In Asia, the yen's plunge to its lowest level in almost three years against the dollar and euro dominated market sentiments. The recent stimulus optimism, that had pushed the local currency lower by about 15 percent against the dollar in about three months, was further boosted after the Bank of Japan governor Masaaki Shirakawa announced that he will step down from his post earlier than expected.
Shirakawa's resistance to aggressive monetary stimulus measures that could help to boost growth had spiked concerns on Japan's economic outlook. The country's newly elected government supports unlimited aid measures to rev up activities and had demanded that the central bank respond to the economic weakness with action.
Analysts suggest that after Shirakawa, the government may opt for someone who is more accommodative to the government's demands. This has given rise to concerns on the central bank's independence, but has helped to weigh the yen lower and push stock markets higher.
"After the new BOJ leadership announcement scheduled for mid to late February, Shirakawa is expected to be a kind of lame duck and thus, his decision to depart early is not so surprising," said Yujiro Goto, economist at Nomura Research.
"We have expected the new BOJ leader to embark on more aggressive easing and we think the timing of the easing is earlier now, which is marginally positive for USD/JPY".
