The future of payments is being shaped by powerful, underlying shifts — and two of the most impactful are the global ISO 20022 migration and the development of One-Leg Out (OCT Inst) Instant Payment schemes.

In this second video we dive into both topics with clarity, diagrams, and expert insight — showing not just what is changing, but why it matters and how professionals can prepare.

ISO 20022: A Common Language for Global Payments

The first half of the video explores ISO 20022 and the CBPR+ migration led by SWIFT and explains what’s really at stake:

• Why over 70 countries and major infrastructures (like T2, Lynx, SEPA, FedNow) are aligning on the 2019 ISO 20022 message versions
• What payment professionals should focus on to get up to speed — including concrete guidance on how to find and study key messages like pacs.008 and pacs.009
• The strategic implications of message harmonization across schemes, and how this shared foundation can streamline communication and integration

Rather than just a compliance challenge, ISO 20022 is presented as an opportunity to build stronger systems — and stronger careers.

One-Leg Out (OCT Inst): The Next Frontier of Instant Payments

The second half focuses on a newer, yet crucial, development: the OCT Inst scheme.

We unpack this complex topic with real-world examples and practical breakdowns, helping viewers understand:

• What One-Leg Out transfers are, and how they differ from traditional SEPA or cross-border flows
• How currency conversion and correspondent banking relationships operate in these models
• Why OCT Inst could be a game-changer for global instant payments, and what banks, PSPs, and regulators need to get right

As with ISO 20022, the goal is not just to inform — but to equip. If you’re dealing with SEPA, cross-border, or real-time payment implementations, these are essential frameworks to understand.
