TOKYO, June 27 (Reuters) - Japanese government bond prices were flat across the board on Wednesday, with support from risk aversion in broader markets neutralised by lukewarm demand for fresh supply in the longer-dated maturities.
The five-year and 10-year JGB yields were unchanged at minus 0.115 percent and 0.030 percent, respectively. The 40-year yield was also flat, at 0.865 percent.
Tuesday’s 1 trillion yen ($9.10 billion) 20-year JGB auction saw weak investor demand due to their relatively low yields.
Japan’s Nikkei was down for the second session on Wednesday as lingering concerns over a row between the United States and its trading partners curbed risk appetite. ($1 = 109.9500 yen) (Reporting by the Tokyo markets team; Editing by Sunil Nair)
