Japan's central bank is planning scenarios for an expansion of its already massive economic stimulus program, looking to go beyond its $70 billion-a-month bond-buying operation, according to officials briefed on the process.
Options include major purchases of stock market linked funds or other assets riskier than Japanese government bonds (JGBs), the insiders said.

More radical ideas are also being floated within the central bank and among government officials who deal with the BOJ, including even more aggressive buying up of JGBs - a market already dominated by the central bank under its existing policy.
"There's no sense that further stimulus is imminent," said one of these officials, adding the central bank's inflation target is still a long way off. "There's no harm in thinking about options."
