The One Question Holding Up US Crypto Law: Should Your Stablecoins Pay Interest?

Senator Cynthia Lummis says the US market structure bill is almost done. "We are so close this time." One issue remains: whether stablecoins can pay yield. That single question could determine whether stablecoins become America's next savings account or stay confined to crypto trading desks.

The Fight Over Yield

The CLARITY Act passed the House in July 2025. The Senate version has been stuck since January, when Banking Committee chair Tim Scott indefinitely postponed a markup. According to Cointelegraph, Lummis identified "the fight over stablecoin yield and rewards" as "the main thing" blocking progress. The DeFi provision? Resolved. Money transmitter definitions? Settled. Yield is the last wall.

Scott expected a formal yield proposal "before the end of this week." An April markup is planned after Easter recess. Senator Bernie Moreno issued a blunter deadline: "If we don't get the CLARITY Act passed by May, digital asset legislation will not pass for the foreseeable future."

Why Banks Are Terrified of Stablecoin Yield

Here's the math that keeps bank lobbyists up at night. The average US savings account pays 0.45% APY. High-yield savings accounts hover around 4.5%. Now imagine Circle or Tether offering 4-5% yield on USDC or USDT — no minimum balance, instant access, no branch visit required.

If even a small fraction of US savings deposits migrated to yield-bearing stablecoins, hundreds of billions could leave the banking system. Banks use those deposits to fund mortgages, car loans, and business credit. A deposit exodus doesn't just hurt bank profits — it constrains lending across the entire economy. That's the argument banks are making to Congress, and it's not entirely wrong.

The Crypto Side's Counter

Crypto advocates argue stablecoin lending is just... lending. Banks take deposits and lend them out. Stablecoin issuers invest reserves (mostly in T-bills) and could pass some yield to holders. Both are intermediation. The difference is regulatory treatment: banks have FDIC insurance, capital requirements, and stress tests. Stablecoins have none of that — yet.

The White House has held three meetings in 2026 with both sides trying to broker a compromise. The likely outcome: stablecoins can offer yield, but only under new reserve and disclosure requirements that mimic some banking safeguards without requiring a full bank charter.

What This Means for Your Stablecoins

If yield is permitted, expect a rapid product launch from every major issuer. Circle has been positioning USDC as a "regulated digital dollar" for exactly this moment. Tether just hired a Big Four auditor. Both are building compliance infrastructure to offer yield the day the law allows it.

If yield is blocked, stablecoins remain payment instruments — useful for transfers and trading, but not for savings. The multi-trillion-dollar deposit market stays with banks.

Moreno's May deadline isn't arbitrary. Congressional attention is finite, and the 2026 midterm cycle is already consuming legislative bandwidth. If this window closes, stablecoin yield could be off the table for years.
