Global stock markets were eerily calm on Friday as Greece teetered on the brink of default that could end with it exiting the euro zone.
European stocks markets were broadly higher, Japan's blue-chip Nikkei closed up almost 1 percent and U.S. stock futures pointed to further gains on Wall Street where the Nasdaq Composite index hit a record intraday high on Thursday.
This comes against a deepening crisis in Greece. Euro zone officials hold an emergency meeting on Monday after failing to reach a cash-for-reforms deal, while talk of capital controls has grown amid reports of a massive outflow of funds from the country in recent days.

"We're beyond the point of just talking and it looks like capital controls will have to be put in place," Craig Erlam, senior market analyst at currency trading firm OANDA, told CNBC.
"We have reached a tipping point and this is not a time to be optimistic in markets."
Analysts said the market resilience may be explained by a view that contagion risks from Greece are seen as lower than a few years ago thanks to measures taken by the European Central Bank as well as smaller countries such as Spain that have strengthened their banking systems.
"It could be that markets think there will be a deal at the last minute or that even if things were to tip over, contagion to the rest of system would be weaker than it was three years ago," Lutfey Siddiqi, global head of emerging markets at UBS, said on CNBC.
The second reason for the gains could be explained by the fact that Friday is a triple witching day, said analysts. This means that contracts for stock index futures, stock index options and stock options all expire on the same day and can lead to market volatility.

"The fact that it is a triple witching day and we have the expiry of options is causing some strange moves in the markets," said OANDA's Erlam.
What's the big deal?
Athens is widely expected to default on a 1.5 billion euro debt payment to the International Monetary Fund on June 30 if it is unable to unlock further aid from its global lenders.
Christian Gattiker, chief strategist and head of research at Julius Baer told CNBC that Greek woes were priced into markets already as seen by the correction in the Dax index.
Germany's benchmark stock index is down more than 6 percent from a high hit above 12,000 in April.
