South Korea exports jump 55.6% on AI chip boom

South Korea’s exports rose 55.6% year-on-year to US$21.5 billion in the March 1-10 period on strong overseas demand for semiconductors, the Korea Customs Service said.

Imports climbed 21.7% to US$19.4 billion, leaving a trade surplus of US$2.1 billion.

Semiconductor exports surged 175.9% to a record high of US$7.6 billion for the first 10 days of a month and made up 35.3% of total exports, up 15.4 percentage points year-on-year.

Petroleum product shipments rose 44.1% to US$1.4 billion while automobile exports dropped 13.9% to US$1.4 billion and vessel shipments fell 61.9% to US$465 million.

By destination, exports to China jumped 91.2% to US$5.1 billion, and shipments to the United States rose 69.9% to US$4.2 billion.

🧠 Food for thought

Implications, context, and why it matters.

The AI boom is fueling a memory chip supercycle

  • Rising AI spending has lifted chip orders. SK hynix says High Bandwidth Memory (HBM) revenue more than doubled in 2024 1.
  • Limited supply has opened room for price hikes. Samsung told large customers its DRAM (dynamic random-access memory) prices will rise 1530% 2.
  • Profits have jumped. SK hynix posted a 58.4% fourth-quarter operating profit margin 2. It beat Taiwan Semiconductor Manufacturing Co. (TSMC), the world’s largest contract chipmaker, for the first time in seven years 2.
  • Politics also shapes demand. Washington has proposed a procurement rule aimed at Chinese semiconductors. The rule could strengthen South Korean memory makers 2.

South Korea is leveraging the AI boom to reshape its economy

  • Strong exports sit behind a national plan. The government plans a 700 trillion won ($534 billion) investment and 10 new fabrication plants (fabs) by 2047 3.
  • The effort aims to move beyond memory chips. It also seeks to strengthen the fabless (chip companies that design but do not manufacture chips) sector and chip design ecosystem 3.
  • Officials want activity beyond existing clusters. A new southern corridor will focus on chip packaging (the process of assembling and protecting finished chips), power semiconductors (chips used to control and convert electrical power), and components 4.
  • Security goals run through the plan. One project targets self-reliance in defense semiconductors. Imports currently account for 99% 3.
