The Financial Conduct Authority has finalised a revised UK short selling regime intended to simplify rules and reduce firms’ reporting burdens while maintaining regulatory oversight. The framework reflects legislative changes under the Government’s repeal and replace programme, under which the FCA will publish aggregated data on the overall size of net short positions in each company rather than identifying individual short sellers. The rules introduce a more workable reporting timetable by giving firms additional time to calculate and submit short position reports. Market maker requirements are also streamlined, with eligible firms moving from multiple exemption notifications to an annual confirmation. The FCA’s powers to intervene in exceptional market conditions, including through emergency measures, remain unchanged.
