(Bloomberg) -- The inflation fears that have clobbered short- and intermediate-term U.S. Treasury notes this month could spell trouble for credit markets, according to Bank of America Corp. strategists.

Worries about rising inflation have shrunk the gap between shorter- and longer-term Treasury yields. That kind of yield curve flattening historically hurt investment-grade corporate bond returns, strategists wrote in a report this week that makes the direct opposite call that JPMorgan Chase & Co. made this week.

BofA expects risk premiums to widen substantially for intermediate maturities, and thinks spreads will widen overall. The average spread on the Bloomberg U.S. Corporate Investment Grade Index stood at 85 basis points at Tuesday’s close, near the narrowest level for the year of 80 basis points in June. 

A flatter yield curve gives investors relatively less compensation for buying longer-term bonds like high-grade company debt instead of shorter- or intermediate-term notes, Bank of America said. A less steep curve also tends to increase hedging costs for foreign investors, reducing their demand for U.S. corporate debt, the strategists wrote. Those costs have already started rising for euro- and yen-based investors.

The difference between 5-year and 30-year Treasury yields reached about 85 basis points this week, the narrowest since April 2020. It’s since widened a bit to 96 basis points, but the curve is still substantially flatter than its 157 basis point level in May. 

JPMorgan Chase & Co., meanwhile, expects high-grade bond spreads to “tighten modestly” into the end of the year. 

“Slower earnings and GDP growth from supply disruptions reflect strong demand (a positive) and are not a negative for credit spreads as the demand will be delayed in most cases rather than reduced,” strategists led by Eric Beinstein wrote.
