I te 15 o Tīhema, i piki ake te hua o ngā rauemi mata polyethylene katoa, ā, ko te hua o te ethylene i roto i ngā momo tukanga e rima te mea tino piki ake, mai i te +650 yuan/tana ki te 460 yuan/tana i te tīmatanga o te marama; ā, i whai ake ko ngā hua o te waro me te hinu i te tīmatanga o te marama +212 yuan/tana me te +207 yuan/tana ki te -77 yuan/tana me te 812 yuan/tana; hei whakamutunga, ko te hua o te methanol me te hua o te ethane, mai i te +120 yuan/tana me te +112 yuan/tana ki te 70 yuan/tana me te 719 yuan/tana i te tīmatanga o te marama. I roto i ēnei, ko te hua o te hanga methanol me te ethylene mai i te kino ki te pai. Ko te hua o te waro me te hua o te ethane i piki ake mā te 34.21% me te 18.45% mai i te tīmatanga o te marama.

Tuatahi, kua tino piki ake te hua o te ara tukanga ethylene, i te tīmatanga o te marama kua piki ake te kawenga o te umanga whakaputa matua, he rerekē te whakahekenga kawenga, te tūnga waka rānei o ngā taputapu tautoko i raro, kua piki ake ngā tuku ki runga, he teitei te rarangi rauemi mata o ngā kaiwhakamahi o raro, he puhoi te tono mō te wāhi, ka noho te mara i roto i te āhuatanga o te nui rawa o te tuku. Whai muri i te nui o ngā rauemi mata me te pikinga o te pēhanga utu i runga i ngā āhuatanga e rua, kua heke te hiahia hoko o raro o te ethylene, ā, kua iti ake te arotahi o ngā whiriwhiringa mākete. Nō reira, i whai te utu o te ara whakaputa ethylene i te hekenga, i te 15 o ngā marama, ko te utu he 7660 yuan/tana, arā, -6.13% mai i te tīmatanga o te marama.

Mō te ara tukatuka waro, ko te ngaru makariri kaha rawa atu i pā ki te nuinga o ngā rohe o tō tātou whenua i tēnei hotoke, mēnā ka heke ohorere te hukarere nui, kāore te mākete i pau te taonga, kei te heke te utu taketake, ko te pikinga tūturu ko te uta. Kāore te ngaru makariri i tino whakanui i te mahi utu o te rohe whakaputa, kei te haere tonu te utu i te auau utu iti o te waro i te wiki kua hipa, ina rewa te hukarere, ka noho te utu ki te rohe whakaputa/mua o te mahi kawe ki te whare putunga me te ngaru makariri ki te tonga hei whakarewa i tētahi kēmu. Ko te utu waro ia marama -0.77% ki te 7308 yuan/tana.

Mō te huarahi tukatuka hinu, kua rerekē ngā utu hinu o te ao i ngā wā tata nei, ā, ko te take kino ko te noho tonu o ngā āwangawanga o te mākete mō te tirohanga tono. Ko te take pai mō te hekenga o ngā taonga hinu mata arumoni o te US i nui atu i te mea i whakaarohia, me te tohu a te Federal Reserve mō ngā whakahekenga reiti huamoni e toru i te tau e tū mai nei. I tēnei wā, kua tata anō ngā utu hinu o te ao ki te wāhi iti rawa o te tau, ā, kāore anō kia tino whakakorea te āhuarangi ngoikore. Ko ngā ru i muri mai i te hui a te OPEC+ me te pēhanga mai i te tirohanga tono ngoikore ngā take matua. Heoi, i tēnei tau, ko te $70-$72 he raro pumau tonu mō Brent, ā, e matapaetia ana kei te wātea tonu ngā utu hinu ki te whakatika ake. Ko te utu whakaputa hinu o nāianei ko te 8277 yuan/tana, arā, -2.46% mai i te tīmatanga o te marama.
