Complex Financial Products: Your Right to Information in Spain

🇪🇸 Read the original in Spanish

The marketing of complex financial products has left a deep mark on the Spanish judicial landscape, affecting thousands of savers who entrusted their capital to banking institutions without understanding the real risk of their investments. Instruments such as participaciones preferentes (preferred shares), obligaciones subordinadas (subordinated debt), multi-currency mortgages, or interest rate swaps (swaps) were sold for years as safe, high-yield products, when in reality they hid a high risk of capital loss. In the Spanish legal system, the consumer's right to information is not a mere formal formality, but a substantial and mandatory requirement. Any breach of this duty empowers citizens to claim the nullity of these contracts in court and recover their money.

What is a complex financial product and why is it different?

To understand the scope of the right to information, we must first define what is considered a complex financial product. Unlike traditional savings products, such as current accounts or fixed-term deposits (where the client knows the return in advance and the capital is guaranteed by the Fondo de Garantía de Depósitos [Deposit Guarantee Fund] up to 100,000 euros), complex products feature return structures linked to market variables, derivatives, or underlying assets that are difficult to understand.

Sector regulations classify instruments as complex if the investor can lose more money than initially invested, or if they are non-liquid—meaning they cannot be easily sold on the market to recover the money immediately. The complexity lies in the fact that the average client cannot assess the risk of the transaction on their own without an exhaustive, transparent, and fair explanation from the financial institution.

The legal framework: Financial consumer protection in Spain

The protection of financial product clients is structured in Spain through a robust regulatory framework that combines general consumer law with specific financial legislation.

1. Ley General para la Defensa de los Consumidores y Usuarios (RDL 1/2007)

The Real Decreto Legislativo 1/2007, de 16 de noviembre (Royal Legislative Decree 1/2007, of 16 November), which approves the revised text of the General Law for the Defence of Consumers and Users, establishes in its Article 8 the basic rights of consumers, placing protection against risks that may affect their economic interests and the right to correct information on different goods or services at the very top of the list.

Likewise, Article 60 of this same law imposes a duty on the business owner to provide relevant, truthful, and sufficient information on the main characteristics of the contract free of charge before the consumer is bound. In the financial sector, this information asymmetry is at its peak, which is why Spanish courts apply this principle with the utmost rigour.

2. The Ley del Mercado de Valores and the transposition of the MiFID regulations

Although the Ley de Servicios de la Sociedad de la Información (LSSI - Law on Information Society Services) regulates aspects of electronic contracting, the core of financial information obligations is found in the Texto Refundido de la Ley del Mercado de Valores (Revised Text of the Securities Market Law). This regulation incorporates the European MiFID (Markets in Financial Instruments Directive) directive, which classifies clients into "retail" (highest protection) and "professional".

Under this framework, financial institutions are obliged to:

• Act with diligence and transparency in the best interest of their clients.
• Carry out the Test de Conveniencia (Appropriateness Test) to assess whether the client has the necessary knowledge and experience to understand the product.
• Carry out the Test de Idoneidad (Suitability Test) when a financial advisory service is offered, to ensure that the product matches the client's investment objectives and financial capacity.

3. The Código Civil and the "vicio en el consentimiento" (defect in consent)

When a bank breaches its information duties, the contract to acquire the financial product may be flawed. Article 1261 of the Código Civil (Civil Code) establishes that there is no contract unless the consent of the contracting parties is present. If the client signed the contract under an erroneous belief about the risks of the product (caused by the bank's lack of information), a vicio en el consentimiento (defect in consent due to error) occurs, regulated in Article 1265 and following of the Civil Code. This error invalidates the contract if it falls upon the substance of the thing that was the object of the contract.

Concrete examples of financial malpractice

To visualize how the right to information operates in practice, we will analyze two common scenarios in Spanish courts.

Example 1: The case of Carmen's Participaciones Preferentes

Carmen, a 72-year-old retiree with no financial education, goes to her trusted bank branch to renew a fixed-term deposit of 30,000 euros that was maturing. The branch manager, whom she has known for fifteen years, offers her a "special product" that pays 6% annual interest, assuring her that it is "just like a fixed-term deposit, but with a higher return" and that she can withdraw her money whenever she wants with 48 hours' notice. Carmen signs the documents trusting her manager.

Two years later, Carmen needs to recover her 30,000 euros for a medical procedure, and the bank informs her that it cannot return the money because the product consists of participaciones preferentes (preferred shares), a perpetual instrument whose capital is not guaranteed and which trades on a secondary market with no liquidity at that time.

• Legal analysis: The bank flagrantly breached its duty of information. It did not perform the suitability test, concealed the perpetual nature of the product, and hid the risk of capital loss. Carmen has the right to sue for the nullity of the contract due to error in consent, requesting the return of her 30,000 euros plus legal interest, minus any coupon payments she had collected during that time.

Example 2: The interest rate Swap of an SME

Manuel is the administrator of a small transport company. To finance the purchase of three trucks, he requests a variable-rate mortgage loan of 250,000 euros (Euribor + 1.5%). During the signing of the loan, the bank requires him to subscribe to a "protection insurance against interest rate rises" (a swap or financial exchange contract). The bank explains the benefits in detail if the Euribor rises, but fails to inform him that if the Euribor falls (as historically occurred from 2008 onwards), Manuel will have to pay very high negative settlements to the bank, nor that the early cancellation of the swap carries a cost of 18,000 euros.

• Legal analysis: The swap is a complex derivative product. The lack of information regarding the scenario of falling interest rates and the cost of early cancellation constitutes a serious informational omission. Manuel can legally claim the nullity of the swap contract, demanding the return of all negative settlements that the company paid to the bank.

