United States Dollar Index holds above 101.00 following US strikes on Iran

  • US Dollar Index gains safe-haven support following US airstrikes on Iran over Strait of Hormuz ship attacks.
  • The Greenback's upside faces restraint as soft Nonfarm Payrolls data cooled market expectations for further interest rate hikes.
  • NY Fed President Williams showed less inflation anxiety, pointing to an expected and sustained decline in energy prices.

The US Dollar Index (DXY), which measures the value of the US Dollar (USD) against six major currencies, is holding gains for the second consecutive day and trading around 101.10 during the Asian session on Wednesday.

The Greenback receives support from safe-haven demand amid renewing geopolitical tensions. US airstrikes against Iran came in response to Iranian attacks on commercial vessels in the crucial Strait of Hormuz, including a Qatari LNG carrier and a Saudi oil tanker. The renewed hostility directly threatens a fragile, interim US-Iran peace pact, stoking fears of massive global energy disruptions as nervous shipping companies and local producers bypass the strategic waterway.

However, the upside of the US Dollar could be restrained due to cooling rate-hike expectations, a shift triggered by last week's weaker-than-expected Nonfarm Payrolls (NFP) data. According to LSEG data, market pricing for total Fed rate increases by December has dropped to roughly 26 basis points, down significantly from the 38 basis points projected just a week ago.

This shifting outlook is framed by recent commentary from key central bank officials. On Monday, Fed Governor Christopher Waller offered a cautious take on policy communication, noting that while forward guidance can be a valuable tool under the right circumstances, it can easily become problematic if used improperly. Conversely, New York Fed President John Williams struck a more reassuring tone on Tuesday, stating he has grown less anxious about domestic price pressures due to a recent retreat in energy prices, a downward trend he expects to continue.

Williams signals steady growth and balanced risks, keeping Dollar focus on data

Fed’s Williams delivers a moderately constructive but slightly softer message, with a 5.6/10 FXS Speechtracker score marginally below the 5.8/10 historical average, signaling a tone just under the established baseline. The emphasis on steady trend-like growth, a stable job market, retreating energy prices helping to cool inflation, and being near the peak impact of tariffs underscores confidence that monetary policy is “in a good place,” yet the acknowledgment that inflation is still quite high keeps a data-dependent bias intact for the Dollar. Overall, the remarks lean toward cautious optimism on inflation and growth, suggesting no imminent policy pivot but reinforcing that future moves hinge on incoming data and evolving risks.

The FXS Fed Sentiment Index slipped by 0.34 points to 125.38, indicating a modest pullback in perceived hawkishness relative to the prior reading. Despite the decline, the index remains firmly in hawkish territory above 100, showing that policy expectations are still skewed toward tighter conditions even as the tone of this speech softens slightly versus the FXS Speechtracker baseline.

US Dollar FAQs

The US Dollar (USD) is the official currency of the United States of America, and the ‘de facto’ currency of a significant number of other countries where it is found in circulation alongside local notes. It is the most heavily traded currency in the world, accounting for over 88% of all global foreign exchange turnover, or an average of $6.6 trillion in transactions per day, according to data from 2022. Following the second world war, the USD took over from the British Pound as the world’s reserve currency. For most of its history, the US Dollar was backed by Gold, until the Bretton Woods Agreement in 1971 when the Gold Standard went away.

The most important single factor impacting on the value of the US Dollar is monetary policy, which is shaped by the Federal Reserve (Fed). The Fed has two mandates: to achieve price stability (control inflation) and foster full employment. Its primary tool to achieve these two goals is by adjusting interest rates. When prices are rising too quickly and inflation is above the Fed’s 2% target, the Fed will raise rates, which helps the USD value. When inflation falls below 2% or the Unemployment Rate is too high, the Fed may lower interest rates, which weighs on the Greenback.

In extreme situations, the Federal Reserve can also print more Dollars and enact quantitative easing (QE). QE is the process by which the Fed substantially increases the flow of credit in a stuck financial system. It is a non-standard policy measure used when credit has dried up because banks will not lend to each other (out of the fear of counterparty default). It is a last resort when simply lowering interest rates is unlikely to achieve the necessary result. It was the Fed’s weapon of choice to combat the credit crunch that occurred during the Great Financial Crisis in 2008. It involves the Fed printing more Dollars and using them to buy US government bonds predominantly from financial institutions. QE usually leads to a weaker US Dollar.

Quantitative tightening (QT) is the reverse process whereby the Federal Reserve stops buying bonds from financial institutions and does not reinvest the principal from the bonds it holds maturing in new purchases. It is usually positive for the US Dollar.
