DTWEXBGS at 121.3202: Reading the Dollar Gauge
The Nominal Broad U.S. Dollar Index stood at 121.3202 on 2026-10-23. Here is what that number measures, its units, and how to apply it across assets.
The Nominal Broad U.S. Dollar Index (DTWEXBGS) was recorded at 121.3202 on 2026-10-23, according to the Federal Reserve data republished through FRED. That single value is a point-in-time reading of a daily, not seasonally adjusted index whose base is January 2006 = 100.
The dash "2026-10-23" is the observation date, and the release is ascribed as of 2026-10-26T20:16:00+00:00 in the source metadata. For investors holding crypto, gold and U.S. equities side by side, the headline value matters less than understanding what the gauge tracks and what it cannot tell you.
What the index actually measures
The series comes from the Board of Governors of the Federal Reserve System, published under the H.10 Foreign Exchange Rates release. Its unit is a January 2006 = 100 index, and it is not seasonally adjusted. That combination means the number is a relative measure, not a price or a rate of return.
Reading 121.3202 means the weighted currency value is about 21.32% above its January 2006 baseline. That percentage is a Calculation I derived from the index level and its stated base, and it should be treated as approximate since the published figure is rounded to four decimals.
Because the base is fixed at January 2006 = 100, comparisons across long periods stay anchored. A reading above 100 signals strength relative to that base; a reading below 100 signals weakness. What the index does not provide is a single exchange rate against one currency — it blends a broad set of trading partners.
Confirming the units and freshness
Three details in the series metadata deserve attention before anyone uses the number. First, the unit statement is "Index Jan 2006=100" — anyone comparing it to a raw currency quote is comparing unlike things. Second, the frequency is daily, so the series updates on trading days rather than in real time. Third, the series is marked not seasonally adjusted, which means seasonal patterns in trade and settlement are left in the data rather than removed.

The source also advises reviewing copyright information in the series notes before sharing, and it directs data questions to the data source and FRED-functionality questions to the FRED team. The metadata itself adds an option to select automatic updates or a static time frame, which is a setting description rather than a new data point.
How to use it in a cross-asset comparison
The practical use of DTWEXBGS is alignment, not prediction. If you compare a crypto position, a gold position and a U.S. equity position over the same calendar window, the dollar index lets you ask whether the window's currency backdrop moved. A higher index reading is one piece of context for dollar-sensitive assets; it is not evidence of direction for any single one.
A disciplined approach has three steps. First, fix the window to match the observation date you cite, since the series is daily and not adjusted for seasonality. Second, label the index as a relative gauge with a January 2006 base rather than a price. Third, treat any statement about correlation between the index and another asset as an inference, and only after checking that both series share the same dates and adjustment treatment.
Worked example of the base conversion
To translate the index into a rough change from its baseline, subtract 100 and divide by 100. For the 2026-10-23 value: (121.3202 − 100) / 100 = 0.213202, or roughly 21.3%. Both figures are a Calculation; the underlying index level is the only hard observation.
This conversion is useful only as a descriptive shorthand. Because the series is nominally weighted against a basket, a 21.3% figure above base does not mean a single currency pair moved 21.3%. It means the blended nominal gauge stands that far above its January 2006 reference level.
Risk mechanism: why nominal broad matters
The "nominal" label is a risk-relevant distinction: it means the index measures the currency value without adjusting for inflation. Over long spans, that leaves the door open for confusing a nominal currency move with a real purchasing-power move. The "broad" label means the basket spans many trading partners rather than a narrow set, which broadens the read but dilutes any single bilateral move.
For portfolio risk, the mechanism is indirect. A dollar gauge that captures many partners can move with global capital flows, trade balances and policy expectations, and those same forces can move crypto, gold and equities differently. The index tells you the backdrop; it does not assign causes.
What the source does not say
- The source does not state which currencies are in the basket or their weights.
- It does not state the previous observation, an average, or a change figure; only the 2026-10-23 level is given.
- It does not state which dates were trading days or why 2026-10-23 was the observation shown.
- It does not provide inflation-adjusted or real values, and no real index level is given.
- It does not assert any relationship between the index and crypto, gold or equities.
- It does not state a period-average or revision history.
The honest reading is narrow: a defined gauge, one dated observation, and explicit unit and adjustment labels. Anything beyond that is the reader's own analysis built on stated assumptions, and should be labeled as such.
