Interest Rate Factors

Factors Determining the Interest Rate on a Loan/Bond:
i (j) = f (IP, RIR, DRPj, LRPj, SCPj, MPj)
Where,
- IP – #Inflation premium – Compensation for expected growth in the consumer price index;
- RIR – #Real interest rate – The required interest rate under zero inflation conditions;
- DRP (j) – #Default risk premium on the j security – Compensation for the probability of failing to pay the principal or interest on time;
- LRP (j) – #Liquidity risk premium on the j security – Compensation for the risk of being unable to sell the bond at the forecasted price quickly and at low costs;
- SCP (j) – Special feature #premium on the j security – Compensation for special features packaged with the bond, such as taxability, convertibility, callability, and other special conditions;
- MP (j) – #Maturity premium on the j security – Compensation for the risk associated with the time remaining until the full repayment of the loan.
