GBP Under Pressure as UK Political Risk Rises While Middle East Ceasefire Lifts Market Sentiment

Key Highlight

• A temporary ceasefire between Israel and Lebanon has eased immediate geopolitical tensions, supporting broader US-Iran diplomatic progress and improving risk sentiment.

• Political uncertainty in the UK has intensified, adding pressure to sterling amid renewed scrutiny surrounding Prime Minister Starmer and recent security vetting concerns.

• Diverging central bank outlooks remain a key driver in FX markets, with the ECB maintaining a firmer stance compared to a more cautious Bank of England.

Market Recap

The US dollar regained ground, ending a prolonged losing streak as rising UK political concerns weighed on sterling. This overshadowed stronger-than-expected UK economic data, where GDP expanded by 0.5% in February—well above expectations. Despite this, GBP weakened modestly against the dollar and held broadly steady versus the euro, as markets focused on forward-looking risks rather than backward-looking data.

Comments from the Bank of England reinforced this cautious sentiment, with policymakers indicating no urgency to tighten monetary policy further. At the same time, political developments in the UK unsettled markets. Reports surrounding security clearance issues linked to a senior diplomatic appointment triggered renewed calls for leadership change, increasing uncertainty around the fiscal outlook and policy direction.

In the US, economic data presented a mixed picture. Labour market indicators showed resilience, while regional manufacturing activity improved notably. However, an unexpected decline in industrial production tempered the overall outlook. In Europe, inflation was revised slightly higher, with policymakers signalling that geopolitical developments could have lasting implications for price pressures.

Market Update

Geopolitical developments remain front of mind for markets. Optimism has increased following signals that the US and Iran may move closer to a more durable agreement, with further discussions expected in the near term. However, market reaction has been measured, with investors showing reluctance to fully price in a swift resolution given ongoing uncertainty around the timeline.

In the UK, sterling faces a challenging backdrop. Domestic political tensions are building at a sensitive time, with upcoming elections and growing speculation over leadership stability. This is contributing to a higher political risk premium, which could continue to weigh on the currency, particularly if uncertainty escalates further. Longer-term UK bond yields are also beginning to reflect these fiscal concerns, while short-term expectations remain anchored by a cautious central bank stance.

Meanwhile, the euro continues to find support from a relatively more hawkish policy outlook. With European policymakers leaving the door open to further tightening, the contrast with the Bank of England’s more measured approach is becoming increasingly evident—reinforcing downside pressure on GBP relative to EUR.
