Iranian parliament approves closure of Strait of Hormuz.

Iran’s parliament voted on June 22–23, 2025, to authorize the closure of the Strait of Hormuz, but full implementation requires approval from the Supreme National Security Council—the ultimate decision‑making body .

🔍 Why this matters

Global oil & gas chokepoint: About 20 million barrels of crude and nearly a fifth of global LNG flow daily pass through the strait .

Market impact: Oil prices have already surged ~10%. Analysts at Goldman Sachs say Brent crude could rise above $100–$150/barrel if a closure occurs .

International stakes: Any closure would threaten Iran’s own exports, alienate Gulf Arab states, hit major importers (China, India, Japan, SK), and invite a possible US-led military response .

🧭 How a closure might happen

Iran could deploy naval mines, use fast patrol boats, missiles, drones, or even seize ships in the strait—similar tactics used during the Iran‑Iraq “Tanker War” in the 1980s .

⚖️ Political signaling vs. real action

Experts believe this is mostly strategic posturing, aimed at deterrence rather than actual action. Iran’s military is weakened, and any real blockade would likely provoke swift counteraction by the US Fifth Fleet and allies .

🌍 Consequences & next steps

Aspect Implication

Energy markets Oil price spikes → inflation, increased fuel costs globally
Geopolitics Possible military skirmishes, heightened regional risk
Diplomacy US urging China to apply pressure on Tehran

The coming days are critical—the Supreme Council must now decide whether to escalate or hold back. Meanwhile, military forces from the US and regional navies are on heightened alert.
