Oversupply, weak demand to squeeze ethylene, EG during second half

Banner Image

The seasonal rebound in global ethylene derivative demand forecast for the second quarter failed to materialize, and market participants now expect sluggish demand and oversupply to persist through the end of 2023.

China, in particular, has disappointed expectations. Producers had hoped a recovery in Chinese domestic demand would absorb local supply, reducing exports and tightening the international market, but that has not occurred. Worse, new ethylene capacities continue to come online.

"So far the recovery is much slower than what we expected," a Northeast Asia trader told S&P Global Commodity Insights. "It seems like there are not many bullish factors even in the second half of this year."

The 45 million metric tons per year of ethylene capacity slated for startup during 2020-2024 – 25 million tons in China alone – are expected to exceed demand by more than 9%, according to Paul Joo, director/olefin and olefin derivatives, APAC at Commodity Insights.

Europe remains challenged by volatile upstream energy and utility costs, and despite the fall in headline inflation, the Russia-Ukraine conflict is expected to remain a drag on the economy. Conditions in the ethylene did not improve as anticipated during the first half of 2023, and market participants now expect continued weak demand and oversupply during the second half.

European prices for derivative ethylene glycol (EG) have lingered at historic lows and, in most cases, at levels below cash cost. Demand for downstream polymer polyethylene terephthalate (PET) has also been historically weak, with consumers economizing in the face of rising food prices and interest rates.

"I'm not optimistic," a European trader said. "The low volumes, the naphtha price and these imports flowing in, and producers [are still] in expensive mode."

US adding ethylene export capacity

European suppliers also expect more import pressure from cost-advantaged ethane-based producers in the US.

Reduced derivative rates in the US have freed ethylene for export, such that Enterprise Products Partners' 1 million metric ton per year ethylene export terminal in Texas operated at 120% to 125% of capacity through much of 2022. The company is expanding the terminal's capacity by 50% in 2H 2023, and will add another 50% by 2026.

The ethane advantage is also expected to support strong downstream EG production despite weak demand for PET bottling.

China, the largest global consumer of EG, has dramatically increased its domestic production capacity, but poor margins in Asia have discouraged production, while imports from the US have increased, sources said. EG exports to Europe are expected to continue at subdued levels amid antidumping duties ranging from 3% to 60%, depending on the company.

Oversupply is expected to linger, barring a significant disruption such as a hurricane striking the US Gulf Coast, where EG production is centered. Even then, because EG production outstripped demand during the second quarter, stocks should be sufficient to offset outages, sources told Commodity Insights.

Asian EG suppliers said reduced production rates in the regions will continue until margins strengthen, and they expect output to remain low for the next few years. Downstream textile and bottle-grade PET demand has lagged EG supply, a source said.

EG plants could transition from economic run cuts to permanent capacity shutdowns of older, inefficient plants where possible, sources noted. Capacity additions slated for 2023 would offset such rationalizations, but startups could be delayed given a shaky economic outlook, traders said.

INTERVIEW: Alphamar director sees 17 million mt of Brazilian corn going for ethanol

