The same product, four very different exposures

The legal risk of a revolving credit product varies with who issues it, how it is sold and how old the portfolio is. Legacy exposure usually weighs more than the new contract.

Legacy portfolio

The past weighs more than the new contract

"You can have had flawless terms and conditions since last year and still be exposed through contracts signed a decade ago, with pre-contractual documentation you would not defend today. The review must start with the live portfolio, not with the new product."

Card issuers

The minimum payment is at the heart of the debate

"What decides most lawsuits is not the interest rate itself, but whether the customer could understand that, by paying the minimum, the principal barely goes down. That is proven with the example shown to them before signing."

Point-of-sale financing

Fast sign-up, hard proof

"When the contract is signed at a counter or on a phone in two minutes, the burden of proving that the pre-contractual information was provided and that the customer could read it falls on the issuer, and it is usually the weakest link."

Lending fintechs

Product design and legal design go together

"In a digital-native product, transparency is won or lost in the interface: what is visible without expanding anything, what takes an extra click and what record is kept of what the user saw. Perfect terms and conditions will not save a badly designed screen."

How we got here

The current revolving credit regime was not built in one go: it is the result of a 1908 law, two waves of case law and a specific transparency rule.

1
1908

The Usury Act (Ley de Represión de la Usura)

The law that is still deciding lawsuits more than a century later. It allows a loan to be declared void when its interest is notably higher than the normal interest rate and manifestly disproportionate to the circumstances of the case. Its consequence is drastic: the borrower repays only the principal.

2
2015 – 2020

The Supreme Court applies the usury test to revolving credit

Two judgments set the course: first, the Court accepts that the Usury Act applies to this type of credit; then, it specifies that the benchmark is neither the statutory interest rate nor the rate for consumer credit in general, but the average rate for transactions in this specific category published by the Bank of Spain.

3
2020

A specific transparency rule

Spain approves a ministerial order on revolving credit that strengthens three things: prior information with representative examples, periodic communication during the life of the contract, and the duty to warn customers when the payment they have chosen barely reduces the principal.

4
2022 – 2023

The usury threshold becomes objective

The Supreme Court sets a quantitative criterion for determining when a rate is notably higher than normal. This brings the predictability the sector had been asking for and shifts the debate from price to the transparency test.

5
Looking ahead

Periodic credit limit review

The EU consumer credit reform adds specific obligations for this product: periodically reviewing the credit limit granted, alerting consumers when their balance is not going down, and offering faster repayment options.

What is at stake in a revolving credit portfolio

The consequences are not proportionate to the defect: a transparency problem in the standard terms affects every contract signed on that template, not just one.

Nullity for usury: if the rate is held to be notably higher than normal and disproportionate, the contract is declared void and the customer only has to repay the principal drawn down, and everything charged above that amount must be refunded.

Nullity of the clause for lack of transparency: even if the rate is not usurious, the interest clause can be struck down if the customer could not understand its real economic burden. The usual effect is that the contract remains in force with no interest on the principal.

Portfolio effect: the defects lie in the standard terms and in the sales process, not in the individual contract. An adverse judgment on one contract template anticipates the outcome for every contract that uses the same template.

Transparency The minimum payment

Failing to warn customers, with a clear example, that by paying only the minimum the debt can drag on for many years is today the most effective argument against the issuer in court.

Claims Cost of defense

Beyond the outcome of each lawsuit, the aggregate cost of defense, court costs and interest in a mass-claims scenario can exceed the margin the product has earned over years.

Supervision Bank of Spain complaints

The reports of the supervisor’s complaints service identify patterns by institution and by product. An unusual volume of complaints about this product draws attention to all of your retail lending operations.

Revolving credit: common questions

What exactly is revolving credit?

It is a form of consumer credit with a credit limit that replenishes as the customer repays. Unlike a term loan, there is no fixed repayment schedule: the customer draws down funds, pays an installment and has credit available again.

It is usually offered through credit cards and credit lines linked to point-of-sale financing. Its flexibility is its commercial advantage and, at the same time, the source of almost all of its legal problems.

Why does it generate so much litigation?

Because of a combination of three factors that do not occur together in any other retail product:

  • Interest rates significantly higher than those on fixed-term consumer credit.
  • A repayment mechanism the average customer does not anticipate: with the minimum payment, the principal can take years to go down.
  • Sign-up that is often quick, at the point of sale or online, with pre-contractual documentation that is hard to prove years later.

The result is a product where claims do not arrive one by one, but in batches.

When is the rate applied considered usurious?

The 1908 Usury Act sets two cumulative requirements: the interest must be notably higher than the normal interest rate and manifestly disproportionate to the circumstances of the case.

Case law has made clear that the benchmark is the average rate for transactions in this same category published by the Bank of Spain, not the statutory interest rate or the rate for consumer credit in general. More recently, it has set an objective margin beyond which that threshold is deemed to be exceeded, which has given the sector predictability.

What happens if the contract is declared usurious?

