Understanding the working of swaps helps demystify how institutions manage risk and cash flows:
Two counterparties enter into a swap contract with predefined terms. One party agrees to pay a fixed rate, while the other pays a floating rate, or both may exchange payments in different currencies. The agreement is based on a notional principal — an amount used to calculate payments, but not actually exchanged. Payments are settled periodically, based on agreed terms.
For instance, a firm with a floating-rate loan might enter a swap to pay a fixed rate instead, locking its interest payments and reducing exposure to interest rate fluctuations.
