In every developing and developed economy, the capital market has been identified as an institution that drives growth and development. The capital market is a conduit for the demand and supply of debt and equity capital then channel funds to firms with relatively high and increasing productivity thus, enhancing economic expansion (Donwa, 2010). Capital market provides a means through which a nation gets the local and foreign investment it needs for sustainable growth and development.
Capital market offers varieties of financial instruments that enable economic agents to pool price and exchange risks through assets with attractive yields, liquidity and risk characteristics (Nwakwo 1991). The financial crises which started in the United States (due to certain laxities in the US financial system), spread to Europe and has become global. Even countries not affected by the crises before are now affected by second round effect (CBN 2009).
Olawale (2015) revealed that stock markets across the globe have been severely affected by the current financial crises ravaging the global economy. This resulted in large loses recorded by these markets since second half 2008 and volatility, making the markets unstable over the years. Yahaya et al. (2011) posited that the financial meltdown impacted negatively on the operational performance and efficiency of the Nigeria stock market. The Nigeria stock market has witnessed volatility over time.
Stock market volatility is a measure for variation of price of a financial asset overtime.it is essentially concerned with the dispersion and not direction of price changes. Issues of volatility in stock market behavior are of importance as they shed light on the data generating process of the returns (Hongyu & Zhicha, 2006) as a result, such issues guide investors in their decision making process because not only are the investors interested in returns but also in uncertainty of such returns. A volatile stock market weakens consumer confidence and drives down consumer spending (Porteba, 2000). The author further indicated that it affects business investment because it conveys a rise in risk of equity investment. This can alter investment equilibrium position of an economy as investors turn to purchase stocks of larger well known firms at the expense of new firms. It can trigger a general rise in cost of capital and directly affect economic growth. Investor’s portfolio allocation would be affected as they would have to hold more stocks in their portfolio in order to reap the benefits of diversification (Frimpong & Oteng-Abaiye 2006)
The positive linkage school of thought has it in view that a well-functioning capital market will precipitate long term economic growth (Alile 1984; Atje & Jovanovich 1993; Oyijide 1994). The opposing school of thought however believes that the alleged positive linkage between capital market development and economic growth is not proven and at best is ambiguous (Dimirgnc-Kuut & Levine 1996; Shleifer and summer 1988). In contributing to this discourse, it was found out that there is a bidirectional causal relationship between stock market development and economic growth.
1.2 Statement of the problem
Capital market which is a division of financial market has a goal primarily to mobilize long term funds for productive purposes and by so doing provide a means for small as well as large scale enterprises to trade in securities by giving them access to public listing. The Nigeria capital market has evolved with growth of Nigerian economy. The performance of all stock listed and the total values of shares outstanding of its listed companies revealed that the market has enjoyed a decade of unprecedented growth over the years.
Prior to 2008, the total market capitalization increased by over 90.0%, however from a peak in march 2008,capitalization went into spiraling decline dropping by about 45.8% by the end of the year (Security and Exchange Commission 2009). Before the financial crises, the Nigeria capital market had remained illiquid and experienced a downward trend in stock prices. And as a result, the market was becoming very risky to invest and less attractive to long term investors, both foreign and local (Business day 2010).
In a study carried by Osaze (2002), capital market rank behind money market in terms of attractiveness to business organization as a source of finance. Adding that, not less than 60% of total savings is in the money market. This may be attributed the loss of confidence by investors as a result of high risk in the capital market. This situation presents danger for the economy because the money market is not designed to provide development funds for big organizations.
Market performance witnessed a serious hike in 2007, gets to its peak around March 2008 and began to witness a sharp decrease in 2009 due to the contagion effect from the global financial crisis. Trading volume and number of listed securities in the Nigeria stock market have been fluctuating over the years. This study therefore examines the effect of capital market volatility on the growth of the Nigeria economy.
1.3 Research Question
Based on the above stated problems, the following research questions were raised for this study;
i. What impact does All share index and number of listed securities have on the economic growth of Nigeria?
ii. Investigate the effect market capitalization and market trading volume have on the growth of the economy of Nigeria?
1.4 Significance of the Study
This study specifically examined the effect of capital market instability on the growth of the Nigeria economy. This study is important because, the Nigeria capital market, which was the toast of many enlightened Nigerians both home and abroad, is now experiencing a meltdown as market capitalization has declined especially, in periods ranging from 2007 to 2015. The All share index has also fallen in the same period. Trading volume and total number of listed securities are also experiencing tremendous movement over the years.
This study is expected to complement the efforts of government and policy makers in reviving the Nigeria stock market and implementing improvements that will add value and stability to the market, making it a world class capital market and in turn, enhance the growth of the Nigeria economy. This study would also consolidate existing literature on the issues surrounding the relationship between capital market and economic growth.
