SYDNEY (Bloomberg) - Global financial markets remained delicate as polls and early returns on the British referendum trickled in, with both the pound and US stock futures surrendering early rallies, while gold retreated with crude.
The pound trimmed an advance to the strongest level of the year and equities futures fluctuated as opinion polls following the British vote on its European Union membership diverged. The yen reversed losses.

"As long as things come in as expected on the results, I think you may see more of a flow into the risk markets - equity markets and the higher yielders - and out of the yen, US dollar and even Treasuries."
The debate over Britain's future dominated trading in June, with anxiety over the economic impacts of a Brexit, and the boost it could give to anti-establishment sentiment globally, stoking market volatility around the world.
