How a Single Viral Tweet Triggered Stock Market Chaos
The False Report That Shook Wall Street
During a volatile morning on Wall Street, a widely followed X (formerly Twitter) account, Walter Bloomberg, amplified a false report claiming President Trump was considering a 90-day pause on controversial tariffs. Though completely unfounded, the misinformation caused immediate market turbulence—with major indices like the Dow Jones experiencing rapid swings before correcting minutes later.
Why This Volatility Matters
- Unusual Market Behavior: Unlike typical daily fluctuations, this incident represented extreme, news-driven volatility
- Widespread Impact: The false report affected traders, algorithms, and institutional investors simultaneously
- Erosion of Trust: Highlighted vulnerabilities in how unverified information spreads through financial markets
The Walter Bloomberg Phenomenon
The @DeItaone account, while unaffiliated with Bloomberg News, has gained credibility by:
- Curating headlines directly from the Bloomberg Terminal
- Providing real-time updates faster than many official news outlets
- Serving as a critical resource for professionals without Terminal access
How Financial News Travels
The Bloomberg Terminal ($24,000/year subscription) remains the gold standard for:
- Real-time market data
- Breaking news alerts
- Proprietary analytics
News often appears on the Terminal seconds before publication on mainstream platforms, making aggregator accounts invaluable for time-sensitive trading decisions.
The Domino Effect of Misinformation
On April 7, 2025, a cascade of errors unfolded:
- Fox News Interview: Misinterpreted comments from Kevin Hassett (NEC Director)
- CNBC/Reuters: Published unverified headlines based on the segment
- Walter Bloomberg: Amplified the inaccurate Reuters report to 1.2M followers
“HASSETT: TRUMP IS CONSIDERING A 90-DAY PAUSE IN TARIFFS FOR ALL COUNTRIES EXCEPT CHINA” (Deleted post from @DeItaone)
The White House rapidly debunked the claim via official channels, but not before market impacts occurred.
The Blame Game Unfolds
- Walter Bloomberg: Cited Reuters as the source (tweet)
- Reuters: Admitted error, withdrew story, and blamed CNBC
- CNBC: Acknowledged airing unconfirmed information during live reporting
The Human Element
In a rare break from its usual automated tone, Walter Bloomberg reacted with a stunned “wtf” before sharing CNBC’s correction (screenshot).
Key Takeaways for Financial Markets
- Verification Matters: Even established outlets can propagate errors
- Speed vs Accuracy: The tension between being first and being right
- Systemic Vulnerability: How social media amplifies market-moving misinformation
While professional traders likely saw the news directly on Terminals, this incident underscores how social media democratizes—and potentially distorts—access to financial information.
