What Is Loan-to-Deposit Ratio?

The loan-to-deposit ratio (LTD) compares the total value of a bank's loans to the total value of its deposits. A ratio of 80% means the bank has lent out $0.80 of every dollar deposited. This metric provides insight into both a bank's lending aggressiveness and its liquidity position.

An LTD ratio between 60% and 80% is generally considered healthy — the bank is actively lending (generating interest income) while retaining enough deposits in liquid form to meet normal withdrawal demands. A ratio above 90% may indicate the bank is stretching its deposit base thin, leaving less cushion for unexpected withdrawals. Extremely high ratios (above 100%) mean the bank is funding some loans with non-deposit sources like borrowings from the Federal Home Loan Bank system or other wholesale funding, which can be more expensive and less stable.

Conversely, a very low LTD ratio (below 50%) might indicate the bank is not effectively deploying its deposits, which could pressure profitability. During periods of economic uncertainty, many banks let their LTD ratios decline naturally as they tighten lending standards and deposit inflows exceed loan demand.

For depositors, the LTD ratio provides context for understanding bank liquidity. A bank with a high LTD ratio and low liquidity ratio on BankHealthData warrants extra attention — it may have limited ability to meet large withdrawal demands. However, LTD alone is not a safety red flag; many well-run banks operate successfully with ratios above 85%. The key is whether the bank has other sources of liquidity (such as unencumbered securities or borrowing capacity) to supplement its deposit base during stress periods.
