When economists search to account for the greenback’s outsize function as the one true international foreign money, they level to structural elements such because the US share of world GDP, or the depth and liquidity of US monetary markets. This method underlies the sanguine view of many monetary market contributors that, come what could, as long as the US stays the world’s main economic system, the greenback will stay its secure haven.
The second Trump administration is a reminder that uncooked numbers can solely take us to date. For as historians will let you know, it’s the actions of individuals, not economies or markets within the summary, that designate how worldwide currencies rise and fall. It was individuals who took the essential steps to construct the establishments that made the worldwide greenback. And it’s individuals who will in the end decide whether or not these similar establishments survive or fail.
The person with the strongest declare to patrimony of the worldwide greenback might be Paul Warburg, German-American scion of the Hamburg-based Warburg banking household. The younger Warburg labored in worldwide finance in Hamburg, Paris and London earlier than marrying into the Kuhn, Loeb banking dynasty in 1895 and emigrating to the US in 1902. In depth worldwide expertise impressed upon Warburg the benefits accruing to Britain from London’s place because the main supply of commerce credit score and funding finance for retailers and bankers in various components of the world. These various components included the US, which was virtually fully depending on London and sterling for worldwide credit score.
Like many a naturalised citizen, Warburg was deeply loyal to his new nation. He nervous that the American economic system’s dependence on London and sterling uncovered it to overseas shocks over which it had no management. He appreciated additionally that London’s attraction as a global monetary centre rested on the backstopping efforts of the Financial institution of England, which stood able to act as lender of final resort, guaranteeing the market’s liquidity and stability. It adopted that any aspirations the US might need needed to promote worldwide use of the greenback had been hamstrung by the absence of a central financial institution.
Concerning the paintings

Beginning in 1906, Warburg grew to become a tireless promoter of the creation of this establishment. One of many potential central financial institution’s key features, he argued, can be to develop a market in dollar-denominated credit score devices to be used in financing worldwide commerce. Adopting European parlance, he referred to those financial institution drafts or payments of alternate as commerce acceptances, anticipating that the central financial institution would “settle for” or purchase them as a method of lubricating the brand new market in commerce credit score.
Warburg wrote newspaper columns. He spoke at public boards, overcoming shyness born of closely accented English. In 1910 he was a part of the small group of specialists who met on Jekyll Island, off the Georgia coast, to thrash out the provisions of what grew to become the Federal Reserve Act. In 1914 he grew to become a founding member of the Federal Reserve Board. The laws he drafted allowed the Fed to buy greenback commerce acceptances as a method of fostering the market. By the Nineteen Twenties, that market had grown to the purpose the place the worth of greenback commerce acceptances matched, and in some years exceeded, the worth of commerce credit originated in London and denominated in sterling.
The greenback’s standing as a rival to sterling suffered a setback within the Nineteen Thirties, when the Fed withdrew from the acceptance market and the US suffered a collection of debilitating banking and monetary crises. America emerged from the second world struggle because the western world’s solely superpower, creating a gap for the greenback. Nevertheless it took the intervention of one other singular particular person, Harry Dexter White, to cement the buck’s worldwide function.
White got here from extra modest origins than Warburg. His dad and mom had been Lithuanian immigrants, his father a peddler who went on to open a ironmongery store. A prickly character, White pursued an unrewarding tutorial profession earlier than becoming a member of Henry Morgenthau’s Treasury Division in 1934 and rising to assistant to the secretary with full accountability for Treasury’s participation in all worldwide financial and monetary issues associated to the second world struggle. Throughout the struggle, White drafted the plan that grew to become, with modifications, the US blueprint for the IMF, the World Financial institution and the Bretton Woods System, the establishments that supplied the premise for the postwar worldwide financial order and the dominance of the greenback.
To make sure, the US needed to negotiate with different nations current on the worldwide financial convention convened at Bretton Woods, New Hampshire, in 1944. White needed to parry along with his British interlocutor, John Maynard Keynes. However key components of the White Plan went straight into the Bretton Woods settlement.
Particularly, White sought to differentiate the greenback as the one absolutely convertible worldwide foreign money of the newly minted Bretton Woods System. An early draft of the settlement learn that alternate charges must be pegged to gold or “gold-convertible currencies”. When one in every of Keynes’s colleagues, Dennis Robertson, innocently noticed that solely the greenback was apt to be freely convertible into gold following the struggle, White noticed a chance to cement the greenback’s function. He and his workforce stayed up all night time, redrafting the settlement to exchange “gold-convertible currencies” with “gold . . . or the US greenback of the load and fineness in impact on July 1, 1944”. The Bretton Woods settlement thus singled out the greenback because the solar round which the opposite components of the postwar worldwide financial system revolved.
