Hong Kong is amending its Stamp Duty Ordinance to allow dual-counter securities traded in yuan to pay stamp duty directly in renminbi. The legislative change removes a structural friction that currently forces offshore RMB-denominated trades into a separate tax process. The immediate consequence is lower operational cost for market makers and institutional investors holding or trading yuan-denominated assets, including the city's growing suite of crypto-linked ETFs.
Stamp Duty Amendment and the Dual-Counter Gap
The amendment is not a standalone tax tweak. It is part of a broader push by Hong Kong authorities to deepen offshore RMB liquidity and position the city as a regional hub for digital asset trading. Since Hong Kong introduced a regulatory framework for virtual asset trading platforms in June 2023, several issuers have launched spot Bitcoin and Ethereum ETFs denominated in both HKD and RMB. The dual-currency structure lets investors choose their settlement currency. The stamp duty treatment has been inconsistent. Under current rules, RMB-denominated trades face a separate stamp duty process that adds settlement lag and cost. Aligning the tax treatment closes that gap.
For crypto ETF market makers, the change reduces the spread between the HKD and RMB counters. That matters because liquidity in the RMB-denominated tranches has been thin relative to the HKD versions. A narrower cost gap should encourage more arbitrage activity between the two counters. Tighter pricing attracts larger institutional flows. The Hong Kong Exchange (HKEX) has been actively promoting the dual-counter model since its launch in June 2023. This stamp duty amendment is the next logical step to make the structure viable at scale.
Affected Assets: Hong Kong's Crypto ETFs
The primary beneficiaries are the issuers and market makers of Hong Kong-listed crypto ETFs. The three largest spot Bitcoin ETFs in Hong Kong – managed by China Asset Management, Harvest Global, and Bosera International – all offer RMB-denominated share classes. The same applies to the Ethereum ETFs launched in April 2024. If the amendment passes, these RMB counters become more cost-competitive. They could draw in mainland Chinese capital that prefers to settle in yuan rather than convert to HKD first.
