History shows that dollar cycles don’t simply fade, they break. And when they do, it’s usually because all four structural forces shift in close succession: trade and geopolitical dynamics, growth and interest rate differentials, cross-border investment flows and some form of FX adjustment, whether coordinated or market-driven.
Since 1970, three full dollar cycles have unfolded. While the trigger points differ, the pattern is strikingly consistent: when the underlying macro, market and policy forces turn, usually within a two–three year window, the dollar trend reverses decisively. The transition is often amplified by feedback loops and repositioning. What follows is typically a self-sustaining cycle in the other direction.

The historical turning points that broke dollar inertia
This section examines in detail each major turning point since Bretton Woods:
1968–1971
The Nixon shock and the collapse of Bretton Woods
By the end of the 1960s, the US current account surplus had vanished, while Vietnam war spending had pushed far more dollars into global circulation than could be backed by gold. Confidence in the US$35 peg began to erode. In 1968, the London Gold Pool – a multilateral effort to stabilise the gold price – collapsed under the weight of persistent European withdrawals, especially by France. The US imposed capital controls soon after, and the eurodollar market expanded rapidly, driven by offshore holdings and a loosening of financial restrictions.
Although this wasn’t yet a period of large-scale private sector investment flows, the eurodollar system made the dollar more vulnerable to confidence shifts. Nixon’s suspension of convertibility to gold in August 1971, backed by a 10% import surcharge, formalised the collapse of the Bretton Woods System. The December 1971 Smithsonian Agreement devalued the dollar and introduced a narrow trading band, but the regime didn’t hold. By 1973, floating exchange rates had arrived.
Classic rate and growth differentials also played a role. As the US entered a stagflationary recession in 1969–71, growth in Germany and Japan held up and they maintained tighter monetary policy. The Fed, under Arthur Burns, focused on recession risks rather than inflation
Past the initial break, the dollar downcycle persisted, fuelled by negative real yields, rising inflation and geopolitical shocks. The Yom Kippur war in 1973 quadrupled oil prices and widened the US twin deficit. Productivity collapsed, and confidence in the dollar weakened further. Central banks quietly diversified reserves, while US investors turned to commodities as an inflation hedge.
1978–1980
Volcker and the return to hard money policy
By the late 1970s, inflation had become politically intolerable. In response, the Carter administration took steps to defend the dollar, including budget restraint, wage and price guidelines, and the issuance of FX-denominated ‘Carter bonds’. This, together with gold sales and massive coordinated intervention by Germany, Japan and Switzerland sent a signal that the US and partners were committed to
defending the dollar.
But the real shift came with Paul Volcker. The US was unprepared for the stagflationary shock triggered by the Iranian revolution in early 1979, which drove oil from US$13 to US$34 per barrel by mid-1980.
That spike helped create the political conditions for a more aggressive policy response. Appointed Fed Chair in August 1979, Volcker abandoned interest-rate targeting in favour of controlling money supply. The federal funds rate surged above 15%, making US real short rates the highest in the world. The economy entered recession in early 1980, but inflation expectations finally began to break. Capital flowed into the US, drawn by both policy credibility and real yield.
Cross-border investment flows also shifted. US equities surged 28% in 1980, marking the beginning of a rotation from bonds to stocks. Foreign direct investment picked up as global capital responded to the policy pivot.
Past the initial break, the new cycle was reinforced by Reagan’s pro-growth agenda: sweeping tax cuts, financial deregulation and a clear political mandate. The Latin American debt crisis helped divert capital into the US, while the spread of personal computing bolstered investor optimism about productivity. All four levers – policy, capital, macro differentials and trade positioning – had shifted.
1984–1986
Plaza Accord and downcycle turning point
But by the mid-1980s, the dollar’s surge had become a problem. Reagan’s fiscal expansion and the strong-dollar policy of the early 1980s had pushed the currency sharply higher, just as the US economy emerged from recession. Twin deficits soared, peaking at 8% of GDP by late 1986. US exporters lost competitiveness and trade protectionism gained traction.

In September 1985, the G5 signed the Plaza Accord to reverse the dollar’s rise and address competitiveness. The Trade and Tariff Act of 1984 had already given the administration new tools to manage trade imbalances, building on earlier voluntary export restraints with Japan introduced in 1981. The policy worked: the dollar fell by 35% over the following year.
A major reallocation of global capital reinforced the adjustment. Japanese and European equities dramatically outperformed - Japan by 160% and Europe, Australasia and the Far East (EAFE) by 100% over the two years following the Accord. Commodities also began a multi-year rally. Meanwhile, US real interest rates fell, and inflation expectations broke down, lowering the dollar’s yield advantage.