Ethanol will create new prospects for Brazilian corn in the domestic market, with corn for ethanol use rising sharply to 17 million mt in the next marketing year, Arthur Neto, partner director at Alphamar Shipping Agency, told S&P Global Commodity Insights June 12. Register Now Pointing to the impact on domestic and export markets, Neto said on the sidelines of the IGC Grains Conference in London that increased use of ethanol for corn will push prices up, incentivizing corn production in a situation where "the market is flooded by corn because you don't have much exit for it in the domestic market." "This is going to be a dynamic that's going to make the price on the domestic market go higher, which makes the producers maintain the corn inside, meaning that if you have export demand, you need to pay much more," Neto said of the expectation of 17 million mt of corn for ethanol usage in marketing year 2024-25. For 2023, the figure was 13.26 million mt. Speaking on whether Brazilian corn is trading higher than competitors' in the current season, Neto said, "you have to understand that the market is very heated internally, so it doesn't make sense for the farmer to just sell it at pennies for the international market." "I do believe that there's going to be a lot of market, but not as much as in the previous year, because the market is good for the farmer domestically, and they will hold on to the cargo in the country, even though there are many incentives to export," Neto added. 'We are here to sell' Responding to speculation around China's move to bridge the gap between its domestic supply and consumption and what it means for its biggest supplier, Brazil, Neto said carrying out that plan would take time. "China is growing, not as much as it was, but there's a lot coming out of there," Neto said. Any change in China's domestic supply and demand equation will have a major impact on the global balance sheet, considering China's position as the biggest demand center for corn. "I wish them the best of luck," Neto said. "I hope they make it and reach their goals. Meanwhile, we are here to sell." Big flooding impact on soybeans, less on rice Speaking about flooding in Rio Grande do Sul, a key agricultural province that was expected to produce 70% of the country's rice and about 15% of its soybeans in the current marketing year, Neto said the floods were less likely to have a major impact on rice, but soybean production could take a hit. "Roughly 85% of the rice was already harvested when we had the floods," Neto said. "Now we just have logistics issues. Some delays are expected, but not much." However, he said he thought the floods would leave their mark on soybean production, a big factor considering Rio Grande do Sul's strategic location closer to major ports. "Soybeans were the core produce in the region, shipped to the port close to it," Neto said. "That system itself is going to lose a lot of volume." Neto further pointed to the floods in Rio Grande do Sul causing a terminal outage, which is posing a "big risk to the entire export ecosystem." Lower water levels a concern for shipping Brazil's northern ports saw some of the lowest water levels on record last year because of a severe Amazon drought, forcing cargoes to be diverted to Santos. The Alphamar director compared challenges in the northern ports to those on the Mississippi River in the US in the previous year. "When we talk about the northern ports, we're not talking about any problems with the capability on the ports," Neto said. "The water levels are OK. The problem is the cargo being transferred." He added that at some point, the water level will be so low that convoys will have to be disassembled to pass over shallow areas. "Sometimes a trip that is to be done in two days can take around five, so of course, with the total turnaround of the barges, it's very bad," Neto said, adding that there could be two months of major shipping challenges.

Challenging H2 outlook for olefins: The supply/demand imbalance is likely to intensify unless start-ups are delayed

