I had opened a taxable account at Vanguard a few years ago that was not labeled brokerage account. I recently made a change to my accounts and moved that money into a brokerage account with a settlement fund. I had to call them and they said that they have been moving people into brokerage accounts. My roll over IRA and Roth both say brokerage accounts.
I see why! I just received an email from them saying that non-brokerage accounts are not insured by SPIC.
For anyone else that did not know that I suggest that you transfer the money like I did.
