Key Takeaways

• The US dollar index current reading on the Vantage feed was 101.601 as of 09:53 (GMT+8) on 21 October 2026, below both its 50-hour and 200-hour moving averages.
• The Intercontinental Exchange (ICE) US Dollar Index touched 102.94 after the 14 October Consumer Price Index (CPI) report, then slipped to around 101.50 on 20 October, a three-week low. ^1,6
• As of 20 October, markets priced about an 83% chance of a Federal Reserve hold on 28 October and a 94% chance of a December hike. ⁶

The US dollar index today sits at 101.601 on the Vantage USDX feed as of 09:53 (GMT+8) on 21 October 2026, below where it stood before last week’s hot September CPI report. That print sent the DXY index to an 18-month high. ² A week on, the rally has gone, yet markets still price a December hike. ⁶

So what happened? Two things, in order. First, bets on an October move by the Federal Reserve (Fed) faded, taking the air out of the CPI spike. Then, on 19 and 20 October, the euro and yen appeared to take over the steering. For anyone following US dollar index news, that second leg is the one most headlines missed.

Instrument Snapshot: As of 09:53 (GMT+8) on 21 October 2026, the Vantage USDX price was 101.601, 0.02% higher on the hourly bar; the ICE US Dollar Index’s 52-week range is 95.55 to 102.94. ¹⁰

The Short Answer: Why the US Dollar Index Slipped

The US dollar index gave back its CPI rally as October hike bets faded, falling to a two-week low on 16 October. It then slipped to a three-week low on 20 October as the euro steadied and the yen firmed after record Japanese bond demand.

Hot Inflation Lifted the DXY Index, Then Let Go

The spike had a clear trigger. US consumer prices rose 3.7% from a year earlier in September, up from 3.4% in August and above the 3.6% economists expected. ⁴ Gasoline alone accounted for more than half of the monthly rise, and core CPI climbed 2.6% against a 2.5% forecast. ³ Principal Asset Management’s Seema Shah said the data reinforced the view that “inflation remains too persistent for the Fed to declare victory”. ⁴

The DXY index jumped to 102.94, its highest since April 2025. ^1,2 Mesirow Currency Management’s Uto Shinohara told Reuters that October rate expectations jumped after the release, “bringing the meeting more into play”. ² By that afternoon, though, the index was easing again, with a 65% chance of no October move priced. ¹

If you had the USDX chart live that night, the Vantage price ran from near 102.00 to near 102.70 on 14 October, and the 14-period Relative Strength Index (RSI) jumped above 80, then sank to near 30 by 15 October. Overbought to nearly oversold in a day: roughly the shelf life of that CPI excitement.

Hot inflation explains the spike. It doesn’t explain why the dollar index then fell below where it started.

Federal Reserve Hike Bets Moved to December

The tempting explanation is that hike bets collapsed. They didn’t. The Fed lifted its policy range to 3.75% to 4.00% on 16 September in a 12-0 vote, ⁵ and on 20 October markets priced a 94% chance of another hike in December, against an 83% chance of a hold this month. ⁶ The hike moved on the calendar, not off it.

It’s a global cycle, too: the Fed, the European Central Bank (ECB), and the Bank of Japan (BoJ) all raised rates within eight days in September. Then, on Friday 16 October, Fed Chair Kevin Warsh declined to signal this month’s outcome, saying hotter inflation had not changed his view of the economy, and the index fell to around 101.6, a two-week low. ⁶ That is where most of the CPI rally went: the premium for an early move lost its footing.

US data didn’t help either. On 20 October the index hit around 101.50, a three-week low, as housing starts fell 5.2% in September, pending home sales dropped to a record low, and oil eased on hopes for a diplomatic path in the Middle East conflict. ⁶ Those factors explain part of that second leg. The rest sat abroad, because most of the dollar index does.

The Euro and Yen Did the Heavy Lifting

Here’s the detail that changes how the USDX index reads. The euro carries 57.6% of the six-currency basket, ahead of the yen at 13.6%, the pound at 11.9%, the Canadian dollar at 9.1%, the Swedish krona at 4.2%, and the Swiss franc at 3.6%, ⁶ a mix fixed since 1999. ⁹ By weight, it’s mostly a euro index wearing a US flag.

