TOKYO -- The Bank of Japan may have been saddled with as much as 600 billion yen ($4.4 billion) in unrealized losses on its Japanese government bond holdings earlier this month, as a widening gap between domestic and overseas monetary policy pushed yields higher and prices lower.
At Nikkei's request, Nomura Securities, Mizuho Securities and Mitsubishi UFJ Morgan Stanley Securities estimated the state of the central bank's JGB portfolio on June 15, before its most recent policy board meeting, where it decided to maintain its ultraloose policy.
