London Stock Exchange updates AIM trading rules to extend hours
AIM trading hours extended

The London Stock Exchange is changing trading arrangements for AIM as part of a broader push to improve transparency and market efficiency. The revised trading hours take effect next month, while the exchange is also adding support resources and gathering feedback from market participants.

Highlights

  • London Stock Exchange will implement updated AIM trading regulations with extended hours and liquidity-focused changes effective next month.
  • Additional support measures will be offered to brokers and investors to ease the transition to AIM's revised trading timetable.
  • The exchange is actively collecting market participant feedback to further refine AIM's trading environment and potentially evolve the framework.

AIM trading framework changes from next month

As reported by London Stock Exchange, the updated trading regulations include new trading hours for AIM and are intended to support a broader range of investors. The exchange says the revised framework is designed to improve overall market liquidity as participants prepare for the changes to take effect next month.

Market participants have already been notified of the adjustment, and the exchange is positioning the move as part of its ongoing work to make trading more transparent and efficient. The announcement indicates that further guidance will be made available to help traders adapt to the revised setup.

Support measures and market impact

Alongside the rule change, the exchange says it will provide additional resources for traders as they transition to the new hours. That support could help reduce operational friction for brokers and investors using AIM while the market adjusts to the revised timetable.

The exchange is also collecting feedback from market participants to refine the trading environment further. That consultation suggests the framework may continue to evolve as the London market operator assesses how the changes affect liquidity and access across the UK growth market.

In our earlier coverage of the Bank of England’s assessment of the UK economy after the energy price shock, we noted officials’ view that the impact has been less severe than initially expected, supported by fiscal policy and central bank measures. The same update also flagged persistent risks from inflation and market volatility, underscoring the need for continued monitoring and adaptive policy to protect financial stability.