Despite continued year-over-year improvement in demand, conditions in the global olefin markets will remain challenging during the second half, according to market players and analysts. Capacity rationalizations in Europe are expected to have little impact on the regional scene, while the global supply/demand imbalance will continue to intensify, particularly in China. Ethylene demand in Europe is expected to remain weak during the second half and supply to remain long. Rationalization will begin, with ExxonMobil removing 425,000 metric tons of ethylene capacity by shutting down its steam cracker in Gravenchon, France and Sabic removing another 530,000 metric tons of capacity by shutting down its steam cracker in Geleen, the Netherlands. However, market sources do not expect to see much impact from the two closures. “The effects on the market will be minor,” a producer told Commodity Insights. “The whole market will continue as it has in the first half of the year, although the reasons may change.” More rationalization could be in the works. During the second quarter, LyondellBasell Industries announced a strategic review of its European assets, citing expectations of long-term challenging market conditions and increasing cost pressures from European regulations. Ethylene producers in Europe have low expectations of a demand recovery in the second half, with plans to keep cracker run rates at reduced levels despite the upcoming rationalization. Derivative appetite is also expected to remain low, with consumers maintaining reduced contractual volumes. “The rationalization in Europe is a good start,” said Andy Orszynski, director/olefins and derivatives at S&P Global Commodity Insights, “but it is barely scratching the surface in solving the global oversupply picture.” The Asian ethylene markets are expected to remain under pressure, with naphtha-fed steam crackers in particular struggling to balance feedstock costs and derivative margins. Given the weak macroeconomic outlook, buying appetite is set to remain lackluster, leaving supply long, even with most crackers maintaining reduced run rates. “Overall consumption of finished goods is likely to remain capped, as the post-coronavirus recovery has yet to really take off,” said a trader based in Northeast Asia. “Inflation remains high, and economic growth is slow, which will continue to impact consumer spending as well as major infrastructure projects that tend to drive downstream demand and market sentiment. This will all eat into ethylene demand.” With production margins for key derivatives such as polyethylene, ethylene glycol, styrene and polyvinyl chloride in negative territory, the ethylene complex is expected to remain soft. Commodity Insights expects producers in the region to delay most new steam cracker start-ups into 2025 and beyond, so that only two new crackers will begin operations during the second half of 2024. Ethylene supply has been long in the US as well, so pricing there was stable during the first half despite production issues. Unless there is significant change in downstream demand, prices are expected to remain stable in the second half, market sources said. No changes in cracker capacity have been announced for the remainder of the year, but it remains to be seen whether hurricane season, which extends from June through November in the US Gulf Coast, will affect run rates. As for demand, Enterprise Products Partners expects to bring online the 50% expansion of its 1 million metric tons (MMt) per year ethylene export terminal on the Houston Ship Channel. The company has also announced plans for a second 50% expansion during the latter half of 2025. The impact of increased export levels remains to be seen; it is unclear how they will affect trade flows given capacity shifts in Europe and Asia, according to Walt Hart, executive director/olefins, Americas at Commodity Insights. Propylene supply surging on PDH start-ups Conditions in Europe’s propylene market were volatile during the first half of 2024. Looking ahead, the volatility is expected to diminish as trade flows that were diverted by security challenges in the Red Sea normalize. But while market players expect year-over-year gains in demand to continue, underlying oversupply and weakness in key derivatives will limit any broad improvement in market conditions. Europe continues to command significant premiums to Asia and the Americas, raising concerns that the continent will be exposed to competitive import availability if security in the Red Sea improves. Supply of downstream polypropylene (PP) is expected to remain tight due to reduced imports and outage-driven restrictions on domestic availability, but weakness in underlying demand from the key construction and automotive sectors is likely to mitigate any recovery in buyer appetite. “Any easing of [propylene] conditions will impact the PP industry in provoking bearishness, exacerbating oversupply,” one PP producer told Commodity Insights. “We were more optimistic for Q2 than we are now for the rest of the year.” As in the ethylene market, capacity rationalization remains a dominant factor in the outlook for Europe, and speculation on further shutdowns will continue to weigh on industry confidence. In Asia, new propane dehydrogenation (PDH) capacity will further lengthen an already oversupplied propylene market, exacerbating price pressure amid tepid demand. S&P Global Commodity Insights expects four Chinese PDH plants totaling 2.61 million metric tons to start up in the second half, joining the five units totaling 3.6 MMt that went online during the first half. China, a key demand outlet in Asia, may lower its appetite for imported material, and with propylene derivative margins already squeezed by subdued end demand, the result is likely to be minimal spot buying. China’s PDH expansions will also strongly influence trade flows in PP as the country shifts to a net export position. Four new plants totaling 1.25 MMt per year of PP capacity are slated to start up in China during the second half, including Sinopec and Ineos’ 350,000 metric tons per year Tianjin line and ExxonMobil’s two 450,000 metric tons per year Huizhou lines. Traders have been noting aggressive offers for China-origin PP homopolymer cargo in Southeast Asia. “The China-SEA freight situation is not nearly as bad as costs to ship to the Americas and Europe, which makes trades more workable,” a Northeast Asian trader said. In the Americas, feedstock propane prices are expected to stabilize during the second half, which could help stabilize propylene spot pricing, Hart said. The market has expressed a similar sentiment, with one source anticipating stable-to-bearish pricing as long as production is kept balanced. Another source said that increased diversification of demand is likely, with various derivative units coming back online and expanding the downstream consumption base beyond traders. Downstream, PP market participants expect challenging fundamentals as new capacity comes online during a period of lackluster export demand. Formosa Plastics Corp. will bring its new 250,000 metric tons per year PP plant online at Point Comfort, Texas in July, according to a source familiar with company operations. At the same time, the existing PP unit at the facility will be taken offline for maintenance to be completed in the third quarter. Elevated propylene pricing has been making it difficult for US exporters to compete with Asian-origin PP material. Run rates have been reduced below 80%, and they are expected to remain there during the second half as producers focus on domestic sales. This article first appeared in Chemical Week .

