With oil prices in the dumps, some of the weaker oil export-heavy countries on this list may be interesting to watch regarding sovereign defaults:

It's probably safe to say we'll see a lot of permanent business closures as a result of these shutdowns. It will take years to recover those jobs.
It would certainly be so if there were no government support of small businesses. Yes, small companies can't survive without bringing in money, and they can't earn money while being closed, but if the government gives them the money they lack, they survive.
Not sure about other countries but the US bailout money are loans, not gifts. These businesses are taking on massive debts to keep afloat. The longer this goes on, the worst shape they'll be in when they do reopen. Since the loans will be forgiven if they default, businesses have some incentive to take the loans now and just close up shop later. It'll be interesting to see what happens in a month or two (regarding defaults and bankruptcies) when it's expected that most states will start reopening.
