BOND EXPERT WARNS OF $110 BILLION SELLING SHOCK IF TREASURY YIELDS HIT 6% Veteran bond strategist Harley Bassman warns of a “nightmare scenario” in U.S. Treasuries. If the 20-year Treasury yield rises above 6%, futures-related hedging could trigger selling pressure equivalent to $110 billion in bond issuance. The 20-year yield currently stands near 5.6%. Bassman says negative convexity risks have reached levels not seen since 2007, potentially amplifying the Treasury selloff.(彭博社)
