What are the different types of non-interest income and expenses for banks?

Non-interest income for banks includes fees from services like account maintenance, ATM usage, and transaction processing, as well as revenue from investment banking, asset management, and trading activities. Expenses in this category may encompass costs related to service delivery, technology maintenance, and regulatory compliance. Additionally, banks may incur expenses from losses on non-performing loans or penalties. These non-interest components are crucial for diversifying income sources and enhancing overall profitability.
