Hong Kong sells tax certainty, Singapore sells model access: domicile is now an ops decision

Hong Kong lawmakers are still working through legislation that would give tax incentives to fund managers and family offices while leaving proprietary trading companies outside the perimeter ^[5][6]. Singapore's financial institutions are answering with something a tax code cannot supply: access to frontier AI tooling from both the United States and China ^[1][11]. That turns a domicile choice into an operating-capability choice, and the two are not priced the same way.

The framing comes from Kher Sheng Lee, co-head of Asia-Pacific at the Alternative Investment Management Association, who told Cryptopolitan that both offers are versions of the same good. "With tax, you want to know how much you will pay to put your business on a firm footing. For AI, you need to make sure you have access to the latest tools," he said ^[3]. AIMA itself flagged in July that potential tax rollbacks were pushing senior Singapore hedge fund and private equity people toward Hong Kong ^[4]. So the tax pull is real and already moving people.

The constraint on the other side is not policy, it is plumbing. China's Great Firewall shuts out OpenAI and Anthropic, and while Hong Kong sits outside mainland censorship, US technology firms block the territory themselves ^[9]. For a quant shop, that is not a compliance footnote; it is a research input that either arrives or does not. Justin Tan of LEK Consulting says the technology gap is already prompting Hong Kong-based quant funds to weigh moving research and trading operations to Singapore, which he called "a bit of a sweet spot" on technology access ^[10]. Singapore's positioning is that it can draw on both sides, including models from Moonshot and DeepSeek ^[11]. Kerry Goh, chief executive of Kamet Capital, argues that incorporating there reassures global clients their intellectual property stays clear of both Chinese and US restrictions ^[12].

The clearest data point is a firm, not a forecast. Citadel gave its Hong Kong-based quantitative research staff a choice of relocating to Singapore or Miami or leaving, and according to people cited in the report, data security concerns around the staff who hold the firm's core intellectual property drove the decision ^[13]. That is a capability decision taken ahead of, and independent of, whatever Hong Kong's tax bill eventually says.

The tax side is not trivial either. The proposed Hong Kong changes cover the treatment of carried interest and performance fees ^[14], and the report notes that a number of Asian fund managers earned performance bonuses above $1 million last year, with the largest around $50 million or more ^[15] - roughly fifty times the lower figure, which is where a marginal rate change stops being a rounding error ^[17]. Hong Kong's Financial Services and the Treasury Bureau frames the incentives as a way to pull in private credit activity while complementing digital assets and precious metals and commodities trading ^[16]. The same bureau says proprietary trading is excluded because it falls outside the definition of a fund ^[7], although reports suggest Hong Kong is looking for a way to bring firms such as Jane Street inside the regime ^[8].

Watch whether the exclusion for proprietary traders survives drafting, because Jane Street, Citadel Securities and Jump Trading are exactly the firms with the heaviest compute and model dependencies ^[6]. If Hong Kong widens the tax net but cannot fix model access, it will be bidding for entities whose research functions have already left.
