Duration matching is a risk management strategy (or "asset-liability management" technique) used by financial institutions, such as insurance companies and banks, to mitigate interest rate risk by aligning the duration of assets with the duration of liabilities. It works by ensuring that the sensitivity of a portfolio's assets to interest rate changes mirrors that of its liabilities, theoretically immunizing the portfolio against price changes caused by parallel shifts in the yield curve.
Duration matching is a risk management strategy, commonly used in the insurance industry, where the duration (price sensitivity to a yield curve movement) of an asset portfolio is adjusted to be made equal to the duration of the liability. This is done under that assumption that doing so eliminates interest risk.
Duration is a measurement of a bond's interest rate risk that considers a bond's maturity, yield, coupon and call features. These many factors are calculated into one number that measures how sensitive a bond's value may be to interest rate changes.
Duration mismatch refers to a situation where a financial institution borrows short-term funds to lend long-term loans, creating a gap between its assets and liabilities.
Duration gap analysis is a risk management tool that measures the difference between the durations of a financial institution's assets and liabilities. It helps assess how changes in interest rates will affect the institution's net worth. This analysis focuses on three key variables: Leverage-adjusted duration gap.
There are four types of structural interest rate risk. As defined in the Basel paper, the four risks are repricing (mismatch), yield curve, basis and optionality. Repricing or mismatch risk is created when fixed rate loans are funded by variable rate borrowings or when fixed rate deposits fund variable rate loans.
Generally, the higher a bond's duration, the more its value will fall as interest rates rise, because when rates go up, bond values fall and vice versa.
Types of Interest Rate Risk
Mismatch Risk: Happens when assets (like loans) and liabilities (like deposits) don't reprice at the same time. For example, if an institution holds long-term fixed-rate loans but has to frequently reprice short-term deposits, it might earn less as rates rise.
Duration analysis provides a comprehensive measure of interest rate risk for the total portfolio. Duration analysis considers the time value of money and is additive in nature, thereby enabling banks to match their total assets and liabilities rather than matching individual accounts.
Duration assumes a linear relationship between bond prices and changes in interest rates. In actuality, however, prices fall at an increasing rate as interest rates rise; similarly, prices rise at an increasing rate as interest rates fall.
There are three types of bond durations namely, Macaulay duration, modified duration and effective duration. A Macaulay duration represents the weighted average time before a bond's cash flows are fully paid and provides an effective way of measuring the time until an investor will get their money back.
Interest rate risk refers to the potential for a decrease in the value of an asset due to unexpected changes in interest rates. This risk is particularly significant for fixed-income securities, such as bonds, where fluctuations in interest rates can directly impact the asset's price.
Meanwhile, duration measures a bond's sensitivity to interest rate changes, and reflects the weighted average time it takes to receive all cash flows from the bond. While maturity essentially tells you when you get your money back, duration is used to determine how much risk is involved with interest rate changes.

The four main types of financial risk are Market Risk, Credit Risk, Liquidity Risk, and Operational Risk, representing potential losses from market changes, borrower defaults, inability to meet obligations, and internal failures, respectively, though other categories like legal/regulatory or inflation risk are also recognized.
Duration mismatch
If the liabilities become due before the assets, then the bank may be unable to satisfy its obligations. As a result, it may be forced to liquidate some of its assets (perhaps at a loss) or raise additional capital (which may be dilutive or otherwise costly).
In some cases, you may need to submit documentation to back up your position, such as written evidence of lower rates being offered by competing lenders before your bank may be willing to match or beat it.
A well-known maxim of bond investing is that when interest rates fall, bond prices rise, and vice versa. This is also referred to as interest rate risk. And some bonds are more sensitive to interest rate changes than others. That sensitivity is known as a bond's duration.
Duration is a way of measuring the interest rate risk of an individual or portfolio of fixed income securities. Pure, or Macaulay duration, is calculated by discounting all cash flows of a bond using the proper interest rate and then time weighting each of the cash flows.
Investors holding a high duration bond need to wait longer for the bond's value to be repaid. But over a longer timeline, it is more likely that interest rates will rise, which means there is a higher likelihood that the bond's value will decline.
