Key Actors in the Modern Banking System

In an economic model with two individuals, one with an initial endowment of a good (grain) and one with none, what is the primary structural change in their financial relationship when a bank is introduced as an intermediary?

The Role of a Financial Intermediary

In a simple economic model, an individual with an initial endowment of a good can lend directly to an individual with no endowment. If a bank is introduced to act as an intermediary, where the first individual deposits the good and the bank then lends it to the second individual, how does the nature of the financial claim held by the original lender change?
