance at comprehensive crypto market structure legislation. How senators resolve this fight will determine whether US stablecoins function as low yield payments tools that primarily benefit banks and issuers, or as regulated, yield bearing instruments that share more of the economics with users while keeping activity inside the US regulatory perimeter.