That weighting showed up on cue. Violent weekend protests in France weighed on the euro on Monday 19 October, and the French-German 10-year yield spread widened 9.9 basis points to 147.3 basis points. ⁷ The dollar index rose 0.2% to 101.98 that day, and the US 10-year Treasury yield was flat at 5.131% in early Asian trade the next morning. ⁷ Even so, Pepperstone’s Chris Weston said “the euro’s resilience suggests traders aren’t yet treating it as a systemic European problem”. ^7,14

Then the unrest eased. On Tuesday the euro steadied, the yen jumped after a Japanese bond auction drew record demand, and the dollar index slipped to 101.85 as USDJPY eased to 158.14. ⁸ On the Vantage chart, the 19 October push to near 101.87 and the 20 October dip to near 101.30 match those headlines far better than any shift in Fed pricing.

For those two sessions, the dollar index followed Paris and Tokyo more closely than Fed pricing, which is exactly what a combined 71.2% euro and yen weighting allows.

The December hike is still priced. What faded was October, and 71.2% of the index is euro and yen.

That’s the driver picture. Now for what it did to the chart.

USDX Chart: Below Both Hourly Averages

As of 09:53 (GMT+8) on 21 October 2026, the dollar index USDX reading of 101.601 sat just under the 50-hour moving average near 101.64 and below the 200-hour average near 101.90 on the TradingView setup used for this analysis. The faster line crossed beneath the slower one around 15 October and has drifted lower since.

Price climbed off the 20 October low near 101.30, the lowest point in the window, within hours. RSI read 50.86 at the cut-off, back at the midline and above its own moving average of 44.68. Momentum has firmed; price hasn’t cleared the 50-hour average 0.036 overhead, roughly one candle wick.

Those are the lines on the chart. Next week’s calendar is where the euro and Fed stories meet again.

Three Central Banks in Two Days

In GMT+8 terms, the Fed, ECB, and BoJ all decide on 29 and 30 October. Here’s the forex news today calendar on our radar:

• Fed Decision, 29 October 2026, 02:00 (GMT+8): The statement lands at that hour; ¹¹ with a hold largely priced, ⁶ the December language may say more than the decision.
• US Q3 Gross Domestic Product (GDP) and September Personal Consumption Expenditures (PCE), 29 October 2026, 20:30 (GMT+8): PCE is the Fed’s preferred inflation gauge. ⁶
• ECB Decision, 29 October 2026, 21:15 (GMT+8): Day two of the 28 to 29 October meeting, ¹² and the euro is 57.6% of the index.
• BoJ Decision, 30 October 2026: Policy decision and Outlook Report after a two-day meeting; ¹³ the yen is 13.6% of the index.
• French Political Headlines, Ongoing: The 19 and 20 October sessions showed how quickly Paris reached the index. ^7,8

Our read is that October hike timing drove the CPI give-back and the euro and yen drove the latest leg. It weakens if December hike pricing shifts sharply after the Fed statement, putting US rates back in charge, or if USDX holds above both hourly averages while the euro stays calm, which would point to dollar-specific demand.

US Dollar Index Ticker, Basket, and Futures FAQ

What is the ticker symbol for the US dollar index?

DXY is the US dollar index ticker most data providers use for the spot index, while USDX futures trade on ICE Futures U.S. under the symbol DX. ⁹ Vantage quotes it as USDX. Three labels, one basket.

Which currencies make up the US dollar index?

Six: the euro, Japanese yen, British pound, Canadian dollar, Swedish krona, and Swiss franc, with the euro at 57.6% of the weighting. ^6,9

Is USDX the same as DXY?

Same basket, so you’ll see it as US dollar index USDX or DXY, but quotes differ by venue: on 21 October, the Vantage USDX price sat about 0.19 below the ICE spot level of roughly 101.79. ⁶

Gap Risk Around a 02:00 Federal Reserve Decision

Back to the puzzle: how did hot CPI and a hiking Fed fail to hold the dollar index up? The hike didn’t disappear; it moved to December, which took the CPI spike with it, and the euro and yen then set the pace for the latest leg lower.

The index’s sleepy reputation didn’t survive the week: from near 102.70 on 14 October to near 101.30 on 20 October, the Vantage USDX price covered roughly 1.36%. The Fed decision lands at 02:00 (GMT+8), when much of Asia is offline.

A Stop Loss can limit a loss to a planned size, though a fast move around a central bank decision can fill it at a worse price than the level set, and positions held through 29 and 30 October face that gap risk three times. Our forex risk management guide explains how gaps affect stop orders.

Leverage on index and forex CFDs magnifies gains and losses alike. At an illustrative 1:100 setting, a 1% move in USDX equals 100% of the margin posted, which is why position size in proportion to account equity matters most in weeks packed with scheduled decisions.
