Case Study: Health Care Service Corporation reduces idle working capital from $4B to $25M with Kyriba

How Treasury’s Data Transformation at HCSC Reduced Working Capital from $4B to $25M

Health Care Service Corporation (HCSC), the fifth-largest U.S. health insurer ($64B revenue, 24,000 employees), charged its 60-person treasury team with becoming a strategic partner to the CFO and Board. The team faced siloed systems and limited real-time visibility, leaving roughly $4.0B of Tier 1 idle cash and constraining its ability to deliver timely BI, unlock liquidity, and guide enterprise financial decisions.

Over a three-year program HCSC centralized treasury technology and data—building on Kyriba’s TMS and deploying an in‑house TEAR data warehouse, API integrations, and BI/visualization—to unify reporting and automate processes. The initiative delivered 100% enterprise cash visibility, cut idle cash from $4.0B to $25M, unlocked $9B of investable capital (significantly boosting investment income), repurposed staff into strategic roles, improved crisis responsiveness, and directly added over $320M of value.
