TOKYO, Oct 23 (Reuters) - Japanese government bond prices edged higher on Tuesday as Asian share prices fell on a cocktail of negative drivers from Saudi Arabia’s diplomatic isolation to worries about trade wars, hitting sentiment across the region.
Ten-year JGB futures advanced 0.10 point to 150.29, while the yield on the current 10-year cash JGBs fell 0.5 basis point to 0.145 percent.
The 20-year JGB yield shed 0.1 basis point to 0.680 percent, while the 40-year JGB yield dipped half a basis point to 1.080 percent.
The 30-year JGB yield was flat at 0.915 percent.
The five-year JGB yield and two-year JGB yield were untraded.
Traders said many market participants were on the sidelines ahead of a meeting the Bank of Japan holds later on Tuesday with market players about its market operations.
There is speculation that the BOJ could use the meeting to pave the way for slight tweaks in its operation to make bond trading more active. (Reporting by Tokyo Markets team; Editing by Subhranshu Sahu)
