[Deep Dive] Capital Flows and Dividend Stock Re-rating in the 2026 Market Post-FIIT Repeal

Post-Financial Investment Income Tax: Capital Flows in the 2026 Korean Stock Market

Following the repeal of the Financial Investment Income Tax (FIIT) bill in late 2024, the Korean stock market in 2026 is adjusting to a restructured tax environment. The initial push for abolition was largely driven by retail investor opposition and concerns over potential capital flight. While the systemic risk of FIIT implementation has been removed, the subsequent policy adjustments are exerting complex effects on market dynamics.

Reversal of Securities Transaction Tax and Trading Volume Shifts

To offset the expected tax revenue shortfall from the FIIT repeal, the securities transaction tax was increased. Effective January 2026, the transaction tax for sell orders on both the KOSPI and KOSDAQ markets has been adjusted upward by 0.05 percentage points from previously reduced levels. This increment elevates the cost basis for high-frequency and short-term trading strategies, acting as a moderating factor on the growth rate of average daily trading volumes.

Conversely, the retention of capital gains tax exemptions for general retail investors—excluding major shareholders holding over KRW 1 billion per stock—has successfully anchored long-term capital focused on blue-chip equities.

Separate Taxation on Dividend Income and Value Stock Re-rating

A pivotal component of the 2026 tax framework is the implementation of separate taxation on dividend income for 'high-dividend listed corporations.' By allowing qualifying dividend income to bypass aggregation with comprehensive global income, this policy has catalyzed the inflow of high-net-worth capital into dividend-yielding equities.

• Strength in Financial and Telecom Sectors: Major financial holding companies and telecommunication firms, characterized by stable cash flows and increasing shareholder return ratios, are direct beneficiaries of this tax incentive.
• Synergy with Corporate Value-up Programs: Coupled with ongoing government initiatives to enhance corporate valuations, companies announcing expanded dividend policies are experiencing accelerated re-rating cycles.

Foreign Capital Trends and Outlook

The repeal of FIIT has partially alleviated 'Korea Discount' concerns among domestic retail investors regarding tax unpredictability. However, foreign capital flows remain predominantly dictated by global macroeconomic indicators and central bank monetary policies. As of the first half of 2026, foreign institutional investors view the reduced tax uncertainty favorably but continue to prioritize the fundamental earnings performance of export-driven sectors, particularly semiconductors and automotive.

Consequently, the 2026 Korean equity market is transitioning from a high-turnover, thematic trading environment toward a structure prioritizing long-term value investing and dividend capture strategies designed to maximize the current tax benefits.
