How large are the June 1 rate increases compared to mid-May levels?
Pricing on both the U.S. East Coast and West Coast transpacific eastbound lanes is running approximately 30% to 45% above May 15 spot market levels following the confirmed GRIs. On separate trade lanes, Maersk implemented its own peak season surcharge effective June 4 on Far East-to-East Coast South America routes, adding $1,000 per 20-foot container and $2,000 per 40-foot container, while CMA CGM layered new peak season surcharges on Asian routes serving the Caribbean and Manaus following its own June 1 GRI on South American exports.
| Carrier | Action | Lane | Amount/Level |
|---|---|---|---|
| ONE | Peak Season Surcharge | Transpacific eastbound | $2,000/FEU, effective June 1 |
| MSC | General Rate Increase | Mediterranean/Black Sea | Quotes exceeding $5,700/FEU |
| Hapag-Lloyd | General Rate Increase | Mediterranean/Black Sea | Rates past $5,200/FEU |
| Maersk | Peak Season Surcharge | Far East to East Coast South America | $1,000/20ft, $2,000/40ft, effective June 4 |
| CMA CGM | GRI + PSS | South American exports; Asia-Caribbean/Manaus | New surcharges layered on June 1 GRI |
- Multiple carriers confirming GRIs and PSS on the same effective date (June 1) across different trade lanes suggests coordinated capacity discipline rather than lane-specific pricing actions
- The 30-45% increase over mid-May spot levels on transpacific eastbound is a substantial single-cycle jump, consistent with reporting of an unusually early and aggressive 2026 peak season
- Layered GRI-plus-PSS structures (as seen with CMA CGM and Maersk) mean total surcharge exposure on some lanes is compounding rather than additive to a single rate action
Why are carriers pushing rate increases across so many lanes simultaneously?
The breadth of June 1 actions — spanning transpacific, Mediterranean, Black Sea, and South American lanes — points to carriers using a favorable demand window (driven by tariff-related frontloading and early peak season booking activity) to push through increases across their networks at once, rather than waiting for lane-specific negotiating leverage. Carriers historically move in loose coordination on GRI timing because rate increases are harder to enforce unilaterally without broad industry participation.
What Shippers Should Do
- If your contracts allow renegotiation, confirm whether your specific carrier and lane were part of the June 1 wave before accepting a quoted increase — not every lane saw the same magnitude of increase.
- For lanes with layered GRI-plus-PSS exposure (South America, Mediterranean), request an itemized rate breakdown rather than a single blended quote, since the surcharge stack can obscure how much of the increase is GRI versus PSS.
- Where booking flexibility exists, consider locking in space before the next confirmed rate action — carriers signaling coordinated increases on one date often follow with further actions at the next GRI cycle if demand holds.
- Track GRI and PSS announcements by lane on ANKPOST Pulse to anticipate the next rate action before it's formally confirmed by your carrier.
