TOKYO, March 17 (Reuters) - Japanese government bond

yields were mixed on Monday, ahead of the Bank of Japan's

monetary policy meeting this week amid global uncertainties.

Meanwhile, news that Japan's prime minister had given gifts to

some ruling party members generated concerns about the upcoming

fiscal year's budget.

The 10-year JGB yield dipped 0.5 basis point

to 1.51%, while 10-year JGB futures rose 0.12 yen to

138.26 yen.

The two-year JGB yield was down 3 bps at

0.805% after earlier touching its lowest in a little more than

two week at 0.8%.

The BOJ is expected to hold rates steady at 0.5% when its

two-day policy meeting concludes on Wednesday, putting the focus

on Governor Kazuo Ueda's post-meeting press conference for any

hints about the outlook.

Fears of a global slowdown caused by U.S. President Donald

Trump's tariff policies have been overshadowing Japan's wage and

price data.

Rengo, Japan's largest union umbrella group, announced on Friday

that domestic companies have agreed to raise wages by more than

5% for a second year in a row this year.

But with a preliminary reading of 5.46%, analysts said those

results were within expectations and unlikely to persuade the

BOJ to hike rates early.

The five-year yield declined 2.5 bps to

1.095%.

On the superlong end, the 20-year yield rose

2 bps to 2.285%, while the 30-year yield climbed

to as high as 2.63%, a level last seen in April 2006.

The 40-year JGB yield briefly jumped 7 bps to

a record high of 3%, and was last up 4.5 bps.

"Market participants have been paying a fair amount of

attention to the issue of (Japanese Prime Minister Shigeru)

Ishiba's gift certificates," said Hiroshi Namioka, chief

strategist at T&D Asset Management.

Ishiba apologised on Friday for giving gift certificates to

some ruling party lawmaker.

The issue adds to challenges for Ishiba's minority coalition and

risks delaying passage of next fiscal year's budget.
