LONDON, May 21 (Reuters) – The pound was steady against the dollar on Thursday as broader currency markets focused on developments in the Iran war, while traders digested ​some worse-than-expected surveys of British business activity.

Sterling was flat at $1.3437. ‌Against the euro, the pound was 0.13% higher at 86.42.

A survey on Thursday showed British companies suffering their most widespread drop in activity in more than a year due to the economic fallout from the Iran war and political ‌uncertainty ​at home.

Data company S&P Global’s preliminary UK Composite ⁠Purchasing Managers’ Index for ⁠May tumbled to 48.5, from 52.6 in April, its first sub-50.0 reading since April 2025 and far below the 51.6 median in a Reuters poll. A PMI below 50.0 indicates slowing activity.

The ​figure overshadowed recent positive British data reads, including strong Q1 GDP figures last week and inflation figures on Wednesday.

April’s CPI figures ⁠on Wednesday showed inflation came in at ⁠2.8% in April, down from 3.3% in March and ​below economists’ expectations for a 3% reading.

“It’s a case of what ​might have been for the UK,” said Henry Cook, senior ‌economist at MUFG Bank.

“In a different world, we’d be looking at that Q1 GDP number and saying this is a great platform for growth ahead, yesterday’s inflation number would have been potentially bang on ⁠target… we’d be looking at a couple of BoE rate cuts this year.”

“That’s a different world,” he said, highlighting the ongoing closure of the Strait ⁠of Hormuz that ‌has choked the global flow of oil and ⁠led to a surge in energy prices, upending ​central bank ‌expectations and the global growth outlook.

In April, the ​Bank of ⁠England kept interest rates on hold and assessed the potential economic impacts of the U.S.-Israeli war on Iran, one of which could necessitate a “forceful” increase in borrowing costs.

Even so, money market bets indicate an 86% chance of no change at the BoE’s next meeting on June 18.
