Three Physical Barriers That Will Control Oil Prices
Oil prices are notoriously difficult to predict. The market has a long history of undermining anyone who speaks with too much confidence. There are too many variables involved.
At the end of 2025, the prevailing narrative was that the remaining oil was expected in 2026. Several major banks and forecasting agencies expected global supply to exceed demand by several million barrels per day. Some forecasts—including this one from JPMorgan Chase—expected Brent crude to drift into the $60 range by mid-2026.
How quickly things change.
Following a week of escalating conflict in the Middle East and the closure of commercial traffic through the Strait of Hormuz, West Texas crude rose above $110 per barrel as a number of traders grew concerned about the country. That’s its highest level since the 2022 price shock following Russia’s invasion of Ukraine. But those moves may only indicate the early stages of a potential power shock if tensions continue.
While that price remains well below the record levels seen in 2008, the dynamics of the exchange today are different. Instead of debating whether disruption is possible, markets are reacting to what has already happened.
The question that many students are asking right now is simple: How high could oil prices go?
The honest answer is that no one knows for sure. But we can assess the possibilities by looking at the three constraints that ultimately rule oil markets: spare capacity, the need to expand, and the limits of policy intervention.
The first obstacle is the global supply buffer.
By the end of 2025, the world had about 3 to 4 million barrels per day of remaining active production, which is almost exclusively held by Saudi Arabia and the United Arab Emirates.
Under normal circumstances, that cushion helps stabilize prices during temporary disruptions.

But the scale of the Strait of Hormuz puts that buffer in its sights. About 20 million barrels a day—about one-fifth of the world’s oil consumption—move through that narrow waterway.
Even if all backup power banks were brought online immediately, it would remove only a fraction of the volume currently at risk.
In other words, backup power can help smooth out minor disruptions. You cannot fully compensate for a systemic chokepoint affecting such a large share of global supply.
Sometimes when people ask me how high oil prices are, I ask a different question: How much does gas have to cost before you start driving slowly?
That thought experiment captures a fundamental truth about oil markets.
Demand is resilient in the short term. People still go to work, trucks still deliver goods, and planes still fly.
But at some point, high fuel costs start to change behavior. Consumers are driving less, businesses are cutting back on sight-seeing, and economic growth is slowing.

History provides a useful benchmark. In 2008, WTI crude rose to $147 per barrel just before the global economy went into recession. Many analysts now view around $120 per barrel as a “recession trigger”—the level at which energy costs begin to meaningfully erode consumer spending and economic momentum.
In that sense, higher prices eventually become their way of self-correction. They suppress demand until the market balances. Or, as the saying goes, the solution for high prices is high prices.
Policy instruments can also influence prices—but only within limits.
The US Strategic Petroleum Reserve currently holds approximately 415 million barrels of crude oil. While that is still one of the largest emergency reserves in the world, it is well below the peak of more than 700 million barrels seen 15 years ago.
Scheduled releases from the SPR could help calm markets and end temporary disruptions, as happened after Russia’s invasion of Ukraine. For example, a reduction of one million barrels per day can temporarily increase supply during a crisis.
But compared to the nearly 20 million barrels a day that regularly travel through the Strait of Hormuz, even aggressive releases are causing little disruption.
SPR can buy time for markets to adjust. It cannot replace the Persian Gulf.
Instead of trying to predict a precise target price, it is more useful to think of a range that corresponds to real-world developments.
Content disruption ($90–$110 WTI). If the current disruption proves temporary and shipping through the Strait resumes quickly, the current price increase may disappear as the previously anticipated 2026 surplus reasserts itself.
Structural shock ($110–$130 WTI). If the disruption continues for several weeks – through tanker strikes, infrastructure damage, or prolonged insurance withdrawals – the market will begin to price the risk of continued supply.
Big upset ($140+ WTI). This situation may require a major escalation, such as major damage to key processing facilities in Saudi Arabia or the UAE. At that point the market will be driven less by trading sentiment and more by the global scramble for virtual barrels. At that time, we don’t really know how high oil prices are, but at some point, they will trigger an economic response.
Oil markets are finally correcting themselves. High prices often sow the seeds of their own recession by reducing economic activity and reducing demand.
But that repair process can take time—and it can be painful.
The key question right now is not whether oil prices will rise. History shows they can.
The real question is how long the global economy will survive those prices before the destruction of demand forces the market back into equilibrium. And most importantly, what those impacts on the global economy will ultimately be.
