The system boundary of T2 defines which responsibilities belong to T2 and which belong to its environment. I use this boundary to separate the T2 core from connected TARGET Services and shared infrastructure. T2 combines Central Liquidity Management (CLM) and Real-Time Gross Settlement (RTGS). Other services exchange liquidity, data, or settlement instructions with T2, but that does not make them part of T2. A clear boundary therefore keeps requirements, interfaces, ownership, and testing precise.

When I analyse T2 in TARGET Services, I do not treat it as an isolated payment system. I place it inside the wider Eurosystem infrastructure for payments, securities, instant payments, and collateral. This context matters because many important T2 requirements arise at service boundaries. Liquidity moves between systems. Collateral affects credit. Settlement depends on connected services. Therefore, I first define the landscape, responsibilities, and interfaces before I analyse individual T2 functions.

When I analyse T2, I start with its purpose. T2 Objectives explain why the Eurosystem operates this infrastructure and which outcomes its design must support. T2 is more than a platform for large-value payments. It links settlement in central bank money with monetary policy, financial stability, and efficient liquidity management. Therefore, I use these objectives as the basis for understanding its core capabilities, quality requirements, interfaces, and operational rules across TARGET Services.

When I analyse T2 within TARGET Services, I start with its role in the Eurosystem. T2 is the core service for settling large-value and other time-critical payments in central bank money. It connects payment settlement with central liquidity management and supports monetary policy operations, interbank transfers, and commercial payments. Therefore, understanding T2 means understanding how the Eurosystem moves liquidity safely, finally, and efficiently across its financial market infrastructure.

TARGET Services T2 – System Analysis Article Series Part 1: Strategic & Business Context Article 3 When I analyse payment infrastructures, I start with T2 Stakeholders. T2 sits at the heart of the euro payment system. Therefore, many parties depend on it, shape it, or govern it. In this article, I identify the key stakeholder
