The UK government sold 10-year bonds on Tuesday at the highest yield since the global financial crisis.

The 2036 gilt syndication raised a record £15 billion and attracted £148 billion of investor orders, the most ever, according to data compiled by Bloomberg.

The UK debt securities will provide investors with a yield of 4.9158%, the UK Debt Management Office (DMO) said.

That’s the highest for any UK 10-year bond sale since 2008.

Reuters said the syndication represented ⁠the biggest supply at ​a single event since the UK Debt Management Office began operations in 1998, but also the costliest 10-year borrowing since an auction in July 2008.

The ​DMO sold ‌the 2036 gilt at a premium of 8.5 basis points over the 10-year benchmark gilt that launched with a then-record volume of £14 billion in September.

UK debt securities have fared worse ‌than other advanced economy debt since the beginning of the Iran war in late ​February.
