Polymer rally at multi-year highs lacks the freight shock seen in pandemic era

Global polymer markets have largely surged to 4-year highs by the end of March with some even going far beyond to see their highest since 2021, drawing inevitable comparisons to the peaks seen during the pandemic era. Prices across key regions have climbed sharply on the back of supply disruptions driven by the Middle East war and soaring upstream costs, prompting market participants to question whether a similar inflationary cycle is unfolding.

However, despite surface-level similarities in price trajectories, the current rally differs fundamentally from the pandemic-driven surge of 2020–2022, most notably due to the absence of a parallel spike in container freight rates. Current rates are far from logistics crisis times.

Supply-driven rally contrasts with pandemic demand boom

The ongoing uptrend in polymer prices has largely been fueled by supply-side disruptions stemming from escalating geopolitical tensions in the Middle East. Constraints in energy and feedstock flows—including crude oil, LNG, LPG, methanol, and key petrochemical intermediates—have translated into higher production costs and tighter availability across polymer markets.

This dynamic stands in stark contrast to the pandemic period, when polymer price increases were underpinned by a powerful demand surge. Stimulus-driven consumption, a shift from services to goods, and aggressive restocking cycles pushed global trade volumes sharply higher, placing immense strain on logistics networks.

Current rates are far from logistics-crisis times

One of the clearest indicators of the difference between the two periods lies in container freight markets. According to Freightos data, the global freight index traded between highs of around $11,000 per 40-foot container and lows near $4,000 during the 2021–2023 period, reflecting the extreme volatility caused by pandemic-era disruptions.

Following normalization in 2023, freight markets were again tested by the Red Sea crisis and the Panama Canal drought, which pushed rates from around $1,000 to approximately $5,500 per 40-foot container at the peak of the disruptions.

Currently, however, freight rates have eased back to around $1,700, indicating a market that remains far removed from the severe logistics-driven shocks seen in previous crises. While rerouting and longer transit times persist, global shipping networks continue to function without systemic breakdowns.

To put it another way, during those extreme periods, freight rates ranging between $4,000 and $11,000 per 40-foot container translated into roughly $160–445 per ton. At the height of the pandemic, there were instances where ex-China container freight costs alone matched the per-ton value of the polymers being shipped. Today, however, the global index corresponds to only about $65–70 per ton.

Stronger container supply keeps rates in check

Another key factor limiting freight rate increases today is the significantly improved supply side of the container shipping industry. In response to the disruptions experienced during Covid, carriers expanded capacity aggressively through new vessel orders delivered between 2023 and 2025, alongside fleet upgrades and more efficient equipment management.

As a result, the market is now characterized by ample capacity, with overcapacity even emerging on certain trade lanes. This structural shift has placed downward pressure on freight rates, preventing the kind of exponential increases witnessed during the pandemic.

Weaker demand caps upside potential

Demand conditions also differ sharply from those seen in 2020–2022. Instead of a consumption boom, markets today are marked by cautious buying behavior, tighter financial conditions, and limited restocking appetite. Many players remain reluctant to commit to large volumes, which in turn constrains the ability of suppliers to sustain aggressive price hikes.

A different kind of inflation cycle

Taken together, the current market environment points to a cost-driven inflation cycle rather than a systemic logistics crisis. While supply disruptions in the Middle East have created upward pressure across the petrochemical chain, they have not triggered a comparable surge in freight markets.

For polymer markets, this distinction is crucial. Without the amplifying effect of logistics bottlenecks and in the presence of weaker demand and ample shipping capacity, the current rally—though strong—remains fundamentally different from the pandemic-era spike.
