S&P 500 Surges as Iran-Israel Ceasefire and Fed Flexibility Ease Market Fears

U.S. stocks closed sharply higher on Tuesday, as investors welcomed signs of geopolitical stability and comments from Federal Reserve Chair Jerome Powell that kept interest rate cuts on the table.

By the close of the market:

• Dow Jones Industrial Average rose 507 points (+1.2%)

• S&P 500 gained 1.1%

• NASDAQ Composite climbed 1.4%

Ceasefire Relief Lifts Risk Appetite

Markets were buoyed after U.S. President Donald Trump declared via social media that the Iran-Israel ceasefire is “now in effect.” This follows nearly two weeks of high-stakes military strikes between the two countries.

While skepticism remains about how long the truce will hold—especially after Trump rebuked Israel for its strong retaliatory actions—the initial easing of tensions was enough to remove some of the geopolitical risk premium baked into equities and commodities.

Crude oil prices plunged on the announcement, with traders pricing out the risk of supply disruption through the Strait of Hormuz. Use the Commodities API to track live updates on Brent and WTI futures and assess broader inflationary trends.

Powell Keeps Rate Cuts on the Table

Fed Chair Jerome Powell’s testimony before Congress was another major catalyst. His comment that "many paths are possible" was seen as leaving the door open for rate cuts—despite the Fed’s recent hawkish stance.

This dovish tilt comes after Trump-appointed Fed Governors Michelle Bowman and Christopher Waller suggested a July rate cut could be warranted if inflation stays tame despite tariff impacts.

What Does This Mean for Investors?

Investors are now weighing two powerful bullish forces:

1. Geopolitical relief — An Iran-Israel ceasefire, though fragile, removes immediate downside risk from global markets.

2. Policy flexibility — The Fed appears willing to adjust course quickly if inflation stays subdued, reinforcing a backstop for risk assets.

With Treasury yields falling and equities climbing, risk-on sentiment looks poised to continue—barring a breakdown of the ceasefire or hotter-than-expected inflation data.

Final Take

While the Iran-Israel ceasefire is still fragile and Powell offered no guarantees, the reduction in geopolitical anxiety and a dovish Fed tone have created short-term tailwinds for equities. Investors should remain watchful, especially as inflation prints and central bank commentary continue to shape expectations into the July FOMC meeting.
