Decarbonization’s Dollar Dilemma

The United States is now staring down the barrel of what amounts to a full repeal of the Inflation Reduction Act’s energy tax credits and loan authorities. Not even the House Republicans who vocally defended the law, in the end, voted against President Trump’s “One Big, Beautiful Bill.” To be sure, there’s no final outcome yet — leading Republican senators don’t seem satisfied with the bill headed their way, and energy sector lobbyists are ready to push harder. But the fact that House Republicans were willing to walk away from billions of dollars of public spending for their districts and perhaps $1 trillion worth of economic growth is a flashing red sign that Trump’s politics have capsized the once-watertight argument that the IRA would be too important to American businesses and communities to be destroyed.

The Biden Administration touted the IRA as the United States’ marquee investment not just in reducing emissions and promoting economic development, but also in bringing back American manufacturing to compete against China in the market for advanced technologies. The Trump administration takes this apparent conflict with China seriously ― the threat of economic decoupling looms large ― but seems to have no desire to compete the way the Biden administration did. Rather than commit to the solar, wind, battery, grid, and electric vehicle investments that are laying the foundation for a manufacturing revival, the Trump administration has doubled down on the conjoined ideas that America should be self-sufficient and should play to its strengths: critical minerals, nuclear, natural gas, and even coal. Never mind that Trump’s tariff policy and his party’s deep cuts to energy-related spending will stop these plans, too, in their tracks. “Energy dominance” has always been a smokescreen ― of fossil fuels, by fossil fuels, for fossil fuels.

While Republicans attempt to shut down America’s entire scientific research apparatus, the rest of the world moves on. The demise of the Inflation Reduction Act would decisively surrender the global market for all types of commercialized clean energy sources (and nuclear energy, too) to Chinese companies. Chinese companies already dominate the input sectors for these technologies, whether it’s processing and refining mineral products such as polysilicon, gallium, and graphite, or producing infrastructure commodities such as steel and aluminum. The end of Biden’s climate and infrastructure laws will also leave the American car industry in the dust, as the rest of the world shifts gears toward purchasing more efficient and cheaper electric vehicles ― particularly Chinese brands such as BYD. (Ford’s CEO drives a Xiaomi electric vehicle and “doesn’t want to give it up.”) Consider it a sign of the times that Ethiopia recently banned the import of gas-powered vehicles. Electrification is in, combustion is burnt out.

It’s not just China that benefits. In November, the Net Zero Industrial Policy Lab at Johns Hopkins estimated that the repeal of the IRA leaves up to $80 billion in clean technology manufacturing investment opportunities for other countries to seize between now and 2032, the law’s intended sunset year. Those countries aren’t just the likely (read: wealthier) suspects such as Japan, South Korea, or the European Union. The abdication of U.S. leadership would also boost electric vehicle and battery manufacturing capacity in Morocco, Mexico, India, Indonesia, and elsewhere across Southeast Asia; solar power-related manufacturing further across Southeast Asia; and wind power-related manufacturing in Brazil, Mexico, South Africa, India, and Canada.

These countries won’t just benefit from investors looking to build outside the United States. A Trump-induced fall in American imports of these technologies and their inputs may also drive some degree of global disinflation, insofar as these countries can secure input goods no longer flowing into the American market at cheaper prices. The writing has been on the wall since the early Biden administration that failing to invest meant investing in failure. This is what the Trump administration is poised to do, to the detriment of American technological capabilities and standards of living.

Financial dominance

Just because the United States might be dropping out of the race for global decarbonization, however, does not mean that the rest of the world can choose to ignore the United States in return. The Trump administration can still play spoiler with every other country’s efforts to decarbonize ― even China’s ― for one overarching reason: the mighty dollar. The United States may be hemorrhaging the political capital that coordinating the energy transition requires, but it still controls the currency of decarbonization itself.

