Asian AI chip stocks surge following Iran-US peace deal

🔑 Enhanced Key Takeaways

• •The diplomatic breakthrough between the US and Iran, formalized through a memorandum of understanding (MOU) on June 15, 2026, aims to end a months-long conflict, reopen the critical Strait of Hormuz, and unfreeze $25 billion in Iranian assets, with further negotiations on a final peace deal and Iran's nuclear program expected within 60 days.
• •SoftBank's 10% share surge is underpinned by its aggressive AI investment strategy, including a cumulative $64.6 billion investment in OpenAI (representing approximately 13% ownership), the acquisition of US-based semiconductor design company Ampere, and plans to build three AI-focused data centers in France with an initial investment of €45 billion.
• •SK Hynix's gains are driven by its leadership in High Bandwidth Memory (HBM) chips, particularly HBM3E, and strategic plans to double its memory chip capacity over the next five years, including a 5.3 trillion KRW investment in its M15X fab for HBM production by 2026 and co-development of HBM4 with TSMC.
• •Samsung Electronics' rally is supported by its significant commitment of over $73 billion (₩110 trillion) in 2026 towards AI chip development and capacity expansion, focusing on next-generation AI chips and advanced foundry processes, and its reported talks with Google to manufacture components for future Tensor Processing Units (TPUs) using 2-nanometer technology.
• •The Nikkei 225's historic high above 69,000, reaching 69,317.50 on June 15, 2026, was largely propelled by risk appetite following the US-Iran deal, which is expected to ease oil price concerns and reduce cost pressures for energy importers like Japan, with technology and AI-related shares accounting for over 56% of the index's weighting.
