Five key instances where President Trump’s remarks caused Bitcoin to fluctuate, and why similar volatility may occur again this week
President Trump’s comments on social media and to journalists have sparked 5% to 12% price swings in Bitcoin, raising questions about the boundary between policy decisions and market influence.

Key Takeaways:

• Bitcoin and other high-risk assets have become increasingly responsive to President Trump’s online posts and policy declarations, sparking worries about possible market manipulation and insider trading.
• Lawmakers and financial experts have identified a pattern of unusually timed trades surrounding Trump-era tariff changes, military actions, and energy policies, though no proof has surfaced that Trump or his team broke securities regulations.
• A string of Trump’s statements since 2019 has repeatedly caused sharp Bitcoin price movements, and recent volatility linked to conflicting reports on the Strait of Hormuz reopening shows markets remain highly sensitive to his words.

Bitcoin and other risk-sensitive assets have grown more reactive to comments from U.S. President Donald Trump, with prices often shifting dramatically within minutes of his social media updates or policy announcements to the press.

This trend has drawn attention from lawmakers, academics, and market analysts, as concerns grow over whether these price movements have created profitable opportunities for market manipulation or insider trading.

A recent University of Oxford Faculty of Law study highlighted sharp global market swings following rapid U.S. tariff policy changes, including a sequence where crypto and stock prices fell after new tariffs were announced, then recovered after Trump partially rolled them back days later.

The author noted that the scale and timing of these moves created «fantastic trading opportunities» for those with early knowledge of the decisions. Additionally, Trump’s back-and-forth decisions have been widely criticized and dubbed the «Trump Again Chickens Out» (TACO) dynamic.

‘A Great Time to Buy’

The issue gained further attention after Trump posted «THIS IS A GREAT TIME TO BUY!!» on Truth Social in April 2025 shortly before announcing a tariff adjustment that pushed markets higher, prompting calls from lawmakers, including Senator Adam Schiff, for an investigation into potential insider trading or market manipulation.

Analysts, experts, and media reports have highlighted patterns of large, well-timed trades across commodities and prediction markets, in some cases placed minutes before major policy or military announcements.

«Many experts say the Trump administration has engaged in market manipulation,» according to a March episode of CBC’s Front Burner, which pointed to unusually massively profitable trades in oil futures ahead of announcements related to the war with Iran.

Democratic Congressman Stephen Lynch raised similar concerns. He said trading activity tied to major Trump announcements «raised serious concerns about insider trading and market manipulation by government officials in possession of sensitive national security information.»

There is no evidence that Trump or his administration have violated securities laws or purposely manipulated the markets for self gain, but the increasing number of unusually well-timed market moves, combined with the administration’s direct influence over policy, geopolitics and regulation, has fueled a broader debate over whether the line between political decision-making and market impact is becoming increasingly blurred.

Here are five top moments when bitcoin’s price swung either up or down due to a statement or social media post by Trump, from the «Genesis» skepticism of 2019 to the naval blockades of 2026.

The Top Five BTC Price Swings

1. July 11, 2019 — The «Not a Fan» Genesis Post. In his first direct broadside against the asset class, Trump posted on Twitter: «I am not a fan of Bitcoin and other Cryptocurrencies, which are not money… and based on thin air.» Bitcoin dropped 7.1% within 45 minutes of the thread.

2. March 3, 2025 — The Strategic Reserve Pivot. Following a year of pro-crypto campaigning, Trump confirmed via Truth Social that his «Strategic National Crypto Reserve» would include a multi-asset basket of cryptocurrencies, most notably bitcoin. Bitcoin surged 8.2% in under 24 hours, jumping from $84,000 to over $91,000.

3. October 10, 2025 — The 100% tariffs on China. In yet another Truth Social post, Trump announced a 100% tariff on all Chinese imports to counter Beijing’s rare-earth export controls. Bitcoin plummeted 12.4% in roughly two hours, crashing from its $124,714 all-time high toward $102,000. And in 24 hours, a $19.38 billion liquidation event had taken place, marking the largest single-day wipeout in the asset’s history.

4. March 3, 2026 — The Anti-Bank «Genius Act» Post. Trump took to Truth Social once again to criticize Wall Street banks for «undermining» the Genius Act and delaying the passage of the Clarity Act over stablecoin yield provisions. Bitcoin rose 5.2% in 10 minutes to $71,000. This moment highlighted the administration’s willingness to go to war with the legacy financial system to protect the crypto sector.

5. April 14, 2026 — The Peace Talks. Following the naval blockade of the Strait of Hormuz, Trump said that Iran had «reached out» for potential peace talks and that a deal was «very possible.» Bitcoin rose 6.2% within 30 minutes from $70,000 to nearly $75,000.

It Might Happen Again

Bitcoin shot to a more than two-month high above $78,000 on Friday after Trump essentially announced the end of the war and the full reopening of the Strait of Hormuz. Yet, by the end of the day, there were already questions about exactly what the U.S. and Iran had agreed to.

By Saturday morning, Iran’s military said the Strait was again closed, and there were reports of some ships making U-turns and others being fired upon. Crypto prices were quickly giving back Friday’s gains, with bitcoin sliding back below $76,000.
