Mother, Mark Carney has consistantly said a no deal would be terrible. Thats his view. His view also is that wage growth is terrible, as is interest rate rises on costs of borrowing. As is inflation on bonds. etc etc you get my drift. It is not Mark Carneys place (nor would we want it to be) to pronounce on social policies. I.e. Have a view on nurses pay for example, or government spending on the armed forces.
He must look solely at UK PLC, and UK PLC using the same central bank policies as the ECB, have done very well for investors. Thats what hes paid to do.
The claim over whether a no deal would indeed be a 'crash' however, is highly debateable. The World Bank (who know a thing or two about WTO and indeed UK PLC) issued their research in September on a 'no-deal' which reverts to WTO and its impacts. Here it is.

In short, they forsee in the event of a 'no deal', UKs exports to EU will decrease by 2%.
To put that in context, our exports to the EU account for 12.6% of GDP, and a contraction of 2% on that, would impact our total GDP by 0.25%.
No where near the last big crash we had in 2009 which saw a 7.2% reduction.
Im not neccesarily a 'no deal' extremist, but I am anti unfounded hysteria that surrounds it.
