ABSTRACT This study examined the impact of the financial system with respect to banks and stock market on economic growth in Nigeria between 1991 and 2010. The debate among scholars on the comparative importance of banks and markets in promoting economic growth generated a lot of controversy. Some scholars argue that banks identify good projects, mobilize resources, monitor managers, and manage risk and so are better at promoting economic growth than the market. This gave rise to the bank-based financial system view. Others argue that the stock markets provide incentives for investors to acquire information, impose corporate control, and customdesign financial arrangements. According to these scholars, markets are better at promoting economic growth hence the market-based financial system view. In Nigeria, where its financial system comprises mainly banks and stock markets, focus has been on banks without adequate attention to the capital market. Policy makers tend to emphasize so much on banks in terms of reforms and individuals or companies depend so much on bank financing portraying Nigeria financial system as bank-based. With regard to this, the study sought to examine the bank-based and market-based financial systems and economic growth in Nigeria by assessing the impact of: (i) banks’ credit to private sector on economic growth in Nigeria, (ii) banks’ assets on economic growth in Nigeria, (iii) total value of shares traded on the stock exchange on economic growth in Nigeria, and (iv) market capitalization on economic growth in Nigeria. The ordinary least square method of analysis was employed to analyze the secondary data sourced from Central Bank of Nigeria Statistical Bulletin, Central Bank of Nigeria Annual Report and Statements of Account and Nigerian Stock Exchange Annual Reports and Statements of Account. Bank-based financial system proxied by banks’ credit to private sector and banks’ assets and Market-based financial system proxied by total value of shares traded and market capitalization served as the independent variables. Economic growth proxied by gross domestic product growth rate was used as the dependent variable. Results showed that (i) banks’ credit to private sector had a positive and significant impact on economic growth in Nigeria, (ii) banks’ assets had a positive and significant impact on economic growth in Nigeria, (iii) total value of shares traded had a positive and insignificant impact on economic growth in Nigeria, and (iv) market capitalization had a positive and significant impact on economic growth in Nigeria. These results showed that banks and market had positive impact within the period studied confirming the importance of both in promoting economic growth. The study therefore recommends that policy makers should make policies that will help develop both banks and market rather than focus on just one component of the financial system. Firms should be encouraged to raise long-term funds from the capital market rather than depend solely on bank financing.
