Money Market Fund Accounts in Budget
I recently opened a Vanguard Cash Plus account. The base account works similarly to a high yield savings account and I had no problem linking my YNAB account to it. However, my main purpose in opening this account was to buy shares in a US Treasury money market fund. On the Vanguard side, this can be done by using the money in the base account to purchase one of several money market shares, which then show up under the account listing. However, on the YNAB side, the money disappears (is withdrawn) from the Vanguard Cash Plus account and doesn't appear anywhere else.
I thought perhaps that the money market fund might be considered a secondary account and tried creating another Vanguard account in YNAB and also linking it to Vanguard, but no dice. There is no secondary account on the Vangaurd side. So, I'm stuck with two Vanguard accounts in YNAB. One directly links to my Vanguard cash account, but shows a zero balance, and the other one is unlinked, so I have to update my actual balance manually.
Is there any better way of handling this? I don't want to put the Vanguard money market under tracking account becuse, unlike most investments, this IS meant to be part of my budget. It's basically a very safe and largely liquid way of storing some of my money.
