Banking Law and Participatory Finance Systems in Spain

1. Introduction

In Spain, participatory finance is most closely associated with crowdfunding and participatory-financing platforms (plataformas de financiación participativa or PFPs).

The system allows businesses, projects and individuals to obtain financing directly from multiple investors through an online platform. Depending on the model, investors may provide:

• loans;
• equity;
• other transferable securities; or
• other permitted investment instruments.

The Spanish framework is particularly important from a banking-law perspective because participatory finance can perform functions traditionally associated with banks—such as facilitating credit—without necessarily making the platform itself a bank.

The regulatory system therefore draws an important line between:

regulated crowdfunding intermediation and regulated banking activity.

2. Principal Legal Framework

Spain originally created a dedicated crowdfunding regime through Law 5/2015 of 27 April, on the Promotion of Business Financing.

Title V of that law established the Spanish regime for participatory financing platforms.

However, the framework was subsequently transformed by EU law.

The central current EU instrument is:

Regulation (EU) 2020/1503 on European crowdfunding service providers for business, commonly called the European Crowdfunding Service Providers Regulation (ECSPR).

Spain implemented the EU framework through, among other measures, Law 18/2022 of 28 September, which amended Spanish financial and crowdfunding legislation.

Accordingly, when analysing Spanish participatory finance today, it is necessary to distinguish:

1. the original Law 5/2015 framework;
2. the directly applicable EU Crowdfunding Regulation; and
3. subsequent Spanish amendments and supervisory rules.

3. What Is a Participatory Financing Platform?

A PFP provides an online mechanism connecting project owners with investors.

A simplified structure is:

Project owner → online platform → multiple investors

For example, a Spanish company needs €500,000 for expansion.

Instead of borrowing the entire amount from a bank, it could obtain financing through a crowdfunding platform:

500 investors × €1,000 = €500,000

The platform facilitates the transaction but does not necessarily become the borrower or lender itself.

This distinction is fundamental.

4. Crowdfunding Models

The principal models include loan-based crowdfunding and investment-based crowdfunding.

Loan-based model

Investors provide funds that the project owner must repay.

Example:

Investor → €2,000 loan → Spanish SME

The investor receives repayment according to the contractual terms, potentially with interest.

Investment-based model

Investors acquire securities or other permitted investment instruments linked to the project or company.

Example:

Investor → €2,000 → shares/securities issued by project company.

The investor's return may depend on the company's future performance.

5. Crowdfunding Is Not Automatically Banking

This distinction is central to Spanish financial law.

A crowdfunding platform generally does not become a bank simply because it facilitates lending.

Traditional banking involves activities such as receiving repayable funds from the public and granting credit within the regulated banking framework.

Participatory-finance platforms operate under a different regulatory model.

The relevant question is therefore:

What exactly does the platform do?

A platform that merely connects investors and project owners may fall within the crowdfunding regime.

A business that begins accepting repayable deposits from the public or conducting other reserved banking activities could enter a different regulatory category.

6. Supervisory Authority

The Comisión Nacional del Mercado de Valores (CNMV) is the principal Spanish authority for the authorization and supervision of crowdfunding service providers under the applicable framework.

At EU level, the European Securities and Markets Authority (ESMA) has important supervisory and regulatory functions under the ECSPR.

The Banco de España remains relevant where the activities of an entity fall within banking or payment regulation.

Thus:

Crowdfunding platform → CNMV/ECSPR

while:

Credit institution → banking supervisory framework

and some businesses can potentially fall within more than one regulatory regime depending on their activities.

7. Authorization

A platform providing regulated crowdfunding services generally needs the required authorization.

The regulatory assessment can cover:

• ownership;
• management;
• governance;
• capital/resources;
• business model;
• risk management;
• complaints handling;
• conflicts of interest;
• investor protection;
• operational systems;
• cybersecurity; and
• business continuity.

Under the EU framework, an authorized provider can benefit from the European regulatory passport for qualifying services.

This is a significant change from the earlier Spanish regime.

8. European Passporting

One of the major consequences of the ECSPR is the creation of a more harmonized EU framework.

A provider authorized under the EU crowdfunding regime can, subject to the Regulation's requirements and notification procedures, provide qualifying crowdfunding services across EU Member States.

This is different from the older situation in which national crowdfunding rules were more fragmented.

For Spanish platforms, passporting can therefore make cross-border business considerably more structured.

