HBM Investment and the Debate Over Easing the Separation of Banking and Commerce

Samsung Electronics and SK Hynix are moving to supply massive amounts of high-bandwidth memory (HBM) to OpenAI’s “Stargate” AI project. With projected demand reaching as much as 100 trillion won, President Lee signaled a willingness to consider easing Korea’s long-standing restrictions on the separation of banking and commerce. The debate now centers on whether loosening this rule would fuel innovation or create systemic risks.
💡 What Does Separation of Banking and Commerce Mean?
The principle prohibits industrial capital from controlling banks and financial institutions. In simple terms, large conglomerates cannot own banks outright, and banks cannot directly dominate industrial firms. Korea tightened these rules after the 1997 Asian Financial Crisis to prevent reckless expansion and safeguard financial stability.
| Category | Description |
|---|---|
| Financial Capital | Banks, securities firms, and insurers managing funds |
| Industrial Capital | Manufacturing, IT, and service companies producing goods and services |
| Policy Goal | Prevent concentration of power, ensure financial stability, protect fair competition |
📊 Why Is Easing Being Considered Now?
OpenAI’s project is said to require as many as 900,000 wafers a month, a volume rivaling global production capacity. To deliver such supply, Samsung and SK Hynix would need investments exceeding tens of billions of dollars. With Korea’s current restrictions, raising capital on this scale is difficult, which is why the President suggested possible easing “without causing monopoly abuses.”
⚖️ Potential Benefits and Risks
Relaxing the rule could allow tech giants to use financial affiliates to establish large-scale funds and attract investors more flexibly. This might strengthen Korea’s position in the global semiconductor race. On the other hand, opponents warn that financial instability could spill over into the broader economy and that economic power would become even more concentrated in a handful of conglomerates.
| Positive Outlook | Concerns |
|---|---|
| Securing funds for mega AI/semiconductor projects | Wider financial risk exposure |
| Enhancing global competitiveness | Concentration of corporate power |
| Participation in large-scale global ventures | Risk of monopolistic practices |
🌍 What Lies Ahead
The issue is not just about Samsung and SK. It is a test of Korea’s broader economic strategy and financial safeguards. Political leaders, regulators, and industry stakeholders must find a compromise that balances investment freedom with systemic safety. Without clear safeguards, easing the rule could backfire and undermine the very stability that allowed Korea’s tech sector to thrive. The debate over easing the separation of banking and commerce will likely shape the country’s competitiveness in the era of AI-driven industries.
