How much has the dollar dropped in the last six months

1. The headline: a double‑digit slide over 12 months, but six‑month figures vary by benchmark

Market trackers and financial sites report that the U.S. Dollar Index (DXY) and similar measures have lost roughly a tenth of their value over the past year — TradingEconomics reports the dollar is down about 10.6% over 12 months, TradingView shows a similar ~10.4% annual decrease, and Investing.com reports roughly a 9–11% decline depending on the dataset used ^[1][2][3]; those 12‑month yardsticks are useful for context but do not directly answer a six‑month change because index movements are sensitive to the chosen start and end dates and to which currencies are weighted in the basket ^[5].

2. Currency‑pair snapshot: dollar versus euro over the most recent six months

For a concrete six‑month view in one major pair, Wise’s historical data shows that on Jan. 28, 2026 the USD/EUR rate hit 0.8342 and that the highest recent USD/EUR quoted on Aug. 1, 2025 was 0.8755, which implies a drop of roughly 4.7% from that summer peak to late‑January; Wise also reports the six‑month average USD/EUR was 0.8573 and that the current rate is about 2.7% below that six‑month average, so against the euro the dollar’s recent slide is clearly measurable but smaller than the year‑long decline ^[4].

3. Why six‑month answers diverge: index composition, timing and measurement matter

Different sources measure "the dollar" in different ways — the DXY is a weighted basket of six currencies (euro, yen, pound, Canadian dollar, krona, franc) and so will move differently than a pair like USD/EUR; macro providers (TradingEconomics, TradingView, Investing.com) and official Fed series (broad trade‑weighted indexes on FRED) use distinct baskets and weights, so a six‑month percent for one series is not interchangeable with another ^[1][2][6].

4. The political narrative and volatility: big six‑month draws have precedent but need fact checks

Reporting and punditry have pointed to an abrupt six‑month tumble in past windows — for example Morningstar and fact‑checks noted a near‑11% fall in the first half of 2025, a statistic highlighted by PolitiFact — but that finding referred to that specific six‑month stretch and a particular weighted average, illustrating how dramatic short windows can look even as other measures or later recoveries moderate the picture ^[7].

5. Bottom line for the last six months: no single number in the sources, but ranges are clear

The assembled sources do not provide a single, consensus "last six months" percent for a universal dollar measure, but they give a bounded answer: against the euro, recent highs this summer to the Jan. 28, 2026 low imply roughly a 4–5% decline and the current USD/EUR sits about 2.7% below the six‑month average reported by Wise ^[4]; for broader gauges, the dollar is down roughly 9–11% over the past year according to multiple data providers, underscoring that the six‑month change is smaller than the 12‑month slide but materially negative depending on the benchmark chosen ^[1][2][3].
