US Dollar Weakens as US-Iran Pause Unwinds Safe-Haven Trade; Fed Hike Back in Focus

The Quick Take

• US dollar weakened against major currencies after Washington paused bombing campaign against Iran
• Safe-haven demand for dollar unwound as risk appetite returned on geopolitical easing
• Markets now refocus attention on upcoming Federal Reserve interest rate decision

The US dollar fell against a basket of major currencies on Monday as news of a US-Iran ceasefire pause prompted traders to unwind safe-haven positions that had accumulated during the prior week's escalation. The DXY dollar index had reached a one-month high during peak hostilities as investors sought dollar-denominated assets; with risk appetite recovering, that defensive premium reversed. The euro, pound sterling, and Japanese yen all strengthened modestly, while commodity currencies — the Australian and Canadian dollars — benefited from the broader risk-on shift.

The shift in dollar dynamics redirects attention to the Federal Reserve, whose upcoming rate decision now looms as the dominant near-term catalyst for currency markets. Markets were already pricing a meaningful probability of a September rate hike before the Iran pause; with energy prices falling and the geopolitical risk premium easing, the Fed's path becomes more data-dependent than crisis-driven. Currency traders will parse this week's PCE inflation print and any Fed officials' commentary for clues on whether the hike probability — currently around 82% according to futures markets — shifts further.

For EM currencies and Asian FX, the dollar's weakness offers a temporary reprieve. The Indian rupee, Indonesian rupiah, and Thai baht had all faced depreciation pressure in prior weeks as dollar strength compounded local current-account dynamics. A softer dollar environment, if sustained, would ease import cost burdens and reduce the urgency for EM central banks to raise rates defensively. However, the structural dollar bid from US rate expectations has not disappeared — it has merely taken a pause alongside the geopolitical risk trade.
