Crude Oil Tumbles Over 6% as US-Iran Peace Plan Unwinds War Premium

Global markets repriced geopolitical risk sharply on Wednesday after Washington sent a peace plan to Iran and Tehran announced it would permit “non-hostile” vessels to transit the Strait of Hormuz, offering the first signs of a potential off-ramp to a conflict that has roiled the global economy. The news sent crude prices plunging, with Brent falling more than 6 percent to back below $100 a barrel.

"Markets have tentatively repriced towards a slightly higher probability of de-escalation, but conviction remains low," said Chris Weston at Pepperstone. He noted that reports of additional U.S. troop deployments to the region suggest "developments on the ground do not fully support a de-escalation narrative."

The violent unwinding of the geopolitical risk premium saw both main crude contracts plunge after U.S. President Donald Trump voiced optimism about ending the war. The move was a stark reversal from recent highs near $120 per barrel, which were driven by fears of a full-blown supply disruption. In response to the de-escalation hopes, equity markets rallied, with indexes in Tokyo and Seoul spiking more than 3 percent at one point, while Hong Kong and Sydney also gained.

The Hormuz Chokepoint

The crisis has centered on the Strait of Hormuz, a maritime chokepoint that handles around 20 percent of the world’s daily oil and liquefied natural gas flows. Iran’s blockade of the strait had effectively removed about 15 million barrels per day from accessible global supply, according to the Energy Institute, creating a price surge based on expected disruption rather than current shortages. Oil markets are forward-looking, and the "geopolitical risk premium" added to prices reflects the probability of escalation, sanctions, or shipping disruptions.

The sudden drop in prices illustrates how quickly that premium can be removed. When President Trump signaled a pause in threatened military action, prices fell sharply even though no new oil had entered the market. The shift was driven entirely by changing expectations, a dynamic that makes crude one of the world's most volatile commodities.

Economic Ripples and Strategic Buffers

Despite the blockade's severity, several factors prevented prices from climbing toward the $150 per barrel level that some analysts believed was possible. Major economies like the United States are less dependent on Middle Eastern oil than in past decades due to surging domestic production. Furthermore, strategic petroleum reserves in the U.S. and China have been deployed to cushion the supply gap.

However, the economic impact has already been significant. In the UK, businesses reported the sharpest rise in input costs since 1992, showing how quickly energy shocks fuel inflation. The process works through multiple channels: higher fuel costs raise transport prices, increasing costs for manufacturing and agriculture, which in turn slows economic growth as consumers cut back on other spending.

The geopolitical tensions in the Middle East do not exist in a vacuum. They coincide with a fraught review of the United States-Mexico-Canada Agreement (USMCA), where U.S. economic pressure and tariff threats are creating significant uncertainty for North American supply chains. According to a recent analysis from the Center for Strategic and International Studies, the review process has already contributed to a slowdown in investment in Mexico and job losses in Canada, demonstrating the high cost of trade uncertainty even among allied partners.
