What is Floating Rate Note (FRN)?
A Floating Rate Note (FRN) is a debt instrument or a bond that gives variable interest rather than a fixed rate. The interest rate is revised periodically against a benchmark rate, such as LIBOR, SOFR, or MIBOR in India.
Purpose
FRNs are designed to:
-
Protect investors against rising interest rates
-
Provide flexible returns that move with the market
-
Help companies or governments borrow money at competitive rates
How It Works?
-
The bond’s interest (also called the coupon) is reset at regular intervals (e.g., every 3 or 6 months).
-
The new rate is usually calculated as:
Benchmark Rate + Spread
(Spread is a small extra percentage to reward investors.) -
So, if the benchmark goes up, your interest earnings go up too.
