UK 10Y Bond Yield Hits 19-year High

UK 10-year gilt yields climbed to 5.5%, their highest since July 2007, while 30-year yields reached 6% for the first time since 1998 as a renewed global bond selloff gathered pace. The 10-year yield rose more than 20 basis points in September, as higher energy costs fueled inflation concerns and stronger-than-expected economic growth strengthened the case for higher-for-longer interest rates. Several Bank of England policymakers, including Governor Andrew Bailey and MPC members who voted to hold rates last month, have signaled growing openness to a rate hike as rising energy prices increase the risk of inflation remaining above target. Markets expect the Bank of England to begin tightening monetary policy as early as November, with LSEG data showing investors pricing in four rate hikes by July 2027. Higher borrowing costs come at a challenging time for the government, which is seeking to ease cost-of-living pressures ahead of the October 28 budget.

UK 10-year gilt yields hovered below 5.4% at the end of September, slightly below a 19-year high reached earlier in the month, as markets became more cautious about further central bank rate hikes. Despite this, gilts endured a sharp selloff over the month, with yields rising 23 bps. Higher energy prices stoked inflation concerns, while expectations that the AI boom could support economic growth strengthened the case for higher-for-longer interest rates. Market sentiment improved on Wednesday as central bankers pushed back against expectations of rapid and sustained tightening. Bank of England policymaker Alan Taylor played down the need for rate hikes to address the UK’s energy crunch, contrasting with more hawkish comments earlier in the month from other MPC members, including Governor Andrew Bailey. In the US, Fed's John Williams likewise said there was time to assess incoming data before raising rates again. Meanwhile, upward revised figures showed UK GDP grew 0.5% in Q2.

UK 10-year gilt yields remained close to 19-year highs, hovering below 5.4%, as persistent inflation concerns and a more hawkish Bank of England stance continued to weigh on bonds. The government also paid its highest 10-year borrowing cost since 1999, selling £4.25 billion of 4.875% bonds maturing in July 2036 at an average yield of 5.383%, as investors demanded higher premiums amid inflation risks and expectations of increased government spending in next month’s budget. On the monetary policy front, BoE Deputy Governor Dave Ramsden said on Monday he would support rate hikes if inflationary pressures persist, echoing recent warnings from Governor Andrew Bailey. The MPC recently voted to hold rates at 3.75%, while warning inflation could peak around 4%. Markets are now pricing in a near 80% probability of a 25bp rate hike in November, with roughly four increases priced in by the middle of next year.
