The Strait of Hormuz: Security Developments and Impacts on Oil, Gas, and Other Commodities

CRS (Congress) · Michael Ratner, Liana W. Rosen, Clayton Thomas ·

Executive Summary

In early 2026, U.S. and Israeli military operations against Iran led to Iranian retaliations, including efforts to control the Strait of Hormuz through attacks on commercial shipping. This significantly disrupted global oil, gas, and commodity markets, with Iran attempting to formalize its control over the vital waterway. Despite a temporary ceasefire and MOU, renewed conflict and U.S. blockades have created prolonged instability, impacting global energy prices and prompting various U.S. policy considerations.

Why It Matters

This document is crucial for defense and geopolitical analysts as it details a hypothetical near-future conflict involving Iran and the U.S. over the Strait of Hormuz, outlining potential military actions, economic impacts, and strategic implications for global energy security.

Key Takeaways

  • Iranian attempts to control the Strait of Hormuz in 2026 led to significant disruptions in global oil and gas markets, causing price volatility.
  • The U.S. and Iran engaged in military actions and diplomatic efforts (MOU) that ultimately failed to secure free passage, leading to renewed conflict and U.S. blockades.
  • Future scenarios include major U.S. military operations, negotiated settlements, or prolonged instability, all with significant implications for regional and global energy security.],

Strategic Relevance

The Strait of Hormuz is a critical chokepoint for global energy trade. Iranian attempts to control it, and the U.S. response, directly impact international shipping, energy prices, and regional stability, necessitating strategic planning for military, economic, and diplomatic interventions.
