Inside Information? $580 Million in Abnormal Trading Activity Appears in Crude Oil Futures Market 15 Minutes Before Trump's Post

U.S. President Trump claimed that the United States and Iran had held “productive talks,” but this statement was quickly denied by Iran. About 15 minutes before this “he said, she said” drama unfolded, the crude oil futures market saw an unusually large trade valued at up to $580 million, prompting market participants to suspect insider trading.

On the evening of March 23, global financial markets once again experienced sharp fluctuations following a social media post by President Trump.

Trump posted on Truth Social, claiming that the U.S. and Iran had held “productive discussions,” and announced a five-day delay in plans to strike Iran’s energy infrastructure.

Immediately, European and U.S. stock markets rose, international oil prices fell, and precious metals rebounded quickly.

However, Iran firmly denied the claim, with Iran’s Islamic Parliament Speaker Ali Larijani posting on social media that it was “fake news” aimed at “manipulating financial and oil markets.”

Just 15 minutes before this “he said, she said” episode, the oil futures market saw a massive, unusual trade worth $580 million, with the S&P 500 futures nearly simultaneously experiencing a surge in volume.

The timing, cross-asset synchronization, and subsequent precise message release led to widespread speculation of insider trading on Wall Street.

White House spokesperson Kush Desai quickly denied the rumors, stating that any unverified insinuations are “baseless and irresponsible reporting.”

Strange Trade

Between 6:49 and 6:50 a.m. New York time on March 23, about 6,200 Brent and WTI crude oil futures contracts changed hands within one minute, totaling a nominal value of $580 million.

According to calculations by the Financial Times based on Bloomberg data, this batch of trades occurred within 27 seconds before 6:50 a.m. Almost simultaneously, the trading volume of the S&P 500 e-mini futures on CME spiked, with prices jumping within seconds. At that time, no major news was released that could justify such extreme volatility.

About 15 minutes later, at 7:04 a.m. NY time, Trump posted on social media that the U.S. and Iran had conducted “very good and productive talks” over the past two days, and announced a five-day delay in plans to strike Iran’s power plants and energy infrastructure.

Following this, global energy markets plummeted, with Brent crude dropping over 13%, falling below $100 per barrel; U.S. stock futures surged, with the S&P 500 futures pre-market rising over 2.5%.

Trump’s remarks were immediately denied by Iran. Iran’s Parliament Speaker Ali Larijani posted on social media that “no negotiations have taken place with the U.S.,” calling the reports “fake news” aimed at “manipulating financial and oil markets to help the U.S. and Israel escape current difficulties.” Iranian Foreign Ministry spokesperson Saeed Khatibzadeh also emphasized that although Iran received some friendly messages in recent days, “no negotiations have taken place with the U.S.”

This $580 million abnormal trade led market participants to suspect insider trading. A hedge fund manager with 25 years of experience said, “From my market intuition, this is clearly abnormal. There were no major data releases or Fed officials’ speeches worth rushing for on Monday morning. For a day with no event risk, this was an unusually large trade… Someone just made a lot of money.”

While a single trade may not necessarily be illegal, the pattern of “cross-asset, same time, near major policy statements” is enough to attract regulatory scrutiny. However, according to foreign media reports, there is currently no public evidence that the SEC or CME has launched an official investigation.

Overdrawing Credibility

In response to widespread skepticism, a White House spokesperson stated: “The White House does not tolerate any government officials profiting illegally from insider information. Any unsubstantiated claims implying officials are involved are baseless and irresponsible.”

This response aimed to cool the situation, but it’s not the first time markets have seen abnormal trading before major Trump statements. On issues like trade wars, Fed personnel changes, and Greenland disputes, Trump’s unpredictable behavior has repeatedly triggered market declines followed by rebounds, creating arbitrage opportunities for insiders or related parties familiar with his pattern.

In April last year, about four hours before Trump announced tariff adjustments, he tweeted, “This is a great buying opportunity!” The Trump Media & Technology Group’s stock closed up 22.67% that day, and Trump’s personal wealth surged by $415 million in a single day. Democratic lawmakers called for congressional investigations at the time.

This time, although there’s no clear evidence of direct involvement by White House officials, the market has already internalized Trump’s “erratic” style into a unique pricing logic.

For Wall Street, whether Trump’s statements are true may not matter. The market’s sharp rebound isn’t because investors blindly believe his “ceasefire” words, but because they see it as a reassurance: Trump’s extreme aversion to poor economic data will ultimately prevent him from taking more drastic military actions.

RBC Wealth Management senior portfolio strategist Tom Garretson said, “Trump has been clearly trying to suppress oil prices.”

BCA Research chief strategist Marko Papic added, “If this isn’t resolved within the next 7 to 10 days, we could face a global economic standstill. Today’s statement shows Trump realizes the real economy might be on the brink of a cliff.”

Westwood Capital managing partner Daniel Alpert pointed out that markets are not based on facts but on expectations. Even if investors suspect it’s a lie, as long as they believe others will see it as good news and buy in, they will follow suit.

However, the cost of Trump’s unpredictability is becoming apparent. Increasingly, institutional investors worry that Trump is eroding the credibility of the U.S. presidency in the global financial markets.

Piper Sandler chief investment strategist Michael Kantrowitz noted that truth depends on perception, and Trump’s unpredictability only adds to uncertainty.

JPMorgan former chief quantitative analyst Marko Kolanovic said that in a war scenario, the “TACO trade” might fail.

“TACO” stands for “Trump Always Chickens Out,” meaning investors bet that Trump will ultimately back down during market volatility or policy panic, thus pushing risk assets higher.

Kolanovic believes tariffs are executive policies that can be reversed with a tweet; but once war begins, it gains its own momentum, involving powerful forces beyond any single leader’s control.

Mizuho Bank strategist Jordan Rochester wrote in a report: “The hardest part isn’t predicting war, but predicting how the White House will respond. We’re facing a confused market, uncertain whether this is a credible sign of approaching endgame or just another ‘very thorough, almost certain’ moment.” This uncertainty makes every market move triggered by Trump’s comments more like a gamble based on information asymmetry rather than fundamental analysis.
