Renewed tensions between the United States and Iran have triggered significant moves across major currency pairs and commodity markets. The GBP/USD pair opened the week with a bearish gap, retreating from a two-month high near 1.3600 and trading just below the 1.3500 mark, down over 0.15% for the day. This decline was attributed to a shift in global risk sentiment following Iran's closure of the Strait of Hormuz and the US naval blockade of Iranian ports, which dampened hopes for further peace talks before the ceasefire ends on April 21 [1]. Iran's official IRNA news agency reported that Tehran would not participate in a second round of talks with the US, while President Trump threatened to target Iranian infrastructure if Iran did not agree to US terms [1][2][3].
The EUR/USD pair also opened lower, trading around 1.1760, as the US Dollar drew support from heightened safe-haven demand amid escalating Middle East tensions. Iran refused to resume talks, citing 'unrealistic expectations,' and kept the Strait of Hormuz blocked after briefly reopening it over the weekend. President Trump confirmed US representatives would travel to Islamabad for negotiations but reiterated threats against Iranian infrastructure [2]. The renewed blockade has fueled concerns about stagflation in the Eurozone, with traders increasing bets on a potential ECB rate hike this year. ECB President Christine Lagarde acknowledged elevated energy costs are impacting Eurozone growth, but did not signal imminent rate hikes [2].
The USD/JPY pair held positive ground near 159.10, with the US Dollar strengthening against the Japanese Yen. Iran denied participation in new peace talks, hours after President Trump announced negotiators would head to Pakistan for a second round. The US Navy reportedly fired upon and seized an Iranian-flagged cargo ship, and Tehran warned that ships approaching the strait would be treated as violating the ceasefire. Several vessels abandoned crossings shortly after Tehran had said the waterway was open [3]. Japanese authorities, including Finance Minister Satsuki Katayama, indicated readiness for 'bold' action to limit JPY losses, following close discussions with US Treasury Secretary Scott Bessent [3].
Across all sources, the escalation in US-Iran tensions has led to a sharp rally in crude oil prices, reviving inflationary concerns and pushing US bond yields higher, further supporting the US Dollar [1]. However, USD bulls appear cautious due to diminishing odds for a Federal Reserve rate hike, contrasting with bets on a Bank of England rate hike, which provides some support to the GBP [1]. Attention is now turning to Tuesday's US Retail Sales data, expected to rise 1.3% MoM in March after 0.6% in February [2].
CONCLUSION
The renewed US-Iran tensions have driven a flight to safety, strengthening the US Dollar and pressuring the GBP, EUR, and JPY. Crude oil prices surged, fueling inflation concerns and higher US bond yields. While central banks' policy outlooks remain in focus, the immediate market impact is high, with risk sentiment dominating currency and commodity moves.
