Buying interest around 101.60-101.55 on Monday is helping the US Dollar Index (DXY) extend Friday’s rebound from close to a three-week low. The index, which measures the Greenback against a basket of currencies, retains small intraday gains in early European trading. However, further buying remains limited and DXY is still below 102.00, with traders awaiting clearer guidance on the Federal Reserve’s (Fed) policy outlook.

Wednesday’s conclusion of the two-day FOMC meeting therefore remains the main focus, alongside Fed Chair Kevin Warsh’s remarks at the subsequent press conference. Thursday’s Advance US Q3 GDP report and Personal Consumption Expenditures (PCE) Price Index will also be important in shaping the DXY’s next directional move.
Meanwhile, support for the US Dollar (USD) comes from growing expectations that the US central bank will increase borrowing costs in response to inflation risks associated with elevated crude oil prices. Tensions between the Iran-backed Houthis in Yemen and Saudi Arabia also keep geopolitical risks in focus, lending further support to the safe-haven Greenback and the DXY.
Trading above both the 200-period Simple Moving Average (SMA) on the 4-hour chart and the 38.2% Fibonacci retracement of the September-October advance leaves the index with a mildly bullish bias. The Moving Average Convergence Divergence (MACD) line is also hovering just above zero. Meanwhile, a Relative Strength Index (RSI) reading near 50 points to neutral but stable momentum.
Provided immediate support holds at 101.30, where the 38.2% retracement coincides with the 200-period SMA on the 4-hour chart, the technical picture suggests scope for the DXY to edge higher. A decisive breach of this support confluence would instead bring the lower Fibonacci levels at 100.78 and 100.27 into view. Broader structural demand lies further down towards 99.53 and 98.60.
Any advance would first encounter resistance at 101.93, the 23.6% Fibonacci retracement, before the more substantial barrier around the cycle high anchor at 102.96. Sustained buying above 103.00 would be regarded as a new trigger for bullish traders, paving the way for a resumption of the established uptrend from September’s monthly swing low.

As well as being the official currency of the United States of America, the US Dollar (USD) circulates alongside local banknotes as the ‘de facto’ currency in a significant number of other countries. No currency is traded more widely: according to 2022 data, it accounts for over 88% of global foreign exchange turnover, equivalent to average daily transactions of $6.6 trillion. The USD replaced the British Pound as the world’s reserve currency after the Second World War. 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 biggest influence on the US Dollar’s value. Achieving price stability by controlling inflation and promoting full employment are the Fed’s two mandates. Adjustments to interest rates are its main means of pursuing these goals. The Fed raises rates when prices increase too rapidly and inflation exceeds its 2% target, a move that supports the USD. Conversely, inflation below 2% or an excessively high Unemployment Rate may prompt the Fed to cut interest rates, putting pressure on the Greenback.
The Federal Reserve can resort to printing additional Dollars and introducing quantitative easing (QE) in extreme circumstances. Through QE, the Fed sharply expands the supply of credit within a financial system that has become blocked. This unconventional policy is used when credit dries up as banks become unwilling to lend to one another for fear of counterparty default. It is a measure of last resort when interest rate cuts alone are unlikely to deliver the required outcome. During the Great Financial Crisis in 2008, the Fed chose QE to tackle the credit crunch. Under the programme, newly printed Dollars are used to purchase US government bonds, mainly from financial institutions. The US Dollar typically weakens as a result of QE.
Reversing that process, quantitative tightening (QT) sees the Federal Reserve cease bond purchases from financial institutions and refrain from reinvesting the principal of maturing bond holdings in fresh purchases. This policy is generally supportive of the US Dollar.
