Senator Cynthia Lummis fired back at JPMorgan CEO Jamie Dimon over his criticism of the CLARITY Act, saying during a CNBC Squawk Box appearance that he either “hasn’t read the bill” or “wants to mislead people.”
The comment escalates the fight between banks and crypto firms as the U.S. market-structure bill moves closer to a Senate floor battle. Dimon has criticized the legislation and the crypto industry’s push to preserve stablecoin rewards, while Lummis argued that the bill already covers anti-money-laundering and Bank Secrecy Act obligations.
Lummis also called Dimon’s remarks toward Coinbase CEO Brian Armstrong “distasteful,” after the JPMorgan chief attacked Armstrong in the broader dispute over stablecoin rewards and banking competition.
The clash follows the latest Jamie Dimon attack on the CLARITY Act, where the bank-crypto fight moved from policy language into open personal conflict.
Stablecoin Rewards Remain The Pressure Point
The fight is centered on whether crypto platforms can offer rewards tied to stablecoin balances and activity without being treated like banks.
Banks argue that stablecoin rewards can pull deposits out of the banking system while avoiding bank-level rules. Crypto firms argue that rewards linked to trading, payments or platform activity should not be blocked like passive deposit interest.
That distinction has shaped the CLARITY Act for months. The current compromise limits bank-like payouts on idle stablecoin balances while preserving room for activity-based rewards. Coinbase has backed that structure because USDC remains one of its most important business lines, as shown by the earlier Coinbase USDC revenue debate.
For JPMorgan and other banks, the issue is competitive. Stablecoins can move dollars faster, settle outside banking hours and keep users inside crypto apps. For Coinbase and other exchanges, stablecoins are payments, collateral, trading liquidity and customer retention infrastructure.
Senate Fight Gets Sharper
The CLARITY Act has cleared Senate Banking and moved onto the Senate Legislative Calendar. The bill still needs floor time and final Senate support before it can advance, with stablecoin rewards now one of the main pressure points.
Banks want tighter limits on crypto platforms that pay users around stablecoin balances. Crypto firms want to keep rewards tied to platform activity, payments and trading use cases. The final language will decide how much room exchanges, wallets and stablecoin issuers have to compete with bank deposits without being treated like banks.
Lummis is now pushing back directly against JPMorgan’s criticism. Dimon is warning that the bill gives crypto too much room. Coinbase and other crypto firms are defending stablecoin rewards as part of the industry’s payments and trading infrastructure.
The fight is no longer abstract. If CLARITY moves forward in the Senate, the stablecoin-rewards language will decide how far banks can limit crypto’s dollar-payment business and how much of that market remains open to exchanges and fintech platforms.
