Treasuries-US bonds trim gains as prospects for Iran deal fade; inflation data looms
TLT•CPI and PPI data in focus
Investors are also awaiting key inflation data — the U.S. Consumer Price Index — due on Wednesday, which could determine the path of interest rates.
"If you know where oil prices and CPI are going, you can tell where Treasury yields are going as well," said Stan Shipley, fixed income strategist at Evercore ISI in New York.
He noted, though, that long-term break-even inflation is well contained, which means the market thinks the Federal Reserve will get prices under control.
"Maybe we have some problems in the short term here over the next year, but the long term over the next 10 years is fine. So unless inflation blows out again, I don't think the 10-year is going to go through this 4.70% hurdle."
Consumer prices are expected to edge up 0.1% in July after falling 0.4% in June, according to a Reuters poll. Annual CPI inflation is forecast to slow to 3.4% from 3.5% a month earlier. Core CPI, which excludes volatile food and energy prices, is also projected to rise 0.2% on the month, from an unchanged reading in June, with annual core inflation seen easing to 2.5% from 2.6% the previous month.
