据世界石油网8月6日华盛顿报道，美国能源信息署(EIA)在其最新一期的《能源展望》（STEO）报告中预测，布伦特原油和西德克萨斯中质原油之间的价差在今年剩余时间和2020年将收窄。

EIA预计，在今年第4季度和2020年，WTI原油的平均价格将比布伦特原油价格每桶低5.5美元，这比7月份的每桶6.60美元的价差有所收窄。

价差收窄反映了EIA此前的假设，即从二叠纪盆地到美国墨西哥湾沿岸炼油厂和出口终端的原油管道运输限制将在未来几个月里得到缓解。

在7月份的STEO报告中，EIA预测布伦特-西德克萨斯中质原油2020年的平均价差为4美元/桶。最新的差价预测反映了EIA对通过管道将原油从俄克拉荷马州库欣运往墨西哥湾沿岸地区的边际成本修改后的假设。

EIA forecasts narrowing Brent, WTI spread on reduced pipeline constraints

In its current Short Term Energy Outlook, the U.S. Energy Information Administration anticipates a narrower differential between Brent and WTI crude prices for the rest of the year and into 2020.

EIA expects West Texas Intermediate crude oil prices will average $5.50/bbl less than Brent prices during the fourth quarter of 2019 and in 2020, narrowing from the $6.60/bbl spread during July. The narrowing spread reflects EIA’s assumption that crude oil pipeline transportation constraints from the Permian basin to refineries and export terminals on the U.S. Gulf Coast will ease in the coming months. In the July STEO, EIA forecast the Brent-WTI spread to average $4.00/bbl in 2020. The updated differential forecast reflects EIA’s revised assumptions about the marginal cost of moving crude oil via pipeline from Cushing, Oklahoma, to the Gulf Coast.
