On Friday, Brent crude touched $110 a barrel — the first time it has crossed that mark since May. By Monday it had eased to around $108–109, but nobody in the shipping business is relaxing. Gulf crude flows have collapsed to roughly 8.5 million barrels a day, and at least ten commercial vessels were hit or threatened in the Strait of Hormuz in a single week.
If you sell online, this is not a headline from someone else's industry. Diesel is the single biggest line item in moving a parcel from a factory to a customer, and carriers pass the cost to you through a line you may never have examined closely: the fuel surcharge. Here is what $110 oil actually does to an online business, the mechanics most sellers miss, and a practical playbook for protecting your margins.
Why oil jumped this week
The price spike is not one event — it is two wars feeding each other. In the Middle East, Houthi attacks on Saudi oil infrastructure and tankers in the Persian Gulf have gutted Gulf crude flows. Analytics firm Kpler reported flows down to about 8.5 million barrels a day on a seven-day average, from more than 20 million the previous week, with at least ten commercial vessels hit or threatened in one week. The US said its forces helped escort more than 100 million barrels through the Strait of Hormuz over the past week.
In Europe, Ukraine resumed strikes on Russian energy infrastructure — fires were reported at an oil export terminal and storage facility in St. Petersburg — while Russia and Ukraine traded attacks on energy targets.
Then politics added a twist. President Trump signed an executive order waiving key sanctions and tariffs under the Graham Act, a move that could open the door to more Russian fuel exports, alongside a diesel export deal with President Putin. Secretary of State Marco Rubio said the administration would take up to 60 days to assess the economic impact of the waiver. Brent has risen about 80% this year, and European diesel futures have more than doubled — so a weekend headline is not enough to bring relief.
"Mounting attacks on energy infrastructure and vessels are eroding hopes of a sustained recovery in oil flows," Jorge Leon, head of geopolitical analysis at Rystad Energy, told reporters this week. "The market is increasingly pricing in a longer disruption, with risks to prices tilted to the upside heading into the week."
How fuel becomes your shipping bill
This is the part many sellers misunderstand. When diesel rises, your carrier does not just raise the price of a parcel. It adjusts the fuel surcharge — a separate percentage tacked onto your base shipping rate, recalculated every week against published diesel indexes (in the US, the Energy Information Administration's diesel index). So oil goes up on Friday, and your shipping bill goes up days later, not months.
The surcharge is not small change. UPS and FedEx both imposed general rate increases of about 5.9% for 2026, but the real story is surcharges: fuel, delivery-area, and handling surcharges are now the primary drivers of total shipping cost, not base rates (Digital Commerce 360). The US Postal Service has added a temporary 8% package-shipping surcharge running through most of January 2027. The base rate you negotiated is increasingly a fraction of what you actually pay.
It does not stop at parcels. Fuel touches every step of the chain: ocean freight from Asian factories, road freight from ports to warehouses, plastic packaging (a petroleum product), and the last-mile delivery van. In the UAE, diesel hit Dh4.80 a litre this month — its highest level in years — and delivery firms are already warning customers (Gulf News).
Add them up and a seller is not facing one cost increase. It is four or five small ones arriving at different times, each easy to miss on its own.
The double tax most sellers never see
Here is the part that rarely gets said out loud: oil prices tax an online seller twice. The first tax is the cost side I just described — freight, surcharges, packaging. The second tax lands on your customers.
When fuel rises, everything rises: groceries, petrol, electricity. Consumers start watching their wallets. In September, US producer prices surged on record diesel and soaring tanker costs, and the effects were already spreading through farming, manufacturing, trucking and retail — which means consumers eventually feel it in higher everyday prices (Financial Express). A customer choosing between a full tank and your product is a customer who abandons the cart, buys the cheaper option, or waits for a sale.
Most sellers track only one of the two taxes. They notice shipping got expensive, raise prices a little, and then wonder why conversion dropped. The real math is: costs up and demand softer. That combination is what kills margins in a fuel spike — a seller with a 25% margin can find themselves near breakeven without a single dramatic event.
Why small sellers feel it first
Large retailers have tools you probably do not: fuel hedging, long-term carrier contracts, and enough volume to push back on surcharge tables. A third-party logistics provider (3PL) can use aggregate volume to negotiate base rates 10–40% below retail — one of the few genuine discounts available in shipping (Fulfill.com). Small sellers pay the published surcharge tables, in full, every week.
This is the uncomfortable asymmetry of a fuel spike. It does not punish everyone equally — it punishes whoever has the least bargaining power. A seller doing 30 orders a day and a seller doing 3,000 both pay the same diesel price, but only one of them has the volume to dilute it.
