HKMA, HKEX Test e-HKD for After-Hours Derivatives Trading

Hong Kong Exchanges and Clearing Limited (HKEX) and the Hong Kong Monetary Authority (HKMA) have announced a pilot project to test the use of e-HKD, a wholesale central bank digital currency (CBDC), for margin payments during the after-hours trading (AHT) session in the derivatives market. The initiative, unveiled on June 18, 2026, aims to enhance efficiency and flexibility in a market that has seen consistent growth, with average daily volumes exceeding 1.78 million contracts in the first five months of the year.

Currently, Clearing Participants (CPs) are required to submit advance margin deposit requests by 3:00 p.m. for funds to be credited for AHT. Under the pilot, e-HKD will facilitate real-time margin payments on a 24/7 basis, reducing operational bottlenecks. HKEX has invited CPs to participate in Real-Value Trial Transactions on an optional basis, though broader adoption will depend on regulatory approvals and market readiness.

This move reflects Hong Kong's broader strategy to position itself as a global hub for digital money and tokenised assets. The e-HKD initiative began in May 2023 as part of HKMA’s ‘three-rail’ strategy for CBDC development, which spans retail, wholesale, and cross-border applications. Since then, the project has evolved, with Phase 2—renamed "Project e-HKD+"—focusing on interoperability between public and private digital currencies along with advanced use cases like atomic settlement and programmability.

HKEX Chief Operating Officer Vanessa Lau described the pilot as an opportunity to "address longstanding operational pain points" in after-hours trading, while HKMA Deputy Chief Executive Howard Lee highlighted the project as a "live market demonstration" of wholesale CBDC applications. The collaboration underscores Hong Kong's commitment to financial innovation and infrastructure resilience.

This pilot also aligns with other HKMA efforts, such as Project Ensemble, which explores real-value transactions using tokenised deposits and digital assets. Launched in late 2025, the initiative includes participation from seven commercial banks and focuses on tokenised money-market funds and real-time liquidity management within a sandbox environment. Together, these projects highlight Hong Kong’s focus on building a comprehensive digital payment ecosystem.

For traders, the ability to make margin payments outside regular banking hours could streamline risk management and reduce settlement delays. If successful, the pilot could pave the way for wider adoption of digital currencies in real-world financial markets, solidifying Hong Kong's leadership in CBDC innovation.

The outcomes of the e-HKD trial, along with other HKMA-led initiatives, will likely influence future regulations and adoption timelines. Market participants should monitor updates closely, as broader implementation could reshape trading operations and risk management strategies in Hong Kong’s derivatives market.
