A dispute between Coinbase and the American Bankers Association over stablecoin rewards has emerged as a new obstacle for the CLARITY Act ahead of a planned September vote. Coinbase Chief Policy Officer Faryar Shirzad warned that ABA-backed changes could "kill" the bill, while ABA President and CEO Rob Nichols said the group is seeking to strengthen—not block—the legislation. The GENIUS Act already prohibits stablecoin issuers from paying interest or yield, but the debate centers on whether affiliates such as crypto exchanges could offer interest-like rewards that draw funds from bank deposits. Shirzad said stablecoins are not bank deposits and that rewards should not automatically be classified as deposit interest. Nichols argues that deposits fund lending to small businesses, first-time homebuyers and agricultural operations, while bank deposits carry protections such as FDIC insurance. The dispute adds to broader questions around the CLARITY Act, including ethics provisions, enforcement authority and the congressional calendar.
