Operational resilience is a firm's ability to keep its most important services running for customers through severe disruption. For payment institutions and EMIs it has been a live legal obligation since 31 March 2025, the date by which every firm in scope had to be able to stay within its impact tolerances. The FCA's operational resilience framework, implemented through PS21/3, requires firms to identify their important business services, set impact tolerances and demonstrate that they can remain within those tolerances during severe disruption. For payment institutions, whose services are critical to customers and the wider economy, operational resilience is a regulatory priority. This article provides practical guidance for payment firms on meeting the FCA's expectations.
What Is Operational Resilience?
Operational resilience is the ability of a firm to prevent, adapt, respond to, recover and learn from operational disruptions. Unlike traditional business continuity planning, which focuses on recovering from incidents, operational resilience focuses on ensuring that important business services continue to be delivered to customers within acceptable parameters during and after disruption.
The FCA's framework is built on three pillars: identifying important business services, setting impact tolerances, and testing the firm's ability to remain within those tolerances.
Identifying Important Business Services
An important business service is a service provided by the firm to an external party (customers, market participants, the firm's counterparties) where disruption could cause intolerable levels of harm. For payment institutions, important business services typically include:
- Payment processing: the execution of customer payment transactions
- Safeguarding operations: the receipt, segregation and reconciliation of customer funds
- Customer onboarding: the ability for new customers to open accounts and begin using services
- Complaints handling: the ability for customers to raise and resolve complaints
- Customer access to funds: the ability for customers to see and withdraw their money
Firms should assess each service based on the potential harm that disruption could cause to customers, market integrity or the firm's own financial stability.
Setting Impact Tolerances
Impact tolerances define the maximum tolerable level of disruption to an important business service. They must be expressed in measurable terms, typically in terms of time, but potentially also in terms of the number of affected customers or the financial value of transactions impacted.
For payment processing, an illustrative impact tolerance might be expressed as: "Payment processing must be restored within 4 hours of a disruption, with no more than 2% of daily transaction volume affected." The specific tolerance will depend on the nature of the payment services provided, the customer base and the availability of alternative payment mechanisms.
Scenario Testing
Firms must conduct scenario testing to assess whether they can remain within their impact tolerances during severe but plausible disruption scenarios. Relevant scenarios for payment firms include:
- A cyber attack that disables the firm's core payment processing platform
- Failure of a critical third-party service provider (banking partner, technology vendor, cloud infrastructure provider)
- A major technology outage affecting multiple systems simultaneously
- Loss of access to a safeguarding bank account
- A sudden surge in transaction volumes beyond normal capacity
Scenario testing should involve all relevant teams, technology, operations, compliance, senior management, and should produce documented findings, identified vulnerabilities and remediation plans.
Third-Party Dependency Management
Payment firms are heavily dependent on third-party service providers: banking partners, technology platforms, cloud infrastructure providers, AML screening tools and customer verification services. The FCA expects firms to map these dependencies for each important business service, assess the risk of each dependency, and implement appropriate mitigations (contractual protections, alternative suppliers, manual fallback processes).
The Critical Third Party (CTP) regime, set out in PS24/16 and in force since 1 January 2025, lets the regulators oversee suppliers that the whole financial sector depends on. HM Treasury designated the first four CTPs on 10 July 2026, effective 13 July 2026: Amazon Web Services EMEA SARL, Google Cloud EMEA Limited, Microsoft Ireland Operations Limited and Oracle Corporation UK Limited. The regime places duties on those suppliers, not on their customers. Payment firms remain fully responsible for their own resilience.
Key Dates
| Date | Milestone |
|---|---|
| March 2021 | FCA publishes PS21/3, the operational resilience rules |
| 31 March 2022 | Firms identify important business services, set impact tolerances and begin mapping and testing |
| 1 January 2025 | CTP rules (PS24/16) take effect |
| 31 March 2025 | Firms must be able to remain within impact tolerances |
| 13 July 2026 | First four CTP designations take effect |
| 18 March 2027 | Incident reporting and third-party register rules (PS26/2) apply |
Under PS26/2, published on 18 March 2026, payment service providers must report significant operational incidents to the FCA. Authorised payment institutions and authorised EMIs must also keep a register of material third-party arrangements and submit it to the FCA every year.
What Firms Should Do Now
- Confirm your important business services and impact tolerances are still accurate, and record the annual review that SYSC 15A requires.
- Set measurable impact tolerances for each important business service.
- Map end-to-end processes including all dependencies and potential points of failure.
- Conduct scenario testing against realistic severe disruption scenarios.
- Develop and test remediation plans for identified vulnerabilities.
- Ensure the board receives regular reporting on operational resilience.

Frequently asked questions
Services provided to external parties where disruption could cause intolerable levels of harm, typically including payment processing, safeguarding operations and customer onboarding for payment firms.
The maximum tolerable level of disruption to an important business service, expressed in measurable terms such as maximum acceptable downtime.
SYSC 15A requires firms to review their important business services and impact tolerances whenever there is a material change, and in any event at least once a year. Scenario testing should support each review.
The CTP regime applies to designated suppliers, not to the firms using them. The first four, designated in July 2026, are major cloud providers. Payment firms must still manage those dependencies within their own operational resilience framework.
Yes. The FCA applies its operational resilience rules to firms authorised and registered under the PSRs 2017 and EMRs 2011, which includes small payment institutions and small EMIs. The work should be proportionate to the firm's size.
PS26/2 takes effect. Payment service providers must report significant operational incidents to the FCA, and authorised payment institutions and EMIs must keep a register of material third-party arrangements and submit it every year.
