September 28, 2026 | USD / Dollar Index Research cut-off: 10:23 UTC / 15:53 IST. This article uses reported European-morning prices and completed historical sessions. Intraday observations are not closing levels.
The US Dollar Index remained close to two-month highs on Monday, September 28, with Reuters reporting DXY around 101.14 during European morning trading. The dollar entered a busy data week with support from the interest-rate backdrop, but currency-specific developments complicated the picture.
The main question is whether upcoming inflation and employment reports will justify keeping US monetary policy restrictive. Our assessment is that the dollar retains fundamental support, while fresh evidence is needed before treating its recent strength as a confirmed breakout.
DXY starts the week above Friday’s closing reference
Investing.com’s cash-index history recorded a Friday close of 100.97, compared with 100.22 on September 18. That represents a calculated weekly gain of approximately 0.75%, despite Friday’s retreat.
The distinction between a weekly gain and a daily pullback matters. They can coexist without establishing either a new decline or an uninterrupted advance. Monday’s separately reported quote also should not be combined with a different provider’s overnight percentage change to manufacture a precise session return.
This analysis refers to the cash Dollar Index. ICE dollar-index futures are related instruments with their own contract prices and expiry structure. Broker CFDs may also display different quotes. ICE describes the underlying index as a calculation using spot exchange rates from its component currencies.
Why interest rates remain central to the dollar outlook
The Federal Reserve raised its target range by a quarter percentage point to 3.75%–4.00% on September 16. Its statement described solid economic expansion, resilient domestic spending and elevated inflation. This is the confirmed policy backdrop; another increase at the next meeting remains an expectation, not an announced decision.
Our interpretation is that currency markets will focus on changes in the expected policy path. If incoming evidence causes investors to expect higher US rates relative to those elsewhere, dollar assets may become more attractive. If expectations already incorporate that outcome, however, an unsurprising release may produce little lasting movement.
A strong economic number is therefore not automatically a fresh bullish signal for DXY. Its significance depends on the market’s prior expectations, revisions to earlier data and the response in yields.
The same principle applies to weaker figures. One disappointing release may soften tightening expectations without overturning the broader economic picture. A more durable shift would require consistent evidence across inflation, spending and employment.
Oil and Treasury yields add a second layer
Reuters’ Monday market report put Brent’s intraday high around $107.16 a barrel and the US 30-year Treasury yield near 5.517%. The report linked renewed energy concerns to the setback in US–Iran diplomacy over the weekend.
Our analysis is that sustained energy disruption could support the dollar through several channels, including inflation concerns and demand for liquid assets during uncertainty. The effect is not uniform: energy costs also affect other economies and may influence their central banks.
The long-term Treasury yield deserves context. It reflects more than the next Fed decision, including expectations about growth, inflation and the compensation investors demand for holding longer maturities. A higher 30-year yield alone does not establish the exact size or timing of a future rate move.
For confirmation of a stronger dollar trend, we would look for a consistent response across US yields and the major currency pairs, rather than relying on one bond-market headline.
Why the euro and yen matter more than a broad dollar headline
ICE’s published DXY composition assigns 57.6% to the euro, 13.6% to the yen and 11.9% to sterling. The remaining currencies are the Canadian dollar, Swedish krona and Swiss franc. Consequently, the index is especially sensitive to EUR/USD; it does not directly include the Australian dollar, Chinese yuan or Indian rupee.
Reuters’ European-morning currency report placed EUR/USD near 1.1376 and GBP/USD around 1.3260.
Japan supplied a separate catalyst. Senior currency official Atsushi Mimura warned markets about excessive yen weakness, and the yen strengthened to around 156.75 per dollar following his remarks. He declined to specify whether intervention would follow. A verbal warning should not be described as confirmation of a new currency-market operation.
For DXY, this means euro weakness can coexist with a strengthening yen. The index summarizes those competing moves according to its weights. A bullish dollar view therefore should not be applied mechanically to every USD pair.
