Introduction

A negative gap means a bank or financial institution has more rate sensitive liabilities than rate sensitive assets over a given time period. This makes earnings more vulnerable when interest rates rise because funding costs may increase faster than income from assets.

  • A negative gap exists when rate sensitive liabilities exceed rate sensitive assets.
  • It is commonly measured through gap analysis, a tool used in asset-liability management.
  • Rising interest rates can reduce profitability for institutions with a negative gap.
  • Falling interest rates may benefit institutions with a negative gap because funding costs can decline faster.
  • Banks use asset-liability management strategies to monitor and manage interest rate risk.
  • Interest rate risk is closely linked to the size and duration of the negative gap.

What is a negative gap?

A negative gap is a situation where an organisation's rate sensitive liabilities are greater than its rate sensitive assets within a specific time frame.

Rate sensitive assets are assets whose interest income changes when market interest rates change. Examples include floating-rate loans and short-term investments. Rate sensitive liabilities are obligations whose interest costs change with market rates, such as deposits that mature or reset soon.

Negative gap formula

ComponentMeaning
Rate sensitive assets (RSA)Assets affected by interest rate changes
Rate sensitive liabilities (RSL)Liabilities affected by interest rate changes
GapRSA − RSL

When the result is negative, the institution has a negative gap.

Why does a negative gap matter?

A negative gap directly affects interest rate risk.

If interest rates rise, the cost of liabilities may increase faster than the income earned from assets. This can reduce net interest income and profitability.

If interest rates fall, the institution may benefit because liability costs decline faster than asset yields.

Key impacts include:

  • Higher exposure to rising interest rates
  • Potential reduction in net interest margins
  • Greater need for balance-sheet management
  • Increased focus on funding costs

Negative gap and asset-liability management

Asset-liability management (ALM) helps banks and financial institutions manage mismatches between assets and liabilities.

A negative gap is one of the measures monitored through gap analysis. ALM teams regularly assess how changes in interest rates could affect earnings and liquidity.

Common ALM actions

StrategyPurpose
Increase rate sensitive assetsImprove interest income responsiveness
Reduce rate sensitive liabilitiesLower funding cost sensitivity
Adjust asset maturitiesBetter match liabilities
Use hedging instrumentsReduce interest rate exposure

By actively managing the balance sheet, institutions can reduce the risks associated with a negative gap.

Difference between negative gap and positive gap

Understanding positive gap vs negative gap helps explain how institutions react to interest rate movements.

FeatureNegative GapPositive Gap
RelationshipRSL > RSARSA > RSL
Interest rate increaseUsually unfavourableUsually favourable
Interest rate decreaseUsually favourableUsually unfavourable
Main concernRising funding costsFalling asset yields

A positive gap generally benefits when interest rates rise because asset income adjusts faster than liability costs. A negative gap often experiences the opposite effect.

Frequently asked questions

What does a negative gap mean?

A negative gap means that rate sensitive liabilities exceed rate sensitive assets during a specific period. In banking, this indicates greater exposure to rising interest rates because funding costs can increase faster than interest income. Negative gap analysis is commonly used in asset-liability management to monitor and manage interest rate risk.

Is a negative output gap good?

A negative output gap is different from a negative gap in banking. A negative output gap occurs when an economy produces below its potential output. It may indicate weaker economic activity, lower demand, and unused resources. While it can reduce inflationary pressure, it may also be associated with slower growth and higher unemployment.

How to calculate negative output gap?

You can calculate a negative output gap using the following formula:

Output Gap (%) = [(Actual GDP − Potential GDP) ÷ Potential GDP] × 100

If actual GDP is lower than potential GDP, the result will be negative. For example, if actual GDP is 95 and potential GDP is 100, the output gap is −5%, indicating that the economy is operating below its potential capacity.
