Climate finance was a major focus at the recent COP28 summit, but one set of game-changing institutions remains largely missing in such conversations: central banks.

Central banks are , charged with maintaining through controlling the supply of money in an economy. These banks have enormous power to catalyze a more just, equitable and climate-stable future.

However, our points out that their policies have been slowing down—rather than speeding up—transformative climate action. The problem is these banks focus on in the near term, which means propping up a status quo which promotes further climate instability. And that means they are making things more unstable in the long term.

suggests that long-term cannot be achieved without first disrupting and transforming the existing financial system. One way to do this would be for to use tools to them to trigger a short-term intentional disruption in order to redirect financial flows and create greater stability in the long-term—we call this .

Short-term vs. long-term stability

Central banks generally try to keep the economy stable by controlling through . With climate disruptions causing more and more instability every year, are starting to take the climate more seriously. Yet, when price stability is threatened by increasing inflation or when the overall financial stability is questioned by a looming financial crisis, central banks quickly forget about the climate.

For example, recent aggressive increases in interest rates have and made it harder for people and governments to raise money for other measures that would help cut emissions or adapt to climate change. From a long-term perspective and from a climate justice lens, this is counterproductive.

To maintain short-term economic stability when COVID hit, central banks around the world quickly lent money to commercial banks in a variety of ways—even at . But no strings were attached, so banks lent this money to the and other wealthy corporate interests, among others.

During the pandemic many central banks also increased the money supply, in a process called , to stimulate the economy, and some of this money ended up in the . These efforts to stabilize reinforced and exacerbated huge inequities in wealth and power, and were a missed opportunity to increase support for a green economy.

Central banking, climate-justice style

That's why in our we analyzed central banks from the lens of . is an approach to climate action that goes beyond a narrow focus on decarbonization and emissions and focuses on social change and economic equity as a way to make people less vulnerable to climate change. This means restructuring the financial system to work for the benefit of all people rather than just the top 1%.

So instead of stabilizing markets by supporting corporate interests and the financial sector in the short-term, we suggest that central banks need to start prioritizing long-term stability. An intentional short-term "creative disruption" would reverse established financial flows and would start funneling investments towards the most vulnerable.

For example, central banks could use their power to create money to help local governments finance ambitious climate infrastructure projects or directly support community-oriented public investment programs.

Rather than continuing to focus narrowly on inflation to determine economy-wide interest rates, central banks could create for different kinds of investments—establishing high interest rates for carbon-intensive activities and low or zero-interest rates for renewable energy. The is one of a few central banks that have already started experimenting with such schemes.

Central banks can also create zero or negative-interest rates for climate justice investments. Imagine households could insulate homes, install heat pumps and solar panels—and get paid for it. And the most vulnerable communities should be served first, not last. If central banks can use negative interest rates to save banks during the COVID crisis, they surely can use such tools to save people and the planet in the climate crisis. Innovations like this could transform the financial landscape, and reshape the financial injustices that dominate today. And there is central banks can do.

Central banks have the power and the tools to trigger a rapid transformation towards a more just, fossil-fuel free future at a global scale. Instead of continuing to use their power to accelerate climate chaos, central banks could catalyze a shift toward a more equitable financial system. Going forward, the transformative role of central banks needs to be at the top of the policy agenda.
