Global Market Update: Trump’s Impact and Oil Price Surge

Global oil prices surged on April 2, 2026, following a national address by US President Donald Trump on April 1, in which he threatened to conduct extremely hard strikes against Iran over the next two to three weeks. The escalation in rhetoric, combined with an ongoing blockade of the Strait of Hormuz, triggered sharp increases in crude benchmarks and volatility across international equity markets.

Brent crude, the international benchmark, climbed to $107.60 per barrel on April 2, representing a nearly 7% increase, before continuing to rise above $109 per barrel. West Texas Intermediate (WTI) crude saw a more significant jump, rising 8.2% to $108.36 per barrel on April 2. WTI prices later climbed to $109.40 and eventually pushed higher than $111 per barrel, marking the largest one-day price increase for US oil in six years.

Supply Disruptions and the Strait of Hormuz

The price volatility is closely tied to the status of the Strait of Hormuz, a critical maritime passage for global energy flows. The waterway remains largely blocked, a development that has halted approximately 20% of global oil shipments. The conflict, which began roughly one month prior to April 1, has created significant anxiety regarding the long-term security of Middle Eastern energy supplies.

In his April 1 address, President Trump stated that the United States does not rely on energy from the Middle East and urged other nations to take action to maintain Gulf oil shipments. However, the speech did not provide a structured path toward a ceasefire or a clear exit strategy from the conflict, which analysts suggest has faded hopes for a rapid resolution.

Market Volatility and Downstream Impacts

The surge in crude costs has moved rapidly into downstream fuel prices. On April 2, the price of unleaded gasoline rose to $3.31, an increase of 7.14%. The nationwide average price for unleaded gas in the United States reached $4.08.

Financial markets reacted with instability. Asian and European equities saw declines as investors weighed the risks of prolonged supply disruptions. In the United States, major indexes experienced sharp early losses on April 2 before partially recovering. By the close of trading on April 2, the S&P 500 was up 0.11% and the Nasdaq Composite rose 0.18%, while the Dow Jones Industrial Average fell 61 points. The Russell 2000 index rose 0.7%.

The aviation sector has also felt the impact of rising jet fuel costs. Asian airlines have responded by cutting flights and increasing ticket prices to offset the pressure on operating margins.

Diplomatic and Military Responses

International efforts to secure maritime trade are accelerating. UK Prime Minister Keir Starmer announced a virtual summit involving nearly 36 countries to discuss measures to ensure safe navigation through the Strait of Hormuz. More than 40 countries attended a virtual meeting on April 2 to discuss the full reopening of the waterway.

On the diplomatic front, the UN Security Council was scheduled to vote on April 3, 2026, on a proposal from Bahrain. The proposal would authorize member countries to use all defensive means necessary to secure the Strait of Hormuz.

Military movements have also intensified. On April 2, 2026, the USS Gerald R. Ford, the largest aircraft carrier in the US Navy, departed from Split, Croatia. The vessel had been undergoing repairs following a fire in its laundry spaces on March 12 while operating as part of Operation Epic Fury against Iran.

Iranian Position and Outlook

Despite the military pressure, US intelligence assessments indicate that Iran maintains significant missile launching capabilities following more than a month of US-Israeli bombardment.

Some market optimism emerged on April 2 after Iran’s deputy foreign minister stated that his country would outline a new navigation regime in the Strait of Hormuz once the war ended. While this comment helped stabilize some US stock indexes, it had little immediate effect on oil prices, which remained elevated due to the immediate threat of further strikes and the ongoing blockade.
