The causal relationship between financial development and economic growth is a controversial issue. For Cameroon, empirical studies have provided mixed result. This study seeks to empirically explore the relationship and the causal link between financial development and economic growth in Cameroon between 1970 and 2006. The empirical investigation is carried out using time methods and the five most commonly used indicators of financial development in the literature. However, the causal relationship was carried out using two different methods which are the autoregressive distributed lag bounds testing (ARDL) and the vector error correction model (VECM). Using this above methodology the study first found that in Cameroon, there is a positive and long-term relationship between all the indicators of financial development and economic growth which was proxied by the real per capita GDP. With respect to the causality test, the two methods used provide mixed results. In Cameroon the study found that financial development causes economic growth using the two methods.
