The Port of LA Says Summer Is Fine. Walmart Suppliers Should Be Thinking About Fall.

The Port of Los Angeles processed 752,520 TEUs in March, down 3% year over year, according to port data cited during a media briefing Monday by Executive Director Gene Seroka. He was quick to explain the decline: importers frontloaded cargo ahead of tariff announcements a year ago, creating a difficult comparison. Strip that out and the picture is solid. April volumes are tracking toward 800,000 TEUs per the port’s Port Optimizer data. Retailers are replenishing spring and summer goods on schedule. Seroka described the Iran war’s impact on the port as “a concern, but it’s not a worry.”

He also said it will take months to untangle the supply chain web, even if a resolution is reached. That sentence is doing more work than the reassurance.

The Ceasefire Did Not Open the Strait. Neither Did the Talks.

The Strait of Hormuz has been effectively closed since late February, when U.S. and Israeli strikes on Iran triggered what has become one of the largest disruptions to global energy and shipping flows in decades. More than 40 days into the conflict, as Seroka confirmed Monday, daily vessel crossings through the strait remain a fraction of pre-war levels. A two-week ceasefire announced last week initially raised hopes. Xeneta, the ocean freight analytics firm, said in an April 8 statement reported by Supply Chain Dive that the ceasefire would not restore container shipping operations through the Strait. Vespucci Maritime CEO Lars Jensen said carriers would likely exit the Persian Gulf during the ceasefire window but remain cautious about re-entering while uncertainty persists. Over the weekend, U.S.-Iran talks in Pakistan stalled, according to Supply Chain Dive.

The transpacific lane itself is not physically disrupted. Cargo moving from Asia to the U.S. West Coast does not pass through the Strait of Hormuz. What the conflict is doing to that lane is more indirect and more durable: fuel costs are up, vessel capacity that might otherwise be available on transpacific routes is tied up in rerouting around the Cape of Good Hope on other lanes, and the rate environment has shifted. Transpacific rates to the U.S. West Coast have risen approximately 40% since the start of the conflict to more than $2,400 per FEU, per the Freightos Baltic Index as reported by Supply Chain Dive on April 8. Those rates now sit approximately 8% above year-ago levels, reversing what had been a significant year-on-year deficit heading into the conflict.

Summer Replenishment Is Already Moving. That Is Not the Question.

The Port LA data and Seroka’s characterization of the current environment are accurate and relevant. Retailers moving spring and summer merchandise through the transpacific corridor right now are doing so in a functioning market. The Walmart Q4 fiscal year 2026 earnings presentation noted tariff and trade policies as material uncertainties, and the company’s buyers have been navigating that environment alongside their suppliers for months. The summer replenishment cycle currently moving through the Port of LA reflects planning decisions made earlier this year under those conditions.

The question is what happens to the planning decisions being made right now for Q3 and Q4 imports. Lead times for fall and holiday merchandise from Asian manufacturers run four to six months. Suppliers placing orders and booking freight for October, November, and December deliveries are making those decisions in April and May. They are doing so in a freight market where rates have risen 40% since February, where fuel surcharges are stacked on top of base rates, where the Hormuz disruption has no confirmed resolution timeline, and where Seroka himself said untangling the web will take months regardless of outcome.

That is a materially different cost and lead-time environment than the one those suppliers were modeling in their Q4 planning assumptions six months ago.

The Cost Is Already in the System. The Timing Risk Is Still Ahead.

The Freightos Baltic Index data reported by Supply Chain Dive shows transpacific rates have climbed steadily since late February. As fuel surcharges continue passing through the market, suppliers should expect upward pressure on landed costs to persist rather than ease. Rates that were running more than 50% below prior-year levels before the conflict have now reversed to sit above year-ago comparisons. For Walmart suppliers, a prolonged conflict that eventually suppresses global consumption and softens container demand later in the year does not resolve the problem. It changes it.

The more immediate issue is cost absorption. Transpacific rates up 40% on a lane that was already running below year-ago levels does not simply add to freight invoices. It changes the economics of which items can be profitably imported at current Walmart cost structures. Walmart has been consistent in protecting its Every Day Low Price positioning, and its Q4 FY2026 earnings call confirmed the company’s focus on rolling back prices across grocery and general merchandise categories. Suppliers whose landed cost calculations were built on pre-conflict freight assumptions are now carrying a gap that needs to close somewhere. Cost negotiation, packaging reduction, order consolidation, and sourcing adjustments are all levers, but all of them take time to execute and most of them require Walmart’s buyers to be part of the conversation.

The Window to Act Is This Planning Cycle, Not the Next One

For Walmart’s import-dependent suppliers, the actionable question is not whether the Hormuz conflict will affect fall shipping. It already has, through rates, fuel costs, and the forward uncertainty that carriers and shippers are both pricing in. The question is whether suppliers are treating that as a current planning problem or as something to revisit once the situation clarifies.

Seroka’s framing is appropriate for a port operator managing current throughput: concern but not worry. It is not the right frame for a supplier modeling the cost and lead-time assumptions behind a Q4 line review or a JBP conversation scheduled for May or June. Walmart’s Q4 earnings presentation cited tariff and trade policies alongside geopolitical conditions as factors that could materially affect results. Suppliers who bring updated freight cost modeling and contingency lead-time scenarios to those conversations are better positioned than suppliers who are waiting for the situation to resolve before adjusting their numbers.

The Port of LA’s April volumes will come in strong. Summer goods are moving. The transpacific is functioning. None of that changes what it costs to move a container today versus what it cost in January, or what Seroka said about how long the untangling will take. Both things are true. Only one of them requires action right now.
