Spain, with an outstanding government debt of more than 300 billion Euros, is one of the most important debt issuers in Europe. Although the Spanish Benchmark securities have been and are successfully traded on EuroMTS since October 1999, the market participants together with MTS decided to create a domestic market on its own, to respond to the need of trading the whole yield curve in a more efficient and Pan-European manner.

MTS Spain was successfully launched with full support of its participants on May 27th 2002, after the Cabinet of Ministers gave green light to MTS Spain's application to obtain the license of Sistema Organizado de Negociacion (SON). Thanks to this license MTS Spain has attained the status of Secondary Supervised Spanish Market for the trading of the Spanish Public Debt.
