How to Trade Oil

Easing US Yields, USD and EIA Storage Data Help Oil Recover Losses

Greater than expected US crude drawdowns helped reverse selling in the US session yesterday, extending early gains that followed from lower US treasury yields and a weaker US dollar. Terrible EU and UK PMI data worsened the economic outlook which typically precedes pessimism around global growth and ultimately oil demand growth of which China is anticipated to contribute 60% of that increase. Therefore, oil markets may continue to react strongly to negative Chinese data as it trickles through.

The daily Brent crude chart tells the story of shorter-term downward direction that has shown signs of fatigue ahead of the $82 level. Yesterday and thus far today, prices reveal an extended lower wick – suggesting a rejection of lower prices for now. However, given that the dollar, while marginally softer, remains resilient as US data tends to outperform estimates. A strong dollar and deteriorating outlook could lead to knee-jerk selling particularly if next week’s Chinese manufacturing PMI data disappoints further. $82 then becomes the focus followed by the 200-day simple moving average. On the upside, the recent spike high around $86 comes in as resistance.

The weekly chart shows oil’s tendency to trade within the defined trading range between $71.50 and $89, frequently testing the lower bound throughout April and June this year. $89 is once again instrumental in capping oil prices despite tighter supply – witnessed by the touch and run exhibited via the weekly doji candle. Subsequent selling has ensued and we’re on track for a second week of lower prices. The longer-term outlook suggests oil prices may rise again towards $89 if the dollar, yields remain elevated alongside worsening Chinese and European economic data which naturally leads to concerns around global growth and oil demand.
