Hypothetical example: On a Monday morning, the head of digital at a German regional bank reads that ChatGPT can now read bank accounts for every user in the US. Her board asks whether, two years from now, the bank's own app will still be where customers think about their money. She has to decide whether to wait until the feature reaches Europe or to invest in the bank's own assistant now. The question behind it is bigger than a new feature.
When ChatGPT reads the bank account, the bank risks becoming a background provider: it still runs the account, but the conversation about money happens somewhere else. This article sets out what has happened in the US, which routes lead to Europe and where banks still hold the advantage.
At a glance
Since October 2026, ChatGPT has been able to read connected bank accounts for all users in the US, but it cannot move money.
In the EU, this kind of account access requires customer consent and a registered account information service under PSD2; no EU launch date has been announced.
A bank's lever is its richer context and its licence to act, not access to account data alone.
What happened: ChatGPT reads the bank account
In 2026, OpenAI rolled out a finance feature in stages that lets US users connect their accounts to ChatGPT and have them analysed. Access is read-only and so far limited to the US.
On 15 May 2026, OpenAI launched a preview for Pro users in the US. Accounts are linked through the data aggregator Plaid, with support for more than 12,000 financial institutions at launch (OpenAI). Plus and Pro users got access on 25 June, and Free and Go users in the US followed on 2 October 2026 (OpenAI).
ChatGPT can see balances, transactions, investments and liabilities. It cannot see full account numbers or make any changes to accounts (OpenAI). Transfers, bill payments, trades and account openings are off the table. OpenAI has not published a date for any other country (MIXED).
Three scenarios for Europe
Whether and how such a feature reaches Europe depends less on technology than on the legal framework for data access. Three routes are conceivable, and they are not mutually exclusive.
Under the Payment Services Directive PSD2, an account information service is an online service that consolidates information on a customer's payment accounts held at one or more banks; it must be registered and needs the customer's explicit consent (EUR-Lex, Directive (EU) 2015/2366).
Scenario | Route to Europe | What it means for banks |
|---|---|---|
1. Wait and see | Feature stays US-only; customers upload statements themselves | Little pressure, but people get used to AI conversations about money |
2. PSD2 route | Partnership with a registered account information service | Access to payment accounts is possible without new legislation |
3. Open finance | Broader data access under the planned FiDA regulation | Savings, investment and credit data would also be covered |
Its successor, PSD3 together with the Payment Services Regulation (PSR), has been agreed politically: Parliament and Council reached a provisional agreement on 27 November 2025, and formal adoption is still pending (European Parliament). FiDA, by contrast, has stalled: the last trilogue round took place in June 2025 (Deloitte). That makes scenario 2 the shortest path.
The bank's context advantage
A language model with read access sees numbers; the bank knows the relationship behind them and is allowed to act. That advantage only holds if the bank actually uses it.
The model does have a real strength: it sees accounts at several banks at once and sits where people already ask their questions. The bank, however, knows terms, maturities, consents, past conversations and complaints. Above all, it can act: initiate a payment, adjust an overdraft, roll over a term deposit. As of 2 November 2026, the language model cannot (OpenAI).
A bank that turns this context into a conversation inside its own app removes the reason to connect the account elsewhere. Our article on the banking app as a financial hub describes how such an assistant is built on one data loop. What customers would hand to a bank assistant first is covered in our analysis of a TD survey.
What banks should do in 2027
Banks should turn their context advantage into their own AI conversations now, before customers get used to someone else's. Four steps are enough to start.
Prioritise your own assistant: answer the most frequent questions about accounts, transactions and contracts in the app, with reasoning and source.
Link actions to approval: where the bank can trigger something, offer the step in the conversation, confirmed by the customer.
Manage data access: track PSD2 interfaces, consents and third-party access closely; they show where customers are sending their data.
Make trust visible: explain hosting, data protection and audit reports openly. According to the Visa study on AI in banks, trust is an investment goal in its own right.
ACCELERAID supports banks with an AI Assistant and a personalization layer that work on the bank's own customer context. The platform follows GDPR by design, runs in an ISO 27001 data centre in Frankfurt or on-premises on request, and is independently audited against SOC 2 (ACCELERAID).
Frequently asked questions
Can ChatGPT already access bank accounts in Europe?
No. According to OpenAI, ChatGPT's finance feature is only available in the US, for Free, Go, Plus and Pro users. No date has been announced for Germany or any other EU country. In the EU, account access would require the customer's consent and a registered account information service under PSD2.
Can ChatGPT make bank transfers?
No. As of 2 November 2026, access is read-only. ChatGPT sees balances, transactions, investments and liabilities, but not full account numbers. According to OpenAI, it cannot make changes to accounts; transfers, payments, trades and account openings are excluded. This is exactly where the bank, which may execute instructions within a conversation, holds an advantage.
What does disintermediation mean for banks?
Disintermediation means a third party inserts itself between the bank and its customer. The bank still runs the account and products, but advice, comparison and decisions happen in someone else's interface. For banks, this reduces visibility, advisory moments and cross-selling, even if the account relationship formally remains in place.
