According to the market, the crude oil future price on November 5th had faced a 4-day first decline, mainly because of the worsening epidemic of Covid-19 in the world.

Among them, the market worried many of the countries would re-levy the lockdown policy to prevent the expansion of Covid-19, which might further pressure the crude oil demand.

Moreover, the crude oil future price for December in the West Texas Intermediate was US$38.79/barrel on November 5th, and the future crude oil price for next January in the Brent crude was US$40.93/barrel, both dropped within 1% from the previous day.
