Posco bets W6.7tr on overseas steel push, eyes Southeast Asia's first integrated auto-sheet mill
Posco Holdings said it will invest 29.1 trillion won from 2024-2028, with 6.7 trillion won allocated to overseas steel. It targets doubling overseas crude steel capacity from about 5 million tons to 10 million tons by 2031, including an integrated automotive sheet system in Indonesia via Krakatau Posco. The plan also covers India and US projects; Q2 overseas sales rose to 1.37 trillion won but operating profit fell to 47 billion won.
How this was made

The 30-second read
Why it matters
The disclosed capex allocation and capacity targets provide a tangible roadmap for investors to model future earnings contribution from overseas integrated production, especially automotive sheet in Indonesia and higher-value mix in India and the US.
Market read
Traders can update medium-term positioning in Posco-linked steel exposure based on the scale and geography of the overseas capacity build and the stated margin recovery thesis.
What to watch
Execution risk is high: the second-phase groundbreaking date is not set, and the US and India projects depend on long lead times, permitting, and demand ramp for automotive sheet.
Background
Posco outlined a corporate value enhancement strategy to strengthen domestic competitiveness while scaling overseas steel capacity, centered on the US, India, and Indonesia.
Market effects
Reinforces the steel sector’s shift toward overseas capacity and low-carbon process conversion, potentially affecting regional supply-demand expectations in automotive sheet.
Indonesia expansion plan could intensify competition for automotive steel sheet supply, while India and US projects target higher-value product mix and trade-barrier mitigation.
Large overseas capacity buildout may influence global pricing dynamics for hot-rolled, cold-rolled, and coated automotive-grade steel over the next several years.
Counterpoint
The plan’s profitability claims may be optimistic given the article’s own note that operating margins have been pressured by raw materials, FX, and a deteriorating export environment.
