Geopolitical tensions in the Middle East are introducing new variables, leading to a shift in market expectations for paraxylene (PX), purified terephthalic acid (PTA), and monoethylene glycol (MEG).

Primary Viewpoint for PX/PTA

Core Perspective: Moderately Bullish

Multiple PX and PTA units have entered maintenance in July, with PX operating rates at 72.95% and PTA at 52.35%, placing supply in a low range. On the demand side, downstream orders are limited during the off-season. However, as raw material costs rebound, sales volumes for polyester staple fiber and filament yarn have shown signs of increasing, alleviating inventory pressure at polyester plants and creating conditions for higher operating rates.

Strategy: Follow the crude oil rebound unilaterally. With renewed concerns over the Strait of Hormuz blockade, market focus has shifted back to uncertainties in Middle Eastern feedstock supply. A potential naphtha shortage could impact PX operations both domestically and internationally. Monitor opportunities for a 9-1 calendar spread on PX or PTA.

Valuation: Moderately Bullish. The PX-naphtha (PXN) spread has declined, PTA processing margins have weakened, and profits across the polyester product chain have generally narrowed. With rising upstream costs, valuations within the polyester industrial chain are under compression.

Cost: Moderately Bullish. Renewed tensions between the US and Iran, with Iran threatening another blockade of the Strait of Hormuz, have caused a spike in geopolitical risk premiums, temporarily boosting crude oil prices. Crude is expected to remain volatile with an overall strong bias, though the sustainability of the rally is uncertain. Medium to long-term support may come from seasonal refinery restocking and Strategic Petroleum Reserve (SPR) replenishment.

Supply Dynamics

Supply: Moderately Bullish

PX: Domestically, Sinochem Quanzhou's 800k tonne unit reduced rates in late June but has now recovered. The restart of Yangzi Petrochemical's unit, initially planned for early July, has been postponed. Monitor the planned late-July restart of Fuhaichuang. Overseas, PTTG's 770k tonne unit recently shut for maintenance, expected to last around 40 days. Domestically, Fuhaichuang and Weilian Chemical are scheduled to restart in late July.

PTA: This week, Yisheng Hainan's 2.5 million tonne unit restarted, while another 2 million tonne unit began maintenance on July 9. The 700k tonne unit at Taiwan's China American Petrochemical Co. restarted on July 13. Sichuan Nengtou, Fuhaichuang, and Zhongtai Chemical are expected to restart in late July.

Demand and Inventory

Demand: Moderately Bullish. Restarts at Fuhai, Hengli, and Hanjiang, along with increased operating rates for bottle chip and filament yarn production, have driven a slight uptick in overall polyester operating rates. Approaching the peak season and coupled with rising costs, improved sales for staple fiber and filament yarn are helping polyester plants reduce inventories.

Supply-Demand Balance: Neutral. PX and PTA operating rates have reached historically low levels, while polyester operating rates have edged up slightly, leading to accelerated destocking of PTA social inventories in the near term. Expectations for restarts of maintenance units at month-end persist, spot liquidity remains adequate, and the PTA basis has retreated from recent highs.

Primary Viewpoint for MEG

Core Perspective: Moderately Bullish

The renewed blockade of the Strait of Hormuz continues to delay the recovery of imports, with no clear signs of restoration yet. Domestic production has seen a slight reduction, with narrowing margins for coal-based units leading to increased maintenance at previously unaffected plants. Demand remains subdued in the off-season. However, rebounding raw material costs have spurred sales of staple fiber and filament yarn, easing inventory pressure and supporting higher operating rates at polyester plants. Looking ahead to Q4, several new MEG plants are scheduled to start, with pressure primarily reflected in the January contract, establishing a near-term strong, long-term weak pattern.

Strategy: In the near term, influenced by Middle East geopolitics, imports are likely to fall short of expectations; maintain existing long positions. Consider a 9-1 calendar spread on dips.

Valuation: Moderately Bullish. Surging oil product prices have lifted MEG prices, compressing naphtha-based production margins while significantly improving coal-based production profits.

Supply: Moderately Bullish. As of July 10, the overall operating rate for MEG in mainland China was 53.27%, down 3.31 percentage points week-on-week. Ethylene-based capacity utilization stood at 50.09% (down 0.75 p.p.), while non-ethylene-based MEG operating rates were 58.77% (down 4.5 p.p.).

