SEOUL, November 3: President Lee Jae Myung has asked South Korea’s National Assembly to pass a record ₩820.9 trillion budget for 2027, up 12.8% from this year, in a speech that framed the plan as “growth for all”. The budget nearly doubles spending on artificial intelligence and chip-related projects to ₩21.3 trillion, sets up a ₩162.3 trillion “Future Response Fund” from a surge in tax revenue, and still forecasts a smaller deficit and lower debt ratio because chip-driven tax receipts are soaring.
Key highlights
- Total spending: ₩820.9 trillion (about $610 billion), up 12.8% — the fastest increase on record, according to the government.
- Total revenue: ₩880.8 trillion, including ₩584.4 trillion in national taxes, boosted by corporate and income taxes from the semiconductor boom.
- AI and three megaprojects: ₩21.3 trillion, up 97.2% — including ₩4.7 trillion for frontier AI models and GPUs and ₩3.4 trillion for semiconductors.
- The managed fiscal deficit is forecast at 0.1% of GDP and the national debt ratio at 48.3%, down from 51.6%.
- Lee delivered the budget address to the National Assembly on November 2 and urged lawmakers to pass it by the December 2 legal deadline.
The 2027 budget in numbers
| Item | 2027 proposal |
|---|---|
| Total spending | ₩820.9 trillion (+12.8%) |
| Total revenue | ₩880.8 trillion |
| National tax revenue | ₩584.4 trillion |
| Managed fiscal balance | −0.1% of GDP (3.8 points better than 2026) |
| National debt | 48.3% of GDP (2026: 51.6%) |
| Future Response Fund | ₩162.3 trillion of extra tax revenue above the 10-year trend |
| AI and three megaprojects | ₩21.3 trillion (+97.2%) |
| R&D in national strategic technologies | ₩13.8 trillion |
| Regional growth and national land transformation | ₩33 trillion |
Where the AI money goes
| Area | Amount |
|---|---|
| Frontier AI models and GPUs | ₩4.7 trillion |
| Semiconductors | ₩3.4 trillion |
| Physical AI demonstrations | ₩2.6 trillion |
| Power, water and industrial-complex infrastructure | ₩2.1 trillion |
| Total for AI and three megaprojects | ₩21.3 trillion |
The Future Response Fund is built from ₩162.3 trillion of 2027 tax revenue above its ten-year trend. Of that, ₩45.4 trillion is earmarked for youth, growth engines, regions and education, and ₩12.5 trillion will be used to reduce new government bond issuance, according to the budget documents. Defence spending is set to rise about 8% to more than ₩73 trillion, covering projects such as nuclear-powered submarines and the KF-21 fighter.
Our calculation
- Revenue outruns spending: total revenue exceeds total spending by about ₩59.9 trillion — the chip boom is paying for the expansion.
- This year’s base: a 12.8% increase to ₩820.9 trillion implies a 2026 budget of roughly ₩727.7 trillion.
- AI’s slice: ₩21.3 trillion is about 2.6% of total spending, but almost double last year’s amount.
- Windfall scale: the ₩162.3 trillion fund equals about 20% of the whole budget.
What it means
South Korea is using an unusual moment — record chip exports and a tax windfall — to spend more and borrow less at the same time. The bet is that public money for AI models, GPUs, chips and power infrastructure will keep Korea competitive as the AI hardware cycle continues. The risk is that much of the revenue depends on memory-chip prices; if they fall, the windfall shrinks. For India and other Asian economies competing for chip and AI investment, Korea’s budget is a sign of how aggressively governments are now subsidising the sector.
What to watch
- National Assembly negotiations ahead of the December 2 deadline, and any cuts the opposition demands.
- How the Future Response Fund is governed and audited.
- Semiconductor prices and tax receipts, which underpin the revenue forecast.
