The Order Book for Fixed Income Securities (OFIS) is an electronic trading service for order book trading of corporate bonds and other debt securities. The different segments and sectors can accommodate retail- or wholesale-denominated securities, with trading available in GBP, USD, EUR and other currencies. OFIS also includes multilateral trading facility (MTF) segments, allowing member firms to trade non-London-listed securities on an MTF managed and supervised by London Stock Exchange. The preferred settlement system is CREST; however, settlement through Euroclear Bank and Clearstream is also available.
OFIS offers trading for London-listed debt instruments admitted to the regulated market, with separate sectors for retail and wholesale denominations. OFIS also offers an exchange-regulated segment for international debt (MTF), which allows trading of debt listed on other EEA exchanges. This segment also offers two separate sectors for retail and wholesale denominations. Lastly, professional debt listed on the Professional Securities Market (PSM) can also be traded on OFIS on an exchange-regulated segment.
