據(jù)石化新聞2020年9月18日休斯敦報(bào)道，今年4月份，當(dāng)疫情大流行導(dǎo)致的停產(chǎn)和經(jīng)濟(jì)沖擊席卷全球大部分地區(qū)時(shí)，建筑材料聚氯乙烯（PVC）的需求降至2008年全球金融危機(jī)以來(lái)的最低水平。

房屋建設(shè)活動(dòng)斷斷續(xù)續(xù)。PVC買(mǎi)家退縮，而PVC賣(mài)家追逐不斷萎縮的需求，但往往徒勞無(wú)功。5個(gè)月以后，這是一幅完全不同的畫(huà)面。美國(guó)和歐洲連續(xù)數(shù)個(gè)月的PVC價(jià)格下調(diào)、需求復(fù)蘇，以及部分不可抗力，已將PVC價(jià)格推至多年高位。在供應(yīng)嚴(yán)重緊張的情況下，買(mǎi)家希望能夠獲得用于制造管道、窗框、乙烯基壁板和其他產(chǎn)品的PVC原料。

一位美國(guó)市場(chǎng)消息人士表示：“目前市場(chǎng)上真的沒(méi)有任何PVC產(chǎn)品?！薄坝猩僭S來(lái)自亞洲。但價(jià)格很高。人們?nèi)缃袷窃诳诖锒皇堑教庂I(mǎi)PVC產(chǎn)品?！?/span>

美國(guó)PVC出口價(jià)格在6周內(nèi)下跌了39%，在4月29日休斯敦PVC廠關(guān)閉的高峰期跌至12年來(lái)的最低點(diǎn)520美元/噸。由于停產(chǎn)緩解，PVC價(jià)格在5月份開(kāi)始反彈，到8月份達(dá)到了800美元/噸的船邊交貨價(jià)格。

隨后，美國(guó)4家PVC生產(chǎn)商中的兩家在8月中下旬宣布PVC受到不可抗力的影響。4月份之后，由于轉(zhuǎn)場(chǎng)或?qū)π枨蟾纳颇芊癯掷m(xù)感到擔(dān)憂，沒(méi)有一家PVC生產(chǎn)商的價(jià)格完全恢復(fù)正常。到9月16日，PVC價(jià)格已經(jīng)從4月29日的低點(diǎn)翻了一番，達(dá)到了1050美元/噸的9年來(lái)高點(diǎn)。

Tight global PVC supply pushes prices to multi-year highs

When coronavirus pandemic-related shutdowns and economic shocks gripped much of the world in April, demand for construction staple polyvinyl chloride careened to lows not seen since the global financial crash in 2008.

Home construction activity cratered. PVC buyers recoiled and sellers chased shrinking pockets of demand, often in vain.

Five months later, it's a starkly different picture. Months of reduced rates, demand recovery and some force majeures on PVC in the US and Europe have pushed prices to multi-year highs. Buyers want the powder that makes pipes, window frames, vinyl siding and other products amid an acute supply squeeze.

"At this moment there's really no product in the market," a US market source said."There's a little coming from Asia. Prices are high. People are buying, in pockets, not everywhere."

US export PVC prices fell 39% in six weeks to a 12-year low of $520/mt FAS Houston on April 29 at the height of the shutdowns. Prices began rebounding in May as shutdowns eased, reaching $800/mt FAS by August.

Then Formosa Plastics USA and Westlake Chemical, two of the four US producers, declared force majeure on PVC in mid and late August. None had resumed fully normal rates post-April amid turnarounds or skittishness about whether improved demand would be sustained. By Sept. 16, prices had doubled from that April 29 low to $1,050/mt FAS, a nine-year high.