There is a second asymmetry worth knowing. Inventory bought before the spike is, in effect, a hedge: you sourced it when fuel was cheaper. The tradeoff is cash flow, and nobody should overstock on that basis alone — but if you are deciding between restocking now or later in a rising-fuel market, the calendar is costing you money.
The playbook: six moves that actually work
None of this requires a logistics degree. These are the responses that cross-border sellers and fulfillment experts keep coming back to when fuel spikes (sources: SourcinBox, Fulfill.com, Gulf News, Digital Commerce 360):
1. Audit your surcharges, not just your rates. Pull your last three carrier invoices and look at the surcharge lines separately. Many sellers discover surcharges have quietly added 15–25% on top of the base rate they thought they were paying.
2. Reconsider your free-shipping threshold. Gulf News reports sellers responding to fuel pressure by raising minimum-order values for free delivery and trimming express options — not by raising product prices first. A £35 free-shipping threshold that becomes £40 protects you more than a £1 price increase on every item, because it also lifts average order value.
3. Shrink the box. Carriers bill on dimensional weight — whichever is greater, actual or dimensional. Right-sizing packaging is the fastest cost cut in shipping, and with plastic packaging prices also tracking oil, using less of it pays twice.
4. Source closer when it makes sense. A product with a slightly higher unit cost from a regional supplier can end up cheaper overall once ocean freight, fuel surcharges and delay risk are priced in. Diversifying suppliers — not depending on one factory and one route — is the standard advice from cross-border operators (SourcinBox).
5. Compare carriers weekly, not yearly. Because surcharges update weekly, the cheapest carrier last month may not be the cheapest today. Even manual comparison for your top 20 routes catches drift that annual contract reviews miss.
6. Price deliberately, not reactively. Raising every price by the same percentage is the lazy response. Protect margins on low-ticket items where shipping is a large share of cost; hold prices on your bestsellers where conversion matters most.
What happens next: three scenarios
No one can forecast oil precisely, but a seller does not need precision — they need scenarios. The three that matter this quarter:
Scenario 1 — Escalation. If attacks on Gulf shipping continue or the Strait of Hormuz is disrupted, crude pushes toward or past $110, diesel follows, and surcharges stay elevated through the winter buying season — the worst possible timing for Q4 sellers.
Scenario 2 — The deal holds. Trump's sanctions waiver and the diesel arrangement with Russia bring more fuel into the market. Prices ease back toward $95–100. Surcharges drift down — but slowly, because surcharge indexes fall more reluctantly than they rise.
Scenario 3 — A grinding plateau. Oil hovers near current levels for months. This is quietly the hardest scenario: no crisis sharp enough to trigger emergency action, no relief clear enough to relax. Costs stay 10–20% above where your pricing was built, and margin erosion happens silently.
The honest base case for planning purposes is Scenario 3. Hope for 2, prepare for 1.
Frequently asked questions
How much do fuel surcharges actually add to shipping costs?
It varies by carrier and route, but surcharges of 15–25% on top of base rates are common in high-fuel periods — and they are the most volatile component of your shipping bill. Because they update weekly against diesel indexes, a spike in crude reaches your invoice within days (Fulfill.com).
Is dropshipping still profitable with oil at $110?
Yes, but the margin for error has shrunk. The sellers surviving the fuel spike focus on lightweight, small products, higher average order values, and stable logistics channels — the exact levers that reduce exposure to per-kilo freight and surcharges (SourcinBox). Heavy, low-margin products are the ones getting squeezed out.
Should I raise my prices or my free-shipping threshold?
Usually the threshold first. Raising the minimum order for free delivery protects margins while nudging customers to buy more — it converts a cost problem into a basket-size opportunity. Blanket price increases, especially on bestsellers, cost you conversion exactly when customers are price-sensitive (Gulf News).
When will shipping costs come back down?
Nobody can give a reliable date — it depends on oil prices, geopolitical tension and shipping capacity recovering (SourcinBox). Watch three signals: Brent falling back toward $95, the weekly diesel index turning down, and your carrier's surcharge table. When all three move together, relief is real. Plan for elevated costs through the winter and you will not be caught short.
Can a small seller negotiate better shipping rates?
Directly with a big carrier, rarely — volume is volume. But a 3PL aggregates thousands of small sellers' volume and negotiates 10–40% below retail base rates on their behalf, plus multi-carrier rate shopping and packaging optimization (Fulfill.com). For a seller doing dozens of orders a day, that is often the single biggest available saving.
The bottom line
Oil at $110 is not just a commodity story. For anyone who sells online, it is a margin story told in weekly installments: fuel surcharges that update before your pricing does, freight costs layered from factory to doorstep, and customers whose wallets are being squeezed by the same forces squeezing yours. The sellers who come through fuel spikes intact are the ones who read their invoices, protect their thresholds, shrink their boxes, and plan for the plateau.
