Recently, Indian overnight index swap (OIS) rates rose to their highest levels in 10 months due to offshore paying and triggering of stop losses.

About Overnight Index Swap:

  • It is a derivative instrument where returns under a fixed rate asset are swapped against a pre-determined published index of a daily overnight reference rate for an agreed period of time.
  • The primary purpose of an OIS is to manage interest rate risk, particularly the risk associated with fluctuations in the overnight lending rate.
  • An overnight index swap rate is calculated each day.
  • This rate is based on the average interest rate institutions with loans based on the overnight rate have paid for that day.


How does an OIS work?

  • These are instruments that allow financial institutions to swap the interest rates they are paying without having to refinance or change the terms of their existing loan.
  • , when two financial institutions create an overnight index swap, one of the institutions is swapping an overnight (floating) interest rate and the other institution is swapping a fixed short-term interest rate.
  • To get the swap rolling, both the firms would agree to continue servicing their loans, but at the end of a specified time period whoever ends up paying less interest will make up the difference to the other firm.


What is a derivative?

  • It refers to a type of financial contract whose value is dependent on an underlying asset, group of assets, or benchmark. 
  • Common derivatives include futures contracts, forwards, options, and swaps.
