Over 100 Amendments Threaten CLARITY Act as Warren Targets Crypto Banking Access

The CLARITY Act aims to end years of regulatory uncertainty by assigning the CFTC oversight of spot crypto trading and the SEC oversight of token offerings. This split would replace the current enforcement‑by‑lawsuit approach with a clear rulebook for exchanges, stablecoins, and DeFi protocols. The Senate Banking Committee markup set for Thursday at 10:30 a.m. in room 538 will test whether the bill can survive a flood of amendments.

Market participants are watching closely because the bill's fate influences everything from which exchanges can serve U.S. customers to whether stablecoin issuers can offer interest‑like yields without becoming banks. A clear framework could lower compliance costs and attract more institutional capital. Currently, USDT and USDC together account for about $130 billion of circulating stablecoin supply, highlighting the systemic importance of any yield restrictions.

More than 100 amendments have been submitted, creating a high risk of legislative chaos that could stall or reshape the bill. Warren's amendment package includes provisions to deny Federal Reserve master accounts to crypto companies, effectively cutting them off from the banking system's core settlement infrastructure.

Other amendments target stablecoin yields that resemble deposit interest, a move backed by thousands of letters from the American Bankers Association. Prediction markets now price the bill's enactment at 60%, up from roughly 45% a month ago, reflecting increased optimism despite the amendment onslaught.

Denying master accounts would prevent crypto firms from accessing the Fed's payment services, forcing them to rely on correspondent banks for dollar settlements. This would raise transaction costs and slow down fiat‑on‑ramps for exchanges and stablecoin issuers.

If the markup advances the bill, a Senate floor vote could occur by early July, delivering regulatory clarity that may boost confidence among investors and firms. Market reaction has already shown Bitcoin (BTC) up 2.3% to $27,800 (market cap ≈ $540 billion) and Ethereum (ETH) up 1.8% to $1,850 (market cap ≈ $220 billion), while Coinbase (COIN) slipped 0.5% to $58 (market cap ≈ $15 billion).

These price moves suggest traders are betting that clearer rules will reduce litigation risk and lower compliance burdens for crypto‑related stocks. Conversely, if the amendments derail the bill, the regulatory limbo would persist, keeping stablecoin yields under scrutiny and leaving DeFi developers exposed to potential enforcement actions.

Benchmarks such as the S&P 500's 0.4% gain over the same period and the Nasdaq Crypto Index's 1.2% rise help contextualize the crypto‑specific moves, indicating that the sector is outperforming broader equities on the news.

Stablecoin issuers that offer yields resembling bank deposits could be required to obtain a banking charter or cease those products, unless they restructure rewards as activity‑based incentives like staking. This distinction aims to prevent a regulatory arbitrage that lets crypto firms mimic traditional bank products without oversight. The bill also includes developer safe harbors that would protect DeFi protocol creators from automatic criminal liability for the code they deploy, provided the protocol operates without centralized control.

This provision seeks to encourage innovation while still addressing illicit‑use concerns. Similar safe‑harbor concepts have appeared in recent EU MiCA discussions, showing a growing global consensus on protecting open‑source developers.

Watch for Thursday's markup outcome and any subsequent Senate floor vote schedule, as they will determine whether the U.S. finally adopts a unified crypto framework or remains in a lawsuit‑driven environment.
