International Organization of Securities Commissions (IOSCO)
IOSCO was created in 1983 when 11 securities regulatory agencies from North and South America, already organized since 1974 as the inter-American regional association, formed a truly international cooperative body. IOSCO has some 180 members from around the world who regulate more than 90% of the world's securities markets.
IOSCO promotes cooperation, mutual assistance, information sharing and the development of standards to improve the regulation of securities markets internationally. IOSCO is a key international standard setting body. As an associate member of IOSCO, the BCSC participates in the Presidents’ Committee meetings at the IOSCO annual conference.
IOSCO has a General Secretariat headquartered in Madrid, Spain. Full meetings are held annually while IOSCO committees meet throughout the year.
IOSCO multilateral MOU
In 2002, IOSCO approved a Multilateral Memorandum of Understanding concerning Consultation, Cooperation and the Exchange of Information (IOSCO MOU) and encouraged all of its members to become signatories. The BCSC has signed the IOSCO MOU 
. The IOSCO MOU co-exists with bi-lateral memoranda of understanding that signatories have signed with other securities regulators.
