Kusukela ngoDisemba 15, umkhuba wenzuzo yezinto zokusetshenziswa ezahlukene ze-polyethylene uwonke ubonise umkhuba wokwenyuka, futhi inzuzo ye-ethylene ezinhlotsheni ezinhlanu zezinqubo yanda kakhulu, kusukela ku-+650 yuan/ton kuya ku-460 yuan/ton ekuqaleni kwenyanga; Kulandelwe inzuzo yamalahle namafutha ekuqaleni kwenyanga +212 yuan/ton kanye ne-+207 yuan/ton kuya ku--77 yuan/ton kanye ne-812 yuan/ton; Ekugcineni, inzuzo ye-methanol kanye nenzuzo ye-ethane, kusukela ku-+120 yuan/ton kanye ne-+112 yuan/ton kuya ku-70 yuan/ton kanye ne-719 yuan/ton ekuqaleni kwenyanga. Phakathi kwazo, inzuzo yokukhiqizwa kwe-methanol kanye ne-ethylene isuka kokubi iye kokuhle. Inzuzo yamalahle kanye nenzuzo ye-ethane ikhuphuke ngo-34.21% kanye no-18.45% kusukela ekuqaleni kwenyanga.

Okokuqala, inzuzo yendlela yenqubo ye-ethylene ikhuphuke kakhulu, ekuqaleni kwenyanga umthwalo webhizinisi lokukhiqiza oyinhloko uyanda, indawo yokusekela amadivayisi angaphansi komfula inamazinga ahlukene okunciphisa umthwalo noma ukupaka, ukuthunyelwa okuphezulu komfula kukhuphukile, abasebenzisi abangaphansi komfula bempahla eluhlaza kuphezulu kakhulu, isidingo sendawo sihamba kancane, okwenza insimu ibe sesimweni sokuntuleka ngokweqile. Ngemva kwesitoko esikhulu sezinto zokusetshenziswa kanye nokwanda kwengcindezi yezindleko kulezi zici ezimbili, inhloso yokuthenga i-ethylene engezansi iyancishiswa, futhi ukugxila kwezingxoxo zemakethe kuphansi. Ngakho-ke, izindleko zendlela yokukhiqiza i-ethylene zalandela ukwehla, kusukela ngomhlaka-15, izindleko zazingama-yuan angu-7660/ton, okwakungama--6.13% kusukela ekuqaleni kwenyanga.

Ngokuphathelene nendlela yenqubo yamalahle, igagasi elibandayo elinamandla kakhulu lisanda kuhlasela izindawo eziningi zezwe lethu kulobu busika, uma kwenzeka ukwehla kweqhwa elinzima ngokuzumayo, imakethe ayiphelelwanga uvalo, intengo yokuqala iyehla ngisho, ukunyuka kwangempela kwempahla kuphela. Igagasi elibandayo alizange likhulise kakhulu ukusebenza kwentengo yendawo yokukhiqiza, intengo iyaqhubeka nesigqi sesilinganiso samalahle ngesonto eledlule, lapho iqhwa lincibilika, intengo izoba sendaweni yokukhiqiza/yokuthutha ngaphambili endaweni yokugcina impahla kanye negagasi elibandayo eningizimu ukuze kuqalwe umdlalo. Izindleko zamalahle inyanga nenyanga -0.77% ku-7308 yuan/ton.

Ngokuphathelene nendlela yenqubo kawoyela, amanani kawoyela akamuva emhlabeni wonke axubile, kanti isizathu esibi ukuthi ukukhathazeka kwemakethe mayelana nombono wesidingo kusekhona. Isizathu esihle sezinto ezigciniwe zikawoyela ongahluziwe wezentengiselwano zase-US sehle kakhulu kunalokho obekulindelwe, kuhlanganiswe ne-Federal Reserve ekhonjiswe ekwehleni kwezinga lenzalo ezintathu ngonyaka ozayo. Njengamanje, amanani kawoyela aphesheya kwezilwandle aphinde asondela eqophelweni eliphansi kakhulu onyakeni, futhi isimo esibuthakathaka asikaqedwa ngokuphelele. Ukuzamazama komhlangano we-OPEC+ kuhlanganiswe nengcindezi evela kumbono wesidingo obuthakathaka kwakuyizinto eziyinhloko. Kodwa-ke, kulo nyaka, u-$70-$72 usephansi kakhulu ku-Brent, futhi kulindeleke ukuthi amanani kawoyela asenendawo yokulungisa phezulu. Izindleko zamanje zokukhiqiza uwoyela zingama-yuan angu-8277/ton, okungu--2.46% kusukela ekuqaleni kwenyanga.