The following interval of greenback dominance was not attributable solely to White and the establishments created at Bretton Woods. It took the Marshall Plan to offer Europe with the {dollars} wanted to renew worldwide funds and reintegrate its economies into the worldwide order. US leaders needed to bypass Congress’s reluctance to hitch the Worldwide Commerce Group by agreeing to determine the Normal Settlement on Tariffs and Commerce.
The US supported European integration and creation of the European Financial Group, a place that reassured European policymakers of the knowledge of counting on the foreign money of a steadfast alliance companion. Nato confirmed the Europeans that that they had not simply an financial companion but additionally a geopolitical companion on whose commitments — and foreign money — they might safely rely. Strong US development advised them that America might stand behind its obligations.
Thus, even when the Bretton Woods System of alternate charges pegged to the greenback broke down in 1971, the buck’s international centrality lived on, supported by the establishments constructed by Warburg, White and their compatriots: an unbiased Federal Reserve, an open world buying and selling system to which the US and its companions had been dedicated, and a rock-solid geopolitical alliance. The greenback’s continued dominance derived from sheer numbers — from the US’s massive share of worldwide GDP and monetary transactions — however equally from relationships and reciprocity.
It has taken Donald Trump just a few months to weaken if not destroy these relationships and that reciprocity. Trump and his appointees query the very values and preparations on which practically a century of greenback dominance is predicated. For the primary time in dwelling reminiscence, the survival of the establishments on which that dominance rests has been solid into doubt.
To start out, America’s financial exceptionalism is doubtful. The US economic system has outperformed these of different superior nations lately. It’s house to the world’s main tech firms. It’s on the forefront of analysis in synthetic intelligence. It has a start-up-friendly tradition the place serial entrepreneurs are forgiven their failures, and a well-developed enterprise capital trade to seed new enterprises. It’s a magnet for overseas expertise.
However there isn’t any assure that what was true prior to now might be true sooner or later. The analysis capability of the general public sector and US universities is being gutted. Whether or not expert migrants will nonetheless see America’s pearly gates as welcoming is an open query. Coverage uncertainty and doubts about rule of regulation threaten to make America a much less enticing place to speculate.
The US share of worldwide exports has fallen considerably for the reason that early Fifties, from 18 per cent to simply 11 per cent. There’s nothing unhealthy about this pattern in and of itself. It displays profitable post-second world struggle reconstruction of the worldwide economic system, a course of by which America had a substantial hand. However an extra decline within the US share of worldwide commerce, engineered by skyscraper tariffs imposed by politicians satisfied that worldwide commerce is a zero-sum recreation, can be decidedly unhealthy. Historical past is replete with examples of how a rustic’s business hyperlinks help worldwide use of its foreign money — and the way disruption of these hyperlinks undermines a foreign money’s worldwide standing.
It’s simple to see why. The foreign money of the main buying and selling nation is a pure habitat for its exporters and importers, who loom massive in international markets. There’s then an incentive for exporters and importers elsewhere, when searching for to do enterprise with this main economic system, to equally utilise its foreign money, given its comfort for his or her prospects and suppliers. The inducement is comparable for overseas entities searching for to borrow on this dominant nation’s monetary markets. Consequently, when the load of an economic system in international commerce and finance declines, the market forces making for widespread use of its foreign money have a corresponding tendency to weaken. A perverse “America First” tariff coverage harmful of US commerce would speed up this course of.
As well as, there’s a hazard to the greenback from haphazard US use of sanctions. Even earlier than Russia’s assault on Ukraine and sanctions on Russian entities, America had more and more turned to this monetary weapon: the variety of people topic to US sanctions had risen from 912 in 2000 to greater than 9,400 in 2021. Sanctions imposed on Russia in 2022 sharpened the motivation for nations to hedge their bets by diversifying away from the greenback, given the likelihood that Russia’s greenback property may not solely be frozen but additionally garnished and repurposed for Ukrainian reconstruction, setting a precedent for what different nations might undergo.
Importantly, nevertheless, these sanctions had been imposed in co-operation with America’s allies, leaving the Russian authorities few alternate options to the greenback to be used in worldwide funds. However right here too, previous will not be prologue. European nations weren’t on board with the primary Trump administration’s coverage of “most stress” on Iran and its reimposition of sanctions towards the nation.
The decline of transatlantic co-operation in Trump’s second time period factors to the excessive probability of extra such disagreements. Trump has not precisely been cautious in threatening to unleash financial weapons, be they tariffs, sanctions or different measures. When making use of them, he has not co-operated with different nations — fairly the opposite. If the US continues to go its personal method, then the currencies of different nations, these that don’t take part in US sanctioning efforts, would be the beneficiaries of diversification away from the greenback.
