There was no single marketwide APY or bank-bonus reset in September 2026. Instead, savings rates remained bank-specific while several valuable promotions approached deadlines. APY, or annual percentage yield, reflects the interest an account earns over a year with compounding. Readers should focus on balance requirements, qualifying activity, fees, and deadlines—not headline numbers alone.

What changed with savings APYs?
bankrate reported leading high-yield savings APYs of up to 4.10%, compared with a 0.63% national average. However, each bank controls its own rate and may change it independently, so the September picture is a collection of individual offers rather than one coordinated change. The highest advertised rate may also apply only to certain balances.
CIT Bank's Platinum Savings account, for example, requires at least $5,000 to earn its 4.10% APY, according to Bankrate's September 2026 comparison. A smaller deposit would not receive that headline yield. Before moving savings, check:.
- The balance needed to earn the advertised APY
- Whether different balance tiers receive different rates
- Whether the rate can change after opening
- How the account's return compares at your actual deposit amount
Why the Federal Reserve still matters
The Federal Reserve held its target federal-funds range at 3.50%–3.75% on july 29. That means September did not begin with a confirmed Fed-driven deposit-rate reset. The next major event to watch is the Fed's September 15–16 meeting, as documented in the Federal Reserve's July decision.
Any later bank APY changes would still depend on each institution's decisions rather than taking effect automatically across the market. This distinction matters when choosing between accounts. A strong APY available now is concrete, while expectations about future rates remain uncertain.
Which personal-account bonuses are expiring?
TD Bank's promotion runs through September 30 and offers up to $500 across eligible personal accounts. Beyond Checking pays $300 after $2,500 in qualifying direct deposits, while Complete Checking pays $200 after $500. Signature Savings offers $200 after maintaining $10,000. Qualifying TD deposits are limited to payroll, pension, or government benefits.
Existing or recent former customers and previous bonus recipients may be excluded, and TD may reclaim the bonus if the account closes within six months. Readers should review the TD Bank promotion and eligibility terms before applying. Eastern Bank's regional offer expires sooner, on September 14. Eligible new customers in Massachusetts, New Hampshire, Maine, or Rhode Island can earn $350 with $3,000 in qualifying direct deposits and $250 by holding $15,000 in savings. Completing both adds another $150, bringing the possible total to $750.
The business-checking deadline comes first
Wells Fargo's new-business-checking promotion ends September 8, making it the earliest deadline among these featured offers. It pays $400, $550, or $825 based on a day-30 deposit of $2,500, $10,000, or $25,000. The required balance must remain in the account through day 60, and the customer must complete five qualifying transactions.
Wells Fargo lists those requirements in its business-checking bonus offer. The largest payout is not necessarily the most efficient choice. Committing $25,000 for an $825 bonus may be less practical than earning a smaller bonus with money that would otherwise remain available.
How to compare APY and bonus value
A bonus provides a fixed payment after specified tasks, while APY produces interest based on the deposited balance and time held. Compare both in dollars over the period you realistically expect to keep the account.
For each offer, write down: Federal advertising rules require a stated bank bonus to be accompanied by disclosures covering APY, time requirements, relevant minimum balances, and payment timing. Use those disclosures to confirm every requirement before opening or funding the account.

- The direct-deposit, transaction, and holding requirements
- The earliest safe account-closing date
- The expected interest during the same period
- Any restriction that could disqualify you or trigger a clawback
