Everyone wants lower credit card rates — but price controls have costs | Chris Cargill

The appeal is obvious: If prices are too high, force them down.

Unfortunately, economics doesn’t work that way — and decades of evidence show that interest-rate caps, however well-intentioned, end up hurting the very people they’re meant to help.

Interest rates are prices. They reflect inflation, the cost of capital and — most important — risk. When government imposes a legal ceiling on what lenders can charge, lenders don’t suddenly lend at a loss. Instead, they change who they lend to.

If risk can’t be priced, it gets rationed.

In practice, that means fewer loans, lower credit limits, tighter underwriting standards and entire categories of borrowers pushed out of the market. A rate cap doesn’t eliminate risk. It just makes lenders unwilling or unable to serve riskier customers.

This isn’t theory. It’s what actually happens.

Supporters of interest-rate caps often frame them as consumer protection for low-income and financially vulnerable households. But the strongest empirical evidence shows those households are the ones most likely to lose access to credit altogether.

Consider Chile. In 2013, the country sharply lowered its legal maximum interest rate on consumer loans. A peer-reviewed study in the Journal of Banking and Finance found that this change significantly reduced access to formal credit. Nearly 10% of households were excluded from bank credit entirely, with the largest effects concentrated among younger, poorer and less-educated borrowers.

In other words, the policy worked — just not in the way its advocates intended.

The same pattern appears in the U.S. A recent staff report from the Federal Reserve Bank of New York examined what happens when U.S. states impose tighter usury limits. Using detailed credit-bureau data, the authors found that high-risk borrowers experienced sharp declines in credit accounts and total borrowing after rate caps were imposed.

The weird bipartisan alliance to cap credit card rates is onto something | Carter Dougherty

Crucially, those borrowers did not become more financially stable. Delinquency rates did not improve. Access to credit fell, but financial distress did not.

When mainstream lenders pull back, demand for credit doesn’t disappear. It moves.

Households shut out of credit cards and traditional loans are pushed toward less regulated, higher-cost alternatives — payday lenders, pawn shops, informal borrowing or overdraft dependence. These options often come with higher effective costs, worse consumer protections and fewer paths to financial recovery.

Even borrowers who retain access don’t escape unscathed. When interest revenue is capped, lenders make it up elsewhere — through higher fees, reduced rewards or fewer no-fee products. Credit card rewards don’t vanish by accident. They’re funded by pricing that reflects risk.

A cap doesn’t eliminate costs. It redistributes and obscures them.

Some policymakers across the ideological spectrum argue that a temporary cap — say, 10% — would provide relief without long-term harm. But lenders can’t wait to see how long a cap lasts. They must adjust immediately.

That means credit lines are cut, accounts are closed and riskier borrowers are screened out the moment a cap takes effect. For many consumers, once access is lost, it isn’t easily restored — even after a cap expires.

A more effective, market-consistent approach would focus on:

• Increasing competition in consumer lending.
• Reducing regulatory barriers to entry.
• Improving transparency and financial literacy.
• Addressing inflation, which pushes nominal interest rates higher across the economy.

These reforms tackle the root causes of high borrowing costs without cutting off access to credit for millions of Americans.

The evidence from the United States and abroad is clear: Interest-rate caps don’t make credit universally cheaper. They make it scarcer — especially for those with the fewest alternatives.

For households living paycheck to paycheck, expensive credit is often bad. But no credit at all is worse.
