A Simple Model of Bank Behaviour—With Implications for Solvency Regulation

Abstract

A simple model of bank behaviour is shown to have implications for solvency regulation of the Basel type. The investment division seeks to maximize RORAC , with higher solvency S lowering the cost of refinancing but tying costly capital. In period 1, exogenous changes in expected returns d μ ¯ and in volatility d σ ¯ occur, causing optimal adjustments dS */ d μ ¯ and dS */ d σ ¯ in period 2. In period 3, the actual adjustment dS * creates an endogenous trade-off with slope d μ ^ / d σ ^ . Basel- type regulation modifies this slope, inducing senior management to opt for a higher value of σ in several situations. Solvency regulation can thus run counter its stated objective.
