Open Banking in Switzerland: Standards, Adoption, and Market Impact
Open banking — the practice of providing third-party access to bank customer data and payment initiation through standardised application programming interfaces (APIs) — is advancing in Switzerland through a market-driven approach that contrasts with the regulatory mandates adopted in the European Union and the United Kingdom.
Overview
Unlike the EU, where the second Payment Services Directive (PSD2) mandates that banks provide API access to authorised third parties, Switzerland has not introduced legislative requirements for open banking. The Swiss approach relies on voluntary industry initiatives, market demand, and competitive dynamics to drive API adoption and data sharing.
This voluntary model reflects Switzerland’s broader regulatory philosophy of proportionality and market orientation. Proponents argue that it avoids the compliance costs and implementation challenges of mandated open banking whilst allowing the market to develop solutions that meet genuine commercial needs. Critics contend that the absence of regulatory compulsion results in slower adoption and fragmentation, disadvantaging fintech companies and consumers relative to their EU counterparts.
Industry Initiatives
Swiss Fintech Innovations (SFTI)
The Swiss Fintech Innovations association has played a central role in advancing open banking standards in Switzerland. SFTI, which includes representation from major Swiss banks, fintech companies, and technology firms, has published API specifications for common banking functions including account information, payment initiation, and standing orders.
The SFTI Common API framework provides a standardised interface that enables third-party applications to access banking data and initiate payments with the customer’s consent. Whilst adoption is voluntary, the framework provides a reference standard that reduces integration costs and promotes interoperability.
OpenBankingProject.ch
The OpenBankingProject.ch initiative has developed an open-source API platform for the Swiss banking market. The project provides technical specifications, reference implementations, and testing tools that facilitate API adoption by Swiss banks and third-party providers.
Individual Bank Initiatives
Several Swiss banks have launched their own API programmes, providing developer portals, sandbox environments, and production APIs that enable third-party integration.
SIX has developed API infrastructure that supports connectivity between banks and fintech companies, leveraging its position as Switzerland’s financial market infrastructure operator.
Major cantonal banks and universal banks have introduced API platforms that enable account aggregation, payment initiation, and data sharing with authorised third parties. The scope and sophistication of these platforms vary significantly across institutions.
Swiss neobanks and digital banking platforms — born in the digital era — typically offer more comprehensive API capabilities, reflecting their technology-first architectures and openness to third-party integration.
Regulatory Framework
Switzerland’s regulatory approach to open banking is characterised by facilitation rather than mandate.
FINMA has not issued specific regulations requiring banks to provide API access. However, the broader regulatory framework provides relevant context:
Data protection. The Swiss Federal Act on Data Protection (FADP) governs the processing and sharing of personal data, including banking data. Customer consent is a fundamental requirement for any data sharing, and banks must ensure that third-party access complies with data protection obligations.
Banking secrecy. Swiss banking secrecy — protected under Article 47 of the Swiss Banking Act — restricts the disclosure of client information. Open banking data sharing requires explicit customer consent to override secrecy protections, and banks must implement appropriate controls to ensure that consent is informed and revocable.
Financial Services Act. The FinSA imposes conduct requirements on financial service providers, which may apply to third-party providers accessing banking data through APIs.
AML obligations. Third-party providers that access banking data or initiate payments may be subject to anti-money laundering obligations, depending on the nature of their activities.
The absence of a PSD2-equivalent regulation means that Swiss banks are not obliged to provide standardised APIs, respond to third-party access requests within specified timeframes, or adopt specific authentication standards for open banking. This creates both flexibility and uncertainty for fintech companies seeking to build services on banking data.
Use Cases and Applications
Open banking in Switzerland is enabling several categories of application:
Account Aggregation
Multi-bank account aggregation — providing customers with a consolidated view of their financial holdings across multiple institutions — is one of the primary use cases for open banking. This capability is particularly valuable in Switzerland, where wealthy individuals frequently maintain relationships with multiple banks.
