JPMorgan Chase CEO Jamie Dimon went on Fox Business Friday evening and issued his most direct threat yet against the Digital Asset Market Clarity Act: if Congress lets stablecoin issuers pay yield, he wants no part of it.

"No, because it allows them to effectively pay interest on deposits, stablecoins or something like that, without protection that they should have," Dimon told host Maria Bartiromo on May 29, 2026 at 8:03 PM EDT. "The banks will not accept it that way. … I'm not worried about stablecoins but if it happened I'm telling you I will have nothing to do with it and it will eventually blow up."

The interview arrived at a pivotal moment. The Senate Banking Committee advanced its version of the Clarity Act through markup this month. The Senate Agriculture Committee passed its own version earlier this year. Staff from both committees are now merging the two bills — a required step before the full Senate can vote. After that, the House and a Trump signature stand between the bill and law.

The specific provision Dimon is targeting: a section allowing stablecoin issuers to offer yield-bearing rewards that function like high-yield savings accounts. Coinbase CEO Brian Armstrong and crypto industry lobbyists argue that blocking stablecoin yield is a straightforward attempt by banks to protect their deposit-funded business models from competition. Banks counter that if you offer bank-like products, you take on bank-like regulatory obligations.

Armstrong has been pressing that argument directly to Wall Street's biggest names — and the results have not been warm. At the World Economic Forum in Davos earlier this year, Dimon told him "You are full of s---," according to people familiar with the exchange who spoke to The Wall Street Journal. Bank of America CEO Brian Moynihan reportedly told Armstrong, "If you want to be a bank, just be a bank." Wells Fargo CEO Charlie Scharf declined to engage at all. Citigroup CEO Jane Fraser gave him less than a minute.

Dimon's Fox Business comments shift the dispute from boardroom whispers to public ultimatum. The world's largest bank by assets, on national television, explicitly threatening a legislative boycott is not a routine objection to a markup provision. It hands opponents of the yield clause a concrete talking point and raises the real question of whether any version of the Clarity Act that includes stablecoin yield can survive the Senate.

The stakes are high enough. Regulatory clarity on crypto market structure is the precondition for serious institutional capital deployment in the US. Every month the bill stalls is another month that capital either sits on the sidelines or routes offshore. Dimon's comments do not kill the legislation — but they give the bill's stablecoin yield opponents something they did not have before: the most prominent banker in America on record calling the provision a future blowup.

Armstrong has not responded publicly as of publication. Neither has JPMorgan.
