Overview
American Express National Bank is a federally chartered national bank regulated by the Office of the Comptroller of the Currency, headquartered in Sandy, Utah. It is a wholly owned subsidiary of American Express Company, a financial services corporation founded in 1850 and publicly traded on the NYSE under the ticker AXP. American Express National Bank had total assets of approximately $84 billion as of Q4 2025. The brand's 170-plus year history in financial services gives it a level of institutional trust that few direct competitors can match.
The High Yield Savings Account pays 4.15% APY with no minimum deposit requirement and no monthly fee. Interest compounds daily and credits to the account monthly. The rate is unconditional: there is no direct deposit requirement, no minimum balance tier, and no promotional period. However, the account has a practical limitation that matters for people who move money frequently: ACH transfer times at American Express National Bank are among the slowest in the industry. Transfers to and from external bank accounts often take 3 to 5 business days, versus 1 to 3 business days at most competitors and near-instant at some.
The other structural consideration is the app situation. American Express runs its credit card app (the main Amex app) and its savings account app as separate products. Existing Amex cardholders who expect to manage their savings alongside their Blue Cash or Platinum card in one interface will be disappointed to find they need to download and log into a different application. The savings web portal and separate savings app function adequately, but the fragmentation adds friction for everyday use.
Rate History
The American Express HYSA rate has tracked the Federal Reserve rate cycle since 2022, moving from near 0.50% in early 2022 to a peak of approximately 4.65% APY in mid-to-late 2023. The rate has declined to 4.15% as the Fed reduced rates in 2024 and into 2025. American Express has historically positioned the savings rate slightly below the top of the HYSA market, consistent with the premium brand trust it provides. The account is unlikely to lead the market on rate but is equally unlikely to fall far below the competitive tier.

How to Open
Opening an American Express HYSA account takes about five minutes at americanexpress.com/savings or via the dedicated savings app. You will need a Social Security number and an external bank account for the initial ACH funding. Existing Amex cardholders can pre-fill some information from their card account.
- Visit americanexpress.com/savings or download the Amex Savings app
- Complete identity verification with SSN and personal information
- Link an external bank account for the initial deposit via routing and account number
- Fund with any amount via ACH (plan for 3-5 business days for the first transfer)
- Note: this is a separate app from your main American Express credit card app
App and Online Banking Experience
The American Express savings app (separate from the main Amex credit card app) has App Store ratings around 4.2 out of 5 and Google Play ratings near 4.0. The interface is functional and straightforward for a savings-only account: balance display, transfer initiation, and account settings are accessible. The primary friction point is that Amex cardholders must manage two separate applications for their credit cards and their savings account. Unlike Discover, which integrates both on a single login, American Express has not unified these experiences. For infrequent savers who check the account once a month, the app limitation is minor. For those who want a fully integrated experience, Discover or Ally is a better fit.
FDIC Insurance and Safety
American Express National Bank is a nationally chartered bank, Member FDIC (FDIC certificate number 27471). Deposits are insured up to $250,000 per depositor per ownership category, with joint accounts covered up to $500,000. American Express National Bank had total assets of approximately $84 billion as of Q4 2025 and is backed by American Express Company, one of the most recognized financial brands globally.
- Existing American Express cardholders who want to keep everything in the Amex ecosystem

- Those who rarely need to move money quickly and can tolerate slower ACH
