SPLYLINE Supply Chain Intelligence

April 17, 2026

The week's defining story: a U.S. Navy blockade of Hormuz-bound vessels drove ocean freight rates off a six-week peak, pushed consumer sentiment to an all-time record low, and dominated earnings commentary from Prologis to FedEx. Meanwhile, diesel posted its first weekly decline after 12 consecutive weeks of increases. MODEX 2026 in Atlanta declared "physical AI" a production reality rather than a roadmap item. And Prologis delivered record leasing in a quarter that tells a very different story than the macro headlines suggest.

Section 122: Judges Signal Skepticism — No Ruling Yet

The April 10 oral arguments at the Court of International Trade produced no immediate ruling, but the signals from the bench were pointed. Three CIT judges — Mark Barnett, Claire Kelly, and Timothy Stanceu — pressed DOJ's Brett Shumate on the historical record underpinning the administration's claim that Section 122 grants broad emergency tariff authority. Legal analyst Ilya Somin observed that Shumate "erred on the historical record" of Nixon's 1971 tariff use and concluded the statute does not clearly grant the sweeping authority the administration claims. The 10% global surcharge remains in force pending the ruling. If the government loses, it eliminates the surcharge on approximately $1.2 trillion in imports — the same constitutional theory that already toppled IEEPA tariffs in February.

CAPE Portal: 56,000 Importers in Queue

CBP's CAPE refund portal for IEEPA duty refunds is targeting an April 20 launch with over 56,000 importers registered. Phase 1 is expected to cover approximately 82% of IEEPA duty payments — roughly $127 billion of the $166 billion total. Fox Rothschild's Lizbeth Levinson warned that refunds are not automatic: "You have to jump through hoops, even though customs should have taken it upon themselves to do automatic refunds." Companies that have not finalized claims documentation are running out of runway.

Trump's 50% China Threat and the Summit Clock

On April 12, Trump threatened an additional 50% tariff on China if Beijing were found to be supplying shoulder-fired anti-aircraft missiles to Iran. China's Foreign Ministry responded April 13: "Tariff wars have no winners," and Beijing warned of firm countermeasures. No formal rulemaking followed, but the threat adds a new variable to the May 14–15 Trump-Xi summit calculus. Analysts at the South China Morning Post described the summit as "compressed and disjointed given the Middle East war." The November 10 Busan tariff truce expiration remains the hard deadline that gives both sides a reason to deal.

USMCA: 40+ Senators Press USTR on Agricultural Access

More than 40 bipartisan U.S. senators wrote USTR Ambassador Jamieson Greer on April 16 ahead of the July 1 USMCA Joint Review, urging preservation of agricultural market access with Mexico and Canada. Greer also testified before House Appropriations this week defending a $95 million FY27 USTR budget — up $7 million from prior year. The Section 232 auto parts inclusions window closed April 14 at 11:59 PM ET.

Drewry WCI Falls 3% as Carriers Pre-Position for May

The Drewry World Container Index fell 3% to $2,246 per 40ft container on April 16, ending the six-week rally that had been driven by Hormuz-linked fuel spikes. Shanghai-to-LA slipped 3% to $2,810/FEU; Shanghai-to-NY fell 3% to $3,552; Shanghai-to-Rotterdam dropped 3% to $2,229; and Shanghai-to-Genoa fell 2% to $3,343. The one exception: Drewry's Intra-Asia Container Index surged 4% to $870/FEU as regional flows absorbed displaced capacity.

Carriers are not standing down on pricing. Nine blank sailings are scheduled on the Transpacific for week 17 to defend rate floors. Multiple lines have announced a Peak Season Surcharge of approximately $2,000/FEU effective May 1 — meaning the rate floor the market is currently watching may not be the one that governs Q2 procurement decisions. Over the next five weeks (weeks 17–21), Drewry's tracker shows 59 blank sailings scheduled out of 685 departures. Xeneta's Peter Sand noted that the rate spike since late February was most dramatic on lanes not transiting the Middle East, casting doubt on "tight capacity" as the primary explanation.

Hormuz: Blockade Holds, Diplomacy Stalls

The U.S. Navy blockade of vessels calling Iranian ports — which took effect April 13 — reduced Hormuz traffic to roughly eight tanker transits on Tuesday against a pre-war norm of approximately 130/day. CENTCOM chief Admiral Brad Cooper reported no ships breached the blockade in its first 24 hours. By Thursday, 10 vessels had been turned back. One Malta-flagged VLCC did enter for Iraqi Basra crude bound for Vietnam. Iran's IRGC is reportedly charging a $1/barrel toll through an alternative channel north of Larak Island.

