TOKYO, Nov 27 (Reuters) - Japanese government bond (JGB)

yields rose across the curve on Wednesday, as an auction of the

40-year note saw weak demand and expectations for reduced

issuance of those notes within this year retreated.

The 40-year JGB yield rose 5 basis points to

2.655%.

"The weak auction outcome prompted inventors to sell bonds

across the curve," said Katsutoshi Inadome, a senior strategist

at Sumitomo Mitsui Trust Asset Management.

The benchmark 10-year yield rose 1 bp to

1.07%. The 20-year yield rose 2.5 bps to 1.89%

and the 30-year yield rose 2.5 bps to 2.305%.

The expectations for the cut in sales of the 40-year bonds

weakened after a meeting of JGB primary dealers held on Tuesday.

The Ministry of Finance, which is working on plans for JGB

issuance for the next fiscal year which starts on April 1, 2025,

acknowledged the demand from the market for sales of less

40-year bonds, according to a summary of the meeting.

However, the ministry did not indicate that it would trim

the 40-year bond sales before the next fiscal year starts.

"That was a disappointment for those who had expected the

cut in the amounts at an early stage," Inadome said.

Yields on bonds with shorter maturities also rose, with the

two-year JGB yield inching up 0.5 bp to 0.59%.

The five-year yield rose 1 bp to 0.74%.
