What is the primary purpose of a commodity swap?

The primary purpose of a commodity swap is to exchange floating commodity prices, making this the correct choice. In a commodity swap, two parties agree to exchange cash flows related to the prices of specific commodities. One party typically pays cash flows based on a fixed price for the commodity while receiving payments based on a floating market price. This mechanism allows businesses to manage their exposure to price fluctuations in commodities, providing a way to stabilize costs or revenues associated with those commodities over time.

The other options do not align with the fundamental operations of commodity swaps. Hedging against currency fluctuations pertains to currency swaps rather than commodities. Converting debt obligations into equity involves different financial instruments such as convertible bonds and does not directly relate to commodity pricing. Securing fixed interest rates on loans typically refers to interest rate swaps, which involve exchanging fixed and floating interest payments, not commodity prices.
