Berkshire Hathaway's Eurobonds
Berkshire Hathaway CEO Warren Buffett believes Greece leaving the euro could be a positive moveReuters

Warren Buffett, billionaire investor and CEO of Berkshire Hathaway, said Greece's possible exit from the eurozone could be beneficial for the region.

"If it turns out the Greeks leave, that may not be a bad thing for the euro," Buffett said in an interview with CNBC.

"If everybody learns that the rules mean something and if they come to general agreement about fiscal policy among members or something of the sort, they mean business, that could be a good thing."

Greece, which suffered hard from the eurozone debt crisis, was bailed out by a troika of lenders. The newly elected government in Greece is not happy with the terms of its €240bn (£175bn, $259bn) bailout and has threatened to exit the single-currency region.

Earlier, the talks between Athens and its lenders failed, as the International Monetary Fund and the European Union found a package of reforms proposed by Athens to unlock aid as unrealistic.

Greece would run out of money in a few weeks, if it fails to convince its lenders and secure financial help.

"I've thought that the euro had structural problems right from the moment that it was put it in, which does not mean it will necessarily fail," Buffett said.

"You can adapt to those structural problems, but maybe some countries won't adapt and they won't be in. It's not ordained that the euro has to have exactly the members that it has today."
