Fixed Income – Upcoming Market Structure Changes
The purpose of this Service Announcement is to notify customers that there will be changes to the current market structure for Fixed Income securities.
These changes are in relation to London Stock Exchange’s announcement on 9 March 2017 outlining its intention to launch the International Securities Market (ISM), an additional market for the issuance of primary debt targeted at institutional and professional investors. The ISM is an exchange-regulated market, a multilateral trading facility (MTF), which will operate alongside London Stock Exchange plc’s other markets. For additional information please see the dedicated ISM webpage at
The new sectors for Fixed Income securities set out below will be going live in CDS, from Thursday 20 April 2017. We will update the market when these sectors are expected to be available in production in due course. No instruments will be moved to the new sectors in production until this time.
Full details of the new sectors are available in the Millennium Exchange Business Parameters document, which is the 2nd download at the bottom of:
