The euro held steady on Wednesday as investors hoped that last-ditch talks on Greece's debt would see a breakthrough deal that keeps it in the eurozone.

In Tokyo trading, the common currency bought $1.1405 and 135.84 yen, down from $1.1413 and 136.13 yen in New York but well above $1.1357 and 134.70 yen in Tokyo earlier Tuesday.

An article published on the website of Turkmenistan's oil and gas ministry Monday attacked Russia's energy giant Gazprom, calling the company an unreliable partner for the reclusive Central Asian state.

Japanese household spending in 2014 declined at its fastest pace in eight years, official data showed Tuesday, underscoring the impact of the country's first sales tax hike in nearly two decades.

The euro weakened Tuesday after the showdown debt talks between Greece and its creditors collapsed, raising the prospect the country will be dumped out of the eurozone.

Eurozone ministers handed Greece an ultimatum to request an extension to its bailout program on Monday after crunch talks collapsed, deepening a bitter stand-off that risks seeing Athens bid farewell to the euro.

Eurogroup head Jeroen Dijsselbloem said Greece had the rest of the week to request an extension to the program, which expires at the end of the month, challenging Athens to cave in on a dearly held position.

A 14-year-old currency swap accord between Japan and South Korea will not be renewed when it expires later this month, the Bank of Korea said Monday, amid souring bilateral ties.

The $10 billion agreement, originally set up in 2001 and aimed at helping tide one another over financial crises, will end February 23, the  central bank said in a statement.

Japan's economy limped out of recession in the last quarter of 2014, official data showed Monday, but analysts said the weaker-than-expected growth would likely press the central bank to introduce fresh stimulus measures.

The 0.6 percent expansion in the world's number three economy in October-December -- or 2.2 percent on an annualized basis -- follows two consecutive quarters of contraction that came as an April sales tax rise hammered consumer spending.
