Weekly Fintech Brief — AI Agents, Stablecoins and Tokenised Money Move from Experiment to Infrastructure

AI Agents, Stablecoins and Tokenised Money Move from Experiment to Infrastructure

Week ending 13 September 2026

The past week marked a significant shift in fintech: AI agents are moving closer to real payment execution, stablecoins are becoming part of institutional payment infrastructure, and banks are increasingly pursuing direct control over digital-asset and payment capabilities.

1. Top Headlines

1. Ant, Visa and Mastercard develop a “Know-Your-Agent” framework — Finextra

Ant International, Visa and Mastercard are working on a common Know-Your-Agent (KYA) framework covering agent identification, onboarding, accountability and risk management.

5. US Bank completes live USBDC stablecoin pilot — FinTech Futures

US Bank completed a live cross-border transaction using its proprietary dollar-backed USBDC stablecoin on the Stellar blockchain.

6. Consumer trust in agentic payments remains low — Finextra

Visa research found that 72% of US consumers have used an AI assistant, but only 23% trust generative AI to handle payment transactions on their behalf. The gap highlights a central challenge for agentic commerce: payment infrastructure must establish identity, authorization, security and accountability before consumers will allow AI to move money autonomously.

7. Block applies for US national trust bank charter — FinTech Futures

Block submitted an application to the OCC to establish Builders Bank & Trust, an uninsured national trust bank focused on custody and fiduciary services, including Bitcoin and stablecoins. The move reflects a broader trend of fintechs seeking more direct regulatory and infrastructure control over financial products. Read the original FinTech Futures article

8. Chime strikes $590m deal for Stride Bank — FinTech Futures

Chime agreed to acquire Stride Bank, its banking partner of seven years, for $590 million in cash. The transaction illustrates how mature fintechs are increasingly bringing banking infrastructure in-house to gain greater control over products, compliance and economics.

9. Visa and Revolut complete passkey-based agentic payment — Finextra

Visa and Revolut conducted what Finextra reports as the first passkey-authenticated agentic card payment in France. The combination of passkeys, AI agents and card-network controls points toward a future in which authentication can happen without exposing traditional payment credentials to autonomous software.

2. In-Depth Highlight: The Rise of “Know-Your-Agent” Payments

The most strategically important development this week may be the collaboration between Ant International, Visa and Mastercard to develop a common Know-Your-Agent framework. The objective is to create an interoperable way to identify, onboard and manage AI agents that participate in financial transactions.

This matters because agentic commerce creates a fundamentally different payment problem. Traditional payments authenticate a person, device or merchant; agentic payments introduce software that may search, negotiate, select products and ultimately initiate a transaction on behalf of a person or business.

The proposed KYA approach could therefore become analogous to KYC for machines: establishing who an agent is, who authorized it, what it is permitted to do and who is accountable when something goes wrong. The initiative is particularly significant for Singapore because the work is being conducted through BuildFin.ai, convened by the Monetary Authority of Singapore.

The economic opportunity is substantial. The participating organizations cite projections that AI agents could orchestrate $3 trillion–$5 trillion of global consumer commerce by 2030. But the Visa Trust Index simultaneously shows that only 23% of US consumers currently trust GenAI to execute payments, demonstrating that infrastructure and governance will have to develop alongside the technology.

Executive takeaway: agentic commerce is no longer primarily an AI-model problem. It is becoming an identity, authorization, risk, payments and governance problem.

3. Market & Industry Insight

AI is moving from interface to transaction layer

The fintech industry is moving rapidly from AI copilots that answer questions toward AI agents that can actually execute financial workflows. Visa/Revolut’s passkey transaction, Ant/Visa/Mastercard’s KYA initiative and Mastercard’s AI-commerce infrastructure all point in the same direction: the payment agent itself is becoming a participant in the transaction.

The critical differentiator will therefore be trust infrastructure. Agent identity, transaction limits, delegated authority, fraud monitoring, auditability and human escalation will become as important as the underlying AI model.

Stablecoins are becoming payment infrastructure

Stablecoin activity is also becoming increasingly institutional. US Bank has tested its own stablecoin, while Circle is acquiring Tazapay and Singapore’s DBS, OCBC and UOB have executed tokenised SGD transactions through Swift’s blockchain ledger.

The strategic direction is increasingly clear: tokenised deposits, stablecoins and blockchain settlement are converging with conventional banking infrastructure rather than existing purely as alternative crypto rails.

For banks and payment companies, the question is shifting from “Should we experiment with stablecoins?” to “Where can programmable digital money improve settlement, liquidity and cross-border payments?”

4. Company & Startup Spotlight

Circle / Tazapay

Circle is the issuer of USDC and is building infrastructure around stablecoin-based financial services. Its planned $400 million acquisition of Tazapay gives it additional cross-border payment infrastructure, local payout connectivity across more than 100 markets and significant APAC exposure.

Why it matters: Circle is moving beyond stablecoin issuance toward controlling more of the end-to-end payment stack. The acquisition could accelerate USDC’s use in B2B and cross-border commerce.

Mastercard

Mastercard’s Wallet Pay initiative targets interoperability across wallets, cards, QR, NFC and online payments. The company says the program can connect more than 3.7 billion Mastercard credentials to digital wallets.

Why it matters: rather than competing directly with every wallet, Mastercard is increasingly positioning itself as the interoperability layer connecting fragmented payment ecosystems.

5. Regulatory & Policy Watch

US banking infrastructure: Block’s OCC national trust bank application highlights the growing convergence between fintech, crypto custody and regulated banking infrastructure.
Singapore / AI payments: MAS-convened BuildFin.ai is being used to develop common approaches for AI-agent verification, accountability and risk management. This could become strategically important as agentic payments scale.
Australia card payments: AusPayNet, Visa and Mastercard have established guidance ahead of Australia’s new no-surcharge rules for card payments, scheduled to take effect 1 October 2026.

6. Quote of the Week

“Trust will be foundational to driving agentic commerce adoption.”

— Oliver Jenkyn, Group President, Visa, discussing consumer confidence in AI-powered payments.

The quote captures the industry’s biggest challenge: AI can already execute increasingly sophisticated tasks, but financial services require customers to trust the system with money.

7. What’s Next

15 September: Finextra webinar — Are banks actually ready for digital money? focusing on stablecoins, tokenised deposits and CBDCs.
16 September: Finextra webinar on embedded accounting for mid-corporate businesses, open banking and multi-bank treasury management.
17 September: Finextra webinar on the future of consumer payments, including cards, Pay by Bank and multi-rail payments.
18 September: PayTech Awards USA nominations deadline.

Bottom Line

The defining fintech story this week is convergence.

AI agents are becoming payment participants. Stablecoins are becoming institutional settlement tools. Tokenised deposits are entering live banking infrastructure. Meanwhile, fintechs such as Chime and Block are moving closer to regulated banking infrastructure.

The next phase of fintech competition will therefore not be determined solely by who has the best app or AI model. It will increasingly be determined by who controls identity, trust, liquidity, compliance and transaction infrastructure.