Then there’s America’s troubled fiscal and monetary outlook. The greenback has been enticing to central banks as a type of overseas reserves, and to company treasurers, sovereign wealth fund managers and worldwide buyers usually, as a result of it’s accessible in ample quantities whereas nonetheless holding its worth. The US has supplied a gradual provide of {dollars} to fulfill the liquidity wants of an increasing world economic system with out supplying so many as to erode confidence of their worth.
But when this has been true till now, US fiscal and monetary woes might, within the not-too-distant future, push the greenback over the sting. The Congressional Funds Workplace’s long-term funds outlook exhibits debt within the fingers of the general public rising from 99 per cent of GDP in 2024 to 116 per cent in 2034, 139 per cent in 2044 and 166 per cent in 2054. Impending laws, together with measures that stretch Trump’s expiring 2017 tax cuts, might push debt up even sooner. There isn’t a magic debt-to-GDP threshold the place confidence is routinely misplaced. However infinite tax cuts, legendary expenditure reductions and excessive ranges of political polarisation will in some unspecified time in the future trigger overseas buyers to doubt the greenback’s prospects.
If {dollars} are a pretty retailer of worth and technique of fee as a result of they’re anticipated to carry their worth, then steps by the Trump administration to undermine the independence of the Federal Reserve would critically injury the buck’s sights. In February, Trump signed an govt order asserting that “officers who wield huge govt energy should be supervised and managed by the folks’s elected president”. He instructed all “so-called ‘unbiased regulatory companies’” to submit their regulatory proposals for overview by the White Home previous to enactment. His appearing solicitor-general, Sarah Harris, asserted to the Senate that the Division of Justice would now not defend provisions requiring the president to quote “trigger” when dismissing an unbiased company head.
It’s unclear whether or not such orders will in the end be invoked to problem the independence of the Fed or the safety of Jay Powell’s appointment as chair. However Trump has simply fired the 2 Democrat members of the unbiased Federal Commerce Fee. International buyers will draw their very own conclusions.
There are questions, furthermore, about whether or not overseas holders of US debt securities will proceed to be handled pretty. Scott Bessent, Trump’s Treasury secretary, has reportedly mulled the potential for changing five- and 10-year US treasury bonds held by overseas buyers into 100-year securities bearing low rates of interest, whether or not these buyers prefer it or not. Throughout the 2024 presidential marketing campaign, advisers to Trump akin to Robert Lighthizer mooted the potential for taxing overseas purchases of US treasuries as a method of driving down the greenback and enhancing the competitiveness of US exports.
Trump’s nominee to move his Council of Financial Advisers, Stephen Miran, in his earlier incarnation as funding strategist, endorsed such a coverage and described the way it may be applied. Miran proposed slapping a “consumer price” on overseas official holders of treasury securities by withholding a portion of their curiosity funds. Labelling the measure a consumer price as a substitute of a withholding tax would keep away from violating worldwide tax treaties. However it could fall foul of the expectation that home and overseas buyers are to be handled comparably, an expectation that could be a basis stone of the greenback’s worldwide standing. This effort to restrict overseas purchases of US treasuries as a method of depreciating the greenback, one thing that Trump and his advisers evidently see as fascinating, might shortly get out of hand.
Lastly, the greenback’s international function will undergo if the US is perceived as turning its again on its allies. Nations maintain as reserves and use in worldwide funds the currencies of their alliance companions. Not solely are these companions seen as dependable stewards of their overseas balances, however holding the foreign money of 1’s ally is taken by the companion as an indication of excellent religion. Earlier than the primary world struggle, members of the Triple Alliance (Germany, Austria-Hungary and Italy) and the Triple Entente (France, Britain and Russia) held as overseas reserves the currencies of their alliance companions. Nonetheless different nations held as reserves the currencies of nations with which that they had safety understandings.
Within the Nineteen Thirties, not solely the Commonwealth and Empire but additionally a good variety of Britain’s different allies held their reserves in London and pegged their alternate charges to the pound within the association often known as the Sterling Space. Within the Sixties, the German and Japanese governments supported the greenback, serving to to protect its worldwide foreign money standing, due to the worth they connected to their defence alliance with the US, and particularly to US navy forces stationed on their shores. Immediately, Taiwan, South Korea and Japan maintain a disproportionate share of their overseas reserves in {dollars} as a result of they rely on the US safety umbrella. Within the wake of Trump’s Oval Workplace blow-up with Volodymyr Zelenskyy and appeasement of Russia, this notion that alliance politics are vital for worldwide foreign money standing is about to obtain a real-time take a look at.
In the end, the destiny of the greenback will activate the willingness of America’s leaders to uphold the rule of regulation, respect the separation of powers and honour the nation’s commitments to its overseas companions. It is going to rely on the readiness of Congress, the courts and the general public to carry their toes to the hearth. Who would have thought it could come to this?
