CBN Demands Bank Stress Tests as Liquidity Hits N61tn
The Central Bank of Nigeria (CBN) has ordered all commercial banks to undergo rigorous stress tests starting April 1, 2026. This directive arrives as the industry enters the final stretch of its recapitalisation journey, with a March 31 deadline for meeting new capital floors. The apex bank intends to measure how lenders would survive “extreme economic conditions,” including severe recessions or market crashes. Any capital shortfalls identified during these tests must be covered by 100% within 18 months, effectively extending the fundraising cycle for weaker institutions.
The timing of the order highlights a paradox in the Nigerian financial system: banks are flush with cash but hesitant to lend. In February alone, banks deposited a staggering N61.1 trillion with the CBN through the Standing Deposit Facility (SDF)—a 16.2% increase from January. This mountain of idle liquidity suggests that while banks have the “firepower,” they prefer the modest, risk-free returns of the central bank over the volatile credit markets of the wider economy.
The stress tests will be uncompromising on “insider-related” risks. In a letter dated March 6, the CBN directed that all loans linked to bank directors or insiders be treated under a “severe stress assumption” and assumed to be in default. This move aims to expose governance rot and ensure that capital adequacy ratios (CAR) are not artificially inflated by questionable internal lending. Banks must simulate a 12-month deterioration in their credit portfolios, accounting for shocks like crashing commodity prices or further naira depreciation.
The regulator is particularly concerned with “stage migration”—the process where healthy loans slide into “substandard” or “lost” categories. If a bank’s internal data shows signs of industry-wide trouble, the CBN has mandated an additional 10% provisioning buffer. This “forward-looking” supervision is designed to prevent a repeat of past banking crises where thin capital cushions were evaporated by sudden market shifts. Lenders are now required to report both their pre-stress and post-stress capital positions to the apex bank for verification.
Market analysts view the N113.7 trillion deposited with the CBN in the first two months of 2026 as a sign of deep-seated caution. While the system is undeniably liquid, investment banker Tajudeen Olayinka notes that elevated benchmark interest rates make the “safety” of the CBN window more attractive than aggressive credit expansion. The upcoming stress tests will likely force this idle capital into the spotlight, revealing which banks are truly resilient and which are simply hiding behind the regulator’s balance sheet.
The results of these tests will set the “risk-based capital requirement” for each bank for the next cycle. By linking capital needs to specific risk profiles rather than just flat industry minimums, the Olayemi Cardoso-led CBN is moving toward a more sophisticated, global standard of regulation. For the 30 banks that have already hit their recapitalisation targets, these tests are the final exam; for the laggards, they may well be a final warning.