The consequence is the nullity of the contract, not simply a reduction of the interest. The borrower only has to repay the principal actually drawn down, and the lender must refund everything received above that amount: interest, fees and linked insurance.

This is a far more severe consequence than that of a lack of transparency, which is why the pricing policy deserves a documented, periodic review.

And if the problem is transparency rather than price?

The transparency test applies even if the rate is acceptable

  • It is not enough for the clause to be incorporated into the contract and grammatically understandable.
  • The customer must be able to understand the real economic burden they are taking on: how much they will pay, and for how long, with the payment they have chosen.
  • The burden of proving that this understanding was made possible lies with the party that drafted the standard terms, that is, the issuer.
  • The typical effect of a lack of transparency is the removal of the agreed interest, while the rest of the contract remains in force.
What information must be provided during the life of the contract?

Spain’s product-specific rules strengthen periodic information: statements detailing drawdowns, interest and fees, and an express warning when the payment amount chosen does not significantly reduce the principal.

They also require advance notice of any change to the credit limit or terms. And the EU consumer credit reform adds a periodic review of the credit limit granted and the duty to offer alternatives to customers whose balance is not going down.

Can the credit limit be raised without reassessing the customer?

It is a common and highly exposed practice. Raising the available credit based on tenure, good payment behavior or automatically, without reviewing the cardholder’s current repayment capacity, is hard to defend against a claim.

The practical recommendation is simple: every significant credit limit increase must be backed by a documented reassessment of repayment capacity, with the same traceability as the initial approval.

Where should a portfolio review start?

With an inventory of historical terms and conditions. Almost no institution has a clear map of how many contract versions coexist in its live portfolio, since when each one was used and what pre-contractual documentation came with it.

That inventory lets you segment the exposure and make informed decisions on where to defend, where to settle and which contracts to renew on new terms. Without it, litigation strategy is improvised claim by claim.

Practical guide: shielding the product and the portfolio

The defense of a revolving credit product is built in three layers: the price charged, the understanding created before signing, and the evidence that both happened. Failing at any one of the three leaves the portfolio exposed.

Pricing

A documented and reviewed interest rate policy

Regularly compare your rate with the average rate published by the Bank of Spain for this category, keep a written record of the comparison and of your pricing criteria, and set a review procedure for when the benchmark moves.

Understanding

Representative examples before signing

The decisive element is the simulation showing what happens if the customer pays only the minimum: the total amount paid and the time until the debt is repaid. It must be visible without expanding anything, on the same medium where the contract is signed, and it must be recorded.

Evidence

A record of what the customer saw and when

For online sign-up, keep the version of the screen, the time of acceptance and the document provided. At the point of sale, keep a dated acknowledgment of receipt of the pre-contractual documentation. Without this, the burden of proof works against you.

Checklist: 10 points to review your revolving credit product

  1. Take an inventory of every version of the terms and conditions live in your portfolio, with dates of use and the volume of contracts linked to each one.
  2. Check that the interest clause passes the transparency test: placement, font size, wording and no dilution among other terms.
  3. Verify that there is a representative repayment example with the minimum payment, accessible before signing and not buried in an annex.
  4. Compare the rate you apply with the average rate published by the Bank of Spain for this category, and document the comparison in writing.
  5. Review the content and frequency of statements, including the warning when the payment does not significantly reduce the principal.
  6. Define the credit limit change procedure: who approves it, based on what prior analysis and with how much advance notice to the customer.
  7. Make sure that every significant increase in available credit is preceded by a documented reassessment of repayment capacity.
  8. Check the evidence that pre-contractual documentation was delivered in every channel, especially at the point of sale and online.
  9. Review linked ancillary products (insurance, fees) and how they are reflected in the total cost disclosed to the customer.
  10. Define your claims response strategy by portfolio segment, instead of handling claims case by case without common criteria.

Revolving credit in practice

The five points that decide a revolving credit lawsuit

When a claim arrives, the dispute is always about the same five pieces: the price, the clause, what was shown before signing, what was communicated afterwards and what evidence the issuer keeps. This section goes through them one by one.

Comparison of the rate applied with the average benchmark rate1) Price

The rate against its benchmark

The comparison is not made against the statutory interest rate or consumer credit in general, but against the average rate for this specific category published by the supervisor. Documenting that comparison is cheap; not having it is expensive.

  • Correct, up-to-date benchmark
  • Pricing criteria in writing
  • Review when the benchmark moves
Transparency review of the interest clause2) Clause

Incorporation and transparency

Two different filters. The first asks whether the clause validly became part of the contract; the second, whether the customer could understand what it cost them. Passing the first and failing the second is the most common scenario.

  • Placement and legibility
  • No dilution among other terms
  • Understandable economic burden
Periodic information and statements for revolving credit3) Life of the contract

What is communicated each month

The statement is not an administrative formality: it is evidence of diligence. It must let customers see how much they have paid, how much principal they have repaid and what happens if they keep the current payment.

