Japanese government bond yields rose on Thursday as investors showed scant response to a positive outcome of a liquidity auction. The 10-year JGB yield rose one basis point to 0.065% and the 20-year JGB yield also climbed one basis point to 0.460%. Earlier in the day, the liquidity auction received bids worth 3.17 times the amount available, which was lower than a bid-cover ratio of 3.94 times at the previous auction. Still, a market participant said the demand was rather solid as investors scooped up maturities that were out of their portfolio. The 30-year JGB yield rose 1.5 basis points to 0.680% and the 40-year JGB yield rose one basis point to 0.715%. The two- and five-year bonds were not traded and the two-year JGB yield remained at minus 0.120% and the five-year yield at minus 0.095% as both maturities did not trade. Benchmark 10-year JGB futures fell 0.13 point to 151.79, with a trading volume of 17,230 lots. (Reporting by Tokyo markets team)
