Daishin Securities projects that the KOSPI index could see significant volatility based on the outcome of the November 3 US midterm elections. The firm estimates that a Democratic sweep would lead to a potential peak of 6,700 points, while a Republican sweep could drag the index lower.
Why it matters
International market volatility can impact household portfolios tied to global equity performance or foreign exchange fluctuations. These projections highlight how US political outcomes directly influence the cost of capital and investment sentiment in markets like South Korea.
Daishin Securities models show a 63% probability of a Democratic sweep in the US midterms, with KOSPI earnings per share projected to rise 34% next year. The analysis accounts for 200,000 outcome simulations and historical performance, though actual market reactions remain speculative.

The details
The firm predicts that a Democratic victory would likely stabilize US Treasury yields and the dollar, fostering a favorable environment for the KOSPI. Conversely, a Republican sweep is expected to trigger fiscal expansion, which could place downward pressure on domestic stocks and potentially increase US 10-year Treasury yields by 15-30 basis points. The analysis uses 1950 as the baseline for S&P 500 midterm trends to forecast these potential shifts in the Korean market.

Money Landscape
This forecast follows the long-standing observation that the S&P 500 has historically trended upward in every midterm election year since 1950. Analysts are now testing whether this pattern will hold in the 2026 cycle despite ongoing shifts in US fiscal and monetary policy.
Households with exposure to Korean equities should monitor how US election results influence currency values and yield stability. Discuss your international market exposure with a financial professional to determine if your portfolio remains aligned with your risk tolerance.
The takeaway
Market volatility often increases ahead of major political shifts, making this a period to review your long-term asset allocation. Ensure your household budget is prepared for potential market swings by verifying your current investment balances and speaking with a financial professional.
