Polymer rally at pandemic-era highs in just 6 weeks; what happens next?

Global polymer markets have surged to their highest levels since the pandemic across most regions and products, with several grades particularly in the PE group already exceeding those peaks, according to ChemOrbis Price Index. Yet what makes the current rally remarkable is not just the level reached — but the speed at which it has unfolded.

During the pandemic, it took nearly nine months for polymer prices to climb to their historic highs - in some cases it took much longer depending on the product/market combination, supported by a prolonged cocktail of stimulus-driven demand, logistics bottlenecks, and gradual supply tightening. In contrast, the latest rally has compressed this entire cycle into just six weeks, following the eruption of war between the US-Israel and Iran, which severely disrupted supply flows from the Middle East.

As markets move through the seventh week, attention is shifting from the magnitude of the rally to its sustainability, particularly as ceasefire talks continue to falter and resume intermittently.

Key distinction between the two cycles: Pandemic rally was built on demand

The key distinction between the two cycles lies in the underlying driver.

In 2020–2021, the rally was largely demand-led, fueled by post-lockdown restocking, fiscal stimulus, freight rally, and strong consumption across downstream sectors. Supply constraints, while significant, emerged gradually and amplified an already robust demand environment.

Today’s rally, however, is fundamentally supply-driven

The closure or disruption of critical Middle Eastern production hubs, coupled with logistical bottlenecks, insurance premiums, and restricted tanker movements through the Strait of Hormuz, has sharply curtailed export availability.

At the same time, demand remains fragile, with converters increasingly resistant to absorbing rapid cost increases, leading to widening gaps between bids and offers and declining market liquidity.



Faster, sharper — but more fragile

The accelerated pace of the current rally also highlights a more fragile market structure.

Rather than a broad-based expansion supported by consumption, price increases have been driven by availability concerns and replacement cost pressures. This has pushed several markets, including Türkiye, into premium territory against Asia,reopening arbitrage discussions without yet generating consistent trade flows. In the meantime, European PE markets have even exceeded the pandemic peaks, hitting all-time highs recently, while other products including PP and PET are around their 4-year highs. Likewise, Southeast Asia markets saw their highest levels of the past four years in PP and LDPE while HDPE and LLDPE posted sharper gains to reach levels not seen since late 2014, according to ChemOrbis Price Index.

The result is a market that has reached extreme levels quickly — but without the demand cushion that characterized the pandemic cycle.

Even if the war ends, normalization may lag

A growing consensus is emerging that even a de-escalation in geopolitical tensions may not immediately translate into easing supply conditions.

Several factors could delay normalization:

• Gradual restart of production units: Facilities operating at reduced rates or shut as a precaution may require time to return to full capacity. Some analysts even suggest 12-18 months to return to normal.


• Logistics and vessel repositioning: Tankers and container flows disrupted during the conflict will need time to rebalance, particularly if alternative routes were used.


• Insurance and risk premiums: Elevated war risk premiums are unlikely to disappear overnight, keeping freight and transaction costs elevated.


• Cautious seller strategies: Producers may maintain tight allocation policies until stability is firmly established.


• Inventory gaps across import markets: Buyers that delayed purchases during peak uncertainty may re-enter simultaneously, sustaining tightness even as supply improves.

What will break the cycle?

As the market enters its seventh week, the key question is no longer how high prices can go — but what will bring them down.

Will demand destruction finally gain traction as converters resist further increases?
Or will lingering supply constraints and logistical frictions continue to underpin prices, even in a post-conflict scenario?

Unlike the pandemic rally, where the path was shaped by expanding demand, the current cycle may ultimately be decided by how and when supply chains normalize — a process that could prove more uneven than expected.
