Trading around 101.80 in Tuesday’s European session, the US Dollar Index (DXY) is retreating after modest gains. The index tracks the US Dollar (USD) against a basket of six major currencies.
Holding above the 50-day Exponential Moving Average (EMA) gives DXY a mildly positive short-term outlook, although the nine-day EMA is limiting gains as the nearest resistance. Momentum remains steady rather than overbought, with the 14-day Relative Strength Index (RSI) at around 55. Meanwhile, the latest FXS Fed Sentiment Index readings, near 127.51, suggest that broader policy expectations are no longer providing aggressive support, restraining the upside.

On the daily chart, technical analysis also shows the dollar index testing the ascending channel’s lower boundary. A bullish rebound from this trendline support could restore the uptrend, whereas a failure to hold the level would risk a bearish breakdown.
A recovery in the US Dollar Index could bring the nine-day EMA at 101.98, its nearest resistance, into focus. Clearing this short-term moving average would reinforce the bullish bias and support a test of the 18-month high at 102.94, recorded on 14 October. Beyond that lies the ascending wedge’s upper boundary at 103.90.
The first support under test is the ascending channel’s lower boundary, around 101.70, with the 50-day EMA at 100.94 next in line. A deeper fall in the US Dollar Index would leave the five-month low of 98.56, set on 20 August, exposed.
At 5.6/10 on the FXS Speechtracker, Fed Chair Warsh’s speech falls slightly below the historical average of 6.1/10. The reading signals caution despite positive remarks about structural growth and a surge in investment. By acknowledging being “over-scarred from the global financial crisis”, Warsh reveals a risk-conscious bias that moderates the hawkish implications of his emphasis on price stability and the forthcoming “crystallizing” meetings in October and December. His attention to AI as a driver of demand and to tail risks for financial stability indicates that the Fed is receptive to structural optimism, but is not prepared to commit in advance to a policy course for the remainder of 2026.
A move of 0.00 points left the FXS Fed Sentiment Index unchanged at a still-elevated 127.51. This suggests that, despite the speech’s slightly softer tone relative to the FXS Speechtracker’s established baseline, the Fed remains firmly hawkish. For markets, the combination of an elevated index reading and guidance that avoids firm commitments suggests that expectations of persistently restrictive policy continue to support the Dollar. Data and AI-related developments will nevertheless be central to the next policy “crystallizing” moments.

As well as being the official currency of the United States of America, the US Dollar (USD) acts as the ‘de facto’ currency in a significant number of other countries, circulating alongside their local banknotes. No currency is traded more heavily worldwide: according to 2022 data, it accounts for over 88% of global foreign exchange turnover, equivalent to average daily transactions of $6.6 trillion. After the Second World War, the USD replaced the British Pound as the world’s reserve currency. Gold backed the US Dollar for most of its history, until the Bretton Woods Agreement in 1971 brought the Gold Standard to an end.
Monetary policy, set by the Federal Reserve (Fed), is the single most significant influence on the US Dollar’s value. The Fed’s dual mandate is to maintain price stability by controlling inflation and to promote full employment. Adjustments to interest rates are its main means of pursuing both objectives. If prices climb too rapidly and inflation exceeds the Fed’s 2% target, it will increase interest rates, supporting the USD. Conversely, inflation below 2% or an excessively high unemployment rate may prompt the Fed to cut rates, putting pressure on the Greenback.
Under extreme conditions, the Federal Reserve may also create more Dollars through quantitative easing (QE). This process substantially expands the supply of credit within a financial system that is no longer functioning smoothly. As an unconventional policy measure, QE is used when credit has dried up because banks, fearing counterparty defaults, are unwilling to lend to one another. It serves as a last resort when interest rate cuts alone are unlikely to deliver the required outcome. During the Great Financial Crisis in 2008, QE was the Fed’s preferred tool for tackling the credit crunch. The process involves creating additional Dollars to purchase US government bonds, mainly from financial institutions. The US Dollar generally weakens as a result of QE.
The reverse process, quantitative tightening (QT), involves the Federal Reserve halting bond purchases from financial institutions and allowing its existing bonds to mature without reinvesting the principal in further purchases. This is generally supportive of the US Dollar.
