HKEX Tightens Order Price Limit to Five Times from Nine Times

This is a structural market-plumbing change rather than a headline event: narrowing the order input band from nine times to five times the last close constrains how far from the reference price orders can be entered, which matters most for thin or volatile names where wide limit orders are used defensively. The exemption for structured products signals the rule targets cash-equity order behavior, not issuer hedging flows. Whether the tighter band changes liquidity provision or order placement habits once live is the open question, and the long lead time to implementation gives participants room to adjust.
