Primary vs Secondary Market
The primary market where bonds are first issued, and the secondary market where they trade afterward among investors. This distinction is the foundation of the entire DCM ecosystem.
Primary Market — Where Bonds Are Born
The primary market is where issuers first create bonds. Everything here — a corporation issuing bonds to build a factory, a government to fund a budget deficit, a bank to raise capital — begins in this market.
DCM bankers work for this market. Deal structure design (maturity, coupon, currency), investor demand discovery (roadshows, IOIs), pricing, and actual fund receipt all happen in the primary market. When issuance completes, the issuer receives proceeds and investors hold new bonds.
By definition, all primary market transactions are direct between issuer and investor. Already-issued bonds do not trade here.
Secondary Market — Where Bonds Come Alive
The secondary market is where already-issued bonds trade among investors. Unlike equity exchanges, most bond secondary markets operate OTC (Over-the-Counter): dealers (primarily IB S&T desks) quote bid/ask prices and trade directly with investors.
Secondary market liquidity directly affects primary market demand. Active secondary trading of an issuer's bonds signals that investors can sell when needed, which translates into lower interest rates (advantageous for the issuer) at primary issuance.
Bond prices form in real time in the secondary market. These prices become the reference point for primary issuance — expressions like "T+5bps over existing bonds" show this connection.
Key Terms
Trading directly between dealer and investor without a formal exchange. The dominant form of bond secondary market trading.
Existing bonds used as reference points for pricing new issuances. U.S. Treasuries (UST) and German Bunds are key examples.
