If you look at the yearly graph you'll feel a bit better, it's at Feb 2016 levels.
You do realise that the only reason it hit such lows in February was due to Brexit concerns regarding Cameron's re-negotiation, right? Going, don't worry this Brexit has only - so far - caused as much harm as the last time Brexit tanked our exchanges isn't much of a re-assurance. On previous occasions, the markets recovered as people starting thinking Brexit was less likely, that won't happen this time.
