The Return of Peak Season Surcharges

As the maritime industry transitions into the second quarter of 2026, the era of stable ocean freight rates has officially ended. Major carriers—led by Hapag-Lloyd, Mediterranean Shipping Company (MSC), and CMA CGM—have issued sweeping General Rate Increases (GRI) and Peak Season Surcharges (PSS) effective May 1, 2026. This tactical move signals an early tightening of capacity as global supply chains prepare for the high-volume summer cycle.

For exporters, particularly those serving the Latin American and Trans-Pacific corridors, these increases represent a significant cost escalation. At STU Supply Chain, we have analyzed the raw data from the latest carrier circulars to help our partners mitigate the impact on their bottom line. The current market signals suggest that May will be a pivotal month for cost-governance and space allocation.

Ocean freight cost dynamics entering the 2026 Peak Season.

01. The South America Squeeze: Why ECSA Rates are Spiking

The Latin American trade corridor is witnessing the most aggressive price corrections this season. With Hapag-Lloyd and CMA CGM adding up to $500 per container in surcharges (PSS), the floor price for Brazilian and Argentinian exports has shifted overnight. This is largely driven by a combination of vessel re-deployment to higher-yielding routes and localized port congestion, which has tightened the supply of empty equipment across the region.

Our market unit recommends that shippers with pending South American contracts finalize their bookings before the May 1st cut-off to avoid the $400-$500 "per-box penalty."

02. Asia-Europe & Trans-Pacific: The Capacity Game

For the Asia-to-Europe and Asia-to-US lanes, the rate hikes are being supported by strategic blank sailings. MSC has signaled a 13% increase for Trans-Pacific routes, aimed at absorbing the increased operational costs of the Emergency Bunker Surcharges. In an environment where maritime "Time-to-Market" is increasingly valuable, carriers are leveraging their capacity governance to ensure these new rate levels stick during the Q2 contracting cycle.
