**Oil Prices Surge as U.S. Bombs Iranian Nuclear Sites, Raising Global Supply Fears**

Oil prices **soared in early Monday trading** after the United States formally entered the conflict between **Israel and Iran**, launching strikes on **Iranian nuclear facilities**. The escalation has cast a dark cloud over the **outlook for global oil supply** and intensified fears of a broader regional crisis.

**Brent crude**, the international benchmark, surged as much as **5.7%** to **$81.40 per barrel** when markets reopened on Sunday night, while **West Texas Intermediate (WTI)** rose **3.2%** to **$76.20**.

The sharp move follows days of mounting tension, with investors now bracing for **Tehran’s response**. Among the most alarming developments: **Iran’s parliament voted on Sunday to block the Strait of Hormuz**, a vital shipping route for around 20% of global oil. Although not yet final, such a move would be **deeply inflationary and severely disrupt supply chains**.

Oil had already been climbing, having gained roughly **10%** since Israel launched strikes on Iranian energy infrastructure **ten days ago**. On Friday, Brent closed at around **$77 a barrel**.

### Market Reaction

-
**Stock futures** turned lower ahead of Monday’s open, with the **Dow Jones Industrial Average** and **S&P 500** both down **0.4%**.

-
In Asia:

**Hong Kong’s Hang Seng** slipped **0.5%**

-
**Tokyo’s Nikkei** was broadly flat

-
**Australia’s S&P/ASX 200** eased **0.2%**

### Flight to Safety

Geopolitical risk also triggered a shift to **safe-haven assets**:

-
**Spot gold** climbed **0.4%** to **$3,380.72 per ounce**, reflecting rising demand for defensive plays amid global uncertainty.

Markets are now closely watching **Iran’s next move** and any further signals from Washington, with the potential for **major energy shocks** and renewed **volatility across asset classes**.
