Bitcoin and other high-risk assets have increasingly become sensitive to statements from U.S. President Donald Trump. Market movements, either upward or downward, often occur within minutes of his tweets or news announcements. This phenomenon has drawn attention from lawmakers, academics, and market experts who are questioning whether these price swings present opportunities for market manipulation or insider trading. A study by the University of Oxford Faculty of Law identified significant market fluctuations following swift changes in U.S. tariff policy. These included instances where global markets, including crypto and stocks, fell after new tariffs were announced but later rebounded when Trump partially reversed them. The author noted these movements created “fantastic trading opportunities” for those with advance knowledge of the decisions. This pattern has been criticized as the ‘Trump Again Chickens Out’ (TACO) dynamic. After Trump posted “THIS IS A GREAT TIME TO BUY!!” on Truth Social in April 2025 before announcing a tariff adjustment that boosted markets, lawmakers like Senator Adam Schiff called for an investigation into potential insider trading or market manipulation. Analysts and media reports have pointed to patterns of large, well-timed trades across commodities and prediction markets, sometimes occurring minutes before significant policy or military announcements. According to a March episode of CBC’s Front Burner, “Many experts say the Trump administration has engaged in market manipulation,” citing unusually profitable oil futures trades ahead of Iranian war-related announcements. Democratic Congressman Stephen Lynch also raised concerns about trading activities linked to major Trump announcements, suggesting they indicated potential insider trading and market manipulation by government officials with sensitive information. While there is no evidence that Trump or his administration violated securities laws or manipulated markets for personal gain, the unusual timing of market moves combined with direct policy influence has sparked a debate over whether political decisions are increasingly affecting market dynamics. Here are five notable instances when Bitcoin’s price was significantly affected by Trump’s statements or social media posts: 1. July 11, 2019 — “Not a Fan” Genesis Post: In his first direct criticism of cryptocurrencies, Trump tweeted, “I am not a fan of Bitcoin and other Cryptocurrencies, which are not money… and based on thin air.” Bitcoin fell 7.1% within 45 minutes. 2. March 3, 2025 — Strategic Reserve Pivot: After a year of supporting crypto, Trump announced via Truth Social that his “Strategic National Crypto Reserve” would include cryptocurrencies like bitcoin. Bitcoin surged 8.2%, jumping from $84,000 to over $91,000 in less than 24 hours. 3. October 10, 2025 — 100% Tariffs on China: Trump’s Truth Social post announcing a 100% tariff on Chinese imports led Bitcoin to drop 12.4% in about two hours from its all-time high of $124,714 toward $102,000. This resulted in a $19.38 billion liquidation event, the largest single-day loss in Bitcoin’s history. 4. March 3, 2026 — Anti-Bank “Genius Act” Post: Trump criticized Wall Street banks on Truth Social for delaying the Genius and Clarity Acts due to stablecoin yield provisions, prompting a 5.2% increase in Bitcoin within 10 minutes to $71,000. 5. April 14, 2026 — Peace Talks: Following naval blockades of the Strait of Hormuz, Trump mentioned potential peace talks with Iran. Bitcoin rose 6.2% from $70,000 to nearly $75,000 within 30 minutes. Bitcoin reached over $78,000 on Friday after Trump hinted at ending hostilities and reopening the Strait of Hormuz. However, by Saturday morning, Iran’s military declared the strait closed again amid reports of naval confrontations, causing crypto prices to retract Friday’s gains as bitcoin fell back below $76,000.
