From Chip Profits to AI Power: South Korea Unveils $597bn 2027 Budget.

South Korea has proposed a record 821 trillion won ($596.92 billion) budget for 2027, using a surge in semiconductor-driven revenues to finance an aggressive push into artificial intelligence, advanced technology and other future industries.

The proposed budget represents a 12.8 per cent increase from this year and marks the largest year-on-year increase in South Korea’s spending on record. The plan reflects President Lee Jae Myung’s shift towards expansionary fiscal policy after several years of tighter government spending under his predecessor.

At the centre of the strategy is the belief that South Korea cannot rely indefinitely on its existing strength in conventional semiconductor manufacturing. The government is instead seeking to use the current AI-driven chip boom to build capacity in technologies that could determine the next phase of global economic competition.

The numbers behind the spending plan show why Seoul believes it has an opportunity to do so.

South Korea expects government revenue to rise 40.7 per cent to 584.4 trillion won in 2027. Corporate tax revenue is projected to more than double to 216.7 trillion won, with the increase largely linked to the exceptional profits being generated by semiconductor companies benefiting from strong global demand for AI-related chips.

Exports provide another indication of the strength of the technology cycle.

South Korean exports jumped 68.7 per cent year-on-year to $98.26 billion in August, extending the country’s export growth to 15 consecutive months. The preliminary trade surplus stood at $34.75 billion, with semiconductor and other technology products driving much of the increase.

The government now wants to convert that export strength into broader technological capacity.

It plans to invest 21.3 trillion won in three major technology areas; semiconductors, physical AI and AI data centres, with support covering infrastructure as well as technology development.

The proposed spending is not limited to artificial intelligence.

The government has also established a 162.3 trillion won Future Response Fund, designed to channel excess revenues into long-term priorities including future growth industries, youth support, regional development and talent development.

That approach is significant because Seoul is attempting to address a longer-term economic problem: how to ensure that the extraordinary profits generated by the semiconductor cycle translate into wider productivity, employment and technological capabilities.

The government is therefore putting money into infrastructure that could support the next generation of chip production and AI development rather than simply treating higher tax receipts as temporary income.

But the strategy also carries risks.

The global semiconductor industry is highly cyclical, and South Korea’s recent revenue gains have been heavily influenced by unusually strong demand for AI-related hardware. A prolonged downturn in the chip market could reduce the tax revenues that are helping finance the expansion.

There is also a monetary-policy complication.

The Bank of Korea recently raised its benchmark interest rate to 3.00 per cent, while upgrading its 2026 economic growth forecast to 3.3 per cent from 2.6 per cent. President Lee has said another interest-rate increase is unavoidable, highlighting concerns over inflation and financial stability.

That leaves South Korea pursuing two different economic objectives at once.

The government is increasing investment to strengthen future growth, while the central bank is tightening financial conditions to manage inflation and other economic risks.

For Lee’s administration, the central question is whether the current semiconductor windfall can be turned into something more durable.

If the investments in AI, data centres, chips, infrastructure and skills succeed, South Korea could emerge from the current technology boom with a broader economic base and stronger position in the global AI race.

If the spending simply follows a temporary chip cycle, however, the country could find itself with a much larger fiscal commitment after the exceptional revenues have faded.

For now, Seoul is choosing to invest.

The 821 trillion won budget, the 40.7 per cent projected increase in revenue, the 21.3 trillion won technology allocation and the 162.3 trillion won Future Response Fund all point to the same strategy: use today’s semiconductor boom to finance tomorrow’s technological economy.

The proposal still requires approval by South Korea’s parliament.
