Hook
Over the past week, a quiet but significant policy shift has rippled through Hong Kong's financial corridors: the city has excluded proprietary trading firms from its carried interest tax concession. For those of us who have spent years navigating the intersection of blockchain and regulation, this is not a mere footnote. It is a calibrated signal. The carried interest regime, introduced in 2021 with a 0% tax rate, was Hong Kong's crown jewel for attracting hedge funds and private equity. Now, by carving out prop trading firms, the government is drawing a line in the sand. And if you are a crypto market maker or a quant fund operating out of the Lion Rock, your next move just became a lot more complicated.
Context
To understand why this matters, we need to revisit the original intent. Hong Kong's carried interest tax concession was designed to supercharge the city's asset management ecosystem. It targeted fund managers who generate returns for external investors, not firms that trade their own capital. Proprietary trading houses—including many crypto market makers like Wintermute, Jump Crypto, and Amber Group—operate on a different model. They use their own balance sheets to provide liquidity, capture arbitrage, and execute high-frequency strategies. By excluding them, Hong Kong is effectively saying: "We want value creation for clients, not speculative self-dealing."
This is a shift from the broad embrace of Web3 that many expected after the city launched its VASP licensing regime in 2023. The narrative of Hong Kong as a crypto hub has been running hot, driven by retail-friendly policies, stablecoin legislation progress, and the proximity to mainland China's capital. But this tax move reveals a more nuanced reality: selective openness. The government is not anti-crypto; it is anti-blanket subsidy. It wants to attract businesses that align with its long-term financial stability goals, not those that simply optimize for tax arbitrage.
Core: Tech and Values Analysis
From a technical-research perspective, this policy change is not about blockchain consensus mechanisms or smart contract vulnerabilities. It is about the infrastructure layer of financial regulation—the taxes and entity structures that determine where capital flows. During my years building ChainBridge, I saw how tax policy directly shapes developer and capital allocation decisions. A 0% carried interest rate can make the difference between a fund setting up in Hong Kong versus Singapore or Dubai. Now, that advantage is partially revoked for a specific class of firms.
The core insight lies in the granularity of the exclusion. Hong Kong's tax authorities are not just randomly picking on prop trading. They are implicitly distinguishing between two functions: asset management (managing external funds) and proprietary trading (trading own capital). In traditional finance, this distinction is clear. But in crypto, many firms blend both roles. A market maker like Wintermute might trade its own capital but also provide liquidity services that benefit the entire ecosystem. The exclusion creates a classification headache. Is a crypto quant fund that earns performance fees from external LPs a "proprietary trading firm"? If it uses its own capital for part of the strategy, where is the line drawn?
This ambiguity is the real risk. Based on my audit experience with DeFi protocols, I have seen how regulatory uncertainty cascades. When a jurisdiction's tax rules are unclear, firms either delay decisions or over-comply. Both outcomes are costly. For Hong Kong, the immediate effect will be a cooling of enthusiasm among crypto-native firms that were considering relocation. The city's VASP licensing is expensive and time-consuming; adding tax uncertainty on top could tip the balance toward Singapore, which offers clearer tax incentives for family offices and funds through its 13O/13U schemes.
But there is a deeper structural story. The exclusion is likely driven by international pressure, particularly from the OECD's Pillar Two global minimum tax rules. Hong Kong has committed to implementing a local minimum top-up tax by 2025. By narrowing the carried interest concession, the city is preemptively avoiding a conflict with international standards. It is sacrificing short-term tax attractiveness for long-term compliance and reputation. This is a strategic trade-off: lose some prop trading firms but gain credibility as a responsible financial center. Code is law, but humans are the protocol. The decision reflects human judgment about what kind of financial hub Hong Kong wants to be.
Contrarian: The Pragmatism Test
The counter-intuitive angle is that this exclusion might actually benefit Hong Kong's Web3 ecosystem in the long run. Think about it: prop trading firms are often the most volatile participants. They chase tax breaks, leave when they expire, and contribute little to the local talent pool or innovation. In contrast, asset managers who handle external capital are more likely to build long-term relationships, hire local analysts, and invest in infrastructure. By excluding prop trading, Hong Kong is signaling that it wants sticky, value-add businesses, not footloose arbitrageurs.
Moreover, the narrative that this is a death blow to Hong Kong's crypto ambitions is overblown. The city's core advantages remain: common law system, deep capital markets, gateway to mainland China. Even if a few market makers relocate to Dubai or Singapore, the bulk of asset management—and the fee income it generates—will likely stay. The crypto market is not a zero-sum game for physical offices. Many firms maintain multiple entities across jurisdictions. The lost prop trading tax revenue is a small price to pay for a cleaner tax regime that attracts institutional investors who care about compliance.
Another blind spot: this policy could accelerate the shift toward decentralized organizational structures. If corporate tax advantages erode, more funds might consider DAO structures that operate without a single jurisdiction. That would be a net positive for the ethos of decentralization. Trust is earned in drops, lost in buckets. Hong Kong is betting that dropping a few prop trading firms will not cost it the bucket of trust it has built with institutional asset managers.
Takeaway
Hong Kong's exclusion of proprietary trading firms from carried interest tax concessions is not a retreat from Web3—it is a pivot. The city is choosing to be a serious financial hub for managed assets rather than a free-for-all tax haven for speculative traders. For the crypto industry, this is a wake-up call: regulatory advantages are not permanent. The future belongs to those who build resilient, multi-jurisdictional strategies that can absorb policy shifts without panic. Hold through the noise, build through the silence. The real test will be whether Hong Kong's other levers—stablecoin legislation, VASP licensing, and connectivity to mainland China—can compensate for this tax narrowing. If they can, the city will emerge stronger. If not, we will see capital migrate to where the incentives align. Either way, the market will teach us the next lesson. The question is: are we ready to learn?
