The downfall of the euro
The massive economic blow caused by the Covid-19 will, most likely, bring an end to the euro. This is something we all should acknowledge and prepare for. It will be the biggest financial earthquake ever, requiring some serious hedging and planning. We have outlined such practices in our Crisis Preparation series.

This will enable Eurozone countries to reboot their economies safer and faster than the US.
My bigger fear is they'll use this crisis to create said Federation. EU member states are currently all drawing their own plans, closing borders as they please, while EU is grasping to remain relevant.
Losing euro will be expensive, but it's probably for the best in the long run. Unless you work at ECB of course, then you'll do whatever it takes to keep your job rescue the euro.
Yeah, an European Federation would be bad news but I doubt it will ever come to that anytime soon. The EU is going through too divisive times for such measures.
Having grown up in a smallish EU country with both national currencies and the Euro, I absolutely don't want to lose the latter. There's just too much friction when hopping borders or doing business when every little country has their own little currency and the banks take their own little cuts whenever money moves to and fro. No thank you.