China labeled the blockade "dangerous and irresponsible." Vice President Vance is expected to lead a second round of Islamabad-brokered negotiations. IEA Executive Director Fatih Birol stated this week that "resuming flows through the Strait of Hormuz remains the single most important variable in easing pressure on energy supplies, prices, and the global economy."

U.S. Port Volumes Hold — For Now

Port of Long Beach processed 774,935 TEU in March, down 5.2% year-over-year. Q1 total: 2.39 million TEU, down 5.7%. CEO Noel Hacegaba on April 15: "Despite these global pressures, the conflict has not yet reduced cargo volumes at the Port of Long Beach. What we're seeing instead is the impact of tariffs and timing." Port of Los Angeles ran parallel at 752,520 TEU in March, down 3% year-over-year, with Gene Seroka projecting April around 800,000 TEU. NRF/Hackett's Global Port Tracker now forecasts H1 2026 imports of 12.3 million TEU — down 1.8% year-over-year — suggesting the demand softening ahead will come from tariff-driven pull-forward exhaustion, not yet from disruption.

Consumer Sentiment Hits a 74-Year Low

The University of Michigan's preliminary April reading landed April 10 and has governed the entire week's macro narrative: consumer sentiment collapsed to 47.6 — the lowest reading in the survey's 74-year history, breaking the prior record of 50 set in June 2022. The index fell 10.7% month-over-month from 53.3. One-year inflation expectations surged from 3.8% to 4.8% — the largest single-month jump since April 2025. Five-to-ten year expectations ticked up to 3.4%.

Survey director Joanne Hsu noted that 98% of interviews were completed before the April 7 ceasefire announcement, meaning the data does not yet capture any post-ceasefire relief. "Demographic groups across age, income, and political party all posted setbacks," Hsu said. "Open-ended comments show that many consumers blame the Iran conflict for unfavorable changes to the economy." Personal finance assessments fell 11% — the worst since 2009. One-year business expectations plunged 20%.

For supply chain practitioners, the operational implication is straightforward: a consumer base this anxious about prices tends to compress discretionary purchasing faster than demand models built on 2025 conditions will predict. Retailers carrying inventory for peak season are pricing demand assumptions that this index no longer supports.

CPI Confirms the Pain at the Pump

March CPI released April 10: +0.9% month-over-month and +3.3% year-over-year — the highest annual rate since April 2024. Gasoline +21.2% month-over-month, the largest monthly increase since BLS first published the series. Energy overall: +10.9%. The Penn Wharton Budget Model updated April 15 pegs the effective U.S. tariff rate at 8.9% through February 2026, up from 2.3% in January 2025. JPMorgan estimates household tariff burden at $1,050–$1,300 annually.

Surcharges Become the New Price Floor

Multiple carrier and platform surcharges took effect this week. Amazon's 3.5% fuel and logistics surcharge on third-party FBA sellers went live April 17, adding to the 17-cent average FBA fee increase that took effect April 2. USPS's 8% temporary package surcharge launches April 26 through January 17, 2027. UPS and FedEx fuel surcharge tables reset higher. LyondellBasell pushed a 10-cent/lb contract hike on polyethylene — its second in two months — as PE prices have climbed 37% since late February and PP 38%, driven by Hormuz-linked force majeures.

The retail earnings calendar for this week was quiet on major announcements. The Census Bureau postponed March retail sales from April 16 to April 21, deferring the first hard demand signal on consumer response to Iran-war price increases.

Diesel Posts First Decline in 12 Weeks

The EIA's April 14 report showed national on-highway diesel at $5.608/gallon — down 3.4 cents week-over-week, the first weekly decline after 12 consecutive weeks of increases. The current price still sits $2.03 above April 2025. EIA's April Short-Term Energy Outlook projects diesel to peak above $5.80/gallon in April before averaging $4.80 for full-year 2026. IEA Executive Director Fatih Birol cautioned this week that global oil prices "don't yet reflect the severity of the supply crisis" — a signal that the diesel relief may be temporary.

The regional picture is uneven. The Midwest rose 7.8 cents to $5.382/gallon even as the national average fell. The West Coast declined double digits but remains above $6.00. California: $7.50/gallon.

Trucking: A Split Market with a Stress Signal

DAT's weekly data revealed a fractured spot market. Dry van spot rates jumped 18.6% week-over-week. Flatbed climbed 9.9% — its 15th consecutive weekly gain to the highest level since July 2022, driven by construction and reshoring-linked industrial freight. Reefer, however, collapsed 22.5% after four weeks of gains. The Logistics Managers Index shows a Transportation Prices reading of 89.4 against a sharply lower Transportation Capacity reading — a 50-point gap that analyst Dean Croke called "the loudest market stress signal since 2021." The March Cass Freight Index (released April 14) showed shipments down 4.5% year-over-year but up 3.0% month-over-month; expenditures up 4.2% year-over-year. TL Linehaul recorded its 15th consecutive year-over-year gain.

