Iran Considers Closing Strait of Hormuz: Will Global Oil Prices Surpass $100? Market Impact Analysis

Global oil prices are experiencing a steep upward trend following reports that Iran is considering restricting transit through the Strait of Hormuz, a crucial chokepoint through which approximately 20% of the world's oil supply passes. As geopolitical risks in the Middle East reach a climax, direct shocks are being felt across global energy markets and stock exchanges.

Background of the Strait of Hormuz Crisis and Surging Energy Prices

Amid extreme military tensions in the Middle East, Iran has hinted at the possibility of weaponizing the Strait of Hormuz, a major oil transport route. This strait is a strategic hub for major oil-producing countries like Saudi Arabia, Kuwait, and Iraq, with an average of 21 million barrels of crude oil passing through it daily.

Upon this news, both Brent crude and WTI (West Texas Intermediate) prices spiked in the short term, expanding market volatility. Market experts warn that if a blockade becomes reality, global oil prices could easily surpass $100 per barrel, potentially reigniting global inflation.

Impact on Domestic and International Stock Markets and Exchange Rates

The surge in oil prices and geopolitical anxiety are heavily stimulating a 'safe-haven preference' across the entire global financial market.

• Acceleration of Foreign Capital Outflow: In the KOSPI market, the combination of Middle East risks and the US employment shock has triggered massive foreign net selling, driving the index down.

Increased Volatility in KRW/USD Exchange Rate: The exchange rate, which had been falling due to expectations of a US rate cut in September, may face upward pressure again due to concerns over a worsening trade balance stemming from surging energy imports.

Short-term concentration in Oil Refining and Defense Stocks: Despite overall market weakness, energy-related stocks like S-Oil and defense stocks like Hanwha Aerospace are attracting attention as short-term safe havens, increasing their volatility.

FAQ: Key Questions Regarding Middle East Risks

Q1. Is there a possibility of a complete blockade of the Strait of Hormuz?

The prevailing view is that a full blockade is unlikely as it would be a fatal blow to Iran's own economy. However, even limited measures such as 'enhanced transit inspections' or 'localized seizures' will add a massive uncertainty premium to oil prices.

Q2. Will surging oil prices affect the Fed's potential September rate cut?

A spike in energy prices directly drives up the Consumer Price Index (CPI), complicating the Federal Reserve's calculations. While a rate cut in September is highly likely due to the current employment slowdown signals, growing fears of reignited inflation could dampen expectations for a 'Big Cut' (0.5%p reduction).

Q3. How should investors respond in this situation?

Geopolitical risks are inherently unpredictable in the short term. It is necessary to refrain from aggressively increasing stock allocations or chasing thematic stocks prematurely, and instead adopt a conservative approach by reviewing safe asset holdings like gold or the US dollar while monitoring the situation.
