Imagine if all countries take the same policy, the global supply chain will soon be connected again and the destruction of the global economy can be avoided. So the V-shaped form of economic recovery can be obtained.
I agree. For such a synchronized economic recovery to take place, nations would need to reopen their economy simultaneously (or within close time frames), inorder to reconnect the supply chain. The United States and China are trade partners and are the highest importers of products from each other. So, if China opens up (as is happening) while the U.S remains closed, there would be slow growth rate as they are working without a major market for their product and would also lack imports.
So while the real economy is trailing, the stock market is doing fine. Dow Jones for example is still positive over 1 year, Euro Stoxx is only slightly down.
This could be a representation of the K-shaped recovery curve; where one sector rebounds due to stimulus or government grants and another continues to slide down or remains stagnant.
I just hope it doesn't hit that bad again!
Keeping to health guidelines would reduce the impact of a second or third wave. Fear index of the pandemic has reduced over the months and people now defy lockdown laws (at least in my area), this increases the possibility of another wave.
