Hello, this is Daily Stock. Today, we will examine the current status and future scenarios of Korean platform and large tech stocks amid the sharp rise in the USD/KRW exchange rate and the U.S. 10-year Treasury yield tantrum.

Core Summary
With continuous upward pressure on the U.S. 10-year Treasury yield pushing up the discount rate for future value, the valuations of domestic growth stocks, including internet platforms, are facing a severe test.
Combined with an extremely strong dollar environment at 1,516.50 KRW per USD, the outflow of foreign passive funds fearing foreign exchange losses is maximizing the volatility of KOSPI large-cap tech stocks.
Current Situation Summary
As of the market close on April 2, 2026, the KOSPI recorded 5,234.05 and the KOSDAQ stood at 1,056.34. The NASDAQ also closed at 21,840.95, putting the overall global stock market under significant pressure.
In particular, the USD/KRW exchange rate soared to 1,516.50 KRW on the day, stimulating foreign investors' selling sentiment, while rising import prices caused by the high exchange rate are weighing down the domestic market.
According to Daily Stock's proprietary Fear & Greed Index, the KOSPI is currently in a state of 'Extreme Fear' (18.1), showing a sharp cooling of investor sentiment from 'Neutral' (40.3) one month ago.
The NASDAQ Fear & Greed Index also remains in the 'Extreme Fear' (15.9) territory, suggesting that global bond yield volatility has strongly dampened risk appetite in the stock market.

Financial Analysis
When the U.S. 10-year Treasury yield rises, global financing costs jump in tandem, exacerbating the financial burden on large tech stocks that must continue massive AI infrastructure investments and cloud R&D.
Major KOSPI internet platform companies, including NAVER and Kakao, are forced to execute continuous capital expenditures (CAPEX) to expand new data centers and upgrade foundation models.
Such a high-interest-rate environment can undermine corporate-wide operating margins by raising interest expenses on new investment funds, ultimately carrying the risk of a slowdown in short-term free cash flow (FCF).
Valuation
Because growth assets like platforms reflect massive future profits discounted to their present value in their stock prices, as the risk-free 10-year Treasury yield rises, the discount rate increases, structurally lowering target prices.
Furthermore, as the won's value plummets to the 1,516 KRW level, foreign investors face a significantly compromised dollar-converted return even if the KRW stock price remains unchanged. Consequently, their expected return threshold for domestic tech stocks inevitably rises.
| Category | Valuation Impact of U.S. 10-Year Yield Rise | Supply/Demand Impact of 1,516 KRW Exchange Rate Environment |
|---|---|---|
| **KOSPI Platform Stocks (NAVER/Kakao, etc.)** | Surge in discount rate for future earnings (Downward pressure on PER) | Deepening outflow of foreign passive funds due to FX loss fears |
| **KOSPI Value/High-Dividend Stocks** | Concerns over reduced relative dividend appeal, but defensive strength remains valid compared to growth stocks | Low PBR appeal may be highlighted, but overall foreign buying momentum weakens |
| **KOSPI IT Manufacturing (Semiconductors, etc.)** | Pre-reflection of concerns over slowing downstream IT infrastructure demand | Limited positive effect on export unit price defense due to weak won |
Expert & Institutional Analysis
Major securities firms and institutional investors analyze that the current yield tantrum and the exchange rate surging to the 1,500 KRW level constitute a harsh 'stress test' phase testing the short-term downside support of tech stocks.
Some argue that stock prices have already entered oversold territory as disappointment selling pours out due to monetary policy uncertainty. However, this is tightly countered by cautious views that there will only be limited technical rebounds until macro imbalances are resolved.
Ultimately, the prevailing analysis is that a meaningful downward stabilization of the U.S. 10-year Treasury yield and an easing of the strong dollar trend must precede any structural trend reversal for KOSPI platform stocks.

Risk Factors
The biggest risk factor is a scenario where the high-interest-rate environment prolongs much longer than the market initially expected, driven by an inflation rebound such as rising oil prices due to global geopolitical tensions.
If the USD/KRW exchange rate becomes entrenched above 1,516 KRW, domestic companies' imported raw material and infrastructure construction costs could skyrocket, potentially triggering a vicious cycle of sluggish domestic demand and slowing platform advertising revenue.
Investment Perspective Summary
Currently, the KOSPI level of 5,234.05 and the Extreme Fear Index (18.1) suggest that panic selling and uncertainty have largely been priced into the market. However, rather than making hasty bottom predictions, it seems wiser to directly confirm the stabilization of macroeconomic indicators.
Therefore, when approaching platforms and large growth stocks with high interest-rate sensitivity, it may be advantageous to strictly limit leverage, maintain a sufficient cash proportion, and adopt a strategy of split purchasing after verifying a trend reversal in the exchange rate.
Q&A with Daily Stock
1. Why is the U.S. 10-year Treasury yield fatal to tech stocks?
Because the U.S. 10-year Treasury yield is the benchmark for long-term financing and the key metric for discounting future earnings, a rise in this rate mathematically lowers the present value of platform and IT companies that rely heavily on distant future growth rather than immediate profits.
2. What is the impact of a 1,516 KRW exchange rate on platform stock prices?
When the exchange rate jumps well past the 1,500 KRW mark, foreign investors suffer massive dollar-based losses due to foreign exchange losses just by holding Korean stocks. This triggers mechanical outflows, acting as strong downward pressure on large platform stocks highly dependent on supply and demand.
3. The current KOSPI Fear & Greed Index is at 18.1 ('Extreme Fear'). Should this be viewed as a buying opportunity?
Statistically, a state of extreme fear is a phase with a high probability of a short-term technical rebound. However, in a phase like the present where fundamental macro risks such as interest and exchange rates remain unresolved, it may be safer to prioritize risk management rather than blindly trusting it as a structural bottom.
4. When will suppressed large platform tech stocks be able to relieve their valuation burden?
When the U.S. Federal Reserve's monetary policy uncertainty clears up and inflation concerns subside, allowing the 10-year Treasury yield to transition into a clear downward trend, tech stocks are highly likely to shed their discount rate burden and begin receiving fair valuations relative to their performance again.
5. What risk management should general investors practice in a high exchange rate and high interest rate phase?
In times of extreme volatility in macroeconomic indicators, the most important thing is to avoid buying on margin (investing with borrowed money) and to appropriately secure cash in your portfolio, building the account's resilience to flexibly respond when unexpected shocks occur.