It’s hard to overstate how central the management of the U.S. dollar is to the management of global decarbonization. Let’s sketch out some of the key dynamics. First, the dollar is the world’s primary trade currency. Because most global trade is denominated and invoiced in dollars, fluctuations in the value of the dollar relative to the value of other currencies will affect the price of importing both essential commodities and capital goods in other countries. Any volatility in the prices of oil, critical minerals, food, or machinery ― including the inputs to energy systems ― is most likely measured in a currency that every other country needs to earn through trade or borrow from investors. Efforts to denominate commodity trade in other currencies, such as the Chinese renminbi, are not likely to scale up rapidly, however, thanks to the network effect of the dollar system: Market actors will only ditch the dollar if most of their counterparties do.

Second, then, the dollar is the world’s dominating financial currency. Countries seeking foreign investment must issue debt at rates and on terms that foreign investors, many of whom measure their returns in dollars, judge as safe relative to the returns on U.S. Treasury bonds, conventionally the world’s premier “safe asset.” How the U.S. Federal Reserve moves interest rates influences how every other central bank does; higher rates in the U.S. usually push up Treasury bond yields and, as other central banks also raise rates or stockpile dollars, make borrowing for investment and for refinancing debt more expensive across the whole world ― particularly for large-scale energy and adaptation infrastructure projects. The U.S. Federal Reserve also manages the dollar swap lines and repurchase (or “repo”) facilities that provide dollar liquidity to the rest of the world during a financial crisis, as in the Great Recession and the subsequent Eurozone financial crisis, or a sudden dollar cash shortage, as in 2019.

Finally, the United States maintains a comprehensive sanctions regime that operates through cross-border dollar payments systems and “clearing-house” facilities such as SWIFT, which processes interbank payments, and CHIPS, which handles over 90% of all dollar-denominated transactions globally. When the United States wants to cut target companies and whole countries out of the dollar financial system, it prevents SWIFT from processing targeted entities’ cross-border transactions and U.S.-based financial institutions from accepting them.

The Obama administration and first Trump administration used U.S. control over SWIFT and CHIPS to administer sanctions against Iran, and the Biden administration did the same to Russia. The U.S. Departments of Treasury and Commerce also administer what’s known as a “secondary sanctions” regime that imposes these financial penalties on unrelated third-parties that violate initial sanctions. And the Department of Commerce enforces export controls that restrict technology transfer to foreign targets. The Biden administration combined these authorities to limit the ability of both U.S. and foreign companies to export certain technologies to targeted Chinese companies.

Perhaps ironically, some of these dynamics don’t bite the way they used to during the Biden administration, when the dollar was expensive relative to other currencies. Trump’s inflationary and growth-destroying budget, trigger-happy tariffs, and neglect of the fracking sector have driven a sharp depreciation in the dollar and destabilized the market for U.S. Treasury debt. Some cuts to U.S. interest rates are likely given the elevated probability of a recession. All of these factors ― undeniably a bad look for the United States ― should support emerging market financial conditions by lowering the cost of commodity imports, raising the attractiveness of sovereign debt to foreign investors, and help stave off potential debt crises.

But easier global financial conditions in the short term do not diminish the threat the Trump administration continues to pose to global economic stability. The danger that the Trump administration expands the American sanctions regime implemented via the global dollar invoicing system and export controls remains undiminished. What’s more, the tension between the president and Federal Reserve Chair Jerome Powell should alert foreign central banks that their access to the American dollar liquidity facilities is ultimately contingent on the Federal Reserve’s independence from Trump’s influence. During the first Trump administration, the European Union and China alike started strategizing how to derisk their dependence on the dollar; U.S. policymakers should not be surprised if those governments are now dusting off those playbooks.

The motor and the fuels

The dollar’s dominance is in part an effect of the gargantuan size of the U.S. consumer market. Trump’s tariff threats had governments across the world scrambling to cut deals with the United States to preserve their market access ― including by promising to purchase U.S. natural gas.

