Credit Cost
Credit Cost in banking is the provisioning expense — covering both specific provisions on non-performing assets and general or standard asset provisions — expressed as a percentage of average advances, and it is the single largest variable cost that separates a well-managed bank from a stressed one.
Credit cost, sometimes called provisioning cost or loan loss provision rate, captures what a bank sets aside in each period to absorb expected and unexpected losses embedded in its loan portfolio. RBI guidelines under the Income Recognition, Asset Classification, and Provisioning (IRACP) norms require banks to classify loans as Sub-standard, Doubtful, or Loss depending on the duration of the repayment breach, and to make minimum provisions ranging from 15% of Sub-standard loans to 100% of Loss assets.
The relationship between credit cost and the business cycle is well established. During economic expansions, credit costs are low because borrowers are servicing debt comfortably and new slippages — the flow of standard loans turning NPA — are minimal. Banks may even post provision write-backs (reversals of earlier provisions when recovered) that further reduce reported credit cost. During economic downturns, stress events, or sector-specific shocks, slippage rates spike and credit costs surge, sometimes dramatically compressing or eliminating net profits.
The 2015 to 2018 period illustrates this cycle in India: RBI's Asset Quality Review (AQR) initiated in late 2015 forced banks to reclassify restructured assets as NPAs, leading to a sharp and sudden escalation in credit costs for public sector banks. Several banks reported credit costs exceeding 3% to 4% of average advances, erasing years of retained earnings. The COVID-19 pandemic triggered another round of elevated provisioning in FY2020-21, though it was partially mitigated by RBI-mandated moratoriums and restructuring allowances.
Banks with robust underwriting standards, well-diversified portfolios, and strong risk management frameworks tend to maintain sustainable credit costs of 0.5% to 1.0% through cycles. Credit costs above 1.5% are generally viewed as elevated, while anything above 2.5% indicates significant portfolio stress. Analysts use credit cost alongside the Provision Coverage Ratio (PCR) to assess whether a bank is adequately reserved or is carrying an underprovided NPA book that could trigger future earnings shocks.
Credit cost also interacts with Return on Assets (ROA). A bank with a high pre-provision ROA can absorb elevated credit costs without turning unprofitable; one with a thin operating buffer cannot. This is why consistently high credit cost banks often trade at significant discounts to book value in equity markets — reflecting investor concerns about the underlying franchise's earning capacity net of provisioning obligations.
