Iran Conflict Keeps Trans-Pacific Rates High Despite Low Demand
The ongoing Iran conflict and U.S. blockade of the Strait of Hormuz are creating an unusual market dynamic on trans-Pacific shipping lanes: elevated container rates during a period of traditionally low demand. Asia-U.S. West Coast spot rates climbed to $2,675/FEU (up 1%), while East Coast rates reached $3,939/FEU (up 3%), buoyed by higher fuel costs despite what should be the year's lowest-price season. This contradicts Asia-Europe lanes, where rates have largely stabilized near pre-war levels, suggesting regional supply-demand imbalances rather than a purely geopolitical story. For supply chain professionals, this presents a strategic puzzle: shippers face elevated costs during a cyclically weak period, which may squeeze margins and discourage peak-season volume commitments. The Freightos Baltic Index and SONAR data show rates have climbed 45% on the West Coast and 30% on the East Coast since late February, but remain 15-20% below earlier Red Sea disruption spikes. Carriers are managing capacity through blanked sailings and GRI cancellations on Asia-Europe, signaling confidence that demand pressure will ultimately cap rate gains. Looking ahead, supply chain teams should prepare for potential June-July peak season volatility. Elevated energy costs could dampen consumer demand, creating a mismatch between available capacity and actual shipper volume. The confluence of geopolitical uncertainty, bunker fuel volatility (Brent crude hit $121/barrel), and diesel surcharges ($5+/gallon) suggests that operational planning must now account for sustained higher transportation costs as a structural feature, not a temporary shock.
The Iran Conflict Paradox: Low Demand, High Prices
Most supply chain professionals know the seasonal script by heart: late February through May is the quiet season in containerized ocean shipping. Demand typically retreats after Chinese New Year celebrations, inventory builds have wound down, and the Northern Hemisphere hasn't yet shifted into summer consumption patterns. Pricing in this window usually reaches annual lows—a relief for importers' budgets after the chaos of peak season. Yet 2024 is breaking that pattern.
The ongoing U.S. military blockade of the Strait of Hormuz, triggered by the Iran conflict, has upended traditional seasonality. Asia-U.S. West Coast spot rates have climbed to $2,675 per 40-foot equivalent unit (FEU), up 1% week-over-week, while East Coast rates have jumped 3% to $3,939/FEU. More strikingly, since the conflict erupted on February 28, West Coast rates have surged 45% and East Coast rates 30%—remarkable gains for what should be the industry's doldrums. The culprit is straightforward: fuel costs. Brent crude has hit $121/barrel for June contracts, and U.S. diesel now trades north of $5 per gallon. Ocean carriers, whose bunker fuel costs directly drive profitability, are passing these expenses to shippers regardless of demand conditions.
A Tale of Two Regions: Why Trans-Pacific Differs From Europe
The market dynamics reveal something important about trade lane economics. While trans-Pacific rates remain elevated, Asia-Europe routes tell a different story. North Europe rates sit at $2,668/FEU (only 8% above pre-war levels) and Mediterranean rates at $3,527/FEU are actually 3% lower than late February. Maersk has cancelled its Asia-Europe general rate increase (GRI), and carriers are deploying blanked sailings to right-size capacity.
This divergence exposes a critical distinction: geopolitical costs are global, but demand is regional. The trans-Pacific lane is benefiting from steady post-Lunar New Year demand recovery and improving shipping sentiment (the SONAR Ocean Booking Index climbed from 16,166 to 22,951 since late February). Carriers on this route have pricing power because volumes are ticking upward. In contrast, Asia-Europe demand remains soft, and carriers cannot sustain artificial rate increases when shippers have alternatives or can defer shipments. The implication for supply chain teams: your leverage depends on lane-specific demand, not geopolitical headline risk alone.
Implications for Operational Planning
For companies managing trans-Pacific inbound flows, the near-term calculus has shifted. Spot rates, while below Red Sea crisis peaks, are stubbornly elevated despite low seasonal demand. This creates margin pressure precisely when importers typically budget for lower transportation costs. Retailers and electronics manufacturers planning summer inventory builds face a choice: pay elevated rates now to secure space and lock in fuel surcharge levels, or gamble that peak season demand softens (reducing carrier pricing power) and rates moderate.
Analysts forecast the next major rate moves in June and July as peak season kicks into gear. However, the wildcard is consumer spending. If elevated energy costs—diesel at $5+/gallon, fuel surcharges baked into landed costs—dampen consumer demand, shippers may reduce volume commitments, suddenly flipping the market from tight to oversupplied. Carriers are hedging by cancelling GRIs and blanking sailings, suggesting they too sense demand uncertainty.
Looking Ahead: Prepare for Sustained Volatility
The Iran conflict has created a structural shift in cost assumptions. Unlike discrete disruptions (Red Sea attacks, trade war tariffs), sustained energy cost inflation is less dramatic but more persistent. Supply chain teams should model scenarios where bunker surcharges remain elevated through mid-year, peak season capacity is tighter than historical norms, and shipper volumes disappoint relative to carrier expectations. Building flexibility into sourcing, inventory, and logistics strategies—whether through alternative carriers, mode diversification, or demand signals to importers—will be essential to navigating this new environment.

Model impact on container spot rates, carrier profitability, and shipper landed costs across automotive, electronics, and consumer goods sectors.
Run this scenarioWhat if peak season demand fails to materialize in June-July?
Simulate a 15-20% reduction in typical peak season shipping volumes due to consumer cost sensitivity and war-related economic uncertainty. Model the impact on carrier utilization, rate stability, and inventory planning decisions for retailers and electronics importers relying on summer shipments.
Run this scenarioWhat if carriers expand blanked sailings to manage capacity?
Simulate increased blank sailings (reduce available capacity by 10-15%) on trans-Pacific routes if demand remains soft and carriers overestimate summer volumes. Model the impact on shipper transit time reliability, space availability, and premium charge exposure.
