SICR (Significant Increase in Credit Risk) is the IFRS 9 trigger that moves a financial asset from Stage 1 to Stage 2 of the expected credit loss model. Once SICR occurs, a bank switches from 12-month expected credit losses to lifetime expected credit losses. This happens even though the borrower has not yet defaulted.
Every bank reporting under IFRS 9 has to answer what is SICR credit risk in a way that satisfies its risk committee, auditors, and regulators. The stakes are real. Getting the SICR trigger wrong either delays loss recognition on deteriorating loans, or pushes performing loans into a much larger provision unnecessarily.
Understanding what is SICR credit risk matters beyond compliance, too. It shapes how much capital and provisions a bank sets aside, quarter to quarter, and how volatile those numbers look to investors and regulators.
Under IFRS 9, SICR is assessed by comparing two things. The first is the risk of a default occurring at the reporting date. The second is the risk of default at initial recognition of the financial instrument. This comparison sits in IFRS 9 paragraphs 5.5.9 to 5.5.11.
The standard does not hand banks a single formula for what is SICR credit risk in practice. Instead, it sets an objective: capture deterioration early. The methodology is left to each institution’s policy, subject to audit and regulatory review. This flexibility is deliberate. A retail mortgage book and a large corporate lending book deteriorate in very different ways, and a single rigid formula would fit neither well.
IFRS 9 groups every in-scope financial asset into one of three stages:
Almost every asset starts in Stage 1 at origination. It stays there as long as credit risk remains broadly stable.
Probability of default sits at the centre of the SICR test. The comparison is not simply “has PD gone up.” It compares lifetime PD at initial recognition with current lifetime PD, adjusted for the instrument’s remaining life.
When that comparison shows significant deterioration, the loan moves from Stage 1 to Stage 2. This changes two things at once. The ECL horizon shifts from 12 months to the full remaining lifetime. The PD used in the calculation shifts from a 12-month PD to a lifetime PD.
This is why PD estimation methodology and SICR policy cannot be built in isolation. A bank’s PD models feed directly into its staging decisions. An unstable or poorly calibrated PD model can push loans in and out of Stage 2 without any real change in the borrower’s risk. This adds unwanted noise to a bank’s provisions and earnings. For a detailed look at how banks build and validate these models, see our guide on PD Estimation Methods for Credit Risk: A 2026 Guide.
IFRS 9 asks banks to weigh quantitative and qualitative evidence together, rather than relying on a single metric.
Most banks set a relative PD deterioration threshold. A common example is a doubling or tripling of lifetime PD since origination, calibrated to the bank’s own portfolios. Some regulators publish additional guidance here. The European Central Bank, for instance, has recommended a threefold PD increase, a 12-month PD above 20%, or watchlist and forbearance status. These triggers apply to loans with an origination PD above 0.3%. They are supervisory expectations layered on top of IFRS 9, not requirements written into the standard itself. Banks outside the ECB’s direct supervision, including most Indian and Asian institutions, remain free to calibrate their own thresholds. They must simply be able to justify that choice to auditors and local regulators.
IFRS 9 paragraph B5.5.17 lists a wide range of qualitative signals to weigh alongside the quantitative test. These include changes in internal or external credit ratings, widening credit spreads, covenant breaches, deteriorating operating results, and expected forbearance. Paragraph B5.5.21 to B5.5.24 requires banks to consider these before relying on any single backstop.
IFRS 9 paragraph 5.5.11 sets a rebuttable presumption. If a borrower is more than 30 days past due, the standard presumes SICR has occurred, regardless of what other indicators show. A bank can rebut this presumption only with reasonable, supportable evidence that arrears past 30 days do not reflect a real increase in credit risk. Auditors test this evidence closely, since it is a high bar by design.
Consider a corporate term loan originated with a lifetime PD of 1.2%. At the next reporting date, updated financials and a rating downgrade push its lifetime PD to 3.5%, nearly a threefold increase. The bank’s SICR policy sets a relative-threshold trigger at a twofold PD increase for this exposure class. The loan crosses that threshold, so it moves from Stage 1 to Stage 2, even though the borrower has made every payment on time. The bank now measures ECL over the loan’s remaining life, rather than over the next 12 months, and books a correspondingly larger provision.
These three terms get confused often, but they mark different points on the same deterioration path.
SICR is a forward-looking signal. It flags that default risk has risen meaningfully, without claiming that default is imminent or has already happened. A loan in Stage 2, following a SICR trigger, may still perform fully. It simply carries a larger provision because its risk profile has worsened.
Credit-impaired, by contrast, means objective evidence of loss already exists. Examples include missed payments, restructuring under financial difficulty, or the borrower entering bankruptcy proceedings. Default, in most banks’ policies, aligns closely with the credit-impaired definition. It often follows Basel-style default definitions, such as 90 days past due. A Stage 3 asset has crossed this line. A Stage 2 asset has not.
For risk teams, this distinction has real operational weight. A SICR-only downgrade to Stage 2 should trigger heavier monitoring and a larger provision. It should not trigger the collections and recovery workflows reserved for default and credit-impaired accounts. Conflating the two stages in internal reporting is a common source of confusion between risk, finance, and collections teams.
Three problems recur across banks working through what is SICR credit risk in practice. First, threshold calibration: a threshold set too tight moves loans between stages on ordinary risk fluctuations, adding earnings volatility without adding insight. A threshold set too loose delays recognition of real deterioration, understating provisions when it matters most.
Second, PD model stability matters just as much as threshold calibration. Since the SICR test compares PD at two points in time, any noise or drift in the PD model translates directly into staging noise. This happens even when nothing about the borrower has actually changed. Getting comfortable with the full stage-classification and ECL workflow, not just PD in isolation, is what separates a defensible SICR policy from a fragile one — our Advanced Certificate in IFRS 9 Modeling walks through this end to end.
Third, procyclicality. SICR thresholds often respond to forward-looking economic assumptions. A downturn in the macroeconomic outlook can push large numbers of loans into Stage 2 at once, even before individual borrower behaviour changes. A sudden jump in Stage 2 balances can otherwise look like a portfolio quality problem, rather than an expected model response. Risk teams need to explain this pattern clearly to stakeholders who are not modelling specialists.
Is SICR the same as default?
No. SICR signals a meaningful rise in default risk and moves a loan to Stage 2 with lifetime ECL. Default, or credit impairment, is a later, more severe stage with objective evidence of loss.
What happens if a loan no longer shows SICR?
IFRS 9 allows a loan to move back from Stage 2 to Stage 1. This requires evidence that the significant increase in credit risk no longer exists. The 12-month ECL basis is then restored.
How often should SICR be reassessed?
IFRS 9 requires SICR assessment at each reporting date, not just at origination. Most banks run this assessment monthly or quarterly, aligned to their broader ECL reporting cycle, so staging stays current with the latest available data.
