Editor’s note: This op-ed for Bus & Motorcoach News is written by UMA Member Peter Shelbo, co-owner of BUSBooks, a specialty accounting firm dedicated to the motorcoach industry.
Before joining a CPA firm serving the motorcoach industry, I spent 30 years as a motorcoach operator. Like many of you, I watched fuel prices swing wildly over the years — sometimes slowly, and sometimes overnight.
When fuel moves quickly, margins can disappear just as fast. The cycle has returned.
30-second takeaway
- Middle East tensions are beginning to influence global oil markets.
- Diesel prices can move quickly when geopolitical risks increase.
- Some markets are already approaching $7 diesel, and $10 fuel is not impossible in a severe supply disruption.
- Operators already facing rising insurance costs could see margins squeezed further.
- Fuel surcharges are widely used across transportation industries.
- Motorcoach operators should consider implementing or updating surcharge policies before fuel spikes affect profitability.
The industry has rebuilt

Over the past few years, the motorcoach industry has done something remarkable.
It rebuilt itself.
When COVID shut down group travel, coaches across the country were parked. Charter work disappeared overnight. Companies that had spent decades building their businesses suddenly found themselves fighting simply to survive.
But this industry has always been resilient.
Operators tightened expenses, protected their fleets, kept key employees, and waited for travel to return.
And return it did.
Today, operators are experiencing one of the strongest demand environments the industry has seen in years. Schools are traveling again. Domestic tour groups are back. Sports teams and corporate groups have returned to the road. The international tourism market has collapsed, but that is another story.
For many companies, the industry has entered a welcome period of renewed prosperity.
But experienced operators also know something else about this business.
Good times can stop quickly due to forces outside the industry’s control – the effect of a sudden surge in fuel prices.
Why the Iran conflict matters
The recent escalation of tensions in the Middle East — particularly involving Iran — has introduced uncertainty into global oil markets.
Oil is traded globally. Even though the United States produces a substantial portion of its own energy, prices still respond quickly to geopolitical risk. When instability appears in major oil-producing regions, markets react almost immediately. Even the possibility of disruptions to production or shipping routes can push prices higher.
For diesel-dependent industries like motorcoach transportation, those reactions show up quickly at the pump.
Unlike labor costs, insurance premiums, or maintenance expenses, fuel prices can change dramatically in a brief period. And when they do, the impact on operating margins is immediate.
Fuel surcharges are nothing new
Fortunately, the transportation industry has dealt with this before.
Fuel surcharges have been used across trucking, airlines, and passenger transportation for more than two decades. Whenever fuel prices spike—as they did in the mid-2000s, during the 2008 oil surge, and again during the diesel increases in 2022—transportation providers rely on surcharges to manage rapidly rising fuel costs.
The reason is simple.
Trips and contracts are often priced months in advance. Fuel prices can move dramatically in a matter of weeks or even days.
Fuel surcharges help bridge that gap by allowing operators to maintain their base pricing while adjusting for extraordinary fuel increases transparently and predictably.
Most customers already understand the concept because they see it regularly on airline tickets and freight shipments.
Operators are already feeling cost pressure
Fuel volatility is arriving at a time when motorcoach operators already face rising costs.
Insurance premiums across the industry have been climbing steadily. Liability coverage has become more expensive, and many operators have experienced significant increases in annual premiums.
Insurance increases are difficult, but they usually happen gradually.
Fuel costs behave very differently. They can rise quickly—and when they do, they move far faster than insurance costs.
A typical coach traveling about 100,000 miles per year may consume more than 10,000 gallons of diesel annually. A $1 increase in diesel prices adds roughly $10,000 in annual fuel cost for that single coach. A $2 increase adds $20,000 in annual costs per coach, and a fleet of 20 coaches will drain $400,000 from the bottom line.
While insurance increases are squeezing margins, fuel increases can outpace those pressures overnight.
How high could diesel go?
Operators should also consider how high diesel prices could climb.
In parts of the country, diesel prices are already reaching levels that would have seemed extreme a few years ago. In California, diesel is already approaching $7 per gallon in certain markets.
If global oil markets tighten further, prices could climb much higher. In a severe supply disruption, $10 diesel at the pump is not a dream.
For companies running multiple coaches every day, that kind of increase cannot simply be absorbed.
Fuel surcharge example

Many operators ask what a simple surcharge structure might look like. The graphic above is a straightforward example commonly used in transportation:
Again, this is a simple example. Many companies reference the U.S. Energy Information Administration weekly diesel price index when applying fuel surcharges.
Using a public index helps keep the process transparent and easy to explain to customers.
Motorcoach operators have always been problem solvers.
This industry has navigated recessions, fuel cycles, regulatory changes, and even a global shutdown. The recovery we are seeing today is proof of that resilience.
But protecting that recovery requires staying ahead of potential risks. If diesel prices continue rising quickly, operators who implement fuel surcharges early will be in a far stronger position than those who wait.
