Dollar Index Rises Despite Underlying Currency Weakness

The US Dollar Index (DXY) has been rising in recent weeks, but this upward trend may not necessarily indicate a stronger underlying currency. According to Detik Finance, geopolitical tensions and economic surprises have historically driven capital towards the greenback, pushing its value up during global events.

In early 2026, geopolitical tensions pushed the dollar index to a high of 100.64 in late March. Safe-haven demand continues to benefit the asset whenever international instability or financial market surprises occur. The index climbed past 101 by July 23, but despite this short-term upward momentum, its broader trajectory since the 2022 peak of 114.745 remains downward.

The continuous contract chart starting from 2008 demonstrates a long-term bullish trend, moving upward from an April 2008 low of 71.05 to its September 2022 high of 114.745, followed by the January 2026 low at 95.44. The structure of the Intercontinental Exchange's dollar index futures contract explains why index growth can occur alongside fiat currency weakness.

A heavy 57.6% weight is assigned to the euro, with the remainder divided among other fiat currencies. This means that the index merely measures relative performance against its constituents, and the dollar index can move higher even as the U.S. currency loses actual purchasing power.
