U.S. 10- to 30-Year Yield Gap Shrinks as Inflation Seen in Check

The difference between 10- and 30-year Treasury yields approached the narrowest level in 17 months on speculation inflation will hold in check as the Federal Reserve reduces its efforts to spur economic growth.

The so-called spread was 1 percentage point. The gap was 97 basis points last week, or 0.97 percentage point, which was the least since Jan. 3, 2012, according to data compiled by Bloomberg. The longest maturities are those most influenced by the outlook for prices in the economy. While U.S. government securities have fallen 2.5 percent this year, Treasury Inflation Protected Securities tumbled 8 percent, Bank of America Merrill Lynch indexes show.

“The economy is not growing fast enough to bring on an inflation acceleration,” said Marc Fovinci, the head of fixed income in Portland, Oregon, at Ferguson Wellman Capital Management Inc., which has $3.5 billion in assets. “I certainly wouldn’t be a holder of TIPS.”

The difference between yields on 10-year notes and same-maturity TIPS, a gauge of trader expectations for consumer prices over the life of the debt, was 2.04 percentage points. The average over the past decade is 2.22 percentage points.
