Operational resilience has become one of the defining challenges in investment management. Methods for anticipating, absorbing, and adapting to disruptive events have been shaped mainly by the largest financial institutions. Today, however, the pressure has widened. Mid-market investment firms face many of the same disruption risks and rising expectations, but they do not have the same margin for error.
That mismatch is becoming harder to ignore. The modern resilience standard has evolved to become more than a continuity binder, a set of backups, or a disaster recovery plan that works in theory. Financial authorities increasingly frame operational resilience around a firm’s ability to keep important business services running through disruption and to prevent, adapt to, respond to, recover from, and learn from operational incidents.
For mid-sized investment firms, that raises a more difficult question than whether some controls exist: can the firm actually sustain critical operations under pressure, and can leadership prove it can do so?
The changing conversation around operational reslience
Operational resilience has evolved from a mostly technical issue into a broader business function. It now sits at the intersection of technology, operations, governance, vendor management, and leadership accountability.
This is because operational risks and disruptions have not only changed but also become broader in scope. In practical terms, resilience is about what happens when markets are open, clients need answers, workflows are time-sensitive, and a cyber event, system outage, or third-party failure hits at the wrong moment.
The larger point is that resilience extends beyond whether a firm can restore technology eventually. It is judged more by whether the firm can keep important business services within acceptable levels of disruption. That shifts the conversation from infrastructure ownership to service continuity, from technical recovery to business impact, and from documentation to evidence.
Why mid-market firms are more exposed
Leaders at mid-market firms are not indifferent towards operational resilience. In most cases, they understand the stakes quite clearly. The problem is that they are trying to meet modern resilience expectations with operating models that were built for a less demanding environment.
Lean internal teams are one reason. Many mid-sized firms do not have the luxury of dedicated resilience functions, large enterprise architecture groups, or separate teams focused solely on testing, mapping, and incident preparedness. Responsibility is often spread across infrastructure, operations, compliance, security, and outside providers. Everyone touches part of the problem, but no one necessarily owns the full picture.
Budget pressure matters too, but not in a simple way. Resilience investments compete with modernization, cybersecurity, trading support, data initiatives, and growth priorities. In that environment, a firm may improve one area without addressing whether critical services can continue through a severe but plausible disruption.
This is where the gap between large institutions and mid-market firms starts to widen. McKinsey argues that leading financial firms are approaching operational resilience through actions that link risk management to business impact and upgrade governance. They are building resilience capabilities and investing in data and tooling more intentionally. Mid-market firms often recognize those same needs, but they cannot pursue them at the same speed or scale. As a result, resilience can remain a patchwork of controls rather than a coordinated discipline.
The four gaps that matter most
When mid-market firms struggle with resilience, the problem usually does not begin with one catastrophic weakness. More often, it shows up as a collection of smaller gaps that become dangerous when a disruption forces the firm to act quickly.
I. Defining critical business services
One common gap is incomplete clarity around important business services. Firms usually know their critical applications, but that is not the same as defining the business services that must continue during disruption. Trading support, NAV-related workflows, investor reporting, reconciliations, cash movement, and communications may all depend on overlapping systems, teams, and vendors. If those service relationships are not clear, priorities can become confused at exactly the wrong moment.
II. Weak dependency mapping
A second gap is weak dependency mapping. The Bank of England’s operational resilience framework emphasizes that firms should:
- Identify important business services and set impact tolerances.
- Map the people, processes, technology, facilities, and information that support those services.
- Test whether they can remain within those tolerances during severe but plausible disruptions.
Mid-market firms often do some of this work, but they may do it unevenly. They may know the main platform dependencies. However, they may lack visibility into manual workarounds, privileged access paths, or the specific third parties whose failure would stall service delivery.
III. Overly optimistic assumptions
A third gap is that recovery assumptions are often more optimistic than tested. Firms may have continuity plans, recovery targets, and vendor commitments on paper. But unless those assumptions are exercised under realistic conditions, they can remain conceptual. A plan that looks reasonable in policy form can break down quickly if decision rights are unclear, cross-functional communication is slow, or a provider cannot support the firm at the expected pace.
IV. Fragmented accountability
A fourth gap is fragmented accountability. Security may focus on threats. Infrastructure may focus on uptime. Operations may focus on process continuity. Compliance may focus on policies and evidence. Without a unifying operating model, the firm can have active work in each area while still lacking a coherent resilience posture.
Risks and outcomes of low operational resilience
FINRA’s 2026 Annual Regulatory Oversight Report reinforces a broader pattern in financial supervision: firms are expected to actively review risks, tailor controls to their business models, strengthen supervisory procedures, and incorporate findings and effective practices into their programs in ways that reflect their size and activities. That points away from one-time resilience preparation and toward a more living model of oversight, testing, communication, and adjustment.
The business implications are just as important as the compliance implications. During a disruptive event, leadership cannot afford ambiguity over what must be restored first, which provider owns the problem, what workaround is viable, or whether the disruption is already exceeding acceptable thresholds for client service or market activity.
This is one reason operational resilience is becoming a competitive capability as much as a defensive one. Clients, counterparties, and internal stakeholders care less about which tools a firm has bought and more about whether it can operate with stability when conditions are unfavorable.
What a realistic catch-up path looks like
The catch-up path for mid-market investment firms does not involve copying the infrastructure depth of the largest institutions. That is rarely realistic, and it is often unnecessary. The better path is more selective:
- Narrow the resilience conversation to the services that matter most. That means identifying the business services whose disruption would create unacceptable client harm, control failure, or operating stress. Once those services are defined, the firm can be more disciplined about where to focus mapping, testing, and investment.
- Adopt a clearer governance model. McKinsey’s framing is useful here. It treats resilience as something that must be connected to business impact and supported by governance and capability-building, rather than managed as a loose collection of technical safeguards. Mid-market firms do not need elaborate committee structures, but they do need ownership that is visible, consistent, and connected to business decisions.
- Enable realistic testing. That means moving beyond annual checkbox reviews and using targeted scenario exercises and recovery validation to see where assumptions fail. The biggest value often comes from discovering where communication, escalation, or vendor coordination breaks down.
- Improve resilience evidence as capabilities improve. The Bank of England highlights the role of operational resilience self-assessments in helping boards and senior management understand vulnerabilities, remediation strategies, and investment timelines. Mid-market firms benefit when resilience work is documented in a way that supports better prioritization.
Where leaders should focus first
For leadership teams, the fastest resilience gains often come from reducing ambiguity:
- Identify critical business services. If the organization cannot state which business services matter most, resilience work will remain too broad and too reactive. Important services should be defined in business language, not just in terms of applications or infrastructure.
- Build one accountability model. Resilience crosses technology, operations, security, compliance, and third parties. That makes shared responsibility inevitable, but it should not mean unclear ownership. Someone needs to be accountable for joining the pieces together and turning operational resilience into an operating discipline.
- Test coordination, not just recovery. Technical recovery matters, but many failures occur in decision-making, escalation, and sequencing. Tabletop exercises and cross-functional scenarios can expose those weaknesses sooner and more affordably than waiting for live incidents to do the work.
- Treat evidence as part of the capability. Resilience is easier to improve when the firm can show where it is strong, where it is exposed, and what it is fixing. Evidence should be part of how the organization learns and prioritizes.
The firms that catch up will think differently
Mid-market investment firms do not need enterprise-scale redundancy everywhere. They do need a clearer view of their important services, a more realistic understanding of dependencies, and a stronger habit of testing and proving readiness. The firms that make those shifts will be better positioned to absorb disruption, satisfy rising expectations, and grow without carrying operational fragility into the next phase of the business.
