Ironbridge Online HYSA Review 2026: The Fine Print That Matters

Most online savings rates have flatlined this quarter. Ironbridge Online's 4.75% APY is one of the few that didn't. We pulled the account terms apart to see whether the headline holds up once you read the footnotes.

Where the rate breaks

Ironbridge Online's tier table looks simple but isn't. The 4.75% APY headline applies to balances under $250K. Above that, the rate steps down by 0.05 per tier. For most households this is moot. For households parking proceeds from a home sale, it's the difference between a 12-month plan and a 6-month plan. We surfaced the steps in the table further down.

What we'd watch

Ironbridge Online's rate has been at this level for six weeks. If the broader HYSA market drops below 4.50%, expect Ironbridge Online to follow within ten business days — that's been their pattern. We've added the account to our weekly Sunday pull so any change shows up on Monday morning's Rate Floor.

How we tested

We opened a soft-pull control account with Ironbridge Online on a Monday and tracked the posted APY against the published rate every day for two weeks. We also matched every fee disclosure against the application flow. The test account funded with $2,500 — small enough to test minimum-balance traps, large enough to avoid promo-rate caps. The 4.75% APY held every day of the pull period. The minimum-balance language said '$0' on the application, which was true.

Compared to our other top picks

Apex HYSA is currently 0.05 lower at 4.63, but Apex's transfer limits are double Ironbridge Online's. Vault Online is at the same headline but charges $5/month if balance drops below $1,000. Ironbridge Online has no minimum and no fee. For most households that math wins.

Funding speed and ACH

First ACH funded next-business-day. Outbound ACH limits are the standard $25K daily, $50K monthly. Wire-out fee is $20, which is in line with peers. Mobile check deposit limit was $10K, which is generous compared to the credit-union desks we tested.

What's next on the floor

Ironbridge Online's 4.75% APY stays on the high-yield savings watchlist for the next two weeks. We'll re-pull rates Sunday night and post any meaningful change in the next Weekly Rate Floor.
