The biggest recent "gyration" of the pound by a country mile took place immediately after the pro-brexit vote, so don't blame me! In fact, if you go back to Nigel's graph and click on the one-year tab you'll see that the pound has been pretty steady since around the end of August, with just the little flickers up and down that are typical of currency fluctuations in general. It's true that the pound essayed a slightly bigger flicker this week, but in spite of all the brave brexiteer talk of a breakthrough it's business as usual today. Interesting that when the brexiteers won the fight and the pound plunged, it's a "correction." But when those much littler "gyrations" take place, it's all the fault of us whingeing remoaners. Very entertaining!
