A regrade swap is a financial instrument that allows traders to exchange exposure between different grades or qualities of the same commodity without physical delivery. These swaps enable participants to trade quality differentials and manage risks associated with specific product specifications while maintaining overall commodity exposure.

Regrade swaps are particularly useful in oil markets where different crude grades have varying refining values and price relationships. These instruments help refiners optimize feedstock mix and enable traders to arbitrage quality spreads. Understanding regrade mechanisms helps assess opportunities in commodity quality markets.

Real-world example: A trader enters a regrade swap to pay West Texas Intermediate prices while receiving Brent crude prices, profiting when the Brent-WTI spread widens due to regional supply-demand imbalances or transportation constraints.
