TOKYO, July 17 (Reuters) - Japanese government bond (JGB)

yields were mixed on Friday, with the benchmark 10-year yield

rising for a second straight session while the 20-year yield

edged lower as investors weighed inflation risks and signals for

monetary policy.

Here are a few details:

* The 10-year JGB yield added 0.5 basis point

(bp) to 2.715%. Yields move inversely to bond prices.

* The 20-year yield eased 0.5 bp to 3.585%,

on course for a 16-bp slide this week, the steepest weekly drop

in more than a year following surprisingly strong demand at a

sale of the debt on Tuesday.

* U.S. Treasury and euro-zone yields moved modestly higher

overnight, as steady U.S. economic data, along with higher oil

prices tied to Gulf tensions, reinforced expectations for

further central bank tightening.

* "Crude oil prices continue to fluctuate, and inflation

outlooks and interest rate trends remain highly susceptible to

the influence of the energy market," Takayuki Miyajima, senior

economist at Sony Financial Group, said in a note.

* "The market remains mindful of the uncertainty surrounding

fiscal management and monetary policy, and there is persistent

wariness regarding the risk of rising interest rates, including

in the ultra-long-term segment," he added.

* Domestically, investors continued to monitor the Bank of

Japan's tightening stance. A central bank official signalled on

Thursday that further rate hikes could be needed to address

inflation risks, and household surveys showed a sharp rise in

price expectations.

* The 30-year yield sank 1 bp to 3.820%.

* The two-year yield, the one most sensitive

to BOJ policy rates, was unchanged at 1.425%, while the

five-year yield fell 0.5 bp to 1.945%.