9. Investor Protection

Investor protection is a central element of the framework.

Crowdfunding investors can be retail investors with substantially less information and financial expertise than professional investors.

The regulatory system therefore addresses issues such as:

• information disclosure;
• risk warnings;
• suitability/appropriateness-related protections where applicable;
• complaints procedures;
• conflicts of interest;
• default information;
• project-owner information; and
• investor categorization.

The purpose is to reduce information asymmetry without eliminating the investment risk itself.

10. Key Investment Risks

Crowdfunding is not equivalent to a bank deposit.

An investor may face:

• borrower default;
• business failure;
• loss of invested capital;
• lack of liquidity;
• project delay;
• valuation uncertainty; and
• fraud or operational risk.

Accordingly, the regulatory framework emphasizes disclosure rather than promising that investment risk will disappear.

11. Risk Management by the Platform

A platform should have procedures addressing operational and financial risks.

Important areas include:

Credit risk

For loan-based projects, the borrower may fail to repay.

Operational risk

The platform itself may experience technological or administrative failure.

Cybersecurity

Unauthorized access could affect investor information or transaction systems.

Conflicts of interest

A platform could face conflicts if it has relationships with project owners or receives incentives connected with particular investments.

Business continuity

The platform needs arrangements allowing important investor and project information to remain accessible if the platform experiences disruption.

12. Project-Owner Disclosure

A project owner seeking financing must provide investors with sufficiently relevant information concerning the project.

Important information can include:

• identity of the project owner;
• business model;
• financial information;
• purpose of financing;
• risks;
• terms of the investment;
• repayment structure for loans; and
• relevant ownership and governance information.

For investors, this disclosure is fundamental because crowdfunding reverses the traditional information structure of bank lending.

A bank normally performs substantial internal credit analysis.

In crowdfunding, investors themselves may have to assess the project using standardized regulatory information.

13. Key Investment Information Sheet

The EU crowdfunding framework introduced a standardized Key Investment Information Sheet (KIIS).

This is intended to make important investment information easier for investors to assess.

The document can address matters such as:

• project owner;
• project characteristics;
• risks;
• financial condition;
• investment terms;
• default scenarios;
• investor rights; and
• charges.

The objective is not simply disclosure for its own sake but improved comparability and informed decision-making.

14. Default Rates

Loan-based crowdfunding creates a specific information problem.

Investors need to understand not merely the nominal interest rate but also the likelihood and consequences of borrower default.

Consequently, information concerning historical or expected defaults can be particularly important.

A platform advertising:

“12% annual return”

without adequately communicating associated credit risk could give investors an incomplete picture of the investment.

Regulation therefore places importance on balanced risk disclosure.

15. Banks and Crowdfunding Platforms

Banks and PFPs can coexist.

A bank may:

• provide financing to a project also seeking crowdfunding;
• provide payment or account services to a platform;
• invest in crowdfunding projects where legally permissible;
• acquire or partner with a fintech business; or
• provide additional credit to businesses financed through crowdfunding.

But the bank must distinguish its regulated banking activity from the platform's crowdfunding activity.

A crowdfunding platform cannot represent itself as a bank unless it actually holds the relevant banking authorization.

16. Payment Services

Payment processing creates another regulatory boundary.

If a crowdfunding platform handles payment flows, it must determine whether the relevant payment activities fall within the Payment Services Directive framework as implemented in Spain or require use of an authorized payment-service provider.

This can produce a structure such as:

Investor → authorized payment institution → crowdfunding platform → project owner

rather than the crowdfunding platform itself holding customer funds as though it were a bank.

17. Safeguarding of Funds

Where a platform is involved in financial flows, safeguarding becomes important.

The legal structure should distinguish:

• platform operating money;
• investor money; and
• project-owner money.

Mixing customer funds with the platform's own operational funds can create serious legal and insolvency risks.

The applicable treatment depends on the precise service and regulatory structure.

18. AML/CFT

Participatory finance can also raise anti-money-laundering and counter-terrorist-financing issues.

Depending on the activities and regulatory status of the participants, relevant requirements can involve:

• customer identification;
• beneficial-owner identification;
• transaction monitoring;
• suspicious-activity reporting;
• sanctions controls; and
• record keeping.

This is particularly important because online crowdfunding can involve numerous investors and geographically dispersed participants.

