TL;DR
OpenAI’s May 15 US personal-finance rollout, described in the source material as using Plaid access across more than 12,000 institutions, highlights why a similar European launch would be harder. In the EU, bank-data access, wider financial-data access and credit-related AI are governed by overlapping licensed and supervised regimes.
OpenAI’s personal-finance surface launched in the United States on May 15 using account connections through Plaid, but the same model would face a different legal path in Europe, where access to bank and financial data is regulated through licensed, consent-based regimes and AI rules can apply when systems affect credit decisions.
The source material says the US product relies on Plaid connections across more than 12,000 institutions and treats read-only financial aggregation as a private access layer. It says that approach does not map cleanly to the EU, where payment-account access has been regulated under PSD2 since 2018.
The next phase of EU payment rules, the Payment Services Regulation and Third Payment Services Directive, reached provisional agreement on November 27, 2025, according to the source material. Final texts are expected in the Official Journal in 2026, with core duties expected across 2027. The source frames this as a move from private aggregation toward a directly applicable EU rulebook for account access and API quality.
The source also points to the proposed Financial Data Access regulation, known as FIDA, as the wider open-finance layer. FIDA would extend access rules beyond payment accounts to areas such as investments, pensions, insurance, mortgages and loans, and would create a Financial Information Service Provider license for firms handling that data. The source says FIDA was still in trilogue as of April 2026, with likely operating dates around 2029 to 2030.
Why It Matters
The development matters because it changes who can build conversational finance tools for European users and how they can be built. A US-style interface can be shipped on top of private data-aggregation deals. In Europe, the source argues, the legal architecture comes first: the license, consent flow, API controls and AI classification shape the product before the chat interface reaches users.
That could favor banks, regulated fintechs, open-banking providers and firms already built around supervisory obligations. It may also slow market entry for large AI companies if their products depend on broad access to a user’s full financial life.

Background
PSD2 made payment-account access a regulated activity in the EU in 2018. The pending PSD3 and PSR package is meant to update that system, including stronger rules around access interfaces and supervision.
FIDA would broaden the model from open banking to open finance. Its details remain politically and commercially sensitive, including the proposed data-access fee described in the source material as a contested point.
The EU AI Act adds another layer. The source says AI systems used for credit scoring and creditworthiness assessment are classed as high-risk, with full obligations due on August 2, 2026. For financial-services systems, supervision may fall to financial regulators such as Germany’s BaFin rather than a general technology regulator.

What Remains Unclear
Several details remain unsettled. The final PSD3 and PSR texts had not yet appeared in the Official Journal in the source account. FIDA was still in trilogue as of April 2026, and its timing, licensing mechanics and data-access fee may still change. It is also unclear how a specific conversational-finance product would be classified under the EU AI Act unless its functions, outputs and use in credit-related decisions are known.

What’s Next
The next milestones are the final publication and implementation timetable for PSD3 and PSR, the outcome of FIDA negotiations, and the August 2, 2026 start of full EU AI Act obligations for high-risk systems. Any company seeking to bring a US-style conversational-finance product to Europe would need to map licensing status, consent design, data-access routes and AI-risk classification before launch.

Key Questions
What happened?
OpenAI’s US personal-finance surface is being used as a test case for why a similar conversational-finance product would face a different regulatory path in Europe.
Why can’t the US model simply be copied in Europe?
The source material says US account aggregation can rely on private access layers such as Plaid, while EU access to bank and wider financial data is tied to licensed, consent-based and supervised regimes.
What EU rules are involved?
The main regimes cited are PSD2, the planned PSD3 and PSR package, the proposed FIDA open-finance regulation, and the EU AI Act for credit-related AI systems.
Does the EU AI Act ban conversational finance products?
No. The source does not say the products are banned. It says obligations may rise if a system is used for credit scoring or creditworthiness assessment, which the EU AI Act treats as high-risk.
Who may be best placed to build this in Europe?
The source argues that firms already designed around financial regulation, consent handling and licensed data access may have an edge over companies that won in the US through private aggregation layers.
