Pound Strengthens as Dollar Sheds Value on Signs of Iran-U.S. Deal; Oil Slides

Markets rally on reports of progress toward a Gulf agreement and a possible reopening of the Strait of Hormuz, lifting sterling and the euro amid broader dollar weakness

By Maya Rios

Sterling and the euro climbed on Wednesday after reports suggested progress toward an agreement between Washington and Tehran and Iran signalled the Strait of Hormuz could allow safe passage. The moves reflected broad dollar weakness, driven by diplomatic developments that also pressured oil prices. Attention now shifts to U.S. inventory data and domestic political developments in the U.K. that could reframe risk sentiment.

Pound Strengthens as Dollar Sheds Value on Signs of Iran-U.S. Deal; Oil Slides

Key Points

  • Diplomatic signals from Iran and reports of an impending U.S.-Iran memorandum of understanding led to a broad dollar sell-off, lifting sterling and the euro.
  • GBP/USD rose to 1.3615 and EUR/USD to 1.1755 by 08:25 ET (12:25 GMT), movements driven mainly by dollar weakness rather than independent currency strength.
  • Market focus shifts to U.S. EIA inventory data and UK local elections, both of which could quickly alter risk sentiment and affect oil, bond and currency markets.

Sterling and the euro advanced Wednesday as the dollar weakened sharply following diplomatic signals from Iran and reports that the United States and Tehran are edging closer to a deal to end hostilities in the Gulf. The moves sparked a broad risk-on reaction in markets and a pronounced decline in oil prices.

By 08:25 ET (12:25 GMT), GBP/USD had risen 0.42% to 1.3615, while EUR/USD was up 0.53% at 1.1755. Market participants said these moves were predominantly driven by dollar selling rather than isolated strength in the individual currencies.

State media reported that Iran's Islamic Revolutionary Guard Corps navy said safe transit through the Strait of Hormuz was possible following the neutralisation of what it called "aggressor threats." This statement came hours after President Trump paused "Project Freedom," citing "great progress" toward a "complete and final agreement."

Subsequent reporting by Axios, citing two U.S. officials and two additional sources briefed on the matter, indicated the two sides are close to finalising a one-page memorandum of understanding. Under the reported terms, Iran would agree to a moratorium on nuclear enrichment in return for U.S. sanctions relief and the release of frozen funds. A Pakistani source involved in the discussions told Reuters, "We will close this very soon. We are getting close."

Despite the reports, obstacles to a durable dollar recovery remain. President Trump warned on Truth Social that bombing would resume "at a much higher level and intensity" if Iran rejected the terms, and the parties had not yet signed a permanent agreement.

Near-term market attention is likely to centre on U.S. Energy Information Administration weekly inventory data due at 16:30 CET. The market consensus expects a 2.4 million barrel drawdown following the prior week's 6.2 million barrel fall. Traders noted that a larger-than-expected decline in inventories could quickly reverse the risk rally that accompanied the diplomatic headlines. April ADP employment data are also scheduled, with consensus at +120,000.

Market strategists at ING flagged potential technical support for the U.S. dollar index (DXY) around 97.65-97.75, which could limit further dollar losses if those levels hold.

The euro has lagged on the crosses, with EUR/GBP and EUR/CHF movements reflecting two months of negative eurozone data surprises and the impact of elevated energy costs. That underperformance has coincided with only modest risk-driven demand for the euro and with market expectations that the European Central Bank may deliver a precautionary rate increase in June. Two-year inflation swaps are trading at 3.03%, a factor that has provided some support for the currency.

ING analysts suggested they do not expect EUR/USD to break convincingly above 1.18 and said they would not rule out a move back toward 1.1700.

Sterling's relative resilience has attracted attention as GBP/USD held up even while U.K. gilt yields traded at multi-year highs ahead of local elections on Thursday. ING's rates strategy team noted the U.K. swap spread has remained stable, indicating the recent sell-off in gilts has not been driven solely by election-related factors.

Political risk in the U.K. remains a potential market mover. Analysts warned that a strong result by the Conservative Party against Labour on Thursday could precipitate a leadership challenge, introducing fresh uncertainty for gilt markets and the pound. Technical support for EUR/GBP sits at 0.8600-0.8610 and is expected to hold, according to market commentary.


Market snapshot

  • GBP/USD: +0.42% to 1.3615 (08:25 ET / 12:25 GMT)
  • EUR/USD: +0.53% to 1.1755 (08:25 ET / 12:25 GMT)
  • Key upcoming data: U.S. EIA weekly inventories at 16:30 CET (consensus -2.4m barrels); April ADP employment (consensus +120,000)

The evolving diplomatic developments around Iran and the United States, combined with imminent U.S. inventory figures and U.K. political events, leave markets sensitive to data and headlines that could either reinforce the current risk rally or trigger a rapid reversal.

Risks

  • A larger-than-expected drawdown in U.S. oil inventories could reverse the risk rally and push oil prices higher, affecting energy and commodity-sensitive assets.
  • The diplomatic process remains incomplete and fragile - President Trump's warning that bombing could resume if Iran rejects terms underscores the risk of renewed military escalation, which would shift markets abruptly.
  • U.K. political developments following local elections could introduce new volatility for gilts and the pound if they trigger leadership changes or heightened political uncertainty.
