Emergency-fund vehicles compared — July 2026
| Vehicle | Typical rate now | Access | Principal risk | Backing | Best for |
|---|---|---|---|---|---|
High-yield savings (HYSA)Core pick | 4.40% APY | Same / next day | None | FDIC | The core emergency fund |
Money market account | 4.10% APY | Same / next day | None | FDIC | Equivalent to a HYSA — pick whichever pays more |
Short CD (3–6 mo) | up to 4.15% APY | Locked until maturity | None if held to maturity | FDIC | A stable slice you won't touch |
T-bills / Treasury money-market fund | Set by the short-term Treasury market | Days (T-bills) / same-day (fund) | Minimal | U.S. Treasury | Above-FDIC balances; state-tax edge |
Deposit rates (HYSA, money market, CD) are the best live rates across the 104 banks SwitchWize tracks, updated July 9, 2026. Treasury bill and Treasury money-market yields move with the short-term Treasury market and are not a deposit product we track, so no single rate is quoted — check current yields at TreasuryDirect.

How we calculated this
Expected net value = after-tax interest − fees − liquidity penalty − simplicity penalty − early-withdrawal risk
Assumptions
- •The emergency fund principal stays constant for one year.
- •Tax estimates are broad educational approximations, not tax advice.
- •Treasury-heavy products are modeled as exempt from state income tax.
- •Liquidity penalties represent the cost of slower access, not an actual fee.
Safety & friction
HYSA, MMDA, and CDs are treated as deposit products for this comparison.
$25,000 remains liquid in the deterministic split.
Why ranked here: High-yield savings has the strongest eligible expected net value after tax, liquidity, simplicity, and early-withdrawal adjustments.

The rule behind the recommendation
An emergency fund exists to be reached instantly, so its first line always sits in a top HYSA — instant access, FDIC-insured, ~4.40% APY. If you could need the money at any time, keep 100% there. If part of it is genuinely stable, keep roughly one to two months of expenses liquid and ladder the remainder in short CDs or T-bills so something matures regularly. Above $250,000 at one bank, spread across banks or use Treasury instruments for backing above the insured limit.
Frequently asked questions
Where should I keep my emergency fund?
Keep the core in a high-yield savings account — its job is instant access, and a top HYSA pays about 4.40% APY today with same- or next-day withdrawals and FDIC insurance. Liquidity beats yield for money you may need without warning, so the first line of the fund should sit somewhere you can reach immediately, not in anything with a lock-up.
HYSA vs money market vs CD for an emergency fund?
Access wins. A high-yield savings account (~4.40% APY) and a money market account (~4.10% APY) are functionally equivalent — both FDIC-insured with fast access — so pick whichever pays more. A CD (up to 4.15% APY) locks your money until maturity; the early-withdrawal penalty makes it the wrong trade for money you might need on short notice.
How much of my emergency fund should be liquid?
Keep roughly one to two months of expenses fully liquid in a HYSA so you can cover an immediate shock without breaking anything. If you hold more than that and some is genuinely stable, ladder the remainder in short CDs or Treasury bills so something matures regularly — accepting the lock-up only on the portion you are unlikely to need at a moment's notice.
Is a CD or a T-bill better for an emergency fund?
Neither should hold the liquid core — that belongs in a HYSA. For a stable slice you won't touch, a short CD is FDIC-insured but penalizes early withdrawal. Treasury bills and Treasury money-market funds are backed by the U.S. government rather than FDIC insurance, which matters above the FDIC limit, and their interest is exempt from state income tax. Both carry a lock-up or settlement delay, so they fit the planned-stable portion of a fund.
