The Bank of Japan (BOJ) held off on expanding stimulus on Tuesday, despite pushing back the time frame for hitting its 2 percent inflation target, signaling that it will stand pat unless a severe market shock threatens to derail a fragile recovery.

In a widely expected move, the BOJ maintained the 0.1 percent interest it charges for a portion of excess reserves that financial institutions park with the central bank. At the two-day policy meeting that ended unusually quickly on Tuesday, it also left unchanged its 10-year government bond yield target around zero percent.
