Brent oil prices were put under pressure by the news that President Biden's administration in the USA is preparing to make a new move of 10-15 million barrels from strategic reserves within the scope of the 180 million barrel market intervention program that started in the spring. In addition, the decrease in natural gas prices to 115 euros in Europe also has an effect here. Technically speaking, if brent oil, which broke the minor uptrend and headed for a downtrend, goes down below the 89.50 level with permanent closes, the regression may last until the 88.40 support, which will be the 2-week low. In possible upside attempts, 91.85 resistance can be followed closely.
