Macroprudential policy emerged as a distinct framework after the 2007–2008 global financial crisis, when policymakers concluded that supervising banks one by one (microprudential supervision) had failed to capture system-wide vulnerabilities such as correlated exposures, asset-price bubbles, and procyclical credit growth. The term itself predates the crisis—it appears in Bank for International Settlements documents from the late 1970s—but it became operational only after 2009.
The core idea is that financial stability is a public good and that risks can build up across the system even when each individual bank looks safe. Macroprudential tools therefore aim to dampen the financial cycle and strengthen system resilience. Common instruments include:
- Countercyclical capital buffers (CCyB), introduced under the Basel III framework finalised by the Basel Committee on Banking Supervision in 2010–2011.
- Loan-to-value (LTV) and debt-to-income (DTI) caps on mortgages, widely used in jurisdictions such as Hong Kong, South Korea, and New Zealand.
- Capital surcharges on global systemically important banks (G-SIBs), designated annually by the Financial Stability Board.
- Liquidity requirements such as the Liquidity Coverage Ratio and Net Stable Funding Ratio.
- Sectoral risk weights targeting real estate or foreign-currency lending.
Institutional architecture varies. The United States created the Financial Stability Oversight Council under the Dodd-Frank Act of 2010. The European Union established the European Systemic Risk Board the same year. The United Kingdom houses macroprudential authority in the Bank of England's Financial Policy Committee, created in 2013.
Debates continue over effectiveness, calibration, and political economy. Tightening LTV caps is unpopular with borrowers and developers, and tools can be circumvented through non-bank intermediaries—so-called shadow banking. The IMF and BIS publish regular assessments of how macroprudential measures interact with monetary policy, capital flows, and exchange-rate regimes.
Example
In 2022, the Bank of England's Financial Policy Committee raised the UK countercyclical capital buffer rate to 2%, citing elevated risks from household and corporate debt.
Frequently asked questions
Monetary policy uses interest rates and money supply to manage inflation and aggregate demand. Macroprudential policy uses regulatory tools—capital buffers, lending limits, liquidity rules—to contain systemic financial risk. The two interact but typically sit with different bodies.
