European Securities and Markets Authority Publishes Final Guidelines on Circuit Breakers Under MiFID II
04/06/2017
The European Securities and Markets Authority has published Guidelines on the calibration of circuit breakers and the publication of trading halts under the revised Markets in Financial Instruments Directive. MiFID II requires regulated markets temporarily to halt or constrain trading if there is a significant price movement in a financial instrument (equity, equity-like and debt instruments) on that market or a related market in a short period. Regulated markets must also, in exceptional cases, cancel, vary or correct any transaction. ESMA is required to develop guidelines on the calibration of those trading halts, taking into account the liquidity of the different asset classes and sub-classes, the nature of the market model and types of users. The Final Guidelines outline further details on the parameters that trading venues should consider when calibrating their circuit breakers. ESMA emphasizes that consideration should be given not only to trading halts, but also order price collars. Trading venues should also immediately make public details of the activation of a trading halt, the type of trading halt, the trading phase in which it was triggered, the eventual extension and the end of the halt. National regulators have until two months from date of publication in all EU official languages to advise ESMA of whether or not they intend to comply with the final Guidelines.
