The net interest margin is a key indicator of bank profitability. It represents the difference between the interest income generated from loans and the interest paid out on deposits, relative to the total amount of interest-earning assets. By calculating the net interest margin, banks can assess how effectively they are managing their interest income compared to their interest expense, which is crucial for determining overall financial performance.

A higher net interest margin indicates that a bank is able to earn more from its lending activities than it spends on interest to attract deposits, thus signaling strong profitability. This metric provides insights into the bank's ability to generate profit from its core operations of lending and managing deposits.

While loans issued to customers and deposits collected are important factors for a bank's operations, they do not directly measure profitability. Similarly, operational efficiency is more related to the management of resources and processes within the bank rather than the specific profitability aspect that net interest margin encapsulates. Therefore, focusing on net interest margin primarily highlights the bank's profitability.