19. Consumer Protection

Retail investors need protection from misleading marketing.

A platform should not present crowdfunding as:

• guaranteed;
• equivalent to a bank deposit;
• risk-free;
• automatically liquid; or
• certain to generate a stated return.

The distinction between expected return and guaranteed return is legally and economically important.

20. Conflicts of Interest

A platform may have relationships with project owners.

Potential conflicts can arise where a platform:

• receives compensation for successfully funded projects;
• has an ownership interest in a project owner;
• invests through its own accounts;
• recommends projects; or
• provides ancillary services to project owners.

The regulatory framework therefore addresses conflicts-of-interest management.

The platform should have procedures capable of identifying, preventing and managing conflicts.

21. Portfolio Management and Automated Investment

Modern crowdfunding platforms may offer automated allocation tools.

For example:

Investor deposits €10,000 → algorithm allocates €1,000 across ten projects.

Where a platform provides a regulated portfolio-management-type service, additional regulatory requirements can become relevant.

The legal characterization depends upon precisely what the platform does.

Technology does not remove financial regulation.

22. Secondary Markets

Liquidity is an important concern.

An investor who purchases a crowdfunding investment may not be able to sell it immediately.

The EU crowdfunding regime permits certain mechanisms facilitating investor exit, but a crowdfunding platform should not imply that an investment is automatically as liquid as a listed share.

This distinction is particularly important for retail investors.

23. Banking-Sector Impact

Participatory finance can compete with or complement traditional bank lending.

Traditional model

Bank → loan → SME

Participatory model

Many investors → platform → SME

The second model can diversify sources of finance.

For banks, it creates both competitive and partnership opportunities.

Banks can continue providing:

• senior secured lending;
• revolving facilities;
• payment services;
• treasury services; and
• acquisition finance,

while crowdfunding can provide alternative capital.

24. Insolvency

If a project owner becomes insolvent, the investor's position depends upon the legal instrument used.

Loan investment

Investors become creditors according to the relevant contractual and insolvency ranking.

Equity investment

Investors generally bear equity risk and rank differently from creditors.

This distinction must be communicated clearly.

A crowdfunding platform should not make investors believe that equity and debt investments have equivalent protection.

25. Case Law

A major qualification is necessary here: there is relatively limited published Spanish and EU case law directly interpreting the modern ECSPR regime, because Regulation (EU) 2020/1503 is comparatively recent.

It would therefore be unsafe to manufacture Spanish “crowdfunding cases” simply to reach a six-case list.

Instead, the following cases provide important closely related judicial principles concerning financial intermediation, investor protection, information and unfair contractual terms.

1. CJEU — Kásler and Káslerné Rábai v OTP Jelzálogbank, C-26/13, 30 April 2014

The CJEU examined transparency under the Unfair Terms Directive.

The Court explained that transparency can require consumers to understand the economic consequences of contractual terms, not merely their grammatical meaning.

Participatory-finance relevance: Crowdfunding investors need meaningful information about economic risks and obligations rather than merely technical contractual wording.

2. CJEU — Van Hove v CNP Assurances, C-96/14, 23 April 2015

The case concerned an insurance contract and the transparency of contractual provisions.

The Court emphasized the importance of allowing consumers to understand how contractual terms operate in practice.

Relevance: Crowdfunding risk disclosures should communicate practical consequences rather than rely exclusively on technical terminology.

3. CJEU — Gutiérrez Naranjo and Others, Joined Cases C-154/15, C-307/15 and C-308/15, 21 December 2016

The proceedings arose from Spanish consumer-finance litigation.

The CJEU reinforced the importance of effective protection against unfair contractual terms.

Relevance: Standard-form crowdfunding agreements remain subject to applicable consumer-protection principles where consumers are involved.

4. CJEU — Andriciuc and Others v Banca Românească, C-186/16, 20 September 2017

The Court considered transparency and the information necessary for consumers to understand financial risks.

The case involved foreign-currency loans rather than crowdfunding.

Relevance: It demonstrates the wider EU principle that financial consumers should receive information allowing them to appreciate economically significant risks.

5. CJEU — Gómez del Moral Guasch v Bankia, C-125/18, 3 March 2020

The case concerned transparency of a mortgage contractual mechanism.

The Court emphasized the importance of information enabling consumers to understand the economic functioning of contractual terms.

Relevance: Similar principles can inform the assessment of whether crowdfunding disclosures adequately explain material financial consequences.