Imports: Bullish. The renewed blockade of the Strait of Hormuz creates uncertainty for the recovery of MEG imports from the Middle East, with no visible restarts of related units yet. The timeline for import recovery has been pushed back.

Demand: Moderately Bullish. Similar to PTA/ PX, restarts at Fuhai, Hengli, and Hanjiang, along with higher bottle chip and filament yarn rates, have lifted polyester operating rates. The approaching peak season and rising costs are driving sales and inventory reduction at polyester plants.

Supply-Demand Balance: Bullish. Fluctuating US-Iran tensions have delayed the reopening of the Strait of Hormuz. Import recovery will take time, leading to expectations of significant MEG inventory drawdowns in Q3. Fundamentals are expected to tighten further, supported by low import levels.

Price, Spread, and Margin Analysis

The PX 9-1 calendar spread has bottomed and begun to rise. Renewed US-Iran tensions and the threat to the Strait of Hormuz have injected a geopolitical risk premium, temporarily lifting crude oil prices amid strong volatility. The rally's sustainability is uncertain. Medium-term support may come from seasonal refinery and SPR restocking.

Naphtha prices followed crude lower initially but have since risen. The Japan CFR price stands at $731/tonne, up $67.75 or 10.21% week-on-week.

PX CFR Taiwan is at $1016.67/tonne, up $44 or 4.52% week-on-week.

The PXN spread has continued to narrow to $285.67/tonne, down $23.75 week-on-week. The PX-MX spread also fell significantly, though short-process PX production margins improved to $141.67/tonne, up $22 week-on-week.

Gasoline crack spreads in the US, Europe, and Asia have rebounded sharply. Asian naphtha crack spreads have also recovered, supported by ongoing geopolitical risk premiums from Strait of Hormuz instability and tightening supplies outside Asia, which are underpinning buyer demand.

The chemical economics for mixed xylenes and toluene have changed little.

The PTA basis and calendar spreads have weakened, with spot processing margins retreating from highs. The PTA basis fluctuated this week, starting around +255~260 over the September contract, peaking mid-week, and weakening to around +230 by Friday afternoon. Weekly average processing margins remained high at 632 yuan/tonne. On July 13, the main PTA futures contract closed at 5612 yuan/tonne, up 150 yuan or 2.75% week-on-week.

Both the MEG basis and the 9-1 calendar spread strengthened. Prices rose from lows early in the week, with the basis firming amid active trader buying ahead of expected typhoon-related port closures. Mid-week, geopolitical tensions spurred a sharp crude oil rally, lifting chemical commodities. Expectations for reduced overseas MEG supply due to the Strait of Hormuz situation further boosted sentiment. By Friday, spot MEG traded as high as 4410-4420 yuan/tonne. On July 13, the main MEG futures contract closed at 4359 yuan/tonne, up 354 yuan or 8.84% week-on-week.

Profits for all polyester products have declined.

Supply, Demand, and Inventory Details

Polyester capacity growth in 2026 is projected to be higher than in 2025, with new capacity estimated at 5.47 million tonnes, representing a 6.14% growth rate. Following significant bottle chip capacity additions in 2024-2025 which pressured margins, 2026 will see fewer new bottle chip projects—only 700k tonnes from Fuhai and Kesen New Materials. Filament yarn, which saw less capacity growth in prior years and enjoyed improved margins, will be the main driver of 2026 expansions, with 800k tonnes expected in Q1 and 1.01 million tonnes from April-May. If bottle chip margins continue to improve, new projects from Hanjiang and Anhua may proceed.

Polyester operating rates increased slightly. As of July 10, the overall rate was 79.7% (+1.1 p.p.), with filament yarn at 74.2% (+0.7 p.p.), staple fiber at 77.4% (+2.1 p.p.), and bottle chips at 72.3% (+1.8 p.p.).

From January to May, net polyester exports totaled 6.207 million tonnes, up 4.5% year-on-year. This included 2.701 million tonnes of bottle chips (+0.17% YoY), 1.838 million tonnes of filament yarn (+7.5% YoY), and 711k tonnes of staple fiber (+6.3% YoY).

