The US dollar soars to a seven-month high as rate hike expectations spur crowded long positions.

```

Bullish sentiment on the US dollar is rising across the board, with spot, derivatives, and positioning data all pointing to a short-term strong pattern.

On Tuesday (June 23), the Bloomberg Dollar Spot Index jumped to a seven-month high. The interest rate market has priced in nearly two Fed rate hikes (about 50 basis points) by early 2027, making the dollar one of the most sought-after assets in the market recently. Meanwhile, global risk events, such as the sharp decline of South Korean tech stocks, triggered a return of safe-haven funds, further strengthening the short-term support for the dollar.

However, despite the short-term strength, long-term structural concerns have not dissipated. The latest survey from the World Gold Council shows that 62% of global central banks expect the share of the US dollar in foreign exchange reserves to decrease over the next five years. This expectation stands in stark contrast to the current strong trend of the dollar and warrants long-term market attention.

Interest Rate Expectations Repriced, Dollar Index Hits Seven-Month High

The core driver of this round of dollar strength comes from a repricing in the interest rate market. The Bloomberg Dollar Spot Index has surged to its highest level since November 2025, signaling a significant shift in market expectations regarding the Fed’s monetary policy path.

Pricing in the interest rate derivatives market shows that traders now expect the Fed to raise rates by nearly two hikes (around 50 basis points in total) by early 2027. The formation of this expectation reflects a reassessment of US economic resilience and persistent inflation, which has also led to a notable unwinding of the previously prevailing rate-cut trades.

Options market and positioning data further confirm the breadth and depth of bullish sentiment on the dollar.

According to Bloomberg, the call premium on dollar options has risen to a high level, and the cost investors pay for protection against further dollar strength has climbed in tandem, indicating that the market’s pricing for upside dollar risks is turning bullish.

At the same time, leveraged long positions in the dollar have rebounded to levels seen at the beginning of 2025, showing that professional speculative funds are actively adding to bullish dollar positions, rather than following passively.

The resonance of these indicators means this round of dollar strength is not a short-lived move driven by a single factor but rather a trend with a solid positioning foundation.

In addition to interest rate expectations, the phase tightening of global risk sentiment has also provided extra short-term support for the dollar.

Recently, South Korean tech stocks have seen sharp declines, weakening risk appetite in Asian markets and prompting some funds to flow back into dollar assets to hedge against uncertainty. The dollar’s role as a traditional global safe-haven currency has been once again reinforced in such risk events, further boosting short-term demand.

Divergence Between Long-term Reserve Expectations and Short-term Strength

Despite the short-term strength, the dollar’s long-term status still faces structural challenges.

The latest survey from the World Gold Council shows that 62% of central banks worldwide expect the dollar’s share in FX reserves to decrease over the next five years.

This result indicates that sovereign institutions' confidence in the USD’s long-term reserve status is quietly diverging, standing in clear contrast to the prevailing bullish sentiment in current market trading.

It is noteworthy that adjustments to central banks' reserve structures are often slow and gradual, making it difficult to have a direct impact on exchange rates in the short term.
