Staff Working Paper No. 969

By Andrea Ferrero, Richard Harrison and Benjamin Nelson

The global financial crisis prompted the rapid development of macro-prudential frameworks and an increased reliance on borrower-based policy tools, which influence the demand for credit. This paper studies the optimal design of one such tool, a loan-to-value (LTV) limit, and its implications for monetary policy in a model with nominal rigidities and financial frictions. The welfare-based loss function features a role for macro-prudential policy to enhance risk-sharing. Optimal LTV limits are strongly countercyclical. In a house price boom-bust episode, the active use of LTV limits alleviates debt-deleveraging dynamics and prevents the economy from falling into a liquidity trap.
