For as long as the dollar has reigned supreme, pundits have been predicting its demise. The arguments are familiar: America spends more than it earns, debt piles up with no end in sight, and rival powers are eager to escape its financial grip. Every decade seems to deliver a new round of “de-dollarization” headlines. Yet time and again, the U.S. currency has confounded the skeptics—rallying just when it looked most vulnerable.
Today, as Washington runs record deficits and geopolitical blocs from BRICS to the Gulf explore alternatives, the narrative has returned with fresh urgency: the dollar’s supremacy is slipping. And yet, the paradox is that these very strains may fuel one more surge. The global financial system is so entangled with the dollar that weakness at the core can provoke a scramble at the periphery, forcing borrowers, banks, and even governments to clamor for greenbacks.
The stage is set for what might be the dollar’s “last dance”—a powerful rally that precedes, but does not prevent, an eventual erosion of its dominance.
A Currency That Defies Logic
By traditional measures, the dollar should be under pressure. The United States is running deficits above 6% of GDP, debt-to-GDP has breached 120%, and interest costs are absorbing a record share of federal revenues. The 2023 downgrade of U.S. sovereign credit highlighted concerns long discussed in academic circles: how long can the world’s largest debtor keep borrowing at will?
Meanwhile, geopolitical rivals have grown louder in their calls for alternatives. China promotes the renminbi in Belt and Road projects, Russia has shifted energy exports to ruble or yuan settlements, and Brazil has experimented with local-currency trade finance. The Gulf states flirt with pricing oil outside the dollar. Central banks have trimmed their holdings of Treasuries in favor of gold.
On paper, the dollar’s position looks fragile. In reality, it remains overwhelming. More than 80% of global trade finance is conducted in dollars. Nearly 60% of central bank reserves are dollar-denominated, far outweighing America’s 24% share of global GDP. Roughly half of all cross-border loans and international bonds are issued in USD. Even cryptocurrency markets, heralded as post-sovereign money, are largely priced and settled against stablecoins backed by the dollar.
This disconnect between perception and practice explains why the dollar often rallies when logic says it should fall. Weak fundamentals in Washington are more than offset by the structural demand embedded in balance sheets worldwide.
The Architecture of Dependence
The reason lies in the global plumbing of finance. For decades, companies, banks, and sovereigns outside the United States have borrowed in dollars. By the end of 2024, non-U.S. borrowers owed $13.2 trillion in dollar loans and international bonds. These are not cosmetic choices. A Korean shipping firm or an Indian manufacturer may find dollar funding cheaper and more liquid than borrowing in won or rupees.
But the convenience carries risk. Earnings are denominated in local currencies, while debts must be serviced in dollars. A surge in the greenback inflates liabilities overnight, straining cash flows and balance sheets. Economists describe this as an “implicit short” on the dollar—a bet that the currency will remain stable or weak. When it strengthens, the debt burden rises.
Layered on top is a vast “shadow” dollar system. Through derivatives markets, firms and investors swap local currency into dollars without showing the exposure on their balance sheets. According to the Bank for International Settlements, by late 2023 dealer banks were juggling $91 trillion in outstanding FX swaps and forwards involving the dollar. Of this, roughly $28 trillion amounted to hidden dollar obligations by non-U.S. corporates—twice the size of their disclosed borrowings.
Banks themselves are deeply entangled. Non-U.S. banks carry $21 trillion in dollar liabilities on balance sheets, plus another $20–25 trillion in off-balance-sheet exposures. The vast majority of this activity is booked outside the U.S.—in London, Hong Kong, Singapore, or Zurich—where institutions cannot directly tap the Federal Reserve. In calm markets, this system hums smoothly. In stress, it becomes a global dollar squeeze.
History Lessons: Crises in the Key of USD
The dollar’s tendency to strengthen in crises is not theoretical—it is historical pattern.
When Asia’s tiger economies imploded in 1997, it was not simply a story of speculative attacks. Many corporates had borrowed heavily in dollars. As local currencies collapsed, their debts ballooned, forcing waves of defaults and IMF bailouts.
During the global financial crisis of 2008, the epicenter may have been U.S. housing, but the tremors spread through the dollar funding system. European banks, with trillions in off-balance-sheet dollar liabilities, suddenly found themselves unable to roll funding. The Federal Reserve responded with extraordinary swap lines to foreign central banks, effectively acting as global lender of last resort.
In 2011, as the eurozone’s sovereign crisis deepened, the dollar rallied sharply despite America’s own debt ceiling theatrics. European banks scrambling to secure dollars were among the drivers.
And in March 2020, at the height of the pandemic panic, the dollar spiked violently. Investors sold everything—bonds, equities, emerging-market currencies—to obtain dollars, the currency of settlement for global margin calls and corporate obligations. Again, the Fed’s swap lines became the relief valve.
