Senate Lets Clarity Act Stall, Stablecoin Rewards Remain
The U.S. Senate blocked an effort to limit stablecoin rewards, while the GENIUS Act and the role of Circle and Coinbase keep the debate over interest on USDC open.
Key Takeaways
- The U.S. Senate did not advance the Clarity Act on September 15, 2026, leaving restrictions on stablecoin rewards off the table for now.
- The GENIUS Act bans issuers from paying interest or yield on payment stablecoins starting January 18, 2027, unless regulators set final rules earlier.
- Circle and Coinbase earn money from USDC reserves, while the market reacted mixed to the bill's failure.
The U.S. Senate did not advance the Clarity Act on September 15, 2026. That left an effort to rein in rewards on stablecoins on hold, while the debate over interest on dollar-pegged tokens remains open for now. For USDC users on Coinbase and issuer Circle, nothing changes right now, but the broader fight with banks and regulators is far from over.
What the Bill Was Supposed to Do
The Clarity Act was meant to draw a line between interest paid directly by an issuer and rewards that come from trading or other activity. That difference mattered a lot for crypto platforms, because stablecoin rewards often feel like interest on a savings account in practice. Banks saw that as a risk, since products like that can pull deposits away from regular checking accounts.
That tension has been around for a while. The GENIUS Act, which was signed in July 2025, bans issuers of payment stablecoins from paying interest or yield directly to holders. That law is set to take effect on January 18, 2027, or 120 days after final rules from federal regulators. The failed vote on the Clarity Act does not change that for now.
Circle and Coinbase Feel the Pressure
The debate is not just about legal text, but also about money flows. According to 247 Wall St., the rewards come from reserves backing USDC, which are invested in things like U.S. Treasury bills and repurchase agreements. In the second quarter of 2026, Circle reported an average USDC circulation of $76.5 billion and $668 million in reserve income. Coinbase earned $292 million from stablecoins in that same period, about a quarter of its total revenue.
The interest-rate environment also matters. The Federal Reserve set the top end of its interest rate at 4.00 percent on September 16, while short-term Treasury bills were yielding between 3.87 percent and 4.08 percent, according to the cited figures. Circle receives that return as reserve income and shares part of it with Coinbase, which then passes part of that along to users.
Why This Still Matters
For European crypto readers, this matters mainly because U.S. rules around stablecoins often set the tone for the rest of the market. If rewards on stablecoins are further restricted in the U.S., that could affect how major platforms design their products and how regulators in other markets look at similar setups. The vote also shows that the political fight between banks and crypto platforms is nowhere near over.
The market reaction was mixed. In the week of September 17, Circle fell 5.79 percent, while Coinbase rose 0.98 percent. On September 16, the day of the Fed decision, both stocks were up more than 5 percent on the session, but there was no clear relief rally after the bill stalled.
The failed vote fits into a broader U.S. debate over stablecoin rewards. Banks had already warned that incentives like these could pull deposits away, while crypto companies argue that the rules around rewards are still not final.
