Prices of Asia-Pacific's Fertilisers, Petrochemicals Set to Surge on Iran War: ADB

Why It Matters

Rising fertilizer costs threaten food security and lift consumer inflation, while petrochemical price spikes strain manufacturing and plastics supply chains across developing Asia.

Key Takeaways

• Fertilizer prices jumped after Qatar’s QAFCO shutdown.
• Methanol benchmark rose ~25% within two weeks.
• 71% of Thailand’s urea imports come from Middle East.
• Half of Asia’s naphtha imports sourced from Gulf states.
• ADB projects 1.3% growth loss, 3.2% inflation rise.

Pulse Analysis

The escalation of hostilities in the Middle East has revealed a structural vulnerability in Asia‑Pacific supply chains that extends far beyond crude oil. Fertilizer producers such as Qatar’s QAFCO are integral feedstock sources for urea and ammonia, and their production cuts instantly ripple through the region’s agricultural sector. With Thailand and India importing the majority of their urea from the Gulf, even short‑term disruptions translate into higher input costs for staple crops, eroding farm margins and feeding into broader food‑price inflation.

For policymakers, the surge in non‑energy commodity prices compounds the traditional oil‑price shock narrative. ADB’s modeling shows that simultaneous spikes in oil, fertilizer, and petrochemical costs could depress regional GDP by over one percent point while pushing consumer price indices up by more than three points. Lower‑income households, which allocate a larger share of income to food, face heightened vulnerability, prompting calls for targeted subsidies, strategic grain reserves, and diversification of fertilizer sourcing to mitigate the risk of prolonged price volatility.

The petrochemical fallout is equally consequential. Half of the region’s naphtha and a significant share of methanol imports originate from Gulf producers, feeding downstream industries that manufacture plastics, textiles, and chemicals. As benchmark prices climb, manufacturers confront tighter margins and may pass costs onto end‑users, amplifying inflationary pressures. Companies are therefore accelerating efforts to secure alternative feedstocks, invest in regional recycling capacity, and explore green hydrogen‑based ammonia production. Such strategic shifts aim to reduce dependence on geopolitically sensitive imports and bolster supply‑chain resilience in a volatile global environment.
