Hong Kong pushes wholesale CBDC for after-hours derivatives

On Nov. 12, Hong Kong Secretary for Financial Services and the Treasury 许正宇 said the city was pushing to introduce a wholesale central bank digital currency, or wCBDC, “during derivatives trading after the market closes.”

The comment came at the opening of IMC’s new Hong Kong office. That setting matters because it places digital currency inside a specific operating window, rather than an open-ended experiment in digital money.

许正宇 also cited “preparations for T+1 settlement in the stock market.” He pointed to efforts to support a broader range of indexes, index-tracking exchange-traded funds and derivatives.

Together, the comments connect three pieces of market structure: trading hours, the settlement cycle and the money used to settle trades. Each has implications for the others, even though the announcement leaves the implementation details unstated.

What does this change for market operators?

For derivatives participants, the proposal puts a defined trading window at the center of the discussion. A session that continues after the main market closes raises an obvious operational issue: participants need a way to settle trades when the usual trading day has ended.

Hong Kong is considering longer trading hours starting with derivatives. The wCBDC proposal sits within that discussion. Longer hours provide the context, not a separate initiative.

The announcement does not specify a launch date, participating institutions or detailed settlement mechanics. Those points remain open. What traders can assess now is the direction: Hong Kong is considering tokenized money alongside a longer derivatives window and a revised stock settlement cycle.

That distinction separates the proposal from a general call for more digital money. It names the product, the market and the part of the session where the product would be used.

The index and product agenda has its own role in the remarks. 许正宇 cited more indexes, index-tracking exchange-traded funds and derivatives, without naming specific products or schedules.

A broader settlement agenda

许正宇 also referred to settlement using tokenized money and the digital Hong Kong dollar. The remarks do not explain how either would work with longer trading sessions, or how they would fit with T+1 settlement for stocks.

That leaves a practical division between the proposals. T+1 concerns the stock settlement cycle. The wCBDC discussion concerns derivatives activity after the close. The tokenized-money and digital-Hong-Kong-dollar references extend the conversation into settlement design.

For exchanges, market makers and funds, the consequence is operational. Longer sessions change when trading and post-trade support must run. Settlement design would determine what money is available when those trades need to be completed.

These are not interchangeable changes. The remarks place them within one market-hours discussion, but they do not make them a single launch. Any rollout would still need rules covering timing, access and settlement.

The next test

Hong Kong’s longer-hours discussion starts with derivatives, not a wholesale extension across all markets. That keeps the initial focus on a defined segment where extended trading and tokenized settlement can be considered together.

The open question is sequencing. Preparations for T+1 stock settlement, a possible wCBDC window and longer derivatives hours could advance separately. The institutional test is whether the authorities can bring them into one operating timetable.

Without a launch timetable, Hong Kong’s next test is whether the proposals become a coordinated schedule for after-hours wCBDC trading, longer derivatives hours and related settlement arrangements.
