The dollar peaked at 114 in September 2022 — its highest level in twenty years — then began a retreat that would define the next era of currency markets. Trump's return to the White House briefly pushed it to 110 on tariff expectations, but the tariffs themselves did the opposite: the Dollar Index crashed from 110 to 96 in six months, its steepest decline since the Plaza Accord. As of March 2026, with the dollar near 98, the question that has haunted international finance for two decades demands an answer.
Every decade produces a new wave of dollar obituaries. After the euro's launch in 1999, commentators predicted a bipolar currency world within a generation. After the 2008 crisis, as the Fed printed trillions, the dollar was supposed to collapse under the weight of its own money supply. After COVID and the weaponization of dollar reserves against Russia in 2022, de-dollarization became not just a theory but a stated policy goal of nations representing over half the world's population.
And yet the dollar has a way of confounding its pallbearers. Its share of global reserves has declined from 72% in 2000 to roughly 58% in 2025 — a real and meaningful shift, but one that has taken a quarter-century and still leaves the dollar with nearly three times the reserve share of its closest competitor. The question isn't whether the dollar is weakening at the margins. It clearly is. The question is whether that erosion represents a slow transition to a multipolar currency system — or whether it's simply the natural adjustment of a currency that was never meant to be quite so dominant in the first place.
Phase 1: The controlled descent (Oct 2022 – Dec 2023). The dollar's retreat from 114 was orderly at first. As inflation cooled from 9.1% to 3.1%, markets began pricing in the end of the Fed's hiking cycle. The DXY fell from 114 to 104 by January 2023, then spent most of the year oscillating between 101 and 107. Two forces kept the decline from accelerating: the Fed held rates at 5.33% even as inflation fell, maintaining a massive interest rate differential, and the regional banking crisis of March 2023 — when Silicon Valley Bank, Signature Bank, and First Republic collapsed in rapid succession — triggered brief safe-haven flows into the dollar. By December 2023, the DXY had settled around 103, down 10% from the peak but far above the pre-pandemic level of 96.
Phase 2: The waiting game (Jan – Oct 2024). This was the most boring period in dollar markets in years — and one of the most consequential. The Fed held rates at 5.33% for thirteen consecutive months, the longest pause since the early 2000s. Markets swung between pricing in six rate cuts and none. The dollar drifted between 101 and 106, unable to break in either direction. In September 2024, the Fed finally cut — by 50 basis points, twice the expected size — and the dollar fell to 101. But the real move was about to come from politics, not monetary policy.
Phase 3: The Trump surge (Nov 2024 – Jan 2025). Donald Trump's election on November 5, 2024, sent the dollar surging. The DXY jumped from 103 to 105 overnight — the largest single-day move since Brexit. Markets priced in the expected consequences of Trump's trade agenda: tariffs would reduce imports, shrink the trade deficit, and force a stronger dollar. By January 13, 2025, the DXY hit 110, its highest level since the September 2022 peak. The dollar was back — or so it seemed.
Phase 4: The tariff crash (Feb – Jul 2025). What happened next was the most dramatic reversal in the dollar's modern history. Trump's "Liberation Day" tariffs on April 2, 2025 — sweeping levies on virtually all US trading partners — didn't strengthen the dollar. They crushed it. The logic that tariffs equal a stronger dollar assumed rational, orderly adjustments. Instead, the tariffs triggered a global reassessment of the dollar's role. Foreign investors, suddenly uncertain about the stability of US economic policy, began reducing their exposure to dollar assets. The DXY fell from 104 in early April to 102 within days, then kept falling — to 100 in May, 99 in June, and 96.4 in July, its lowest level since April 2022. In six months, the dollar had given back everything it gained after Trump's election and then some. The 12% decline from January's 110 to July's 96 was the steepest sustained drop since the Plaza Accord era.

