GBP/USD falls 0.2% to $1.3423 as Middle East tensions lift dollar

The pound dropped more than 0.2 percent to $1.3423 Monday as US-Iran military strikes and stronger-than-expected US manufacturing data drove safe-haven demand for the dollar, extending a risk-off shift across currency markets.

"The dollar bid reflects a double catalyst — geopolitical risk premium from the Middle East escalation layered on top of a surprisingly strong Chicago PMI print," said Elena Fischer, geopolitical risk analyst at Edgen. "Markets are pricing a higher probability of sustained conflict that keeps energy prices elevated."

The US Dollar Index climbed 0.14 percent to 99.01, while WTI crude surged 3.78 percent to the $89-a-barrel range after the US struck Iranian military sites Saturday and Tehran retaliated, according to reports. Gold fell 0.86 percent to below $4,500 an ounce as rising energy prices pushed Treasury yields and the greenback higher. The Chicago PMI jumped to 62.7 from 49.2 in the prior month, well into expansionary territory and well above consensus estimates.

The pound has now erased nearly all its gains from the brief ceasefire period in late April, when GBP/USD traded above $1.36. With the Fed's December meeting still a coin toss between a hold and a hike per CME FedWatch, and the Bank of England's Mann warning that the era of low inflation has "run out," further dollar strength could push cable toward the $1.33 support level last tested in mid-March.

The US-Iran escalation marks the most significant direct military exchange between the two countries since the conflict began. Defense Secretary Hegseth said the US is ready to restart strikes if no deal emerges, while President Trump said the administration is in "no hurry" to reach one. The lack of a clear off-ramp keeps the geopolitical risk premium embedded in oil and the dollar.

The last time the US and Iran exchanged direct strikes in April, WTI briefly touched $95 before settling near $87, while the dollar index gained 1.2 percent over a two-week period. GBP/USD fell 2.8 percent during that same window, according to Bloomberg data. The current move has been more contained — cable is down about 0.6 percent from its pre-escalation level — suggesting markets are still weighing the probability of a broader conflict.

Rate Differentials Widen as Data Diverges

The dollar's strength Monday was amplified by the stark contrast between US and European economic data. The Chicago PMI's surge to 62.7 — its highest reading in over a year — came on the same day German preliminary CPI unexpectedly contracted 0.2 percent month-over-month, with headline inflation slowing to 2.6 percent year-over-year. Canadian GDP also surprised to the downside, contracting 0.1 percent in March.

This data divergence reinforces the dollar's yield advantage. The 2-year Treasury yield rose 2.5 basis points to 4.17 percent, while the 10-year yield climbed to 4.46 percent. The US-EU rate differential now stands at roughly 180 basis points on the 2-year tenor, making dollar-denominated assets more attractive to yield-seeking capital.

Oil Shock Complicates Central Bank Calculus

The rise in WTI above $89 introduces a new variable for central banks already navigating an uncertain inflation outlook. Federal Reserve officials offered diverging views Monday: Bowman warned against raising rates to react to "temporarily elevated price inflation," while Schmid cautioned against viewing the oil shock as transitory. Daly said the Fed should not restore price stability by "harming the economy."

For the Bank of England, the implications are more direct. The UK is a net importer of energy, and each $10 increase in Brent adds roughly 0.3 percentage points to UK CPI, according to BOE estimates. With UK inflation still above target, a sustained oil rally would complicate any case for rate cuts this year. Markets are currently pricing a 45 percent probability of a BOE cut in August, down from 55 percent before the escalation.

The pound's fate now hinges on two variables: whether Middle East tensions de-escalate — which would remove the dollar's geopolitical bid — and whether this week's US non-farm payrolls report on Friday confirms the strength signaled by the Chicago PMI. A payrolls print above 200,000 would likely accelerate dollar buying and push GBP/USD toward $1.33.
