Facts citing this source

  • Brent and WTI are the two most-watched crude oil benchmarks; the Brent–WTI spread reflects differences between waterborne international crude and U.S. landlocked crude. Warconomy tracks them as market benchmarks alongside conflict and chokepoint risk, not as causal attributions.
