SYDNEY, Oct 16 (Reuters) - Japanese government bond prices mostly edged lower on Wednesday, in line with retreating global bond prices on a report that negotiators were close to a deal to avoid a disorderly British exit from the European Union.
However, lingering uncertainty surrounding U.S.-China trade talks and Brexit have kept many investors wary about the global economic outlook, underpinning demand for long-dated debt.
Benchmark 10-year JGB futures dipped 0.07 points to 154.40 in early afternoon trade, while the yield on the 10-year cash JGBs rose 1 basis point to minus 0.165%.
The two-year JGB cash yield rose 1 basis point to minus 0.275%, its highest in nearly a month, while the five-year yield also gained 1 basis point to minus 0.290%.
The longest end of the yield curve fared better, enjoying steady demand from investors as the only source of positive yield in the market, with the 40-year JGB yield falling 0.5 basis point to 0.425%.
