This week, the domestic propane market continued to rise, the power was insufficient, and the price fell significantly. Most of the Shandong market fell back below 7000 yuan / ton. According to the data monitoring of business agency, the average price of propane in Shandong market was 7163.25 yuan / ton on March 6 and 7438.25 yuan / ton on March 14.

As of March 14, the mainstream prices of propane in different regions in China are as follows:

region . March 14th

East China . 6850-7350 yuan / ton

North China 6800-7200 yuan / ton

Shandong region . 6850-7000 yuan / ton

Northeast China . 6900-7000 yuan / ton

This week, the domestic propane Market as a whole showed a rising and falling trend. The decline of Shandong propane market was greater than the increase, and most of the prices fell back below 7000 yuan / ton. Driven by the rise of international crude oil in the early part of the week, Shandong propane market continued to rise, mainly upward. In the late part of the week, the international crude oil fell significantly, with a bad market mentality, coupled with the obvious resistance of the downstream to high prices, poor enthusiasm for entering the market, weak market trading atmosphere, blocked manufacturers’ shipments and obvious price drop.

Saudi Aramco announced in March 2022 that both propylene and butane increased. Propane was 895 dollars / ton, an increase of 120 dollars / ton over the previous month; Butane 920 US dollars / ton, up 145 US dollars / ton compared with the previous month.

 

On the whole, the current international crude oil continues to fluctuate, which brings limited support to the market. The lower reaches have limited ability to accept high prices, are cautious and wait-and-see, while the southern and northern markets are dominated by weakness. It is expected that the price of propane market may still fall in the short term.

2、 Market analysis

 

Monoammonium phosphate market continued the upward trend this week. As the price of raw materials continued to rise and the cost side continued to exert pressure, the quotation of monoammonium phosphate enterprises increased and the focus of transaction shifted upward. Most enterprises suspended or received a small amount of orders. In the short term, the price of raw materials may continue to rise, and monoammonium will continue to operate at a high level. At present, the mainstream factory quotation of 55 powder ammonium in Henan is about 3300 yuan / ton, the mainstream factory quotation of 55 powder ammonium in Anhui is about 3400 yuan / ton, and the mainstream factory quotation of 55 powder ammonium in Hubei is about 3200 yuan / ton. The actual transaction can be negotiated.

 

The market of diammonium phosphate was adjusted at a high level this week. At present, there is a large amount of diammonium to be sent and there are sufficient orders. With the rise of raw materials and the increase of cost pressure, most enterprises suspend quotation and order receiving, and mainly issue early orders. The fertilizer for spring ploughing is increased, and the downstream is purchased on demand. The order is received carefully. The factory quotation of 64% mainstream diammonium in Hubei is 3600-3650 yuan / ton, that of 64% mainstream diammonium in Yunnan is 3500-3600 yuan / ton, and that of North China is 3750-3850 yuan / ton. The actual transaction is negotiated.

 

The price of raw phosphate rock rose this week. At present, the reference average price in the mainstream areas of 30% grade phosphorus ore in China is around 726 yuan / ton. With the arrival of spring ploughing and sowing season, the downstream of phosphate rock ushers in the peak demand season, the demand performance is good, the on-site trading atmosphere is active, the supply of phosphate rock is more tight, and the intention of mining enterprises to support the price is enhanced. On March 10, domestic mining enterprises in Guizhou and Guangxi raised the market price of medium and high-end phosphorus ore one after another. Among them, the 30% grade phosphorus ore in Guizhou increased by 10-20 yuan / ton, and the low-end price in the field continued to decrease.

The price of raw sulfur continued to rise this week. On March 8, the price of sulfur in East China increased by 15.97% over a single day. At present, the sulfur market is operating at a high level, and individual domestic refineries follow up. The price adjustment range is generally 200-350 yuan / ton. The sulfur market is operating strongly. The reason for the sharp rise is mainly due to the high level of the port market. It is difficult to find the supply of goods in the port. The cargo holders are reluctant to sell, and have a strong intention to rise. The mentality of domestic refineries is positive. Coupled with the steady progress of the downstream phosphate fertilizer market, the price of solid-liquid sulfur runs at a high level.

 

3、 Future forecast

 

The ammonium phosphate analyst of business society believes that at present, due to the rising trend of ammonium phosphate raw materials and the increasing pressure of enterprises, the manufacturers increase the price according to the trend. Downstream procurement is cautious, focusing on just demand. It is expected that in the short term, the price of Monoammonium will continue to rise steadily, and the price of diammonium will be adjusted and operated at a high level, mainly maintaining the ex factory price in the early stage. It is suggested to pay attention to the changes of raw material market.

