Key Takeaway
Charles Schwab offers some of the most competitive money market funds for investors seeking safety and yield on cash holdings. The Schwab Value Advantage Money Fund (SWVXX) currently offers attractive yields around 4-5% with daily liquidity, while the Schwab US Treasury Money Fund (SNSXX) provides similar returns with the added benefit of state tax exemption. For high-net-worth investors, the ultra share class (SNAXX) delivers higher yields through lower 0.19% expense ratios. Choosing the right fund depends on your tax situation, investment amount, and liquidity needs.
Why Money Market Funds Beat Traditional Savings
In today's interest rate environment, keeping cash in a traditional savings account means leaving money on the table. While the national average savings account pays just 0.57% APY, top Charles Schwab money market funds are delivering yields approaching 5%.
The Yield Gap Explained
Money market funds invest in short-term, high-quality debt securities including Treasury bills, commercial paper, and certificates of deposit. These instruments currently offer yields reflecting the Federal Reserve's elevated interest rate policy.
Unlike savings accounts at banks, money market funds aren't constrained by the same overhead costs and can pass through virtually all yield to investors. This structural advantage becomes increasingly significant as interest rates rise.
Liquidity Without Compromise
Charles Schwab money market funds offer same-day liquidity—you can access your money when needed without penalties or waiting periods. This makes them ideal for emergency funds, short-term savings goals, or cash awaiting investment opportunities.

SWVXX: The Popular Choice
The Schwab Value Advantage Money Fund (SWVXX) stands as Schwab's flagship retail money market fund, attracting billions in assets from investors seeking competitive yields with professional management.
Understanding SWVXX's Investment Approach
SWVXX seeks the highest current income consistent with stability of capital and liquidity. The fund invests in a diversified portfolio of high-quality, short-term money market instruments including commercial paper, certificates of deposit, repurchase agreements, and government securities.
With a 7-day SEC yield typically ranging between 4.5% and 5%, SWVXX offers income substantially above traditional savings vehicles. The fund maintains a stable $1.00 net asset value (NAV), ensuring your principal remains protected.
Tax Considerations for SWVXX
Distributions from SWVXX are subject to both federal and state income taxes. For investors in high-tax states like California or New York, this tax treatment significantly reduces after-tax yield. If you're paying 10% state income tax, a 5% yield effectively becomes 4.5% after state taxes.
For tax-sensitive investors, this makes SWVXX less attractive compared to Treasury-focused alternatives, despite its slightly higher headline yield.
SNSXX: The Tax-Smart Alternative
The Schwab US Treasury Money Fund (SNSXX) invests exclusively in short-term U.S. Treasury bills and related securities. While its yield typically runs slightly below SWVXX, the tax advantages often make it the better choice for many investors.
State Tax Exemption Advantage
Income from U.S. Treasury securities is exempt from state and local income taxes in most jurisdictions. For investors in high-tax states, this exemption significantly boosts after-tax returns.
Consider this example: An investor in California with a 9.3% state tax rate comparing two funds with 4.8% yields:
- SWVXX after-tax yield: 4.8% × (1 - 0.093) = 4.35%
- SNSXX after-tax yield: 4.8% (state tax exempt) = 4.8%
In this scenario, SNSXX delivers an additional 0.45% annually—$450 on a $100,000 investment.
Safety and Stability
SNSXX holds only securities backed by the full faith and credit of the U.S. government. This eliminates credit risk from corporations or financial institutions, making SNSXX among the safest cash investments available.