DXY technical levels to watch
The following areas are derived from completed cash-index sessions. Their interpretation is Pratik Algo’s analysis; previous highs and lows do not guarantee a reaction.
| DXY area | Historical basis | Interpretation |
|---|---|---|
| 101.23–101.31 | September 23 and 25 highs | Initial overhead area |
| 101.40 | September 24 high | Recent breakout reference |
| 100.87–101.00 | September 25 and 24 lows | Nearby support reference |
| 100.54–100.60 | September 23 low and 22 close | Lower reference if support fails |

Sustained acceptance above the recent high would strengthen the continuation case. Failure at resistance followed by a loss of nearby support would weaken it. Trading between those boundaries would favor a consolidation interpretation.
These levels are observation points, not automatic entry orders. This analysis does not claim confirmation from moving averages, RSI or exchange-wide spot volume.
Today’s speakers and the key US economic calendar
The Federal Reserve’s official calendar lists Michelle Bowman at 12:15 UTC and Lisa Cook at 17:25 UTC today. Bowman’s scheduled subject concerns banking supervision and regulation; Cook’s concerns AI and emerging technology. Neither event should be assumed to deliver a monetary-policy announcement.
| Date | Event | UTC | IST |
|---|---|---|---|
| Mon, Sep 28 | Bowman discussion | 12:15 | 17:45 |
| Mon, Sep 28 | ECB President Lagarde scheduled remarks | 13:30 | 19:00 |
| Mon, Sep 28 | Cook speech | 17:25 | 22:55 |
| Tue, Sep 29 | US JOLTS, August | 14:00 | 19:30 |
| Wed, Sep 30 | US August PCE / income and spending; Q2 GDP third estimate | 12:30 | 18:00 |
| Thu, Oct 1 | US ISM Manufacturing PMI, September | 14:00 | 19:30 |
| Fri, Oct 2 | US employment report, September | 12:30 | 18:00 |
Sources: Federal Reserve, BLS, BEA, ISM and Forex Factory. Scheduled times may change.
The ECB appearance also matters because the euro has the largest DXY weight. A change in expectations for European policy can move the index even without a new US release.
What the data could mean for DXY
PCE inflation and consumer spending: Wednesday’s BEA release will provide the August inflation, income and spending figures. Forex Factory’s calendar showed a 0.3% monthly core PCE forecast, compared with the previous 0.2% reading, when checked for this article. Those are forecast and prior values, not the new result.
In our assessment, an upside inflation surprise accompanied by resilient spending would make it harder to dismiss price pressure. A cooler inflation reading could reduce some support for tightening expectations, particularly if other details suggest demand is moderating. Revisions and the distinction between nominal and inflation-adjusted spending will also matter.
Employment: Tuesday’s JOLTS release and Friday’s employment report cover different aspects of the labor market. Openings, hiring, unemployment and wages should be evaluated together. A payroll headline can initially move the dollar, but downward revisions or a conflicting unemployment reading may complicate that first reaction.
Manufacturing: Thursday’s ISM report provides another check on activity and input costs. Our focus is whether demand indicators and price pressures point in the same direction. Stronger activity with stubborn costs would tell a different policy story from slowing orders accompanied by easing prices.
Conditional outlook for the next sessions
Our dollar outlook depends on three possible combinations:
- Continued support: Inflation and activity remain firm, US yield expectations strengthen relative to those abroad, and DXY gains broad confirmation from its largest components.
- Consolidation: Data broadly match expectations while different currencies respond to local developments. A firm macro backdrop may then coexist with limited index progress.
- Loss of momentum: Inflation cools, employment details soften or energy tensions ease enough to change policy expectations. A reversal in relative yields would make a dollar pullback more credible.
September 30 is also quarter-end. Portfolio rebalancing can sometimes produce currency flows that are unrelated to a new economic judgment. This is a consideration for interpreting price action, not a claim that a particular buying or selling flow has been verified today.
The key is whether a move survives the initial reaction and remains consistent with subsequent evidence. An intraday price spike and a durable change in the dollar outlook are different observations.
