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.

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.
