Client Overview
OCC is one of the world’s largest options clearinghouses, supporting 19 major U.S. exchanges and trading platforms. It processes massive daily volumes of options, futures, and securities lending trades, where speed, resilience, and regulatory compliance are mission-critical. As market volatility increased and regulatory expectations tightened, OCC set out to modernize its technology foundation to enable real-time insights, stronger resilience, and scalable growth.
Customer Challenge
Legacy systems and batch-driven processes struggled to keep pace with rising transaction volumes, real-time risk demands, and stringent recovery requirements. Manual workflows, slow calculations, and fragile disaster recovery mechanisms limited operational agility and increased risk exposure.
Key pain points included:
Legacy UI and manual workflows slowing reconciliations and processing
Complex hybrid infrastructure (AWS + QTS) with unclear ownership and documentation
Disaster recovery processes failing to meet RTO and RPO targets
Batch-based risk and margining calculations taking 8+ hours
Limited ability to respond in real time during periods of market volatility
What was at stake?
Without modernization, OCC faced heightened operational and systemic risk, potential regulatory non-compliance, slow response during market stress, and insufficient resilience to support its role as a critical financial market infrastructure.
Ness Solution
Ness partnered with OCC to deliver a cloud-first modernization spanning applications, infrastructure, data, and real-time processing. The transformation introduced a resilient, high-performance ecosystem capable of real-time clearing, risk, and margining.
Key elements included:
Migration of legacy transaction workflows to AWS
Kafka-based real-time streaming architecture
Flink-powered stream processing for risk and margining
Strengthened hybrid AWS + QTS infrastructure
Fully automated, auditable disaster recovery pipelines
Standardized APIs, CI/CD, and Infrastructure-as-Code
Engagement model
Ness engaged through a multi-year, phased transformation, working closely with OCC’s technology, operations, and risk teams. The approach balanced modernization with operational continuity, ensuring zero disruption to clearing activities while progressively strengthening resilience, performance, and compliance.
What Changed?
The result was a unified, real-time operational backbone built for scale, volatility, and regulatory scrutiny.
Business Outcomes
Strategic impact
OCC transitioned from batch-driven, resilience-constrained operations to a real-time, cloud-first clearing platform built for market volatility and regulatory rigor. Resilience became engineered, not reactive. Risk insight became immediate, not delayed. With a hardened hybrid foundation and real-time intelligence at its core, OCC is positioned to support future market growth, evolving regulations, and the next generation of clearing and risk management.
