HSBC settles AI agents' micropayments in tokenized deposits in a testnet trial with Ant Digital

The control sits with the bank. Crypto Briefing reported that the risk checks ran through an interface on HSBC's side ^[5], while Ant's network handled service access and coordinated payment ^[3]. According to the same outlet, the Tokenised Deposit Service records corporate deposits 1:1 as on-chain entries without introducing new public tokens ^[9]. HSBC put the agents on a deposit product it already offers and issued no coin to do it ^[9].

Cointelegraph names four banks testing agent payments, and HSBC is the only one of them paying in tokenized deposits ^[20]. Santander's March test ran over Mastercard's Agent Pay on the bank's live payment systems ^[13]. CaixaBank used Visa Intelligent Commerce and existing merchant systems ^[15]. Sygnum took agent transactions to a blockchain mainnet in May and required customers to approve and sign each one ^[14].

The case for stablecoins comes from a challenger. Augustus Bank is building a US bank around stablecoins and AI-driven operations ^[17]. Its chief executive, Ferdinand Dabitz, argued in a May interview with Cointelegraph that traditional clearing banks rely on decades-old systems designed for human operations ^[16]. Executives from HSBC and Ant, including Lewis Sun and Zhuoqun Bian, backed continued exploration of on-chain AI agents within a regulated setting, Crypto Briefing reported ^[19].

On this evidence agent payments end up settling in one of three places: card networks, a stablecoin bank like Augustus, or HSBC's deposit rail ^[13][15][17]. HSBC's version builds on a service already in use. TDS launched in Hong Kong in 2025 as a bank-led blockchain settlement service for corporate clients, according to Crypto Briefing ^[10].

I think the card networks are closer to charging for agent payments, because HSBC's is the only one of the four tests run on a testnet ^[20]. The counter-thesis belongs to Citrini Research. "AI agents move programmatically, 24/7, across applications, and it's only logical that money and financial assets eventually will, too," the firm wrote in an Oct. 8 report ^[18]. TDS already moves corporate funds around the clock ^[9], and Ant supplies the agent layer ^[3]. An agent paying through the live service for a named corporate client, at a disclosed price, would prove the card view wrong.

Whether a bank deposit can carry payments this small depends on what each check costs. If each payment is under $2 ^[4], a million agent purchases settle less than $2 million in value ^[22], and every one of them goes through HSBC's real-time risk check ^[3]. Crypto Briefing said there were no confirmed transaction values beyond the test environment ^[7].
