2、 Market analysis

 

With the return of the May Day holiday, the disk is relatively strong, coupled with the increase in the price of raw calcium carbide, the cost support is enhanced, and the PVC futures and spot prices rise hand in hand, but the rise has not lasted for a long time. The rise began to stop in the middle of the year, the mainstream prices across the country began to decline, and the market focus continued to move downward. Although the market has entered the peak season, public health events in various parts of China are still severe, restraining some demand, and the recent market transactions are tepid. As of the 15th, the price of raw calcium carbide is around 4400-4500 yuan / ton, and the quotation range of domestic pvc5 calcium carbide enterprises is mostly around 8600-9000 yuan / ton. At present, CFR China’s price is US $1300 / ton, CFR India’s price is US $1520 / ton, and Southeast Asia’s price is US $1395 / ton.

 

According to the weekly rise and fall from February 21, 2022 to May 15, 2022, it can be seen that domestic PVC rises and falls in the cycle. The maximum increase is in the week of February 28 and the maximum decrease is in the week of February 21. The overall fluctuation is small.

From the perspective of demand: the agricultural demand in Xinjiang and southern China is good, the demand of enterprises in Hefei is increased, the plate factory purchases on demand, and the demand of urea industry is sufficient. Buy up rather than buy down, and the trading atmosphere of urea is good. From the perspective of supply: there were many urea maintenance manufacturers in May, and the supply decreased. Various factors continue to drive up the price of urea. The policy of ensuring supply and price stability remains unchanged.

 

The future price of urea is bearish

 

In the middle of May, the domestic urea market may fluctuate and fall slightly, dominated by consolidation. Urea analysts of business society believe that the upstream market rose slightly and the cost support is better. The agricultural demand is weakened, the demand of compound fertilizer enterprises is general, the plate factory purchases on demand, and the downstream customers have a strong wait-and-see attitude towards high price urea. From the perspective of supply: there are many urea maintenance manufacturers in May, and the urea supply is expected to decline.

Sodium Molybdate

In the futures market, Lun lead fell continuously this week, with a decline of more than 6%, and the operating range was US $2080-2285 / ton, with a wide decline. Affected by the Fed’s interest rate hike, the performance of US data is poor, the overall high operation of the US dollar, the non-ferrous metal market is generally under pressure, most of them are down this week, and Lun lead is under pressure. Shanghai lead’s performance is similar to that of Lun lead. It went down as a whole this week, with an operating range of 14920-15820 yuan / ton, down 5.4% this week and falling continuously during the week. In terms of inventory, Shanghai lead inventory increased significantly this week, rising to 92960 tons by Friday, with a total increase of 10331 tons, which was bad for the market again.

 

In the domestic market, the recent market is in the off-season, and the lead price mainly fluctuates with the futures market, falling 4.37% this week. The high level of the futures market fell, and the spot market generally fell. Basically, due to the impact of refinery maintenance and slightly tight mine end supply, the supply of lead ingots is weak at present. In terms of downstream demand, the battery has entered the traditional off-season market, and the domestic sales situation is general, while the recent performance of foreign orders is also weak, the off-season performance is obvious, and the support for the demand for lead ingots is limited. With the price falling all the way, there are some low-price inquiries in the market, but the overall trading is on the sidelines. On the whole, the metal market is under pressure as a whole, and it is expected that the trend will be weak and volatile in the short term.

The raw material support was obvious, and the market price of liquefied gas rose after the festival

After the May Day holiday, the domestic liquefied gas market rose as a whole, and the civil gas market in Shandong fluctuated and rose, with prices mostly around 6400 yuan / ton. According to the data monitoring of business agency, the average price of liquefied gas in Shandong civil market was 6340.00 yuan / ton on May 1 and 6470.00 yuan / ton on May 7, with an increase of 2.05% and 52.83% compared with the same period last year.

South China., 6390-6600 yuan / ton

Northeast China., 5750-5900 yuan / ton

Shandong Province., 6380-6600 yuan / ton

 

After May Day, the domestic liquefied gas market trend is strong, and most of the prices are dominated by the behavior. During the May Day holiday, the international crude oil rose significantly, which brought obvious support to the market in terms of cost, and the liquefied gas market increased during the holidays. After the festival, there is a certain replenishment demand in the downstream, with good enthusiasm for entering the market and mild market transaction atmosphere. In addition, there is little pressure on the supply of Shandong civil gas market, the manufacturers ship smoothly, have a strong attitude and raise the price. However, there are still negative factors in the current market. With the end of replenishment after the festival, the downstream has withdrawn from the market and consumed inventory. The market transaction atmosphere has weakened compared with that in the early stage. In addition, the weak terminal demand has brought obvious restraint to the market.

 

Chitosan oligosaccharide

After the festival, the LPG futures market rose first and then fell, which brought limited support to the spot market. On May 6, the opening price of LPG futures contract 2206 was 6285, the highest price was 6340, the lowest price was 6120, the closing price was 6182, the former settlement price was 6257, the settlement price was 6226, down 75, the trading volume was 136144, the position was 57610, and the daily position was increased by – 624. (quotation unit: yuan / ton)

 

At present, the international crude oil continues to rise, and the news is good for the market mentality, but the overall trading atmosphere of the market is limited. As the weather continues to warm after the festival, the terminal demand is weak. After the downstream replenishment after the festival, they withdraw from the market one after another to consume inventory, but the supply pressure of Shandong market is not large, which brings some support to the market. It is expected that the market price of Shandong civil gas may weaken in the short term, and the range may be limited.

The price was 8819.8 yuan / ton on April 229 and 8907.4 yuan / ton on May 6, up 0.99% from last week and 18.03% from the same period last year. The rise in crude oil prices, coupled with the increase in on-site demand, led to a rise in the gasoline market.

 

3、 Future forecast

 

In terms of crude oil, the situation in Russia and Ukraine is full of uncertainty, and the fear of tightening oil supply remains unabated. However, high oil prices are bad for the economy and demand, rising inflation or restraining the rise of oil prices, and there is still a risk of violent fluctuations in short-term crude oil. Continue to pay attention to the impact of geopolitical situation, OPEC + decision on crude oil production, US crude oil and refined oil storage dynamics, global economic conditions and other factors on crude oil prices.

 

The trend of crude oil is strong and the cost side is well supported. The favorable gasoline market lacks sustainability, the downstream chemical industry mainly maintains rigid demand, and the logistics and transportation have not been fully recovered, and the demand for toluene is still weak. Overall, toluene support still exists, waiting for demand to recover. Pay attention to the market trend of crude oil and gasoline, and the impact of the dynamics and demand of toluene and downstream devices on the price of toluene.
