Shares of financial companies in the United States and Britain weakened on Monday after President Donald Trump proposed placing a 10 per cent ceiling on credit card interest rates, a policy idea that investors fear could undermine a major source of income for banks. Reuters reported that the announcement unsettled markets, triggering declines across banking, consumer finance, and payment processing stocks.
Trump’s call for an interest rate cap raised concerns about the long-term profitability of consumer lending, particularly credit cards, which typically carry higher interest rates than other forms of borrowing. Analysts noted that limiting rates could sharply reduce earnings at a time when banks have benefited from elevated borrowing costs.
In U.S. markets, major lenders recorded noticeable losses. JPMorgan Chase, the largest U.S. bank, saw its shares fall by 2.5 per cent, while Bank of America slipped 1.6 per cent. Citigroup experienced a steeper decline of 3.7 per cent, reflecting its sizable exposure to credit card and consumer lending businesses. Wells Fargo also ended the session lower, with its stock down 1.5 per cent.
The impact of the proposal extended beyond the United States. In London, shares of UK-based financial institutions also came under pressure. Barclays, one of Britain’s largest banks, saw its stock drop 2.2 per cent, hitting its lowest level in almost a month. The decline suggested investor unease that regulatory sentiment around credit card pricing could spread to other major markets.
Companies focused on consumer finance were among the hardest hit, as their business models rely heavily on interest income from credit cards. Synchrony Financial recorded some of the steepest losses of the day, with its shares falling by as much as 11 per cent. Bread Financial and Capital One also suffered sharp sell-offs, with declines ranging between 8 per cent and 10 per cent. Investors appeared to be pricing in the risk that a rate cap would significantly compress margins and limit lenders’ ability to offset defaults.
American Express was not immune to the broader downturn. Its shares fell 3.8 per cent, despite the company’s focus on higher-income customers who typically carry lower credit risk. Market participants nonetheless viewed the proposal as a potential threat to the wider card-based lending industry.
Payment networks also saw their stocks edge lower. Visa and Mastercard each declined by 1.8 per cent, according to Reuters. Although these companies do not earn revenue directly from interest charges, their shares were dragged down by overall weakness in the financial sector and concerns about reduced transaction volumes if credit availability tightens.
Industry analysts warned that credit card interest income represents a critical revenue stream for banks, particularly in an environment of high rates. A mandated cap could force lenders to reassess their credit strategies, possibly leading to stricter lending criteria or reduced access to credit for higher-risk consumers.
While Trump’s proposal remains a political statement rather than formal policy, markets reacted swiftly to the potential implications. Investors remain cautious as uncertainty grows around whether the idea will gain legislative support or influence future regulatory decisions.
The episode highlights how sensitive financial stocks are to political signals, especially those affecting consumer lending. Until there is greater clarity on the likelihood of regulatory changes, banking and finance shares may continue to face volatility.
