Segment Reporting [Abstract]  
OPERATING SEGMENT INFORMATION OPERATING SEGMENT INFORMATION
We provide a wide range of banking products and related services, primarily in 11 western states: Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming. Our operations are organized principally through seven separately managed affiliate banks, each operating under its own local brand and management team: Zions Bank, CB&T, Amegy, NBAZ, NSB, Vectra, and TCBNW. These affiliate banks constitute our primary operating segments.
Our affiliate model emphasizes local authority and accountability, including locally informed pricing and product customization, to maximize customer satisfaction, strengthen community relationships, and improve profitability and shareholder returns.
At September 30, 2026, Zions Bank operated 92 branches in Utah, 25 branches in Idaho, and one branch in Wyoming. CB&T operated 77 branches in California. Amegy operated 76 branches in Texas. NBAZ operated 56 branches in Arizona. NSB operated 43 branches in Nevada. Vectra operated 33 branches in Colorado and one branch in New Mexico. TCBNW operated two branches in Washington and one branch in Oregon. During the first nine months of 2026, all of the Bank's assets and revenues were located in or derived from operations within the United States.
We focus on serving customers in the communities in which we operate. Each operating segment offers a wide range of banking products and related services, delivered digitally or through other traditional channels. These include commercial and small business banking, capital markets and investment banking, commercial real estate lending, retail banking, and wealth management.
The affiliate banks are supported by an enterprise-level segment—referred to as the “Other” segment—which provides governance and risk oversight, capital allocation, and strategic objectives, and includes centralized technology infrastructure, back-office operations, and certain business lines that are not managed through the affiliate structure.
Centrally provided services are allocated to the operating segments based on estimated or actual usage of those services. Capital is allocated according to the risk-weighted assets held by each segment. We utilize an internal funds transfer pricing (“FTP”) process to measure segment performance. This methodology is subject to ongoing refinement. Transactions between segments are generally conducted at fair value, with intercompany profits eliminated in consolidation. Total average loans and deposits for the segments include minor intercompany amounts and certain deposits with the “Other” segment.
We evaluate segment performance and allocate resources primarily based on income or loss from operations before income taxes. The accounting policies applied to the operating segments are consistent with those described in the Notes to Consolidated Financial Statements.
The chief operating decision maker (“CODM”) is our Chairman and Chief Executive Officer. The CODM regularly receives certain segment-level information, including net interest income, noninterest income, significant noninterest expenses, and income or loss from operations before income taxes. This information is used to evaluate performance and inform resource allocation decisions for each segment.
The following schedule presents selected operating segment information that is regularly provided to the CODM to evaluate performance and allocate resources for the three months ended September 30, 2026 and 2025:
