Key Market Spreads & Arbitrage Matrix
Compare published differences between named markets, products and contracts. Each spread retains its own unit, tenor and observation date; a positive or negative value describes that relationship rather than a complete delivered trading margin.

Reading spreads consistently
A spread is a difference between the named assessments or contracts. Preserve the published sign: a negative reading means the first leg is below the second under the source convention. A change in a spread is not the percentage change of either commodity.
Compare the same tenor and unit. Balance-of-month and M1 are different periods; USD/bbl and USD/mt require a product-specific conversion before comparison. The tables reproduce published spread assessments and do not independently reconstruct unspecified legs.
Each row carries its observation date. Updates from different reports need not be simultaneous. A quoted spread alone does not establish a tradable arbitrage after freight, financing, taxes and handling costs. See the linked series for the available history and unresolved contract specifications.
