Kuva 2023, igiciro cyisoko cya Styrene cyakoraga munsi yimyaka 10. Kuva irashobora, iragenda itandukana kuva mumyaka 10. Impamvu nyamukuru nuko igitutu cya bengene cyera zitanga imbaraga zo kuzamura amafaranga kugirango wagure ikiguzi cya Styrene. Muri rusange, igiciro cya Styrene gishobora gukomeza kwishingikiriza ku buyobozi bwa motu, kandi bikabuza gutanga no gukenera ku kwanduza ibiciro birashobora kugorana.
Kuva 2023, ibiciro bya Stryone byakomeje gukora munsi yumwaka wimyaka 10 igenda. Ku ruhande rumwe, gusohora byihuse umusaruro mushya wa Styrene byatumye habaho intege nke zicika intege no gusaba umubano; Ku rundi ruhande, kuva amaraso ya Zhongyuan yinjiye mu muyoboro wo hepfo mu 2022, byarahanze amaso kandi bihindagurika, nta nzira yo hejuru. Muri iki gihe, hejuru ya benzene yeruye abishingikirije ku isoko ryiza kandi basaba umubano wo gushyigikira igiciro cya Styrene. Ariko, muri Gicurasi, nkuko gutanga no gusaba umubano wa Bengine Byera buhoro buhoro bagabanaga, ibiciro bya Stryone

nanone bahanganye n'igitutu cyo kumanuka.
 
Igiciro: Biragoye kumavuta yubukorikori kugirango yerekane icyerekezo kimwe, ariko gutanga na bezene nibyiza byanze bikunze gucika intege cyangwa gukomeza imbaraga.
Nkibicuruzwa byingufu, amavuta yubukorikori azakomeza guhindagurika ku isoko mumezi atatu yakurikiyeho kubera inyungu ya macro yitezeko na micro. Nta makimbirane akomeye, kandi igiciro cya peteroli kizakomeza guhindagurika murwego. Amerika yamavuta yibanze kumadorari 65- $ 85 kuri barriel. Kugeza ubu, hari ibintu bitatu byingenzi byiganjemo ibiciro bya peteroli, aribyo bigorwaho byimazeyo amafaranga, OPEC + Guhindura Umusaruro, hamwe na marginal impinduka mubukungu bwa Macro n'Ubukungu. Birakenewe ko witondera ingaruka zitunguranye kubiciro bya peteroli muriyi ngingo itatu yingenzi.
Kuva muri Werurwe, benye benzene bashingiye cyane ku gutanga no gusaba (hamwe no kuvuza amavuta yo kuvanga kw'amavuta mu Burayi no muri Amerika, n'ibikoresho byinshi muri Aziya, bitwara ikiguzi cya benzene yo hanze; kubyara gihamye, ariko hamwe no gusohora umusaruro mushya wa Downstros, icyifuzo cyayongereye). Mugihe cyo kongera ibiciro bya peteroli no kwanduza amavuta, habaye urusaku rwinshi rwa Styrene, mugihe mugihe cyigiciro cya peteroli gigabanuka no kwanduza imyanda, habaye inkunga isobanutse kubiciro bya Styrene. Kuva ku biciro bitandukanye hagati ya Benzine Yera na Stryrene mu gishushanyo cya 3, birashobora kugaragara ko kuva hagati ya Mata kugeza mu mpera z'ikiruhuko no gusaba, kandi itandukaniro ry'ibiciro ryakomeje kugabanya, rikangura muri 1080 Yuan / ton mu mpera za Mata.
Ariko, muri Gicurasi, ingaruka za benzene yera kuri Styrene zacitse intege cyane, cyane cyane kubera ubwiyongere bwa buhoro buhoro mu mibare yo kubungabunga benerat nziza, kandi hiyongereyeho ubucuruzi bw'imbere mu burasirazuba bwa Tank ya Ubushinwa Umurima, biteganijwe ko ugomba kubarura. Hagati aho, icyifuzo cyo kuvanga peteroli mu Burayi no muri Amerika ntikiyongereye, bifasha kurekura. Ariko, hamwe no kugaruka gukomeye mubihingwa bya Aziya byera benzene, bitangwa byongereye umwe umwe, kandi ibiciro byo hanze biri munsi yumuvuduko runaka.
Gutanga no gusaba umubano: ingorane zo kwanduza imbaraga no kubangamira imbaraga
Mugihe hari impinduka kubiciro no kubisabwa, ingaruka zigiciro ku giciro cya Styrene cyahinduye gusohora igitutu, ariko umubano usaba urashobora kugorana guhinduka cyane.
Icyambere, mubijyanye no gutanga, guhera hagati ya Gicurasi, umubare wibikoresho byo kubungabunga styrene byiyongereye, hamwe namasosiyete 8 yose atangira gusana toni zigera kuri miliyoni 3.2 z'ubushobozi bwa miliyoni 3.2. Muri Kamena, biteganijwe ko umusaruro wa Styrene ugabanuka kuri toni 110000 kugeza kuri toni miliyoni 1.24 ugereranije na Gicurasi, kugabanuka kwa 8.15% ugereranije n'ukwezi gushize.

Icya kabiri, mubijyanye nibisabwa, umusaruro wa Styrentream muri kamena uri mubihe bihenda, kandi icyifuzo cya Styrene gishobora kugabanuka. Dukurikije amakuru ava kuri 2021 kugeza 2022, icyifuzo cya Styrene mu turere ndwi ya Styreke rwagabanutse, bigabanuka kwa 11% muri 2022. Ariko, ni hafi yimpinduka mubikorwa muri 2022, kandi hariho imihindagurikire hagati gutanga no gutanga impande.

Muri rusange, gutanga no gusaba Styrene byagabanutse muri Kamena, ariko hamwe no guhindura imibare yo gutanga no kugirirwa nabi, birashobora kugorana gutanga kandi bikagorana kugana ikiguzi cya Styrene . Igiciro cya Styrene gishobora gukomeza kwishingikiriza kumurongo wigiciro cyo guhindura umurongo ngenderwaho.
