A wide range of financial institutions is employed to test the hypothesis that the interest rate risk is priced by capital markets. In addition, the above sample is extended by incorporating firms from the non-financial sector. A two-factor model with the market portfolio and the changes in market yields, as exogenously specified risk variables, is employed. The model is estimated via a seemingly unrelated regression estimation (SURE) framework with both cross-equation restrictions and within equation nonlinear constraints on the parameters. The findings indicate that financial institutions’ equity returns incorporate a risk premium for their exposure to market yields’ surprises. The return generating function of the insurance business could be further explained by an additional factor such as currency movements. It is a...
