UK Borrowing Costs Hit 6% Amid Global Bond Market Sell-Off
Gilt yields reach highest level since 1998 as investors demand higher returns to lend to the British government.
Britain's borrowing costs have surged past 6%, making it the first G7 economy to reach this threshold since the eurozone crisis. The yield on UK 30-year government bonds, known as gilts, climbed to 6.03% on Thursday, a level not seen since 1998. This marks a significant increase from September 2012, when similar 30-year debt was priced at just over 6% while UK debt was at half that rate.
The rise in gilt yields reflects a broader global bond market rout, which also impacted stock markets. The FTSE 100 index fell by as much as 2% in early trading on Thursday before closing 1.7% lower.
Analysts attribute the market volatility to several factors. Persistent geopolitical tensions, including the ongoing conflict in Iran initiated by former President Donald Trump, have driven up oil and gas prices, fueling inflation fears and concerns over government debt. Hopes for a lasting resolution to the conflict have faded in recent weeks, intensifying these anxieties.
In the UK, investor concerns are also heightened by the approaching Budget and the Labour party's approach to the rising benefits bill. Economists estimate that Chancellor John Healey's fiscal headroom, a buffer against meeting borrowing and debt targets, has shrunk from £24 billion to approximately £8 billion since March.
Susannah Streeter, chief investment strategist at Wealth Club, noted that the bond market is adding pressure ahead of the UK Budget. "With debt already high and interest payments eating up a hefty chunk of public finances, sustained yields at these levels could further squeeze the Chancellor’s wiggle room when he sets out his spending plans," she said.
The increase in gilt yields has wider implications for borrowers. Higher borrowing costs for the government typically translate to increased rates for mortgages and other loans. Data from L&C Mortgages indicates that the average two-year fixed mortgage rate has already risen from 4.68% to 5.11% in the past month, adding approximately £600 annually to a typical £200,000 repayment mortgage.
"The ongoing turmoil in the global markets is likely to spell more bad news for mortgage borrowers," commented David Hollingworth, associate director at L&C Mortgages.
Dan Coatsworth, head of markets at AJ Bell, explained the concept of "bond vigilantes," where investors sell bonds to protest perceived fiscal irresponsibility, pushing down prices and raising yields. This, he noted, serves as a powerful incentive for governments to restore market confidence.
