Hormuz Crisis Enters Fifth Week as Ship Transits Collapse 95%

The Strait of Hormuz crisis entered its fifth week as the defining supply chain event of 2026, with UNCTAD confirming a 95% collapse in daily ship transits. This week’s cascade: Trump restructured Section 232 metals tariffs on Liberation Day’s anniversary, the ISM Manufacturing PMI hit its strongest reading since August 2022 while input prices surged to a near-four-year high, diesel crossed $5.37/gallon nationally, and Amazon imposed a 3.5% FBA surcharge as fuel costs rippled through every freight mode. Container spot rates jumped 29–31% across all major east-west lanes. The fertilizer supply chain faces a “triple lock” — Hormuz, Russian export bans, and Chinese restrictions — threatening the Northern Hemisphere spring planting season. Against this backdrop, the Section 122 tariff legal challenge heads to oral arguments April 10, two massive Section 301 investigations advance toward comment deadlines, and the freight market continues its structural rebalancing from a three-year recession.

The Hormuz crisis is reshaping global trade in real time

The U.S.-Israel military operation against Iran that began February 28 has effectively sealed the Strait of Hormuz — the chokepoint through which 20% of the world’s oil and roughly 40,000 TEUs of containerized cargo transit weekly. UNCTAD’s April 1 rapid assessment confirmed daily transits plummeted from 129 ships per day in February to just 6 in March, a 95% drop. Over 120 container vessels remain trapped inside the Persian Gulf, with 37 attempting to exit. An estimated 20,000 seafarers are stranded, and the IMO is monitoring what it calls a humanitarian situation.

The crisis escalated further this week. On March 29, COSCO boxships were forced to turn back from the Strait after China’s negotiated “safe passage” arrangement with Iran collapsed — a significant blow given that Beijing had secured transit rights for Chinese, Russian, and Indian vessels just days earlier on March 26. On March 31, Tehran attacked and set ablaze a fully loaded crude oil tanker off Dubai. The Port of Salalah in Oman suspended operations after an Iranian drone strike but resumed March 31.

The IEA has described this as “the largest supply disruption in the history of the global oil market,” with global oil supply dropping more than 10%. Brent crude traded above $100/barrel through late March after spiking to $126 at its peak, and Dubai crude hit a record $166 on March 19. The IEA coordinated a release of 400 million barrels from strategic petroleum reserves — the biggest on record. CNBC reported oil analysts warning that Hormuz must reopen by mid-April or disruptions get “significantly worse,” with BCA Research estimating the world has lost 4.5–5 million barrels per day, a figure that could double.

Combined with the continuing Red Sea/Houthi disruption — Houthis resumed attacks on February 28 and launched their first missile strike on Israel on March 28–29 — both the Strait of Hormuz and Bab el-Mandeb are effectively closed, creating an unprecedented dual-chokepoint crisis. project44 reported 34,000+ route diversions in four weeks, with Saudi Arabia and Singapore emerging as key diversion destinations.

Why it matters: Every supply chain domain covered in this briefing traces back to Hormuz. Diesel prices, container rates, air cargo costs, fertilizer availability, manufacturing input costs, carrier surcharges, and consumer inflation expectations are all being reshaped by this single geopolitical event. The Panama Canal is absorbing some redirected traffic — operating at full 50-foot draft with 34–36 transits daily — but cannot offset the scale of disruption.

Container rates climb as carriers impose emergency surcharges

The Drewry World Container Index held steady at $2,287 per 40-foot container on April 2, following four consecutive weekly increases driven by the Hormuz crisis. Shanghai-to-New York stood at $3,434/FEU (+1% week-over-week), while Shanghai-to-Los Angeles eased slightly to $2,663/FEU (-1%). Asia-Europe rates showed the most dramatic moves: Shanghai-to-Genoa hit $3,474 and Asia-Europe spot rates surged 10% weekly to $2,883/FEU by month-end, per Container Management. The Freightos Baltic Index showed China/East Asia to North America West Coast at $2,183/FEU and to North Europe at $2,863/FEU.

