Oil prices end the week with a noticeable decline - investors are playing up the strengthening of the US trade rhetoric. New duties proposed by Donald Trump are causing concerns about the prospects of global demand. Oil is losing positions, and short-term traders are forced to withdraw from buy deals amid a sharp collapse of quotes after the previous growth. At the same time, fundamental factors - including the level of OPEC+ production and instability in the Middle East - remain in the center of attention.The sharp decline in prices originates from the level of $72.20, which we wrote about a few days ago. Now the price is back within the global support zone.
