> With the currency already in freefall amid concern about a so-called hard Brexit, Friday’s slide took it to the weakest level since March 1985.
https://finance.yahoo.com/quote/gbpusd=x?ltr=1 - look at the 5 year view.
The currency took a sharp drop right after the vote, quite possibly as much because the BoE said they'd engage in a massive QE (money printing) program as the vote itself. Since then GBP/USD has acting fairly normal, as in, continuing a general weakening trend that has been going on for several years now. Zooming out to the ten year view shows what an actual freefall looks like as the relatively huge drop from $2 down to $1.50 during the financial crisis hit. The movements of the past few days are quite small relative to that.
But I guess freefall sounds exciting and showing a longer term graph is not.
