Where Should You Keep Your Emergency Fund?
Keep your emergency cushion in a high-yield savings account at a bank insured by the FDIC or a credit union insured by the NCUA. Money you plan to spend on a set schedule, such as a fund for a career change, can go into Treasury bills or CDs that mature in the months you need it.
Where an emergency fund can sit: rates and rules
| Where you hold it | Recent rate | Insured or backed by | Getting the money out |
|---|---|---|---|
| Savings account, national average | 0.37% | FDIC or NCUA, up to $250,000 per depositor per ownership category | Transfer to checking; some banks still cap monthly withdrawals |
| Top online high-yield savings accounts | about 3.10% to 4.35% APY | FDIC or NCUA, if the bank or credit union is insured | Same as any savings account |
| Money market deposit account, national average | 0.63% | FDIC or NCUA, same limit | Same as savings; often includes checks or a debit card |
| Money market mutual fund (brokerage) | 3.70% (7-day yield, fund index) | Not FDIC insured; SIPC does not cover a drop in value | Sell shares, then transfer the cash |
| 12-month CD, national average | 1.73% | FDIC or NCUA, same limit | Early withdrawal costs a penalty set by the bank |
| Treasury bills, 4 to 52 weeks | 4.07% (4-week) to 4.47% (52-week) | U.S. Treasury; not FDIC insured | Paid at maturity; selling early takes a broker |
| Series I savings bonds | 4.26% (bonds issued May to October 2026) | U.S. Treasury | Locked for the first 12 months |

For the emergency cushion: a high-yield savings account
The cushion has to be there the day a car repair or a layoff happens, and it has to be worth the same amount you put in. An insured savings account meets both tests. The FDIC and the NCUA insure savings, money market deposit accounts and CDs up to the limit in the table, per depositor, per institution, for each ownership category.
The national average savings rate is a small fraction of what the top online accounts pay, so where you open the account matters more than which product you pick. Check how long a transfer to your checking account takes, since a high-yield account is often at a different bank from the one you spend from.
Check the withdrawal rules before you deposit. In 2020 the Federal Reserve removed the six-per-month transfer limit from its definition of a savings deposit, but its savings deposit FAQ says banks are allowed to keep enforcing that limit and are not required to drop it. Some still charge a fee after a set number of withdrawals.
Money market account or money market fund?
A money market deposit account is a bank account. It carries the same FDIC or NCUA insurance as savings and often comes with checks or a debit card.
A money market mutual fund is an investment you buy at a brokerage. The SEC’s investor bulletin on money market funds says these funds are not guaranteed by the FDIC and that an investor can lose money in one. SIPC protects customers if a brokerage firm fails, and it does not protect against a decline in the value of securities.
Cash left uninvested at a brokerage often lands in a sweep program. The SEC’s bulletin on cash sweeps explains that some programs move the cash into deposits at partner banks, which are FDIC insured, while others move it into a money market fund, which is not. Your account agreement says which one yours uses.
If you already invest through a brokerage, a government money market fund can hold part of a change fund. For the core emergency cushion, use an insured bank account, since its balance does not move with markets.
For money with a spending date: Treasury bills or a CD ladder
A career-change fund is different from an emergency cushion because you know roughly when you will spend each month of it. That lets part of it sit somewhere that pays at a fixed date.
Treasury bills are sold in terms from 4 to 52 weeks and pay interest at maturity. That interest is subject to federal income tax and exempt from state and local income tax, which raises the after-tax yield for anyone in a state with an income tax. In the table above, the 52-week bill paid more than the national average 12-month CD by a wide margin.
Plan to hold each bill to maturity. A bill bought at TreasuryDirect cannot be sold there; to sell it early you must first hold it for 45 days and then transfer it to a bank or broker, according to TreasuryDirect’s selling rules. A 4-week bill bought there therefore cannot be sold before it matures. Bills bought through a brokerage account can be sold before maturity at that day’s market price.
A CD ladder works the same way inside the deposit-insurance limit: several CDs that mature in the months you plan to spend the money. Federal rules set only a minimum early withdrawal penalty and no maximum, as the OCC’s consumer help site explains, so read the bank’s penalty before you open one.
Places to avoid for money you may need this year
I bonds track inflation and are backed by the U.S. Treasury, but they cannot be cashed for the first 12 months, and cashing one before five years costs the last three months of interest, according to TreasuryDirect. They can hold savings you will not touch for at least a year. They cannot hold an emergency fund you might need next month.
Stock and bond funds can be down on the day you need to sell, and neither FDIC insurance nor SIPC covers that loss. Keep them for goals measured in years.
One way to split the money before a career change
The companion guide, How Big Should Your Emergency Fund Be Before a Career Change?, sizes two amounts: an emergency cushion and a change fund. The split below puts each one where its spending schedule fits.
- Emergency cushion: all of it in an insured high-yield savings account, separate from the account you spend from.
- First two or three months of the change fund: in the same kind of savings account, so rent never waits on a maturity date.
- Remaining months of the change fund: Treasury bills or CDs set to mature one after another, each in the month you expect to need it.
When a bill or CD matures before you need the money, move it to savings and leave it there. Buying a longer bill at that point can leave a month of rent locked up until the new maturity date.
