Oil Volatility Spikes as Trump’s Shifting Iran Strategy Keeps Markets on Edge

President Donald Trump announced late Saturday that he would halt planned attacks on Iran to facilitate renewed talks aimed at de-escalating the conflict and restoring stalled cargo traffic through the Strait of Hormuz. This decision marks the latest in a pattern of announcements where the U.S. president first threatens massive strikes and later calls them off. These abrupt shifts have been a defining feature of the five-month conflict, sending prices of oil and basic goods soaring and keeping global markets on edge.

A Pattern of Volatility: Market Whiplash

Trump's stop-and-start strategy creates unpredictability for investors while amplifying volatility in commodity prices. The trajectory of the conflict exacerbates concerns regarding energy supply security.

■Announcements from the U.S. president temporarily boost optimism for an end to the war, but renewed attacks days or even hours later upend these expectations.

■Shipping risks in the Strait of Hormuz directly impact logistics costs and insurance premiums, triggering global inflationary pressures.

■Markets struggle to price assets effectively amidst this uncertainty, oscillating between diplomatic hopes and military escalation.

Timeline of Escalation and Retreat

Key events illustrating the fluctuating nature of the U.S. approach toward Iran highlight the risks facing global trade and energy routes:

■April 7: The U.S. and Iran agreed to a two-week ceasefire to end intense fighting. Trump announced the pause less than two hours before a deadline he had set for Tehran to capitulate or face attacks on bridges and power plants.

■April 21: Trump announced the indefinite extension of the ceasefire just before it was set to expire. The fragile truce lasted until May 8, when the U.S. carried out strikes on Iranian tankers.

■May 18: Following a weekend of threats, Trump stated he was holding off on a major strike due to "serious negotiations." However, by May 27, U.S. strikes were back on after negotiations faltered.

■June 11: After days of back-and-forth attacks, Trump threatened to hit Iran "VERY HARD TONIGHT" and take control of its oil and gas industries. Hours later, he called off the strikes citing a breakthrough in negotiations.

■June 17: Trump signed an initial agreement for a permanent end to hostilities and the reopening of the strait, initiating a 60-day negotiating clock for Iran's nuclear program.

■July 7: Following Iranian attacks on commercial ships, Trump launched new strikes on Iran while attending the NATO summit in Ankara, threatening to "just finish the job."

■Aug. 1: After threatening to hit Iran "very hard," Trump claimed on social media that Middle East allies had reached a deal to end the war and canceled the planned attacks.

Markets are hypersensitive to this geopolitical "on-again, off-again" approach. Trump’s stop-and-start tactic is embedding a permanent "risk premium" into crude oil. At the EM desk, the picture is clear: energy-importing emerging markets face rising inflationary pressure, while regional risk sentiment oscillates rapidly. Investors must maintain liquidity positions to navigate this erratic news flow.
