Examining the Effect of Macroeconomic Instability on Insurance Industry Growth in Nigeria

This study examines the effect of macroeconomic instability on insurance industry growth in Nigeria, using annual time series data from 2000 to 2023. Nigeria's insurance industry has historically struggled to sustain consistent growth trajectories, with premium income growth frequently disrupted by periods of inflation, currency depreciation, oil price shocks, and recession. Understanding the transmission channels through which macroeconomic volatility affects insurance industry growth is important for both strategic planning within the industry and for macroprudential regulatory design. The study employs a time series methodology using annual data on real GDP growth, inflation rate, exchange rate volatility, oil price fluctuations, and monetary policy rate as macroeconomic instability measures, alongside real premium income growth, insurance penetration rate, and insurance density as industry growth indicators. Johansen cointegration tests assess the long-run relationship, while the Vector Error Correction Model (VECM) captures short-run dynamics and adjustment speeds. Impulse response functions trace the growth response to macroeconomic shocks. Preliminary findings are expected to document significant negative effects of inflation and exchange rate depreciation on real premium income growth, with longer adjustment periods following oil price shocks. The research recommends counter-cyclical insurance reserve requirements as a macroprudential stabilization tool.
