TOKYO  - Japanese government bond yields pared earlier advances on Monday following a report that the Ministry of Finance is considering buying back some super-long bonds it issued at low interest rates.

Such a move would come on top of an expected government plan to trim issuance of the longest-dated debt in the wake of sharp rises in yields last month, Reuters reported citing two sources with direct knowledge of the plan.

The 10-year JGB yield ended the day flat at 1.455% and briefly dipped to 1.450% following the report. It had earlier risen as high as 1.475%.

JGB yields were initially pulled higher by an advance for U.S. Treasury yields after resilient labour market data on Friday saw traders pare back bets for a near-term Federal Reserve interest rate cut.

Traders now see 63% odds of a Fed cut by September, down from 74% before the monthly payrolls report.

The 30-year JGB yield was 1.5 bps higher at 2.89%, but down from as high as 2.92% earlier on Monday.

The five-year yield ended 1 bp higher at 1.02%, paring a 2 bps advance.

The 20-year and two-year hadn't changed hands following the Reuters report, and remained 3 bps higher at 2.36% and 1.5 bps higher at 0.775%, respectively.

Super-long JGB yields pushed to a quarter-century high of 2.600% for 20-year JGBs and a record 3.185% for 30-year JGBs last month, as investors shied away from the longest-dated securities amid growing angst about developed-nation deficits, including in Japan. The rise was later exacerbated by poor results at super-long JGB auctions. However, the finance ministry's pledge to examine reduced issuance of super-long debt marked a turning point for the JGB market.

Now, in the event of a poor JGB auction, investors still buy the bonds in the belief that the finance ministry will pare issuance even more, said Yunosuke Ikeda, chief macro strategist at Nomura.

"A kind of built-in stabilization system is at work," Ikeda said. "In that sense, we can say The worst period is over."
