Final answer:
A banker using client information from a loan application to sell other products engages in cross-selling, using the detailed financial information collected to tailor additional financial services.
Step-by-step explanation:
When a banker uses the information a client enters in a loan application to sell other financial products to this client, this action is often referred to as cross-selling. In the financial capital market, banks and other institutions gather detailed personal and financial information from prospective borrowers to assess their creditworthiness and to make informed lending decisions. This information can include income sources, credit checks, requirements for cosigners, and collateral. Banks, as intermediaries, may utilize this information to tailor additional products and services that could benefit the client, based on their financial profile and needs.