  • Breakdown of drawdowns and interest
  • Alert if the principal barely goes down
  • Advance notice of credit limit or rate changes
Consequences by type of defect foundMap of consequences

The consequence of each defect

Usury

Nullity of the contract. The customer repays only the principal drawn down, and the issuer refunds everything charged above that amount.

Transparency

Nullity of the interest clause. The contract survives, usually with no interest on the principal lent.

Information

A transparency breach with administrative consequences, and evidence that counts against the issuer in the civil lawsuit.

Understandable cost

Requires a minimum payment simulation: customers cannot work out the real repayment period or the total amount on their own.

The fixed repayment schedule already shows the total payable and the number of installments. Understanding is immediate.

Repayment capacity assessment

Initial and periodic. Available credit replenishes and the limit can be raised, so the initial analysis goes out of date.

Information during the contract

Periodic statement with a warning if the principal barely goes down, and advance notice of changes to the limit or terms.

Information on the status of the loan and notice of changes, without the insufficient-repayment alert.

Usury risk

High: the rate is compared with the specific benchmark for this category, which is notably higher than the benchmark for term credit.

Lower in practice, although the same test applies, with its own market benchmark.

Portfolio exposure

High and correlated: the defects lie in the standard terms and affect all contracts at the same time.

More contained, unless there are systematic defects in the contract template or in the pre-contractual documentation.

Red flags: five symptoms of an exposed portfolio

If you recognize two or more of these situations, it is worth opening a portfolio review before the first adverse judgment sets the timetable for you.

  • There is no inventory of the live versions of the terms and conditions, or of the volume of contracts linked to each one.
  • The minimum payment repayment example is not shown before signing, or it sits in an annex that has to be downloaded.
  • There is no documentary record of the comparison between the rate applied and the benchmark published by the supervisor.
  • The limit is raised automatically based on tenure or payment behavior, without a new assessment.
  • Claims are answered case by case, with no common criteria for conceding, settling or defending by segment.
Operational glossary

Key revolving credit concepts

These terms appear in lawsuits, expert reports and requests from the complaints service. Your product, risk and legal teams should use them with the same meaning.

RevolvingProduct

Credit with a replenishing limit

A form of credit in which the limit granted replenishes as the customer repays, with no fixed repayment schedule. It is mainly offered through credit cards and lines linked to point-of-sale financing.

Commercial flexibility, legal complexity.
Minimum paymentMechanics

Minimum monthly payment due

The lowest amount the customer can pay each month. When it is close to the interest accrued, the principal barely goes down and the debt drags on for years. It is at the heart of the transparency debate.

Must be illustrated with an example before signing.
UsuryPrice

Interest notably higher and disproportionate

The test under the 1908 Usury Act, with two cumulative requirements. Its consequence is the nullity of the contract, not a reduction of the rate.

Compared with the benchmark for the category.

TransparencyTest

Substantive transparency test

An examination of whether the consumer could know the real economic and legal burden of the contract. It is separate from, and independent of, the incorporation test, which only looks at whether the clause validly became part of the contract.

The burden of proof lies with the party that drafted the standard terms.
Credit limitManagement

Revolving credit regulation in Spain: legislation and case law

Few retail financial products concentrate as much legal tension as revolving credit. Its regime does not come from a single rule, but from the overlap of a 1908 law that remains fully in force, a body of case law built over the last decade and a specific transparency rule adopted in Spain for this particular product.

Usury: a 1908 law applied to a 21st-century product

The Usury Act allows a loan to be declared void when its interest is notably higher than the normal interest rate and manifestly disproportionate to the circumstances of the case. What sets revolving credit apart is that its rates are structurally far above those of fixed-term consumer credit, which has forced the courts to specify the correct benchmark: not the statutory interest rate, nor consumer credit in general, but the average rate for this specific category published by the Bank of Spain.

From the debate on price to the debate on transparency

As the usury criterion has become more objective, the dispute has shifted to the substantive transparency test. The question is no longer how much the credit costs, but whether the consumer could understand the economic burden they were taking on. The decisive point is nearly always the same: whether they were told, with a specific example and before signing, how much they would end up paying, and for how long, if they paid only the minimum.

Spain’s specific transparency rule

In 2020, Spain approved a ministerial order on this product that strengthens three areas: pre-contractual information, with representative examples of different payment scenarios; periodic information during the life of the contract, including an express warning when the payment chosen does not significantly reduce the principal; and the assessment of repayment capacity, both at approval and when the limit is raised.

What the EU consumer credit reform adds

The EU consumer credit reform introduces additional obligations specific to open-ended and revolving credit agreements: periodic review of the credit limit granted, alerts to consumers whose balance is not going down, and the duty to offer them faster repayment options. For Spanish issuers, this comes on top of what national rules already require rather than replacing it.

Where we start

With the inventory of terms and conditions. Before discussing litigation strategy, you need to know how many contract versions coexist in the live portfolio, how many contracts sit under each one and what pre-contractual documentation came with each version. That map lets you segment the exposure and make informed decisions on where to defend, where to settle and which contracts to renew. Without it, every claim is answered as if it were the first.
