What Happened?

A number of stocks fell in the afternoon session after markets reacted to President Trump's threat to "completely obliterate" Iran's energy infrastructure and the critical Kharg Island hub. 

The ultimatum raised the specter of a total energy supply shock. Notably, Kharg Island handles 90% of Iran's crude exports. The escalating rhetoric, including potential ground force deployment to seize fuel hubs, drove a flight to safety.

Zooming In On Caterpillar (CAT)

Caterpillar’s shares are not very volatile and have only had 7 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful, although it might not be something that would fundamentally change its perception of the business.

The previous big move we wrote about was 27 days ago when the stock dropped 4.5% on the news that geopolitical tensions in the Middle East sent crude oil prices soaring, stoking fears of resurgent inflation. 

The price for Brent crude, the international benchmark, leaped over 6% to $82.57 a barrel amid an escalating war with Iran, which has threatened to block the Strait of Hormuz. This critical waterway handles about 20% of global oil flow. 

A sustained increase in energy prices could translate to higher inflation, potentially impacting consumer spending and corporate earnings. This scenario also complicates the Federal Reserve's path forward, as persistent inflation could delay anticipated interest rate cuts that investors have been counting on to support the economy.

Caterpillar is up 11.5% since the beginning of the year, but at $666.96 per share, it is still trading 13.9% below its 52-week high of $775 from February 2026. Investors who bought $1,000 worth of Caterpillar’s shares 5 years ago would now be looking at an investment worth $2,862.
