In a move that caught many observers off guard, President Donald Trump announced on Truth Social that he intends to impose a temporary 10% cap on credit card interest rates for one year, framing it as a way to end what he called the “ripping off” of American consumers by companies charging 20–30% or more.

The proposal has unexpectedly drawn praise from figures across the ideological spectrum. Progressive lawmakers like Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez—who have long championed tighter regulation of the credit card industry—found themselves in rare alignment with conservative voices such as Sen. Josh Hawley and Rep. Anna Paulina Luna, both of whom have previously sponsored similar 10% cap legislation.

Consumer advocates have spent decades arguing that sky-high rates exploit borrowers, especially as average credit card APRs climbed to around 19.65–23% in recent tracking data, with some cards pushing well into the 30% range. Total U.S. credit card debt has meanwhile ballooned to roughly $1.23 trillion, adding pressure on households already juggling mortgages, student loans, and other obligations.

Yet the banking industry responded swiftly and forcefully. Senior executives from JPMorgan Chase, Citigroup, and Bank of America warned during recent earnings calls that any hard cap would almost certainly force lenders to pull back credit—most severely affecting the very people who rely on cards the most: those with lower incomes and lower credit scores. Bank of America’s CEO described the likely outcome as “strict credit,” while industry groups, including the American Bankers Association, cautioned that frustrated consumers might simply turn to less-regulated alternatives such as buy-now-pay-later services, potentially trading one set of costs and risks for another.

Analysts point out additional complications. A cap would most likely not apply retroactively to existing balances due to significant legal hurdles, meaning relief would be limited to new borrowing. While some estimates suggest consumers could save up to $100 billion annually in interest if the policy took effect, the same forecasts predict major revenue losses for card issuers, likely prompting tighter underwriting standards and reduced access overall.

One smaller player, Bilt Rewards, moved quickly to announce new cards carrying a 10% rate for the first year, appearing to get ahead of any potential mandate. Larger, more credit-card-dependent institutions saw an immediate market reaction: shares of Capital One, for example, declined in the trading sessions that followed the announcement.

Whether the president’s statement translates into concrete policy remains uncertain. Implementation would almost certainly require either new legislation or significant action by the Consumer Financial Protection Bureau—both of which would face intense lobbying from the financial sector.

For now, the episode illustrates how quickly a single high-profile statement can momentarily unite longtime ideological opponents around the idea of consumer relief, even as the powerful institutions that profit from the current system push back just as quickly.
