London, UK – The United Kingdom's long-term borrowing costs have climbed to their highest level since early 1998, driven by a global bond market sell-off. On Tuesday, the yield on 30-year UK government bonds, known as gilts, reached 5.89%, according to reports from The Guardian [1]. This increase in yield, which effectively represents the interest rate the government pays to borrow, marks a significant rise. The 30-year gilt yield jumped by 9 basis points to 5.88%, a level not seen since March 1998 [2].
