## Summary

International investment banks raised their 2026 GDP growth forecasts for [South Korea](/ko/entity/south-korea) to an average of 3.2% as of August 10, citing consecutive records in semiconductor exports driven by AI chip demand. [Sk Hynix](/ko/entity/corporate/sk-hynix) confirmed it was expanding domestic manufacturing capacity across high-bandwidth memory (HBM), DRAM, NAND, and advanced packaging lines in South Korea to keep up with AI memory orders. South Korea's economists describe the current period as a semiconductor super-cycle tied specifically to AI investment, distinguishing it from the cyclical restocking that characterized previous chip booms. Bloomberg separately pegged the 2026 growth forecast at 3.3%.

## Why it matters

South Korea's economy is highly concentrated in semiconductors: chips account for roughly a fifth of its exports, so a structural AI-driven demand cycle affects the entire economy through trade surpluses, investment flows, and the won's value. SK Hynix's HBM is the enabling component for Nvidia's H100 and successor GPUs; the company's capacity decisions directly affect how quickly AI infrastructure can scale globally. A sustained growth forecast upgrade also signals that the Korean government has room to tighten fiscal policy if needed.

## What to watch

- SK Hynix's official capex guidance update: whether the South Korean plant expansions are confirmed with specific investment figures
- Whether rival Samsung Electronics matches SK Hynix's capacity ramp or cedes HBM market share further
- South Korea's monthly trade data: sustained export records in chips would validate the 3.2-3.3% growth scenario
- Demand signal: Nvidia's next earnings call on HBM allocation and pricing
