This paper evaluates the dynamic causal relationship between financial development, savings, investment and economic growth in Botswana from 1976-2014 by employing a multivariate causality model. Results reveal that it is chiefly investment that drives the bank-related and stock exchange-based financial sectors in the short run. Stock exchange-based financial development drives bank-related financial development and savings in both the short run and the long run. While, savings are found to Granger-cause investment. Economic growth Granger-causes investment and savings, both, in the short run and long run. Further, only bank-related financial development is found to Granger-cause economic growth in Botswana.
