Secondary Market:
Bangladesh Bank initiated to automate the process of trading and settlement of Government securities transactions in October 2011. The secondary G-Sec market in Bangladesh is comprised of trading in BB’s own electronic system and trading through Dhaka Stock Exchange (DSE) and Chattogram Stock Exchange (CSE) platform.

1. Secondary trading through BB’s Electronic System:
   Bangladesh Bank has a separate electronic system for secondary trading which is called Market Infrastructure Module(MI Module). In this system secondary trading takes place in two ways:
   • (A) Over-the-Counter (OTC): Trades are made through the OTC process, which involves members negotiating outside the trading site (e.g., over the telephone). If a bargain is reached through negotiation, it must be reported to the system for settlement subsequently. When involving parties complete the trading procedure, and the system accepts the transaction, the data is automatically sent to BB's Core Banking System (CBS) for real-time clearing and settlement of funds. Following that, the traded securities would be sent automatically to the buyer's securities account in the MI module.
   • (B) Government Securities Order-Matching Trading Platform (GSOM): GSOM is an anonymous order-matching trading system of G-Sec that is electronic, screen-based, and order-driven. It gives member dealers the ability to trade on the secondary market in real-time. The trading solution's primary components are order processing and matching. The trading solution's matching engine delivers algorithms that allow members to trade instantly. GSOM has improved the transparency of G-Sec's secondary market transactions. Bids (purchase orders) and offers (sell orders) can be placed immediately on the trader work station screen by Member Dealers (banks and FIs). Other investors, such as individuals and institutions, insurance companies, corporations, provident funds, pension funds etc. are eligible to trade G-Sec through member dealers working in Bangladesh.
2. Secondary trading through Stock Exchange:
   Trading of Bangladesh Government Treasury Bonds(BGTB) has been started in Stock Exchange (DSE & CSE) since 10 October 2022. Any investor having a Beneficial Owner Identification Number (BOID) can purchase BGTB from Stock Exchange (DSE & CSE) platform. After the purchase a BPID will be opened (if not available beforehand) against the investor in order to settle the securities in BB’s electronic system.

On the other hand, an investor (existing holder of BPID) can transfer his bond portfolio from BB’s electronic system to Stock Exchange for trading there. For this purpose, the investor requires to fill in the relevant transfer forms and submit it to the corresponding bank to transfer partial or entire portion of their holding of BGTB from BB’s Electronic System. After taking necessary initiatives the bank sends the relevant transfer information to Stock Exchange.
