US-Iran Tensions Send Oil Prices Soaring: Key Checkpoints Before Investing in Defense and Refinery Stocks
Amid escalating military tensions between the US and Iran, global oil prices are soaring. While foreign capital outflows drag down the KOSPI index, refinery and defense stocks are showing strong upward momentum.

Military tensions between the US and Iran are escalating rapidly, leading to a sharp contraction in global risk appetite. As a result, the KOSPI index closed lower, breaching the 2,750 mark.

Geopolitical Risks from the Middle East and Market Capital Outflow
Deepening geopolitical instability surrounding the US and Iran has cast a chill over domestic and international stock markets. In particular, a massive net selling trend by foreign investors has emerged, leading to rapid capital outflows centered on large-cap stocks. The spike in the US 10-year Treasury yield has also exacerbated valuation burdens, acting as a primary catalyst for the index's decline.
Refinery and Defense Stocks Rally Amid Oil Price Volatility
As uncertainties in traditional financial markets mount, international oil prices are wildly fluctuating due to concerns over crude oil supply disruptions. Consequently, refinery and energy-related stocks, reflecting expectations of improved refining margins, rose uniformly. Furthermore, fears of prolonged global conflicts have channeled buying pressure into defense industry stocks, forming a powerful market theme. Given the maximized market volatility, a selective approach backed by strong earnings fundamentals is essential.
