Does Gas Go Up During War? The Surprising Truth

You see the headlines, feel the tension, and your first thought is probably about your wallet. Does gas go up during war? The short, frustrating answer is: usually, but not always, and definitely not in the simple way most news reports make it seem. I’ve been tracking energy markets for over a decade, and the knee-jerk reaction to blame every price hike on a new conflict misses a much more intricate story. Yes, the 2022 Russian invasion of Ukraine sent prices soaring past $5 a gallon in the US. But the 2003 Iraq War saw prices actually fall after the initial invasion. So what gives?

The Direct Impact: How War Disrupts Oil Supply

This is the most obvious channel. War physically breaks things. When conflict erupts in an oil-producing region, several things can happen that tighten global supply and push prices up.

Infrastructure Damage. Pipelines, refineries, and export terminals are giant, fragile targets. A single missile strike can knock out a facility processing hundreds of thousands of barrels per day. The repair timeline isn't days; it's months or years. This isn't speculation. Look at the repeated attacks on energy infrastructure in the Gulf region over the past decades.

Sanctions and Embargoes. Modern warfare often includes economic weapons. Sanctions on a major producer like Russia or Iran aim to cripple their war machine by cutting off oil revenue. But it also physically removes that oil from the global market, unless other producers can fill the gap. The effectiveness and price impact depend entirely on whether alternative supplies exist and can be mobilized quickly.

Transportation Risks. Key shipping chokepoints become insurance nightmares. The Strait of Hormuz, the Bab el-Mandeb, and the Suez Canal have all been flashpoints. When Houthi militants attack ships in the Red Sea, shipping companies reroute around Africa. That adds weeks to voyages, millions in extra fuel costs, and those costs get passed down the chain, eventually landing at the pump. Insurance premiums for vessels in war zones skyrocket, adding another layer of cost.

But here’s a nuance most people miss: the market often prices in the risk of war long before the first shot is fired. If traders believe there’s a 30% chance of a conflict disrupting supply, they’ll bid prices up by some percentage reflecting that risk. Sometimes, when the war actually starts, the outcome is clearer (and less catastrophic for oil) than the uncertainty, and prices can actually fall. This “buy the rumor, sell the news” pattern is common.

Beyond Supply: Other Factors That Influence Gas Prices During War

Focusing only on supply is a rookie mistake. To understand if gas goes up during a specific war, you have to look at the global chessboard. Here are the other pieces in play.

Global Demand Health. A war’s impact is magnified if the world is already thirsty for oil. In 2022, demand was recovering strongly from the COVID pandemic. The loss of Russian oil hurt more because there was little spare capacity to replace it. Conversely, if a war starts during a global recession (like in 2008-2009), weak demand can completely offset supply fears, muting any price spike.

OPEC+ Decisions. This cartel holds the keys to the world’s spare production capacity. Their response is critical. If they decide to increase production to stabilize the market, as Saudi Arabia and the UAE did partially in 2022, it can put a ceiling on prices. If they hold production steady or even cut (perhaps for political reasons), prices have room to run much higher.

Strategic Petroleum Reserves (SPRs). The US and other IEA members can release oil from their emergency stockpiles. The massive 180-million-barrel release in 2022 was a direct attempt to cool prices after the Ukraine invasion. It worked for a while, acting as a psychological and physical buffer. But SPRs are a finite tool; you can only draw them down so far before you have to refill them, which creates future demand.

Dollar Strength. Oil is priced in US dollars. When geopolitical turmoil sparks a “flight to safety,” investors buy US Treasuries, strengthening the dollar. A stronger dollar makes oil more expensive for countries using euros, yen, or pounds, which can dampen global demand and partially counter supply-driven price increases. It’s a complex feedback loop.

Speculation and Fear. Never underestimate raw emotion. Futures markets are driven by human psychology. Panic buying, whether by hedge funds or physical traders securing cargoes, can create a short-term price spike that exceeds what pure fundamentals justify. I’ve seen it blow past rational models more times than I can count.

The table below shows how these factors interacted in different conflicts. Notice it's never just one thing.

Case Studies: What History Teaches Us

Let’s zoom in on two contrasting examples. This is where theory meets reality.

The 2003 Iraq War: The War That Didn’t Move Prices

In the months before the March 2003 invasion, oil prices climbed steadily, from around $25 to nearly $40 a barrel. Fear was the driver. Traders feared Saddam would torch the oil fields as in 1991, or that the war would drag on and destabilize the entire Middle East.

Then the invasion happened. It was swift. The “shock and awe” campaign secured key infrastructure relatively quickly. Iraqi oil exports, while disrupted, weren't wiped out. Simultaneously, a major oil strike in Venezuela that had constrained supply ended. Most importantly, global demand was still shaky from the dot-com bust and 9/11.

The result? The market had priced in a worst-case scenario that didn't materialize. By the end of 2003, oil prices were back near $30, and the US national average gas price, after a brief jump, settled lower than it was before the war started. The lesson: if the war’s reality is less severe than the pre-war fear, and other market conditions are soft, prices can deflate.

The 2022 Russia-Ukraine War: The Perfect Storm

This was the opposite scenario. Russia is a petro-state and one of the world's top three crude producers and largest natural gas exporter. The pre-war fear was significant, but the reality was worse for energy markets.

The West imposed unprecedented sanctions on Russia's financial system and, later, its oil exports. Even without formal sanctions, many Western companies “self-sanctioned,” refusing to buy Russian oil. This physically removed millions of barrels per day from traditional markets. Russia eventually rerouted much of it to India and China, but at a steep discount and with higher shipping costs, keeping global supply tight.

Critically, demand was roaring back from COVID lockdowns. OPEC+ was increasing production only slowly. Refining capacity in the US and Europe had been reduced during the pandemic. Every part of the system was strained. The massive SPR releases helped, but they were a temporary patch. Prices didn't just spike; they reset to a new, higher plateau for over a year, fueling global inflation.

How to Protect Your Wallet When Geopolitical Tensions Rise

You can't stop a war, but you can avoid getting blindsided at the pump. Here’s a practical, non-preachy guide based on what actually moves prices.

Don't Panic Fill. I’ve seen people rush to fill every container they own when news breaks. This creates a local demand shock that makes prices jump faster and higher than they otherwise would. It’s self-defeating. Keep your tank between half and full as a normal practice, not in a frenzy.

Use Price Tracking Apps. Apps like GasBuddy or Waze show real-time prices. Prices can vary by 30-50 cents per gallon within a few miles. During volatile periods, this search is worth the five minutes. Stations near highways or in affluent areas are often the last to lower prices and the first to raise them.

Understand Your Local Market. Gas prices are hyper-local. They depend on the refinery that supplies your region, state taxes, and local competition. A war disrupting crude in the Middle East will hit the US West Coast (which imports more Middle Eastern crude) harder and faster than the Gulf Coast, which is drowning in domestic and Latin American oil. Follow local energy news.

Consider Your Driving Habits. This is the only real control you have. Combine trips, ease off the aggressive acceleration, and check your tire pressure. Under-inflated tires can cut your mileage by a few percent. It sounds trivial, but over a year of high prices, it adds up.

Look Beyond the Headline. When a new conflict erupts, ask: Is it in a major oil-producing region? Is the producer a swing supplier or a marginal one? What’s the global inventory situation? A war in Sudan will move markets differently than a war in Saudi Arabia. This context helps you gauge whether the spike will last weeks or months.

Finally, remember that markets adapt. High prices incentivize conservation, alternative energy investment, and increased production elsewhere. The initial shock is often the worst part.
