SINGAPORE, Jan 14 (Reuters) - The yen hit a 2-1/2-year low versus the dollar on Monday after Japanese Prime Minister Shinzo Abe urged the Bank of Japan to set a medium-term inflation target, in a reiteration of his calls for forceful monetary stimulus.
In comments that came ahead of the BOJ’s policy meeting on Jan. 21-22, Abe said on Sunday that the BOJ must set a 2 percent inflation target and make it a medium-term goal rather than a long-term objective.
Abe also said on Japanese public broadcaster NHK that he will meet with monetary policy experts on Tuesday to seek views on who would be suitable as next BOJ governor.
Abe’s government has the power to nominate a successor to BOJ Governor Masaaki Shirakawa when his term expires in April, although the nomination needs approval by both houses of parliament.
While some market players attributed the yen’s drop on Monday to the breach of a dollar/yen option barrier, others said the new Japanese prime minister’s latest call for aggressive monetary easing helped drag the yen lower.
The dollar rose to as high as 89.67 yen on trading platform EBS as of 0403 GMT, the greenback’s highest level versus the Japanese currency since June 2010.
“The confirmation that there’s going to be a push for a new (BOJ) governor, that new governor is going to have a mandate of 2 percent inflation, that plus the fiscal stimulus is a major negative for the yen,” said Callum Henderson, global head of FX research for Standard Chartered Bank in Singapore.
“Good news for Japanese assets, certainly in terms of the stock market, but not necessarily good news for the currency,” he added.
Japan last week approved a $117 bln stimulus package, the biggest spending boost since the financial crisis, to try and support the economy.
The dollar last changed hands at 89.64 yen, up 0.5 percent from late U.S. trade on Friday. Market players said the dollar breached an options barrier at 89.50 yen, and there was talk of another barrier at 90.00 yen.
On technical charts, the dollar faces resistance in the 89.70 yen to 90.70 yen area, a zone that contains a Fibonacci retracement level and other resistance levels.
The euro rose 0.9 percent to 120.08 yen, after having hit a high of 120.13 yen, the single currency’s highest level versus the yen since May 2011.
Against the dollar, the euro rose to as high as $1.3404, the European unit’s strongest level since February 2012. The euro last changed hands at $1.3399, up 0.4 percent on the day.
A trader for a Japanese bank in Singapore said the euro’s technical outlook has brightened in the wake of its 2.2 percent rally against the dollar last week.
The weekly Ichimoku chart, a technical analysis tool that is widely used among traders, was now flashing a bullish signal for the euro, he said. The euro had finished last week above resistance near $1.3327, the top of the weekly Ichimoku cloud.
The single currency has rallied after European Central Bank President Mario Draghi, in a news conference last Thursday, gave no indication that the ECB would cut interest rates in the near future.
Draghi’s comments had disappointed euro bears who thought that the ECB would be inclined to cut interest rates in coming months to shore up the wobbly euro zone economy.
