As smaller banks rely more for their income on loans than larger banks, they have shorter liabilities structure , hence they need to manage credit risk more aggressively.

This statement seems to be more of a fact or an assertion rather than a question. However, I can break it down for you to understand better:

1. "Smaller banks rely more for their income on loans than larger banks": This means that smaller banks depend more on the interest they earn from loans for their income compared to larger banks. Larger banks have more diverse sources of income, such as investments, fees, and services.

2. "They have shorter liabilities structure": This means that smaller banks typically have their liabilities due sooner than larger banks. This could be due to a variety of reasons, such as the types of deposits they accept or the terms of their borrowings.

3. "Hence they need to manage credit risk more aggressively": Credit risk is the risk that a borrower will not repay a loan. Because smaller banks rely more on loan income and have shorter-term liabilities, they need to be more careful about who they lend to. They need to ensure that their borrowers are likely to repay their loans on time. This is what is meant by managing credit risk aggressively. They may use stricter lending criteria, charge higher interest rates to riskier borrowers, or use other strategies to manage this risk.
