Faced with a second day of turmoil after Thursday's referendum, which most in markets had thought would deliver a vote in favor of staying in the EU, investors sought safe havens such as the yen, gold and core government debt, Reuters wrote.
British finance minister George Osborne sought to reassure markets, saying the world's fifth-largest economy was strong enough to cope with the Brexit-inspired volatility, but the positive impact on sterling was only fleeting, as noted in the report.

An index of European bank shares fell 7.3%, taking losses in the last two trading days to around 20%. Royal Bank of Scotland shares fell 24% while Barclays shed 18%, Reuters wrote.
Italian banks also suffered. The government was looking at options to help its banks and prevent further share price falls.