CHEMICALS OUTLOOK: Asian paraxylene braces for softer H2 as surging stocks restrain China demand

After the challenging first five months of 2024, participants in the Asian paraxylene market are gearing for more pain in the second half, as top consumer China battles growing domestic inventories along with higher production, while global demand recovery remains nascent. Asian PX prices averaged at $1,031.72/mt so far this year, recovering from a year-to-date low of $1,001/mt reached on May 14, according to Platts assessments by S&P Global Commodity Insights. However, prices remained below the January-May 2023 average of $1,045.29/mt. Market participants in Asia were hopeful of a strong first-half on gasoline blending demand ahead of the US summer driving season. However, the optimism was tempered by surging aromatics inventories and ample availability of spot cargoes. Although US gasoline buyers have been purchasing blendstocks since early 2024, plentiful supplies capped buying appetite. And the latest energy outlook by the EIA further dampened hopes of any meaningful demand rival in H2. US gasoline consumption is seen at 8.91 million b/d in 2024, down 0.34% on the year, according to EIA's short-term energy outlook forecasts. The estimate for Q3 consumption is at 9.14 million b/d, or 0.99% higher than in 2023, but 8.81 million b/d for Q4, down 1.34% from last year. Given the current scenario, there is little hope that PX prices will hit new highs in the latter half of the year, a trader in Singapore said. "I don't see any upside at the moment unless something changes due to production issues [in Asia], then maybe it helps the situation," the trader in Singapore said. Producers have opted for turnarounds in April and May, which has helped prevent a supply glut, the trader added. "I feel there's more pain to come [for PX prices], so we don't know if there's a next leg down," a second trader in Singapore said. Margin squeeze PX margins have trended lower so far this year, with the spread between CFR Taiwan/China PX and C+F Japan naphtha staying below the $350/mt mark, Commodity Insights data showed. PX supplies in Q3 are likely to increase with refinery turnaround season ending in Q2. Furthermore, there are still some hopes for gasoline blending demand though it may not be as strong as 2022 and 2023, said Xiaodong Zhang, director of aromatics analytics at Commodity Insights. According to Xiaodong, one major Chinese producer may undergo PX plant turnaround in Q3, which could impact supplies, though plans remained unconfirmed. Downstream worries Moreover, expectations of additional PTA capacities coming online in China also weighed on market sentiment, said producers. "We are thinking [that the] PX, PTA and polyester chain does not look very good," a trader in Japan said. PTA operation rates have also dropped sharply while PX operation rates remained on the higher side, sources said. European PTA demand looks subdued for the year, as the end-consumer consumption for PET failed to pick up. Meanwhile, a flurry of Asian exports to Europe could further aggravate the situation. The polyester downstream market showed little signs of improvement this year despite operation rates sharply rising to around 93%. "If you look at polyester chain, sales are not good for whole of last and this week. [Also], PTA margins are low," a PTA producer in North Asia said, adding that the trend could continue in the latter half of the year as well. China's domestic consumption trend looked marginally better, though polyester producers are fighting to clear large stockpiles. High inventories going into the second half of the year could potentially trigger sales at sharp discounts and this could further hurt profitability, the PTA producer said. "They [buyers] saw piles of polyester inventory [so] they want to get discounts [and] they prefer to wait and buy," the producer added.
