Dollar’s Steep Slide in 2025 Signals Deep Shifts in Global Finance

The US dollar has dropped more than 10% in the first half of 2025, marking its worst six-month performance since 1973, according to official data from the US Treasury and Federal Reserve.

The dollar index, which tracks the currency against a basket of major peers, closed June at 97.26 after five straight months of decline. This sharp drop has sent shockwaves through global markets and forced investors, businesses, and policymakers to reassess their strategies.

Several hard facts explain this historic decline. The US national debt reached $36.2 trillion in May 2025, up 31% since 2019, according to US government data. The debt now equals $106,000 per US resident.

This rapid rise in government borrowing has raised concerns among investors about the long-term stability of US finances. As a result, demand for US Treasury bonds has weakened, putting further pressure on the dollar.

At the same time, the Federal Reserve kept its main interest rate steady at 4.25–4.50% through four meetings in 2025. However, traders expect the Fed to cut rates later this year, as inflation has cooled and consumer spending has slowed.

Lower US rates make American assets less attractive to global investors, who seek higher returns elsewhere. This shift has led to capital moving out of the dollar and into other currencies, such as the euro and the Brazilian real.

Official data from the International Monetary Fund shows the dollar’s share of global currency reserves fell to 57.39% in the third quarter of 2024, its lowest in two decades.

Global Shift Away from Dollar Gains Momentum Amid Trade Tensions

Central banks around the world have started to diversify their reserves, reducing their reliance on the dollar. The euro’s share rose to 20.02% in the same period, reflecting this trend.

Trade tensions have added to the dollar’s woes. The US administration has imposed new tariffs and ended talks with Canada over digital taxes, raising fears of more trade barriers.

These moves have unsettled markets and led some investors to question the reliability of US economic policy. The Brazilian real, for example, has gained ground.

The average exchange rate in 2025 was 1 US dollar to 5.77 reais, compared to over 6 reais at the start of the year. This appreciation reflects both Brazil’s relatively high interest rates and the weakening dollar.

The dollar’s fall matters because it changes the cost of doing business worldwide. US imports become more expensive, while American exports become cheaper.

For global investors, the shift reduces the value of dollar-denominated assets. For policymakers, it signals a need to rethink strategies as the dollar’s dominance faces new challenges.