The view outside the U.S. seems to be that there is no easy replacement for the U.S. consumer. As the Australian Strategic Policy Institute put it, “US household spending in 2023 reached $19 trillion, double the level of the European Union and almost three times that of China. … there are no obvious markets to replace [U.S. consumers].” Indian journalist M. Rajshekhar notes that China, too, needs external markets to absorb its products, and that it cannot count on other Global South countries to let Chinese goods flood their markets. Americans are the motor that keeps the global economy spinning.

The inability to sell goods to the United States is a threat to decarbonization abroad not just because it gives Trump an avenue to hawk natural gas, but also because U.S. consumer spending provides the world with a source of the dollars with which decarbonization is financed in the first place. And to the extent that the IRA would have supported U.S. consumer demand for clean energy technologies and electric vehicles, its de facto repeal ― while a source of potential disinflation for Global South producers ― snuffs out a key demand signal for the production of inputs to those sectors across the Global South.

Where the Global South’s clean energy transition is concerned, natural gas unfortunately remains an important alternative to coal in the absence of widespread renewable energy deployment. The U.S. is the world’s largest exporter of liquified natural gas, the use of which has doubled since 2009 as global demand for the fuel rose sharply. Countries across Europe and Asia depend on U.S. gas for domestic power and industrial uses ― particularly after Russia’s invasion of Ukraine. Large energy importing countries like India increasingly rely on gas to meet energy demand spikes. Over the longer term, industry leaders expect LNG demand to rise 60% by 2040, particularly on the back of persistent Asian demand. Although planned U.S. LNG export capacity is already on track to double between now and 2028, the Trump administration is supporting the buildout of even more capacity to meet this expected global demand.

Becoming dependent on “molecules of U.S. freedom” for industrial growth and for transitioning off of coal may once have seemed like a smart decision across emerging markets, particularly when prices were lower. But it has now left dependent Global South countries uniquely vulnerable to energy import price and power market shocks caused by erratic U.S. policy and volatile (dollar-denominated) natural gas prices. Will the gas-dependent countries in Europe and Asia be able to access enough Chinese imports, invest sufficiently in local clean technology, and kick their LNG fix in time to meet their emissions reduction goals? Europe might; for the rest, this question is one worth following over the coming years.

The truth is that the United States has always had a unique opportunity to weaponize these aspects of dollar dominance in the interest of playing global spoilsport. As Chen Chris Gong, a researcher at the Potsdam Institute for Climate Impact Research, argues in her forthcoming (not yet peer-reviewed) paper on “The geoeconomics of transitioning to the post-fossil world,” Global South countries have an urgent reason to decarbonize built into their politics, whether their governments recognize it or not. So long as much of the Global South is dependent on imported fossil fuels for energy, “local people’s livelihood and firms’ survival are made vulnerable to compound cycles of dollar capital flow and cycles of basic commodity trade.” If the Global South cannot fully avoid the United States, their governments can at least sidestep it. Countries powered by clean energy, importing less fuel, and generating their own power are far more insulated from the dollar cycle and the dollar system, simple as that.

In contrast, as Gong highlights, the only incentives for the United States to pursue decarbonization come from the pressure of competing with China ― a competition that Republicans, for all their bluster, may not actually want to win ― or the pressure of mass consumer demand for a clean economy ― for which Democrats are not exactly fighting tooth and nail ― and the profits both promise. It’s darkly funny that the Inflation Reduction Act’s defenders are seizing on these exact reasons in their attempts to protect the law in the Senate when neither sufficiently moved House Republicans to reconsider.

For posterity, then, we should add another reason, even if it won’t convince Republicans to change tack: The looming repeal of the Inflation Reduction Act portends a future where Trump and his Republican party happily use their control over the global economy to drag the rest of the world down with the United States. “Energy dominance” may always have been formless bluster, but the United States’ financial dominance remains sharp enough to cut ― if not global emissions, then global standards of living.
