NEW YORK >> Oil prices leaped, and stocks slumped Friday on worries that escalating violence following Israel’s attack on Iranian nuclear and military targets could damage the flow of crude around the world, along with the global economy. The S&P 500 sank 1.1% and wiped out what had been a modest gain for the week. The Dow Jones Industrial Average dropped 769 points, or 1.8%, and the Nasdaq composite lost 1.3%.

The strongest action was in the oil market, where the price of a barrel of benchmark U.S. crude jumped 7.3% to $72.98. Brent crude, the international standard, rose 7% to $74.23 for a barrel.

Iran is one of the world’s major producers of oil, though sanctions by Western countries have limited its sales. If a wider war erupts, it could slow the flow of Iran’s oil to its customers and keep the price of crude and gasoline higher for everyone worldwide. Beyond the oil coming from Iran, analysts also pointed to the potential for disruptions in the Strait of Hormuz, a relatively narrow waterway off Iran’s coast. Much of the world’s oil that’s been pulled from the ground moves through it on ships.

Past attacks involving Iran and Israel have seen prices for oil spike initially, only to fall later “once it became clear that the situation was not escalating and there was no impact on oil supply,” according to Richard Joswick, head of near-term oil at S&P Global Commodity Insights.
