Kwisi yose PVC isabwa nibiciro byombi biragabanuka.

Kuva mu 2021, isi yose ikenera polyvinyl chloride (PVC) byagaragaye ko izamuka rikabije ritagaragara kuva ikibazo cy’imari ku isi cyabaye mu 2008. Ariko hagati ya 2022, PVC isaba gukonja vuba kandi ibiciro biragabanuka kubera kuzamuka kwinyungu hamwe n’ifaranga ryinshi mu myaka mirongo.

Muri 2020, icyifuzo cya PVC gikoreshwa mu gukora imiyoboro, inzugi n’idirishya, imyirondoro ya vinyl n’ibindi bicuruzwa, byagabanutse cyane mu mezi ya mbere y’icyorezo cya COVID-19 ku isi mu gihe ibikorwa by’ubwubatsi byatinze. Amakuru ya S&P Global Commodity Insights yerekana ko mu byumweru bitandatu kugeza mu mpera za Mata 2020, igiciro cya PVC cyoherejwe muri Amerika cyagabanutseho 39%, mu gihe igiciro cya PVC muri Aziya na Turukiya nacyo cyagabanutseho 25% kigera kuri 31%. Ibiciro bya PVC n’ibisabwa byazamutse vuba hagati mu mwaka wa 2020, hamwe n’iterambere rikomeye kugeza mu ntangiriro za 2022. Abitabiriye isoko bavuze ko uhereye ku cyifuzo, ibiro byo mu rugo bya kure ndetse n’abana biga mu ngo ku rubuga rwa interineti byateje imbere iterambere ry’imiturire ya PVC. Ku ruhande rw’ibicuruzwa, ibiciro byinshi byo gutwara ibicuruzwa byoherezwa muri Aziya byatumye PVC yo muri Aziya idahiganwa kuko yinjira mu tundi turere hafi ya 2021, Amerika yagabanije itangwa kubera ibihe by’ikirere gikabije, ibice byinshi by’ibicuruzwa mu Burayi byarahungabanye, n’ibiciro by’ingufu bakomeje. Kuzamuka, bityo kuzamura cyane ibiciro byumusaruro, bigatuma ibiciro bya PVC kwisi bizamuka byihuse.

Abitabiriye isoko bahanuye ko ibiciro bya PVC bizasubira mu ntangiriro za 2022, hamwe n’ibiciro bya PVC ku isi byagabanutse buhoro. Icyakora, ibintu nko kwiyongera kw’amakimbirane y’Uburusiya na Ukraine ndetse n’icyorezo muri Aziya byagize ingaruka zikomeye ku cyifuzo cya PVC, kandi ifaranga ry’isi yose ryatumye ibiciro by’ibiciro by’ibikenerwa nk’ibiribwa n’ingufu, ndetse n’izamuka ry’inyungu ku isi n'ubwoba bw'ihungabana ry'ubukungu. Nyuma yigihe cyizamuka ryibiciro, isoko rya PVC ryatangiye guhagarikwa.

Ku isoko ry’amazu, nk’uko imibare yatanzwe na Freddie Mac ibigaragaza, impuzandengo y’inguzanyo y’imyaka 30 y’Amerika muri Amerika yageze kuri 6.29% muri Nzeri, aho yavuye kuri 2.88% muri Nzeri 2021 na 3.22% muri Mutarama 2022. Igipimo cy’inguzanyo cyikubye inshuro zirenga ebyiri ubu, cyikuba kabiri kwishura buri kwezi no kugabanya inguzanyo z’abaguze amazu, Stuart Miller, umuyobozi mukuru wa Lennar, uwa kabiri mu banyamerika bubaka amazu muri Amerika, muri Nzeri. Ubushobozi bwo "kugira ingaruka zikomeye" ku isoko ryimitungo yo muri Amerika ntibuza kugabanya icyifuzo cya PVC mubwubatsi icyarimwe.

Ukurikije igiciro, amasoko ya PVC muri Aziya, Amerika n'Uburayi aratandukanye cyane. Mugihe ibiciro byubwikorezi byagabanutse kandi PVC yo muri Aziya yagaruye irushanwa ryisi yose, abakora ibicuruzwa muri Aziya batangiye kugabanya ibiciro kugirango bahatane kugabana isoko. Abakora ibicuruzwa muri Amerika nabo bitabiriye igabanuka ryibiciro, bituma ibiciro bya PVC muri Amerika na Aziya bigabanuka mbere. Mu Burayi, igiciro cy’ibicuruzwa bya PVC mu Burayi kiri hejuru kurusha mbere kubera ko hakomeje kubaho ingufu nyinshi ndetse n’ibura ry’ingufu, cyane cyane kubera ko amashanyarazi ashobora kuba make, bigatuma igabanuka rya PVC riva mu nganda za chlor-alkali. Ariko, kugabanuka kwibiciro bya PVC muri Amerika birashobora gufungura idirishya ryubukemurampaka muburayi, kandi ibiciro bya PVC byi Burayi ntibizava mu ntoki. Byongeye kandi, icyifuzo cya PVC cy’iburayi nacyo cyaragabanutse kubera ubukungu bwifashe nabi ndetse n’ibikoresho byinshi.
