Summary
South Korea has officially launched 24-hour trading for the Korean won, with the currency edging higher against the dollar on its first day. Concurrently, the government plans to establish a future response fund using tax revenues from the semiconductor boom to invest in AI, advanced manufacturing, and support for younger generations.
Dual Reforms in Financial Markets and Industrial Policy
South Korea's financial and economic landscape is undergoing two major transformations. On July 5, the country officially launched 24-hour trading for the Korean won, with the currency edging higher against the U.S. dollar on its inaugural day. This marks a substantive step toward modernizing the nation's foreign exchange market infrastructure. Simultaneously, the government announced plans to establish a future response fund that would channel tax revenues from the semiconductor industry's unprecedented surge into strategic areas such as AI and advanced manufacturing.
These twin initiatives reflect South Korea's strategic positioning in the global AI chip race: enhancing capital flow efficiency through financial market reform while converting industrial prosperity into long-term competitiveness investments, all while addressing growing intergenerational economic inequality.
Unprecedented Scale of Semiconductor Tax Revenues
The fiscal foundation for South Korea's future response fund stems from an explosive growth in the semiconductor sector. According to the Korea Times, the combined operating profits of Samsung Electronics and SK Hynix are projected to exceed 600 trillion won (approximately $430 billion) this year, up from roughly 90 trillion won last year—a near-sixfold increase. This surge is primarily driven by soaring demand for AI-related high-bandwidth memory.
SK Hynix, as the dominant global supplier of HBM, recently signed a multi-year HBM4 supply agreement with Nvidia, further solidifying its core position in the AI infrastructure supply chain. The company's market capitalization has surpassed that of Samsung Electronics, making it South Korea's most valuable enterprise. This symbolic shift marks a reshuffling of the country's corporate hierarchy amid the AI wave.
Samsung Electronics has similarly benefited from AI chip demand, with its market value crossing the $1 trillion threshold this year. The profit surge at both companies has delivered unprecedented tax revenues to the South Korean government, sparking a nationwide debate over how to distribute this wealth.
Three Pillars of the Future Response Fund
According to Yonhap News Agency, South Korea's presidential chief of staff Kang Hoon-sik stated that the fund would transform extra tax revenue into investment resources for future generations. The government has structured the fund around three priorities:
First, investment in new growth engines, with a focus on AI, advanced manufacturing, and related technology sectors. This direction aims to convert the current semiconductor boom into broader technological ecosystem advantages, avoiding excessive dependence on a single industry cycle.
Second, addressing economic polarization. South Korea has experienced widening wealth gaps in recent years, with surging profits at large conglomerates contrasting sharply with stagnant incomes among small and medium enterprises and ordinary households. The fund will partially address this gap to promote more inclusive economic growth.
Third, supporting housing, entrepreneurship, and employment needs for people in their 20s and 30s. Young Koreans face pressures including high housing costs and intense employment competition. The government hopes to alleviate intergenerational inequality through direct support, preventing the escalation of social tensions.
South Korea's Role in the Global AI Supply Chain
The dominance of SK Hynix and Samsung in the HBM market has positioned South Korea as a critical node in the global AI infrastructure supply chain. HBM is a core component required for AI training and inference, with demand surging alongside the proliferation of large language models and generative AI applications. SK Hynix supplies the majority of global HBM capacity and has established deep partnerships with AI chip designers such as Nvidia and AMD.
This supply chain position has brought enormous economic benefits to South Korea, but also carries risks. The semiconductor industry is highly cyclical, and the current AI boom may face demand adjustments or technological shifts in the coming years. The government's establishment of a future response fund is partly intended to stockpile resources during prosperous periods to weather potential cyclical downturns.
Additionally, geopolitical factors add uncertainty. U.S. chip export controls targeting China, along with semiconductor self-sufficiency strategies in the European Union and Japan, could reshape the global supply chain landscape. South Korea needs to balance technological leadership with market diversification.
The Complementary Significance of Foreign Exchange Reform
The launch of 24-hour won trading provides important support for the modernization of South Korea's financial market infrastructure. Traditionally, won trading was limited to Korean domestic trading hours, which restricted the convenience of international investor participation and increased exchange rate volatility risks. The 24-hour trading mechanism will enhance the internationalization of the won and reduce currency hedging costs for businesses and investors.
For semiconductor companies, this reform has practical significance. The revenues of Samsung and SK Hynix are highly dependent on dollar-denominated international markets, and exchange rate fluctuations directly impact their profit performance. A more flexible foreign exchange market will help companies manage currency risk more effectively and improve financial stability.
From a broader perspective, foreign exchange reform and the future response fund together constitute South Korea's dual-track strategy for the AI era: attracting international capital through financial market modernization while consolidating technological advantages through industrial tax reinvestment.
Considerations of Intergenerational Equity and Social Stability
The government's emphasis on supporting people in their 20s and 30s reflects deeper concerns about social stability. The economic pressures facing young Koreans are relatively pronounced among developed countries: housing price-to-income ratios in major cities like Seoul remain stubbornly high, competition for employment at large corporations is fierce, and startup success rates are relatively low.
Meanwhile, surging profits at large conglomerates have not fully translated into income growth for ordinary citizens. This structural contradiction becomes more pronounced against the backdrop of the semiconductor boom: corporate profits have leaped from 90 trillion to 600 trillion won, yet real purchasing power improvements for average households remain limited.
The future response fund attempts to alleviate this contradiction through fiscal redistribution. However, the actual effectiveness will depend on the fund's governance structure, investment decision-making mechanisms, and coordination with existing policy tools. If the fund primarily flows toward large projects or entrenched interest groups, it may fail to genuinely benefit the target population.
Risks and Challenges
Despite the positive vision of the future response fund, its implementation faces multiple challenges. First, the sustainability of semiconductor tax revenues is uncertain. The current profit surge is primarily driven by AI demand, and if AI market growth slows or technological pathways shift, the tax base could contract rapidly.
Second, the fund's investment efficiency and transparency are crucial. South Korea has historically established multiple government-guided funds, some of which have been criticized for opaque decision-making and low investment returns. How to ensure the future response fund genuinely serves long-term goals rather than becoming a short-term political tool is a question the government must answer.
Third, investments in AI and advanced manufacturing need to form effective synergies with the private sector. Korean companies already make substantial autonomous investments in these areas, so government funds should focus on areas of market failure, such as basic research and development, talent cultivation, and support for small and medium enterprises, avoiding duplication or competition with private investment.
Finally, the international competitive environment is changing rapidly. The United States, European Union, and China are all investing heavily in AI and semiconductors. South Korea needs to maintain technological leadership while avoiding subsidy races or overcapacity traps.
Implications for Global Markets
South Korea's approach offers a reference for other resource-dependent or cyclical industry-reliant countries. How to convert short-term prosperity into long-term competitiveness, and how to balance economic growth with social equity, are common challenges facing many nations. The dual-track strategy demonstrates how a mid-sized economy can navigate the opportunities and challenges of technological disruption, with outcomes that will provide valuable insights for other countries and influence the evolution of the global AI and semiconductor industry landscape.
