High-yield savings in Illinois.
Who regulates the banks and credit unions here, how your deposits are protected, and what to compare before you choose. We're not a bank and we open nothing — this is the context laid out in plain English. The rate itself is set nationally by each institution, not by Illinois.
The Illinois savings landscape
Illinois has one of the most competitive banking markets in the Midwest, anchored by Chicago's financial hub. Alliant Credit Union (one of the largest online credit unions in the US) is headquartered in Chicago and serves members nationally. Illinois savers also have access to major national banks, regional banks, and online-only HYSAs.
Who regulates it
Illinois Department of Financial and Professional Regulation
Supervises state-chartered banks, credit unions, and financial professionals in Illinois.
How your deposits are protected
FDIC (banks) · NCUA (credit unions)
Deposit insurance is federal and uniform in every state: up to $250,000 per depositor, per insured institution, per ownership category — from the FDIC for banks and the NCUA for credit unions. It comes from the institution, not from ClearValue Banking. Confirm a bank's status with FDIC BankFind before you move money.
What to focus on in Illinois
Illinois savers benefit from Alliant Credit Union's national reach — it's an online credit union based in Chicago that consistently ranks among the most competitive for savings rates. Membership is open broadly.
One thing that isn't local
The APY. High-yield savings rates are set nationally by each institution, so a top online bank pays the same in Illinois as anywhere else — which is why you won't find a Illinois-specific rate here. For how to read an APY, weigh the fees and minimums, and spot the catch, start with the high-yield savings guide.
Next step
See how your savings options compare.
We don't open accounts or hold your money. We lay out the account types and the tradeoffs against a published standard — real yield, fees, minimums, access — so you can decide with the fine print in plain sight, then take it to the bank or credit union that holds the account.

Educational only — not a bank. ClearValue Banking is an independent education and comparison publisher, not a bank, credit union, or FDIC/NCUA-insured institution. We do not open accounts, hold deposits, or provide personalized financial advice. Any account is opened with and held by the partner bank — the FDIC-insured institution; deposit insurance is provided by that bank (or, for a credit union, the NCUA), not by us. Rates, terms, and eligibility are set solely by the institution.
