JGB futures hit 1-month low as Nikkei gains

TOKYO, Feb 4 (Reuters) - Japanese government bond futures fell to a one-month low on Monday as Tokyo shares climbed, spurring selling in safe-haven government debt.

Caution before an auction of 10-year JGBs on Tuesday also weighed on bond prices, traders said.

March 10-year futures 2JGBv1 fell as low as 137.17, down 0.69 point on the day and hitting the contract's lowest since early January.

The Nikkei stock average was up 2.8 percent .N225. (Reporting by Chikako Mogi)
