Following the Democratic Party's landslide victory in the U.S. midterm elections, the possibility of tighter data center regulations has come into focus, sending semiconductor and artificial intelligence (AI)-related stocks sharply lower and triggering a steep correction in both the Korean and U.S. stock markets. The market shock pushed the won-dollar exchange rate back into the 1,350-won range, while government bond yields fell amid expectations that U.S. fiscal expansion would be curbed. Conflicting interpretations of the election results and differing outlooks for future policies are driving repricing across financial markets. With election uncertainty now behind them, markets are facing rising policy uncertainty.

South Korea, where semiconductors account for a large share of exports and the stock market, is inevitably sensitive to changes in U.S. data center policy. Investors should also be mindful that foreign capital flows could heighten volatility in both stock prices and the exchange rate.

However, the possibility of tighter regulations should be distinguished from the adoption of actual policies. Investors should be wary of concluding that the semiconductor industry's outlook has collapsed before the scope and timing of any regulations, and their impact on corporate earnings, are known. They should be cautious both about panic selling and about chasing stocks in hopes of a short-term rebound. Investors should review their borrowing and their asset exposure to particular sectors, and respond in line with their ability to absorb losses.

Putting on a psychological seat belt does not mean holding on no matter what. It means avoiding unverified information and sensational forecasts, and acting according to principles set in advance based on corporate earnings and economic conditions.

Companies, too, should review their payment burdens, borrowing costs and foreign-currency liquidity in light of exchange-rate and interest-rate fluctuations. Rather than basing investment and financing decisions on short-term market conditions, they should plan for various scenarios and ensure they have room to respond. The government and financial authorities should closely monitor foreign exchange and funding markets, as well as trends in credit trading, while providing consistent explanations to prevent unnecessary anxiety from spreading. Market volatility cannot be eliminated, but principles can be established to prepare for its impact. What is needed now is not a hasty bet on the market's direction, but preparation to withstand the turbulence.
