据普氏能源资讯8月7日休斯顿报道，上周美国原油出口跌到了2018年10月以来的最低水平，原因是套利经济已经收紧以及对需求放缓的担忧加剧。

在出口放缓之际，由于供应以及把二叠纪原油生产和美国墨西哥湾地区连接起来的管道产能的不断增加，美国原油出口预计将出现增长。

美国能源信息署(EIA)的统计数据显示，在截至8月2日的一周内，美国原油日出口量平均为186.5万桶，比前一周减少了70多万桶，比今年迄今的平均水平低了近100万桶。

在6月份原油日平均出口330万桶以后，美国原油出口量在过去几周已开始减少，4周移动平均日出口量比前两周减少了40万桶。

US crude exports tumble on tighter arbs, demand worries

US crude oil exports fell to the lowest level since October 2018 last week, as arbitrage economics have tightened, and on heightened concerns of a slowdown in demand.

The slowdown comes amid an expected ramp up in exports driven by rising supply and pipeline capacity linking Permian crude production to the US Gulf.

US crude exports averaged 1.865 million b/d in the week ending August 2, down over 700,000 b/d week on week, and nearly 1 million b/d lower than the year-to-date average, according to data from the Energy Information Administration.

After averaging around 3.3 million b/d in June, US exports have begun to taper off over the past few weeks, with the 4 week moving average of US exports falling 400,000 b/d from just two weeks prior.
