Best Banks & Credit Unions in Arizona

Compare the best banks and credit unions in Arizona — up to 3.80% APY, verified fees, minimums, and membership rules from 32+ local institutions.

Arizona banking is shaped by rapid population growth — the Phoenix metro is one of the fastest-growing in the country, which has attracted both national banks and strong local credit unions competing aggressively for new deposits. Desert Financial CU, Arizona's largest credit union, serves anyone who lives or works in the state, and OneAZ CU provides statewide access with competitive yields. State-chartered institutions answer to the Arizona Department of Financial Institutions, and all carry FDIC or NCUA insurance to $250,000.

Every bank with a branch in Arizona

57 FDIC-insured banks run 945 full-service offices in Arizona. 19 of them are community banks, and 7 operate nowhere else. This is the federal record: every figure below is the regulator's own.

Deposits by office come from the FDIC Summary of Deposits, counted each 30 June; the leverage ratio is capital as a share of assets, from each bank's latest Call Report. Nothing here is blended into a score. Search by ZIP to see the offices nearest you.

Every credit union with an office in Arizona

56 federally insured credit unions run 336 offices in Arizona, between them serving 23,500,329 members. 35 carry the NCUA's low-income designation. Figures are from each credit union's own NCUA Call Report.

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.

Arizona banking FAQ — credit unions, rates & insurance

Who can join Desert Financial Credit Union?

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.
