The value of the British Pound (GBP) has dropped dramatically in comparison to the value of the US Dollar (USD) since the result of Sunderland was announced.
At the end of the day, £1 GBP had risen to a high $1.50 USD, with polls suggesting that the UK would vote to Remain in the EU. By the time the result of Sunderland was announced, it had shaved off 6% of its value, dropping to $1.44 USD.
It then dropped further still, ending up as low as $1.36 USD.
This is an unnerving start to the night, as at this early stage such little confidence in the value of the UK could have devastating economic impacts.
