A credit union is measured differently from a bank and the numbers are not interchangeable: the net worth ratio here is the NCUA's capital measure under 12 CFR 702, where 7% is well capitalised, and shares are the credit union equivalent of deposits. Membership usually turns on where you live or work, so a local credit union is often open to you even when its name suggests otherwise.
What makes a Iowa bank account worth opening
Look at four things in order: the APY (does it beat the FDIC national average of about 0.60%?), the monthly fee (anything above $0 should come with a clear waiver path), the minimum opening deposit, and the membership rule for credit unions. Iowa residents typically qualify for at least one large state-chartered credit union on residency alone, and that credit union is often the highest-APY option available locally.
Is my money safe at a Iowa bank or credit union?
Yes, if the institution is federally insured. FDIC covers banks up to $250,000 per depositor, per ownership category; NCUA covers credit unions at the same limits. Every institution in this directory carries one of those insurances — the FDIC or NCUA ID is listed on the full provider row.
Rates and fees change frequently. Confirm current figures directly with each institution before applying, and see our editorial methodology for how this directory is built and maintained.
