The pound jumped the most against the dollar in the past seven years, as traders reconsidered the likelihood of Britain leaving the European Union.

The pound reached $ 1.4693, an increase of more than three cents, or 2.34%, the biggest increase in a single day since March 2009.

The rebound followed by several interviews over the weekend, which suggested a very tight race, but that leaves the campaign may lose a little momentum.

FTSE 100 index also rose, with shares closing 3% higher on Monday.

This is the biggest one day gain since February.

The pound has fallen sharply during the past week, after public opinion polls show seems Holidays campaign is playing a leading role.

But figures from the Commodity Futures Trading Commission, the US regulator on the market, offered a wide variation in the trading sentiment on Friday.

These data show that at the end of last week, the currency speculators had already begun to retreat pound again by lowering their bets against the currency.

This contrasts strongly with the first week of June, during which time traders betting against the pound rose to its highest level in the past three years.

However, analysts say, it is likely to be more volatility this week.

"After a major moves sterling over the past two days and limited risk premium in the price at the moment, the pound sterling now looks more vulnerable to the negative surprise from the polls," said ING strategist Peter Krpata in a research note.
