Fueled by Semiconductor Boom, Total Spending Set to Surpass 1,000 Trillion Won by 2030

The South Korean government has finalized its draft budget for 2027, setting a record-high total expenditure of 820.9 trillion won (approximately $600 billion). Driven by a massive super-boom in the semiconductor sector, the government is expanding fiscal spending at an annual growth rate of 12.8%—surpassing the 10.6% rate recorded in 2009 during aggressive fiscal stimulus deployed to overcome the global financial crisis.

"Amid rapid shifts in the global order, our budget for next year must serve as a sturdy stepping stone to propel South Korea into a hyper-gap leading nation, while acting as a catalyst for tangible improvements in the daily lives of our citizens." — President Lee Jae-myung
