Who's liable when an open banking third party fails

Formal liability for an open finance failure sits with the Account Information Service Provider (AISP), the Payment Initiation Service Provider (PISP), or whichever party a data access agreement names -- but the account-holding financial institution is still the one that must respond to the customer first, absorb the immediate cost, and only afterward pursue redress from the rest of the chain. Treating the named legal party as the practical safety net overlooks that sequence entirely: an institution can be contractually covered and still be first in line to pay.

To close the gap between formal and practical liability, financial institutions should structure their approach around four connected steps:

1. Map the practical liability sequence: Identify, before an incident occurs, that the institution will need to make the customer whole immediately regardless of what the data access agreement says about the AISP or PISP named as formally liable.
2. Verify beyond the named counterparty: Extend visibility past the direct AISP or PISP relationship to the participants further down the chain, since practical failures may originate several steps removed from the named party.
3. Monitor continuously, not at renewal: Replace static, point-in-time contract review with ongoing visibility into the full open finance chain, so risk is tracked as it changes rather than annually.
4. Price the redress gap: Quantify the time and cost of pursuing recompense from the chain after making a customer whole, so the practical liability position -- not just the legal one -- is reflected in how the relationship is risk-rated.