Polyester product inventories decreased across the board. Staple fiber inventory days fell to 8.44 days (-0.65 days). Filament yarn inventory days also dropped: DTY to 37.3 days (-4.3 days), FDY to 32.5 days (-3.9 days), and POY to 26.4 days (-5.1 days). Polyester chip inventory fell to 6.45 days (-1.7 days), and bottle chip inventory to 9.2 days (-1.4 days).

The sales-to-production ratio improved for staple fiber and filament yarn. The five-day average for staple fiber was 79.6% (+14.6 p.p. WoW), for filament yarn 55.3% (+6.8 p.p. WoW), and for chips 60.8% (+13.2 p.p. WoW).

Finished goods inventory days and raw material (polyester yarn) stockpile days both decreased. As of July 9, finished fabric inventory averaged 17.29 days (+0.44 days WoW). The market is clearly in a seasonal lull, with slow sales of conventional fabrics. Summer orders have mostly concluded, leaving only small replenishment orders. High inventory in the intermediate fabric segment limits restocking willingness, and procurement slowed further after the recent crude oil price drop. Raw material (polyester yarn) inventory at weaving mills averaged 10.80 days (+2.23 days WoW). Later in the week, rising oil prices and polyester feedstock costs prompted mills to make necessary purchases, but overall demand remains weak with only small, short-term orders supporting the market.

Downstream order intake is average. As of July 10, operating rates were: warp knitting 46.2% (-0.2 p.p.), air-jet weaving 53.2% (flat), water-jet weaving 58.8% (-0.3 p.p.), circular knitting 36.2% (-1.7 p.p.), and dyeing 50.7% (flat). As of July 9, average order days for weaving stood at 7.97 days (-0.66 days WoW). The traditional off-season is deepening, with orders mainly consisting of small replenishments. Summer orders have ended, while autumn/winter orders have not yet been placed, except for decent sales in sportswear, outdoor, and sun-protection fabrics. Home textile orders are平淡, mostly small and short-term.

PX Supply and Demand

New PX capacity in 2026, totaling 3.97 million tonnes (9.1% growth), is concentrated in the second half. This includes Fujia Dahua's 300k tonne expansion, Huajin's 2 million tonnes, and Jiujiang Petrochemical's 1.5 million tonnes (possibly delayed). Fujia Dahua's expansion will come online early in the year. After Jinling Petrochemical's restart in late May, its capacity increased by 170k tonnes to 870k tonnes. Huajin's project is slated for Q3 2026, and Jiujiang's for Q4, meaning supply pressure will mainly emerge in Q4. Shandong Yulong Petrochemical's 3 million tonne unit can only produce MX for now, as it lacks PX production approval, likely pushing its start to 2027. Overseas, only Indian Oil Corporation's 800k tonne unit is expected in H2 2026, primarily to feed its downstream PTA plant.

Both domestic and overseas PX operating rates have declined. Domestically, Sinochem Quanzhou has recovered from a late-June rate cut. Yangzi Petrochemical's restart is delayed. Monitor Fuhaichuang's late-July restart plan. Overseas, PTTG's 770k tonne unit is under maintenance.

The domestic PX operating rate is 62.58% (-10.37 p.p. WoW). The Asian PX operating rate is 59.72% (-4.21 p.p. WoW). Domestic PX production in June was 2.897 million tonnes, down 2.1% month-on-month and 10.2% year-on-year.

PX imports in May were 482k tonnes, down 30.6% month-on-month and 37.7% year-on-year. Cumulative imports for Jan-May were 4.02 million tonnes, up 7.6% year-on-year.

PTA Supply and Demand

There are no new PTA capacity additions planned for 2026. Several units with a combined capacity of 2.625 million tonnes have been idled for over two years with no restart plans and are thus excluded from the capacity base. Effective January 1, 2026, China's PTA nameplate capacity is adjusted to 92.09 million tonnes, alleviating near-term capacity pressure.

PTA production in June was 5.518 million tonnes, up 3.8% month-on-month but down 12.3% year-on-year. Cumulative production for Jan-Jun was 35.839 million tonnes, up 0.3% year-on-year.

