Four weeks to go to the BREXIT referendum. The Euro and Sterling are feeling nervous. For Britain to leave the EU would be madness. If the Brits vote to stay, both currencies will have a spike immediately after. In the unlikely event that they vote to leave, the immediate effect might be a down-spike.
