Bank of Japan (BoJ) is meeting for a two-day policy review and speculations are on that the central bank will raise inflation targets and boost its asset purchase plans to aid Japan's lagging economy. The country's newly elected government, which came to power with stimulus promises, has recommended the inflation target to be two percent.
Stimulus optimism had weighed the yen lower against the dollar in the recent weeks, encouraging exporters' stocks in Tokyo. But the greenback weakened modestly against the Japanese currency during the day, trading at ¥89.54, down from ¥90.25 mark touched earlier.
If BoJ relents to government pressure and takes up aggressive monetary easing measures, it will be a major shift in its policy stand. The central bank has, for long, limited its fiscal measures to periodically boosting its asset purchase programme.
Though a strong stimulus stand is expected to cheer the financial markets, analysts warn that any such measure should be backed by effective fiscal reforms. Concerns are also high that an extremely weak yen could increase import costs and further hurt the economy.
German December Producer Price Index will be released during the day and analysts expect the gauge to have picked up to 1.7 percent in the month from 1.4 in the previous.
