Commercial shipping volumes through the Bab el-Mandeb strait have plummeted as regional conflict forces tankers and cargo vessels to divert around the Cape of Good Hope, adding significant transit time and fuel costs to global energy deliveries.
This disruption in Middle Eastern energy corridors is coinciding with the implementation and proposal of aggressive tariff frameworks by the Trump administration, creating a compounding cost pressure on global supply chains. Even as tariffs are designed to shift trade balances and incentivize domestic production, the simultaneous rise in energy logistics costs is inflating the baseline price of the remarkably goods those tariffs target.
Energy Logistics and Transit Costs
The volatility in the Red Sea and the Gulf of Oman has forced a reconfiguration of oil and liquefied natural gas (LNG) routes. Shipping firms have reported a sharp increase in freight rates and insurance premiums for vessels traversing high-risk zones. For tankers diverting around Africa, the journey can add up to 10 to 14 days of travel, increasing the consumption of bunker fuel and reducing the frequency of deliveries.
These delays create a “floating inventory” effect, where significant volumes of energy are trapped in transit, tightening immediate spot market availability. For industrial consumers, this manifests as higher energy input costs, which are then layered onto the costs of raw materials already subject to trade levies.
The Tariff Mechanism
The Trump administration’s trade strategy centers on the application of broad tariffs on imports, particularly from China and several European allies, to reduce trade deficits and counter perceived unfair trade practices. These tariffs function as a tax on imported goods, which importers typically pass on to consumers or absorb through reduced profit margins.
When these tariffs are applied to intermediate goods—such as steel, aluminum, or electronic components—the cost of domestic manufacturing rises. When those manufacturers must also pay higher energy prices due to Middle Eastern supply disruptions, the cumulative effect is a “double squeeze.” The cost of producing a good increases due to energy prices, while the cost of importing the components to build that good increases due to tariffs.
Compounding Economic Pressures
Economic data indicates that energy is a primary input for nearly every sector of the global economy. In the chemicals and plastics industries, for example, feedstock prices are directly tied to oil and gas availability. The disruption of these supplies from the Middle East raises the cost of production at the source.
Simultaneously, tariffs on finished chemical products or the machinery used to produce them increase the capital expenditure required for firms to maintain operations. This intersection prevents companies from using energy efficiency gains to offset the costs of tariffs, as the volatility of the energy supply chain cancels out potential savings.
Institutional analysts have noted that while tariffs are intended to decouple specific economies, the global nature of energy markets means that instability in the Middle East affects all trading partners regardless of their tariff status. A spike in Brent crude or LNG prices acts as a universal tax on global trade, amplifying the inflationary pressure already present from trade barriers.
Institutional Responses
The International Monetary Fund and the World Trade Organization have previously warned that “trade fragmentation”—the splitting of global trade into competing blocs—increases vulnerability to external shocks. The current overlap of geopolitical conflict in energy-rich regions and a shift toward protectionist trade policies serves as a practical example of this vulnerability.
Industry groups in the manufacturing sector have signaled that the combination of higher freight costs and tariff duties is making long-term pricing contracts difficult to maintain. Many firms are now shifting toward shorter-term pricing models to account for the rapid fluctuations in both energy costs and trade policy.
The U.S. Department of Commerce continues to monitor the impact of these overlapping pressures on domestic price stability, while the administration maintains that the long-term benefits of tariffs outweigh the short-term transitional costs.
The next scheduled review of tariff exemptions for critical industrial components is pending a formal assessment of supply chain stability in the energy sector.
