Why a 10% Rate Cap Would End Credit Card Perks

Capping credit card interest rates at 10% would not just change what borrowers pay. It would wipe out the rewards programs millions of Americans use every day.

Points, cash back, airline miles, airport lounges, and statement credits all depend on today’s credit card pricing model. Take that away, and the perks disappear with it.

That is not a theory. It is basic credit card economics.

Rewards Are Paid for by Interest Margins

Credit card rewards are not free. They are funded by a system that relies on interest income from cardholders who carry balances.

In simple terms, borrowers who pay high interest rates subsidize cardholders who pay their balance in full and earn rewards. That cross-subsidy is what allows issuers to offer generous points, miles, and benefits.

Cap interest rates at 10%, and that margin collapses.

When the margin disappears, issuers have only two choices:

• Eliminate rewards programs

• Restrict credit to only the safest borrowers

  
  

Either way, consumers lose.

Credit Cards Are a Three-Legged Stool

The current system works because three elements support it:

• Revolvers subsidize transactors Cardholders who carry balances help fund rewards for those who do not.

• Risk-based pricing expands access Higher rates for riskier borrowers allow lenders to serve more people, not fewer.

• Behavioral inefficiencies fund perks Missed payments, carried balances, and uneven usage help make rewards pencil out.

  
  

Remove one leg of that stool, and the system does not become fairer. It rebalances.

And the rebalancing always hits consumers in visible ways.

What Disappears First

If Congress imposes a 10% APR cap, the first casualties will be the features consumers like most:

• Cash-back rewards

• Airline miles and hotel points

• Card credits and bonus offers

• Lounge access and premium perks

  
  

Issuers cannot fund those benefits without interest income. They will not replace them out of goodwill.

At the same time, credit limits will shrink, and many cardholders will lose access altogether. Lenders will tighten standards to protect themselves, leaving fewer options for young workers, lower-income households, and small business owners.

Price Controls Always Shift Costs

A credit card interest rate cap sounds like a consumer win because it targets a visible price. But price controls never eliminate costs. They just move them.

In this case, the costs show up as:

• Fewer rewards

• Less access to credit

• More restrictive lending

• Higher fees elsewhere

  
  

Consumers end up paying more and getting less, just in different ways.

The Bottom Line

Credit card rewards exist because interest rates are allowed to reflect risk. Break that link, and the perks disappear.

A 10% APR cap would not punish banks. It would punish cardholders who value rewards, flexibility, and access to credit.

That is the tradeoff policymakers need to be honest about.
