Build vs Buy — Banking and Capital Markets

Weigh SaaS subscriptions against a custom build for Banking and Capital Markets — see the multi-year total cost of ownership and which path wins.

What this means for Banking and Capital Markets

  • The core banking system is a 30-year-old COBOL platform — every new product requires a six-quarter project, and the vendor's modernization roadmap keeps slipping while pricing keeps climbing.
  • KYC and AML onboarding takes 8-15 business days for commercial clients because operations is keying the same data into four systems and waiting on three queues of human review.
  • Trading desk technology is a Frankenstein of vendor platforms, internal Excel-VBA tools, and tactical Python scripts — every regulatory change forces a six-month remediation across all of them.

Where it pays to act

  • Document intelligence on commercial loan packages, ISDA agreements, KYC files, and trade confirmations — first-draft extraction with the analyst as reviewer, not data-entry clerk.
  • AML alert triage and case narrative drafting — LLM-assisted summarization of transaction patterns, counterparty data, and prior cases so investigators close more alerts per day.
