Financial Intermediation in the Modified Marco-Julia Model

Banks' Guarantee of Repayment and Liquidity for Deposits

In a simplified economy where grain is the only good and medium of exchange, one individual has a surplus of 100 units of grain and wishes to save it for a future period. Another individual has a productive opportunity but currently has no grain and needs to borrow. A bank is established as the sole financial intermediary. Given its fundamental purpose in this economy, what pair of actions will the bank undertake?

In a simplified economic model where grain is the only medium of exchange, there are three actors: an individual with a surplus of grain, an individual with no grain but a productive opportunity, and a bank. Match each actor to their primary financial role within this system.
