COMMENT FROM FIRST LINK: Some key concepts: "“Sometimes it’s kind of relevant to panic. I would recommend you panic… You’ve seen the biggest waterfall decline in M2 right now. M2 is deposits, not loans. That’s the deposits fleeing the system and going into money market funds. That could reach a crescendo where the Treasury and the Fed may have to come in and actually restrict your right as a US citizen to pull money out of the US banking sector.”"
So, there is a bank run. But people are pulling money out of deposits and putting them in Money Market Accounts. Money Market accounts are traded on Wall Street. If the Stock Market closes, Money Market accounts are off-limits.
He recommends long term Treasuries.
My thoughts, skip the Money Market accounts and Treasuries. Go for a time tested investment.