Practical steps: How to claim step-by-step

If you have discovered that you have contracted a complex financial product about which you were not properly informed, you should follow this orderly procedure to defend your rights:

1. Documentary gathering: Gather all the documentation for the product. This includes the acquisition contract, the CNMV (Comisión Nacional del Mercado de Valores - National Securities Market Commission) information brochure (if one existed), the appropriateness and suitability tests (demand a copy from the bank if you do not have them), settlement statements, and any commercial communications (emails, advertising brochures).
2. Complaint to the Servicio de Atención al Cliente (SAC): Submit a formal written complaint to the bank's Servicio de Atención al Cliente (Customer Service Department). In this document, you must clearly state that the information duties were breached and request the nullity of the contract or compensation for damages. The bank has a period of 1 month (if you are a consumer) or 2 months (if you are a legal entity) to reply.
3. Complaint to the Comisión Nacional del Mercado de Valores (CNMV): If the SAC rejects your claim or does not reply within the deadline, you can file a complaint with the Claims Service of the CNMV. Although its resolution is not binding on the bank, a favorable report from the CNMV determining that the bank did not inform you correctly is highly valuable evidence for the next step.
4. Judicial Route: If the previous phases do not yield results, you must file a civil lawsuit before the Juzgados de Primera Instancia (Courts of First Instance) of the plaintiff's domicile. This lawsuit will seek an action for nullity due to a defect in consent or, alternatively, the termination of the contract due to breach of information obligations, along with a claim for damages.

Deadlines, amounts, and key figures you must know

In the field of financial claims, keeping track of deadlines and amounts is critical to the success of the legal action:

• 4-year limitation period (caducidad): To request the nullity of the contract due to error in consent (vicio), the deadline is 4 years. The Tribunal Supremo (Supreme Court) has established unified jurisprudence determining that this 4-year period does not start counting from the signing of the contract, but from its consummation—meaning when an event occurs that allows the client to become aware of the error (for example, the suspension of dividend payments, the mandatory conversion of the product, or the closing of settlements).
• 5-year prescription period: If you opt for an action for damages due to breach of contract (Article 1101 of the Código Civil), the prescription period is 5 years from when the fulfillment of the obligation could be demanded (following the reform of Article 1964 of the Código Civil).
• 100,000 euros: This is the maximum limit guaranteed by the Fondo de Garantía de Depósitos per account and holder. Remember that complex financial products (shares, preferred shares, subordinated debt, non-guaranteed investment funds) are not covered by this fund in the event of the entity's bankruptcy.

Mistakes you must avoid

• Signing undated documents or documents with altered dates: Financial institutions sometimes try to remedy the lack of suitability tests by having them signed with a date posterior to the contracting of the product. Always check that the date of the test is prior to the signing of the product contract.
• Letting time pass after detecting losses: Inaction can work against you. Although the limitation periods start counting from consummation, delaying the claim makes it harder to gather evidence and can be judicially interpreted as a tacit acceptance of the product.
• Accepting trap agreements from the bank: Fearing a lawsuit, the bank may offer you a private agreement (such as exchanging your preferred shares for shares of the entity). Read the fine print carefully: these agreements usually include an express waiver clause preventing you from taking future legal action. Do not sign anything without independent legal advice.
• Not keeping commercial advertising: Advertising brochures and emails from the manager stating that the product was "safe" or "risk-free" have contractual value and serve as devastating evidence in a trial. Do not destroy any documentation.

Frequently Asked Questions (FAQ)

Can I claim if I signed a document that said "I know the risks of the product"?

Yes, absolutely. The Tribunal Supremo has reiterated that pre-drafted generic clauses (such as formulas stating "the client declares to know the risks of the investment") do not exempt the entity from its obligation to actively inform the client. The bank must prove that it provided specific, simple explanations adapted to the client's profile; the mere signature of a standard declaration of knowledge is not sufficient.

What happens if the bank where I contracted the product no longer exists or was absorbed?

The merger or absorption of banking entities does not extinguish contractual liabilities. The absorbing entity (the current bank) assumes all rights, obligations, and legal contingencies of the absorbed entity. Therefore, you must direct your claim and subsequent lawsuit against the bank that currently holds the universal succession of the business.

Do I have the right to claim if I made a profit during the first few years?

Yes. The fact of having received coupons or positive interest for a period of time does not validate the contract if it was signed under a substantial error regarding its overall risks. However, you must bear in mind that if the judge declares the nullity of the contract, the principle of reciprocal restitution of benefits will apply: the bank will return your initial investment plus legal interest, but you must return to the bank the profits or coupons you collected during the life of the product.

Can a company or SME claim for lack of financial information?

Yes, although the level of protection required by the courts varies. While a physical retail consumer is presumed to lack financial knowledge, in the case of companies, their corporate purpose, turnover, and whether they have their own financial departments are analyzed. If the SME is engaged in an activity unrelated to the financial sector (for example, a bakery or a construction company), it will be considered a retail client and will enjoy a high level of protection against the marketing of complex products such as swaps.

Summary

• Fundamental right: The right to receive clear, truthful, and understandable information about complex financial products is a basic pillar of consumer legislation in Spain.
• Bank's obligation: Financial institutions are required by law to perform appropriateness and suitability tests before selling any complex product to retail clients.
• Defect in consent: The lack of transparent information generates an essential error that invalidates the client's consent, allowing them to request the nullity of the contract.
• Strict deadlines: You have a general period of 4 years from the consummation of the contract to request nullity due to error, and 5 years for a damages action.
• Restitution of capital: A favorable nullity ruling obliges the bank to return 100% of the money originally invested, increased by the legal interest rate.
