Bitcoin and other high-risk assets have shown a pronounced sensitivity to the statements and actions of U.S. President Donald Trump, with market fluctuations often occurring within minutes of his social media updates or public declarations. This phenomenon has raised alarms among lawmakers, academics, and market analysts, who are increasingly questioning whether these rapid price movements create avenues for market manipulation or insider trading.
A recent study from the University of Oxford’s Faculty of Law highlighted significant volatility in global markets following fluctuating U.S. tariff policies. The study noted a sequence where both cryptocurrency and stock prices fell sharply after new tariffs were introduced, only to rebound when Trump rolled back some of those tariffs a few days later. The timing and magnitude of these swings raised concerns about what the study describes as “fantastic trading opportunities” for individuals with prior knowledge of such decisions. This back-and-forth dynamic has since been dubbed the “Trump Again Chickens Out” or TACO phenomenon.
The scrutiny intensified in April 2025, when Trump made a post on Truth Social that read, “THIS IS A GREAT TIME TO BUY!!” shortly before announcing a tariff adjustment that resulted in a significant market uptick. This scenario pushed lawmakers, including Senator Adam Schiff, to call for investigations into potential insider trading or manipulation of the markets. Analysts have noted unusual patterns of timely trades in commodities and prediction markets, often made mere minutes before critical policy or military-related announcements.
As reported in a March episode of CBC’s Front Burner, many experts believe that the Trump administration may be engaging in market manipulation, with examples like unusually profitable oil future trades ahead of announcements relating to military actions. Congressman Stephen Lynch echoed similar sentiments, stating that trading activity associated with major Trump announcements raises serious concerns regarding insider trading and market manipulation by officials privy to sensitive information.
While no evidence has surfaced indicating that Trump or his administration has explicitly violated securities laws or intentionally manipulated the markets for personal gain, the increasing frequency of remarkably timed market movements, alongside the administration’s significant influence over policymaking and regulations, has ignited a broader discussion about the blurred lines between political action and market impact.
The analysis also outlines five key moments when Bitcoin’s price saw pronounced swings triggered by Trump’s statements:
-
July 11, 2019 — “Not a Fan” Genesis Post: Trump’s declaration that he was “not a fan” of Bitcoin and cryptocurrencies caused Bitcoin to plummet by 7.1% within 45 minutes.
-
March 3, 2025 — Strategic Reserve Pivot: Following a pro-crypto campaign season, Trump’s announcement about including Bitcoin in a “Strategic National Crypto Reserve” saw Bitcoin surge by 8.2% in less than 24 hours.
-
October 10, 2025 — 100% Tariffs on China: A Truth Social post announcing hefty tariffs led to a significant decline of 12.4% in Bitcoin’s value within roughly two hours, resulting in a historic $19.38 billion liquidation.
-
March 3, 2026 — Anti-Bank “Genius Act” Post: Trump criticized Wall Street banks over delaying legislation related to cryptocurrencies, triggering a quick 5.2% spike in Bitcoin’s price within just 10 minutes.
-
April 14, 2026 — Peace Talks: Following tensions related to naval blockades, Trump stated that Iran reached out for peace talks, propelling Bitcoin’s value by 6.2% in 30 minutes.
Bitcoin recently climbed to a two-month high of over $78,000 after Trump suggested the end of a military conflict and the reopening of the Strait of Hormuz. However, by the end of the day, uncertainty lingered over the terms of the agreement, and as of Saturday morning, reports indicated the Strait was again closed, leading to a retreat in crypto prices back below $76,000. As the impacts of Trump’s announcements continue to reverberate through the markets, questions regarding the integrity of trading practices remain at the forefront.