6. CJEU — Banco Primus v Gutiérrez García, C-421/14, 26 January 2017

The Court considered unfair terms and consumer protection in a financial-contract context.

Relevance: Crowdfunding platforms dealing with retail investors must account for mandatory consumer protections applicable to their contractual arrangements.

26. Spanish Financial-Consumer Jurisprudence

Spanish Supreme Court jurisprudence on complex financial products is also relevant by analogy.

The Court has repeatedly emphasized the importance of adequate information in financial transactions involving retail customers.

Cases involving swaps, structured products and other complex financial instruments should not, however, be described as direct precedents on crowdfunding unless the judgment actually concerns a crowdfunding platform.

That distinction matters because the ECSPR creates a specialized regulatory regime.

27. Example: Spanish Crowdfunding Loan

Suppose a Spanish technology company wants €1 million.

It obtains:

€1m through a regulated crowdfunding platform

from:

400 retail investors.

Each investor contributes €2,500.

The platform must structure the transaction under the applicable crowdfunding framework.

Important legal questions include:

1. Is the platform properly authorized?
2. Is the project eligible?
3. Has the required investor information been provided?
4. Are risks accurately disclosed?
5. Are conflicts properly managed?
6. Are payments handled through an appropriately regulated mechanism?
7. Are investors correctly informed about default risk?
8. What happens if the borrower defaults?
9. What happens if the platform itself fails?
10. Are cross-border investors involved?

The platform is therefore not merely a website connecting two parties. It operates within a structured financial regulatory environment.

28. Example: Bank + Crowdfunding

Suppose a Spanish SME needs €5 million.

It obtains:

• €3 million senior bank loan; and
• €2 million through crowdfunding.

The bank may have first-ranking security over certain assets.

Crowdfunding investors may have unsecured or differently ranked claims.

The financing documents must therefore clearly establish:

priority + security + intercreditor rights + enforcement + insolvency ranking.

The bank cannot assume that crowdfunding investors have the same rights as the bank.

29. Cross-Border Crowdfunding

The EU framework is particularly significant for cross-border activity.

A Spanish-authorized crowdfunding service provider can potentially offer qualifying services to investors or project owners elsewhere in the EU under the harmonized framework.

This reduces some of the fragmentation associated with the former national regimes.

Nevertheless, providers must consider:

• investor-protection requirements;
• language and disclosure;
• AML obligations;
• payment arrangements;
• tax consequences;
• national company law; and
• insolvency rules.

30. Relationship With Traditional Banking Law

The relationship can be summarized:

31. Key Legal Risks

For Spanish participatory-finance businesses, the principal risks include:

Unauthorized activity

Operating outside the authorization perimeter.

Misleading disclosure

Understating investment risk or presenting returns as certain.

Credit risk

Borrowers may default.

Operational risk

Platform failure can affect thousands of investors.

Cyber risk

Online financial infrastructure can be targeted.

Conflicts

Platform incentives may affect project selection or presentation.

Insolvency

Investors need clarity concerning what happens if either the project owner or platform becomes insolvent.

Regulatory perimeter

A business can unintentionally move from crowdfunding into another regulated activity.

Conclusion

Spain's participatory-finance system has evolved from the national regime established by Law 5/2015 into the substantially harmonized EU framework established by Regulation (EU) 2020/1503, supplemented by Spanish reforms including Law 18/2022.

The system permits businesses to raise finance through regulated platforms connecting them with multiple investors. Its principal legal concerns are authorization, disclosure, investor protection, conflicts of interest, credit and operational risk, payment arrangements, AML/CFT, cybersecurity, insolvency and cross-border activity.

The banking-law distinction is particularly important: a crowdfunding platform is not automatically a bank, and facilitating loans does not by itself authorize deposit-taking or other activities reserved for credit institutions.

Direct judicial interpretation of the modern ECSPR remains limited. Accordingly, cases such as Kásler*, Van Hove, Gutiérrez Naranjo, Andriciuc, Gómez del Moral Guasch and *Banco Primus are best treated as general EU financial-consumer and transparency authorities, not as direct precedents on Spanish crowdfunding regulation. For formal legal work, the current text of Regulation (EU) 2020/1503, Law 18/2022, BOE materials, CNMV guidance and CJEU/CENDOJ records should be checked before relying on a particular provision or judgment.
