The companies said the test was limited to technical verification and did not represent a commercial launch or live customer offering.
Banks experiment with AI-agent payments
HSBC is among several banks testing how AI agents could initiate financial transactions on customers’ behalf.
In March, Spanish banking giant Santander completed an AI-agent-initiated payment using Mastercard’s Agent Pay infrastructure in a controlled test involving the bank’s live payment systems.
Swiss digital asset bank Sygnum followed in May with a test of AI-agent-driven transactions on a blockchain mainnet, with customers required to approve and sign each transaction. Spanish banking group CaixaBank also completed an AI-agent-initiated card transaction using Visa Intelligent Commerce and existing merchant payment systems.
However, not everyone believes established banks can adapt their existing infrastructure to AI-driven finance. In a May interview with Cointelegraph, Augustus Bank CEO Ferdinand Dabitz argued that traditional clearing banks rely on decades-old systems designed for human operations rather than automated, around-the-clock transactions.
Augustus is developing a US bank built around stablecoins and AI-driven operations, betting that purpose-built infrastructure can replace parts of traditional banking systems.
AI agents could drive blockchain adoption
Investment research firm Citrini Research recently explored blockchain’s potential role in AI-driven commerce. In an Oct. 8 report titled Breaking The Wall, the firm argued that autonomous AI agents could increase demand for programmable financial infrastructure.
The firm said traditional financial systems, designed primarily for human users, may need to adapt as AI agents increasingly handle transactions across applications. It argued that blockchain networks could provide the always-on infrastructure needed to move money and financial assets programmatically.
“AI agents move programmatically, 24/7, across applications, and it’s only logical that money and financial assets eventually will, too,” Citrini wrote.
