Are inflation and debt worries pushing long-term yields to decades-highs?
Core argument: The 30-year US Treasury yield rose as much as 0.09 percentage points to 5.73%, its highest level since 2002, before easing to 5.66% following a strong 10-year Treasury auction.
A sell-off in US government bonds eased after an auction of 10-year Treasuries drew strong demand in a sign that investors were seeking to lock in the highest yields since the turn of the millennium. US 10-year Treasury yields, a benchmark for borrowing costs in the world’s biggest economy, climbed as high as 5.36% in volatile trading early on Wednesday. But yields fell back sharply after a $39bn auction went smoothly, with the 10-year recently trading at 5.29%. France’s 10-year borrowing costs rose to 4.87%, heading back towards the post-2002 high reached this month, amid persistent worries that the Eurozone’s second-biggest economy was heading for a debt reckoning.
