NEW YORK, LONDON and STAMFORD, Connecticut, May 25, 2011 -

MarketAxess Holdings Inc. (Nasdaq: MKTX), the operator of a leading
electronic trading platform for U.S. and European high-grade corporate bonds,
emerging markets bonds and other fixed income securities today announced that
RBS is the first dealer to provide streaming, executable markets to

high yield indices (CDX), as well as European indices (iTraxx). Using the
MarketAxess 'streaming markets' protocol, investors are able to initiate

and single names, in all major markets. MarketAxess will provide a broad
suite of straight-through-processing (STP) functionality for CDS trades
taking place on the platform, including connectivity to the available central
clearing counterparties for CDS.

Kelley Millet, President of MarketAxess, said: "We are working with our
dealer and investor clients to support their electronic CDS trading
requirements on a global basis. As the first firm to provide streaming,
executable quotes on the MarketAxess platform RBS is helping to promote the
implementation of electronic CDS trading today, and we expect to add further
dealers to the streaming markets platform for CDS indices in the near future.
MarketAxess expects to qualify as a swap execution facility (SEF) and as such
we are offering a full suite of trading protocols and post-trade connectivity
to support and accelerate electronic trading in the CDS market."

"We are excited to be involved in the launch of CDS trading on
MarketAxess and to be on the forefront of technological innovation in the
marketplace," said Sean Murdock, Managing Director and Head of US Credit
Trading at RBS. "These efforts reinforce our commitment to providing our
