US Dollar Index Today, Sep 23: DXY Tests 101 After PMI

The US Dollar Index today is near 101.00, with the provider recording a session high of 101.07. The dollar is holding near the upper end of its displayed range following stronger-than-expected US business surveys.

For the dollar outlook, the question has shifted from what the PMI release might show to whether the market can retain its gains after the results. Rising Treasury yields and fresh Federal Reserve comments make the interest-rate response especially relevant.

US PMI results beat expectations

The flash September surveys, released at 13:45 UTC, showed stronger readings in both major sectors:

These are preliminary survey results and can be revised. A reading above 50 indicates expansion compared with the previous month; it is not a percentage growth rate. PMI results and consensus.

Reuters reported that the composite output index rose to 58.4 from 56.0, its strongest reading since July 2021. The report also highlighted increasing input costs and supply constraints. Reuters report on US activity.

Our assessment: this combination is more challenging for the inflation outlook than stronger activity accompanied by easing costs. It can encourage markets to expect tighter policy, supporting dollar demand through interest-rate expectations. However, a survey surprise does not mechanically determine the next Fed decision.

Barr’s comments reinforce the focus on further tightening

The Federal Reserve raised its target range by 25 basis points to 3.75%–4.00% on September 16, describing inflation as elevated and activity as expanding solidly. Federal Reserve statement.

On September 23, Fed Governor Michael Barr said further policy adjustments would likely be needed to bring inflation back to target. He described inflation risks as having increased while labour-market risks had receded. Reuters report on Barr’s remarks.

Our interpretation is that today’s surveys and Barr’s remarks point in a similar direction for policy expectations. That supports the dollar’s fundamental case, but does not establish the timing or size of another rate increase.

A sustained currency advance would need investors to keep that view after digesting the details. If yields retreat despite strong headlines, it would suggest that some of the expected policy response is already reflected in prices.

Why the rise in Treasury yields matters

The retrieved 10-year yield above 5% provides another measure of the market’s response. Higher US yields can improve the relative appeal of dollar assets, particularly when the move exceeds changes in comparable overseas yields.

The relationship is conditional. Long-term yields also incorporate inflation expectations, term premiums and other influences; their rise cannot be attributed entirely to the expected Fed path.

For today’s analysis, the useful observation is whether the dollar and yields retain their advances together. A divergence would warrant more caution about interpreting the move as a durable change in expectations.

Europe’s stronger data also belongs in the picture

The euro area’s flash composite PMI increased to 53.1 from 52.0, beating a Reuters poll forecast of 51.7. European activity therefore also delivered a positive surprise. Reuters euro-area PMI report.

This matters because the euro has a 57.6% weight in ICE’s six-currency Dollar Index. ICE index composition.

Our assessment is that the dollar’s performance depends on relative developments, not US data alone. A stronger European outlook could support the euro if it changes expectations for European policy sufficiently. Watching EUR/USD alongside Treasury yields helps distinguish broad dollar strength from a move concentrated in one major component.

DXY support and resistance references

These are observed price references and a round number, not calculated moving averages or guaranteed turning points. Current DXY snapshot, Dated DXY history.

Continuation scenario: sustained trading above the session peak, supported by firm yields, would strengthen the case for an extension.

Consolidation scenario: repeated reversals around the round number would suggest that the initial repricing is settling into a range.

Pullback scenario: losing 100.70 would bring 100.56 back into focus. Further weakness would make the session low more relevant.

These scenarios carry no assigned probabilities and are not trade-entry instructions.

What to watch next

Chicago Fed President Austan Goolsbee is scheduled to speak at 16:00 UTC. The calendar displayed Jakarta time, UTC+7; seven hours have been subtracted. Schedules can change. Today’s calendar.

The main question is whether subsequent commentary reinforces the case for tighter policy or introduces qualifications. Any remarks should be assessed as one official’s view, rather than a new committee decision.

For the rest of the session, our focus is on the durability of the dollar’s move, the behaviour of Treasury yields and the euro’s response. Holding gains after the news would provide more convincing evidence than the first price spike.
