Sterling bounces back amid Brexit poll jitters

After more than 24 hours of conflicting polls, spiking currency volatility and suspected fat fingers, sterling is back above where it ended last week.

With just 15 days before the UK votes on whether to remain in the EU, expectations for swings in sterling over the coming month climbed to a fresh seven-year high.

Sterling jumped more than 1% against the dollar in about one minute yesterday just after 2pm in Tokyo, with a trader speculating that a mistyped transaction had triggered automatic orders to sell or buy currencies to avoid losses.
