U.S. stocks surged to a new all-time high on Friday after Iran announced that the Strait of Hormuz, a critical global oil chokepoint, was reopened for commercial tanker traffic. The news sent oil prices tumbling back to pre-conflict levels, providing a major boost to Wall Street.

Why it matters

The Strait of Hormuz is a strategic maritime chokepoint that carries over a fifth of the world's oil supply. Its closure due to the recent Iran-US conflict had sent global energy prices soaring and raised fears of a prolonged economic crisis. The reopening of the strait is a significant de-escalation that should help stabilize global energy markets and economic growth.

The details

Iran's announcement that the Strait of Hormuz was open again for commercial tanker traffic sent U.S. crude oil futures plummeting over 5% on Friday, erasing much of the price surge seen since the start of the Iran conflict in early 2026. This provided a major boost to U.S. stocks, with the S&P 500 and Nasdaq Composite indexes both closing at new record highs.

  • The Iran-US conflict began in early 2026, leading to the closure of the Strait of Hormuz.
  • On April 18, 2026, Iran announced that the strait was reopened for commercial tanker traffic.
