The US Dollar Index (DXY), which tracks the performance of the US Dollar (USD) against six major currencies, has failed to break above 104.50 on earlier attempts. The index trades slightly above 104.00 at the time of writing os Tuesday, while markets assess two main stories. The first market driver comes from United States (US) President Donald Trump, who issued “secondary tariffs” of 25% on all goods from countries that still buy Oil from Venezuela. Trump eased off on the size and broadness of reciprocal tariffs that are set to kick in on April 2 and commented about adding more targeted tariffs on cars, aluminum, pharmaceuticals, chips and lumber, Bloomberg reports.
Meanwhile, markets are looking for comments from the European bloc after a US news editor got invited by mistake to a Signal’s chat group with several Trump administration officials, including Vice President JD Vance, National Security Advisor Michael Waltz, Defense Secretary Pete Hegseth and Secretary of State Marco Rubio, among others. Comments from JD Vance towards Europe painted a clear picture of what and how he would like to see the EU being targeted with tariffs to pay for the US military actions against Houthi rebels, the Financial Times reports. The issue not only raises questions on the stance of the US towards Europe but also about security problems as a third-party chat application was used to discuss US military operations, weapon inventories and tactical plans.
The US Dollar Index (DXY) faces some selling pressure on Tuesday after a very early test to break above 104.50. The turnaround comes after US President Donald Trump issued more concerns and constraints on tariffs ahead of the deadline on April 2. The leaked messages from US Vice President JD Vance on Europe and other trade partners are an issue of concern for markets.
With the weekly close above 104.00 last week, a large sprint higher towards the 105.00 round level could still occur, with the 200-day Simple Moving Average (SMA) converging at that point and reinforcing this area as a strong resistance at 104.97. Once broken through that zone, a string of pivotal levels, such as 105.53 and 105.89, could limit the upward momentum.
On the downside, the 104.00 round level could be considered the first nearby support. If that does not hold, the DXY risks falling back into that March range between 104.00 and 103.00. Once the lower end at 103.00 gives way, watch out for 101.90 on the downside.
US Dollar Index: Daily Chart
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.
