Ukusukela nge-15 kaDisemba, indlela yenzuzo yezixhobo ezahlukeneyo zepolyethylene iyonke ibonise ukunyuka, kwaye inzuzo ye-ethylene kwiintlobo ezintlanu zenkqubo yonyuke kakhulu, ukusuka +650 yuan/toni ukuya kwi-460 yuan/toni ekuqaleni. yenyanga; Ilandelwa ngamalahle kunye nenzuzo yeoli ekuqaleni kwenyanga +212 yuan/ton kunye +207 yuan/ton ukuya -77 yuan/ton kunye 812 yuan/ton; Ekugqibeleni, inzuzo ye-methanol kunye nenzuzo ye-ethane, ukusuka +120 yuan/ton kunye +112 yuan/ton ukuya kwi-70 yuan/ton kunye ne-719 yuan/ton ekuqaleni kwenyanga. Phakathi kwabo, imveliso ye-methanol kunye ne-ethylene yenza inzuzo ukusuka kwi-negative ukuya kwi-positive. Ingeniso yamalahle kunye ne-ethane inyuke nge-34.21% kunye ne-18.45% ukususela ekuqaleni kwenyanga.

Okokuqala, inkqubo ye-ethylene indlela inzuzo inyuke kakhulu, ekuqaleni kwenyanga ukunyuka komthwalo wemveliso yeshishini, i-superposition exhasa izixhobo ezisezantsi zinemigangatho eyahlukeneyo yokunciphisa umthwalo okanye yokupaka, ukuthunyelwa kwempahla enyukayo kwanda, abasebenzisi abasezantsi boluhlu lwezinto ezibonakalayo phezulu ngokwentelekiso, imfuno ngebala ivila, ukwenza intsimi kwimeko yonikezelo ngokugqithisileyo. Emva kokuba isitokhwe esiphezulu sezinto eziluhlaza kunye nokunyuka koxinzelelo lweendleko kwimiba emibini, injongo yokuthenga ezantsi kwe-ethylene icinezelekile, kwaye ingqwalasela yeengxoxo zemarike iphantsi. Ngoko ke, iindleko zendlela yokuvelisa i-ethylene ilandele ukuhla, ukususela ngo-15, ixabiso laliyi-7660 yuan / ton, eyayiyi-6.13% ukususela ekuqaleni kwenyanga.

Ngokubhekiselele kwindlela yenkqubo yamalahle, eyona ngqele ibanda kakhulu isandula ukutshayela iindawo ezininzi zelizwe lethu kobu busika, kwimeko yokwehla ngequbuliso kwikhephu elinzima, imarike ayiphumi kuphakuzeleko lwesitokhwe, ixabiso lemvelaphi liyehla, eyona nto iyiyo. nyuka imithwalo kuphela. Igagasi elibandayo alizange likhulise kakhulu ukusebenza kwexabiso lendawo yemveliso, ixabiso liqhubela phambili isingqisho esithe tyaba sesicaphulo samalahle kwiveki ephelileyo, xa ikhephu linyibilika, ixabiso liya kuba kwindawo yokuvelisa/impahla phambi kwendawo yokugcina impahla kunye nokubanda. ulingise emazantsi ukuze uqalise umdlalo. Iindleko zamalahle ngenyanga-ngenyanga -0.77% kwi-7308 yuan / ton.

Ngokwendlela yenkqubo ye-oyile, amaxabiso e-oyile akutsha nje axutyiwe, kwaye isizathu esibi sesokuba iinkxalabo zemarike malunga nenkangeleko yemfuno zisekhona. Isizathu esincumisayo soluhlu lwempahla ye-oyile ekrwada yorhwebo lwase-US lwehle kakhulu kunoko bekulindelekile, kudityaniswe ne-Federal Reserve ethe yabonisa ukuthotywa kweqondo lenzala kathathu kulo nyaka uzayo. Okwangoku, amaxabiso e-oyile kumazwe ngamazwe aphinde afikelela kwelona nqanaba lisezantsi enyakeni, kwaye umoya obuthathaka awukapheli ngokupheleleyo. Iinyikima emva kwentlanganiso ye-OPEC+ kudityaniswe noxinzelelo oluvela kwimbonakalo yemfuno ebuthathaka ibe zezona zinto ziphambili. Nangona kunjalo, kulo nyaka, i-$ 70- $ 72 isengaphantsi eqinile kwi-Brent, kwaye kulindeleke ukuba amaxabiso eoyile asenayo indawo yokulungisa phezulu. Ixabiso langoku lokuvelisa ioli yi-8277 yuan / ton, eyi-2.46% ukususela ekuqaleni kwenyanga.
