Wall Street heavyweights Bill Ackman and Larry Fink see inflation remaining higher and expect US Treasury yields to soon hit 5%. Ackman, who is the CEO of Pershing Square Capital, said at CNBC's Delivering Alpha 2023 conference on Thursday that inflation will be persistently higher, while noting that US yields in the 4% range are still low on a historical basis. "I would not be shocked to see 30-year rates well through the 5[%] barrier, and you could see the 10-year approach 5," he said. "And that could happen in the very short-term. Like literally weeks."
