As mentioned, the absolute impact will be after Brexit, but it's encouraging that the market seems to be stable and rallying in some aspects despite relatively high uncertainty.
2 interesting things I've noticed:
1. Brexit has definitely broken political and economic expectations, and the conventional models. Manufacturing PMI's rebounce was the biggest 1 month increase in 25 years, and services PMI's rebounce was the biggest in its history. PMI is usually accurate to the extent that central banks rely on them partly to decide monetary policies, such as BoE's decision last month. Polls and private polls all pointed towards a Remain victory hence the massive rise in GBP, before plummeting as the referendum night progressed.
Brexit and it's effects are definitely unprecedented and whether you agree with Brexit or not, I think we can all agree that there is a huge political and economic lesson to learn here.
2. Less significant point, but it's interesting that the OP seems to be the optimistic one here. I just hope that nobody wishes harm on the UK in order to prove ones point. We should all celebrate any good signs that indicates a successful Brexit.
