Strengthening resilience for a machine-speed world
Banks face three converging resilience challenges heading into 2027: Cyber threats are outpacing remediation cycles, forcing banks to move faster; operational resilience frameworks need rethinking; and the regulatory shift toward principles-based risk management.
Accelerating cyber remediation
Some banks have moved to address cyber risks from Frontier AI models, but the work is in progress. As AI adoption expands vulnerabilities and increasingly capable frontier and open-weight models equip adversaries just as quickly, cyber efforts will likely remain a priority for banks in 2027.
They should focus on four fronts: prioritize vulnerabilities based on exploitability and business impact, automate low-risk remediation, deploy compensating controls while fixes are underway, and enable faster decisions without weakening oversight.33 However, few banks have the in-house engineering capabilities to implement these measures alone, making third-party alliances important to help bolster cyber defense.
Rebuilding resilience for a different kind of failure
Many banks have built resilience capabilities over the past decade. But today’s threats, dependencies, and speed of disruption require those capabilities to evolve to address a very different set of risks.
Many banks have mature testing programs. But mature testing does not always mean real-world readiness. Some tests demonstrate compliance rather than how systems, teams, and third parties may respond to a live disruption. Banks should implement realistic exercises, continuous validation, and fast feedback loops.
Accountability should be stronger. Cyber incidents require a coordinated response across technology, operations, business continuity, and risk, with clear decision rights, handoffs, and escalation paths. Senior management and the board should remain accountable for the overall response.
Many banks have immutable backups, yet coverage of critical systems and recovery testing can still fall short. Banks should focus backup investment on the systems that matter most and test their recovery capabilities before an actual incident occurs.
AI adoption is moving faster than governance. Heavy reliance on a small group of models and vendors can create shared points of failure across banks. Managing this concentration risk, model access, and data lineage should be a core resilience priority.
Redefining the three-lines model
US regulators appear to be giving banks more flexibility in how they manage risk while holding them accountable for resilience across their full ecosystem, including third parties.34 This more principles-based approach can allow institutions to build scalable risk-management frameworks suited to their operating models and risk profiles.35
Under this tailored approach, business owners in the first-line function embed risk management into day-to-day operations. Second-line teams, including risk, compliance, and control functions, focus on enterprise exposure, challenge key decisions, monitor outcomes, and target independent testing rather than re-verifying the same controls.
Internal audit, as the third line, serves as an independent validator of regulatory remediation and provides rigorous challenge to the first and second lines. It should also take a forward-looking view, helping assess changes to risk frameworks and identify emerging risks early.
Examiners are raising the bar for what warrants a formal finding, with greater focus on financial materiality than issue volume. Banks that proactively identify and remediate issues before examinations may be better positioned to stay ahead of supervisory expectations.
Bold choices for a new era
Banks will likely be challenged by uneven growth in 2027. Corporations and AI firms could fuel business, while consumer demand may become more muted. In this environment, banks may need to be selective about capital deployment, AI investments, and growth areas.
A question for bank leaders to consider is how to turn investments into durable advantage. AI is increasingly transforming banks’ businesses, as well as the broader economy, and digital assets are playing a role in reshaping financial infrastructure. Banks that can convert capital and technology investment into growth, while strengthening resilience along the way, may be well positioned to pull ahead in 2027.
