A gauge of inflation expectations in the bond market rose to the highest level in nine months as oil prices climbed, supporting the Federal Reserve’s plan to raise interest rates twice this year.

The Fed will hold its benchmark unchanged when it meets Tuesday and Wednesday, futures contracts indicate. The session will give policy makers a chance to either ratify or scale back their stance from their last review in March, when they changed their outlook for rate increases this year to two from four. Officials cited weaker global growth while saying they’re monitoring inflation closely.

The difference between yields on five-year notes and same-maturity Treasury Inflation Protected Securities, a gauge of trader expectations for consumer prices over the life of the debt, widened to 1.57 percent at the end of last week. It was the highest level since July, though short of the central bank’s 2 percent target.

“Don’t enter the U.S. bond market at this time,” said Hiroki Shimazu, the senior market economist in Tokyo at SMBC Nikko Securities Inc., a unit of Japan’s second-largest lender. “Inflation pressure will be much higher than the market is pricing.”

Treasuries were little changed, with the benchmark 10-year note yield at 1.88 percent as of 10:42 a.m. in Tokyo, according to Bloomberg Bond Trader data. The price of the 1.625 percent security due in February 2026 was 97 23/32.

Crude oil has risen 66 percent from a 12-year low set in February.
