Pound Sterling Weakened by Looming Budget Uncertainty

The British pound is showing signs of strain ahead of the upcoming Budget, according to analysts at Barclays. The bank's weekly strategy note suggests that rising global borrowing costs and uncertainty surrounding the Budget are contributing to this weakness.

The cost of UK debt has risen to its highest level since 2007, reducing Chancellor John Healey's room for maneuver in terms of spending and tax plans. Matthew Ryan, Head of Market Strategy at Ebury, warns that the Autumn Budget will likely involve higher ancillary tax rates and increased debt issuance.

The pound-to-euro rate has fallen to a low of 1.1622, while the pound-to-dollar conversion has dipped to 1.3474. Barclays' analysts believe that sterling is in a short-term pullback within a broader uptrend, but warn that the selloff could become more pronounced if bond yields continue to rise.

Rising oil and gas prices are also playing a significant role in the pound's weakness, as global yields have firmed up due to higher oil prices and US Treasury yields. This is creating a challenging backdrop for Burnham's government and poses risks for the pound.
