No industry-wide August 2026 change to high-yield savings accounts, or HYSAs, can be verified. Instead, the latest evidence shows bank-specific disclosure dates, variable rates, and several active checking bonuses with important eligibility limits. Savers can verify a 3.40% Marcus APY, while Chase advertises checking bonuses from $400 to $3,000. The main takeaway is to compare dated terms, ongoing fees, deposit requirements, and FDIC limits—not headline numbers alone.

What HYSA terms can savers verify?
Marcus lists a 3.40% annual percentage yield for its Online Savings Account as of July 22, 2026. According to the Marcus official savings page, the account has no fees or minimum deposit. Its rate can change before or after opening, and maximum-balance limits apply. American Express says its hysa rate and APY are variable and may change without notice.
Its disclosure, current August 9, lists no opening fee, minimum deposit, minimum balance, or monthly fee. Interest compounds daily and posts monthly. Capital One's disclosure is effective August 17. Its 360 Performance Savings account pays one variable rate across the entire balance, with no monthly fee or minimum balance. Capital One does not permit direct ATM withdrawals from this savings account.
Why an "August HYSA rate" can be misleading
The banks' disclosures do not share one measurement date. Marcus uses July 22, American Express uses August 9, and Capital One uses August 17. Each bank also reserves the right to change its APY. That means a dated comparison is only a snapshot.
Marcus's verified 3.40% APY should not be compared with an undated or older advertised rate from another bank as though both were available simultaneously. Account mechanics can matter as much as APY. American Express compounds interest daily, while Capital One restricts direct ATM access. A slightly different yield may be less important than fees, withdrawal access, or balance restrictions for a particular saver.
Which checking bonuses are currently documented?
Chase's Total Checking promotion offers $400 to approved new customers who enroll by October 14, 2026. Customers must receive at least $1,000 in qualifying direct deposits within 90 days. Chase says payment arrives within 15 days after the requirements are met, according to its official $400 offer terms. Existing Chase checking customers and certain customers with recently closed accounts are excluded.
After the introductory period, the account carries a $15 monthly fee unless the customer meets a waiver condition. One listed option is receiving $500 in qualifying electronic deposits. Bank of America advertises up to $500 for eligible new checking customers. However, its public landing page does not disclose the qualification thresholds. Readers should review the complete offer terms before assuming they can earn the maximum.
Is Chase's $3,000 offer practical?
Chase Private Client Checking advertises a bonus of up to $3,000, with an October 14, 2026 expiration date. Qualifying new money or securities must arrive within 45 days and remain for 90 days. The top tier requires at least $500,000.
This makes the offer materially different from the $400 Total Checking promotion: the headline reward is larger, but so is the amount of capital required. Before pursuing it, confirm which assets qualify, when the 45-day transfer window begins, and how the 90-day holding period is measured. Treat "up to $3,000" as a tiered maximum, not a standard payment.
Key takeaways before opening an account
Check the complete disclosure available when you apply because HYSA rates can change and bonus pages can omit key thresholds. Save the dated terms, then track enrollment, deposit, transfer, and holding deadlines separately. Use this short review before committing: The FDIC's deposit-insurance guidance covers checking and savings deposits up to $250,000 per depositor, per insured bank, per ownership category.
Accounts in the same category at one bank are combined, so checking and HYSA balances may share that limit. Capital One also warns that Capital One and Discover Bank deposit accounts opened on or after May 18, 2025 are combined for FDIC-coverage calculations. Customers using both brands should total those applicable balances before moving additional cash.
- Confirm that you meet the new-customer definition.
- Identify the exact deposit or direct-deposit requirement.
- Calculate whether monthly fees could reduce the bonus.
- Check withdrawal restrictions and balance limits.
- Review how deposits at related bank brands affect insurance.
