So, economist's consensus seem to think that the impact will be rather catastrophic:

And that is purely based on the possibility of a brexit.

Other indexes are also falling, so thanks, UK, for ruining global economy.

(That's meant to be ... partially ... a joke, sot don't take it too seriously)

Status quo will always return.

UK will be fine, go Brexit! 

Edit: THe world will be fine as well. Go Brexit!

Economists do seem to think otherwise... 

And not as a joke either, lots of real money is being moved

Nothing like threatening people with less [monetary] security to ensure they give up the freedom to choose for themselves.

for US, short term panic. Then once everyone realizes this helps the US things will recover. The UK? It should be beneficially long term, but it will be a bloodbath until everything sorts out.

Can only hope this will cause a stock market crash.

There is no question that products will become more expensive by quite a bit in the near future, could hurt working class.

That is not exactly fair, when UK just took itself out of a bigger market, so of course they would recollate monetary goods and services to where the bigger markets are. 

Wonder if this will result in the Scotland trying to leave again. 

There are fundamental problems with economists :

- they are comparing any impactful change with the current situation like if everything is going well, based solely on the fact we enjoy a mildly growing GDP and stock market. But that is a fiction ! We are currently in a situation where we have to print money and create debt at a level never seen before, we are destroying middle class, unemployment rate is high and rising, and as far as Europe is concerned we just can't see any bright future. It's like telling a junky should not stop drug because he will have it hard for a few months. Let's take current trends and compare with the next 30 years in the current system. Not only it doesn't look bright at all, but it doesn't even seem sustainable. Ask greeks.

- Their economic "analysis" is mostly based on GDP per country, but anyone know how much it is nowadays disconnected from prosperity. France and most European countries tripled their GDP in the last 30 years, are we 3 times better ? No, for 2 reasons. One, whatever the GDP is, if the money flows to rich people and also to the poor that can't anymore have a decent job, we don't get any better. Two, the GDP measure anything that can generate money. Make a fire in a forest, you create GDP, give money out of national debt to a poor, it creates GDP. GDP is a bad measure of prosperity.

- They are mostly not economists, but financial analysts. And they are not neutral, they are guided by their own interets. Will the market go down or up, that's what matter. And not only that, but they are the very people that decide if it goes up or down. Bloomberg and all, if they think the UK market will not go up, it will not, period.

Anyway, it will be hard, money will flow out, the pound will drawn, debt and unemployment will rise, the City will lose some strength. But I believe it is what it takes. And I believe we should not be afraid to dare. Have you ever seen some company or person successful without taking any risk, based on the short term outcome ?
