financial supervision

Macroprudential supervision: from theory to policy

Financial supervision focuses on the aggregate (macroprudential) in addition to the individual (microprudential). But an agreed framework for measuring and addressing financial imbalances is lacking. We propose a holistic approach for the financial system as a whole, beyond banking. Building on our model of financial amplification, the financial cycle is the key variable for measuring financial imbalances. The cycle can be curbed by leverage restrictions that might vary across countries.
