The objective of the paper is to assess the effects of foreign portfolio capital surge on the banking sector in Nigeria from 2005 - 2018. Using a simple trend analysing a static general equilibrium framework, the paper reveals that portfolio capital inflows, in the wake of monetary policy independence in Nigeria, led to portfolio capital surge which resulted to credit boom and speculative transactions in the Nigerian Stock Exchange (NSE) leading to assets price bubble. When the bubble burst during the global financial crisis (GFC) in 2007, and thereafter in 2014, portfolio capital inflows reversed and banking stocks prices declined sharply. This contributed to the high level of banks' nonperforming loans (NPLs). The rise in NPLs resulted to poor assets quality of the banks which contributed significantly to banking crisis in Nigeria. Based on these findings, the paper recommends that CBN should review upward the existing macro-prudential regulations in addition to taking some portfolio capital inflows control measures to reduce banking crisis and promote banking stability in Nigeria
