It began on a Saturday. In a post on Truth Social, President Trump gave Iran a 48-hour deadline to reopen the Strait of Hormuz or risk attacks on its energy infrastructure, rather than in a trading room or a prepared statement delivered at a podium with flags behind it. The markets were shut down. Already, algorithms could read. Pricing had started by the time U.S. equity futures opened on Sunday night. The magnitude of the situation had become unavoidable by Monday morning, when the deadline was technically live and traditional markets were fully exposed. A geopolitical conflict was unfolding in real time, with oil tankers in the Gulf and portfolio managers in New York attempting to decide which way to flee.
Given the past few years, what transpired over the next two weeks was one of the most confusing periods of market behavior in recent memory. Trump declared a five-day halt to attacks on Iranian energy infrastructure on March 23. In a single session, that announcement caused oil prices to plummet by 15%, added $1.7 trillion to U.S. stocks, and momentarily raised Bitcoin above $70,000.

It seemed to be a resolution. It wasn’t. Israel, acting according to its own strategic calculations, broke the ceasefire almost immediately after Tehran denounced the pause claims as false. Almost all of the financial gains vanished in less than a week. The announcement was the only place the market had priced in peace.
As traders in Chicago and London watched that sequence play out, they began to ask more openly: was the pause a true diplomatic development, or was it timed with at least some awareness of what it would do to futures markets on a Monday morning? There is a strong circumstantial case for intentional market timing. On Saturday, when markets were closed and institutional players had time to set their positions for the weekend, the Truth Social post was released.
On a Monday, full liquidity was available to absorb the rally when the pause announcement was made. Although Goldman Sachs, JPMorgan, and the larger sell-side haven’t stated this directly—they aren’t in the business of accusing a sitting president of using trading-floor strategy—investors appear to be making their own silent judgments based on the sequencing.
The situation in Iran is more unstable due to the underlying market conditions than it might be in a more favorable setting. The S&P 500 was down 6.2% for the year and about 9% below its all-time high going into April after posting five straight losing weeks, the longest losing streak since 2022. The Nasdaq has dropped by almost 13% from its October peak.
In a single Friday session, the Magnificent Seven—the seven tech firms that together contributed significantly to the market’s gains over the previous three years—lost more than $330 billion in market capitalization: Meta fell 4%, Alphabet and Microsoft each fell 2.5%, Nvidia fell 2.2%, and Tesla, Amazon, and Oracle all fell more than 3%. In contrast, energy stocks have increased by more than 41% so far this year, a 53 percentage point difference from technology that would have seemed unrealistic to anyone writing an annual outlook in January.
Iran’s most direct and painful impact on the overall economy is through the oil channel. Approximately one-fifth of the world’s oil supply passes through the Strait of Hormuz, which has been mostly closed to tanker traffic for weeks. Throughout the crisis, the price of Brent crude has fluctuated between $103 and $112 per barrel, rising at the top of that range with each escalation headline and falling with each ceasefire rumor. At the consumer level, gas prices over $4.50 per gallon act as a regressive tax because they disproportionately affect lower-income households and deplete consumer spending power at a time when corporate margins are already being squeezed by rising input costs throughout the supply chain.
The OECD significantly increased its 2026 U.S. inflation estimate from 2.8% to 4.2%. Almost all of that revision is motivated by oil. With the 10-year Treasury yield rising to 4.44%, its highest level in eight months, it alters the Federal Reserve’s calculations in ways that the bond market has already begun pricing in.
The term that Wall Street detests the most is stagflation, which has made a comeback. The Fed has tools for controlling inflation, including painful ones, so it’s not that inflation on its own is uncontrollable. The Fed has tools for slowing growth, so it’s not necessarily disastrous on its own. However, the situation where the standard toolkit fails is stagflation, which is the particular combination of rising prices and stagnating output. Inflation is fueled by rate cuts to support growth.
The slowdown is made worse by raising rates to combat inflation. After 80 years of backtesting, Moody’s Analytics revealed that its AI-driven recession probability model hit 49%, which is one percentage point below the 50% threshold that has preceded every U.S. recession. According to chief economist Mark Zandi, it will be challenging to prevent a recession if oil prices remain high for weeks as opposed to months. 92,000 jobs had already been lost, according to the February jobs report. The GDP for the fourth quarter was revised down to 0.7% from its initial reading of 4.4% just one quarter prior. If you sit with that revision, it’s breathtaking.
The market strategy for this situation—a postponed strike as opposed to a settled dispute—is unsettling. A postponement is not a solution. By keeping oil high and the VIX, which peaked at 31.05 during the worst of the selling, in the kind of elevated territory that institutional investors associate with ongoing stress rather than transient volatility, it prolongs uncertainty.
The most obvious example of how professional money is interpreting the current situation is the sector rotation that is currently in progress: technology, consumer discretionary, and communication services are being sold, while energy, utilities, and consumer staples are being bid up. The price per ounce of gold reached a record $4,699. These are traditional fear trades, and those who engage in them are not doing so lightly.
With the March jobs report due on April 4 and the FOMC meeting set for April 28 and 29, the April 6 deadline—the extended date Trump set for possible strikes on Iranian energy infrastructure—now serves as the market’s next hard stop. It is marked in red on every trading desk calendar. It’s still unclear if any of those dates will provide clarity or just prolong the suspension that the market has been experiencing since a perfectly peaceful Saturday morning was disrupted by a Truth Social post.
