Overview

Jamaica Money Market Brokers (JMMB) is a Jamaica-based investment firm with regional operations in the Caribbean. The organization was founded in November 1992 by Joan Duncan and is headquartered in Kingston, Jamaica. Its business developed around money-market and capital-market activity, with the firm becoming associated with the growth of Jamaica's secondary market for debt instruments. This market function helped support trading and liquidity in government and other debt securities after their initial issuance. JMMB expanded beyond Jamaica into other Caribbean markets. The reference material identifies operations in Trinidad and Tobago, the Dominican Republic, and Barbados, giving the organization a regional rather than solely domestic footprint. Its network includes offices in Jamaica and regional locations in those three markets. The cross-border structure reflects the firm's focus on investment and financial-market services within Caribbean economies. The available reference material provides limited detail about the firm's specific product architecture, leadership after its founding, ownership, legal structure, financial performance, or current corporate organization. Accordingly, this dossier does not assign unverified product names, executives, listing information, financial figures, or an official website. What is established is the company's Jamaican origin, its 1992 founding, its association with Joan Duncan, its Kingston headquarters, and its regional presence. JMMB's historical significance lies particularly in its role in helping develop Jamaica's secondary debt market and in extending a Jamaican investment-business model into neighboring Caribbean jurisdictions.

History

Jamaica Money Market Brokers was established in November 1992 by Joan Duncan in Jamaica. The firm's creation occurred in the context of an emerging need for more developed financial-market intermediation and trading infrastructure. It became associated with the development of Jamaica's secondary money market for debt, a segment that enables investors to trade debt securities after their original issuance and can improve liquidity and price discovery. From its Kingston base, JMMB developed a Caribbean regional presence. The documented markets include Jamaica, Trinidad and Tobago, the Dominican Republic, and Barbados. The expansion gave the organization a broader operating geography across English-speaking and Spanish-speaking Caribbean markets. Regional offices in Trinidad, the Dominican Republic, and Barbados complemented the headquarters in Jamaica. The available source material does not document the firm's later corporate milestones in sufficient detail to establish a complete chronology of acquisitions, product launches, leadership changes, ownership transitions, financial results, or regulatory events. It also does not provide enough information to identify a definitive current executive roster or a complete catalogue of investment products. The verifiable historical account therefore centers on the firm's founding, its Kingston headquarters, its role in Jamaica's secondary debt market, and its subsequent regional Caribbean presence.
