Interesting development.
I have been reading a lot of background on the SVB "bank holiday" this morning.
My only comment is, let's see how it is taken care of over the next 5-business days or so. Right now, this very morning, our government is working with the Fed to see how big of an issue it is. Is it 2008 Redux, or just a minor blip.
With that all written, I would STRONGLY suggest that you have a plan to extract any surplus cash out of your checking/saving's account. Remember, you can always put it back in BUT, when your bank decides to go on holiday, you can not get it out.
