Japanese government bonds gained on Friday, recovering from an earlier drop after the Bank of Japan cut interest rates for the first time in seven years, joining a global wave of monetary easing to contain a world-wide financial crisis.
The Nikkei average's 5 percent slide also underpinned JGBs. The bond market moved nervously prior to the BoJ's monetary policy decision, rising early in response to weaker Tokyo shares but tumbling when the central bank meeting dragged on longer than usual.
But JGBs trimmed losses after the BoJ announced that it would cut interest rates by 20 basis points to 0.30 percent. The BOJ policy board's vote was split 4-4, with Governor Masaaki Shirakawa casting the deciding vote.
December 10-year futures rose 0.07 to 137.98, pulling back from a low of 137.07. The benchmark 10-year yield dipped 1.5 basis points to 1.470 percent after hitting 1.520 percent.
"The market had expected a 25 basis point cut, but it still showed a positive reaction to the easing decision by the BoJ," said Satoshi Yamada, a senior strategist at Nikko Citigroup.
The BoJ also said it would cut its Lombard rate to 0.50 percent from 0.75 percent and would start paying interest on excess reserves of commercial banks held at the central bank until the March reserves period. "It is noteworthy that the policy board's vote was split at 4-4, which gives the impression that dissent towards a cut was strong," said Yamada at Nikko Citigroup.
Market watchers said that after Friday's split vote the central bank could have an increasingly difficult time making further policy decisions. "Monetary policy for central banks points toward easing as the global economy and financial systems are in a slump," said Jun Ishii, chief fixed-income strategist at Mitsubishi UFJ Securities.
