About the Overnight Index Swap:
- It is a derivative instrument where returns under a fixed-rate asset are swapped against a predetermined 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 loans.
- Typically, 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 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.