Xeneta data published April 1–2 confirmed sharp rate increases across all major lanes: Far East to U.S. West Coast up 29% since end of February ($2,430/FEU), Far East to North Europe up 31%, and Far East to Mediterranean up 30%. Drewry expects spot rates to increase further, citing elevated fuel costs, Hormuz tensions, and carrier General Rate Increases taking effect.

Every major carrier has imposed emergency surcharges. CMA CGM set FAK rates of ~$3,500/FEU effective April 1 alongside a $2,000–$3,000/TEU conflict surcharge. Hapag-Lloyd implemented a $1,500/TEU war risk surcharge ($3,500 for reefers) plus a $1,000 GRI effective April 1 for Pakistan/India/Middle East to North America. Maersk levied $100–$600/container emergency bunker surcharges plus a $400/FEU global fuel surcharge. The FMC rejected carrier requests to waive the 30-day notice period for US-trade surcharges, forcing CMA CGM, Hapag-Lloyd, Maersk, and ZIM to delay some charges until early April.

Blank sailings moderated: Drewry’s tracker showed 38 cancellations across weeks 14–18 out of 706 scheduled departures (~5.4%), down from 7% in the prior period. The Gemini Cooperation (Maersk + Hapag-Lloyd) maintained the most reliable schedule with just a 1% cancellation rate. Meanwhile, the Premier Alliance (ONE, HMM, Yang Ming) plans to expand Pacific Southwest capacity by ~20% in April.

The NRF Global Port Tracker forecast March container imports at 1.89 million TEU (-12% year-over-year) and April at 2.05 million TEU (-7.1%). Hackett Associates founder Ben Hackett: “Following essentially flat container import volumes in 2025, we expect a decline during the first half of 2026 and likely longer.”

Liberation Day’s anniversary brings Section 232 overhaul and legal drama

On April 2, 2026 — the one-year anniversary of “Liberation Day” — President Trump signed a proclamation restructuring Section 232 tariffs on steel, aluminum, and copper. The new tiered system imposes a 50% flat tariff on articles made entirely of these metals, 25% on derivative articles substantially made from them, 15% through 2027 on metal-intensive industrial and electrical grid equipment, and 10% on products made abroad using American metals. Products with 15% or less metal content are exempted. This replaces a more complex derivative structure that had caused widespread compliance confusion.

The broader tariff landscape has changed dramatically since Liberation Day. The average effective U.S. tariff rate now sits at ~10–11% (Tax Foundation/Yale Budget Lab estimates), down from a peak of 21.5% in April 2025 — largely because the Supreme Court struck down IEEPA tariffs on February 20, 2026. Tariff policy has changed more than 50 times in the past year. The current regime rests on three pillars: Section 122 (10% temporary global), Section 232 (sector-specific), and Section 301 (country- and sector-specific).

The $166 billion IEEPA refund process advanced this week. On March 27, Judge Richard K. Eaton of the Court of International Trade expanded refund eligibility to include finally liquidated entries — removing a major hurdle for importers who hadn’t filed protests. CBP’s refund portal (CAPE system) is 63–85% complete and on track for mid-April deployment, with 26,664 importers registered covering 78% of affected entries by value (~$120 billion). Refunds will take up to 45 days after acceptance. The government has until May 4 to appeal.

The next critical date is April 10, when oral arguments begin at the CIT on two lawsuits challenging the Section 122 tariff — brought by 24 state attorneys general and two small businesses. The government’s response brief was due April 3. If the CIT strikes down Section 122 as it did IEEPA tariffs, it would eliminate the 10% global surcharge affecting ~$1.2 trillion in imports. Section 122 expires July 24 regardless.

USTR’s two massive Section 301 investigations — targeting structural excess manufacturing capacity across 16 economies and forced labor import enforcement across 60 economies — have comment deadlines of April 15 and public hearings in late April and early May. These are explicitly designed as replacement authority for invalidated IEEPA tariffs. The Section 232 auto parts quarterly inclusion window opened April 1–14 for requests to expand product coverage.

The US-China tariff truce remains intact: the reciprocal tariff suspension extends through November 10, 2026, with China’s retaliatory tariffs suspended through year-end. The overall U.S. tariff rate on Chinese goods sits at ~31%, down from a peak of 145%.

