Incoming prime minister Andy Burnham enters office during a favorable shift in the bond market. After a period of high volatility, 10-year gilt yields have fallen to 4.7 per cent. This decline provides a reprieve for public finances following a peak of 5.2 per cent last month.

Market instability was driven more by global shocks than local politics. A war in Iran spiked oil prices above $100 a barrel and reignited inflation, hitting the UK's relatively small and sensitive bond market hard. Investors are now moving on as oil prices collapse toward $70 a barrel.

Stability also stems from the US, where Fed chair Kevin Warsh signaled a willingness to fight inflation despite political pressure. This restores institutional credibility and helps lower global yields. Burnham must now avoid excessive borrowing to maintain this momentum and prevent yields from climbing again.

Economic growth remains the only permanent solution to the UK's debt burden. While global forces currently favor the new administration, investors remain wary of fiscal spending. The government's ability to maintain credibility will determine if these lower borrowing costs persist.
