Let’s get started 👇

1. US–Iran Tensions Over Strait of Hormuz

The situation between the U.S. and Iran has become tense again. The U.S. hinted at negotiations, but Iran has blocked ship movement through the Strait of Hormuz.

Why it matters:

• Around 20% of global oil trade passes through this route

• Important for India’s energy security

• Can impact inflation and economy

🧠 Memory Trick:

👉 “Hormuz = Heart of Oil Flow”

This drop is linked to global instability, especially in West Asia.

Key Points:
