TOKYO, July 11 (Reuters) - Long-dated Japanese government bond prices dipped on Wednesday as caution towards an upcoming 20-year debt auction offset potential support from a slide in equities.
The 20-year JGB yield rose half a basis point to 0.48 percent ahead of Thursday’s 1 trillion yen ($9 billion) 20-year JGB auction.
The 30-year and 40-year JGB yields each rose half a basis point to 0.69 percent and 0.810 percent , respectively.
The 10-year JGB yield was up half a basis point at 0.040 percent, while the five-year yield was flat at minus 0.110 percent.
The BOJ on Wednesday offered to buy 960 billion yen of one- to 10-year JGBs as part of its bond-buying programme, helping limit losses in the overall market.
Equities tumbled after the United States’ decision to impose tariffs on an additional $200 billion worth of Chinese goods made investors risk averse.
