A bold move or a costly blunder? That’s the question swirling around former President Donald Trump’s recent call for a one-year 10% cap on credit card interest rates. While the proposal aims to tackle the pressing issue of affordability, not everyone is convinced it’s the right approach. And this is the part most people miss: Hedge fund billionaire Bill Ackman has slammed the idea as a 'mistake' that could backfire spectacularly, leaving millions of Americans worse off.
In a now-deleted post on X, Ackman didn’t hold back. He argued that capping interest rates at 10% would force credit card lenders to cancel cards for millions of consumers. 'Without being able to charge rates adequate enough to cover losses and earn a return, lenders will have no choice,' Ackman wrote. 'These consumers will then be forced to turn to loan sharks, paying even higher rates and facing worse terms than before.' It’s a stark warning that raises serious questions about the unintended consequences of such a policy.
Trump’s announcement came via Truth Social on Friday, where he vowed to tackle lenders charging 'exorbitant' rates of 20% to 30%. 'The American Public will no longer be ripped off,' he declared, setting January 20, 2026, as the effective date for the proposed cap. But here’s where it gets controversial: Implementing such a cap would likely require congressional approval, and it’s unclear how Trump plans to bypass this hurdle. Is this a feasible solution, or a political stunt?
Ackman, CEO of Pershing Square Capital Management, acknowledged that lowering credit card interest rates is a 'worthy and important goal.' However, he believes a 10% cap isn’t the answer. Instead, he suggests fostering competition by creating a regulatory environment that encourages new entrants and innovative technologies. 'The credit card market is already highly competitive,' Ackman noted. 'Why not focus on making it even more so?'
Trump’s focus on affordability isn’t new. He’s repeatedly pledged to 'immediately bring prices down' during his time in office, and the issue has gained traction in recent elections. For instance, New York City Mayor Zohran Mamdani’s victory in November was fueled by his campaign’s emphasis on cost-of-living concerns. But Ackman’s critique highlights a critical tension: How do we balance consumer protection with the realities of a competitive market?
Here’s a thought-provoking question for you: Is capping credit card interest rates the best way to address affordability, or could it lead to more harm than good? Share your thoughts in the comments—let’s spark a discussion!