PTA exports in May were 326.1k tonnes, up 12.1% month-on-month and 23% year-on-year. Cumulative exports for Jan-May were 1.533 million tonnes, down 4.3% year-on-year.

Domestic PTA operating rates remain low. Yisheng Hainan's 2.5 million tonne unit restarted, while another 2 million tonne unit began maintenance on July 9. The 700k tonne unit at Taiwan's China American Petrochemical Co. restarted on July 13. The overall PTA operating rate is 52.88% (+0.53 p.p. WoW).

Warehouse receipt volumes have retreated from highs. Social inventories have continued to draw down significantly. As of July 10, total PTA social inventory was 2.282 million tonnes, down 144k tonnes week-on-week. This decrease comprised a 95-tonne drop in warehouse receipts, a 71k tonne reduction in port/warehouse stocks, a 69k tonne decline in PTA plant inventories, and a 3,382-tonne decrease in polyester plant inventories.

MEG Supply and Demand

New MEG capacity additions in 2026, totaling 2.75 million tonnes (primarily oil-based), are concentrated in Q4, representing a 9.2% growth rate. BASF's unit started early in the year, while the other three projects are slated for Q4, creating a capacity addition gap in Q2-Q3.

MEG production in June was 1.55 million tonnes, down 8.6% month-on-month but up 1.5% year-on-year. Cumulative production for Jan-Jun was 9.956 million tonnes, up 2.2% year-on-year.

Maintenance has increased for coal-based MEG units, leading to a sharp drop in non-ethylene-based operating rates. As of July 10, the overall operating rate was 53.27% (-3.31 p.p. WoW). Ethylene-based utilization was 50.09% (-0.75 p.p.), and non-ethylene-based was 58.77% (-4.5 p.p.). Specific maintenance schedules include units at Gulei Petrochemical, Hengli, Shenghong Refining, Xinjiang Tianye, Yangmei Shouyang, Hongsifang, Inner Mongolia Yankuang, Woneng, Guanghui, Meijin, Zhonghuaxue, and Zhengdakai across July and August. Surging oil product prices have lifted MEG prices, compressing naphtha-based margins but significantly improving coal-based profits.

MEG imports in May were 200k tonnes, down 43.7% month-on-month and 66.9% year-on-year. Cumulative imports for Jan-May were 2.457 million tonnes, down 23.9% year-on-year.

Port inventories for MEG continue to decline. As of July 10, inventories at East China main ports were 428k tonnes, down 51k tonnes week-on-week. Expected arrivals are slightly higher at 54k tonnes, while outflows have decreased slightly.

MEG plant inventories increased significantly month-on-month in June to 480k tonnes (+30k tonnes MoM, +171k tonnes YoY). Polyester plant MEG feedstock stockpile days increased slightly to 13.8 days (+0.3 days WoW).

Supply-Demand Balance Forecasts

PX Monthly Balance Forecast: Entering Q2, PX units reduced rates alongside refineries due to limited crude supply, though the decline was modest and rates remained high year-on-year. Downstream, PTA entered a concentrated maintenance season from April, with some plants facing feedstock shortages, pushing PTA rates to multi-year lows and marginally easing PX fundamentals. In June and July, maintenance at major units like Shenghong and Weilian Chemical will push operating rates to annual lows, tightening the PX balance. In Q4, with new capacity start-ups and the downstream off-season, PX inventories are expected to build.

PTA Monthly Balance Forecast: In Q2, PTA units faced seasonal maintenance and production cuts due to insufficient PX feedstock, a situation persisting into July. Exports are down year-on-year due to new overseas capacity. Fundamentals point to significant inventory drawdowns in May, June, and July, with the pace slowing in August. In Q4, with supply recovery and the off-season, the market is expected to shift into inventory accumulation.

MEG Monthly Balance Forecast: Entering Q3, uncertainty surrounding US-Iran tensions and the Strait of Hormuz means import volumes will likely remain low. Domestically, increased maintenance at non-ethylene-based MEG units and declining margins have pushed operating rates lower from highs, limiting overall production growth quarter-on-quarter. Assuming the Strait of Hormuz reopens in August, imports could begin a slow recovery in September, coinciding with higher polyester operating rates and restocking. Fundamentals suggest continued inventory drawdowns in Q3.
