UK Bond Markets on Alert

Andy Burnham’s potential path to Parliament has added a political risk premium to UK bonds in a major blow to the government’s cost to borrow. The yield on 10-year gilts rose 10 basis points at open, whilst on the 30-year, the yield was up 12 basis points. 

Comparatively, across Europe, all bond yields have continued to rise amid the war in West Asia, but have done so at a reduced rate in the UK. Belgium and France’s respective 10-year yields were up five basis points.

Deutsche Bank's Jim Reid says, "The last 24 hours have brought many headlines, but the biggest is that Greater Manchester's Mayor Andy Burnham is seeking to return to Parliament. He now has a path to do so, because an MP in the region announced he'd be standing down to trigger a by-election, which Burnham has said he'll try to stand in. So if he's successful and becomes an MP, that would mean he could challenge for the party leadership to become Prime Minister."
