Revolving Credit Cards in Spain: Supreme Court Doctrine and How to Claim in 2026
Paying every month while the balance barely moves? Updated August 2026 guide: the six-point rule (judgment 258/2023), the APR/TEDR adjustment (judgment 69/2026), the lack of transparency route, five-year limitation per payment (judgment 350/2025), what can be recovered and how to claim step by step.
What a revolving credit card is and why the debt never goes down
A revolving card is an open-ended credit line. You do not repay what you spend at the end of the month; you repay through a recurring instalment that is either a fixed amount or a percentage of the outstanding balance. As you pay, the limit becomes available again — the credit "revolves". Interest, fees and insurance premiums that the instalment does not cover are added to the balance, so you can pay for years without materially reducing the principal. The Bank of Spain itself warns about this [snowball effect](https://clientebancario.bde.es/pcb/es/blog/tarjetas-en-modalidad-revolving-un-credito-que-hay-que-devolver.html).
The problem is not the card as such, but the combination of a high APR, a low instalment and successive drawdowns. When the instalment barely covers interest, fees and insurance, capital amortisation is minimal or even nil, and the balance can grow even though the customer pays every single month.
| Feature | Full-payment card | Deferred payment | Revolving |
|---|---|---|---|
| Repayment | End of month, in full | Fixed number of instalments | Indefinite, recomposing limit |
| Interest | Usually none | Agreed for that purchase | Continuous, on the whole balance |
| Duration | 30 days | Known in advance | Open-ended |
| Typical risk | Low | Moderate | Snowball effect |
How to tell whether your card is revolving: eight signs
- The contract or statement mentions "revolving", "flexible payment", "credit mode" or "fixed instalment".
- You choose a monthly amount (for example EUR 30, EUR 50 or a percentage of the balance).
- The available limit is restored as you pay.
- The statement shows interest month after month even without new purchases.
- The APR is well above a personal loan (typically 18–27 %).
- The balance barely moves despite years of payments.
- The card was offered in a shop, by telephone or with a pre-filled form.
- You were offered refinancing, a "payment holiday" or conversion into a loan.
When a revolving card can be usurious
The 1908 Usury Act (Ley Azcárate)
Spanish usury control still rests on the Act of 23 July 1908 for the Repression of Usury. A loan is void where the agreed interest is notably higher than the normal rate of money and manifestly disproportionate to the circumstances of the case. The consequence is radical nullity of the interest: the borrower repays only the principal drawn down and recovers everything paid in excess — interest, fees and insurance linked to the credit.
The six-point rule (Supreme Court judgment 258/2023)
The Full Court of the First Chamber, in judgment 258/2023 of 15 February, set an objective benchmark: in revolving cards, interest is *notably higher than normal* when it exceeds the market average rate for that product, at the date of the contract, by more than six percentage points. The comparison must be made with the specific revolving category, not with generic consumer credit, and always with the figures in force when the contract was signed — not today's.
