HYSA, almost always. The whole purpose of an emergency fund is unfettered access. A CD locks the money for 3-60 months and charges an early-withdrawal penalty if you break in. The 30-80 basis points you'd pick up in a CD doesn't justify a $1,500 penalty if your car breaks down in month 4. The one exception: a 'no-penalty CD' at a comparable HYSA rate, which gives you both.
Savings account vs MYGA, after tax
Rates used: Savings account 4.00%, the top online savings rate we tracked (bank sites, September 24, 2026); savings rates can change any day; change it to the rate you are offered. MYGA 5.95%, the best A-rated rate we track as of October 13, 2026: Delaware Life Pinnacle Plus 5-year (AM Best A-, negative outlook, 7/31/2026), $100,000 and up, effective October 6, 2026 (Delaware Life rate sheet).
| Savings account, interest taxed every year | $116,604 |
|---|---|
| MYGA, tax-deferred, before tax | $133,507 |
| MYGA after paying tax on all the interest at withdrawal | $126,136 |
| Tax deferral alone adds about | $674 |
| MYGA ahead of the savings account, after tax | $9,531 |
Assumes 22% federal and 0% state income tax, no withdrawals, rates held for the whole term. MYGA interest is taxed as ordinary income when you withdraw it, not as capital gains. Gains taken before age 59 1/2 can owe a 10% IRS penalty, and cashing out early can cost a surrender charge. In an IRA both grow tax-deferred, so the edge there is the rate alone. Bank and credit union deposits are FDIC or NCUA insured up to the limits; a MYGA is backed by the issuing insurer's claims-paying ability and your state's guaranty association up to its limits, not the FDIC.

Emergency fund belongs in a HYSA, not a CD. The purpose of an emergency fund is to be available the instant you need it: same day, no penalty, no friction. A standard CD locks the money for 3 to 60 months and charges 3-12 months of interest as an early-withdrawal penalty if you break in early. That penalty can wipe out a year of yield.
The yield gap between a HYSA and a 6-12 month CD is typically 20-50 basis points. On a $30K emergency fund, that's $60-$150/year. Not worth the flexibility you give up.
Emergencies don't time the CD calendar. The transmission goes out in month 3 of a 12-month CD. The roof leaks in month 9. The kid in college needs $8K in month 5. If your emergency money is locked, you either pay the penalty or rack up credit card debt at 22% APR. Either way the "yield uplift" was a bad trade.
HYSA = always available. That's the feature, and that's why it's worth the slightly lower rate.
You have a $30,000 emergency fund. Two options:
| Vehicle | APY | Year-1 interest | Penalty if you break early |
|---|---|---|---|
| HYSA | 4.25% | $1,275 | $0 |
| 12-month CD | 4.65% | $1,395 | 3 months interest = ~$349 |
| 5-year CD | 4.40% | $1,320 | 6 months interest = ~$660 |
| No-penalty CD | 4.10% | $1,230 | $0 after 7-day initial period |
The 12-month CD picks up $120 of extra annual interest vs. the HYSA, but a single emergency withdrawal in month 4 costs you $349. Worst-case math doesn't work.
The no-penalty CD is closer to a wash. If your bank offers one at a competitive rate, it's a reasonable HYSA substitute. Read the fine print on the access window (most require you wait 7 days after opening before you can withdraw).

| Household | Recommended emergency fund |
|---|---|
| Dual-income W-2, low expenses | 3 months of essential expenses |
| Single-income W-2 | 6 months |
| Self-employed / 1099 | 9-12 months |
| Retired, drawing from portfolio | 12-24 months of expenses (cash bucket strategy) |
| Business owner pre-sale / pre-liquidity event | 12 months + transaction reserves |
For retirees, the emergency fund and the "cash bucket" merge into a single 12-24 month liquid pool that insulates the portfolio from sequence-of-returns risk. Above 24 months, you're typically over-allocated to cash and should look at MYGAs or laddered CDs for the excess.
For the portion of your cash above a fully-funded emergency fund, CDs and MYGAs both make sense. The emergency fund stays in the HYSA. The $50K-$500K of surplus cash beyond that (money you won't touch for 1-10 years) moves to laddered CDs, T-bills, or MYGAs depending on horizon and tax bracket.
