TOKYO, July 4 (Reuters) - Japanese government bond prices were mostly firmer on Wednesday, supported by risk aversion in the broader financial markets and the Bank of Japan’s regular debt-buying operation.
September 10-year JGB futures gained 0.03 point to 150.95.
The 30-year JGB yield declined half a basis point to 0.840 percent and the 40-year yield was also half a basis point lower, at 0.840 percent.
Activity in the longer-dated maturities was limited as the market braced for Thursday’s 700 billion yen ($6.34 billion) 30-year JGB auction.
The Bank of Japan on Wednesday offered to buy 960 billion yen of one to 10-year JGBs as part of its bond-buying scheme.
Japan’s Nikkei was down 0.4 percent and struggled near a three-month low as lingering global trade concerns continued to limit investor demand for equities. ($1 = 110.4300 yen) (Reporting by the Tokyo markets team Editing by Eric Meijer)
