Detailed Explanation
Net Interest Margin, or NIM, is a commonly used measure of how effectively a bank earns net interest income from its earning assets. In simplified terms, it relates interest earned minus interest paid to the bank's average earning assets.
NIM is influenced by loan and investment yields, deposit and borrowing costs, the mix of assets and liabilities, competition, interest-rate conditions and other balance-sheet factors.
A higher NIM can support profitability, but it should not be interpreted in isolation. Different types of banks can operate with different business models, customer segments and risk profiles.
