Oil prices slipped by the end of the week – Weekly recap 6-9 September

Crude oil prices started the week strong, but by the end of the week as the US stock markets declined – the S&P500 index lost 0.94% of its value during the week – crude oil prices followed and declined as well. The appreciation of the US dollar throughout the week against the Euro and CAD also helped oil prices to drop; the ECB’s decision to keep Euro Area interest rate unchanged helped the Euro to depreciate against the USD; the BOC also kept its overnight rate at 1%; the CAD also depreciated against the USD. The weather disruptions in the US may affect its oil production in the Gulf of Mexico and may have a long term effect on the US’s oil supply; in the mean time the oil stockpiles declined during the week. By the end of the week, Brent oil price slightly fell by 0.93% while WTI spot oil inclined by 1.45%; as a result, the spread between Brent oil and WTI oil reached $25/b on Friday. 

 Let’s review the changes during last week (September 6th to September 9th) of crude oil prices (Brent oil and WTI), and present a summary of the recent EIA petroleum report:
