The main innovation is to consider how falling asset prices affect the banking system through wide-spread borrower default, while deriving explicit solutions and balance sheet effects even far from the steady state. We find that the effect of falling asset prices is indirect, non-linear, and involves feedback from the banking system in the form of a credit contraction. When borrowers repay, the effect ‘passes through’ the bank balance sheet; once borrowers default, asset prices drive bank capital, and constrained credit in turn drives asset prices. This interaction can explain capital crunches, financial instability, and banking crises, either as fundamental or as self-fulfilling outcomes.
