Plastic Prices Set to Jump in Thailand by April as Middle East Crisis Disrupts Supply

Thailand's petrochemical supply chain is under strain as escalating Middle East hostilities disrupt crude oil flows, triggering plastic shortages and price hikes that will ripple through everything from instant noodle packaging to paint production by April.

Why This Matters:

• Price hikes imminent: Plastic packaging costs—including bags, bottles, and films—expected to jump in April as raw material costs surge.

• Production halts: SCG's Rayong Olefins plant has declared force majeure and suspended operations due to naphtha and propane shortages.

• Diesel could hit ฿60/liter: If the Strait of Hormuz closes, retail fuel prices in Thailand may exceed ฿60 per liter, with Brent crude potentially reaching $150–200 per barrel.

• Reserve cushion limited: Thailand holds roughly 60 days of oil reserves—a buffer that may prove insufficient if conflict extends beyond three months.

The Supply Shock Taking Shape

The Thailand Ministry of Energy and Ministry of Industry are monitoring the situation closely as hostilities between the United States, Israel, and Iran—which intensified in late February—continue to disrupt global energy flows. Nearly 2,000 casualties have been reported, and the threat of a prolonged closure of the Strait of Hormuz, through which 20% of global oil transits, has sent Brent crude above $80 per barrel, up 30% from January lows. Some forecasts place the risk ceiling at $120–150 per barrel if shipping lanes remain blocked.

For Thailand, which sources more than 51% of its crude and naphtha imports from the Middle East, the implications are immediate. Naphtha—the feedstock for petrochemical production—has jumped 12.5% in Europe and 19.6% in North America during March alone. Bank of America now projects Brent averaging $77.50 per barrel for 2026, with second-quarter prices hovering near $80 and potential spikes to $100–130 if disruptions persist.

Factories Go Dark, Stocks Run Low

SCG's Rayong Olefins plant, operated by Rayong Olefins Company Limited, has invoked force majeure and temporarily halted production, citing its inability to secure sufficient naphtha and propane—the primary inputs for olefins. The shutdown has cascaded downstream, leaving manufacturers of plastic pellets scrambling to meet demand.

TOA Paint (Thailand) Public Company Limited disclosed that it now holds just 20 days of raw material inventory and expects first-quarter 2026 profits to contract. Meanwhile, Thai President Foods Public Company Limited, the producer behind the iconic "Mama" instant noodles, is rationing film suppliers' orders and prioritizing high-volume SKUs as packaging material becomes scarce. Suppliers of hot-fill bags, high-density polyethylene (HDPE) bags, PET bottles, and plastic straws have notified clients of price adjustments effective April, citing pellet shortages and energy cost inflation.

The Plastics Industry Club of the Federation of Thai Industries warns that low-margin packaging segments will bear the brunt, with price increases certain by April. The Thailand Ministry of Energy has instructed PTT Public Company Limited to source additional feedstock to cushion price shocks, while insisting that domestic pellet supply has not yet hit critical levels—though factories may slow or suspend operations if margins collapse.

What This Means for Residents

Anyone living in Thailand will feel the squeeze in everyday purchases. Packaged goods—from beverages in PET bottles to instant meals in plastic sleeves—are set to become pricier. Retailers and food manufacturers, already operating on thin margins, will face difficult choices: absorb rising costs or pass them to consumers. The latter appears more likely.

Srichand United Dispensary Limited, a cosmetics producer, has pre-emptively stockpiled raw materials to lock in current prices and avoid passing increases to customers. But smaller operators lack that buffer. The Thailand Cabinet and Ministry of Industry are preparing emergency support measures, including subsidies for energy-efficient equipment upgrades and working-capital assistance for SMEs hit by logistics and energy inflation.

If the conflict drags beyond three months, Kasikorn Research Center estimates Thailand's GDP could contract by 0.6%, with headline inflation climbing 1 percentage point due to energy costs. Tourism and export sectors would also take hits. Some analysts warn of stagflation risk—high inflation coupled with economic stagnation—given Thailand's heavy reliance on Middle Eastern energy imports.

Searching for Alternatives

Recognizing the vulnerability, the Thailand Board of Investment (BOI) has doubled down on incentives for bioplastics and circular economy models under the Bio-Circular-Green (BCG) framework. Projects producing biodegradable polymers such as Polylactic Acid (PLA) from domestic sugarcane are now eligible for enhanced tax breaks. The BOI's 2026 stimulus package offers an additional 50% corporate income tax reduction for five years for mega-projects worth at least ฿2,000 M, excluding land and working capital.

The "Green Plas Pallet" initiative, a public-private collaboration, aims to recycle 1 M tons of plastic waste by 2030, converting post-consumer plastic into composite lumber for warehouse pallets and industrial transport. The Thailand Revenue Department is also weighing a plastic tax to incentivize recycled-content mandates, though implementation timelines remain unclear.

Yet bioplastics remain 2–3 times more expensive than conventional resins, limiting adoption to large hotels, restaurants, and beverage chains willing to pay a sustainability premium. For mass-market manufacturers, the economics don't yet pencil out.

A Temporary Storm or Structural Shift?

The BOI insists that overall investment sentiment in Thailand remains intact, despite sector-specific turbulence. The board's retention and expansion program, valid through the end of 2027, offers incremental tax relief to companies that commit to keeping or enlarging production bases in Thailand. Separately, the Thailand Ministry of Energy is leveraging the Oil Fuel Fund to temporarily cap diesel prices, though that mechanism has limited firepower if crude stays elevated for months.

Shipping disruptions compound the squeeze. Major carriers have rerouted vessels around the Cape of Good Hope to avoid the Red Sea and Strait of Hormuz, adding more than a month to transit times and pushing container rates up 15–20% on some lanes. Insurance premiums and freight charges have surged 50–140%, further inflating landed costs for imported petrochemicals.

The Road Ahead

By April, Thailand-based food, beverage, and cosmetics manufacturers will face a new cost structure. Those with forward contracts or large inventories will weather the storm; those without will scramble. The Thailand Plastics Industry Club expects supply tightness to persist through the second quarter, with relief contingent on a ceasefire or the unlocking of alternative supply routes.

In the longer term, Thailand's push toward recycled PET (rPET) and bio-based polymers may accelerate. The government's National Plastic Waste Management Action Plan (2018–2030) targets 100% recycling of plastic waste by 2027 and the phase-out of single-use plastics including thin carrier bags, foam containers, and straws. Starting January 2025, Thailand banned imports of plastic scrap under HS code 39.15, aiming to reduce environmental impact and reliance on foreign waste streams.

For now, though, the immediate reality is tighter supply, higher prices, and a scramble for alternatives. The Thailand Ministry of Industry and BOI are betting that incentives for green technology, recycling infrastructure, and bioplastic clusters will soften the blow and position the country as a regional hub for sustainable materials. Whether that transition happens fast enough to offset the current crunch remains an open question.

Diagonal readers should note: The conflict has already moved from theory to practice—force majeure declarations, 20-day inventory buffers, and April price hikes are not projections but current realities. Anyone managing supply chains, budgeting for consumer goods, or planning capital expenditure in Thailand needs to factor in a new baseline for petrochemical costs and availability. The 60-day oil reserve cushion offers breathing room, but not indefinitely.
