How Market Makers Affect Stock Liquidity and Risk in China’s STAR Market
Summary
This Chinese-language article discusses the proposed introduction of market making on China’s STAR Market. It explains that market makers continuously quote prices, sell inventory to buyers, and use their own capital to buy from sellers. They bear price risk and seek to earn the bid–ask spread. The article distinguishes systems with one market maker per security from competitive systems with multiple market makers, and notes that major overseas exchanges combine market making with order-driven trading in hybrid structures.
The article presents market making as a potential source of improved stock liquidity, while describing a countervailing risk: research from overseas markets has found that spreads can widen when market makers incur losses. Reduced capital can weaken their capacity and willingness to provide liquidity, particularly if they cannot raise funds quickly. The discussion also raises governance questions when an underwriter and market maker are the same securities firm, including how to control exposure and whether market making could affect underwriting incentives. It summarizes concerns and prior findings but supplies no detailed study design or quantitative evidence in the available text.
