Leveraging the semiconductor boom, South Korea is heavily investing in AI! Its 820 trillion won budget has been finalized, marking the highest spending growth rate in history.

The South Korean government has officially approved the 2027 budget, ushering in an unprecedented era of expansionary fiscal policy supported by fiscal surpluses brought about by the semiconductor supercycle. This policy deeply binds national resources to the AI industry strategy and future risk hedging.

On September 1, the South Korean government held a cabinet meeting and approved the 2027 budget, which totals a record 820.9 trillion won, a surge of 93 trillion won compared to this year, marking the highest expenditure growth rate in history. The core increase is focused on technology and the future: 21.3 trillion won will be heavily invested in three major AI projects, while the 162.3 trillion won "Future Response Fund" has been officially launched.

The robust recovery of the semiconductor industry underpins this fiscal expansion. Total revenue is projected to surge 30.4% to 880.8 trillion won next year, driving the national debt ratio down from 51.6% to 48.3%. This "using surplus to offset deficit" fiscal maneuver provides South Korea with ample ammunition in the fierce global technology arms race.

However, this aggressive spending expansion also comes with significant long-term risks. Over 100 trillion won in idle funds have sparked controversy over "slush funds" that circumvent parliamentary oversight, while the ever-growing welfare and administrative expenditures are raising market concerns about their actual rate of return on investment and future fiscal sustainability.

South Korea invests 21.3 trillion won in three major AI projects.

Against the backdrop of artificial intelligence reshaping the global industrial landscape, the South Korean government is accelerating its efforts to gain a technological advantage through fiscal tools. The 2027 budget clearly states that 21.3 trillion won will be invested in AI next year, nearly double this year's 10.8 trillion won.

This massive investment will be precisely channeled into three mega-projects: semiconductors, physical AI, and AIDC (AI Data Centers). This fiscal focus resonates strongly with private capital. Previously, the South Korean government, in conjunction with Samsung Group and SK Group, announced a ten-year mega-investment plan totaling 4.755 trillion won, including an 800 trillion won investment in four semiconductor manufacturing plants in southwestern South Korea. This targeted allocation of government budget aims to deeply synergize with the capacity expansion plans of the chaebols, further solidifying South Korea's core position in the global memory chip and AI computing power supply chain.

The 162 trillion yuan "future response fund" launch and regulatory controversies

Faced with the rare situation of revenue exceeding expenditure, the South Korean government has played another key card – formally establishing the "Future Response Fund ." The fund is projected to generate 162.3 trillion won in revenue next year, primarily funded by tax surpluses from the semiconductor boom.

In terms of fund allocation, 45.4 trillion won will be used for youth support and investment in key growth drivers, while 12.5 trillion won will be used to reduce the issuance of new government bonds. However, a staggering 104.4 trillion won will be retained as idle funds, essentially creating a "contingency fund" exceeding 100 trillion won. This design has sparked intense market and political controversy. Critics argue that such a massive amount of idle funds could become a "slush fund" that evades parliamentary oversight and is arbitrarily controlled by the government, undermining fiscal transparency and the efficiency of fund allocation.

Semiconductor boom fuels expansion, but long-term fiscal concerns emerge.

The cyclical boom in the semiconductor industry has provided a solid foundation for South Korea's fiscal expansion. South Korea's total revenue is projected to reach 880.8 trillion won next year, a significant increase of 205.6 trillion won from this year, with national tax revenue surging by 194.2 trillion won, driven by strong semiconductor exports. As GDP growth outpaces debt growth, the national debt ratio is expected to improve from 51.6% to 48.3%.

However, short-term fiscal easing cannot mask long-term structural concerns. According to the "National Fiscal Management Plan 2026-2030," the South Korean government budget will exceed 1,000 trillion won by 2030. During President Lee Jae-myung's term, the budget increase is projected to reach 331.9 trillion won, almost equivalent to the total budget increase during the 13-year terms of the previous three presidents.

Furthermore, the rapid expansion of rigid expenditures is exacerbating fiscal vulnerability. Next year, civil servant salaries will increase by 3.9%, the highest increase since 2011, and the number of national civil servants will increase by 3,851. Meanwhile, welfare expenditures such as marriage, childbirth, and childcare packages are growing exponentially. Analysts warn that once government spending expands, it is extremely difficult to cut, and these massive projects, lacking actual investment performance assessments, could easily become "boomerangs" that backfire on public finances. With the widespread adoption of AI potentially exacerbating structural employment contradictions, simply casting a wide net with funds rather than implementing precise industrial and employment solutions is unlikely to provide substantial long-term growth momentum for the South Korean economy.
