Save US BRT and WTI Spread
BRT is an indicator for the global oil market; WTI the US oil market.
West Texas light, sweet crude oil is of better quality than Brent. The two futures maintained little price difference from 1987 to 2010. The price spread later widened after the US began producing shale oil and banned oil exports. American oil market got oversupplied, plus speculation in the market, so WTI price declined.
