Treasury inflation protected securities are underperforming other government bond exchange traded funds as inflation inched up at its slowest pace in five months.

TIP, which track government bonds whose face value rises with inflation, has an effective duration of 7.54 years and a 2.11% 30-day SEC yield. IEF shows an effective duration of 7.84 years and a 2.9% 30-day SEC yield.

The consumer price index rose 0.1% in July after increasing 0.3% over June, reports Victoria Stilwell for Bloomberg. The so-called core measure, which excludes food and fuel prices, inched up a lower-than-expected 0.1%.

Observers argue that consumer prices remain relatively unchanged due to the sluggish global demand.

Additionally, the low inflationary pressure will give the Federal Reserve more room to keep rates at near-zero levels, bolstering the appeal for fixed-income assets. Rising inflation lowers the real rate of return on fixed-income yields.

“Some of the inflation concerns that you were hearing back in June will probably ease off a little bit,” Michael Feroli, chief U.S. economist at JPMorgan Chase & Co., said in the article. “It takes some pressure off the Fed to speed up rate normalization. There had been a lot of rhetoric about the Fed being behind the curve on inflation, and this probably takes some wind out of that.”
