Definition
An index swap is a financial contract in which two parties exchange cash flows based on predetermined criteria, which is often linked to a specified index such as a debt or equity price index. One party pays a fixed cash-flow while receiving a varying payment linked to the performance of the index, and vice versa.
An overnight index swap (OIS) is a specific type of index swap that involves payments based on an overnight interest rate, particularly prevalent in contexts where the Federal Funds Rate is utilized, allowing for the management of interest rate exposure in the short term.
| Feature | Index Swap | Overnight Index Swap (OIS) |
|---|---|---|
| Duration | Versatile (3 months to over 1 year) | Short-term (typically around 1 year) |
| Cash Flow | Could involve fixed or floating | Primarily based on overnight rate |
| Interest Calculation | Fixed payouts on one leg | Rate compounded overnight |
| Purpose | Hedging against index fluctuations | Short-term interest rate risk management |
Example
Let’s say Party A agrees to pay Party B a fixed cash flow based on an index while receiving cash flows based on a floating rate determined by an index (like the S&P 500). If the index performs well, Party B benefits more than if Party A simply held the underlying asset directly.
