The US dollar index has regained momentum recently, successively breaking through key psychological levels at 100 and 101 points. According to Wind data, as of the close on June 22nd, the dollar index stood at 101.0039 points, marking its highest level since May 2025. From May 1st to June 22nd this year, the index has risen by 2.96%.

Primary Drivers of the Rally

The core reason for this surge in the dollar index is that unexpectedly hawkish signals from the Federal Reserve have completely overturned market expectations for interest rate cuts. The dot plot from the Fed's June policy meeting indicated that nearly half of the committee members support raising rates within the year, fundamentally altering market sentiment. This shift has led to a rapid increase in short-term US Treasury yields and real interest rates, significantly enhancing the returns on dollar-denominated asset allocations. Concurrently, relatively robust US employment data and slower-than-expected declines in core inflation have created persistent price pressures, providing fundamental support for the Fed to maintain high interest rates or even restart its hiking cycle.

Additional Contributing Factors

Other factors are also propelling the dollar higher. The widening interest rate differentials between the US and Europe, as well as between the US and Japan, are causing global capital to flow back into US dollar assets. The concentrated unwinding of carry trades is further fueling dollar buying. Additionally, the safe-haven demand for the US dollar, spurred by uncertainties from international geopolitical conflicts, is contributing to the index's sustained upward movement.

Outlook for Dollar Strength

Will the dollar's strength persist? In the short term, the prevailing expectation of further Fed rate hikes is likely to support the dollar index around the 101 level, though the potential for continued significant gains appears limited. The medium-term trajectory will depend on the pace of US inflation decline and whether signals of economic cooling emerge. If US inflation shows a clear downward trend and employment weakens, the hawkish expectations will likely gradually shift, and the dollar will probably experience a choppy decline.

Impact on Other Assets

It is noteworthy that the recent strength of the dollar has also weighed on the performance of assets like gold. As of the June 22nd close, the international gold price has fallen by 9.53% since May 1st. In the near term, the dollar index is expected to maintain a relatively strong and volatile pattern. This will elevate global financing costs, suppress prices of assets such as gold and commodities, and continue to benefit dollar-denominated assets.
