MEXICO CITY, Nov 15 (Reuters) - Mexico's lower house on Wednesday passed a bill aimed at revamping national stock exchanges, a long-awaited move meant to boost trading following a spate of delistings from the main market in recent years. The bill loosens regulations for companies to go public, speeding up the process and reducing the costs involved, said Mexico's largest market operator, the Bolsa Mexicana de Valores, in a statement. The bill had previously passed in the Senate, and will now be sent to President Andres Manuel Lopez Obrador's desk to be signed into law. Just 138 companies are listed on the Bolsa Mexicana de Valores, which has gone six years without a new listing, barring spin-offs.
