Tideline Bank HYSA Review 2025: The Fine Print That Matters

Tideline Bank kept showing up at the top of our weekly HYSA pull, so we ran a full review against the rate we use as our control across every household-savings desk on the floor.

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.

Compared to our other top picks

Apex HYSA is currently 0.05 lower at 4.27, but Apex's transfer limits are double Tideline Bank's. Vault Online is at the same headline but charges $5/month if balance drops below $1,000. Tideline Bank has no minimum and no fee. For most households that math wins.

Where the rate breaks

Tideline Bank's tier table looks simple but isn't. The 4.41% 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

Tideline Bank's rate has been at this level for six weeks. If the broader HYSA market drops below 4.50%, expect Tideline Bank 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.

What's next on the floor

Tideline Bank's 4.41% 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.
