On March 6, the US dollar index continued to decline, approaching the 104 mark, reaching its lowest level since November 2023. Over the past three days, the index has fallen nearly 3%, with a growing bearish sentiment towards the dollar. Analysts believe that rising expectations of a US economic slowdown and increased confidence in the European economy are shifting market fundamentals from "strong US, weak Europe" to "weak US, strong Europe," causing the dollar index to continue its downward trend.
Why is the US dollar index continuously declining?
Analysis points out two main factors contributing to the dollar's weakness:
- Rising expectations of a US economic slowdown
Recent US economic data has been weak, and the Trump administration's tariffs on Canadian and Mexican goods have heightened concerns about a US economic recession. Consumer and business confidence has waned, deepening pessimism about future economic prospects, which is putting pressure on the dollar. - Increased confidence in the European economy
Compared to the US economic weakness, optimism in the European market is growing. German candidate Chancellor Scholz announced plans to relax the "debt brake" mechanism, allowing defense spending to exceed 1% of GDP, along with a plan to establish a 500 billion euro infrastructure fund to support construction over the next decade. Additionally, the EU has proposed an 800 billion euro military investment plan, allowing members to raise defense spending to 1.5% of GDP. These measures boost market confidence in the European economic recovery, strengthening the euro and further depressing the dollar index.
What is the future outlook for the US dollar?
In the short term, the dollar index's performance will continue to depend on the euro's movement. Currently, there is optimism about going long on the euro. However, the euro's rise faces challenges. MUFG analyst Derek Halpenny pointed out that after Germany plans to increase defense and infrastructure spending, the US may impose tariffs on eurozone goods, which could limit further euro gains.
In the long term, the dollar index remains dependent on the US economic performance. ITR Economics economist Connor Lokar believes tariff policies may not lead to a US recession, "Trade doesn't constitute a large share of the US GDP, and the US economy will ultimately continue to expand."
Overall, in the short term, the dollar index's movement is primarily influenced by European economic developments and market sentiment, while the long-term trend hinges on the actual performance of the US economy. If US economic data continues to be weak, the dollar may face greater downward pressure, and further strengthening of the euro may accelerate the dollar's depreciation.
