# Which large banks use Temenos? Source: https://www.bankingnewsai.com/banks/leaders/use-temenos Last updated: Oct 30, 2026 Checked 2026-10-28 · bank profiles and the Temenos vendor page. Nothing on this page is written by a model: every row is computed from that dataset. On the public record as of Oct 28, 2026, 3 of the 141 large banks profiled have a dated, sourced profile entry naming Temenos (a use case, a timeline move, a platform note or a vendor-page customer record). Ranked by entries naming Temenos, the top 3 are Commerce (7 entries), Regions (4 entries) and Western Alliance (2 entries). Commerce's strongest evidence: Temenos core, origination and payments platform (use case, in production, May 15, 2024). ## Which of the large banks use Temenos? | # | Bank | Entries naming Temenos | Strongest entry | Status | Date | On this site | Sources | | --- | --- | --- | --- | --- | --- | --- | --- | | 1 | [Commerce](https://www.bankingnewsai.com/banks/commerce) | 7 | Temenos core, origination and payments platform (use case, in production, May 15, 2024) | In production | May 15, 2024 | [Commerce profile](https://www.bankingnewsai.com/banks/commerce#where) | [Temenos](https://temenos.com/news/2024/02/20/top-us-bank-commerce-goes-live-with-loan-origination-on-temenos-banking-platform); [Temenos](https://temenos.com/press_release/top-us-bank-commerce-bank-goes-live-on-the-fednow-service-with-temenos) | | 2 | [Regions](https://www.bankingnewsai.com/banks/regions) | 4 | Temenos (section, Oct 6, 2026) | Mentioned | Oct 6, 2026 | [Regions profile](https://www.bankingnewsai.com/banks/regions#patents-and-partners) | [ABA Banking Journal](https://bankingjournal.aba.com/2026/10/progressive-modernization-for-cores); [Regions Financial (SEC filing)](https://www.sec.gov/Archives/edgar/data/1281761/000128176126000057/a3q26investormeetingmate.htm) | | 3 | [Western Alliance](https://www.bankingnewsai.com/banks/western-alliance) | 2 | Temenos customer spotlight (move, May 28, 2025) | Mentioned | May 28, 2025 | [Western Alliance profile](https://www.bankingnewsai.com/banks/western-alliance#timeline) | [Temenos](https://www.temenos.com/wp-content/uploads/2025/05/NAM_TRF_2025_Agenda.pdf) | ## How is this ranked? Data: the 141 bank profiles on this site (lib/banks), every entry dated and sourced, plus the bank customers listed on the Temenos vendor page (/vendors/temenos). Rule: A bank is listed when at least one use case, timeline move, platform note, section row, number, quote or leader entry on its profile matches the pattern Temenos, or when the vendor page records it as a customer. Score = number of matching entries. Order: entries, then banks with a matching use case in production, then the newest entry. An entry that only restricts or blocks the vendor's tool is kept, marked "Restricted" and sorted last. Counts: 3 of 141 profiled banks qualify; 5 distinct sources cited in the table. Data checked 2026-10-28; ranking template updated 2026-10-30. ## What are the caveats? Naming Temenos on the public record is evidence of a relationship, a pilot or a policy, not of contract size or exclusivity; many banks use several providers and do not name them all. Banks absent from the table have nothing matching on the record this site holds, which is not evidence that they do nothing. Each row links the bank's own page, where every entry carries its sources. ## FAQ ### Which bank ranks first? Commerce Bancshares leads with 7 entries: Temenos core, origination and payments platform (use case, in production, May 15, 2024). Regions is second with 4. ### How many large banks name Temenos in sourced AI records? 3 of the 141 profiled banks (120 US, 21 non-US groups). Among those listed, 3 are US banks and 0 non-US groups. ### What counts, and what does not? A bank is listed when at least one use case, timeline move, platform note, section row, number, quote or leader entry on its profile matches the pattern Temenos, or when the vendor page records it as a customer. Score = number of matching entries. Order: entries, then banks with a matching use case in production, then the newest entry. An entry that only restricts or blocks the vendor's tool is kept, marked "Restricted" and sorted last. Source: the 141 bank profiles on this site (lib/banks), every entry dated and sourced, plus the bank customers listed on the Temenos vendor page (/vendors/temenos). ### Is this a measure of capability? No. Every row is a sourced fact on the public record: what the bank, a regulator, a filing or an independent outlet has put on the record. The page does not rate how well anything works. ### When was this checked, and how often does it update? The data behind the table was last checked on 2026-10-28 (bank profiles and the Temenos vendor page). The page recomputes whenever that dataset changes and is republished with the site; it is never edited by hand. ## Related questions - [Which large banks use OpenAI?](https://www.bankingnewsai.com/banks/leaders/use-openai) - [Which large banks use Anthropic?](https://www.bankingnewsai.com/banks/leaders/use-anthropic) - [Which large banks use Microsoft?](https://www.bankingnewsai.com/banks/leaders/use-microsoft) - [Which large banks use Google Cloud?](https://www.bankingnewsai.com/banks/leaders/use-google-cloud) - [Which large banks use AWS?](https://www.bankingnewsai.com/banks/leaders/use-aws) - [Which large banks use several AI model providers?](https://www.bankingnewsai.com/banks/leaders/multiple-ai-model-providers) - [Which large banks have built proprietary AI platforms?](https://www.bankingnewsai.com/banks/leaders/proprietary-ai-platforms) - [Which large banks use Azure OpenAI?](https://www.bankingnewsai.com/banks/leaders/use-azure-openai) - [All ranked answers](https://www.bankingnewsai.com/banks/leaders) --- Canonical page: https://www.bankingnewsai.com/banks/leaders/use-temenos Part of [BankingNewsAI](https://www.bankingnewsai.com/) — a free daily brief on AI in banking, an AI regulation tracker (45 authorities, 260 documents) and AI-strategy profiles of the 120 largest US banks.
