ONB Bank & Trust Company operates as a locally owned, mid-sized commercial and retail bank headquartered in Tulsa with a significant branch presence throughout Oklahoma, including multiple locations across Oklahoma City's metro area. Its institutional identity centers on relationship banking and business lending rather than the standardized digital-first model of large national competitors.
Founded in 1908, ONB serves individuals, families, and small to mid-sized businesses primarily across central and northeastern Oklahoma. The bank operates roughly 50 branches statewide, with Oklahoma City locations clustered in the downtown core, Midtown, and surrounding neighborhoods. Unlike Wells Fargo or Bank of America, ONB maintains decision-making locally, meaning loan approvals and account issue resolution often bypass regional call centers. The bank competes directly with community banks like First National Bank & Trust (also Oklahoma-based) and regional players like Arvest Bank, while occupying middle ground between local credit unions and national chains.
ONB offers standard checking and savings accounts, money market accounts, and certificates of deposit. Checking accounts carry no monthly fees if customers maintain a $500 minimum balance; those without the minimum pay $8 monthly. The savings account carries a comparable $500 minimum with no fee or $5 monthly otherwise. Interest rates on savings and money market products fluctuate; verify current rates directly with ONB, as federal rate changes affect yields monthly.
Business checking starts at no monthly fee with a $1,000 balance requirement. Small business lending, the bank's signature strength, includes lines of credit and term loans where approval timelines typically run one to two weeks rather than the five to ten days common at larger institutions. This speed matters for seasonal businesses or rapid-growth scenarios. ONB also offers merchant services, payroll processing, and cash management for established businesses.
Wealth management services through ONB Trust Company include investment advisory, trust administration, and estate planning consultation. Fee structures for trust accounts begin around $1,500 annually for accounts under $250,000 and scale upward; speak with a trust officer for personalized pricing.
First National Bank & Trust (headquartered in Oklahoma City) operates 20+ locations in the metro area and emphasizes personal relationships similarly to ONB, though with slightly broader statewide reach (70+ branches). First National often matches or beats ONB on checking account minimums and has a more developed mobile app, a factor for customers who prioritize digital convenience.
Bank of Oklahoma (BOK Financial, Tulsa-based) runs 40+ Oklahoma City-area branches and competes heavily on business lending. BOK branches open earlier (some at 7:30 a.m. vs. ONB's typical 9 a.m.) and maintain more evening hours in high-traffic neighborhoods. For customers who need predictable extended hours, BOK's schedule has an edge.
Credit unions like Tinker Federal Credit Union (federal employees and their families) charge zero monthly fees across checking and savings but require membership eligibility. If you qualify, a credit union typically costs less; if not, ONB's $500 minimum sitting fee is moderate for Oklahoma City.
Choose ONB if you prioritize small business lending speed and want a bank where loan officers know local market conditions. Choose First National Bank & Trust if you want comparable relationship banking with slightly better digital tools. Choose BOK if extended branch hours or earlier opening times matter to your weekly routine.
ONB works well for small business owners, established families with modest wealth, and customers who value face-to-face problem-solving. The trust division attracts rural landowners and business owners building estate plans. Retail account holders who rarely visit a branch or depend entirely on mobile banking will find ONB adequate but not innovative; app functionality lags slightly behind Chase or Bank of America.
High-net-worth individuals seeking investment management should compare ONB Trust offerings against larger regional wealth managers like Merrill Lynch or Edward Jones offices in Oklahoma City, where investment expertise often exceeds what a community bank trust department can offer.
Visit an ONB branch with a government-issued ID and a current address. Account opening takes 15 to 20 minutes for checking or savings. The bank does not require an opening deposit, though the $500 minimum applies immediately to avoid monthly fees. Loan inquiries (business or personal) begin with a conversation and a loan officer's assessment of income, credit, and collateral; applications follow if both parties proceed. Allow one to two days for initial underwriting.
Most Oklahoma City ONB branches operate Monday through Friday, 9 a.m. to 5 p.m., with Saturday hours (typically 10 a.m. to 2 p.m.) at high-traffic locations. Verify specific branch hours via ONB's website or call ahead, as some locations adjust seasonally. Downtown branches offer street parking and nearby paid lots; suburban locations provide free on-site parking. All locations remain closed Sundays and federal holidays.
ONB's network of ATMs spans Oklahoma; out-of-network ATM fees are $2 per transaction.
ONB's longevity in Oklahoma and established relationships with local businesses make it a logical choice for entrepreneurs and families who plan to stay in the region and benefit from personal banking continuity.
