The moment Donald Trump posted his 48-hour ultimatum to Iran on Saturday night, energy traders in Asia knew what was coming. Brent crude, which had already been trading above $140 on the back of four weeks of Hormuz disruption, surged past $150 in early Sunday trading. West Texas Intermediate followed. European natural gas futures, already at crisis levels, spiked further.
This is the highest oil has traded since the all-time record of $147.50 set briefly during the 2008 financial crisis. But unlike 2008, where the spike was driven by speculation and demand pressures, today’s prices reflect a genuine and worsening supply crisis. Twenty percent of global oil supply remains effectively locked behind a closed waterway, and the President of the United States has just threatened to escalate the conflict that closed it.
The Market Calculation
Markets are pricing in two scenarios, both of them bad. If Trump follows through on his threat, Iranian retaliation against Gulf energy infrastructure could take additional supply offline — potentially pushing oil toward $200. If he backs down, the Strait of Hormuz remains closed with no clear path to reopening, and prices stay elevated for months.
The IEA’s emergency reserve release of 400 million barrels — the largest in history — has done almost nothing to calm markets. Strategic reserves are a stopgap, not a solution. They buy time. But time is running out if the Hormuz closure becomes a permanent feature of the conflict rather than a temporary disruption.
The Inflation Transmission
At $150 oil, the inflationary impact is no longer limited to energy. Transportation costs surge across every supply chain. Fertiliser prices — already elevated because a third of global fertiliser shipments transit the strait — are feeding through to food prices. Airlines are adding fuel surcharges. Shipping rates are climbing as vessels reroute around the Cape of Good Hope.
The central banks that froze rates last week now face an even uglier picture. Inflation was already rising. At these energy prices, it will accelerate. But raising rates to fight an oil shock would crush growth in economies that are already weakening. The stagflationary trap is tightening.
Consumer Pain
For ordinary consumers, the impact is immediate and brutal. US gasoline prices, already at $3.88, will breach $4 within days if oil stays at these levels. In Europe, where taxes make up a larger share of pump prices, the impact is somewhat cushioned but still severe. Heating costs, electricity bills and food prices will all rise.
The political implications are obvious. Every dollar added to the oil price makes the war in Iran less popular domestically. Every cent on the pump price is a vote lost in November. Trump may believe that threatening Iran will force a resolution. But if it triggers an escalation instead, the economic damage could define the remainder of his presidency.
