Super-long Japanese government bond (JGB) yields jumped back on Thursday, after a 30-year bond auction received weak investor demand.

TOKYO, June 13 (Reuters) - Super-long Japanese government bond (JGB) yields jumped back on Thursday, after a 30-year bond auction received weak investor demand.

The bid-to-cover ratio, a gauge of demand, at Thursday's 700 billion yen ($6.5 billion) 30-year JGB sale fell to 3.47 from 4.65 at the previous auction in May. The auction's tail, or gap between the lowest and accepted prices, was 0.87, the widest in the past 5 years.

The results undershot market expectations because many investors had very high expectations after last month's strong auction results and recent rally in global bond markets.

Market analysts attributed the disappointing auction results to some advance buying.

In the super-long zone, the 30-year cash JGB yield JP30YTN=JBTC jumped 2.5 basis points to 0.365%, while the 40-year yield JP40YTN=JBTC climbed 2 basis points to 0.395% and the 20-year yield JP20YTN=JBTC advanced one basis point to 0.255%.

September 10-year JGB futures 2JGBU9, which took over the benchmark status from June contract on Wednesday, ended the session unchanged at 153.44, with a trading volume of 32,136 lots, while the 10-year cash JGB yield JP10YTN=JBTC was also flat at minus 0.130%.
