A familiar pattern appears to be playing out on Wall Street—sharp market declines followed by a sudden policy pivot from the White House. Within minutes of U.S. markets closing on Thursday, Trump announced a 10-day “pause,” triggering a swift rebound in futures and raising fresh questions about whether markets are beginning to anticipate such reversals.
Markets tumble before surprise pivot
The Nasdaq tumbled more than 2% on Thursday, confirming a correction, while the S&P 500 and the Dow fell more than 1%. Investors scrambled for safety on fears of escalation in the U.S.-Israeli war against Iran, which has sent oil prices soaring and exacerbated inflation concerns.
The sell-off marked one of the sharpest declines since the beginning of the ongoing conflict, driven largely by surging oil prices and fears of prolonged instability. Energy shocks, analysts say, are now weighing more heavily on markets than earlier tariff-related disruptions.
A 10-day pause—and immediate market reaction
Shortly after markets closed, Trump announced a 10-day pause, a move that caught investors off guard. Futures reacted almost instantly, turning higher and reversing part of the day’s losses.
US President Donald Trump said Washington would pause strikes on Iranian energy facilities for another 10 days, signalling space for diplomacy even as fighting continues across the region. The announcement came in a post on Truth Social, where Trump said the extension followed a request from Tehran and confirmed the pause would run until April 6. “As per Iranian Government request… I am pausing the period of Energy Plant destruction by 10 Days… Talks are ongoing… they are going very well,” he wrote.
However, the announcement was not without controversy. Iran denied claims that it had sought a pause in strikes—contradicting Trump’s earlier assertion on social media. The conflicting narratives have added another layer of uncertainty to an already volatile geopolitical backdrop.
The “TACO” pattern: Markets and policy reversals
The episode has revived chatter around what some market participants informally describe as the “TACO” trade—a pattern where tough policy rhetoric or escalation is followed by a pullback once markets react negatively.
According to reports cited by Axios, there is a growing belief on Wall Street that Trump may recalibrate policy if equity markets fall by around 5% from their recent highs. Jose Torres noted that such behaviour has become part of market expectations, effectively creating a feedback loop between policy signals and market movements.
This perceived correlation between weak economic signals or market stress and subsequent policy softening has not gone unnoticed by investors. Increasingly, traders are factoring in the likelihood of intervention when volatility spikes.
Energy shock vs tariff turmoil
Axios’s Emily Peck told CNN that the current phase of volatility may be more damaging than earlier tariff-related disruptions. The reason: energy markets. Rising oil prices not only fuel inflation concerns but also directly impact corporate margins and consumer spending.
Unlike tariffs, which tend to have a more gradual and sector-specific effect, energy shocks ripple quickly across the entire economy. This amplifies market reactions and raises the stakes for policymakers.
What it means for markets
The latest episode underscores how tightly intertwined geopolitics, policy signals, and market movements have become. Investors are navigating not just economic data, but also the timing and credibility of political announcements.
If markets continue to respond sharply to geopolitical developments, and policymakers in turn respond to market stress, this dynamic could reinforce short-term volatility. For now, traders appear to be watching not just the headlines—but also the pattern behind them.