After the initial move, the downcycle persisted. US rates normalised post-Volcker, while capital flowed into booming foreign markets. Europe and Japan soaked up global flows, even as many emerging markets struggled with debt restructuring. All four forces - policy, growth differentials, investment flows and currency action – moved together.
1994–1997
The dot.com boom
The mid-1990s dollar upcycle emerged from a distinct blend of structural and cyclical forces. Geopolitically, the dissolution of the Soviet Union removed a major challenge to US leadership. Domestically, fiscal discipline gained traction through spending caps and the 1993 Deficit Reduction Agreement. Meanwhile, a tech-driven productivity boom lifted potential growth estimates - labour productivity averaged 2.8% annually from 1996 to 2000.
Against this backdrop, the Fed raised rates by 300 basis points between February 1994 and February 1995, re-establishing a yield advantage over Germany and Japan. The Deutsche Bundesbank, by contrast, was entering a rate-cutting cycle. When the Mexican peso crisis erupted in April 1994, the Fed led a concerted effort to stabilise markets. The Nasdaq responded with a 132% rally between Q1 1994 and the end of 1995, fuelled by a wave of IPOs and venture capital.
Subsequent EM crises, in Thailand, Indonesia, Korea and Russia, drove investors toward the dollar’s safety and liquidity. Reserve managers increased Treasury allocations. Treasury Secretary Robert Rubin’s ‘strong
dollar’ messaging removed doubts about policy intent.
What followed was a self-sustaining cycle driven by higher productivity, positive carry and rolling bouts of global risk aversion that kept capital flowing into dollar assets through the early 2000s.
2001–2002
EM forever, downcycle turning point
The next turning point came as the US lost its growth and yield advantage. The dot-com bust sent the Nasdaq down 50% between January and April 2001, eroding wealth and cutting capital spending. In response, the Fed cut rates 11 times between January 2001 and June 2003, eventually reaching 1%. At the same time, the Economic Growth and Tax Relief Reconciliation Act of June 2001 (known as the ‘Bush tax
cuts’) and increased post-9/11 security spending marked the end of the Clinton surpluses and the return of widening fiscal deficits, while the current account deficit hovered near 4%.
The War on Terror and the run-up to the Iraq War marked a more assertive US foreign policy, straining relationships with allies. Meanwhile, structural shifts abroad began to take hold. China’s WTO accession in December 2001 triggered a powerful EM export cycle. The euro became a credible reserve currency with the introduction of physical notes and coins in 2002.
Capital began to reallocate. EM equities outperformed the US by 22 percentage points in 2001–02. Commodity-linked currencies gained ground, and the euro rose 25% from mid-2001. Private-sector demand for Treasuries softened even as official reserve buying persisted. The current account deficit began to weigh.

What followed was a near decade-long dollar downcycle. US twin deficits climbed from 10% in 1999 to 25% by 2005. A China-led EM and commodity boom, fuelled by oil prices above US$100, drew capital
away from the US. Asian FX reserve accumulation recycled dollars into Treasuries, but risk appetite for US assets took time to recover. The dollar rallied during the GFC but resumed its decline until 2011.
2011–2014
US exceptionalism, upcycle turning point
The most recent dollar bull phase took shape between 2011 and 2014. It was built on multiple reinforcing shifts: the euro-area sovereign debt crisis, the EM taper tantrum, the US shale revolution and the rise of technology megacaps.
The euro crisis reminded investors of the fragility of non-optimal currency areas and re-established the dollar as the safe-asset of choice. From mid-2011 through mid-2012, yields on Greek, Portuguese and Spanish bonds surged, triggering a systemic flight to US Treasuries. That safety bid soon converged with policy divergence. After completing QE2, the Fed began discussing tapering in December 2013 and ended asset purchases in October 2014. Rate hikes followed in 2015. In contrast, the ECB launched outright QE in January 2015, and the BoJ expanded its programme in late 2014, widening the short-rate spread in favour
of the dollar.
The divergence channelled flows into the US just as large-cap tech earnings began to re-rate. Microsoft and Google’s trailing P/E ratios rose sharply. At the same time, the collapse in oil prices from 2014–15
undermined the terms of trade for many emerging markets, further boosting the relative appeal of the dollar. The taper tantrum of 2013 highlighted how exposed EM assets were to a stronger dollar and
tighter US monetary policy.
Each of the four forces – trade and geopolitical stress, yield differentials, investment flows and policy asymmetry – aligned in favour of the dollar. The result was a powerful upswing that carried through 2016 and again during the 2022–24 rate-hiking cycle.
