UK Debt Management Office sold 2036 gilt syndication raising £15 bn at 4.9158% yield, highest for 10-year sale since 2008.
Investor demand hit record £148 bn of orders, the largest ever recorded for a UK gilt issuance.
Benchmark 10-year gilt yields topped 5% for first time since 2008, driven by inflation risks and US‑Iran war.
If ceasefire leads to market rally, yields could fall back from current levels.
