Smart Operators Watch Their Margins.
The Iran war is not mainly about bombs. It's about a chain reaction that hits your P&L before you see it coming. Oil, shipping insurance, air cargo, delivery times, inflation, consumer demand — that's where your margins get killed first.

The Iran war is not mainly about bombs. It's about a chain reaction that hits your P&L before you see it coming. Oil, shipping insurance, air cargo, delivery times, inflation, consumer demand — that's where your margins get killed first.
Signal 01
The Strait of Hormuz Is Still the Story
Ship transits through Hormuz dropped from roughly 130 per day in February to 6 in March. The IEA called this the largest supply disruption in the history of the global oil market — worse than the 1970s oil crises combined. Brent crude surged over 60% in March alone, the biggest monthly gain since records began.
Trump's 8 p.m. ET Tuesday deadline for Iran to reopen the strait is hours away. Iran rejected the latest ceasefire proposal and is demanding a permanent end to the war. Even Eurasia Group warns that the oil supply situation will double in severity by mid-April as strategic reserves run dry.
Signal
Energy costs are not just elevated — they are structurally disrupted with no clear timeline for normalization.
Why It Matters
Your shipping, supplier, packaging, and ad costs don't need to rise all at once to hurt you. Fuel alone starts the chain. Jet fuel has more than doubled. Diesel and bunker fuel are at record highs. Every link in your supply chain runs on energy.
⚡ Action
Recheck margins on every low-ticket product today. Especially bulky, fragile, low-AOV, or free-shipping offers. If your margin was 15% before and fuel adds 5-8% to fulfillment, you're underwater.
Don't price your business as if this is temporary. Even if a ceasefire happens tomorrow, Eurasia Group says it would take several months to repair damaged energy infrastructure and at least 2 months for tankers to resume — meaning 70+ empty oil tankers sitting off Singapore right now won't deliver barrels to Asia for 8+ weeks.
Amazon, USPS, FedEx & UPS Just Raised Your Costs
This is not hypothetical anymore. In the last 2 weeks, every major US carrier added war-related surcharges:
Amazon FBA: 3.5% fuel surcharge on all fulfillment fees starting April 17. Averages $0.17 extra per unit. Extends to Buy with Prime and MCF on May 2. No end date.
USPS: 8% surcharge on all competitive products (Priority Mail, Ground Advantage, Parcel Select) from April 26 through Jan 17, 2027. This is USPS's first-ever fuel surcharge in history.
FedEx & UPS: Fuel surcharges climbing weekly — reaching up to 26% of the total shipping cost in early March. Both added Middle East-specific surcharges.
Signal
Platform fulfillment costs are rising in real-time, across every carrier, with no end date announced for most surcharges.
Why It Matters
These surcharges stack on top of existing 2026 fee increases Amazon already announced in January. On thin margins, $0.17 per unit on FBA + 8% USPS increase + rising FedEx/UPS fuel rates = death by a thousand cuts. Sellers on forums are already saying: "Once you add a fee, it almost never goes away."
For marketplace sellers (eBay, Etsy), it's a double hit — fees are charged on total sale price including shipping, so higher shipping = higher platform fees too.
⚡ Action
Run your FBA fee calculator today with the 3.5% surcharge factored in. Amazon already updated Revenue Calculator and Profit Analytics. If any SKU goes negative, reprice or pause it before April 17.
If you offer free shipping, recalculate your threshold. A free shipping offer that worked at $29 might need to be $35 now. Or switch to flat-rate to absorb less risk.
Check if your 3PL has added surcharges too. If they haven't yet, ask what triggers one. Don't get surprised mid-month.
