That is the Trillion dollar question! There's a lot of cash sitting on the sidelines, and it's unclear whether this is normal family savings - money squirreled away just in case - or proceeds from stock sales in February and March. The former is likely to affect consumer purchases over time; the latter will eventually return to the stock market.
It's hard to know which businesses are thriving in this environment. Clearly Netflix and the cloud SaaS folks are doing great. I'm also seeing a lot of home maintenance workers swamped with business at the moment since everyone is spending so much time at home.
But I've also heard of many commercial projects stopped or outright cancelled. Need any new office buildings now that everyone is working from home, quite possibly well into next year?
Will banks lend that $2T of extra cash? Most likely some of it. But you can be sure they'll be performing extra scrutiny on any business loan or real estate loan, which is pretty much all banks lend to anyway.
Do you still have a job and a paycheck? By a company that's likely to stay in business?
Is your real estate project a warehouse? Great, here's a loan. Office building? Get lost!
