Wall Street's Calm on Iran Risks May Be a Recipe for Disaster

US stocks are trading near record levels despite ongoing geopolitical tensions, particularly with Iran. The S&P 500 has reached a new high, and nearly 90% of its companies have reported quarterly results, showing aggregate earnings growth of around 30% from last year.

The strong corporate profits are helping investors look past the geopolitical risks, including the situation in the Strait of Hormuz. Investors may be assuming that the current tensions won't damage the variables that determine stock prices, such as revenue, earnings, margins, interest rates, and economic growth.

However, the market's complacency is a concern, as it may lead to a greater vulnerability to potential disruptions. The Strait of Hormuz is crucial for oil trade, with around 20% of global petroleum consumption passing through it. A sustained oil shock could have significant consequences for the US economy and markets.

The US Strategic Petroleum Reserve (SPR) has declined by around 27% since March, from 415 million barrels to 304.8 million barrels. While this is a concern, experts argue that the SPR functions as insurance, and its value increases when uncertainty rises. The real problem is not running out of oil but rather losing confidence in government intervention to control price shocks.
