Fresh from Sibos in Miami, this month’s Word on the Streets explores some of the forces reshaping financial services, from AI and cybersecurity to tokenization, quantum computing and the global race towards T+1 settlement. Across these conversations, one theme stands out: innovation is moving quickly, but turning emerging technology into trusted, resilient and commercially viable infrastructure remains the real challenge. We’ve pulled together our perspectives and observations from the event, alongside the developments we believe deserve your attention.
Closer to home, AI is changing not just how we search, but how businesses are discovered, evaluated and recommended. Being visible on Google is no longer enough if AI doesn’t recognise your brand as a credible authority worth referencing. At Streets Consulting, we’ve developed a proprietary GEO Discoverability tool to assess how your brand is positioned for this new reality, identify gaps and help calibrate your content, communications and digital presence accordingly. Curious how AI sees your business? Download our free GEO Discoverability Playbook conduct your own mini-audit, or reach out to me directly and we’ll put your brand to the test with your own Discoverability Score. You might be surprised by what AI knows about you, or what it doesn’t.
Kind regards,
Ian Stirling, CEO
Financial institutions must shift from viewing cybersecurity as an operational cost to building it as vital, strategic business infrastructure. As compromised identity credentials saturate dark-web marketplaces, firms must redefine digital trust, dismantle internal departmental silos, operationalise threat intelligence, and deploy defensive AI to detect, disrupt and contain attacks before monetisation occurs.
The global transition toward a T+1 settlement cycle exposes complex operational misalignments across foreign exchange, fund settlement, and multi-jurisdiction rules. To manage compressed post-trade timelines and mitigate friction, institutions must move beyond temporary workarounds, implement permanent end-to-end automation, and harmonise market conventions to ensure long-term efficiency and resilience.
Quantum computing poses an existential threat to financial infrastructure, rendering legacy public-key encryption vulnerable to disruption. While post-quantum cryptographic standards are available, institutional inertia remains the primary bottleneck. Banks must embrace cryptographic agility to future-proof defences before the arrival of quantum.
The most interesting question emerging from Sibos is not “What can AI do?”, but “How resilient is our financial system for whatever comes next?”. Safely modernising post-trade infrastructure requires a hybrid-by-design model, balancing digital innovation with the scale, central netting, legal certainty, and institutional trust essential to global markets.
Data governance, distributed architectures, and applied AI are transforming cross-border commerce. By shifting away from centralised repositories, automating credit reviews, and establishing verifiable identities for autonomous agents, digital trade infrastructure is streamlining supply chains, expanding liquidity, and helping to close the $2.5 trillion global trade finance gap.
Modernising post-trade infrastructure requires a hybrid-by-design model that bridges traditional and digital ecosystems. By preserving central netting, optimising collateral efficiency, and establishing pragmatic cross-rail interoperability, market infrastructures can safely deploy converging technologies without compromising the scale, legal certainty, and regulatory trust essential to institutional markets.
As financial assets transition to tokenized networks and shared ledgers, trust is being redistributed across code, legal frameworks, and human accountability. Establishing institutional trust requires combining enforceable legal rights, robust smart contract governance, and central bank settlement anchors, balancing efficiency with intentional friction to safeguard global transactions.
As global securities markets transition toward ISO 20022, financial market infrastructures face a pivotal operational crossroads. Balancing competing priorities like T+1, resilience, and tokenization, institutions must establish a common data model and move away from disruptive “Big Bang” migrations toward a flexible, long-term sunset approach that enables seamless cross-rail interoperability.
