Introduction
Climate disasters are now costing the United Statesย US$150 billion per year, and the economic harm is rising.
Theย real estate marketย has been disrupted, as home insurance rates skyrocket as wildfire and flood risks rise with the warming climate.ย Food pricesย have gone up with disruptions in agriculture.ย Health care costsย have increased as heat takes a toll. Marginalized and already vulnerable communities that are least financially equipped to recover areย being hit the hardest.
Despite this growing source of economic volatility, the Federal Reserve โ the U.S. central bank that is charged with maintaining economic stability โ isย not considering the instability of climate changeย in its monetary policy.
Earlier this year, Fedย Chair Jerome Powell declaredย unequivocally: โWe are not, and we will not become, a climate policymaker.โ
Powellโs rationale is that to maintain the Fedโs independence from politics and political cycles, it should useย its toolsย narrowly to focus on its coreย mission of economic stability. That includes price stability, meaning keeping inflation low and maximizing employment. In Powellโs view, the Fed should stay away from social and environmental concerns that are not tightly linked to its statutory goals.

However, it is gettingย increasingly difficult for central banksย to ensure stability if they do not integrate climate instability into their monetary policies.
As researchers with expertise inย climate justiceย andย central banks, we recentlyย published a paperย reviewing the monetary policy tools available to central banks around the world that could help slow climate change and reduce climate vulnerabilities.
With the new U.S.ย National Climate Assessmentย andย other researchย making clear that U.S. policies and actions areย insufficient to minimize climate instabilityย and manage the growing economic costs, we believe itโs time toย reconsider the role of central banksย inย responding to the climate crisis.
Rethinking Interest Rates
One thing central banks could do is set lower interest rates for renewable energy development. Theย Bank of Japan has used this strategy.
The Fedโs aggressive increases in interest rates in response to rising inflation haveย slowed the transformationย toward a more sustainable society byย supporting fossil fuelsย and makingย investments in renewable energyย infrastructure more expensive.ย Offshore windย power has been particularly hard hit, with multiple multibillion-dollar projects canceled as higher interest rates raised the projectsโ costs.

One way to introduce differentiated rates would be to create a specialย lending facilityย under which commercial banks could borrow money from the central bank at preferential interest rates if used for renewable energy deployment or other climate-friendly investments. Whether the Fed already has authorization to do that depends on interpretation of its current mandate.
While the U.S. Federal Reserve has not done it before,ย Chinaโs central bankย hasย used similar toolsย to incentivize renewable energy, and the Bank of Japanโs lending facility offersย zero-interest loansย for green investments.
Nudging Banks to Rethink Investments
Despite the Fedโs proclaimed efforts not to pick winners and losers, its monetary policies have taken steps thatย favor established industries and companies, including the fossil fuel industry.
For example, the Fedย supported the financial sector unconditionallyย during the COVID-19 pandemic to keep credit available to limit economic harm. Its massiveย purchases of corporate bondsย resulted inย subsidies to the fossil fuel sector.
Our analysis suggests two ways to help manage climate change now: The Fed can reinterpret its current statutory duties and start viewing climate action as a critical part of its role in maintaining economic stability within its existing mandate,ย as the European Central Bank has done, or the mandate of the Fed can be changed by Congress to explicitly include โgreenโ transformation objectives, similar to theย U.K.โs mandate for the Bank of England.
Either of these options could empower the Fedย to address climate changeย and support the government, businesses, banks, households and communities in financing climate mitigation and adaptation efforts.

The Fed could also discourage banks and investors from investing in assets that ultimately harm the economy โ for instance, byย setting collateral requirementsย for banks that would reduce theย attractiveness of holding carbon-intensive assets. The European Central Bank recently announced that it would tilt purchases ofย corporate bonds toward โgreenโ assets.
The Fed has recently taken steps to pushย large financial institutions to monitor climate-related risksย in their portfolios,ย drawing the ire of Republicans, who claimed the bank had no authority to consider climate change. Whether this risk management approach will pressure banks to change their lending patterns is not yet clear.
The Fed and other central banks could go further andย mandate energy transition planningย with an eye toward economic stability. The European Union developed aย whole new sustainable finance frameworkย designed toย discourage investmentย in economic activities that do not support an energy transition along the lines of theย European Green Deal, which aims to turn Europe into a climate-neutral continent with no one left behind. The European Central Bank is obligated to support EU economic policies, including the green transition.
The Fed Has Used Creative Tools Before
Many times in its 110-year history, the Fed hasย provided financial support to the U.S. governmentย during major crises, such as wars and recessions, by offering direct lines of credit or by directly purchasing Treasury bonds. During the pandemic, it took extraordinary steps to keep U.S. businesses running.
Now that the U.S. is facing rising costs from the climate crisis, we believe the Fed should treat climate change with the same urgency and importance.

In our analysis of the tools available to central banks, we took aย climate justiceย perspective, looking beyond greenhouse gas emission reductions to incorporate social justice and economic equity. Instead of focusing on supporting corporate interests and the financial sector in the short term to stabilize markets, we believe central banks couldย prioritize longer-term stabilityย by funneling investments toward vulnerable communities and people.
Theย Bank of England, theย European Central Bankย and other central banks are already implementing someย pro-climate measures. At the Fed, Powell seems more concerned with political backlash than the economic damage to the U.S. economy outlined in the latest climate assessment.
We believe it is past time that the Fed consider climate destabilization as a major economic crisis and use more of the tools in the central bank toolbox to tackle it.
