We study the effects of a temporary Green QE, defined as a policy that temporarily tilts the central bank's balance sheet toward green bonds, i.e. bonds issued by firms in non-polluting sectors. To this purpose, we merge a standard DSGE framework with an environmental model. In our model,...

We use a DSGE model to study the effectiveness of green-asset purchases by the central bank (Green QE), along the transition to a carbon-free economy driven by an emission tax, abstracting from price stability considerations. We find that Green QE helps to further reduce emissions, especially in...

This paper investigates the impact of central banks when supporting policies aiming at greening the financial system. The July 2021 Monetary Policy Strategy Review of the European Central Bank unexpectedly dedicated a whole workstream to climate change. The announcement had a significant effect...

This paper focuses on the trade–offs that central banks would face if they were to start tackling climate change. Disruptive natural events can hamper growth and capital accumulation, thereby affecting price and financial stability – elements for which central banks are responsible. Yet, the...

As it is becoming clear that climate change will exert a major impact on inflation, economic growth, and financial system stability, central banks and financial regulators have increasingly recognized that they can no longer ignore climate change and other environmental issues. In general,...

This paper examines the channels via which climate change and policies to mitigate it could affect a central bank's ability to meet its monetary and financial stability objectives. We argue that two types of risks are particularly relevant for central banks. First, a weather-related natural...

This paper discusses how financial stability governance has evolved and how central banks and financial regulators are coping with the threats posed by climate uncertainty, providing an overview of G20 countries' green central banking experiences in the past 20 years. The analysis shows that...

The awareness about climate-related financial risks is gaining momentum both in the policy and academic debates. The role of countries' institutional dimension and central bank governance structures in the adoption of green prudential regulation is, however, overlooked in the current discussion....

Central banks and financial supervisors approach "green finance" mostly to preserve macroeconomic and financial stability according to their mandates. Obviously, climate change poses severe risks to households, firms and their financial intermediaries. These risks tend to be correlated and their...
