TOKYO, March 7 (Reuters) - Japanese government bond prices gained on Thursday, and their yields pulled back from recent highs as a 30-year debt auction attracted ample investor demand and shored up the market.
JGBs were also supported as Japanese stocks slipped to a one-week low and enhanced the allure of safe-haven bonds.
March 10-year JGB futures edged up 0.02 point to 152.54.
The 20-year JGB yield dipped half a basis point to 0.435 percent. The yield had risen to a five-week peak of 0.450 percent earlier in the week.
The bid-to-cover ratio, a gauge of demand, at Thursday’s 700 billion yen ($6.27 billion) 30-year JGB auction was 4.56, compared with 4.19, the average from the past 10 sales.
The new 30-year JGBs were seen to have drawn bids from investors looking to replenish their inventories ahead of the March 31 fiscal year-end.
The Nikkei was down 0.8 percent, with chip-related stocks hit by a decline in their U.S. counterparts.
