There is complete deregulation of Interest rates on Fixed Deposits, Recurring Deposits, and SB
Deposits above Rs. 1.00 lac. Banks are also free to determine Interest rates on NRE Deposit
accounts. This has led to interest rate Volatility resulting into greater Interest Rate Risk.
Adverse movement of Interest rates has direct impact on NII as well as NIM. Market Interest
rate also has impact on Present Value of Bonds and Securities. 1% rise in market rate of return
will cause lesser valuation of securities. Also 1% fall in interest rate will cause higher valuation
of securities resulting into increase in Mark to Market Price.
Types of Interest Rate Risk
Following are various types of Interest Rate Risk:
1. Mismatch or Gap Risk
This is risk of gap between maturities of Assets and Liabilities. Sometimes, Long term
loans are funded by short term deposits. After maturity of deposits, these liabilities are
get repriced and Gap of Interest rates between Assets and Liabilities may become
narrowed thereby leading to reduction of profits.
2. Basis Risk
Change of Interest rates on Assets and Liabilities may change in different magnitudes
thus creating variation in Net Interest Income. It tries to explain what will be the %age
effect on Earnings due to increase or decrease in interest rates by 1bps.
3. Net Interest Position Risk
If the bank has more assets than the liabilities, 1% decrease in interest rate will result
into less earnings and more expenditure on account of interest. This will directly affect
NII and NIM.
4. Embedded Option Risk
Adverse movement of Interest Rate may result into pre-payment of CC/DL and TL. It
may also result into pre-mature withdrawal of TDs/RDs. This will also result into reduced
NII. This is called Embedded Risk.
5. Yield Curve Risk
Yield is Internal Rate of Return on Securities. Higher Interest Rate scenario will reduce
Yield and thereby reduction in the value of assets. Adverse movement of yield will
certainly affect NII (Net Interest Income).
6. Price Risk
In financial market, when assets are sold before maturity in order to meet liquidity
requirements, loss may occur due to lower selling price.
7. Re-investment Risk
It is uncertainty with regard to interest rate at which future cash flows could be reinvested.
