We will be doing it two or three different ways for the four of us who bought these CDs.
My wife and I have a bank savings account paying 2.50%, so we will wire the funds directly from NWFCU to the bank savings account. Setting up the wire instructions at NWFCU was easy, and hopefully the actual wire process will go smoothly.
For my mom and my friend, we set up NWFCU as an external account at Vanguard (micro deposits were there in one business day).
For my friend, we probably will buy $50,000 of Treasury money market fund, since that's the minimum, and this gives him the highest taxable-equivalent yield (TEY) for a Vanguard MM fund. The rest might go directly into Short-Term Treasury bond fund, unless he decides to upgrade his old-platform mutual fund account to a brokerage account, in which case we might buy individual Treasuries instead. Once the Treasury MM fund is open, he will move whatever he doesn't anticipate spending in the next year or so into the short-term Treasury fund or individual Treasuries.
For my mom, we probably will transfer most of it to Vanguard Prime MM in her brokerage account, but might also transfer some to her Ally savings account, where the link to NWFCU was established when she funded the CD. Much of it will then be deployed into a ladder of Treasuries and/or CDs out to 2-3 year maturity.
