This study empirically examines the vulnerability of the Nigerian banking industry to extreme, but plausible, adverse oil price shocks. A structural vector autoregressive (SVAR-X) is adopted to achieve this objective. The study period covers 2007Q1 – 2020Q4. The simulations assess the asset quality performance of DMBs, using the NPLs, under three scenarios (baseline, adverse and severely adverse). The findings suggest that the entire banking industry, as well as individual DMBs, are vulnerable to adverse oil price shocks. Accordingly, the study recommends, strict compliance with the single obligor limit, by commercial banks, to mitigate adverse effects of volatilities in crude oil prices. However, due to data limitations the study cannot extend the analysis, to the impact of oil price shocks, on the capital adequacy of DMBs. Consequently, the need for further studies on this issue cannot be overemphasised.
