Abstract

Very few contributions have analyzed the effect of inflation on the US insurance industry. We evaluate the impact of inflation on reinsurance demand, liquidity creation, ROA and other financial ratios for P&C insurers, with panel data and with particular attention to differences across firm sizes. We use observed and forecasted measures of inflation during the period 1993-2023. We compute forecasted rates of inflation from the Bayesian Vector Autoregression (BVAR) model under two different assumptions, the Gaussian distribution and the Student-t distribution. We proceed with the Generalized Method of Moments (GMM) for econometric estimations. Overall, the findings indicate that insurers are responsive to forecasted inflation in the long run as well to realized inflation in the short run. Largest insurance companies adapted more quickly to inflation during the period of analysis.