Swiss WealthTech platforms leverage open banking APIs to aggregate portfolio data, providing comprehensive wealth reporting and analytics across custodian banks.
Payment Initiation
Open banking payment initiation enables third-party applications to trigger payments directly from a customer’s bank account, bypassing card networks and reducing transaction costs. This capability is relevant for e-commerce, bill payment, and peer-to-peer transfer applications.
The development of payment initiation APIs in Switzerland intersects with the broader evolution of the Swiss payment provider landscape, creating new competitive dynamics between traditional payment methods and API-driven alternatives.
Personal Financial Management
Personal financial management (PFM) applications use banking data to provide customers with insights into their spending patterns, savings progress, and financial health. These tools — whether offered by banks themselves or by third-party fintech companies — rely on access to transaction data through APIs or screen-scraping techniques.
Lending and Credit Assessment
Open banking data can enhance credit assessment by providing lenders with a more comprehensive view of a borrower’s financial position. Transaction data, income verification, and spending analysis can supplement traditional credit scoring methods, potentially improving lending decisions and expanding access to credit.
Embedded Finance
The integration of financial services into non-financial platforms — known as embedded finance — is enabled by open banking APIs. This includes incorporating account information, payments, and lending into business software, e-commerce platforms, and consumer applications.
Challenges and Barriers
Several challenges constrain the development of open banking in Switzerland:
Fragmentation. The absence of a regulatory mandate has resulted in varied API implementations across banks, creating integration complexity for third-party providers. Whilst industry standards exist, adherence is voluntary and inconsistent.
Banking secrecy culture. Switzerland’s strong tradition of banking secrecy creates cultural resistance to data sharing, even with customer consent. Some institutions view open banking as fundamentally at odds with the privacy principles that have underpinned Swiss banking’s reputation.
Liability and risk. Open banking introduces new risks related to data security, fraud, and liability allocation between banks and third-party providers. The absence of specific regulatory guidance on these issues creates uncertainty that may inhibit adoption.
Commercial incentives. For incumbent banks, the commercial case for open banking is not always clear. Providing API access to competitors or disruptors may reduce competitive advantages without generating corresponding revenue. Some banks have adopted a selective approach, providing APIs for services that generate referral or transaction fees whilst restricting access to core banking data.
Screen scraping. In the absence of comprehensive API provision, some third-party providers use screen scraping — automated extraction of data from bank web interfaces using customer credentials. This practice raises security and liability concerns and is generally discouraged by banks, but the absence of alternative data access methods makes it difficult to eliminate entirely.
International Context
Switzerland’s market-driven approach to open banking stands in contrast to the regulatory mandates adopted in peer jurisdictions:
European Union. PSD2 requires banks to provide standardised API access to authorised third parties, with specific technical standards, authentication requirements, and response time obligations.
United Kingdom. The UK’s Open Banking Implementation Entity (OBIE) has developed and enforced detailed API standards, creating one of the most advanced open banking ecosystems globally.
Singapore. The Monetary Authority of Singapore has published API playbooks and encouraged voluntary adoption, a model more similar to Switzerland’s approach.
The Swiss financial centre’s competitiveness depends in part on its ability to offer services and capabilities comparable to those available in competing jurisdictions. As open banking matures in the EU and UK, Swiss institutions face pressure to provide equivalent capabilities to internationally mobile clients and fintech partners.
Outlook
Open banking in Switzerland is likely to advance gradually, driven by competitive dynamics, client expectations, and the strategic interests of both banks and fintech companies. The question of whether Switzerland will ultimately introduce regulatory requirements for open banking — perhaps influenced by the EU’s forthcoming Financial Data Access (FIDA) regulation — remains open.
For fintech companies, the Swiss open banking landscape offers opportunities for those that can navigate the fragmented API environment and build compelling applications on available data. For banks, the strategic question is whether to view open banking as a threat to be managed or an opportunity to enhance service offerings and client relationships.
