U.S. Market Closing Review
On June 5th, U.S. stocks plummeted as a broad sell-off in the semiconductor sector and strong employment data sparked fears of further Fed rate hikes. The S&P 500 closed at 7,383.74, down 200.57 points (2.64%), while the Nasdaq lost over 1,121 points, recording a decline of about 4%. The Dow Jones also fell 695.15 points (1.35%) to 50,866.78, though it suffered relatively less.
The tech-heavy Nasdaq took the biggest hit, as fears of preemptive rate hikes increased discount rates for high-growth tech firms. Semiconductor and chip-related stocks faced heavy selling, and this broad sectoral rotation completely reversed the AI-driven rally from May. Trading volume was relatively high, with a market atmosphere dominated by stop-loss selling.
The market's tilted sentiment stems from the fact that strong U.S. job data has pressured the Federal Reserve to reconsider interest rate hikes. As inflation concerns revived, 10-year Treasury yields rose, followed by a stronger dollar. The closing mood was clearly bearish, with investors quickly offloading risk assets.
Macro & Economic Indicators
-
U.S. Non-Farm Payrolls: Strong job growth has led the market to reassess the possibility of Fed rate hikes, reviving inflation concerns and causing bond yields to spike.
-
Rising Treasury Yields: The 10-year U.S. Treasury yield rose in response to strong employment data, increasing rate hike expectations and putting pressure on growth stock valuations.
-
Dollar Strength: The dollar index rose due to safe-haven demand and rate hike prospects, creating headwinds for emerging market assets and commodities.
Global Top News (Market Impact)
Global Oil Supply Constraints Intensify Due to Middle East Field Closures
- What happened: With negotiations to resume tanker traffic in the Strait of Hormuz stalling, global oil inventories have dropped to dangerous levels. Warnings are emerging that persistent upward pressure on oil prices could shake financial markets within the next few weeks.
- Market Implications: A surge in oil prices directly impacts South Korea, an energy importer, leading to higher costs. Renewed inflation concerns will influence the Bank of Korea's (BOK) base rate decision. It is negatively viewed for semiconductor and shipping stocks in the short term.

Tanker Traffic Through the Strait of Hormuz Increases Via Secret Routes
- What happened: Tankers have been using concealment measures to exit the Strait of Hormuz over the past few weeks. This is releasing large amounts of oil inventory trapped in the Gulf, but a return to normal is still uncertain.
- Market Implications: While the possibility of a gradual decline in oil prices is growing, volatility is expected to remain high as long as geopolitical uncertainty persists. South Korea’s chemical and oil refining sectors should be cautious of short-term volatility.
Global Equity Weakness Deepens Amid Middle East Unrest
- What happened: Hopes for an end to the Iran-U.S. conflict have vanished, causing Middle East tensions to flare again, leading to a simultaneous rise in global equity markets and oil prices. Investor risk-aversion is intensifying.
- Market Implications: The South Korean stock market is expected to be affected by this global risk-off sentiment, with weakness anticipated in export-driven sectors like semiconductors and autos. Preference for defensive and dividend stocks is expected to be strong.

Dual Pressure from Slowing Global Growth and Rising Defense Spending
- What happened: The IMF's World Economic Outlook warns of a double whammy: slowing global growth and resurging inflation. Increased defense spending due to the Iran-Russia conflict is adding to fiscal burdens.
- Market Implications: Global economic deceleration worsens South Korea's export outlook, particularly potentially leading to reduced demand for semiconductors and electronic components. Reassessment of mid-to-long-term growth is likely.
South Korea Market Checkpoints
The sharp drop in U.S. stocks is expected to have a direct negative impact on the Korean stock market. Weakness in the semiconductor sector (Samsung Electronics, SK Hynix) is the primary concern, as the U.S. chip sell-off is linked to the Korean memory semiconductor industry. The KRW/USD exchange rate may face upward pressure due to a strong dollar, which may slightly improve export profitability but cannot offset concerns over weakened global demand.
Secondary battery-related stocks are also facing uncertainties due to concerns over sluggish global EV demand and the possibility of energy transition policy reviews caused by oil price volatility. Given the trends in overnight futures and ADRs, Samsung Electronics and SK Hynix ADRs are likely to be weak, and KOSPI may see an opening drop of over 200 points.
Watch List
- Economic Indicators/Events: European Central Bank (ECB) statements and Chinese economic data (time TBD, high market interest).
- Earnings: Check for earnings surprises (or further bad news) from major tech/semiconductor companies in the pre-market.
- Fed/Policy Events: Federal Reserve official statement release scheduled (watch for signals regarding rate hike prospects).
- Risk Factors: ① Worsening situation in the Strait of Hormuz → possibility of oil price spikes. ② Possibility of the semiconductor sector entering a further downward cycle.
Investor Action Items
-
Morning Session Response — After confirming the KOSPI downtrend immediately after opening, assess the degree of weakness in individual sectors. If semiconductor/secondary battery weakness is severe, a shift to defensive positioning is necessary.
-
Sectors/Stocks to Monitor — Keep a close eye on the supply and demand for semiconductor stocks like Samsung Electronics and SK Hynix, and the surge in volatility for energy/export stocks like HD Hyundai and HD Korea Shipbuilding & Offshore Engineering. Recognize that the benefits of rising oil prices are limited.
-
Risk Management — In this high-volatility environment, clearly set stop-loss lines and consider portfolio rebalancing to prepare for continued bond and dollar strength amid renewed rate hike concerns.
