Hong Kong has launched a pilot that puts its wholesale central bank digital currency, e-HKD, directly into the plumbing of its derivatives market. On 18 June 2026, Hong Kong Exchanges and Clearing (HKEX) and the Hong Kong Monetary Authority (HKMA) announced they are testing e-HKD to support advance margin payments during after-hours trading sessions – a move that could fix long-standing funding gaps when traditional banks are closed.
The trial targets a critical operational pain point: under the current system, clearing participants must submit advance margin deposit requests to HKFE Clearing Corporation by 3 p.m. if those funds are to be recognized for the following after-hours session. By using a wholesale CBDC that can operate around the clock, the pilot would let clearing firms transfer margin outside normal banking hours without altering existing workflows.
Real-value testing in a live market environment
HKEX has invited clearing members under HKFE Clearing Corporation to join on a voluntary basis and test e-HKD with actual value under controlled conditions. Any broader rollout, the exchange stressed, will depend on regulatory approvals, market readiness and operational considerations.
“By exploring the use of CBDC, we aim to provide a more flexible and timely payment option outside of regular business hours, and address longstanding operational pain points in the industry,” said Vanessa Lau, Chief Operating Officer at HKEX. “This project reflects the shared commitment of HKEX and the HKMA to embracing innovation, strengthening the resilience of our markets and reinforcing Hong Kong’s position as a leading international financial centre.”
Howard Lee, Deputy Chief Executive of the HKMA, added that the pilot would test a wholesale CBDC application in a live market setting for the first time in Hong Kong.
Wholesale CBDC strategy takes shape
The initiative builds on earlier HKMA work. After completing the second phase of its digital currency pilot program in 2025, the central bank concluded that institutional demand for e-HKD far exceeded retail interest. It subsequently pivoted toward wholesale deployment, exploring programmable payments, tokenized deposits and cost-efficient settlement. That pivot now lands inside the derivatives market, with e-HKD being used to strengthen risk management during extended trading hours when bank rails are unavailable.
The pilot provides one of the most tangible use cases yet for a wholesale CBDC within existing capital market infrastructure. If successful, it could shape how margin funding and settlement are handled not only in Hong Kong but also in other global financial hubs exploring digital central bank money.
