据普氏能源资讯9月4日报道，周三上午，洲际交易所布伦特原油期货和迪拜原油期货之间的价差扩大至两个多月来的新高。因预期美国股市下跌，布伦特原油价格上涨，市场参与者将继续消化阿布扎比最新的官方原油销售价格（OSPs）。

周三上午11点(格林尼治时间03：00)，新加坡布伦特/迪拜期货掉期交易所名义价格为3.21美元/桶。这比周二下午4:30新加坡(格林威治时间08：30)评估的3.17美元/桶上涨了4美分/桶。

新加坡时间周三上午11点，洲际交易所11月期布伦特原油期货从周二结算价上涨22美分，至58.48美元/桶，价差进一步扩大。布伦特原油价格上涨，原因是炼油商维持高企的供应，市场预期，上周美国原油库存将下降。

标普全球数据显示，布伦特/迪拜原油价差在6月18日被评估为3.29美元/桶后，继续走高。这提高了迪拜原油对布伦特原油的竞争力。

周三上午迪拜期货息差与周二的评估结果基本持平。

10月/ 11月迪拜原油期货价差周三在新加坡上午11：00(格林威治时间03：00)收于0.73美元/桶，11月/ 12月迪拜原油期货价差收于0.69美元/桶。而在周二，这两个价差分别为70美分/桶和69美分/桶。与此同时，市场参与者正在消化阿布扎比国家石油公司(ADNOC)周二晚间发布的8月份原油等级，即Murban、Umm Lulu、Das Blend和Upper Zakum。

虽然OSPs较7月有所下降，但这四个等级与迪拜的OSPs差值提高了14美分/桶至34美分/桶。本周早些时候，市场参与者曾预计，ADNOC将把4个等级的价差逐月提高10至20美分/桶，这反映出8月份的现货交易水平。

Brent/Dubai EFS widens to over 2-month high

The spread between ICE Brent futures and Dubai crude futures widened to over a two-month high mid-morning Wednesday in Asia, as Brent rose on expectations of US stocks draw, while market participants continued to digest the latest Abu Dhabi's official crude selling prices.

The Brent/Dubai Exchange of Futures for swaps was notionally pegged at $3.21/b, at 11 am in Singapore (0300 GMT) Wednesday. This was up 4 cents/b from the $3.17/b assessed at 4:30 pm in Singapore (0830 GMT) Tuesday.

The spreads have widened as the front-month ICE Brent November futures rose 22 cents/b from Tuesday's settle to $58.48/b at 11 am in Singapore (0300 GMT) Wednesday.

Brent rose amid expectations of a drop in US crude inventories last week as refiners maintained high runs.

The Brent/Dubai EFS was last wider on June 18 when it was assessed at $3.29/b, S&P Global Platts data showed. A wider spread increases the competitiveness of Dubai-linked crude oil versus Brent-linked crude oil.

The Dubai futures intermonth spreads remained mostly unchanged Wednesday morning from Tuesday's assessments.

The October/November Dubai futures spread was pegged at 73 cents/b, while the November/December Dubai futures spread was pegged at 69 cents/b at 11 am in Singapore (0300 GMT) on Wednesday.

These compared to 70 cents/b and 69 cents/b assessments for the two respective spreads on Tuesday.

Meanwhile, market participants were digesting Abu Dhabi National Oil Company (ADNOC) OSPs for its August-loading crude oil grades, namely Murban, Umm Lulu, Das Blend and Upper Zakum, which it released late Tuesday.

While the OSPs were lower compared to July, the OSP differentials of the four grades to Dubai were raised by between 14 cents/b to 34 cents/b.

Market participants surveyed by Platts earlier this week had expected ADNOC to raise the price differentials of the four grades by 10 to 20 cents/b month on month, in reflection of spot trading levels over August.
