Key Takeaways
- The US Dollar experienced its most significant first-half decline since 1973 during the first six months of 2023, driven by expectations of a Federal Reserve policy pivot and resilient global growth.
- However, this weakness proved temporary. The dollar subsequently staged a robust recovery from the second half of 2023 into 2024, propelled by persistent US economic outperformance and a “higher for longer” interest rate narrative.
- Despite its recent strength, the dollar faces long-term structural headwinds, including a burgeoning US national debt and concerted de-dollarisation efforts from geopolitical blocs like the expanded BRICS partnership.
- For investors, this volatility underscores the need for dynamic currency hedging strategies and a nuanced view of US corporate earnings, where a strong dollar pressures exporters but benefits importers.
The US Dollar’s performance through the first half of 2023 was nothing short of remarkable, marking its weakest six-month start to a year since 1973. This pronounced decline against its global peers was not a fleeting statistical curiosity but a reflection of a significant, albeit temporary, shift in macroeconomic sentiment. While the narrative has since reversed course, the episode serves as a critical case study in the forces that govern the world’s primary reserve currency and the structural risks that continue to simmer beneath the surface.
Anatomy of the 2023 Decline
The dollar’s precipitous fall in the first half of 2023 was the culmination of several converging factors. After a period of immense strength in 2022, driven by the Federal Reserve’s aggressive rate-hiking cycle, the market began to price in a policy pivot. Inflationary pressures appeared to be peaking and then receding, leading investors to anticipate an end to monetary tightening and the eventual start of rate cuts. Simultaneously, economic prospects in Europe and China showed signs of improvement, diminishing the dollar’s appeal as the sole safe-haven asset.
This environment created a powerful tailwind for other major currencies. The US Dollar Index (DXY), a weighted average of the dollar’s value relative to a basket of six major currencies, slid significantly during this period. The move was less about a fundamental collapse of the dollar and more about the unwinding of an extreme valuation premium built up over the preceding year.
The Narrative Reverses Course
The predictions of sustained dollar weakness, however, proved premature. Beginning in the latter half of 2023 and extending into 2024, the currency staged a formidable rebound. The primary catalyst was the surprising resilience of the US economy, which consistently outperformed expectations and its developed market peers. This economic dynamism, coupled with stubbornly persistent inflation, forced the Federal Reserve to adopt a “higher for longer” stance on interest rates, pushing back the timeline for anticipated cuts.
This policy divergence once again made holding dollar-denominated assets more attractive, reigniting demand for the currency. The weakness seen in early 2023 was effectively erased as the market recalibrated its expectations for global monetary policy.
Performance in Perspective
The dollar’s journey over the past two years has been a tale of two distinct halves. The sharp decline in H1 2023 was followed by an almost equally sharp recovery. The table below illustrates the approximate performance of the US Dollar Index (DXY) across these key periods to contextualise the volatility.
| Period | Approximate DXY Change (%) | Primary Driver |
|---|---|---|
| H1 2023 (Jan-Jun) | -2.7% | Expectations of Fed pivot; global growth optimism. |
| H2 2023 (Jul-Dec) | +2.5% | US economic outperformance; “higher for longer” rates. |
| YTD 2024 (Jan-Present) | +3.5% | Delayed Fed rate cuts; relative US economic strength. |

Structural Fault Lines and Future Risks
Despite the dollar’s robust recovery, it would be a mistake to ignore the underlying structural risks that the 2023 decline briefly illuminated. The most prominent of these is the trajectory of US sovereign debt, which continues to expand at a pace that raises long-term sustainability questions. A perpetually rising debt burden could eventually erode investor confidence and weigh on the currency’s value.
Furthermore, geopolitical dynamics are slowly chipping away at the dollar’s hegemony. Nations within the BRICS bloc and beyond are actively seeking to conduct more trade in local currencies, reducing their reliance on the greenback for international settlements. While the dollar’s dominance in global finance and trade is not under immediate threat, this gradual shift represents a significant long-term headwind. It is a slow-moving process of diversification rather than an abrupt replacement.
For portfolio managers, the recent cycle offers a clear lesson: currency markets are increasingly driven by shifting policy expectations and relative economic performance. A strong dollar remains a headwind for US-based multinational corporations that generate substantial revenue overseas, as it makes their products more expensive and erodes the value of repatriated profits. Conversely, it benefits US importers and can help temper domestic inflation.
As a concluding hypothesis, consider that the brief but sharp dollar downturn of 2023 may have served as a dress rehearsal. Should the US economy falter while its structural issues—namely its fiscal imbalance—become more acute, the next dollar down-cycle could be more prolonged and severe, potentially catalysing a more meaningful reallocation of global capital towards alternative currencies and assets.
