SUMMARY OF THE ARTICLE
1.- What revolving credit cards are and why they can generate indefinite debt.
It is a Rotating credit that allows drawing up to a limit through small monthly instalments that renew automatically. Danger: these instalments barely amortize capital while interest compounds permanently, generating indefinite debt.
2.- First avenue: nullity for excessive interest.
The Spanish Supreme Court establishes that interest becomes excessive when it surpasses by more than 6 percentage points the average market rate applicable at signing. Critical: each subsequent interest rate increase is examined independently. If the bank raises the rate later, that modification may be excessive even if the initial rate was lawful.
3.- Second avenue: nullity for unfair contract terms.
Contract void when no clear explanation was provided BEFORE signing about revolving system mechanics, minimum amortization impact, compound interest, indefinite duration. Action for nullity is imprescriptible. Claim for recovery of excess amounts: 5 years from each payment.
For more than a decade, many financial institutions marketed revolving credit cards emphasizing only their apparent advantages. “Pay a fixed, affordable monthly installment,” they said. What they did not explain was the product’s actual mechanism: a small payment, high interest rates, virtually no capital amortization. The result is what the Bank of Spain calls the “snowball effect” and the courts known as “debtor captivity”. In this week’s article we examine the main grounds for a Revolving Card claim in 2026.
Excessive interest. When can it be challenged?
There are different grounds on which it is possible to lodge a Revolving Card claim. First, interest rates. The Spanish Supreme Court has established that in such products, interest may be considered excessive when it exceeds by more than 6 percentage points the average market rate applicable at the time of contracting.
This assessment should not be made only at the initial contract moment. If the institution subsequently increases the interest rate, that modification can be examined separately. In this way, it is prevented that institutions set a moderately low initial rate only to raise it substantially later. In such cases, if the new rate exceeds that differential above the applicable average rate at that moment, nullity can be declared from the point of increase onward.
Unfair terms. Nullity due to lack of pre-contractual disclosure.
A second avenue exists, equally important. The contract may be declared void when the consumer was not provided with clear and comprehensible information before entering into it. Specifically, the institution must effectively explain to the consumer: how the revolving mechanism works, the impact of the minimum capital repayment and compound interest, the possible indefinite duration of the credit, and the foreseeable debt evolution through representative examples.
If this information was not disclosed with sufficient transparency before signing or was delivered merely as a formality within general documentation without highlighting its real economic consequences, the contract could be declared unfair due to material lack of disclosure.
Limitation periods. Recent case law. Recovery of amounts paid.
The recent Supreme Court doctrine has also clarified a crucial matter. This is that the action for contract nullity is different from the action for restitution of sums.
.- The nullity of a contract for excessive interest is radical and, therefore, would not be subject to a limitation period.
.- However, the claim for recovery of amounts paid in excess of the capital drawn is subject to a time limit, as it is a personal action.
Currently, this period is five years. Furthermore, in the case of revolving credit cards, the High court has specified that calculation is made with respect to each monthly payment. This means the consumer can claim excess amounts paid within the five years preceding an out-of-court claim or the filing of a lawsuit.
Conclusion.
The recent Spanish Supreme Court case law has strengthened consumer protection regarding revolving credit cards, both through the excessive interest avenue and the lack of transparency route.