Each episode reinforces the same truth: no matter the narrative, when stress rises, dollar demand trumps fundamentals.
The Plaza Accord and Its Legacy
To understand the rhythm of dollar cycles, it is worth revisiting the Plaza Accord of 1985. At the time, the dollar had appreciated nearly 50% against major currencies in just five years, creating severe trade imbalances. The world’s leading economies coordinated intervention to weaken the dollar. For a time, it worked. But the episode underscored how the dollar’s role is not dictated solely by Washington’s fiscal discipline or Wall Street’s preferences. It is embedded in the global order.
The Accord was meant to reset imbalances, yet it also deepened global reliance on coordinated dollar management. Three decades later, such coordination is harder to achieve in a multipolar geopolitical landscape. The lesson, however, endures: when the dollar moves, the world must respond.
Emerging Markets: On the Frontline of a Dollar Squeeze
The countries most at risk are those with large external debts and fragile reserves. Argentina has defaulted repeatedly under the weight of dollar liabilities. Turkey has struggled as corporations faced a mismatch between lira revenues and dollar obligations. Even China, often presented as a challenger, carries significant corporate exposure to dollar debt, particularly in property and financial sectors.
When the dollar strengthens, capital flees emerging markets, currencies weaken, and central banks burn reserves to defend exchange rates. The cycle feeds on itself. A “last dance” rally in the dollar could therefore trigger another wave of debt crises across the developing world, even as the U.S. grapples with its own fiscal challenges.
The consequences are not confined to sovereigns. Commodity producers that price exports in dollars, from copper in Chile to oil in Nigeria, see revenue volatility amplify when exchange rates swing. Inflationary pressures mount as imports become more expensive in local terms, forcing central banks into painful rate hikes.
Investors and Executives: Navigating the Dollar Trap
For multinationals, dollar volatility is not an abstract risk. A sudden strengthening can erode earnings translated from overseas operations, inflate debt burdens, and disrupt supply chains priced in USD. Treasury departments must think in scenarios, not averages. Hedging strategies, liquidity buffers, and diversified funding sources are critical.
For portfolio managers, the temptation to short the dollar based on U.S. deficits is strong—but often perilous. Betting against the greenback has humbled some of the world’s most sophisticated macro hedge funds. The smarter strategy may be to anticipate squeezes and position for asymmetric moves, particularly against emerging-market currencies.
For policymakers, the paradox is sobering. Calls for de-dollarization may be politically appealing, but dismantling the system is far harder than rhetoric suggests. As long as trade invoicing, debt issuance, and financial derivatives remain overwhelmingly dollar-centric, the world will still rush to the Fed’s safety net in crises.
The Federal Reserve: Reluctant Global Banker
The Fed’s role as global lender of last resort is an underappreciated pillar of the dollar system. Swap lines with other central banks, first improvised during the 2008 crisis, have become a standing feature of international finance. When markets seize up, the Fed extends dollars abroad to prevent a funding collapse.
This role is politically controversial. Critics argue that the Fed is bailing out foreign banks at U.S. taxpayers’ expense. Supporters counter that stabilizing global dollar liquidity ultimately protects the U.S. economy by preventing contagion. Either way, the reality is unavoidable: without the Fed’s interventions, the shadow dollar system could unravel during crises.
The irony is striking. The more the world depends on the dollar, the more indispensable the Fed becomes to non-Americans. Yet the more the Fed intervenes, the more entrenched the system grows. It is a feedback loop that keeps the dollar’s primacy alive, even against mounting evidence of U.S. fiscal fragility.
Toward a Multipolar Future?
Does this mean the dollar will rule forever? Hardly. Long-term structural shifts are already under way. The renminbi’s role in regional trade is rising, albeit slowly. The euro remains significant within Europe. Gold is quietly making a comeback in central bank reserves. And digital currencies—whether central bank digital currencies (CBDCs) or blockchain-based stablecoins—could gradually chip away at the dollar’s transactional monopoly.
Moreover, America’s fiscal path is unsustainable. Interest costs may exceed defense spending within a decade. If confidence in Treasuries wanes, so too will the foundation of dollar liquidity. The endgame may not be collapse, but erosion—an incremental decline toward a more multipolar system.
Yet before that future arrives, one last surge seems likely. A global shock—whether financial, geopolitical, or economic—could send the dollar soaring once again, straining emerging markets and confounding predictions of decline.
In jazz, the last dance is often the most frenetic, filled with improvisation before the lights come up. The dollar may be approaching such a moment. Weakness in fundamentals, paradoxically, is what makes a surge likely: the global system is built so tightly around the greenback that stress anywhere translates into demand everywhere.
