What Actually Moves Oil Prices

Most people associate the price at the pumps with what's happening with crude oil right now — which isn't really the case. The price of oil is set to the future: what are we anticipating will happen? Do we think supply will outweigh demand, or the other way around? The number you see is a quote for the future, and that's an important piece to remember.

Supply and demand is the engine

Oil is like everything else — driven by supply and demand. Not enough oil, price goes up. Too much oil, price goes down.

The tricky part is when you see something on the news — a conflict, an OPEC announcement, a pipeline issue — it can look like that news is the driver. Technically, it's not. The driver is people's assumptions about what this news means for the future of oil, which gets reflected back to us in how much it costs to fill our cars at the pump.

Geopolitics: real, but watch whether it actually happens

Geopolitics is a legitimate signal that can affect the price of oil — that said, there are different ways to look at it.

For example, there's a threat we all see on our news channels, and you notice the price of oil goes up, even if that threat never comes to fruition. What it did was excite the market and create a price jump out of fear — not supply and demand. It's a blip, and prices will correct accordingly.

Now, sometimes these threats do come to fruition. For example, in early 2026 there were tensions around the Strait of Hormuz — the narrow waterway that roughly a fifth of the world's seaborne oil passes through — in which shipping was genuinely disrupted. Tankers were unable to move through the Strait, leading to a lack of supply, and therefore an increase in pricing.

So it's important to see these geopolitical signals and watch closely, while also asking: are barrels actually moving, or is there genuine disruption? The headlines don't tend to focus on that part.

Oil is only one piece of the puzzle

Barrels of crude being pumped out of the ground don't directly correlate to gasoline in your tank. There's a refining and transport process in between. Oil production might not be affected, but transport and refining can have their own issues that lead to price changes.

For example, let's say a major refinery goes offline. There might be a ton of supply of crude barrels, but if they can't be refined, then they sit in storage and never become usable fuel. It's important to notice all parts of the chain to avoid a nasty surprise at the pump.

OPEC matters, but it isn't the whole story

OPEC is not the puppeteer some might assume. Yes, it can cut supply and increase prices — however, this is not an isolated incident. OPEC cuts, but producers may decide to drill more, leading to an increase in supply. The price may not rise as much as the initial announcement led the public to believe — another blip in price.

Why wells need constant replacement

Many people imagine these oil wells pumping tons of black gold out of the ground constantly. While that's the dream, it's not the case. Oil wells start strong with high production, but decline rather quickly — not a malfunction, producers plan for this.

This means there's a constant stream of new wells being drilled — not to grow production, but to hold it where it is today.

Now, remember that oil prices today are future estimates. If drilling slows due to financial issues, regulatory changes, or sustained low oil prices that make new wells uneconomic for companies to drill, supply decreases. Lower supply, higher prices — but the market starts pricing that in well before you'd see it at the pump.

WTI vs. Brent

There are two major benchmarks relating to crude oil you'll see. The first is WTI (West Texas Intermediate), the U.S. benchmark. Brent is the international one, and most of the world's oil is priced off Brent. If you're in North America, WTI is the more relevant number for you; if you're trying to understand global oil, Brent is the reference point. They move together most of the time, but they're answering slightly different questions.

What to actually watch

Since current oil prices are a bet on future supply and demand, it's important to watch for actual indicators, not just current sentiment.

Consumption — how much oil the world is actually using. A dramatic example: during COVID, when everyone stayed home, demand collapsed so hard that on April 20, 2020, WTI crude traded at a negative price for the first time in history — bottoming around negative $37 a barrel. Producers were effectively paying buyers to take oil off their hands. Part of what made it go negative rather than just cheap was storage: tanks were so full that holders of expiring futures contracts had nowhere to physically put the oil.

Storage — how much oil is in the buffer zone. When storage is high, any supply scare has a cushion, and pricing may not react as much as expected. When storage is low, the same scare hits much harder.

Headlines — here's the dramatic piece. Conflicts, threats, and announcements matter and will affect prices, but they aren't the only lever. Pay attention, but do your due diligence. The headline gets your attention; the consumption and storage numbers tell you whether to believe it.
