The dollar stood tall against the yen around 108.29 JPY= after gaining nearly 1 percent on Monday and reaching a one-week high of 108.60. The yen soared to 1-1/2-year highs last week.
"Don't underestimate the power of short covering," Kathy Lien, managing director at BK Asset Management, said in a note to clients.
While the dollar is "still a sell on rallies" against the yen, Lien said the currency could soar to 110 yen quickly if the 20-day simple moving average at 108.83 were broken. "When a currency...squeezes higher quickly, causing investors to panic and abandon their positions, the rally could be sharp and aggressive particularly when positions are skewed so heavily in the opposite direction," she said.
The euro edged up slightly to $1.1386 EUR=.

Fed officials on Monday gave investors no incentive to alter their monetary policy expectations. Chicago Fed President Charles Evans said he favored the current 'wait and see' approach, while Minneapolis Fed President Neel Kashkari said the current policy stance was "about right."

Minneapolis Federal Reserve Bank President Neel Kashkari on Monday signaled his support for the cautious and patient approach to rate hikes laid out by Fed Chair Janet Yellen, saying the current stance of monetary policy is "about right."
While a rate hike in June is "possible," Kashkari sounded happy to keep rates low for now in order to continue bringing workers who have not worked in months or years back into the labor force.
The most recent indications from Fed officials point to two more interest rate hikes this year. Financial markets, however, are barely pricing in one more, and that is not expected until December, after the U.S. presidential election.
