STORY LINK GBP/USD Forecast: Pound Sterling Movement "Limited" as All Eyes on Iran

The Pound to US Dollar (GBP/USD) exchange rate moved within a tight range on Tuesday, as investors held back ahead of a key deadline tied to US policy on Iran.

At the time of writing, GBP/USD was hovering around $1.3209, little changed from where it began the session.

The US Dollar (USD) lacked clear direction, with traders reluctant to take strong positions ahead of a looming decision from Washington.

US President Donald Trump has issued Tehran with a deadline to agree to terms deemed acceptable by the US, warning that failure to comply could result in significant military action targeting critical infrastructure.

Iran has responded with its own warnings, signalling that any such move would provoke retaliation across the region, including potential strikes on key facilities in the Gulf.

This standoff has left markets on edge, with investors concerned that any escalation could further disrupt shipping through the Strait of Hormuz and intensify the global energy shock.

At the same time, softer US data added to the cautious tone, with February’s durable goods orders falling by more than anticipated.

The Pound (GBP) also struggled to gain traction following the release of the UK’s latest services PMI figures.

Final data for March showed activity in the sector slowed more sharply than first thought, with the index slipping from 53.9 to 50.5, only just remaining in expansion territory.

The reading highlights a cooling in one of the UK’s most important growth drivers and reinforces concerns about the broader economic outlook.

For the Bank of England, the figures complicate the policy backdrop, as officials must weigh persistent inflation risks against signs that economic momentum is already beginning to fade.

Short-Term GBP/USD Forecast: Geopolitics in Focus

Movements in the Pound to US Dollar exchange rate are likely to remain driven by developments in the Middle East.

If the US opts to delay or soften its stance, easing tensions could lift risk appetite and weigh on the US Dollar, potentially allowing GBP/USD to move higher.

Conversely, any follow-through on the threatened action could trigger a flight to safety, boosting demand for the US Dollar and pulling the pair lower.
