How a 10% Credit Card APR Cap Could Raise Your Growth Costs
A 10% cap on credit card APR can raise your growth costs. If the rate goes down, why would acquisition get harder?
Picture a regional retailer rolling out a loyalty app and a co-branded card. The plan is simple: points fund repeat purchases, revolving balances fund the rewards, and a bank partner handles the risk.
Then a 10% cap becomes real enough to plan for, with today’s averages closer to 20% plus. JPMorganChase and others immediately talk about pulling back.
Here is the part most operators miss: when you compress the issuer’s margin, you do not just make credit cheaper. You change who gets approved, how much they get, and whether the rewards budget exists at all.
Banks protect the portfolio by tightening approvals, shrinking credit lines, and trimming points. Networks like Visa and Mastercard still run the rails, but your “free” retention loop quietly breaks. The customer who used to finance a basket now gets declined or gets no reason to prefer you.
And the spend does not disappear. It reroutes to alternatives like Klarna style pay-in-4, or to fee-heavy products that are easier to reprice.
