Are you concerned about treasuries? Would you put 1.5 million in SGOV?

Had a recent windfall and this 1.5 is about 1/3 of my total portfolio. Rest is in VT.

I'm unsure what I want to do and may retire early in a year or two. I'm 48 and looking to park this money somewhere safe for 6-24 months. I really don't want to open up 6 bank accounts for FDIC insurance so I'm planning on dumping it all in SGOV.

Is this still a safe option to keep my principal safe?
