Apr 9: The U.S. dollar weakened sharply, with the US Dollar Index falling by more than 1 percent amid rising geopolitical tensions, erasing all the gains it had built up earlier in 2026.

The decline reflects increasing caution among investors, who are reacting to global uncertainties by shifting away from the dollar. This change in sentiment has put pressure on the currency, reversing its earlier upward trend.

The US Dollar Index tracks the dollar’s performance against a basket of six major currencies. Among these, the Euro carries the highest weight, followed by the Japanese Yen, British Pound, Canadian Dollar, Swedish Krona, and Swiss Franc.

A fall in the index typically indicates a broad-based weakening of the U.S. currency against its global peers. The latest drop highlights how sensitive currency markets are to geopolitical developments and shifting investor confidence.

Analysts note that if uncertainty persists, the dollar could remain under pressure in the near term, with investors likely to continue seeking safer or alternative assets.
