Dollar gains on rate expectations, but upside may be limited

The US dollar is showing a more decisive response to changes in the interest-rate environment, and analysts at ANZ and Credit Agricole both see reasons for that momentum to continue in the short term.

Yet the two firms frame the move somewhat differently.

ANZ predicts that repricing at the front end of the yield curve will keep the greenback supported through October, though it adds that it is already “wary of chasing it”. That nuance is important.

According to ANZ, dollar short positions had been accumulating steadily before the recent move, so part of the current strength may come from covering those bets rather than a new wave of bullish positioning.

That leaves the underlying rate story carrying most of the weight. A more hawkish Federal Reserve outlook and higher short-end US yields continue to favour the dollar. Credit Agricole shares that view in its latest dollar analysis.

Credit Agricole argues that the dollar has begun to “close the gap” with its relative rate and yield advantage, yet still trades at a “huge discount” to those fundamentals.

From that standpoint, the bullish case for the dollar remains simple: US rates are still relatively attractive, and the currency may not fully reflect that edge yet.

The key question is how much room to run remains.

ANZ sees the long end of the Treasury curve as a potential drag. The firm notes: "Heavier issuance alongside rising US interest costs is increasingly USD-negative rather than supportive."

It still expects modest upside risk for the dollar over the coming week but warns that the DXY index may run into a ceiling near 101.

Credit Agricole meanwhile flags geopolitical risks as an unknown. The Trump-Xi summit and events in the Middle East could affect the dollar's safe-haven appeal, particularly if trade or geopolitical frictions flare up again.

Putting it all together, the fundamental backing for the dollar is still intact. But the easiest part of the rally may already be behind it.
