Interest Rate for Government Bonds – Logic behind Interest Rate

What is Interest Rate for Government Bonds?


When a government of India issues the bonds it will generally make regular interest payments during the life of the Gov Bond and repay the initial investment, or principal amount, when the bonds expire on their ‘maturity date’.
Generally, short-term bonds are known as Treasury Bills in India with a maturity of less than one year.
T-bills are available with different maturity periods ranging from 91 days to 365 days.
On the other side, bonds with a maturity of more than a year, ranging from 5 to 40 years are long-term securities knows as Government Bonds (i.e. Dated Securities).

Interest Rate for Treasury Bill


Treasury Bill do not carry an interest component. Actually, this is the main difference between T-bills and Bonds.
In other words, these bills are zero coupon securities and pay no interest. Instead, they are issued at a discount and redeemed at the face value at maturity.
These bills are issued at a discount to their PAR i.e. Par value (also called the true value), and upon expiry, it’s redeemed at its true value.

Let’s take an example to understand the calculation of discount value in a better manner.
For instance, assume the Par Value, is INR 100/-. This T-bill is issued in person at a discount to its PAR, Say INR 96/-. After 91 days, person will get back INR 100/-, and so person makes a return of INR 4/-.
In other word, this is as good as buying a stock at INR 96/- and selling it after 91 days at INR 100/-.
The only difference is that this is a guaranteed transaction, meaning, there is no risk of you selling below INR 100/- (or above INR 100/-).

Considering the same details as above, let us know the exact formula of Treasury Bills rate.

The formula is –

Y = (D/P)*(365/N)

Y = Yield
D = Discount Value
P = Bond Price
N = Number of days to maturity

Y = [4/96]*[365/91] = (0.041)*(4.01) =16.7%

Therefore, the treasury bill offers a return on investment of 16.7%. However, since you held it for 91 days, you will enjoy this return on a pro-rata basis.

Logically, 91-day yields are around 6-8%. Needless to say, the higher the yield, the better it is.

Here’s what you need to know about the Dated Securities rates.

RBI Bonds or Government of India Savings (Taxable) Bonds

Though, investors should note that the term of NSCs is 5 years compared to 7 years on the RBI Bonds.

For example, the prevailing NSC rate is 6.8%. Now adding another .35% to the NSC rate, i.e. 6.8% + .35% = 7.15%, the interest rate for the RBI Bonds he interest rate (payable on July 1, 2021) was decided.
