UK long-term borrowing costs have surged to their highest level since 1998, driven by mounting concerns over rising inflation and political uncertainty ahead of this week's local elections.
Gilt Yields Soar
The yield on 30-year UK government bonds, commonly referred to as gilts, climbed to a 28-year peak on Tuesday afternoon, increasing by 0.14 percentage points to 5.798%. Gilt yields move inversely to bond prices, meaning that as yields rise, the value of the bonds declines. This uptick signals that it has become more expensive for the government to borrow from financial markets.
Impact on Shorter-Term Bonds
The yield on 10-year gilts also rose, gaining 0.15 percentage points to reach 5.122%. However, this remains below the recent highs recorded last month. In contrast, the yield on US 10-year Treasury notes remained flat on Tuesday, though it has been steadily increasing in recent weeks.
Reasons Behind the Rise
The increase in gilt yields is largely attributed to growing expectations that the conflict in Iran will drive higher inflation due to spiking energy costs. This, in turn, is likely to prompt the Bank of England to raise interest rates. City traders currently anticipate at least two interest rate hikes in the coming months, despite the Bank maintaining the current rate at 3.75% last week.
Consequences for Government Finances
The rise in gilt yields means the government will face higher debt interest costs, placing additional strain on the Chancellor's spending capabilities. This development occurs against a backdrop of significant pressure on Prime Minister Sir Keir Starmer in the run-up to the UK local elections.
The pound remained broadly flat against the dollar on Tuesday, trading at 1.353.
