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 Arizona 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. Arizona 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 Arizona 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.
Desert Financial is open to anyone who lives, works, or attends school in Arizona — no specific employer group required. Geographic eligibility covers the entire state, making it accessible to all Arizona residents. Membership requires a $5 savings deposit.
Does Arizona tax savings-account interest?
Yes. Arizona has a flat 2.5% state income tax that applies to interest income — one of the lowest rates in the country. A 4.65% HYSA nets roughly 2.86% after combined federal and AZ state tax for a top-bracket earner, making Arizona one of the most tax-efficient states for deposit accounts after the zero-tax states.
Why are Arizona deposit rates rising faster than the national average?
Arizona's rapid population growth (Phoenix is consistently a top-3 growth metro) means local banks and credit unions are competing intensely for new deposits. Desert Financial, OneAZ, and Arizona Federal have all raised savings and CD rates aggressively to capture relocating consumers, many of whom arrive with significant cash from home sales in higher-cost states.
Are Arizona state-chartered deposits federally insured?
Yes. All Arizona state-chartered banks carry FDIC insurance and credit unions carry NCUA insurance, both up to $250,000 per depositor per ownership category. The Arizona Department of Financial Institutions supervises state-chartered institutions.
