NEW YORK, June 23 (Reuters) - Sterling climbed to a 2016 high and global stocks rallied as investors bet Britons were likely to vote to remain in the European Union.
Oil prices rose, shrugging off a smaller-than-expected draw in U.S. crude stockpiles, and the safe-haven yen fell against the dollar as the last pre-vote opinion polls show the "Remain" camp holding a small lead. markets are the best judge of what is going to happen, and they are saying that Britain will remain. The key is the strong jump in the pound," said Peter Cardillo, chief market economist at First Standard Financial in New York.
The pound, which has been the lightning rod for opinion on the EU referendum throughout the six-month campaign, was up 0.7 percent at $1.48 GBP= as traders cut their bets on volatility after the vote. GBPVOL=
Wall Street rose nearly 1 percent, with the S&P 500 approaching all-time highs. MSCI's 46-country All World index up 0.9 percent at its highest in almost two weeks .MIWD00000PUS .
The advance on Wall Street tracked European and Asian markets. London's FTSE .FTSE rose 0.5 percent but was off earlier highs. Germany's DAX .GDAXI and France's CAC 40 .FCHI rose around 1 percent. In Tokyo, the Nikkei .N225 closed up 1.1 percent.
With the polls still tight and having proved unreliable in Britain's general election last year, caution remained, however.
"Everybody is a bit shell-shocked at the way the market has moved so aggressively (towards Britain remaining in the EU)," said Saxo Bank's head of FX strategy John Hardy.
"If you are stuck with a short position, you are being forced out without even knowing the result, but what this also means is that a Brexit result is now a catastrophic risk."
