Fragile Cease-Fire Arrives with Conditions, One of Which Being the Reopening of the Strait of Hormuz
A tentative two-week ceasefire between the U.S., Iran, and Israel is giving global markets a temporary reason to exhale, but it is not the same thing as long-term stability. Reporting on April 8 showed that the agreement was reached after a late diplomatic push and is tied to Iran allowing the reopening of the Strait of Hormuz, one of the world’s most important oil transit routes. The pause appears to have reduced the immediate risk of a broader escalation, but it is widely being described as fragile, with key military and political questions still unresolved.
That matters well beyond the Middle East. The Strait of Hormuz is central to global energy flows, and any threat to shipping through the corridor can ripple quickly into fuel markets, freight pricing, and international supply chain planning. Even before the ceasefire announcement, the conflict had already helped drive a sharp rise in oil prices and raised concerns about wider disruption to shipping networks. Reuters reported that crude prices pulled back after the truce news, showing how closely markets are tracking the risk of prolonged instability in the region.
For shippers, the most important lesson is that even a ceasefire can leave major uncertainty in place. The current pause does not settle questions around Iran’s nuclear program, regional proxy conflict, or the long-term security of shipping through Hormuz. It also does not fully stop fighting across the region. Reuters and AP both reported that the ceasefire does not necessarily extend cleanly to Lebanon and that attacks continued in some areas even as the broader truce took hold.
That makes this less of an ending and more of a reset point. Freight markets may see some near-term relief if energy prices stabilize and vessel traffic normalizes, but planners should not assume the risk has disappeared. The broader supply chain impact of the conflict has already shown how quickly geopolitical tension can affect fuel costs, ocean rates, and international shipping confidence.
The practical takeaway is simple: treat the ceasefire as a welcome development, but not as a signal to stop watching the region. For logistics teams, this is still a moment for close fuel monitoring, flexible planning, and active communication with carriers and partners. As the last several weeks have shown, disruption in one strategic corridor can quickly reach far beyond its immediate geography.

Diesel Prices Slow, but Cali is Still Struggling
After several weeks of steep diesel increases, the end of March finally brought a little relief to the broader freight market. Supply Chain Dive reported that the U.S. average on-highway diesel price increased only 2.6 cents in the latest weekly reading, a noticeable slowdown from the prior week’s 30-cent jump. That smaller increase suggests the national diesel surge may be losing momentum, even though prices remain historically high.
The problem is that national averages do not tell the whole story. According to the article, three of the seven tracked regions actually posted week-over-week declines, showing that some parts of the country are beginning to stabilize. But California continued to move sharply higher, with its average diesel price rising by about 35 cents to nearly $7.22 per gallon.
That matters because California is too important to freight markets to dismiss as a regional exception. The state plays a major role in port activity, warehouse distribution, agricultural shipping, and long-haul trucking. When fuel prices in California remain far above the national average, carriers operating in those lanes face higher operating costs, and those pressures can filter through to shippers in the form of higher transportation expenses and fuel surcharges.
The article also points out that diesel’s dramatic March run-up followed geopolitical disruption tied to the conflict involving the U.S., Israel, and Iran, which helped push fuel markets higher nationwide. Even with some late-March relief, diesel prices are still sitting at levels not seen in years. That means this is not a return to normal so much as a pause in a still-expensive fuel environment.
For shippers, the lesson is straightforward: keep watching fuel trends, but do not rely too heavily on the national number alone. A softer U.S. average can hide serious regional volatility, and California is a good example of how one major freight market can continue to face significant cost pressure even while broader conditions improve.

Tight Trucking Capacity is Pushing Shippers Toward Intermodal
As pressure builds across the trucking market, more shippers are taking a fresh look at intermodal. Supply Chain Dive reported that current market conditions are creating an opening for companies to secure lower intermodal pricing before it begins to catch up with rising truckload costs. According to Uber Freight’s Q1 Market Update, truckload spot rates are up 25% year over year, while intermodal capacity remains much more available.
That gap matters. Uber Freight told Supply Chain Dive that intermodal rates typically lag over-the-road pricing by 6 to 12 months, which means intermodal has not yet fully reflected the rate pressure building in trucking. For shippers, that creates a short-term opportunity to lock in more favorable pricing before rail costs start moving higher. Uber Freight expects intermodal pricing to increase 3% to 5% by the end of the year.
The shift is happening against a broader backdrop of tighter trucking conditions. The article notes that both LTL and full truckload markets are feeling the impact of ongoing federal enforcement related to nondomiciled commercial driver’s licenses and CDL mills, which is squeezing capacity across the over-the-road market. At the same time, higher diesel prices are adding more pressure, especially on smaller carriers and owner-operators that have less protection from fuel volatility.
Supply Chain Dive also pointed to signs that shippers are increasingly considering intermodal for freight in the 550- to 1,500-mile range, where the service can offer a practical balance of cost savings and network efficiency. C.H. Robinson noted in its March market update that while it may still be too early to tell whether this is a lasting mode shift or a shorter-term reaction to disruption, the trend is worth watching closely. Outbound intermodal rates on the West Coast have largely stabilized, and rail spot rates are expected to remain steady through the second quarter.
The broader lesson is that intermodal should no longer be viewed only as a backup plan. In a market where trucking costs are climbing and capacity is getting tighter, intermodal can serve as a strategic part of transportation planning, especially for shippers looking to control costs without giving up network flexibility. Companies that act before pricing adjusts may be in a better position to build both savings and resilience into their freight strategy.

