Banking sector reforms is the deliberate policy measures adopted by the monetary authority to promote the safety, soundness, reliability and stability of the sector, in order to be able to deliver the expected goods by improving the economy. It is against this background the investigates that impact of bank sector reforms on Nigeria's economics growth for the period which spanned from 1970 to 2014 using ARDL analysis. The period study was disaggregated into pre bank reforms period (1970-1985), reforms period (1986-2014) and pool period (1970-2014). Real Gross domestic product (GDP) was used as a proxy for economic growth regressed on some bank performance variables such as ratio of narrow money to broad money, loan deposit ratio, commercial bank credit to the private sector, cash reserve ratio and interest rate. The study found that the bank reformed has not impacted on the growth of the Nigerian economy. The study recommend that the government should ensure strict regulatory measures through the use of its monetary policies to regulate the banking sector and the Central Bank of Nigeria should continue with its banking sector reforms and encourage substantial credit allocation to the prioritized private sector.

This study employs Error Correction Model (ECM) and Co-integration analysis to study the relationship between financial sector development and savings mobilization in Nigeria 1986 to 2017. As expected from a developing country like Nigeria, a short-run positive relationship is observed between the Nigerian stock market and crude oil prices and the direction is from crude oil prices to the Nigerian stock market but not the other way round. The short run, interest rate earning has a positive and significant impact on domestic savings while the other variables have no significant impact domestic savings in Nigeria. Government should therefore consolidate on past financial sector reforms to improve domestic saving mobilization to reduce the dependence of Nigeria on foreign savings to finance domestic investment.
