After the global financial crisis that started in 2007, central banks in advanced economies eased monetary policy by reducing interest rates until short-term rates came close to zero, limiting options for additional cuts. Some central banks used unconventional monetary policies, buying long-term bonds to further lower long-term rates. Some even took short-term rates below zero. In response to the COVID-19 pandemic, central banks took actions to ease monetary policy, provide liquidity to markets, and maintain the flow of credit. To mitigate stress in currency and bond markets, many emerging market central banks used foreign exchange interventions, and for the first time, asset purchase programs. More recently, in response to rapidly growing inflation, central banks around the world have tightened monetary policy by increasing interest rates.
The global financial crisis of 2007-2009 showed that countries needed to identify and contain risks to the financial system as a whole. Many central banks adopted the use of prudential tools and established macroprudential policy frameworks to promote financial stability. Macroprudential tools are used to build buffers and contain vulnerabilities that make the financial system susceptible to shocks. This reduces the probability that shocks to the financial system disrupt the provision of financial services and cause serious negative consequences for the economy. Central banks are well placed to conduct macroprudential policy because they are able to analyze systemic risk and often are relatively independent and autonomous. Independence and autonomy are important because the institution responsible for macroprudential policy should be able to withstand political pressures and opposition from industry groups.
