A more thorough explanation:

Definition: The institutional market refers to the demand for short-term funds and commercial paper among large investors and corporations.

Example: A large investment bank may need to borrow funds for a short period of time to finance its operations. It can do so by issuing commercial paper, which is a type of short-term debt instrument. The buyers of this commercial paper are typically institutional investors such as pension funds, insurance companies, and mutual funds.

This example illustrates how the institutional market is a segment of the overall market where large investors and corporations participate in buying and selling financial instruments such as commercial paper, treasury bills, and other short-term debt securities. These investors have significant financial resources and are able to invest in large amounts, which makes them an important part of the financial system.