Oil Prices Stay Elevated as Deadline Pressure Keeps Energy Markets on Edge
Oil prices remained high and volatile as markets watched President Trump’s deadline for Iran to reopen the Strait of Hormuz. While day-to-day price swings continued, Reuters reported that Brent crude was trading around $109 per barrel and West Texas Intermediate near $112 per barrel on April 6, following a sharp rally earlier in the month. The market’s concern is not simply headline risk. It is the possibility that disruption in and around the Strait of Hormuz could continue to interfere with global oil flows and keep energy markets tight.
That matters because the Strait of Hormuz is one of the world’s most important energy corridors. When traffic through the strait is threatened or restricted, oil markets react quickly because the region plays an outsized role in global crude supply. Reuters reported that the ongoing conflict and uncertainty around Hormuz helped drive a record March surge in oil prices, with countries differently exposed depending on whether they can bypass the strait through alternative export routes.
For transportation and logistics, higher crude prices are rarely just a commodities story. They feed directly into diesel costs, fuel surcharges, carrier operating expenses, and overall freight pricing. Even if trucking capacity or shipping demand does not shift overnight, sustained energy volatility can raise the cost of moving freight across modes and regions. That is especially important for shippers trying to manage budgets in a market already dealing with uneven capacity and fragile cost stability.
Another key takeaway is that markets are now being driven more by geopolitical risk than by traditional supply-and-demand signals alone. Reuters noted that refiners are already seeking alternative crude sources, OPEC+ has announced a modest production increase for May, and analysts are closely watching whether diplomacy can reduce the risk of further disruption. But for now, the market still appears to be pricing in significant uncertainty.
For shippers, the practical lesson is to keep a close eye on fuel exposure. Even if oil prices do not surge much higher from here, the current environment can keep diesel prices elevated and transportation costs under pressure. That makes fuel monitoring, surcharge planning, and mode flexibility more important than usual as companies prepare for what could remain a volatile energy and freight landscape.

Amazon’s New Seller Surcharge Shows How Fuel Pressure Keeps Spreading Through the Supply Chain
Amazon is adding a temporary 3.5% fuel and logistics-related surcharge to third-party sellers that use its fulfillment network, a move that highlights how higher fuel costs continue to ripple beyond carriers and into the broader retail supply chain. According to reporting from The Wall Street Journal and corroborating coverage from the Associated Press and others, the surcharge will begin on April 17, 2026 for sellers using Fulfillment by Amazon in the U.S. and Canada. It will also extend to Buy with Prime and Multi-Channel Fulfillment starting May 2.
Amazon says the surcharge is a response to rising fuel and logistics costs tied to the current energy environment. The company said it had been absorbing those added costs but now needs to recover part of them. The fee is calculated on fulfillment fees rather than sale prices, and Amazon said it will average around $0.17 per unit for U.S. FBA orders.
That may sound small at the unit level, but for sellers operating on thin margins, even a modest fulfillment increase can matter. Businesses selling low-margin goods, high-volume items, or products with tight pricing competition may have little room to absorb another cost increase. Some sellers will likely try to hold the line to protect conversion and market share, while others may pass the added cost along to customers. Either way, the surcharge adds more strain to an environment already shaped by elevated transportation and operating expenses.
This is also significant because it shows how fuel volatility is moving through the supply chain in layers. Carriers have long used fuel surcharges, but now similar logic is reaching large fulfillment ecosystems and e-commerce service models. Amazon pointed out that other major providers such as FedEx, UPS, and USPS have also implemented or increased fuel-related surcharges, reinforcing that this is not an isolated pricing decision but part of a broader logistics cost environment.
For shippers, retailers, and e-commerce brands, the practical takeaway is simple: fuel costs are no longer just a transportation line item. They can now affect fulfillment fees, marketplace economics, and end-customer pricing decisions. Even companies that do not move freight directly may still feel the impact as logistics costs work their way deeper into retail and distribution models.
