Ukususela nge-15 kaDisemba, inkqubela yenzuzo yezinto ezahlukeneyo eziluhlaza ze-polyethylene iyonke ibonise inkqubela phambili, kwaye inzuzo ye-ethylene kwiintlobo ezintlanu zeenkqubo inyuke kakhulu, ukusuka kwi-+650 yuan/ton ukuya kwi-460 yuan/ton ekuqaleni kwenyanga; Kulandelwe yinzuzo yamalahle neoyile ekuqaleni kwenyanga +212 yuan/ton kunye ne-+207 yuan/ton ukuya kwi--77 yuan/ton kunye ne-812 yuan/ton; Ekugqibeleni, inzuzo ye-methanol kunye nenzuzo ye-ethane, ukusuka kwi-+120 yuan/ton kunye ne-+112 yuan/ton ukuya kwi-70 yuan/ton kunye ne-719 yuan/ton ekuqaleni kwenyanga. Phakathi kwazo, imveliso ye-methanol kunye ne-ethylene inenzuzo ukusuka kwi-negative ukuya kwi-positive. Inzuzo yamalahle kunye nenzuzo ye-ethane inyuke nge-34.21% kunye ne-18.45% ukususela ekuqaleni kwenyanga.

Okokuqala, inzuzo yendlela ye-ethylene inyuke kakhulu, ekuqaleni kwenyanga umthwalo oyintloko wemveliso uyanda, indawo exhasa izixhobo ezisezantsi zinezinga ezahlukeneyo zokunciphisa umthwalo okanye ukupaka, ukuthunyelwa okuphezulu kuyanda, abasebenzisi abasezantsi bezinto eziluhlaza baphezulu, imfuno yebala licothayo, okwenza intsimi ibe kwimeko yokubonelela ngokugqithisileyo. Emva kwesitokhwe esiphezulu sezinto eziluhlaza kunye nokunyuka koxinzelelo lweendleko kwiinkalo ezimbini, injongo yokuthenga i-ethylene esezantsi iyancitshiswa, kwaye ingqwalasela yengxoxo yemarike iphantsi. Ke ngoko, iindleko zendlela yemveliso ye-ethylene zilandele ukwehla, ukusukela nge-15, ixabiso yayiyi-7660 yuan/ton, eyayiyi-6.13% ukususela ekuqaleni kwenyanga.

Ngokuphathelele indlela yenkqubo yamalahle, igagasi elibandayo elinamandla kutshanje litshayele uninzi lweendawo zelizwe lethu ebusika, kwimeko yokwehla ngequbuliso kwekhephu elinzima, imakethi ayiphelelwanga luloyiko, ixabiso lemvelaphi liyehla, ukunyuka kokwenyani kwempahla kuphela. Igagasi elibandayo alizange linyuse kakhulu ukusebenza kwexabiso lendawo yemveliso, ixabiso liyaqhubeka nesingqisho esithe tyaba sekowuteshini yamalahle kwiveki ephelileyo, xa ikhephu linyibilika, ixabiso liya kuba kwindawo yemveliso/yolungiselelo ngaphambili kwindawo yokugcina impahla kunye negagasi elibandayo emazantsi ukuqalisa umdlalo. Ixabiso lamalahle inyanga nenyanga -0.77% kwi-7308 yuan/ton.

Ngokuphathelele indlela yenkqubo yeoyile, amaxabiso eoyile aphesheya kwezilwandle asandul’ ukudibana, kwaye isizathu esibi kukuba inkxalabo yemarike malunga nombono wemfuno isasekho. Isizathu esihle sokuba ii-oyile eziluhlaza zorhwebo zase-US zehle kakhulu kunokuba bekulindelwe, kunye ne-Federal Reserve ebonise ukuncitshiswa kwenzala kathathu kunyaka ozayo. Okwangoku, amaxabiso eoyile aphesheya kwezilwandle aphinde asondela kwinqanaba eliphantsi kunyaka, kwaye umoya obuthathaka awukapheliswa ngokupheleleyo. Uxinzelelo oluvela kwintlanganiso ye-OPEC+ kunye noxinzelelo oluvela kumbono wemfuno obuthathaka zezona zinto ziphambili. Nangona kunjalo, kulo nyaka, i-$70- $72 isesezantsi kakhulu kwiBrent, kwaye kulindeleke ukuba amaxabiso eoyile asenendawo yokulungisa phezulu. Ixabiso langoku lemveliso yeoyile yi-8277 yuan/ton, eyi--2.46% ukususela ekuqaleni kwenyanga.
