Settlement of trades in the ‘wholesale’ international markets operated by the Exchange, such as the International Order Book, are settled by member firms in the home depository of the security in question (either DTCC or Euroclear Bank).
A member firm may act as, or use the services of, a settlement agent to settle on-Exchange business. Alternately, a member firm may use the services of a model B firm and a list of all accredited model B providers can be found here.
A firm admitted to membership of the London Stock Exchange may request the enforced purchase of securities on behalf of another Exchange member in order to facilitate the settlement of a transaction executed on Exchange. For more information on the buying-in process, please click here.
