Management Notes

**Market Interest Rate**

Market Interest Rate is the rate of interest paid on deposits and other investments, determined by the interaction of the supply of and demand for funds in the money market. This interest rate is offered most commonly on deposits in banks, other interest-bearing accounts, as well as on loans. The market interest rate is different for different investment vehicles, though all are determined by the supply and demand for credit.

**Determinants of Market Interest Rate**

The factors affecting the interest rates are called determinants of the interest rate. The market interest rate is the function of many factors including the real cost of money, inflation, risk, etc. There are the different determinant of market interest rate which are as follows:

Market Interest Rate ( K)= K* + IP + DRP + LRP +MRP

where,

- K* = Real Risk-Free Rate of interest
- IP = Interest Premium
- DRP= Default Risk Premium
- LRP= Liquidity Risk Premium
- MRP= Market Risk Premium

**Real Risk-Free Rate of interest (K* )**

Real Risk-Free Rate is defined as the interest rate that would exist on riskless security if no inflation were expected or when inflation is zero. In other words, it is the rate of interest from riskless government securities in the absence of inflation but this real rate of interest is never seen in the economy because inflation is never expected.

**Nominal Risk-free rate**

The nominal rate is defined as the actual rate of interest charged by the supplier of funds and paid by the demander of funds and it is always composed of the real risk-free rate of interest and premium of inflation.ie;

OK1 = K* + IP1/1

OK2 = K* + (IP1+IP2)/2

OK3 = K* + (IP1+IP2+IP3)/3

**Default Risk Premium (DRP) **

The default Risk premium is the risk that a borrower will default on a loan which means not pay the interest or the principal. Higher the default risk higher will be the interest rate and vice-versa.

K= K* + IP + DRP

Where , IP = Interest Premium , DRP= Default Risk Premium

Note: In Government Purposed Security, DRP=0

**Liquidity Risk Premium (LRP) **

Liquidity Risk Premium is the premium charged for taking the risk on security with a weak liquidity risk premium.

K = K* + IP +DRP +LRP

**Maturity Risk Premium (MRP) **

Maturity Risk Premium is the premium charged by the investor for capital losses due to the changes in the market interest rate.

K = K* + IP +DRP +LRP+MRP

An interesting discussion is definitely worth comment. There’s no doubt that that you need to publish more on this subject matter, it may not be a taboo subject but generally people don’t discuss such subjects. To the next! Many thanks!!

thank you 🙂
