When a payment system becomes important enough that its failure would disrupt others, the standards change. The PFMI — the principles for financial market infrastructures — set out what such infrastructure must meet across capital, liquidity, operational resilience and governance. A settlement hub may inherit those expectations long before it is formally designated.

What PFMI covers

The standards address four broad areas:

  • Capital — the resources to absorb losses and stay solvent through stress.
  • Liquidity — the ability to settle obligations when due, including under stress.
  • Operational resilience — the capacity to keep running and to recover.
  • Governance — clear accountability, risk management and disclosure.

These are not separate projects. They are properties of the architecture, and a weakness in one tends to show up as a weakness in another.

Why a settlement hub inherits them

SUPA's long-term aim is a hub that holds correspondent accounts for institutions rather than each institution opening accounts everywhere. Approved operations enter a single order book; offsetting flows cancel internally; the remainder is routed onward. Netting like this concentrates settlement and therefore concentrates the standards that apply to it. A hub whose netting is relied upon by many participants may come to be treated as systemically relevant.

The practical consequence

The choices that satisfy these standards are made years before a licence is granted. Internal settlement between participants, a single order book and a double-entry ledger are all decisions that bear on resilience and governance later. Designing for them early is not over-engineering; it is sequencing.

It also means the standards are not something a firm adopts at the moment of designation. They are properties the architecture either has or lacks, and rebuilding them afterwards is far harder than building them in. For a hub that expects to be relied upon by many participants, that is the whole point.

In short

  • PFMI addresses capital, liquidity, operational resilience and governance.
  • A settlement hub inherits systemic expectations by design.
  • Netting concentrates settlement and raises the bar.
  • Resilience and governance are architectural choices, made early.