The most striking feature of this table is the break in the dollar-rates correlation. From 1980 through 2022, the dollar reliably strengthened when the Fed raised rates and weakened when it cut. That relationship fractured in 2025. The Fed was still holding rates at 4.33% — among the highest in the developed world — yet the dollar fell 12% in six months. The rate differential that had powered the dollar for four decades simply stopped mattering. Capital flows, it turned out, cared more about policy credibility than interest rate arbitrage.
The partial recovery from 96 in July to 100 in November 2025 suggested the tariff panic was overdone. But the failure to reclaim 100 durably — the DXY slipped back to 97 by early 2026 — indicated something structural had changed. The dollar wasn't collapsing. But it wasn't bouncing back either.
The case for de-dollarization is real, if overstated. The dollar's share of global foreign exchange reserves has fallen steadily: from 72% in 2000 to 65% in 2015 to roughly 58% in 2025. Central banks, particularly in Asia and the Middle East, have been diversifying into gold, the Chinese yuan, the euro, and even the Australian and Canadian dollars. Gold purchases by central banks hit record levels — over 1,000 tonnes in both 2022 and 2023 — with China, India, Turkey, and Poland leading the buying. The freezing of Russia's $300 billion in central bank reserves after the 2022 Ukraine invasion was a watershed: it demonstrated that dollar reserves could be weaponized, and every country with even a hypothetical adversarial relationship with Washington took notice.
BRICS expansion accelerated the narrative. The original BRICS (Brazil, Russia, India, China, South Africa) expanded in 2024 to include Saudi Arabia, the UAE, Iran, Egypt, and Ethiopia — collectively representing over 40% of world GDP and 45% of the global population. The bloc's stated ambitions include a common settlement currency, increased bilateral trade in local currencies, and reduced dependence on the dollar-based SWIFT payment system. China and Russia now conduct the majority of their bilateral trade in yuan. India and the UAE trade in rupees and dirhams. Saudi Arabia, the linchpin of the petrodollar system since 1974, began accepting yuan for oil sales to China in 2023.
But the dollar's structural advantages remain formidable. It still accounts for 88% of all foreign exchange transactions, 47% of SWIFT payments, and roughly 54% of global trade invoicing. US Treasury markets are the deepest and most liquid in the world — there is no alternative asset that can absorb trillions of dollars of global savings with the same safety and convenience. The yuan, despite China's ambitions, accounts for under 3% of global reserves, constrained by capital controls that Beijing shows no sign of lifting. The euro, the dollar's most plausible competitor, has been weakened by the eurozone's chronic growth problems, its fragmented debt markets, and its dependence on American security guarantees.
The tariff episode revealed a more nuanced dynamic. The dollar didn't weaken because the world found a replacement. It weakened because the United States, through erratic trade policy, undermined the very credibility that makes the dollar the world's reserve currency. The dollar's dominance rests not just on American economic size but on a set of institutional commitments: rule of law, predictable policy, open capital markets, and a willingness to run the current account deficits that supply the world with dollars. When those commitments appeared wobbly, the dollar weakened — not because the yuan or euro were suddenly more attractive, but because the dollar became, at the margins, less trustworthy.
Forty years ago, the Plaza Accord brought the dollar down from 165 because it was too strong for the world economy to function. Today, with the DXY near 98, the dollar sits almost exactly where it stood when this series began — at the long-run average that reflects America's actual weight in the global economy. The journey between those two points — through Black Monday, the Asian crisis, the euro's birth, 9/11, the housing collapse, QE, COVID, and the fastest hiking cycle in history — is the story of how the world's most important price found its level.
De-dollarization is real, but it is not a revolution. It is a slow-motion adjustment from a unipolar currency system to a multipolar one. The dollar will remain the world's dominant reserve currency for decades — there is simply no alternative with the depth, liquidity, and institutional backing to replace it. But "dominant" and "monopolistic" are different things. The dollar of 2026 commands less of the world's reserves, less of its trade invoicing, and less of its financial infrastructure than the dollar of 2000. That erosion will continue. The dollar's arc, traced from the Plaza Accord to the present, bends not toward collapse but toward something more ordinary: first among equals, rather than the only game in town.
