Crude oil: on April 28, the price of international crude oil futures closed up, with an obvious increase. The settlement price of the main contract of WTI crude oil futures in the United States was US $105.36/barrel, up US $3.34 or 3.3%; The settlement price of the main contract of Brent crude oil futures was US $107.26/barrel, up US $2.31 or 2.2%. The main reason was that there were rumors in the market that Germany joined the ranks of other EU Member States and the possibility of imposing an embargo on Russian oil increased, which exacerbated the market’s concerns about the expectation of tightening supply in the future.

 

Oil prices rose for three consecutive times this week. According to the monitoring of business news agency, WTI rose by 6.92% and Brent crude oil rose by 4.99%. Earlier, the US Energy Information Administration (EIA) report released on Wednesday showed that the growth of US commercial crude oil inventories was lower than expected.

The crude benzene market fluctuated this month. At the beginning of the month, the price fluctuated slightly between 6660-6800, and at the end of the month, the price rose first and then fell. In the first half of the month, affected by the wide-ranging fluctuation of crude oil, the focus of the domestic pure benzene Market weakened. In addition, in the same period, the domestic logistics in many places was greatly affected, and the regional price difference of domestic pure benzene was also obvious. The mainstream quotation range was 8300-8650 yuan / ton. In the first week after the festival, the bidding price of crude benzene was issued, and 7015-7020 yuan / ton was implemented in Shandong, up 75 yuan / ton from last week’s bidding price. After the middle of the year, the crude oil fluctuated significantly, and the commodity guidance became more and more unclear. Pure benzene was less affected by crude oil, mainly following the demand fluctuation. With the increase of bargain hunting in the downstream, the transaction volume of pure benzene market increased, the price rebounded slightly, and the transaction volume of pure benzene improved compared with the previous period. Local refining prices continued to rise, and the price difference with Sinopec narrowed. The mainstream price of domestic pure benzene was 8400-8550 yuan / ton, and the regional price difference narrowed. In terms of crude benzene, boosted by the industrial chain, the bidding price in Shandong was raised to 7160-7165 yuan / ton, with a slight increase of 240 yuan / ton. At the end of the month, due to the high cost pressure of downstream hydrobenzene enterprises, the arrival price of crude benzene in Shandong is generally high, so there is a strong resistance to high price crude benzene. In addition, the prices of downstream toluene and other commodities are lower, and the enterprise profit is limited. Therefore, the bidding price of crude benzene is reduced slightly at the end of the month, and 6930-6935 yuan / ton is implemented in Shandong, which is reduced again.

 

In terms of start-up: the start-up of coking enterprises in this month is generally low at the beginning of this month, which is mainly affected by the difficulty of upstream coking coal procurement. At the end of the month, the transportation of coking coal in the main production areas resumed, and the overall operating rate rebounded significantly.

 

In the future, the business agency believes that at present, pure benzene is obviously affected by the fluctuation of crude oil trend, and the downstream purchase intention has rebounded to a certain extent. Superimposed on the demand for replenishment before the festival, the price of pure benzene has risen recently, which is supported by good fundamentals. If crude oil continues to rise or support the industrial chain to rise, it still depends on the actual demand and profit of the downstream. It is expected that the crude benzene market will be dominated by strong operation. The follow-up will focus on the price trend of crude oil and external market, and the impact of domestic logistics and transportation on the industrial chain.
