[R&E: Research & Epoch]

Global Market Brief

The New York stock market closed mixed the previous day. The Dow Jones Industrial Average (NYSE: DJI) fell 0.13% to 46,504.67p, but the S&P 500 (NYSE: SPX) index rose 0.11% to 6,582.69p, and the NASDAQ Composite (NASDAQ: IXIC) gained 0.18% to 21,879.18p, with tech-driven strength partially supporting the market. However, analysis suggests this is merely a relative strength amid the spreading instability in the commodities market and falls short of indicating the overall market direction.

The key variable is oil prices. West Texas Intermediate (WTI) crude surged 11.41% from the previous day to $111.54, and the Brent crude spot price reached $141 per barrel, breaking the highest level since the 2008 financial crisis. The increase in oil prices for the month of March alone exceeds 60%. This is the result of geopolitical risks maximizing supply instability as the Strait of Hormuz was effectively closed due to the escalating war in Iran. The US administration diagnosed that it is facing a liquidity risk of more than 600 million barrels due to this situation.

The surge in energy prices exacerbates global inflation pressure and pushes up corporate production costs. Indeed, the fact that Amazon (NASDAQ: AMZN) has started imposing an additional 3.5% fuel and logistics surcharge on third-party sellers in North America suggests an adverse impact on future corporate earnings. The US 10-year Treasury yield fell slightly to 4.305%, seemingly finding stability, but the dollar index rose to 100.03pt, further solidifying the strong dollar trend. This is because rising oil prices are increasing inflationary pressure and stimulating preference for safe assets.

Domestic Market Overview

On the previous trading day, the domestic stock market plunged, unable to withstand the double whammy of soaring oil prices and an intensifying strong dollar. The KOSPI plummeted 4.47% from the previous day to 5,234.05pt, and the KOSDAQ dropped 5.36% to 1,056.34pt, inflicting deep wounds on both markets. Unlike the mixed trend in the New York stock market, the Korean stock market reacted exceptionally sensitively, exposing a structure vulnerable to macroeconomic variables.

The KRW/USD exchange rate recorded 1,519.70 won in the Seoul foreign exchange market and continued a steep upward trend, breaking the 1,510 won mark in the Non-Deliverable Forward (NDF) market as well. It is judged that concerns over a worsening trade balance due to soaring oil prices and a contraction in foreign investor sentiment triggered the rise in the exchange rate. Korea Treasury yields also surged for both the 10-year (3.808%, +11.8bp) and 3-year (3.479%, +10.9bp) bonds. As market fear transfers to the bond market, the possibility of liquidity contraction is heightening.

Key Industry Issues and Insights

Price spikes in the energy market may boost the profitability of the refining industry in the short term, but they act as a negative factor for the overall industry in the form of increased production costs and logistics burdens. In particular, mounting inflation pressure is highly likely to trigger a vicious cycle of contracting consumption and economic slowdown by increasing the central bank's burden of monetary tightening.

Even amidst such uncertainty, the semiconductor industry demonstrated unrivaled resilience in recovery. Samsung Electronics's operating profit for the first quarter of 2026 is estimated at 53.9 trillion won, and it is expected to break its all-time high by recording 50.3 trillion won in the memory division alone. DRAM and NAND selling prices surged 87% and 79%, respectively, driving a strong industry recovery. With the Philadelphia Semiconductor Index rising the previous day, expectations for earnings improvement based on AI demand remain valid, as seen with Intel (NASDAQ: INTC) rising 4.89% and AMD (NASDAQ: AMD) climbing 3.47%.

In the construction sector, DL E&C is expected to record an operating profit of 126.6 billion won, exceeding market expectations. Along with solid revenue growth in the housing division, the NASDAQ listing momentum of its nuclear power generation subsidiary, X-Energy (NASDAQ: XE), is a key driver for the re-evaluation of its corporate value. This suggests how important revenue diversification through new businesses is even amid an industry slump. Meanwhile, the rebound in China's steel PMI (50.6) has the potential to secure downside rigidity in the raw materials market through a recovery in infrastructure investment.

In the healthcare sector, the battle for leadership in the obesity treatment market is fierce. Novo Nordisk (NYSE: NVO)'s oral Wegovy gained an edge in a comparative trial against Eli Lilly (NYSE: LLY), raising the level of technological competition. Changes in market position based on clinical results are expected to be a key factor amplifying the volatility of these stocks.

Market Signals

• Deepening Domestic Stock Market Decline: KOSPI plunged to 5,234.05pt (-4.47%), KOSDAQ to 1,056.34pt (-5.36%).

• Simultaneous Surge in Bond Yields: 10-year Korea Treasury yield at 3.808% (+11.8bp), spreading market anxiety.

• Energy Prices Out of Control: WTI surged 11.41%, Brent crude breached the $141 mark, increasing inflation pressure.

• Exchange Rate Maginot Line Collapses: KRW/USD exchange rate broke 1,510 won, entrenching the strong dollar trend.

• Solid Semiconductor Fundamentals: Samsung Electronics's memory operating profit is highly likely to hit an all-time high of 50.3 trillion won.

Epoch View: Investment Implications

The supply shock in the global energy market and the resulting waves of inflation and strong dollar have emerged as the core risks in the financial market. The drop in the domestic stock market and the surge in bond yields project the market's extreme fear of macroeconomic uncertainty. However, even amid such downward pressure, the intrinsic value of industries holding overwhelming earnings prospects, like Samsung Electronics, is highly likely to be re-evaluated. Ultimately, the market's attention is expected to converge on companies that have secured cost efficiency and independent growth engines capable of overcoming the volatility of oil prices and exchange rates.
