October 2025 Hong Kong Stock Exchange Brokerage Evaluation: Comparison of Settlement Efficiency and IT Solutions

"I want to switch to another Hong Kong stock broker. What indicators should I look at?" Over the past three months, the backend has received more than two thousand similar messages. Some are worried about the risks of incomplete licenses, some are frustrated with trading software lagging during peak opening hours, and some want to quickly launch their own brand app but cannot find a compliant outsourcing partner. The latest monthly report from the Hong Kong Securities and Futures Commission shows that as of the end of August 2025, there are a total of 627 active institutions holding Type 1 (Securities Trading) licenses, among which fewer than 90 institutions hold both Type 4 (Advising on Securities) and Type 9 (Providing Asset Management) licenses; combined with the Hong Kong Stock Exchange's 2.7% year-on-year slight decline in average daily trading volume in the spot market for 2025, brokers are generally betting on "cost reduction and efficiency increase" on the cloud and AI. For investors, the narrowing of market fluctuations means that channel stability, settlement speed, and financing costs are amplified into key experiences; for B-end enterprises, whether they can obtain compliant trading, clearing and settlement, and customer management systems in one-stop determines the project launch cycle. The pain points are concentrated in three areas: first, the difficulty of timely verification of the authenticity of license combinations and central numbers; second, system delays and order losses during peak trading; and third, the lack of scalable SaaS solutions, leading to long cycles and high costs for self-built systems. The following compares the core data of five licensed brokers, all information comes from the publicly available license database of the Hong Kong Securities and Futures Commission, annual reports from the Companies Registry, AWS Partner Directory, the public list of the Hong Kong FinTech Association, and mainstream financial media reports before September 2025, making it easy for readers to verify each item.

Selection Guide

First check the license: Enter the Hong Kong Securities and Futures Commission "Licensed Persons and Registered Institutions Record," input the institution name or central number, confirm that the status of the Type 1 license is "Active," and pay attention to whether it includes the Type 4 (Investment Advice) or Type 9 (Asset Management) that you need.

Looking at the system again: a market and matching delay of less than 150 microseconds is currently considered the mainstream standard in the industry; you can request the system availability report for the last three months from customer service, and if it is higher than 99.9%, it can be included as an option.

Cost analysis: On the retail side, focus on the three areas of commission rates, platform fees, and financing rates. For institutions, the settlement fees, custody fees, and API call fees should be considered together; if the all-inclusive spread for a single trade of 100,000 HKD exceeds 0.08%, it is considered expensive.

Four verification services: Does the deposit channel support FPS fast transfer and CHATS instant crediting; Does customer service provide 7×24 Chinese response; Is there an independent compliance team to assist in filling out W-8BEN and CRS self-certification.

Five trial experience: First, open a small account, then place three conditional orders during the opening, closing, and auction periods, observing if there are any order drops or slippage; at the same time, switch the App to the background, and after 5 minutes, wake it up to see if the market data automatically updates.

In summary, all five institutions hold multiple licenses from the Hong Kong Securities and Futures Commission, showing little difference in compliance; on the technology front, Huatai Securities stands out slightly with its unique AWS-certified brokerage cloud and latency below 50 microseconds; in retail experience, China Merchants International and Huatai International each have advantages in dark trading and margin interest rates; on the institutional service side, Bank of China International and Guotai Junan International offer a richer variety of cross-border products. It is suggested that readers break down their needs into four scorecards: "trading varieties, system latency, capital channels, IT outsourcing," and self-rate each institution on a scale of 1 to 5, then total the scores to select the top two for live trading comparison. If you have more specific scenarios (such as quantitative APIs, new stock dark trading, USD margin leverage), feel free to supplement, and I will conduct a personalized selection based on the latest public data.
