TOKYO, Aug 22 (Reuters) - Prices of longer-dated Japanese government bonds (JGBs) dipped on Thursday, tracking an overnight retreat by their U.S. counterparts, although the market was confined to a narrow range ahead of a central bankers’ meet at Jackson Hole this weekend.
The 30-year JGB yield rose half a basis point to 0.185% and the 20-year yield nudged up half a basis point to 0.085%.
An auction designed to provide the market with extra liquidity attracted ample demand on Thursday.
The bid-to-cover ratio, a gauge of demand, at the so-called liquidity enhancing auction rose to 2.87 from 2.77 at the previous sale.
The finance ministry offered 600 billion yen ($5.64 billion)of JGBs with remaining maturities of five to 15.5 years at Thursday’s auction.