Us and European sanctions against Russia may escalate, and oil prices soar to the highest level since 2008

On March 7, the price of international crude oil futures rose sharply, reaching a maximum of $139 in Brent crude oil, the highest level since 2008. The settlement price of the main contract of WTI crude oil futures in the United States was US $119.4/barrel, up US $3.72 or 3.2%; The settlement price of the main contract of Brent crude oil futures was US $123.21/barrel, up US $5.1 or 4.3%. The situation in Russia and Ukraine has further deteriorated, and the market is generally pessimistic about its third round of negotiations. The United States and the European Union consider banning the import of crude oil from Russia. At the same time, Iran’s oil is unlikely to return to the international market in the short term, and the supply interruption is expected to continue to push up the oil price.

 

gamma polyglutamic acid fertiliser(fertilizer) grade

As of the 7th, the third round of Russia Ukraine negotiations held in Belarus has ended. According to relevant media reports, the negotiations between the two sides have not achieved the expected results. The situation in Russia and Ukraine is still changing rapidly, and the prospect is full of great uncertainty, which also greatly magnifies the expectation of interruption of crude oil supply.

 

More importantly, the US and EU sanctions against Russia are still escalated. U.S. Secretary of state Blinken said recently that the United States is working with the European Union to study the possibility of prohibiting the import of Russian oil. Prior to this, the United States and its European allies imposed a series of sanctions on Russia. Although they also sacrificed the trump card of “swift” financial sanctions, they did not prohibit oil and gas transactions with Russia. The news further spread the panic caused by the market. The oil market shook on Monday. During the Asian trading session, the price of Brent crude oil futures in London once hit a high of US $139.13/barrel.

 

Gamma Polyglutamic Acid

Judging from the current market reaction, the sanctions have had a real impact on the crude oil supply side. At present, Russia’s energy supply has begun to decline. Under the panic, some buyers dare not sell, the freight rates rise sharply, and it is difficult to find oil ships, which also brings difficulties to buyers. The current situation leads to a large discount on ural crude oil. According to statistics, the daily supply of crude oil in Russia is about 10 million barrels, of which the export volume is about 4-5 million barrels / day, and the daily export of refined oil is nearly 3 million barrels / day. If the sanctions further rise to the energy embargo, it will have a serious impact on the global oil supply.

 

Crude oil analysts of business news agency believe that the current situation in Russia and Ukraine is still a key factor affecting oil prices. Changes in the situation and the escalation of sanctions will exacerbate the volatility of oil prices. Although the current market supply expectation is pessimistic, the oil producing country OPEC + has stated that it will not increase additional production. Although the Iranian nuclear negotiations have made progress, the return of Iranian oil to the international market will not happen overnight, and the supply expectation will form a strong support for oil prices. However, at present, the response of oil prices has gradually deviated from the fundamentals, and the risk premium has risen sharply. At the same time, soaring oil prices bring high costs, which will seriously harm future demand and further lead to the fragility of the industrial chain. The market should beware of the arrival of vicious market.

Gamma Polyglutamic acid food grade

One week after the commencement of the festival, the epoxy resin market negotiation was cold, mainly due to the decline of dual raw materials, the continuous decline of East China auction, the starting price of the on-site auction on the 21st fell to 16000 yuan / ton, and the market continued to fall to 17200 yuan / ton. The upstream and downstream of the short-term industrial chain were mainly bad, but the supply side was tight, and it is expected to operate stably in the short term.

As of February 28, the operation of domestic TDI plants is as follows:

 

The TDI market was strong in February, and the price rose first and then fell in the month. In the first half of the month, the market was still in a state of rapid rise before the festival. The on-site spot supply was tight, and major manufacturers successively raised the guidance price. The holders had a strong attitude of supporting the price, and the distribution market kept up with the rise. Although the market supply is still tight in the second half of the month, the downstream demand is less than expected, and the acceptance of high prices is not high. In addition, the export orders of the terminal industry are weakened, the downstream market entry is dominated by rigid demand, the offer of cargo holders is loose in a narrow range, and the TDI market is weak.

The upstream toluene market fluctuated upward. As of February 28, the price rose to 7363 yuan / ton, an overall increase of 21.62% over the price at the beginning of the month. After the Spring Festival, driven by the rise of the gasoline industry, toluene had a good start. However, the downstream industry resumed work slowly, the market demand was limited, and the price of toluene fell. In late February, the tension between Russia and Ukraine escalated, the short-term rise of crude oil was obvious, and toluene rose again.

 

According to the analysis of TDI data division of business society, the supply of TDI is favorable to the market, but the downstream demand is difficult to promote the continuous rise of prices. From the perspective of supply and demand performance, the short-term TDI market is weak. In terms of digesting the inventory situation in the later stage and the commencement of large factories, the post market situation is mainly stalemate and consolidation, and the specific follow-up situation in the downstream is concerned.
