Where to Stash Your Emergency Cash

A financial cushion can improve your ability to survive bad times, but right now that cash may be earning a relatively low interest rate. However, try to think of it as you might insurance: your emergency fund is designed to be there when you need it. Here are some possibilities that balance safety with liquidity:

Interest-bearing checking accounts

Deposit accounts are federally insured up to $100,000, so they're as secure as it gets. Bank deposit balances are insured by the Federal Deposit Insurance Corporation (FDIC); credit union balances are insured by the National Credit Union Administration. Lower costs often permit higher yields on online accounts, and minimum balances for online accounts also are typically low. However, depending on the institution, your access with an online-only account may be somewhat less convenient than you're used to; for example, the number of deposits or check-writing privileges may be limited. An ATM/debit card linked to a checking account is convenient, but if the temptation to use it for a "retail emergency" proves too great, it could end up pulling the stuffing right out of your financial cushion.

High-yield savings accounts

Savings accounts typically offer higher interest rates than checking accounts. Again, some of the best rates may be available online. However, make sure you find out whether the yield quoted is an introductory rate and what minimum balance is required to get it. Also, some high-yield savings accounts require that a certain number of purchases be made using a linked credit or debit card--hardly appropriate for an emergencies-only fund.

Money market savings accounts

A money market savings account (MMA) may offer higher interest than a checking or even a regular savings account, but also may have some restrictions on access; for example, it may limit the number of transfers, withdrawals, or checks, and may require a higher minimum initial deposit or balance. (On the other hand, such constraints may force you to think twice before accessing that money without good cause.) MMAs generally invest in short-term commercial loans, CDs, and government securities.

Money market mutual funds

Money market mutual funds may offer higher rates than checking or savings accounts. Even though they may invest in similar types of securities as money market savings accounts, don't confuse the two. An investment in a money market mutual fund is not insured or guaranteed by the FDIC or any other government agency. Although the fund seeks to preserve the value of your investment at $1 per share, it is possible to lose money by investing in the fund. If you're in a high tax bracket, consider municipal money market funds, which offer the federal tax advantages of muni bonds. A fund that concentrates on munis from your state also may offer state tax benefits.

Laddered cash equivalents

Certificates of deposit (CDs) or short-term Treasury bills provide less liquidity, but a laddering approach could improve your access while still limiting to some extent your ability to raid your fund without a good reason. For example, you might buy six CDs; the first CD matures in one month, the second in two months, the third in three months and so on up to six months. When the first CD matures, you could buy another six-month CD; you'd do the same with each succeeding CD at maturity. That would make some cash available once a month, and laddering lets you adapt to changing interest rates. A similar strategy could be used with short-term T-bills, available in maturities of 4, 13, 26, and 52 weeks. However, be aware that if you need to sell or cash in a CD early, you may have to pay a substantial penalty that could wipe out any incremental yield. In the case of a brokered CD sold before maturity, you also might suffer a loss. Also, interest rates could affect the value of a T-bill sold before it matures.

Short—term bond funds

Sometimes used as an alternative to a money market fund, short-term bond funds have typically offered higher yields with relatively modest increased risk (though they also are not FDIC-insured). However, recent credit market conditions have underscored their hazards. Short-term bond funds may be more stable than long-term funds, but some investors have been surprised at losses resulting from their fund's exposure during the past year's credit turmoil to investments considered relatively safe.

Whatever you use for your cash stash, have a plan for replenishing it after the emergency has passed.
