The Macroeconomic Impact of Crude Oil Price Fluctuations in Nigeria

The main objective of the study was to determine the way fluctuations in the price of crude oil affected macroeconomic variables in Nigeria from 2000 Q1 to 2022 Q4. The data was analysed in the paper using Structural Vector Autoregressive (SVAR) models. According to the findings, Nigeria's current economic growth has been significantly impacted by lag GDP values. This indicates that economic growth in Nigeria was significantly impacted by one-period lag GDP by 3,791.7 units in the short-run and 7,430.4 units in the long-run. Also in the short-run, the current broad money supply was significantly impacted by both the one-period lag general price level (0.445 units) and the one-quarter lag broad money supply (757.7 units). According to the crude oil price fluctuation model, current crude oil price variations in Nigeria are significantly influenced by one-period lags in general price level (-64.9 units), crude oil price fluctuation (1,114.6 units), and fiscal budget deficits (0.65 units). All of the one-period lagged coefficients of macroeconomic variables, including real GDP, broad money supply, interest rates, general price level, inflation rates, and fiscal budget deficits, had a significant impact on current economic growth and broad money supply, respectively, as demonstrated by the long-run economic growth and broad money supply models. The real GDP's impulse response to fluctuations in crude oil prices fell during the first period, peaked during the second, and then increased to show a positive trend during the third. This study came to the conclusion that shocks or fluctuations in the price of crude oil are the main cause of macroeconomic policy instability in Nigeria. The study recommended that the government should control foreign exchange rate regimes, pursue expansionary monetary policy, general price level control and stabilisation measures.
