NEW YORK (Reuters) - U.S. Treasury prices moved little Thursday after a mixed bag of economic news hinted that inflation remains tame, but the manufacturing sector may be heating up.

The benchmark 10-year note fell 1/32 to 102-1/32 to yield 4.48 percent, unchanged from Wednesday, and the 30-year bond added 1/16 of a point to 102-7/32 to yield 5.21 percent, also unchanged from late Wednesday.

The two-year note dropped 1/16 of a point to 100-7/32 to yield 2.60 percent, and the five-year note dipped 1/32 to 99-23/32 to yield 3.68 percent.

The Labor Department said its producer price index (PPI), a measure of wholesale prices, fell 0.3 percent after rising 0.8 percent in May. The so-called core PPI, which excludes often-volatile food and energy prices, rose 0.2 percent after rising 0.3 percent in May.

Economists, on average, expected PPI to rise 0.2 percent and core PPI to rise 0.2 percent, according to Briefing.com.

In the manufacturing sector, the Philadelphia Fed's July business activity index climbed to 36.1 in July, when analysts had looked for a pullback to 25.0 from June's 28.9.

The report is considered important by analysts since it is one of the first readings on the month and supports those calling for the economy to revive this quarter after a slowdown last quarter.

"It suggests that the industrial production setback reported for June is unlikely to last and that production geared up the very next month," Chris Rupkey, senior financial economist at Bank of Tokyo Mitsubishi, told Reuters.

Meanwhile, jobless claims jumped by 40,000 to 349,000, but expected seasonal shutdowns at auto plants played a large role in that increase.

In the currency market, the dollar inched higher against the euro and the yen. The euro bought $1.2331, down from $1.2392 late Wednesday, and the dollar bought ¥109.81, up from late Wednesday's ¥109.15.
