Major US Indexes Skyrocket on De-escalation Hopes

US stock markets experienced a significant rally on Tuesday, driven by emerging reports suggesting a possible conclusion to the ongoing conflict involving the US and Iran. All three primary US indexes surged more than 2%, reflecting strong investor optimism.

The initial upward momentum began after The Wall Street Journal published news that President Trump was considering ending the conflict, even without securing the reopening of the critical Strait of Hormuz.

Trump Signals Withdrawal and Strait Reopening

These gains were further amplified by direct comments from President Trump to the New York Post. Trump stated that the US would not remain involved in the region for an extended period.

He explicitly linked the reopening of the Strait of Hormuz to the eventual withdrawal of US forces. This provided a clear pathway for market relief.

Unconfirmed Iranian Reports Fuel Afternoon Surge

Trading volumes swelled even more significantly during afternoon sessions. This was fueled by unconfirmed reports indicating that Iranian President Masoud Pezeshkian was amenable to concluding the war.

While this surge offered a positive end to a challenging month for equities, it is important to note that US indexes remain substantially lower since the conflict initially began.

Market Performance Snapshot (Around 2 p.m. ET)

The market reaction showed broad strength across key benchmarks:

  • S&P 500: Reached 6,496.48, marking a 2.4% increase.
  • Dow Jones Industrial Average: Climbed to 46,171.48, up 2.1%.
  • Nasdaq Composite: Led the gains, rising 3.3% to 21,479.61.

Impact on Commodities and Treasury Yields

Divergent Oil Price Movements

The reaction in the energy sector was mixed following the de-escalation headlines. West Texas Intermediate (WTI) crude oil prices dropped as much as 3% on the positive news.

Conversely, Brent crude continued its upward trajectory, climbing 5% and moving closer to the $120 per barrel mark.

Treasury Yields Decline

The yield on the 10-year US Treasury note decreased by four basis points, settling at 4.3%. Yields had previously spiked as the conflict reached its one-month milestone, reflecting expectations of inflation and higher interest rates stemming from Middle East instability.

Analyst Caution Amid Market Optimism

Institutional Rebalancing Factor

Marko Kolanovic, the former quant chief at JPMorgan, pointed out that the stock market rise coincides with month-end rebalancing activities undertaken by institutional pension funds.

Kolanovic also noted that the news regarding President Pezeshkian’s openness to ending the war was not entirely new. The Iranian president had previously indicated willingness, provided certain guarantees were met.

Skepticism Over Iranian Authority

Adam Cochran, a policy consultant and venture fund investor, expressed caution regarding the market's enthusiasm. He warned that President Pezeshkian might not hold the ultimate decision-making power within Iran's current government structure.

Cochran further highlighted historical context, noting that previous signals from Iran ready for a deal included control over the Strait of Hormuz, which the US views as essentially non-negotiable.
