Euro weakens as Greece says it's out of money

The dollar inched up against the yen, coming closer to hitting its year high in Asian trade Monday, with the greenback extending its gains following upbeat U.S. inflation data and comments by Federal Reserve Chairwoman Janet Yellen Friday.

The euro meanwhile fell after Greek leaders said the country won't make InternationaI Monetary Fund repayments that are due in June.

The U.S. currency (USDJPY) touched as high as Yen121.78 before slightly weakening to Yen121.67 around 0250 GMT. That is higher compared with Yen121.55 late Friday in New York.

Getting a boost from upbeat U.S. inflation and Yellen's remarks, the dollar's uptick to its year high of Yen122.04 set on March 10 has now come into sight.

U.S. core inflation in April, excluding volatile food and energy prices, showed the biggest gain since January 2013, while Yellen said the central bank is on track to raise interest rates sometime this year.

A solid gain in the Nikkei Stock Average gave a support to the dollar by allowing selling of the yen, perceived as a safe asset. The benchmark index rose 0.7% midday.

But investors found it difficult to make any major moves, with many overseas investors away on holiday and a lack of fresh trading cues. Financial markets are closed elsewhere in the world including the U.S. for Memorial Day and the U.K. for Spring Bank Holiday.

"Investors were scared of heights," when the dollar hit its year high in March, said Daisaku Ueno, chief FX strategist at Mitsubishi UFJ Morgan Stanley.

But after confirming solid downside support around Yen118 and Yen119, later in the year and then with "investors' eyes accustomed to stay around Yen120" in recent session, the dollar is now positioned better to try its upside against the yen, said Ueno.

Investors showed a muted reaction to Japan's merchandise trade balance for April released earlier Monday by the government.

A month after its first surplus in nearly three years, the world's third largest economy logged a YenY53.4 billion deficit.

The euro (EURUSD) fell to $1.0993 from $1.1017, while the common currency was at Yen133.68 from YYen133.83. Greece said Sunday that it won't have the money it must repay to the International Monetary Fund next month unless it strikes a deal with international creditors over further rescue funding.

"This money will not be given," Interior Minister Nikos Voutsis told privately owned television station Mega (http://www.marketwatch.com/story/greece-wont-meet-imf-repayments-in-june-interior-minister-says-2015-05-24), on Sunday. "It does not exist."

The WSJ Dollar Index, a measure of the dollar against a basket of major currencies, was up 0.03% at 86.23.
