I'm long GBPJPY, as part of my FX portfolio, I think we might see an increase in FDI in Great Britain, after the Brexit vote. The Yen lets foreign investors acquire free money to invest in US and UK assets. The chart is interesting here, so it's probably a good pair to trade on the long side. The spread in the UK stock market compared to the European one is interesting as well. I like the potential short squeeze in the Pound to further boost this trade once commercial shorts unwind.
