China orders trading servers out of exchanges
China’s market watchdog has ordered the removal of co-located trading servers from exchange data centres, a step that strikes at the core of high-frequency trading strategies by stripping away microsecond advantages and reshaping how orders reach the market. The directive, conveyed to brokerages and proprietary trading firms over the past week, requires firms to relocate servers that sit inside or adjacent to exchange facilities, a practice that has allowed algorithmic traders to exploit ultra-low latency connections. By mandating physical separation, regulators aim to level access speeds across participants and curb behaviour blamed for sharp intraday swings. Officials at the China Securities Regulatory Commission have framed the move as part of a broader effort to restore fairness and stability at a time when volatility has tested investor confidence. Exchanges have begun coordinating timelines with members, while technology vendors assess the operational impact of migrating equipment and reconfiguring networks. At the heart of the change is co-location, a service long offered by major venues such as the Shanghai Stock Exchange and the Shenzhen Stock Exchange. By placing servers in the same buildings as matching engines, firms could shave milliseconds off order transmission, a decisive edge for strategies that depend on speed. The new rule eliminates that edge by forcing all traders to connect from outside facilities, effectively compressing the speed differential. Market participants say the immediate effect will be uneven. Firms that rely heavily on latency-sensitive strategies face higher costs and potential revenue declines, while asset managers and retail-focused brokers expect fewer instances of sudden price dislocations triggered by rapid-fire trades. Some proprietary desks have already paused certain algorithms as engineers test alternative connectivity routes. Regulators’ concerns extend beyond fairness. Officials have grown wary of feedback loops in which automated strategies amplify short-term moves, especially during thin liquidity. Episodes of abrupt swings in small- and mid-cap shares have sharpened scrutiny of trading practices that can overwhelm order books in fractions of a second. By slowing the fastest participants, authorities believe markets will better reflect underlying supply and demand. The measure also aligns with a wider tightening of oversight on quantitative trading. Over the past year, exchanges have refined monitoring of order-to-trade ratios, imposed stricter reporting on algorithmic strategies, and increased penalties for disruptive behaviour. Server removal adds a structural constraint that complements those rules, shifting the emphasis from after-the-fact enforcement to preventative design. Technology providers are bracing for a wave of changes. Data centre operators linked to exchanges will see reduced demand for premium co-location services, while telecom firms may benefit as traders invest in faster external links to mitigate latency losses. Network optimisation, time-synchronisation tools and smarter order-routing software are expected to attract investment as firms adapt. There are risks of short-term disruption. Moving servers involves downtime, testing and regulatory approvals, raising the possibility of temporary liquidity dips in certain instruments. Exchanges have signalled flexibility on implementation schedules to avoid disorderly conditions, though the direction of policy is clear. Compliance teams are urging firms to prioritise stability over speed during the transition. Internationally, the decision is being watched closely. Other jurisdictions have grappled with the balance between innovation and fairness, with mixed approaches ranging from speed bumps to transaction taxes. China’s choice to remove co-location altogether is among the most decisive interventions to date and could influence debates elsewhere, particularly in markets where retail participation is high.
