LONDON — The yield on Britain’s benchmark ten-year government bond reached 5.295% on 10 September, its highest level since August 2007.

The increase came during a wider global bond-market sell-off as Brent crude rose above $100 per barrel. Higher energy costs can sustain inflation and reduce expectations of rapid interest-rate cuts.

Yields on shorter-term British debt also climbed. The two-year gilt reached 4.742%, while the five-year yield rose to 4.828%, according to market figures reported during the trading session.

A £5 billion auction of government bonds maturing in May 2030 attracted bids of about £16.2 billion. Demand remained strong, but buyers required the highest average yield for that maturity since 2023.

Rising yields increase the government’s cost of borrowing and can feed into mortgage and business-loan rates. They may also complicate fiscal planning by raising the cost of servicing the national debt.

Investors will now watch oil prices, inflation indicators and Bank of England communication. A lasting energy shock would make it harder to balance price stability with economic growth.
