The 10-year Treasury yield BX: TMUBMUSD10Y was above 4.6% on Wednesday, potentially moving closer to reclaiming the 5% mark, a level last seen in 2007. But the move higher from roughly 3.4% in May for the U.S. economy’s benchmark rate has been particularly troubling.

Szczurowski attributed part of the massive selloff to the Federal Reserve signaling last week that rates may stay higher for longer than previously anticipated, which eventually would pinch corporate profitability and potentially spur more defaults.

“People are starting to come around to — which is not my view — of a higher for longer stance on rates,” Szczurowski said.

“It also has kind of been a one-way street higher in the longer end of the Treasury market,” he said, since the Bank of Japan’s decision in July to loosen up its policy of yield-curve control could be spurring Japanese investors, the top group of foreign holders of U.S. debt, to sell. Bond yields and price move in the opposite direction.

The current backdrop also differs from a year ago in that a “buyers’ strike” from institutional investors appears to be forming, he said, whereas investors last September were “buying the dip” as stress in the U.K. pension system rattled financial markets.

Still, Szczurowski said a soft landing for the economy would be tough for the U.S. to achieve, if rates stay high, the labor market stays strong and inflation ends up resistant to falling all the way back to the Fed’s 2% annual target.

“It’s like doing a plank for 10 seconds,” he said of the economy navigating the Fed’s current 5.25% -5.5% policy rate range. “You can do it, but if you try to do a plank for 10 minutes there’s a lot more stress on your body. It will have an impact.”

To that end, he also expects the Fed to cut rates quicker than its updated “dot plot,” a chart of the potential path of rates, suggests.

His other advice for investors? It could take week or two, but he thinks current yields on 10-year and 30-year Treasury notes could spur more money-managers, pension funds and insurance companies back to the market.

Stocks closed mostly higher Wednesday, with the Dow DJIA off about 0.2%, the S&P 500 index SPX less than 0.1% higher and the Nasdaq Composite Index COMP up 0.2%, according to FactSet data.
