据普氏能源资讯7月30日新加坡报道，周二，洲际交易所迪拜基准原油期货与布伦特原有期货价差扩大。此前有预测，美国原油库存将下降和伊朗石油出口也将大幅下降，因此，布伦特原油在纽约商品交易所上涨强度下降。而迪拜原油期货交易量稀少,中东高硫原油交易也不活跃。

新加坡时间上午11点(格林尼治时间03：00)， 9月份，布伦特/迪拜期货交易所掉期价格值为2.23美元/桶，高于周一亚洲市场收盘时的2.12美元/桶。

随着全球原油价格走高，9月份迪拜原油期货于周二上午上涨至61.75美元/桶，但涨幅滞后。周一晚间，迪拜9月份石油价格为每桶60.92美元。普氏能源资讯数据显示，9月洲际交易所布伦特原油期货从每桶63.04美元攀升至每桶63.98美元。

标普全球分析师表示，截至7月26日的一周，美国商业原油库存预计将减少390万桶，至4.411亿桶。与此同时，在9月的最后两个交易日，含硫原油的交易活动似乎较为清淡，交易员将注意力转向了10月份的波斯湾原油进口。

据市场传言，亚洲炼油商从霍尔木兹海峡(Strait of Hormuz)或周边地区增产的计划没有发生重大变化。

据普氏贸易软件cFlow数据显示，今年6月，伊朗石油进口量从5月的约90.11万桶/天和2018年6月的约250万桶/天降至约44.86万桶/天，2019年下半年，伊朗的日均出口量将达到40万至45万桶，低于上半年的150万桶。

Brent/Dubai spread widens as September trading slows

Benchmark Dubai crude futures' discount to ICE Brent widened Tuesday morning in Asia, as Brent and NYMEX futures gained strength on expectations of a drop in US crude stocks and a sharp decline in Iranian oil exports, while the Dubai end of the spread was lackluster amid sparse trading activity for Middle East sour crude.

At 11 am in Singapore (0300 GMT), the September Brent/Dubai Exchange of Futures for Swaps spread was notionally assessed at $2.23/b, rising from $2.12/b assessed at the close of trading in Asia on Monday.

September Dubai futures were up at $61.75/b Tuesday morning following the global crude complex higher, but was lagging the rise. September Dubai was assessed at $60.92/b Monday evening.

September ICE Brent futures climbed from $63.04/b to $63.98/b during the same period, Platts data showed.

US commercial crude inventories for the week ended July 26 are expected to fall by 3.9 million barrels to 441.1 million barrels, according to analysts surveyed Monday by S&P Global Platts.

Meanwhile, trading activity for sour crude barrels looked muted for the last two trading days of the September cycle, while traders turn their focus onto expectations for October-loading volumes from the Persian Gulf.

Market talk indicated that there was no significant changes in Asian refiners' plans to lift barrels from or around the Strait of Hormuz.

According to data from Platts trade flow software cFlow, shipments of Iranian oil fell to about 448,600 b/d in June from about 901,100 b/d in May and about 2.5 million b/d in June 2018.

Platts Analytics expects Iranian exports to average 400,000-450,000 b/d in the second half of 2019, down from 1.5 million b/d in the first half.
