0534 GMT - It is not impossible to get through the coming months without another significant move higher in long-end yields, but the balance of probabilities suggests there is at least one more leg of long-end weakness still to play out, ING's Padhraic Garvey and Michiel Tukker say in a note. "In an extreme scenario, this could take U.S. 10-year yields into the 5.25% to 5.5% range," say Garvey, regional head of research for the Americas and Tukker, senior U.K. and eurozone rates strategist. The U.S. 10-year took note of the better-than-expected U.S. purchasing managers data, and shot back above 5%, even breaching 5.1%, they say. The 10-year Treasury yield hit 5.14% on Wednesday, an intraday level last seen in July 2007. It last trades at 5.115%, up 0.2 basis points, according to Tradeweb.
