What is Interest Rate Risk :
Interest rate risk is the risk where changes in market interest rates might adversely affect a bank’s financial condition. The management of Interest Rate Risk should be one of the critical components of market risk management in banks. The regulatory restrictions in the past had greatly reduced many of the risks in the banking system. Deregulation of interest rates has, however, exposed them to the adverse impacts of interest rate risk.
What is the Impact of IRR: The immediate impact of changes in interest rates is on the Net Interest Income (NII). A long term impact of changing interest rates is on the bank’s networth since the economic value of a bank’s assets, liabilities and off-balance sheet positions get affected due to variation in market interest rates.
The Net Interest Income (NII) or Net Interest Margin (NIM) of banks is dependent on the movements of interest rates. Any mismatches in the cash flows (fixed assets or liabilities) or repricing dates (floating assets or liabilities), expose bank’s NII or NIM to variations. The earning of assets and the cost of liabilities are closely related to market interest rate volatility.
The interest rate risk when viewed from these two perspectives is known as ‘earnings perspective’ and ‘economic value’ perspective, respectively.
Management of interest rate risk aims at capturing the risks arising from the maturity and repricing mismatches and is measured both from the earnings and economic value perspective. (a) Earnings perspective involves analysing the impact of changes in interest rates on accrual or reported earnings in the near term. This is measured by measuring the changes in the Net Interest Income (NII) or Net Interest Margin (NIM) i.e. the difference between the total interest income and the total interest expense. (b) Economic Value perspective involves analysing the changes of impact og interest on the expected
