Vanguard does not offer a traditional high yield savings account under its own brand
Vanguard, the investment company, does not issue its own savings account product. If you hold cash at Vanguard, it sits in a money market fund or a sweep account — not a savings account. The distinction matters because the rate you earn, the way the account works, and the protections that cover your money are all different from what you get at a bank.
Vanguard does partner with banks to offer Vanguard Brokerage Link, which connects your Vanguard brokerage account to an external bank savings account. This is a linking service, not a Vanguard product. The savings account itself comes from the partner bank, and the rate depends on which bank you choose.
If you already have a Vanguard brokerage or investment account and want to hold cash there, you have two main paths: keep it in a money market fund, or link an external bank account. Neither is a high yield savings account in the traditional sense.
Key Takeaways
- Vanguard does not issue savings accounts; cash at Vanguard lives in money market funds or sweep accounts tied to your brokerage account.
- Vanguard Brokerage Link lets you connect an external bank savings account to your Vanguard brokerage, but the account and rate come from the partner bank, not Vanguard.
- Money market funds at Vanguard charge expense ratios (typically 0.16% to 0.20% annually) on top of the yield, which reduces your net return.
- If you want a true high yield savings account, you will need to open one at a bank directly; Vanguard can hold the money only if you link that account to your brokerage.
- Cash sweep accounts at Vanguard automatically move uninvested cash into a money market fund or partner bank account, depending on your settings.
How Vanguard handles cash through money market funds
When you deposit cash into a Vanguard brokerage account and do not invest it, it typically goes into a money market fund by default. Vanguard offers several money market funds, including Vanguard Federal Money Market Fund and Vanguard Treasury Money Market Fund. These are mutual funds, not bank accounts, so they are not insured by the FDIC.
Money market funds hold short-term debt instruments — Treasury bills, commercial paper, and bank CDs — and pass the interest to you as a dividend. The rate fluctuates daily based on what those underlying securities yield. You can see the current yield on Vanguard's website, but it changes constantly.
The catch is the expense ratio. Vanguard's money market funds charge between 0.16% and 0.20% per year. If the fund yields 4.50%, you keep roughly 4.30% to 4.34% after the fee. That gap widens when rates are lower and shrinks when rates are higher, but it is always there.
Vanguard Brokerage Link and external bank accounts
If you want actual FDIC insurance and a true savings account rate, Vanguard Brokerage Link lets you connect an external bank account to your Vanguard brokerage. You can link a savings account from any FDIC-insured bank — it does not have to be a Vanguard partner.
The process is straightforward: you provide your external bank's routing and account number, and Vanguard verifies the connection with two small deposits. Once linked, you can transfer money between your Vanguard brokerage and the external savings account. The rate you earn is whatever that bank offers, not a Vanguard rate.
This setup is useful if you want to keep your emergency fund or cash reserves in a high yield savings account at a bank like Marcus, Ally, or American Express Personal Savings, while keeping your investments at Vanguard. You manage two separate logins, but the money moves between them without fees.
Cash sweep accounts and automatic placement
Vanguard also offers cash sweep features, which automatically move uninvested cash into a designated holding place. You can choose where that cash goes: into a money market fund, into a linked external bank account, or into a Vanguard Cash Management Account (if you meet the minimum balance).
The sweep happens when you sell an investment, receive a dividend, or deposit cash. Instead of leaving the money sitting idle, it moves automatically to your chosen destination. This prevents you from accidentally holding cash that earns nothing.
If you set your sweep to a linked external bank account, the cash moves to that bank's savings account at whatever rate that bank currently offers. If you set it to a money market fund, it goes into the fund you selected, and you pay the expense ratio.
Comparing Vanguard money market funds to bank savings accounts
| Feature | Vanguard Money Market Fund | Bank High Yield Savings Account |
|---|---|---|
| FDIC insurance | No | Yes, up to $250,000 |
| Expense ratio | 0.16% to 0.20% per year | None |
| Current yield range | Varies; check Vanguard's site | Typically 4.00% to 5.35% APY |
| Liquidity | Same-day access | Same-day or next-day access |
| Where to open | Inside Vanguard brokerage | At a bank directly |
The main trade-off is insurance versus convenience. A money market fund at Vanguard has no FDIC protection, but it is already inside your brokerage account, so you do not need to manage a separate login. A bank savings account is insured, earns a higher net rate (because there is no expense ratio), but requires you to open and maintain an account at a separate institution.
If you have more than $250,000 in cash, FDIC insurance becomes a real constraint. A single savings account at one bank covers only $250,000. Money market funds have no insurance cap, so they can hold larger amounts, though the risk is different — you are exposed to the fund's underlying holdings rather than a bank's solvency.
When to use each option at Vanguard
Use a money market fund if you are holding cash temporarily while you decide where to invest it, or if you have a small amount (under $10,000) and do not want to manage multiple accounts. The expense ratio is low enough that it does not matter much for short holding periods.
Use a linked external bank account if you want to keep a true emergency fund or savings goal separate from your investments, and you want FDIC insurance. Open a high yield savings account at a bank that offers a competitive rate, then link it to Vanguard so you can move money easily when you need to invest or withdraw.
Use a cash sweep to a bank account if you sell investments frequently and want the proceeds to land in an insured account automatically, rather than sitting in a money market fund while you decide what to do next.
Frequently Asked Questions
Can I get FDIC insurance on cash at Vanguard?
Not directly. Vanguard money market funds are not FDIC-insured. However, if you link an external bank savings account to your Vanguard brokerage through Brokerage Link, that bank account is FDIC-insured up to $250,000. You would need to open the savings account at a bank first, then connect it to Vanguard.
What is the current yield on Vanguard money market funds?
Vanguard publishes the current yield for each money market fund on its website, updated daily. The rate changes constantly based on short-term interest rates. You can compare it to bank savings account rates, but remember to subtract the expense ratio (0.16% to 0.20%) to see your actual net return.
Can I transfer money from a Vanguard money market fund to a bank savings account?
If the bank account is linked through Brokerage Link, yes — you can transfer between them without fees. If it is not linked, you would need to withdraw the money from Vanguard (which takes one to two business days) and then deposit it at the bank separately.
Does Vanguard charge a fee to link an external bank account?
No. Vanguard Brokerage Link is free to set up and use. There are no monthly fees or transfer fees for moving money between your Vanguard brokerage and a linked external account.
What happens to my cash if Vanguard goes out of business?
Cash in a Vanguard money market fund is not protected by FDIC insurance, so it would be at risk. Cash in a linked external bank account is protected by that bank's FDIC insurance. If you want full protection, keep your cash in a linked bank savings account rather than a Vanguard money market fund.