SNAXX: Institutional-Grade Returns
The Schwab Prime Advantage Money Fund – Ultra Shares (SNAXX) offers the same investment strategy as SWVXX but with a lower 0.19% expense ratio compared to SWVXX's higher retail fee structure.
Minimum Investment Requirements
SNAXX requires a $1 million minimum initial investment, making it accessible primarily to high-net-worth individuals and institutional investors. However, some investors build up to this threshold over time as their portfolios grow.
Yield Advantage
The reduced expense ratio directly translates to higher yields. With lower fees consuming less of the fund's returns, SNAXX typically offers 0.1% to 0.2% higher yields than its retail counterpart. On a $1 million investment, this difference equals $1,000 to $2,000 annually in additional income.
For investors approaching the $1 million threshold, monitoring cash positions and potentially consolidating holdings into SNAXX represents a straightforward way to enhance returns without taking additional risk.
Choosing the Right Fund for Your Situation
Selecting among Schwab's money market options requires evaluating your specific circumstances including tax situation, investment size, and liquidity needs.
For High-Tax-State Residents
If you live in California, New York, New Jersey, or other high-tax jurisdictions, SNSXX generally provides superior after-tax returns despite its slightly lower pre-tax yield. The state tax exemption typically outweighs the modest yield differential.
Run the numbers for your specific tax bracket. The break-even point usually occurs when state taxes exceed 5-7%, depending on the current yield spread between funds.
For Tax-Advantaged Accounts
If you're investing through an IRA, 401(k), or other tax-deferred account, the tax differences between funds become irrelevant. In these situations, simply choose the fund with the highest current yield—typically SWVXX or SNAXX if you meet the minimum.
For Tax-Free Municipal Options
Investors in the highest federal tax brackets may benefit from Schwab's municipal money market funds like SWWXX (Schwab AMT Tax-Free Money Fund). These funds invest in short-term municipal securities and generate income exempt from federal income tax, including the Alternative Minimum Tax (AMT).
The trade-off involves lower nominal yields, but the tax savings often produce superior after-tax returns for top-bracket taxpayers.

Money Market Funds vs. High-Yield Savings
Many investors wonder whether to choose money market funds or high-yield savings accounts for their cash. Both offer competitive yields in the current environment, but important differences exist.
FDIC Insurance Considerations
High-yield savings accounts carry FDIC insurance up to $250,000 per depositor, per bank. Money market funds, while historically extremely safe, lack this government guarantee.
However, Schwab money market funds invest in high-quality, short-term securities and maintain $1.00 NAV stability. The 2008 financial crisis demonstrated that even during extreme stress, money market funds largely preserved investor capital.
Yield Comparison
As of early 2025, top high-yield savings accounts offer approximately 4% APY, while Schwab money market funds deliver yields approaching 5%. This 0.5% to 1% advantage can meaningfully impact returns on larger cash balances.
Liquidity Features
Money market funds offer check-writing privileges and same-day transfers to your Schwab brokerage account for investment opportunities. This seamless integration makes money market funds particularly attractive for investors maintaining cash reserves for market entry.
Practical Implementation Strategies
Successfully integrating money market funds into your financial plan requires thoughtful execution.
Emergency Fund Placement
Money market funds serve as excellent emergency fund vehicles, offering safety, liquidity, and yields that help preserve purchasing power against inflation. Consider maintaining three to six months of expenses in SNSXX or SWVXX rather than traditional savings accounts.
Cash Drag Minimization
Investors often inadvertently accept low yields on cash positions awaiting deployment. By automatically directing idle cash to money market funds, you ensure every dollar works for you while you research and evaluate investment opportunities.
Systematic Investment Approach
For dollar-cost averaging into the market, maintain your scheduled investment funds in a money market account rather than checking or savings. You'll earn competitive yields until deployment, enhancing overall portfolio returns.
Conclusion
Charles Schwab money market funds offer investors a compelling combination of safety, liquidity, and competitive yields in today's interest rate environment. Whether you choose the popular SWVXX, the tax-efficient SNSXX, or the institutional-grade SNAXX depends on your individual tax situation and investment size.
For most investors, the key is avoiding the drag of traditional savings accounts and putting cash to work in vehicles that generate meaningful returns without sacrificing accessibility. The difference between 0.5% and 5% on your cash reserves can amount to thousands of dollars annually.
