Semiconductor Plunge and Oil Price Surge Amid Seoul Rent Crisis and Subscription Controversies — July 18, 2026 Afternoon Market Report

📊 Market Overview

As of the afternoon of July 18, 2026, asset markets are experiencing extreme mixed momentum. While stock markets have plunged due to concerns over the global semiconductor sector peaking, cryptocurrencies have shown a recovery trend driven by favorable U.S. inflation data. Simultaneously, market volatility is significantly expanding due to soaring rent prices in Seoul apartments and a massive spike in international oil prices stemming from Middle East risks.

🏠 Real Estate Market

Recently, the housing market is showing signs of renewed rent crisis concerns, with fears of side effects from the 'Three Lease Laws' and Seoul apartment rent prices rising by 1.3% in a single month. The increase in the jeonse (rent) to purchase price ratio could stimulate gap-investment demand, acting as upward pressure on purchase prices, creating high market vigilance.

In the subscription market, news of a famous celebrity winning a 'lottery-like' subscription has ignited dissatisfaction regarding the fairness and effectiveness of the price ceiling system. The controversy over 'wealth inheritance'—where only cash-rich individuals benefit—is growing fiercely, deepening a sense of relative deprivation among the younger generation.

Consequently, all eyes are on the 'Special Real Estate Debate' presided over by the President, scheduled for the 23rd. While the market watches to see if breakthrough housing stabilization measures will emerge, there is also strong skepticism about whether current supply-demand imbalances and speculative sentiment can be quelled in the short term.

📈 Stock Market

The domestic stock market directly absorbed the shock of the simultaneous slump in the global semiconductor sector. KOSPI plummeted by over 8% compared to the previous week, closing at the 6,820 level, driven by intense selling pressure centered on large-cap semiconductor stocks. With significant drops in major semiconductor-related stocks including Samsung Electronics, investor sentiment has frozen solid. KOSDAQ is also continuing its weak trend, showing 'asymmetric flow' due to the deepening concentration of funds into KOSPI large caps. Market regulations have also tightened, such as raising the basic deposit requirement for single-stock leveraged ETFs amid volatility concerns.

U.S. stock markets also saw massive profit-taking in large tech stocks as doubts grew over the profitability of AI companies. Notably, the Philadelphia Semiconductor Index plummeted over 18% for the month, officially entering a bear market. Conversely, the Dow Jones Industrial Average showed relatively strong defensive capabilities, limiting its index decline. In individual stocks, Netflix dropped over 8% due to concerns over slowing subscriber growth, and Intuitive Surgical experienced a double-digit percentage plunge following poor earnings.

₿ Cryptocurrency Market

Unlike the sluggish stock market, the cryptocurrency market is showing signs of recovery. Bitcoin (BTC) recouped its losses and recovered the $64,000 mark as U.S. consumer price index (CPI) data showed favorable trends. Although it experienced a temporary drop due to escalating geopolitical tensions in the Middle East, it quickly secured support levels.

Ethereum (ETH) is also maintaining strength compared to other assets, but internal indicators such as on-chain data show a somewhat mixed picture. A notable point is that net inflows have resumed into Bitcoin and Ethereum spot ETFs, which had seen continuous outflows for a while. Major brokerage E-Trade has begun supporting Bitcoin and Ethereum trading, accelerating institutional adoption. However, the market's 'Fear and Greed Index' remains in an extreme fear zone, with trading volume plummeting by 24%, indicating a strong wait-and-see attitude.

💱 FX, Rates & Commodities

In the FX and commodities markets, macroeconomic indicators and geopolitical variables are clashing. The Dollar Index (DXY) is trending sideways at 100.784, while the slowdown in U.S. inflation data raises expectations for future Federal Reserve rate cuts.

However, the most prominent volatility occurred in the commodities market. With war clouds gathering in the Middle East, international oil prices skyrocketed by an unprecedented 14% in the short term. This is a fatal variable that could throw cold water on inflation stabilization, adding significant uncertainty to the future interest rate path.

🔍 Comprehensive AI Analysis

The current global asset market is complexly intertwined with expectations for inflation stabilization, geopolitical crises, and concerns about a peak in a core industry (semiconductors). The slowdown in U.S. CPI served as a catalyst for Bitcoin's rebound, but the oil price spike from Middle East risks is spawning fears of re-igniting inflation.

The real estate market is in a situation where rent instability stimulates buying sentiment amidst policy uncertainty. For the time being, investors should step back from aggressive investments centered on tech stocks and focus on portfolio diversification and risk management in preparation for a volatile market. In particular, U.S. big tech earnings scheduled to be announced next week and the outcome of the domestic real estate debate will act as key triggers determining the market's short-term direction.

❓ FAQ

• Q. With semiconductor stocks crashing, is it a good time to buy?
  A. Currently, caution regarding the global sector peak is very high, with the Philadelphia Semiconductor Index entering a bear market. While a technical rebound is possible, it is advantageous to approach conservatively after confirming major big tech earnings announcements.
• Q. What is the impact of skyrocketing oil prices on asset markets?
  A. A surge in oil prices re-stimulates the global inflation that had been cooling down, limiting central banks' room to cut interest rates. This acts as a negative factor for stocks and can relatively affect safe assets or the value of the dollar.
• Q. Will the upward trend in Seoul rent prices continue?
  A. Combined with structural factors like the Three Lease Laws and a lack of new supply, anxiety in the rent market is highly likely to continue for a while. The upcoming government real estate policy announcement could be an inflection point, so policy changes should be closely monitored.