ISM manufacturing data shows expansion under duress

The ISM Manufacturing PMI for March came in at 52.7% on April 1 — up 0.3 points from February, beating consensus, and marking the third consecutive month of expansion and the strongest reading since August 2022. Production accelerated to 55.1%, and 13 of 18 industries reported growth.

But the alarm bells are in the sub-indices. The Prices index surged to 78.3% — up 7.8 points and the highest since June 2022 — reflecting a 19.3-point surge over two months, the steepest rise in nearly a decade. Supplier deliveries lengthened sharply to 58.9%, signaling supply chain tightness. New orders, while still expansionary at 53.5%, fell 2.3 points. Employment remained stubbornly in contraction. ISM Chair Susan Spence warned: “Our concern is that the demand indicators are going in the wrong direction.”

On the factory floor, U.S. Steel restarted Blast Furnace B at Granite City Works in Illinois on March 30, bringing 1,110 employees back to work after the furnace sat idle since November 2023. Only 12 operational steel blast furnaces remain in the U.S., down from 140 in the 1970s. Across the border, Canada’s Algoma Steel permanently shut Blast Furnace No. 7 and completed its transition to electric arc furnace steelmaking — driven by U.S. 50% steel tariffs that cost the company C$89.7 million in direct tariff costs in Q3. The closure ended 125 years of integrated steelmaking in Sault Ste. Marie and resulted in ~1,000 layoffs.

In semiconductors, a Taiwanese government filing on March 31 confirmed TSMC will produce 3-nanometer wafers at its second Japan fab (Kumamoto) by 2028, with 15,000 wafers/month capacity and an estimated ~$17 billion investment. This is a major upgrade from original plans focused on less-advanced nodes. TSMC’s $165 billion Arizona expansion continues, with Apple confirming it will purchase over 100 million advanced chips from TSMC Arizona in 2026. Intel’s newest Arizona fab entered high-volume manufacturing of 1.8nm chips in October 2025, backed by the government’s $8.9 billion equity stake in the company.

The EV battery sector is pivoting. GM and LG Energy Solution announced their Tennessee plant will retool from EV batteries to lithium-iron-phosphate cells for grid/energy storage and AI data center customers, with 700 laid-off workers returning by end of April. Honda completed a $2.85 billion acquisition of LG’s Ohio battery plant, which will produce batteries for Honda/Acura EVs.

Diesel shock cascades through every freight mode

National diesel prices hit $5.375/gallon in the week ending March 23 — up $1.31 in three weeks and the highest since late 2022. California diesel reached $6.87/gallon. FTR VP of Trucking Avery Vise called it the fastest two-week price surge in recorded history. Diesel powers more than 70% of U.S. freight, making this a direct and immediate inflationary input across all modes.

Trucking is responding. DAT weekly spot rates for dry van reached $2.34/mile (up 6¢ week-over-week), reefer hit $2.75/mile, and flatbed climbed to $2.80/mile. Critically, truck posts fell to the lowest Week 13 counts in over a decade across all equipment types — a clear signal of carriers pulling capacity as margins compress. The spot-contract rate gap has compressed from ~$0.39/mile a year ago to just $0.11/mile, and tender rejections are elevated at ~14%. C.H. Robinson forecasts 2026 dry van cost per mile up 8% year-over-year; Uber Freight’s Q1 update shows spot rates up 25% year-over-year.

Parcel carriers are passing costs through. Amazon announced a 3.5% fuel and logistics surcharge on FBA services effective April 17, averaging $0.17 per unit. Amazon stated this is “meaningfully lower than other major carriers.” USPS announced a temporary 8% price hike on package shipping services starting April 26. FedEx and UPS fuel surcharge tables continue escalating.

Air cargo rates are surging in parallel. The Baltic Air Freight Index rose 9.3% week-over-week and 10% year-over-year in the week ending March 30, with jet fuel prices up 100% year-over-year. The TAC Index warned rates “could yet rise considerably more… back toward peak season levels or beyond.”

Rail data from the AAR for the week ending March 28 showed total U.S. volume of 515,921 units, up 0.5% year-over-year. Intermodal volume rose 1.6% to 282,088 units, benefiting from trucking’s capacity crunch. J.B. Hunt CEO Shelley Simpson described demand as “slightly better than expected” at the Raymond James Conference. The proposed Union Pacific–Norfolk Southern $85 billion merger — which would create the first U.S. transcontinental railroad — is being revised for a April 30 STB refiling after the initial application was rejected in January.

