Global stocks have rallied, backed by a rise in oil and commodity prices, while the British pound suffered its biggest one-day loss in nearly six years against the US dollar on fears Britain would leave the European Union.
Sterling tumbled to a near seven-year low during the session after popular London Mayor Boris Johnson said he would campaign to leave the EU ahead of a June 23 referendum. The euro fell 0.9 percent.

Benchmark Brent settled up 5.1 percent to US$34.69 a barrel on Monday, while US crude settled up 6.2 percent at US$31.48 a barrel.
Stocks, whose performance has been tightly linked to oil prices, posted solid gains across major markets.
"It still seems like oil, for whatever reason, continues to be what everything is trading off of," said Eric Kuby, chief investment officer at North Star Investment Management Corp in Chicago.
"That's the signal that the world is OK, that oil prices are going up."
The Dow Jones industrial average rose 228.67 points, or 1.39 percent, to 16,620.66, the S&P 500 gained 27.72 points, or 1.45 percent, to 1,945.5 and the Nasdaq Composite added 66.18 points, or 1.47 percent, to 4,570.61.
All 10 major S&P sectors were higher, led by a 2.2 percent increase for the energy sector.
The gains built on last week's strong performance after a poor overall start for US equities in 2016.

Worries about a possible British exit from the EU sent the euro to a near three-week low. Sterling fell 1.8 percent against the greenback and dropped as low as $US1.4057.
"A Brexit would be bad for sterling, but it would also be bad for the euro," said Neil Jones, Mizuho's head of hedge fund sales in London.
The US dollar was up 0.8 percent against a basket of six currencies.
US Treasury prices ended lower as rising stock and oil prices reduced demand for safe haven debt.
Benchmark 10-year notes fell 5/32 in price to yield 1.77 percent, up from 1.75 percent late Friday.
