Ways to Manage Idle USD Funds in US Stock Accounts

Money Market Funds

You can choose money market funds to manage idle funds in your US stock account. Money market funds are mutual funds that primarily invest in high-quality short-term debt instruments, such as Treasury bills, commercial paper, and bank certificates of deposit. These products aim to maximize current income while maintaining liquidity and capital safety. You can subscribe or redeem at any time, with funds typically available in 1-2 business days. Money market fund yields are stable, with mainstream products in 2024 offering 7-day annualized yields of about 3.6% to 3.9%. The table below summarizes the main features of money market funds:

Short-Term Treasury ETFs

You can also consider short-term Treasury ETFs. These products primarily invest in U.S. Treasury securities with maturities usually within 1 year. Short-term Treasury ETFs have extremely low risk and strong liquidity, allowing you to buy and sell like stocks during trading hours. Yields are slightly higher than savings deposits and typically correlate with Fed rate changes. They suit investors with high principal safety requirements who want flexible allocation of idle US stock account funds.

Broker Cash Management Services

Many US stock brokers provide cash management services for clients. You can automatically sweep idle funds into the broker’s cash management account to earn interest higher than ordinary savings deposits. Funds are available anytime, with no need for advance redemption when trading US stocks or transferring. Broker cash management products typically invest in money market instruments, with yields close to money market funds, excellent liquidity, and suitability for frequent traders or users needing high liquidity.

USD Fixed Deposits

If you prioritize returns, you can choose USD fixed deposits. USD fixed deposits are offered by banks or brokers, with terms ranging from 1 month to 12 months. You need to lock funds during the deposit period, with penalties for early withdrawal. USD fixed deposit annualized yields are usually higher than money market funds and cash management, but liquidity is poorer. They suit investors who do not need to use US stock account idle funds in the short term and seek higher returns.

You can flexibly choose the above methods to manage idle funds in your US stock account based on your liquidity and return needs.

Yield, Liquidity, and Risk Comparison

Annualized Yield

When choosing wealth management products for idle funds in US stock accounts, you first focus on annualized yield. Different products show clear yield differences. The table below shows current annualized yields and expected future trends for mainstream USD cash management products:

You can see that money market funds and extended cash portfolios currently have similar yields. If the Fed cuts rates, money market fund yields will be directly affected. Extended cash portfolios offer the chance to lock in higher returns for certain periods, suitable for users seeking stable yields.

Liquidity

Liquidity determines how quickly you can convert funds to cash. Starting May 28, 2024, the U.S. securities settlement cycle shortened from T+2 to T+1. You can now buy and sell most US stock-related products with faster fund availability.
In money market funds, short-term Treasury ETFs, and broker cash management, you typically achieve T+1 settlement, significantly improving fund allocation efficiency. USD fixed deposits offer higher yields but require locking funds, with interest penalties for early withdrawal. If you have high requirements for fund flexibility, prioritize products with strong liquidity.

Tip: T+1 settlement makes fund management and reinvestment more efficient, reducing wait times and liquidity risks.

Risk Analysis

When selecting wealth management products, you cannot ignore risk factors. The table below summarizes core risks of major USD cash management products:

In money market funds and short-term Treasury ETFs, you typically face liquidity transformation risk and potential impacts from large-scale redemptions. Broker cash management and USD fixed deposits have lower risks but may still be affected in extreme market conditions. You should allocate idle US stock account funds reasonably based on your risk tolerance, balancing returns and safety.

Investment Threshold and Operation Process

Investment Starting Point

When choosing wealth management products for idle funds in US stock accounts, you first need to understand the minimum investment thresholds for various products. Different products have varying starting capital requirements. Some cash management accounts support zero threshold, while money market funds and broker-issued CDs have certain minimums. The table below summarizes minimum investment requirements for mainstream USD cash management products:

You can flexibly choose based on your fund size. If you want anytime deposits and withdrawals, cash management accounts and some money funds are more suitable. For higher returns, consider fixed deposits but meet higher starting amounts.

Account Opening and Purchase Process

When purchasing USD cash management products on US stock broker platforms, you need to complete the following main steps:

1. Submit personal information, including name, Social Security number or taxpayer ID, address, phone, email, date of birth, ID information, employment status, annual income, net worth, investment objectives, investment experience, etc.

Investment Recommendations and Notes

Recommendations for Conservative Investors

If you are a conservative investor, prioritize principal safety and liquidity. It is recommended to maintain at least six months of living or operating cash reserves, allocating short-term (0-6 months) funds to savings accounts, checking accounts, money market funds, or U.S. Treasury bills. For 6 months to 3 years funds, choose 12-month fixed deposits, Treasury bills, or short-term bonds. Funds not needed for over three years can consider long-term fixed deposits or fixed-maturity bonds. Through layered cash management, you can balance liquidity and returns while effectively diversifying risks.

• Maintain six months cash reserves
• Place short-term funds in high-liquidity accounts
• Layer mid-to-long-term funds to enhance returns

Liquidity-Priority Recommendations

If you prioritize fund flexibility, choose products with strong liquidity. Money market funds, ultra-short funds, and customized portfolios can meet different liquidity needs. You can refer to the table below:

You can place 1-day to 3-month funds in trading-level products, 3- to 12-month funds in strategic level, and 12- to 24-month funds in opportunity-level products, balancing liquidity and returns.

Return-Priority Recommendations

If you pursue higher returns, focus on cash management products with higher annualized yields. For example, US Premium Cash Management Fund currently yields 5.12%. However, note that ETF and mutual fund NAVs fluctuate, and past performance does not guarantee future results. You can enhance overall returns by diversifying across different maturities and types.

Risk Warnings

When managing idle funds in US stock accounts, focus on the following risks:

• Avoid over-concentration in a single product or market
• Avoid frequent asset allocation adjustments based on short-term performance
• Understand that “more trading” does not equal “more progress”
• Regularly rebalance portfolios to prevent deviation from goals

Also pay attention to regulatory protections. Vanguard Cash Plus Account and brokered CDs are protected by FDIC insurance, while money market funds in brokerage accounts are protected by SIPC. Choose suitable products based on your needs to ensure fund safety.

When selecting products, prioritize the three key elements of liquidity, risk, and returns, allocate rationally, and avoid common pitfalls.

You can manage idle funds in US stock accounts through various methods like money market funds, short-term Treasury ETFs, broker cash management, and USD fixed deposits. Each product has unique features in safety, liquidity, and returns. The table below briefly compares two mainstream product types:

You need to reasonably allocate cash management tools of different maturities based on your risk tolerance, fund usage time, and financial goals.
