Post-Trade Moderization: Tier-1 Bank’s Platform Transformation

In today’s capital markets, Tier-1 banks are undertaking ambitious technology overhauls in their post-trade environments driven by modern needs and regulatory changes in recent times. A prime example is the migration from a long-established legacy back-office systems to a next-generation capital markets solution. This transition isn’t just a software upgrade; it’s a comprehensive transformation aimed at boosting efficiency, scalability, and compliance. Below, we break down the technical and business differences between these platform types, and explore how Zinkworks is helping deliver tangible change for a leading US investment bank.

Legacy Post-Trade Platforms: Dependable but Constrained

These platforms, often deployed on mainframe architectures, have long served as the operational backbone for exchange-traded derivatives and other cleared instruments. Their technical features include:

Multi-asset global coverage on a single system.
Batch-based processing built for overnight runs.
Hundreds of standard reports and accounting integrations.

From a business standpoint, they allowed firms to consolidate global clearing on one platform and improve control. But over time, their limitations became more pressing:

Inability to support real-time processing.
High cost of ownership (proprietary tech, niche skills).
Manual workflows and fragmented integration with modern systems.

Zinkworks’ Role in a Tier-1 Bank’s Post-Trade Migration

Zinkworks is currently supporting a Tier-1 US bank in one of the industry’s most ambitious post-trade modernization programs. The multi-year effort is focused on migrating from a legacy post-trade system to a real-time, next-generation platform. Zinkworks’ role includes:

01 Re-engineering and Automating Workflows

Redesigning key operational flows to eliminate manual tasks.
Increasing straight-through processing to reduce error rates and speed up end-of-day activities.
Complete modernization of workflows to enable loosely coupled systems to allow for future proof architecture.

02 Real-Time Data Integration

03 Enhancing Clearing and Settlement Processes

04 Compliance and Future-Readiness

05 Driving Operating Model Transformation

Why it Matters

This ongoing migration is more than a system replacement. It’s a fundamental redesign of how the bank handles its most critical clearing and settlement functions. The transformation is already delivering:

Faster, cleaner processing across the trade lifecycle.
Enhanced risk and regulatory posture.
A scalable foundation for future growth and innovation.

Zinkworks brings a unique combination of deep capital markets knowledge and modern engineering skills to support initiatives like this. Our work demonstrates that the right approach to post-trade modernization doesn’t just meet today’s needs—it creates lasting strategic advantage.
