Reuters sources report

The ECB asked banks to detail how they would deal with a shock to markets and changes they may have to make to their business models.

The story has one interesting note, citing a banking consultant at Accenture. He said most banks were vetting and hedging trading positions to avoid losses. That will lead to a slow unwind after the vote that will put a big under GBP, perhaps more than is priced in now.

Overall, does anyone else think the doomsayers about a Brexit are overstating the consequences?

There's a cottage industry of fearmongering. The headline we'll see is "50 million UK jobs to disappear in Brexit".

The UK will be fine either way.
