British Pound retreats as renewed Iran tensions boost demand for the Greenback
- GBP/USD falls as traders reassess US-Iran negotiations following renewed military escalation.
- Higher Oil prices continue to fuel inflation concerns linked to supply disruptions in the Strait of Hormuz.
- Recent softer UK labor market and inflation data prompted traders to scale back Bank of England (BoE) rate hike expectations.
The British Pound (GBP) weakens against the US Dollar (USD) on Tuesday as traders reassess ongoing US-Iran negotiations following renewed US military action in southern Iran. At the time of writing, GBP/USD is trading around 1.3444, down nearly 0.43% on the day.
Iran’s Foreign Ministry accused the United States of violating the ceasefire in the Hormozgan region and warned that Tehran “will respond and will not hesitate to defend itself,” in a statement shared by Iran’s IRIB broadcaster.
The latest developments dampened hopes for a quick end to the war in the Middle East, although diplomatic efforts between Washington and Tehran remain ongoing. Iran’s State TV reported that Parliament Speaker and chief negotiator Mohammad Bagher Ghalibaf returned to Tehran after consultations with Qatari officials in Doha.
Reports suggest the talks focused on the issue of frozen Iranian assets. Earlier in the day, Iran’s Tasnim News Agency, citing a source close to the negotiation team, reported that Tehran wants the US to release $24 billion in frozen Iranian funds as part of a potential deal. Iran is also seeking at least half of that amount to be released immediately after the agreement is announced.
Traders continue to favor the US Dollar amid ongoing uncertainty surrounding US-Iran negotiations. The US Dollar Index (DXY), which tracks the Greenback’s value against a basket of six major currencies, trades around 99.18, up nearly 0.21% on the day.
The Greenback is also supported by hawkish Federal Reserve (Fed) expectations. US inflation remains above the Fed’s 2% target, while higher Oil prices linked to supply disruptions in the Strait of Hormuz continue to add inflation pressure, leading traders to price in the possibility of a rate hike by year-end.
In contrast, traders have scaled back Bank of England (BoE) rate hike expectations following recent softer UK economic data, including weaker labor market and inflation figures, which have pushed UK gilt yields lower in recent days. However, markets still expect the BoE to raise interest rates, with upcoming speeches from central bank officials later this week likely to provide fresh policy guidance.
On the data front, US CB Consumer Confidence came in at 93.1 in May, down from 93.8 in April. Traders now await the US Personal Consumption Expenditures (PCE) inflation report on Thursday, while the UK economic calendar remains relatively light for the rest of the week.
Economic Indicator
Consumer Price Index (YoY)
The United Kingdom (UK) Consumer Price Index (CPI), released by the Office for National Statistics on a monthly basis, is a measure of consumer price inflation – the rate at which the prices of goods and services bought by households rise or fall – produced to international standards. It is the inflation measure used in the government’s target. The YoY reading compares prices in the reference month to a year earlier. Generally, a high reading is seen as bullish for the Pound Sterling (GBP), while a low reading is seen as bearish.

The Bank of England is tasked with keeping inflation, as measured by the headline Consumer Price Index (CPI) at around 2%, giving the monthly release its importance. An increase in inflation implies a quicker and sooner increase of interest rates or the reduction of bond-buying by the BOE, which means squeezing the supply of pounds. Conversely, a drop in the pace of price rises indicates looser monetary policy. A higher-than-expected result tends to be GBP bullish.
