Why is the US dollar falling by record levels in 2025?

The US dollar has recorded its worst first half since 1973, with the dollar index falling 10.8% in H1 2025, primarily due to President Trump's unpredictable economic policies, including tariff wars and tax bills projected to significantly increase national debt. This policy uncertainty has eroded the dollar's safe-haven status, prompting an exodus from US assets, a Moody's downgrade, and a reduced US growth outlook, while boosting gold and the euro. Consequently, investors are increasingly wary of US assets, challenging the dollar's long-term stability and its role as the global reserve currency.

Analysis

The U.S. dollar is experiencing a significant and historic sell-off, with the dollar index declining 10.8% in the first half of 2025, its worst performance for that period since 1973. This downturn is directly linked to a crisis of confidence in U.S. economic policy, driven by unpredictable tariff implementations and a proposed tax bill expected to add trillions to the national debt. The market reaction has been severe, with over $5 trillion erased from the S&P 500 following the initial tariff announcement and a subsequent sovereign credit downgrade by Moody's in May. Fiscal concerns are mounting, as the Congressional Budget Office projects the new legislation will increase federal debt by $3.3 trillion by 2034, pushing the debt-to-GDP ratio beyond its current 124%. Consequently, capital is flowing out of U.S. assets, including a notable exodus from the Treasury market, and into alternatives. Gold has reached record highs, and the euro has appreciated 13% against the dollar. This environment, coupled with expectations of 2-3 Federal Reserve interest rate cuts by year-end, suggests a sustained period of dollar weakness and reduced appeal for U.S. assets as a global safe haven.

Key Decisions for Investors

• Consider reducing net long exposure to the US dollar or implementing currency hedges, as ongoing fiscal policy uncertainty and dovetailed monetary easing are likely to maintain downward pressure on the currency.
• Evaluate overweighting non-US assets, particularly European equities and sovereign bonds, which are benefiting from capital rotation away from the US and a strengthening euro.
• Maintain or increase strategic allocations to gold, which is acting as a primary beneficiary of the dollar's declining safe-haven status and continued central bank demand.
• Closely monitor the legislative progress of the proposed US tax bill and Federal Reserve communications, as these events are key catalysts that could accelerate the current market trends.
