Hong Kong regulator unveils stablecoin sandbox
Following December's release of proposed fiat-referenced stablecoin regulations, the Hong Kong Monetary Authority (HKMA) has progressed further with the introduction of a stablecoin sandbox.

Formulating a regulatory regime
The regulatory sandbox, announced through a press release published to the regulator’s website on March 12, encompasses stablecoin currencies beyond the Hong Kong dollar, although the HKMA refrained from specifying particular currencies.
Eddie Yue, CEO of the HKMA, emphasized the sandbox's role as a platform for constructive dialogue between the regulatory authority and the industry. Yue stated:
"The sandbox arrangement serves as an effective channel for the HKMA and the industry to exchange views on the proposed regulatory regime.”
Yue further noted that such engagement is pivotal for formulating regulatory requirements conducive to the sustainable and responsible growth of the stablecoin issuance business. The stablecoin sandbox finds its digital footprint within the International Financial Centre on the HKMA's website. The documentation accompanying the sandbox outlines several key requirements for potential participants.
These include demonstrating genuine interest and a feasible plan for issuing fiat-referenced stablecoins in Hong Kong, as well as a concrete strategy for engagement within the sandbox. Additionally, applicants must exhibit a reasonable prospect of compliance with the proposed regulatory framework.
Minimum capital requirements
One notable regulation proposed stipulates that issuers must be Hong Kong-based entities with a minimum capital requirement of HK$25 million ($3.2 million) or 2% of the stablecoin issuance, whichever is higher. The HKMA remains vigilant regarding public announcements by sandbox participants, ensuring that such declarations do not misconstrue endorsement or accreditation from the regulatory authority.
In late January, reports suggested discussions between Harvest Global Investment, RD Technologies, Venture Smart Financial Holdings and the HKMA regarding their potential entry into the sandbox. Harvest Global Investment, boasting over $200 billion in assets under management, signifies a significant player in this evolving digital assets space.
RD Technologies took to the X social media platform to publicize its approval of the HKMA’s stablecoin sandbox. It also availed of the opportunity to outline that it’s in the process of launching a Hong Kong dollar (HKD)-based stablecoin, which will be known by the short-code HKDR.
Hong Kong-based fintech firm AnchorX also chimed in, stating that the sandbox is “a pivotal step forward for the industry, enabling informed dialogue and collaboration between regulators and fintech innovators.”
Like RD Technologies, AnchorX is also looking to get involved in the stablecoin business, having developed the AxHKD Hong Kong dollar-based stablecoin, which it is currently beta testing, in collaboration with Conflux Network.
Juan Leon, crypto analyst with Bitwise Asset Management, suggested that the move is a great initiative, while calling on the U.S. Federal Reserve Chair Jerome Powell to follow Hong Kong’s example.
On the tokenization front, Hong Kong made headlines in 2023 with the issuance of the world's largest native digital bond — a green bond exceeding $750 million. Late last year, it also proposed regulations relative to tokenization of real-world assets.
Guidance provided to banks on tokenization, coupled with plans for forthcoming legislation, further solidifies Hong Kong's position as a trailblazer in the realm of digital finance.
