Lending businesses face multiple risks; one of them is interest rate risk, which is losses occurring due to adverse interest rate changes. The increased volatility amid unprecedented situations forces financial institutions to recognise the importance of liquidity management in controlling interest rate risk.
Various approaches measure lending businesses’ exposure to interest rate risk. Among the simplest are the duration gap analysis and repricing gap analysis. Both methods give insights into interest rate sensitivity to ensure efficient asset-liability management.
This article will help you solve the dilemma of the usability of the duration gap and repricing analysis to their best suitability.
What is Duration Gap Analysis?
First, we have to understand what duration means here. Duration is the weighted average time for the arrival of cash flows. It indicates how long it will take to receive or repay the cash flows linked to an asset or liability.
Duration gap analysis is a methodology that compares the durations of assets and liabilities of financial institutions and determines the sensitivity of the net worth to changes in interest rates.
Duration gap analysis captures three effects mainly:
- Leverage-adjusted duration gap.
- Size of financial institution (total assets).
- Size of the interest rate shock.
For instance, in the case of a positive duration gap, the duration of assets is longer as shorter-term liabilities are funded with longer-term assets. A rise in interest rates could lead to potential losses in market value. Conversely, a negative duration gap suggests vulnerability to falling rates.
Using the analysis, a lending business can reduce its risk exposure by adjusting the asset-liability duration and composition. For example, they can match the duration of their assets and liabilities or diversify their asset portfolio to reduce the impact of interest rate changes.
Strengths
Duration gap analysis offers several advantages:
- Holistic risk assessment: Helps lenders assess default risk in loan portfolios by considering both timing and amount of cash flows.
- Better financial gains: Maturity management can reduce risk exposure, improving overall financial health.
- Informed decision-making: The analysis provides actionable insights into different scenarios that can be utilised in efficient portfolio management.
Weaknesses
Critics of duration gap analysis argue that:
- Costly and high complexity: The analysis involves balance sheet restructuring, complex calculations, and assumptions that limit accessibility for smaller institutions that don’t have sophisticated tools.
- Changes in cash flows: Duration gap analysis is designed for fixed cash flows over time and doesn’t account for the high variability. This can lead to inaccuracies in the analysis.
What is Repricing Gap Analysis?
The repricing gap measures how quickly the interest rates on a bank’s assets and liabilities can change. Also known as the funding gap model, it focuses on the difference between the interest income earned and interest paid on assets and liabilities, respectively, over a given repricing time period.
Now, repricing time period means the time taken by assets or liabilities to adjust their interest rate changes to reflect market rates.
Repricing gap analysis quantifies the difference between rate-sensitive assets (RSAs) and liabilities (RSLs). A positive gap indicates a higher holding of RSAs than RSLs. Therefore, the bank’s assets will reprice upward faster, increasing net interest income in response to the rise in interest rates.
For instance, a bank can use repricing gap analysis to determine the most vulnerable period to interest rate changes and their impact on its earnings.
Strengths
Repricing gap analysis offers several advantages:
- Less complex and economical: It is suitable for smaller institutions with limited resources. Its simple calculations require less data, making it a practical choice for these institutions.
- Provide a comprehensive view of short-term interest rate risk: Offers multiple time buckets (one day, one day to three months, etc.), which allows for better measurement of sensitivity in smaller time-frames.
Weaknesses
There are many lacunas in the repricing gap analysis applicability:
- Overlooks market value effects: The analysis mainly includes only book value. However, interest rate changes can adversely affect the market value of assets and liabilities. Thus, the repricing model is only a partial measure of interest rate risk.
- Over-aggregation: Rate-sensitive assets and liabilities might not be evenly distributed within a maturity bucket.
- Theoretical assumptions in analysis: In real scenarios, the interest rate changes are not uniform across all assets and liabilities.
What is the Suitable Analysis Method for Your Lending Business?
Both the gap analysis models can be used to measure interest risk exposures in lending businesses; however, the applicability of the model will depend upon a number of factors:
- Time Horizon: Long-term risks vs. short-term risks.
- Complexity and size of institution: Availability of expertise and tools.
- Risk management goals: Long-term stability vs. short-term liquidity.
Scenario to Choose Duration Gap Analysis
Duration gap analysis must be chosen when a financial institution wants to analyse long-term risks. It has sophisticated tools for complex analysis requiring detailed data inputs on the timing of cash flows and sensitivity to interest rate changes.
For example, it is helpful for mortgage portfolios.
When Should You Choose Repricing Gap Analysis
Suppose a small institution wants to analyse interest risks in short-term loans. In that case, the repricing gap analysis is a better option. On monitoring the assets and liabilities in different repricing intervals, one can find a balanced gap to manage interest rate changes swiftly in times of volatility.
For example, credit unions providing consumer loans can use this model.
However, combining both models would provide a better and more comprehensive risk management strategy for a lending business with a combination of short-term and long-term assets.
The Takeaway
Managing interest rate risks is a crucial component of risk management strategy. Leveraging duration gap and repricing analysis models as per their applicability would strengthen the stability of lending businesses.
