Oil has crossed the psychological $100-a-barrel threshold again, but the more important number for the global economy may be the price at which it eventually peaks — and, more importantly, how long it stays there.
Brent crude surged to almost $110 a barrel this week before retreating towards $105, while West Texas Intermediate briefly moved above $100. The retreat has provided some relief to financial markets. However, it has not removed the underlying problem: oil supplies remain severely disrupted, inventories are falling, and the Strait of Hormuz remains largely closed.
The immediate question is whether Brent can reach $120 or $125.
The more serious question is whether the world economy can absorb oil above $100 for months.
The most common assessment is that $120-$125 is now a realistic next peak if the current disruption persists.
A move to $150 cannot be dismissed if the Strait of Hormuz remains severely constrained, shipping attacks intensify, or if the additional production is lost due to disruptions in other waterways such as Bab el Mandeb.
But $150 is not the central economic danger.
The real danger is an oil price that remains above $100 long enough to force central banks to fight inflation while economies are already losing momentum.
Market tighter than the headline price
The latest data show why the present oil shock cannot be treated as another temporary geopolitical spike.
The International Energy Agency says the disruption has created the largest supply shock in the history of the global oil market. It has disrupted roughly 20 million barrels a day of crude and petroleum products normally passing through the Strait of Hormuz — about one-fifth of global oil consumption. Those flows have fallen to a trickle.
The agency’s latest assessment is even more troubling. It now expects global oil supply to fall by 5.7 million barrels a day in 2026. The demand is projected to decline by 2.5 million barrels a day as high prices begin destroying consumption. Supply recovery has been pushed into 2027.
That is an extraordinary adjustment. It means the market is not simply dealing with expensive crude. It is dealing with a shortage of crude, refined products and transportation capacity.
Diesel and jet fuel are particularly important because their prices feed directly into freight, aviation, agriculture, manufacturing and food distribution. Refining constraints can therefore make the economic impact considerably larger than the headline crude price suggests.

Global inventories provide another warning. The IEA reported that observed oil stocks fell by 69 million barrels in July and were already 410 million barrels below their level at the start of the war.
The world has less of a cushion than it had when this crisis began.
Where could oil peak?
There is no precise mathematical ceiling for oil during a geopolitical supply crisis.
Markets price fear, scarcity and uncertainty simultaneously. At around $105, oil is already high enough to damage consumption. At $120-$125, the inflationary consequences become substantially harder for governments and central banks to ignore.
That is why the next probable peak is seen in the $120-$125 range if the current disruption continues.
A move to $150 would require a significantly worse scenario: a prolonged shutdown of major Gulf exports, further attacks on energy infrastructure, a deeper collapse in tanker traffic or the simultaneous loss of several alternative supply routes.
Yet the market does not need to reach $150 to produce a global economic shock. That distinction is crucial. A brief spike to $120 could be absorbed. Oil averaging $110 for six months would be far more damaging.
From oil to interest-rate shock
This is where the story moves from energy markets to the global economy. Oil increases the cost of transportation, manufacturing, electricity generation and petrochemicals. Households pay more for fuel and have less money available for other goods and services.
Is the world heading for another 2008?
Not necessarily. In fact, that is probably the wrong comparison.
The global financial crisis of 2008 was fundamentally a banking and credit crisis. Excessive leverage, bad mortgages, complex financial instruments and collapsing confidence threatened the solvency of major financial institutions.
Today’s threat is different. The world is encountering the possibility of a stagflationary crisis — a combination of high inflation, weak growth, restrictive monetary policy, falling purchasing power and rising financial stress.
That could ultimately become a financial crisis, but the transmission mechanism would be different.
Emerging markets face the greatest danger
The richest economies have more tools to absorb an oil shock. They can draw on strategic reserves, borrow in their own currencies, subsidise consumers and access deep financial markets.
Many emerging economies cannot. For an oil-importing country with a weak currency, every increase in crude prices creates a double shock.
The country pays more for energy in dollars while simultaneously paying more in local currency because its exchange rate is under pressure. The current-account deficit widens. Foreign-exchange reserves decline. Inflation rises. Interest rates may have to remain high. Economic growth slows.
For heavily indebted economies, the combination can become dangerous very quickly.
This is why an oil shock does not have to cause a banking collapse in New York or London to produce a global financial crisis. It can begin with balance-of-payments stress in weaker economies and gradually spread through currencies, sovereign debt and international banks.
