A negative gap occurs in the banking sector when a bank’s interest-sensitive liabilities exceed its interest-sensitive assets. This can lead to potential financial imbalances, particularly affected by changes in interest rates.
Interest-Sensitive Assets and Liabilities
- Interest-Sensitive Assets: These are bank assets such as loans and investments that change in value with interest rate fluctuations.
- Interest-Sensitive Liabilities: These are bank liabilities like savings accounts, certificates of deposit, and borrowings that are affected by changes in interest rates.
Mechanics of a Negative Gap
Calculation of a Negative Gap
The negative gap is calculated by subtracting the total of interest-sensitive liabilities from the total of interest-sensitive assets. If the result is negative, the bank has a negative gap.
Impacts on Banks
A negative gap implies that the bank would incur higher payment obligations on its liabilities compared to the returns from its assets if interest rates rise. This situation exposes the bank to interest rate risk.
Implications in Banking
Risk Management
Banks must manage the risks associated with a negative gap proactively:
- Interest Rate Risk: When interest rates rise, the bank may pay more on its liabilities than it earns on its assets, leading to a potential reduction in net interest income.
- Liquidity Risk: A significant negative gap can also create liquidity issues if the bank does not have enough liquid assets to cover its liabilities.
Strategies to Mitigate Negative Gaps
- Asset Repricing: Adjusting the terms of existing loans and investments to better align with current interest rates.
- Liability Management: Seeking longer-term deposits and borrowing arrangements that are less sensitive to immediate changes in interest rates.
Historical Context
The concept of interest rate gaps gained prominence with the increased complexity of financial instruments and interest rate volatility in the late 20th century. The management of interest rate risk became a crucial aspect for banks post the deregulation era of the 1980s.
Applicability and Examples
Real-World Scenarios
- Example 1: A bank has $500 million in loans that are fixed-rate and $600 million in deposits that are variable-rate. If the interest rates increase, the cost of servicing the $600 million deposits will exceed the earnings from the $500 million loans, resulting in a negative gap.
- Example 2: Banks during economic downturns might see more liabilities being interest-sensitive compared to their assets, exposing them to heightened risk.
Comparative Analysis
- Positive Gap: A situation opposite to a negative gap where interest-sensitive assets exceed interest-sensitive liabilities. Positive gaps benefit banks when interest rates rise.
Related Terms
- Duration Gap: The difference in the weighted durations of a bank’s assets and liabilities.
- Repricing Risk: The risk that arises from the timing differences in the re-pricing of assets and liabilities.

Summary
A negative gap in banking indicates that a bank’s interest-sensitive liabilities exceed its interest-sensitive assets, exposing it to potential interest rate risks. Through effective risk management and strategic adjustments, banks can manage and mitigate the associated financial impacts. Understanding negative gaps is crucial for maintaining a stable and healthy financial institution.
