Current Rate: ~4.00% APY
The AmEx HYSA currently pays approximately 4.00% APY, applied to your entire balance with no tiers and no conditions. You do not need direct deposit, a minimum balance, or any linked account to earn the full rate.
Interest is compounded daily and credited on the last day of each month. If the rate changes, AmEx National Bank notifies existing customers by email — changes typically follow Federal Reserve rate decisions within 1–4 weeks. For rate history and how AmEx compares month-to-month, see the AmEx savings rate guide.
Annual Interest on Common Balances at 4.00% APY
| Balance | Annual interest |
|---|---|
| $5,000 | ~$200 |
| $10,000 | ~$400 |
| $25,000 | ~$1,000 |
| $50,000 | ~$2,000 |
| $100,000 | ~$4,000 |
Worked example: If you park $30,000 in the AmEx HYSA at 4.00% APY for 12 months, you earn roughly $1,200 in interest — with no fees eating into it. Compare that to a typical brick-and-mortar savings account at 0.01% APY, which would earn $3 on the same balance.
How to Open an Account
- Go to americanexpress.com/banking or open the Amex app
- Select Open an Account under High Yield Savings
- If you have an existing AmEx card account, your personal details can be pre-filled
- Provide your SSN or ITIN, address, and a linked external bank account for funding
- Fund the account via ACH transfer — no minimum deposit required
The account is approved instantly in most cases. Note that AmEx does not perform a hard credit pull for savings account applications.
Transfers and Limits
All money movement in and out of the AmEx HYSA goes through ACH transfer. There is no ATM card, debit card, or instant transfer option.
| Transfer direction | Timing |
|---|---|
| External bank → AmEx | 1–3 business days |
| AmEx → external bank | 1–3 business days |
| Wire transfers | Available via online portal only |
The daily ACH limit is $35,000 — lower than Synchrony ($250,000 outbound) and Ally. If you frequently move large sums, this matters. See the full AmEx savings transfer limits guide for details on rolling 5-day caps and how to initiate a wire.
CD Options
AmEx National Bank also offers certificates of deposit (CDs) with terms ranging from 11 to 60 months. CDs lock your rate, which is useful when rates are falling. However, early withdrawal penalties apply. See the AmEx CD rates guide for current rates and term comparisons.
What AmEx Savings Does Not Offer
| Missing feature | What to use instead |
|---|---|
| ATM card | Synchrony Bank (55,000+ Allpoint ATMs) |
| Checking account | Ally Bank (free checking + savings) |
| Zelle | Ally, Chase, Wells Fargo |
| Instant transfers | SoFi, Ally |
| CD bump-up option | Synchrony (bump-up CD available) |
These are structural limits of AmEx National Bank, not policy choices that may change. The bank is savings-only by design. Customer service (1-800-446-6307, 24/7) cannot work around these constraints — see the AmEx savings customer service guide for what support can and cannot resolve.

Verdict
The AmEx High Yield Savings Account is a solid, no-nonsense option for savers who prioritize rate and simplicity over access features. The ~4.00% APY, zero fees, and FDIC insurance check all the core boxes. Where it falls short — no ATM card, lower transfer limits, no checking — are predictable trade-offs for a savings-only online institution. If those constraints do not affect your use case, it is a reliable account that delivers what it promises.
