Vanguard Treasury Money Market Fund or VUSXX Yield
The Vanguard Treasury Money Market Fund (Ticker: VUSXX) has become a popular destination for investors looking to protect capital while earning a competitive interest rate on their cash. As economic uncertainty and fluctuating interest rates persist in 2025, understanding the mechanics behind the VUSXX yield can help you make smarter, more informed decisions.

What Is the VUSXX SEC Yield?
The VUSXX SEC yield is a standardized formula developed by the U.S. Securities and Exchange Commission to make it easier for investors to compare money market funds. It represents the fund’s income over the past seven days, annualized and net of expenses.
For example, if VUSXX earns a consistent amount of interest income each day, the SEC yield tells you how much you’d earn in a year if that rate stayed steady. It’s updated daily and offers a snapshot of recent performance rather than a forecast of future returns.

Why Does the VUSXX Yield Fluctuate?
The VUSXX yield closely tracks the Federal Reserve’s short-term interest rate decisions. Since VUSXX invests exclusively in U.S. Treasury obligations and repurchase agreements collateralized by Treasuries, its yield rises and falls as Treasury yields change.
In early 2025, the Fed has continued to prioritize inflation control, keeping interest rates elevated. This has helped maintain a higher VUSXX current yield, which remains appealing to both individual and institutional investors looking for a low-risk, liquid investment.
For current policy decisions and rate changes, refer to the Federal Reserve’s official site.
VUSXX Current Yield Snapshot (as of Q1 2025)
| Metric | Value |
|---|---|
| 7-Day SEC Yield | 5.21% |
| Expense Ratio | 0.09% |
| NAV Stability | Constant $1.00 |
Note: These figures reflect publicly reported data as of March 2025. Please verify the latest yield directly on the Vanguard website.
How the VUSXX 7-Day Yield Works
The VUSXX 7-day yield is calculated using the fund’s net income over the last seven days, divided by its average assets, and then annualized. While this may seem technical, it essentially tells you what your annual return would be if the fund continued earning at its current pace.
Example: If you invested $10,000 and the 7-day yield is 5.21%, you’d expect to earn approximately $521 over the next 12 months — assuming constant rates, which is unlikely. Still, this metric provides a useful benchmark.
Keep in mind that the 7-day yield reflects historical data, not a guarantee of future returns. Treasury yields, and therefore money market fund yields, are subject to rapid change based on economic policy and market forces.
VUSXX vs Other Money Market Funds
What sets VUSXX apart is its pure exposure to U.S. Treasury-backed instruments. Many other money market funds invest in corporate paper, municipal bonds, or a mixture of instruments. These funds may offer slightly higher yields but also carry marginally more credit risk.
