Abstract This study examines the long-term effect of lending rate, exchange rate, inflation, institutional regulatory quality, budget deficit and gross domestic product on financial sector stability, proxied by the behavior of bank credit from 1981 to 2018.

Although, in line with public good, financial institutions indeed have responsibility for the transmission of monetary policies and other financial functions, quality macroeconomic policies matter (North 1991; Knoop 2013). The same argument applies for policy failure, as it is rear to find a single cause for the financial system’s failure, but numbers of contributory factors (Ogunleye 2010; Heffernan 2005). Most studies in financial macroeconomic on Nigeria have explored the

financial system’s impact on macroeconomic volatility or the business cycle (Knoop 2008), while in studies on non-performing loans, many have studied idiosyncratic risk factors on non-performing loans (NPL) (Rajha 2016; Cantu´ et al. 2018).
