Global Market: US-Iran Tensions Lift Brent Above $90 as Kospi Declines 3% and GIFT Nifty Weakens

Global market sentiment turned sharply risk-off on July 20, 2026. Brent crude broke above $90 a barrel as US-Iran hostilities entered a ninth consecutive night. South Korea’s Kospi tumbled into a technical bear market. India’s GIFT Nifty pointed to a weak open. The common thread across every market: fear over the Strait of Hormuz and its impact on global energy flows.

Brent Crude Surges Past $90 as Iran Conflict Escalates

Brent crude for September delivery rose about 2.77% to top $90 a barrel on Monday. WTI crude for August delivery climbed roughly 2.4% to $84.49. The US confirmed a third American service member killed in the conflict.

• US Central Command completed its ninth straight night of strikes on Iranian targets.
• Washington reinstated a naval blockade near Iranian ports close to the Strait of Hormuz.
• Iran has threatened to disrupt Red Sea shipping through Houthi forces.

Quantum Strategy’s David Roche said crude inventories could tighten sharply by September. He set a Brent target of $95 to $105 a barrel if hostilities persist.

Why the Strait of Hormuz Matters to Every Market

The Strait of Hormuz carries roughly a fifth of global oil supply daily. Any disruption there ripples through every energy-linked market worldwide. Commercial tanker traffic has already thinned considerably in recent sessions.

• Brent has risen more than 19% since the ceasefire collapsed in June.
• Oil-import-heavy economies like India and South Korea face the sharpest cost pressure.

Rising freight insurance and rerouting costs are adding further strain on shippers.

Kospi Slides Into Bear Market Territory

South Korea’s Kospi opened at 6,643.58, down 2.60% from Friday’s close. The index briefly slid as low as 6,498 points, a 4.52% intraday drop. That put the Kospi more than 25% below its June peak, confirming a technical bear market. Later trading pared some losses, with the index near 6,785, down about 0.5% to 1.3% depending on the session snapshot.

Kiwoom Securities analyst Han Ji-young said the Kospi has fallen roughly 25% since July began. He noted leading names have dropped 30-40% from their highs, though earnings remain solid.

Chipmakers and Autos Lead the Selloff

Samsung Electronics and SK Hynix both opened down more than 5% before foreign buyers stepped in. Samsung Electronics later settled down 1.37% at 251,500 won. SK Hynix eased 0.98% to 1.824 million won.

• Hyundai Motor fell around 4%.
• LG Energy Solution dropped 2.54%.
• Hanwha Aerospace declined 3.92%.
• Samsung Life Insurance slid 6.80%.

The Kosdaq also fell, trading near 779, down about 1.6% on the day. Chinese AI competition added further pressure on the memory chip trade.

GIFT Nifty Weakens Ahead of India Market Open

GIFT Nifty traded at 24,300.5, down 0.42% from the previous close of 24,404. The contract touched an intraday high of 24,373.5 and a low of 24,279.5, signaling a soft opening for the Nifty 50.

• Wall Street extended Friday’s decline on AI-linked stock weakness.
• Rising Middle East risk continued clouding the global energy outlook.

Dr VK Vijayakumar of Geojit Investments pointed to a positive shift in foreign portfolio flows since early July. He linked it to improving Indian macro data and rupee stability. The Nifty 50 and Sensex found support near their 20-day moving averages last week, around 24,000 and 77,000 respectively, before a modest Friday rebound.

Meyka Analyst Feedback

Every major market today is pricing the same risk: a wider Gulf conflict choking energy supply. Brent’s move past $90 confirms traders expect further escalation, not de-escalation. Kospi’s bear market signals chip-sector fatigue compounding geopolitical stress. GIFT Nifty’s soft tone suggests Indian equities will open cautiously rather than confidently. 

Analysts largely agree the next flashpoint is the Strait of Hormuz itself; any confirmed disruption there would likely push Brent well past Roche’s $95-$105 target and deepen losses across Asian and Indian market benchmarks alike.