Rail: Solid Week 14, with a Merger Subplot

AAR's April 15 release for the week ending April 11 reported total U.S. traffic of 500,040 units, up 1.7% year-over-year. Carloads: 228,666, up 5.1%. Intermodal: 271,374 units, down 1.1%. Coal led commodity gainers at +13%; chemicals +7.5%; farm products +6.2%. Motor vehicles and parts fell 6.5% — a signal worth watching as Section 232 auto parts pressure builds.

On the UP-NS merger front, four shipper associations petitioned the STB on April 16 to unseal Schedule 5.8 of the merger agreement — the walk-away conditions currently restricted to outside counsel. The revised $85 billion application remains due April 30. BNSF CEO Katie Farmer told attendees at NEARS this week that a combined UP-NS would control half of all U.S. rail freight by revenue.

Air Freight Remains Elevated

Baltic Air Freight Index data through April 7 showed BAI00 up 25.2% over four weeks and up 15.8% year-over-year. The Shanghai outbound index (BAI80) climbed 41.8% month-over-month. Shippers priced off the Middle East routing disruption continue shifting volume to air on time-sensitive cargo, sustaining the premium above pre-war levels.

MODEX 2026 ran April 13–16 at Atlanta's Georgia World Congress Center, drawing over 1,060 exhibitors across 600,000+ square feet — 8% larger than the prior record set in 2024. MHI simultaneously announced MODEX West, debuting October 2028 in Las Vegas.

The dominant narrative of this year's show was the arrival of "physical AI" as a production-ready category rather than a demo concept. The MHI/Deloitte 2026 Annual Industry Report, released Monday, found 41% of respondents currently deploying AI — up from 30% in 2025 — with 48% calling AI's impact "significant or greater," a 25-point jump. MHI CEO John Paxton: "Supply chains can no longer be optimized at the edges. They must be rewired end-to-end."

Symbotic demonstrated its physical AI platform on the show floor; DA Davidson upgraded SYM to Buy with a $70 price target citing a "clear technology advantage in AI-enabled automation" observed at the booth. Exol — backed by a $7.5 billion SoftBank/Symbotic commitment — launched a fulfillment-as-a-service model with six physical AI sites and 6 million square feet of capacity planned. Locus Robotics unveiled Locus Array, a robots-to-goods autonomous fulfillment system, with DHL Supply Chain as early-access customer. CEO Rick Faulk: "For years, autonomous fulfillment has been more hype and promises than reality — until now." Dematic debuted its Command Center analytics platform and simultaneously announced a partnership with GreyOrange to deliver GreyOrange's GreyMatter orchestration engine across Dematic's installed base. Körber showcased NVIDIA Omniverse warehouse digital twins — the first announced collaboration between a major WMS vendor and NVIDIA's industrial simulation platform.

Gartner's enterprise SCM agentic AI software spend projection — $53 billion by 2030, up from under $2 billion in 2025 — framed how much of this investment is already priced in by the market. The practitioners walking the MODEX floor are no longer evaluating whether to automate. They are evaluating which system can deploy fastest against a labor pool that hasn't recovered and a freight cost structure that makes every unnecessary touch more expensive.

TSMC reported Q1 2026 revenue of NT$1.13 trillion (approximately $35.7 billion USD), up 35.1% year-over-year. CFO Wendell Huang: "We have strong conviction on the AI mega trend." The Arizona commitment now stands at $165 billion across six fabs plus advanced packaging. On process node yield: TSMC's 2nm is tracking approximately 65% yield; Samsung at approximately 55%; Intel 18A at 55–60%.

Rivian announced on April 14 a partnership with Redwood Materials to deploy 10 MWh of second-life battery storage at its Normal, Illinois assembly plant — an early data point in a broader trend Reuters reported this week: LG Energy Solution, Panasonic, and Samsung SDI are all converting idle EV battery lines to stationary storage for AI data centers, with LGES alone targeting 50 GWh/year by year-end. EV sales fell more than 25% after the September 30, 2025 expiration of the $7,500 federal credit; battery manufacturers are redirecting that capacity rather than idling it.

The labor constraint flagged in prior editions remains structurally unresolved. More than 500,000 manufacturing jobs are unfilled. U.S. labor at $25–$30/hour versus $6–$7 in China means reshoring economics require automation subsidy to close — which is exactly what MODEX exhibitors spent four days selling.

The week's largest M&A close was the completion of Echo Global Logistics' acquisition of ITS Logistics, creating a Thoma Bravo-backed full-service platform spanning parcel, LTL, and truckload with approximately $5.2 billion in combined scale — what FreightWaves called "a major consolidation tipping point" in the 3PL market. STG Logistics acquired Carrier Logistics Inc. on April 16 with a stated intention to build an AI-agentic platform for LTL terminal operations. TFI International's TA Dedicated acquired Triangle Warehouse the same day. Freight broker Fura announced its fifth acquisition, adding Barton Logistics to a roll-up strategy that has moved quickly since January.

