Underwriter

In which transactions does an Underwriter operate?

An Underwriter is a bank or financial institution that accepts financial risk as part of a transaction. The role appears primarily in capital markets financing, including:

Debt Capital Markets (DCM)

  • bond issuances;
  • convertible bond issuances.

Equity Capital Markets (ECM)

Structured finance

The term Underwriter is also used in the insurance sector, but in capital markets and banking it refers specifically to the bank that guarantees the success of a financing or issuance.


What is the role of an Underwriter?

The Underwriter’s core responsibility is to “underwrite” or assume a risk on behalf of the issuer.

1. In capital markets transactions (DCM or ECM)

The Underwriter guarantees the completion of the issuance, ensuring the issuer receives the full amount of financing sought.
This may involve:

  • Purchasing the securities (bonds or shares) directly from the issuer or selling shareholder, with the intention to resell them to investors.
  • Providing a firm underwriting commitment, guaranteeing to buy any securities not taken up by the market.
  • Supporting the placement process to ensure broad investor demand.

2. In structured finance

The Underwriter:

  • analyses the credit and transaction risks;
  • commits to providing funding or guaranteeing the financing;
  • supports execution by ensuring liquidity is available.

Large transactions often require several Underwriters, who share the financial risk and coordinate the placement.
