This study examined the relationship between monetary policy and the performance of the Nigerian capital market using annual time series data sourced from the Central Bank of Nigeria Statistical Bulletin. The objective was to examine the long and short run relationship that exists between monetary policy variables and the performance of Nigerian capital market. Market capitalization and market turnover was modeled as the function of interest rate, exchange rate, monetary aggregates, monetary policy rate and treasury bill rate. The study applied the Ordinary Least Square (OLS) regression technique and causality, unit root, cointegration, vector error correction estimates. Findings revealed that interest rate, exchange rate monetary aggregate and monetary policy rate have positive and significant relationship with market capitalization but treasury bill rate have negative and significant relationship with market capitalization. Monetary policy rate, monetary aggregate and exchange rate have positive relationship with market turnover while Treasury bill rate and interest rate have negative and significant relationship with market turnover. The unit root test found the variables stationary at first difference, the cointergration test validates the presence of long run relationship, the granger causality test proved unidirectional causality while the vector error correction estimates justified adequate speed of adjustment. The study concludes that monetary policy has significant relationship with performance of Nigeria capital market. We recommend that the monetary authorities should ensure effect monetary policy transmission mechanism that will enhance the performance of the capital market.