On the executive side: FedEx CFO John Dietrich will step down June 1, coinciding with the FedEx Freight spinoff. Claude Russ, FedEx enterprise vice president of finance, will serve as interim CFO. Ryder named COO John Diez as next CEO, succeeding Robert Sanchez. Airforwarders Association Executive Director Brandon Fried announced year-end retirement after a long tenure. FreightWaves reported Brad Jacobs is stepping down as executive chairman of both XPO and RXO.

Prologis Q1 2026 results were the week's single clearest signal that industrial real estate has bottomed and is tightening. Core FFO per diluted share: $1.50 versus $1.42 in the prior-year period. Net earnings per diluted share: $1.05 versus $0.63. Record lease signings of 64 million square feet — the strongest quarter in company history for logistics leasing. Average occupancy: 95.3%. Cash same-store NOI: +8.8%. Net effective rent change: 31.9%.

CEO Dan Letter noted that seven weeks into the Hormuz conflict, "most customers are actively monitoring the situation and they are telling us 2026 business plans are unchanged." Managing Director Chris Caton projected U.S. net absorption on pace to approach 200 million square feet in 2026 against completions of approximately 190 million square feet — with U.S. vacancy flat at 7.5%, and the construction pipeline at just 1.7% of stock versus a 10-year average of 2.6%. That pipeline gap is what drives 2027 pricing power. Prologis raised full-year Core FFO guidance to $6.07–$6.23 per diluted share.

Industrial construction data from CBRE's Phoenix Q1 market report showed net absorption up 200% year-over-year to 4.9 million square feet with no one-million-square-foot blocks currently available. Interact Analysis projects U.S. warehouse additions bottomed at 585 in 2025 — down from 2,784 in 2022 — with only a modest uptick expected in 2026.

Proofpoint researchers published findings on April 16 documenting a new threat cluster targeting trucking carriers and freight brokers through load boards to physically divert cargo shipments. North American cargo theft reached $6.6 billion in 2025. Everstream's 2026 Annual Supply Chain Risk Report projects logistics cyberattacks will double this year — incidents are already up 61% year-over-year and 965% since 2021. IncRansom publicly claimed a ransomware attack on Rood Trucking this week with disclosures continuing.

GPS interference in the Hormuz region remains structurally elevated. Lloyd's List Intelligence tracked 1,735 GPS interference events affecting 655 vessels between the war's start and early March, with daily incidents doubling to 672/day. Windward's analysis this week characterized the post-ceasefire Hormuz regime as "a controlled system, not a recovery" — vessels transiting face active spoofing that falsely places them at airports, nuclear sites, and Iranian land territory, triggering insurance and compliance flags regardless of physical location. Demand for GPS alternatives, including celestial navigation and quantum magnetic navigation systems, is accelerating.

Weekly Dashboard — Week of April 13–17, 2026

Three strategic postures for supply chain leaders heading into the week ahead.

Treat the diesel dip as a data point, not a direction. The first weekly decline in 12 weeks looks like relief. The EIA is projecting a peak above $5.80 in April, IEA is warning that oil prices don't yet reflect supply severity, and the Hormuz blockade remains structurally intact. Any carrier or shipper adjusting fuel surcharge models on the basis of one week's 3-cent decline is building on sand. Diesel budgets for Q2 should remain calibrated to elevated levels until Hormuz traffic returns to something approaching pre-war norms — which no one is currently forecasting.

The CAPE portal is a cash flow event, not a compliance exercise. The April 20 launch with 56,000+ importers in queue is not a background IT project. For any company with meaningful IEEPA duty exposure in 2025, the refund mechanics now have a deadline and a process. The window to file is real; the friction is real; and waiting for automatic processing is, per trade counsel, not an option. Finance and trade compliance teams should be treating this like a receivables recovery, because that is what it is.

The Prologis data is a leading indicator, not a lagging one. Record leasing of 64 million square feet in Q1 — with CEO Dan Letter noting that customer 2026 business plans are largely unchanged despite seven weeks of conflict — is the clearest current-quarter signal that supply chain demand has not collapsed the way consumer sentiment suggests it might. Industrial tenants are locking space. That behavioral divergence between household confidence and corporate footprint decisions is the strategic gap practitioners should be watching. When those two data series converge, the direction of convergence will define the H2 story.

Strategic question for supply chain leaders: Consumer sentiment is at a 74-year low and industrial real estate leasing just hit an all-time record in the same quarter. Which signal is your organization building its second-half plan around?
