Foreign Exchange Market Demand Pressure and Economic Growth in Nigeria

Abstract

The study has investigated the relationship between foreign exchange market demand pressure and economic growth in Nigeria from 1986 to 2018. The study has used the Marshall-Lerner theory of the demand and supply of foreign exchange. The employed the Autoregressive Distributed Lagged (ARDL) model and Granger Causality test to investigate this relationship. Findings of the study revealed that there exist negative relationships between the foreign exchange market demand pressure and economic growth in both short and long run on the one hand and negative relationship between inflation and economic growth on the other hand both in the short and long run. It was concluded that foreign exchange market demand pressure affects economic growth in Nigeria directly and indirectly via the exchange rate pass-through to domestic prices mechanism. The study recommended that first, the Nigerian economy should be diversified away from oil using the agriculture and manufacturing sectors as articulated in the Economic Growth and Recovery Plan of the Buhari’s administration. By diversification, multiple streams of supply of foreign exchange in the economy will be created to close the existing gap between its demand and supply in the country. Also, by diversification of the economy, the demand for imported goods will reduce. The reduction in the demand for imported goods into the country presupposes reduction in demand for foreign exchange. With this, the scarce foreign exchange can be conserved for only importation of capital goods for onward production of goods and services in the country. Thirdly, the Central Bank should regulate the supply of foreign exchange to only critical sectors of the economy. The activities of the importers should also be checked to avoid cases of over invoicing and under invoicing. These activities generally lead to round-tripping with its adverse consequences on the demand and supply of foreign exchange in the country.
