The debate about the influence of financial market development on economic growth has been ongoing for more than a century. Since Schumpeter (1912) wrote about the happenings on Lombard Street, right up to the economists of today, there is growing interest into how financial market development affects economic activity and hence economic growth. With economic growth gaining prominence in respect of development discourse, inquiry into the finance-growth nexus has grown rapidly. The latest advances of the finance-growth nexus show a positive relationship between financial market development and economic growth. In this regard, little research has been done globally pertaining to most recent economic developments, especially concerning the BRICS economies. This research investigates the influence of financial market development on emerging economies, BRICS and non-BRICS and to determine whether the openness of financial markets in BRICS economies contributed to higher growth trajectories compared to their non-BRICS counterparts. The research utilises the Generalised Method of Moments and an extended endogenous growth model to estimate the influence of a set of financial market indicators. The study found that higher levels of credit to the private sector and financial depth in the BRICS economies contributed to the higher levels of economic growth experienced in the BRICS compared to non-BRICs emerging economies.
