Oil Traders Shorted Brent Crude Before Trump’s April 21 Truth Social Post
The trades, reported on by Reuters, involved the aggressive sale of 4,260 lots of Brent crude futures between 19:54 and 19:56 GMT, during post-settlement hours when market liquidity is typically thin. At prevailing prices near $100.91 per barrel, the position carried approximately $430 million in notional value.
At 20:10 GMT, Trump posted on Truth Social that the ceasefire would be extended indefinitely. He cited Pakistan’s mediation, crediting Field Marshal Asim Munir and Prime Minister Shehbaz Sharif for requesting the delay. He also described Iran’s government as “seriously fractured” in the post.
Brent crude fell to a session low of $96.83 per barrel within minutes of the announcement. Prices partially recovered during early April 22 trading, hovering between $99 and $101, as reports of Iranian ship seizures in the Strait of Hormuz kept markets on edge.
The April 21 event is the fourth in a pattern of large, well-timed oil short positions tied to Trump administration announcements on the Iran conflict, according to several news outlets, including the BBC. On March 23, traders placed roughly $500 million in bets on falling prices about 15 minutes before Trump announced a pause on strikes against Iranian energy infrastructure.
On April 7, a position worth approximately $950 million was placed hours before the initial two-week ceasefire was announced. On April 17, a $760 million bet preceded Iran’s foreign minister announcing that the Strait of Hormuz would reopen to commercial shipping.
April 2026 bets alone total approximately $2.1 billion in notional value.
The Commodity Futures Trading Commission (CFTC) is investigating trades from at least the March 23 and April 7 events. The CFTC has requested trading data from CME Group and Intercontinental Exchange. ICE declined to comment on the April 21 incident. No charges have been publicly filed as of today, and it is unclear whether the latest trades have been added to the existing probe.
The White House has warned staff against using non-public information to place market bets, according to reports. Profits from earlier trades have been estimated in the tens of millions of dollars.
Market analysts and financial journalists have pointed to these trades as potential evidence of insider information. Financial Times, Reuters, and BBC coverage of prior incidents used language such as “mind-blowing” when describing the timing and directional accuracy of the positions.
The TACO Trade
The broader trading strategy is sometimes called the TACO trade, a term coined by Financial Times columnist Robert Armstrong in 2025. The name stands for “Trump Always Chickens Out,” and it describes a pattern of Trump issuing very aggressive threats before pulling back, creating predictable relief rallies in equities and sell-offs in oil prices.
The most recent TACO serving took place yesterday, April 21, a Tuesday, mirroring the prior TACO trade that also occurred the Tuesday before. This pattern of Tuesday activity has sparked a running joke tied to “Taco Tuesday,” the widely recognized day when many people indulge in the Mexican dish.
The TACO trade has been applied repeatedly during the 2026 Iran conflict. Trump’s tough rhetoric on strikes and Hormuz deadlines pushed Brent toward the $100-per-barrel range, while de-escalation announcements triggered sharp drops. On April 8, Brent fell as much as 16% in a single session, its biggest one-day decline since 2020, after the initial ceasefire was announced.
The current ceasefire, however, remains fragile. Iran has not formally agreed to the extension on U.S. terms. Tehran has conditioned further negotiations on lifting the U.S. naval blockade, sanctions relief, and additional concessions. Iranian forces have seized commercial vessels in the Strait since the extension announcement. Peace talks in Pakistan have stalled.

The Strait of Hormuz carries roughly 20% of the global oil and liquefied natural gas supply. Any disruption to traffic there has an immediate effect on global energy prices, giving each diplomatic development an outsized market impact.
Regulators have not confirmed illegal activity in connection with any of the trades reviewed by Reuters and other journalists so far. The pattern, the timing, and the size of the positions have drawn continued scrutiny from investigators and market observers alike.
