Quick Answer
The US Dollar Index (DXY) has had a genuinely volatile 2026: after a strong start to the year, it collapsed to a four-year low near 96.19 in late January amid a specific political shock, then continued grinding down to a fresh 2026 low of 98.55 on August 22 — its weakest level since mid-May — before staging a recovery back above 99 in early September on stronger-than-expected jobs data and rising Fed rate-hike odds. The “de-dollarization” narrative gets significant attention in financial media, and there’s real substance behind parts of it, but independent analysis suggests the popular explanation for 2026’s dollar weakness — that it’s simply about Fed rate cuts — doesn’t actually fit the data particularly well.
The Dollar’s Rough Start to 2026
To understand where the dollar stands now, it helps to see the full arc of its decline. The DXY closed 2025 relatively strong, but had already been on a downward trajectory since early in that year: after sitting at 109.39 on January 2, 2025, the index fell below 100 by April 2025, when President Trump announced reciprocal tariffs on countries selling into the US market. The dollar’s slide accelerated sharply in late January 2026, following a specific and highly unusual political event.

The Powell Investigation: A Specific Catalyst
MarketPulse’s real-time analysis from late January 2026 describes what happened plainly: the Dollar Index was already showing technical signs of weakness when President Trump launched a criminal investigation into then-Fed Chair Jerome Powell and simultaneously threatened historic US allies — and what had been, in MarketPulse’s words, “a slow, progressive dedollarization quickly became a catastrophe for the US Dollar.” Some European funds reportedly began selling dollar-denominated debt assets specifically in response to these developments, actively seeking alternatives and further reducing dollar demand. The DXY bottomed at 96.19 on January 29, 2026 — its weakest level in at least the prior year, according to Indonesian financial data provider Databoks’s tracking of the index.
This episode is worth connecting to a related story we covered separately: the same period saw gold surge past $5,000 an ounce for the first time in history, a move we detail in our piece on gold’s historic 2026 rally. That’s not a coincidence — a weakening dollar and surging gold prices are two sides of the same underlying story about eroding confidence in US institutional stability during that specific window.
Why the “It’s Just Fed Cuts” Explanation Doesn’t Fully Hold Up
This is where independent research pushes back meaningfully on the conventional media narrative. VaaSBlock’s mid-2026 analysis makes a specific, data-driven argument: the standard explanation for dollar weakness — that it’s caused by narrowing interest-rate differentials as the Fed cuts rates — doesn’t actually fit what happened, because the Fed barely cut rates at all during this period, and the yield premium on US Treasuries over German Bunds or Japanese government bonds remained significant throughout. In other words, if interest-rate differentials were the primary driver, the dollar shouldn’t have weakened nearly this much.
VaaSBlock’s analysis instead identifies three overlapping forces: fiscal credibility concerns (tied to the deficit dynamics we’ve covered in our piece on the FY2026 budget deficit), institutional de-dollarization at the margin (central banks and some large institutional investors gradually diversifying reserves), and a structural rotation out of dollar-denominated assets by a subset of investors reacting to the specific political events of early 2026. Importantly, the analysis also cautions against overstating the trend in the other direction: it notes that the “de-dollarization narrative is real but routinely overstated in both directions,” pointing out that the dollar’s share of global central bank reserves has declined from around 71% in 1999 to roughly 57% by 2026 — a meaningful, genuine long-term shift, but a gradual one playing out over decades, not a sudden 2026 phenomenon.
Is De-Dollarization Actually Accelerating?
There’s real evidence of institutional shifts happening alongside the dollar’s price moves, independent of the specific January 2026 shock. TradingKey’s analysis, drawing on January 2026 data, cites several concrete developments: BRICS nations announced plans to increase the share of trade settled in local currencies from 35% to 50%; ASEAN announced plans to establish a regional unified payment system by 2027 specifically to reduce dollar reliance; and the share of local-currency settlement in Brazil-China bilateral trade reached 40%, up 10 percentage points in a single year. Global central banks also net-sold $48 billion in dollar reserves that January alone, pushing the dollar’s overall share of global foreign exchange reserves to 58.2%, a new low since 1995 at that point.
It’s worth being precise about how to weigh this evidence: these are real, documented shifts, but they represent gradual reallocation at the margin, not a wholesale abandonment of the dollar’s reserve-currency status, which remains dominant by a wide margin even after these changes.
The September Rebound
The dollar’s trajectory shifted again heading into September 2026. Trading Economics data shows the DXY held around 99 in early September, “supported by stronger-than-expected US jobs data that reinforced expectations of a Federal Reserve interest rate hike in September.” Specifically, data released the prior Friday showed US nonfarm payrolls rose by 162,000 in August — comfortably exceeding forecasts for a gain of 56,000, and a sharp reversal from July’s revised increase of just 23,000. Currency forecasting firm Cambridge Currencies captured the shift precisely in its September outlook: through the first half of 2026, markets had assumed the Fed’s next move would be a rate cut; by September, markets were pricing the opposite — a hike — as more likely than not, which is itself unusual, since it makes the near-term path for the dollar genuinely two-sided for the first time all year, rather than following a clear downward trend.

What the Forecasts Actually Say
Cambridge Currencies’ analysis frames a dollar forecast, at its core, as really a forecast of where US interest rates will go relative to other major economies. The firm’s September 2026 outlook lifted its near-term DXY floor to 98 for September and October, while maintaining a wider six-month range of 95 to 102 — a genuinely broad band that reflects real uncertainty rather than a confident directional call. Part of that uncertainty ties directly to the euro, which carries the heaviest single weighting in the DXY basket: EUR/USD reached a three-month high of 1.1710 on August 20 before easing, with the European Central Bank’s own June projections showing eurozone headline inflation at 3.0% for 2026 alongside weak growth of just 0.8%, complicating the euro’s own trajectory and, by extension, the dollar index’s mechanical calculation.
What Dollar Volatility Means for You
- Imports and travel abroad: A weaker dollar makes imported goods and international travel more expensive; a stronger dollar makes them cheaper — the 2026 swings mean this effect has moved in both directions within a single year.
- US exporters and multinational earnings: A weaker dollar can boost the competitiveness of US exports and lift the reported dollar-value of overseas earnings for US multinational companies.
- If you hold international investments: Currency swings this large can meaningfully affect the dollar-denominated returns on unhedged foreign holdings, independent of how those underlying assets actually performed.
- Don’t over-extrapolate from a single data point: Both the January collapse and the September rebound show how quickly the dollar’s near-term trajectory can shift on a single political or economic surprise.
Frequently Asked Questions
Why did the US dollar fall in early 2026?
The dollar fell sharply in January 2026 following a Trump administration criminal investigation into then-Fed Chair Jerome Powell and threats against historic US allies, which accelerated an already-developing pattern of dollar weakness and prompted some European funds to sell dollar-denominated assets.
Is the US dollar losing its reserve currency status?
Not imminently. The dollar’s share of global reserves has declined gradually from about 71% in 1999 to roughly 57% by 2026, a genuine long-term trend, but the dollar remains the dominant global reserve currency by a wide margin.
Why did the dollar recover in September 2026?
A stronger-than-expected August jobs report (162,000 new jobs versus 56,000 expected) shifted market expectations toward a Federal Reserve rate hike rather than a cut, supporting the dollar’s rebound.
What is the DXY dollar index forecast for the rest of 2026?
Cambridge Currencies’ September 2026 forecast projects a range of 98 to 102 for the near term and 95 to 102 over six months, reflecting genuine market uncertainty about the Fed’s next move.
