Should I put 10k emergency fund in HYSA or brokerage MM like VMFXX?

**For an emergency fund, a brokerage money market fund (MMF) like VMFXX might be a better choice than a bond ETF like HYSA.** Here's why: 1. **Liquidity and Risk Profile**: MMFs like VMFXX are designed to maintain a high level of liquidity, which is crucial for an emergency fund. They invest in short-term, high-quality securities, ensuring that the fund can be quickly converted to cash without significant losses. Bond ETFs like HYSA, although diversified, can still be subject to credit and interest rate risks, which might not be ideal for a fund that needs to be readily accessible. 2. **Expense Ratio and Management Style**: MMFs typically have lower expense ratios compared to actively managed funds. VMFXX, for instance, has an expense ratio of 0.01%, which is significantly lower than the average MMF. HYSA, being a passive ETF, also has an expense ratio, but the exact figure is not available. The lower expense ratio means that your money is working harder for you. Passive management styles like HYSA's are suitable for long-term holdings but might not be the best for an emergency fund due to potential market volatility. 3. **Dividend Frequency and Yield**: HYSA distributes dividends monthly, which might be advantageous if you need regular income. However, for an emergency fund, the priority should be preserving capital rather than generating income. MMFs like VMFXX distribute dividends regularly but at a lower rate, focusing on maintaining stability rather than yield. 4. **Market Conditions**: In times of market stress, MMFs can serve as a safe haven due to their short-term, high-quality asset holdings. This can be particularly important during economic downturns when liquidity might become a premium. In conclusion, while HYSA might offer a higher yield and diversification benefits, VMFXX or a similar MMF could be a more suitable choice for an emergency fund due to its liquidity, lower expense ratio, and stability. However, it's important to consider your personal risk tolerance and the specific needs of your emergency fund. If you need the highest possible liquidity and are comfortable with a lower yield, an MMF might be the better choice.
