The number of active oil drilling in the United States has dropped sharply, the demand for crude oil is strong, and the dollar is weakening, which has boosted the upward momentum of oil prices. Last Friday (September 15), the electronic price of US WTI 10 crude oil futures closed up by 0. 1 1 USD, or 0.22%, to 49.83 USD/barrel. The electronic price of ice Brent 165438+ 10 crude oil futures closed up 0.20 USD, or 0.36%, to 55.48 USD/barrel. The ruble is at arm's length from the oil price, sometimes fluctuating with the oil price, and sometimes operating independently of the oil price. Because other influencing factors have not changed much, it is expected to fluctuate with oil prices today. Recently, due to the favorable IEA monthly report, the demand in Europe and the United States is strong, the output of OPEC and non-OPEC has declined, and the oversupply situation is decreasing. The US crude oil once broke through to around 50.4. The number of drilling wells in the United States announced last Friday dropped by 7 to 749, the lowest since June. Coupled with the resumption of work in refineries that were previously shut down due to hurricanes, it is good for oil prices. Recently, although API and EIA data are bad for oil prices, other aspects are good for oil prices. Technically, oil prices are still bullish. After stepping back on the 49.4 line on Friday to confirm the support, it soared above $50 again. Therefore, from the technical and news point of view, oil prices are bullish, but it is necessary to focus on the resistance of 50 and 50.4, especially the 50.4 line, which has repeatedly suppressed oil prices. If we can't effectively break through here in the short term, the probability of short-term callback is high, but the overall trend is still on the rise. It is possible for bulls to launch a second counterattack after the callback, effectively breaking through 50.4. Investors are also worried about the further impact on crude oil demand caused by the resumption of production by American refineries after the hurricane interrupted production.