Retailers recalibrate amid fuel costs and tariff uncertainty

Amazon dominated retail supply chain news this week. Beyond the FBA surcharge, Amazon ended stickerless commingling on March 31 (pushing operational responsibility upstream to sellers), expanded its dry van trailer fleet to 80,000 (up from 70,000 a year ago), and added 1,500 FedEx Office locations to its returns network — pushing total U.S. drop-off points past 10,000 and rekindling a relationship severed in 2019. Amazon also rolled out 1-hour and 3-hour delivery options across 90,000+ products in dense urban areas, with robots now handling ~40% of floor movements in major fulfillment hubs.

Consumer sentiment is deteriorating. The Conference Board Consumer Confidence Index ticked up to 91.8 in March, but the Expectations Index fell to 70.9 — well below the 80-point threshold associated with recession risk. The University of Michigan sentiment final reading dropped to 53.3, the year’s low, with one-year inflation expectations jumping to 3.8%. JP Morgan raised its 2026 recession probability to 35%.

Retailers are actively managing tariff exposure. Dollar Tree reported inventory down 7% year-over-year while sales grew 9%, and is opening a 1.25 million square foot distribution center near Phoenix. Mattel expects China to represent less than 40% of production by year-end (down from 50% in 2024). Academy Sports has cut China sourcing to 50% from 70% in 2019. Best Buy CFO Matthew Bilunas noted the “effective tariff rate is probably still in the mid-teens” with only small portions of assortment impacted.

Hasbro opened a 600,000 square foot distribution center in Midway, Georgia on March 19, in partnership with GXO Logistics — the company’s first fully self-developed U.S. warehouse, projecting $8 million in annual productivity savings. Walmart continues retrofitting 23 of 42 U.S. regional distribution centers with automation, with 35% of store-fulfilled orders delivered in under three hours in Q4.

Agentic AI goes mainstream across supply chain operations

The week’s technology narrative centers on one trend: agentic AI — autonomous AI systems that reason, decide, and act without human intervention — has crossed from pilot to production across the supply chain. Microsoft published its Supply Chain 2.0 strategy on March 24, targeting 100+ AI agents by year-end and equipping every employee with agentic support. C.H. Robinson revealed an AI engine powered by over 100 trillion proprietary data points. FedEx expects AI integrated into more than half of core operational workflows by 2028. Blue Yonder, Descartes (MacroPoint OpsForce), and AutoScheduler.AI all announced expanded AI agent deployments.

The most provocative launch came from Nuvocargo, which debuted Nuvo AI — described as the first AI-native truckload freight execution engine — deploying 12+ AI agents across 70%+ of touchpoints per load, from scheduling to rate negotiation to freight audit. CEO Deepak Chhugani: “We don’t sell software — we sell outcomes.”

Autonomous trucking is scaling rapidly. Aurora Innovation plans to deploy a second fleet of driverless International Motors trucks in Q2 with no human safety observers, after accumulating 250,000 driverless miles with zero collisions. Gatik became the first company to deploy fully driverless trucks at commercial scale in January, operating for Walmart with $600 million in contracted revenue. The SELF DRIVE Act of 2026 is advancing through Congress, and California DMV expects to complete autonomous trucking rulemaking by end of April.

Toyota Industries officially launched Toyota Automated Logistics on April 1, merging Vanderlande, viastore, and Bastian Solutions into a single global warehouse automation brand — a consolidation move that positions Toyota as a dominant force ahead of MODEX 2026 (April 13–16, Atlanta).

Major deals reshape the logistics landscape

The week’s most significant closed deal: Echo Global Logistics completed its acquisition of ITS Logistics on March 25, creating an AI-enabled 3PL with over $5 billion in annual revenue. The biggest pending deal: Thoma Bravo’s acquisition of WWEX Group (a $5 billion freight brokerage platform) to merge with portfolio company Auctane, announced March 3 with an expected Q2 close — creating one of the largest and most diversified logistics technology platforms.

