What is Bond Market Association?

Legal Definition
The Bond Market Association (TBMA, previously Public Securities Association or PSA until 1997) was the international trade association for the bond market industry. It had headquarters in New York City and offices in London and Washington, D.C. Twenty per cent of the membership was located outside the United States, while 70 per cent was located outside New York City. TBMA acted as a global voice for bond issuers and traders, and co-ordinated with governments, corporations, and investors. It also had a code of ethics, which required members to behave in a fashion of fairness. On November 1, 2006, The Bond Market Association merged with the Securities Industry Association to form the Securities Industry and Financial Markets Association.
