Asia Methanol Prices Reset Higher as Iran-Linked Supply Shock Reshapes Regional Trade

Epignosis Insights, a Global Market Research and publishing firm, today released its latest Asia Methanol Price Tracker, documenting how the region's methanol market has moved from a year of unusual price stability into its sharpest supply shock in at least four years — and why the aftershocks are still shaping regional benchmarks months later.

A Historic Supply Shock Redraws the Asia Methanol Price Map

According to the report, CFR Southeast Asia methanol prices held in a narrow $315–325 per tonne band from August 2025 through late February 2026. That calm ended abruptly on February 28, 2026, when the outbreak of the U.S.–Israel conflict with Iran triggered an effective closure of the Strait of Hormuz, cutting off Iranian methanol supply that had been meeting a substantial share of Asian demand. By March 20, 2026, CFR Southeast Asia prices had jumped 72% to $555 per tonne, the highest level since March 2021, while CFR China prices rose 46.5% over the same three-week window to $381 per tonne. The strain was already visible before the conflict: China's first-half 2025 methanol imports fell 14.7% year-on-year to 5.377 million tonnes, as overseas plant operating rates outside China averaged just 58%.

China and Southeast Asia Diverge Sharply

The report highlights the regional divergence between China and Southeast Asia as the defining feature of this cycle. China entered the crisis with a lower price base CFR China spot was assessed at $240 per tonne in December 2025 and Chinese buyers were comparatively insulated because local participants held an estimated eight weeks of inventory, with several Iran-origin cargoes already en route when the conflict began. 

Southeast Asia, South Korea, and Taiwan carried no equivalent buffer, and alternative suppliers in Saudi Arabia and Qatar could not reroute cargoes fast enough to close the gap. The CFR China-to-CFR-Southeast-Asia spread widened to $174 per tonne by late March, briefly reopening an arbitrage window in which China became a source of re-exported cargoes rather than solely an importer.

Anatomy of the Disruption and Its Company-Level Impact

Iran's outsized role in seaborne methanol trade sits at the center of the shock. The report notes Iran is the world's second-largest methanol producer, with 17.16 million tonnes of annual capacity, exporting roughly 90% of that output through the single port of Assaluyeh. That concentration left the market acutely exposed once the March 18, 2026 strike on Iran's South Pars gas field disrupted the feedstock underpinning production. Iran-origin methanol shipments to China fell to just 80,000 tonnes for the entire month of March, while an estimated 18% of global methanol production capacity was affected by the broader disruption to crude, naphtha, and petrochemical feedstock flows through the strait.

The company-level data adds further texture. Methanex Corporation, the world's largest methanol producer, saw its global average realized price fall from $400 per tonne in the first quarter of 2025 to $351 per tonne in the first quarter of 2026, before jumping to $529 per tonne in the second quarter of 2026 driving the company's best quarterly results on record. Methanex has guided average realized prices for July and August 2026 to a range of $460–485 per tonne, a step down from the Q2 peak but still well above pre-conflict levels. Separately, the company disclosed it would indefinitely idle its Titan facility in Trinidad and Tobago, taking a $115 million non-cash impairment charge, after concluding the plant's gas supply economics no longer supported continued operation.

Regional Spillover Beyond China

The disruption extended well beyond China and Southeast Asia. CFR India methanol prices hit an over-four-year high as Iranian shipments which typically supply a large share of India's formaldehyde and pharmaceutical-sector demand were curtailed. South Korean prices reached a 53-week high on March 13, 2026, ahead of the broader regional peak, while Taiwan prices climbed to their highest level in four and a half years. Notably, China's formula-priced Iranian cargoes, which historically trade at a premium to benchmark Chinese methanol prices, slipped to a discount of roughly 2% versus parity during the disruption, temporarily inverting price relationships that normally hold across the region.

“The Asia methanol market has not returned to its pre-conflict baseline, and our data suggests procurement teams should treat current price levels as the working range for the near term rather than a transition point back to pre-crisis pricing.” 

Outlook: Elevated Pricing Likely to Persist Through 2026

Looking ahead, the Epignosis Insights Research Desk expects continued, if reduced, disruption to global methanol trade. Total global methanol trade volume in 2026 is projected to come in below the roughly 40 million tonnes per year that held steady from 2023 through 2025, driven by the ongoing Middle East conflict's effect on the world's largest exporting region. A June 2026 memorandum of understanding between the U.S. and Iran briefly restored some shipping activity, but renewed Iranian attacks on shipping deemed non-compliant resumed in July 2026, and China's domestic futures have not returned to their pre-conflict lows since. By August 13, 2026, China's domestic methanol futures contract had settled at 2,636 yuan per tonne still 12.65% above year-ago levels.

Beneath the near-term volatility, the report finds the longer-run demand picture remains China-centric and modestly expansionary, with the Methanol Institute expecting global methanol demand growth to return to an average annual rate of 2.5% to 3.0% in the coming years, up from under 1% between 2020 and 2025. That combination heavy import dependence for marginal supply, concentrated Middle Eastern export exposure, and a large, price-sensitive MTO demand base — is a structural feature of the Asian methanol market rather than a one-off consequence of the current conflict.
