Series introduction<\/strong><\/p>\n

The first blog in this series argued that SR 26-2 does not simply reduce the model risk management burden. Instead, it places greater responsibility on banking organizations to make, support, and defend risk-based judgments.<\/p>\n

This second blog examines where that shift creates operating-model flexibility\u2014and the policy, governance, and control boundaries that remain.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

The room is real, but it is bounded<\/h1>\n

SR 26-2<\/a>\u00a0creates real room for firms to rethink parts of their\u00a0model risk<\/a>\u00a0operating model. But the room is smaller and more conditional than the initial reaction to the guidance may suggest.<\/p>\n

The most important areas of flexibility are threefold: a named path for immaterial models, the removal of\u00a0SR 11-7<\/a>\u2019s guidance-level annual review cadence, and a narrower definition of what qualifies as a model. Each creates potential efficiency. None eliminates the need for control.<\/p>\n

Immaterial models now have a named lighter path<\/h1>\n

SR 26-2 introduces the idea of an immaterial model and says that, for those models, model risk management can consist of identifying them and monitoring for the conditions under which they could become material. This is a genuine lighter-touch path that the guidance states outright, not something banks have to infer from its shorter length.<\/p>\n

This matters because it gives firms an explicit basis to avoid applying heavy model risk machinery to models that do not warrant it. But it also raises the burden on classification. A model can only travel the lighter path if the firm can defend why it is immaterial and how it will know if that status changes.<\/p>\n

The annual cadence has been loosened, not eliminated<\/h1>\n

SR 26-2 also drops SR 11-7\u2019s \u201cat least annually, more frequently if warranted\u201d review cadence. In its place, validation timing and frequency vary by model purpose, methodology, frequency and scope of changes, and data limitations.<\/p>\n

For a\u00a0stable, well-performing model<\/a>\u00a0that has not changed, the guidance no longer imposes an annual full revalidation minimum. That opens the door to trigger-based revalidation: revalidate when there is a material change, a performance breach, or a regime shift, rather than simply because the calendar turned.<\/p>\n

Two boundary conditions keep this honest. First, removing the guidance-level annual minimum does not mean stable models need no periodic revalidation. It means SR 26-2 no longer fixes the interval. A firm\u2019s own model risk policy, regulatory capital rules, and other applicable requirements may still impose periodic validation independent of SR 26-2. Any savings are bounded by those requirements, not by SR 26-2 alone.<\/p>\n

Second, SR 26-2 narrows the definition of \u201cmodel\u201d itself, explicitly excluding simple spreadsheet arithmetic and deterministic rule-based processes and software. That is a legitimate scope reduction, and firms should audit their inventories for it. But anything with statistical, economic, or financial theory underneath it stays in.<\/p>\n

A tool can leave the model inventory without leaving the risk inventory<\/h1>\n

The narrower model definition should not be confused with the disappearance of risk. A spreadsheet that no longer meets the definition of a model is still a spreadsheet that can be wrong. If a tool is de-scoped from the model inventory, it needs a control home\u2014for example, an end-user computing program or equivalent framework.<\/p>\n

Otherwise, the institution has not reduced risk. It has moved risk off the model-risk ledger and into a place that may be harder to see.<\/p>\n

The $30 billion point changes emphasis, not obligation<\/h1>\n

One scope point deserves precision. SR 26-2 says it is expected to be most relevant to banking organizations with more than $30 billion in total assets, and that smaller organizations are generally outside its focus.<\/p>\n

This does not leave smaller banks ungoverned. SR 11-7 has been rescinded for all firms, and a sub-$30 billion organization is now expected to run model risk management appropriate to its size and risk profile. SR 26-2 itself notes that its principles may still be relevant to a smaller organization whose model use is prevalent, complex, or extends beyond traditional community banking.<\/p>\n

The threshold changes supervisory emphasis, not the basic obligation to manage model risk. The wording itself signals as much: the guidance uses hedged terms such as \u201cmost relevant\u201d, \u201ctypically\u201d, and \u201cgenerally\u201d, rather than a clean cutoff. That is a fair indication that the $30 billion figure marks a shift in supervisory focus, not a bright line a smaller bank can stand behind.<\/p>\n

Review does not equal validation<\/h1>\n

One change won more approval from practitioners than almost any other: dropping the fixed annual cadence. The reason lies in how the old rule drifted in the field. SR 11-7\u2019s \u201cannual review\u201d language was originally meant to describe a lighter-touch check, a look at a model\u2019s performance and a few related indicators. But over time, many examiners came to treat it as a call for full annual validation, a much heavier exercise. In practice, the two ideas often merged.<\/p>\n

By tying frequency to a model\u2019s purpose, methodology, and materiality, SR 26-2 gives firms room to separate them again and right-size the lighter work.<\/p>\n

A more disciplined operating model<\/h1>\n

The practical operating model follows from that distinction. Rather than revalidating the whole inventory every year, a firm can lean on\u00a0ongoing monitoring<\/a>\u00a0for stable models and rotate the heavier\u00a0validation<\/a>\u00a0work across its higher-risk population on a multi-year cycle.<\/p>\n

Industry reporting suggests some firms are doing roughly this\u2014revalidating a portion of their higher-risk models each year rather than the whole set annually\u2014though the right fraction and cycle length depend on the inventory, not on any figure in the guidance.<\/p>\n

The effort that frees up should be redirected to genuinely complex models and hard-to-model areas where\u00a0automated testing<\/a>\u00a0cannot substitute for expert review. The point is not to do less. It is to stop spending heavy-validation effort on models that have not changed and carry little risk.<\/p>\n

The bottom line<\/h1>\n

SR 26-2 creates flexibility, but not a free pass. The best firms will use the guidance to reallocate effort, not to weaken discipline: lighter treatment for immaterial models, trigger-based revalidation for stable models where permissible, better inventory hygiene, and stronger focus on the models that genuinely move P&L, capital, or regulatory outcomes.<\/p>\n

The operating opportunity is real. It is just conditional on evidence, policy alignment, and a defensible materiality framework.<\/p>\n