In maritime M&A, Hapag-Lloyd’s $4.2 billion acquisition of ZIM (announced February 16) continues through regulatory review, with closure expected late 2026. It will create the world’s fifth-largest carrier with 3+ million TEU capacity. ONE signed for a 30% stake in Hutchison’s Laem Chabang Terminal in Thailand, reflecting carriers’ push toward vertical integration.

Prologis and GIC formed a $1.6 billion joint venture (announced March 19) to develop build-to-suit logistics facilities across major U.S. markets, starting with 4.1 million square feet. Einride raised $113 million in an oversubscribed PIPE ahead of its NYSE SPAC listing at a $1.35 billion pre-money valuation. Cart.com raised $180 million from Springcoast Partners to expand its fulfillment platform.

Key executive moves: Toyota Automated Logistics named three regional CEOs — Aaron M. Jones (Americas), Thomas Hibinger (EMEA/APAC), and Hitoshi Matsuoka (Central). ANA installed Juichi Hirasawa as President and CEO on April 1. Allcargo Logistics made three senior hires. Honeywell announced it may spin off its warehouse and workflow solutions divisions (~$2 billion combined revenue) as part of its planned separation into three companies by H2 2026.

The fertilizer triple-lock threatens food supply chains

A slow-moving crisis deserves urgent attention. Three simultaneous supply shocks have converged on the global fertilizer market during the Northern Hemisphere’s critical spring planting window. The Strait of Hormuz has seen zero approved fertilizer transits in 24 days — Gulf countries account for ~49% of global urea exports and ~30% of ammonia exports (American Farm Bureau Federation testimony, March 26). Russia suspended ammonium nitrate exports until after April 21, removing 3–4 million tonnes annually. China banned exports of nitrogen-potassium blends and phosphate fertilizers through August 2026.

The result: urea prices surged from ~$350/ton in late 2025 to over $800/ton by late March — more than doubling. Helios AI forecasts global food prices could rise 12–18% above pre-crisis levels by end of 2026. Oxford Economics raised its fertilizer price forecast by 20% for Q2. Wolfe Research estimates the disruption could add ~2 percentage points to U.S. food-at-home inflation. The Trump administration implemented a Jones Act waiver to improve domestic fertilizer transport between U.S. ports, and the AFBF has recommended using the U.S. Navy for safe fertilizer transit through Hormuz.

Cybersecurity threats and labor stability round out the risk picture

On the positive side, the ILA ratified its six-year master contract with USMX on February 25 with near-unanimous approval — including a 62% pay raise over six years and a technology implementation framework. There is no East/Gulf Coast port strike risk through 2030–2031. However, the ILA lost two court decisions related to terminal automation and faces damages for illegal strike action.

Cybersecurity remains elevated. Everstream Analytics’ 2026 Annual Risk Report projected cyberattacks on logistics to double in 2026, with incidents up 965% since 2021 and 61% in 2025 alone. State-sponsored actors from Russia, China, and Iran are leading coordinated campaigns against maritime infrastructure. Russian GPS jamming and spoofing in the Baltic Sea — an economic zone handling 15% of global cargo shipping — continues to intensify. No major confirmed cyber incident hit the logistics sector this specific week, but the threat environment amid the Iran war remains acute.

Conclusion: What to watch in the week ahead

The supply chain world is operating in crisis mode, with the Hormuz closure acting as a force multiplier across every domain. Five developments in the coming days will shape the next phase. April 10 oral arguments on the Section 122 tariff challenge could eliminate the 10% global surcharge on $1.2 trillion in imports — the most consequential trade law event since the IEEPA ruling. Mid-April should see CBP’s CAPE refund portal go live, beginning the flow of $166 billion back to importers. Oil analysts warn that if Hormuz stays closed past mid-April, supply disruptions could double — making any diplomatic or military resolution the single most important variable for global logistics costs. The ISM’s stagflationary signal — strong production alongside surging prices and contracting employment — suggests the manufacturing recovery is fragile. And with MODEX 2026 opening April 13 in Atlanta, the warehouse automation and robotics sector will showcase technology that may define how supply chains adapt to a world of persistent disruption. The common thread: resilience is no longer a strategic nice-to-have. It is the operating requirement.
