    TL;DR

    • Higher yield: CDs and direct Treasuries earn 0.25–0.75% more than HYSAs in exchange for locking in your cash
    • Best for defined timelines: Ideal for money you won't need for 3–12+ months (e.g., a future down payment)
    • Lock in before rate cuts: If the Fed is expected to cut rates, securing a fixed rate today can pay off significantly

    Beyond high-yield savings accounts and Treasury money market funds, other cash equivalents can provide attractive returns while maintaining safety. These options include Certificates of Deposit (CDs) and U.S. Treasuries.

    These instruments can be considered cash equivalents because they're risk-free (that is, you won't lose any money). However, they come with a different set of trade-offs compared to more liquid alternatives.

    Pros

    You can generate a higher return than a high-yield savings account, often by 0.25-0.75 percentage points or more.

    Cons

    You have to lock in your cash for the duration of the CD or Treasury, reducing your liquidity and flexibility.

    You'd have to personally weigh whether the "lock-in" (e.g., illiquidity) is worth the higher yield. This decision depends on your personal financial situation, interest rate environment, and need for immediate access to funds.

    Strategic Timing with Interest Rates

    Locking in Higher Rates

    Strategic timing with CDs and Treasuries can pay off significantly, especially if you can forecast a cut in interest rates. By opening a CD right before an anticipated rate decrease, you can lock in higher returns for the duration of the term.

    "When the Fed decided to cut rates to near-zero in March 2020 in response to COVID-19, I put a portion of my emergency fund into a CD offered by Marcus at 2.5% for 1.5 years. Rates continued to stay near-zero until early-2022, so this decision paid off."

    Current Rate Environment

    The next set of rate cuts are forecasted to start in mid-2024, so if you choose to go the CD or Treasury route, it would likely be best to do so sometime in late spring or early summer.

    Timing the market perfectly is always challenging, but with rates expected to decline in the coming months, it may be worth considering locking in current rates before they fall.

    When to Consider CDs or Treasuries

    These cash equivalents are particularly suited for:

    • A portion of your emergency fund that you're confident you won't need immediate access to
    • Saving for a specific goal with a defined timeline (e.g., home down payment in 1-2 years)
    • When you expect interest rates to decline in the near future
    • When the premium over high-yield savings accounts is substantial enough to justify the reduced liquidity

    Creating a CD Ladder

    One popular strategy to balance higher returns with liquidity needs is creating a CD ladder. This involves buying CDs with staggered maturity dates (e.g., 3-month, 6-month, 9-month, and 12-month CDs). As each CD matures, you can either use the funds if needed or roll them into a new CD at the end of your ladder, maintaining a continuous cycle of maturing CDs.

    Ultimately, CDs and Treasuries represent a middle ground between the complete liquidity of savings accounts and the higher returns (but greater volatility) of investments like stocks and bonds. The right choice depends on your personal liquidity needs, interest rate expectations, and overall financial plan.
