Samsung and SK Hynix Hit Record Highs While Oil, Yen and Indonesia Raise New Market Risks
MARKET INSIDER – Asia’s financial markets are sending a powerful signal to global investors: artificial intelligence is increasingly outweighing geopolitical uncertainty. As an interim U.S.-Iran agreement eases fears of a major energy shock and shipping through the Strait of Hormuz resumes, investors are rotating back into technology and growth assets, pushing South Korea’s benchmark Kospi Index above the historic 9,000 level for the first time.
The rally highlights a growing divide across Asia. While South Korean technology giants are benefiting from the global AI infrastructure race, concerns over market transparency in Indonesia and renewed pressure on Japan’s currency are reminding investors that regional risks remain far from resolved.
South Korea emerged as the region’s standout performer on Friday, with the Kospi climbing another 2.8% after breaking through the 9,000 milestone a day earlier. The surge was fueled by record-breaking gains in semiconductor leaders Samsung Electronics and SK Hynix, underscoring investor enthusiasm for companies at the center of the global AI supply chain.
SK Hynix jumped more than 7% to a fresh all-time high after announcing that it had supplied samples of its next-generation 12-layer HBM4E memory chips to major customers. High-bandwidth memory has become one of the most critical components powering advanced AI systems, and analysts say demand continues to outstrip supply as hyperscalers and technology companies accelerate investment in AI infrastructure worldwide.
Elsewhere, oil markets remained surprisingly calm despite lingering skepticism surrounding the U.S.-Iran agreement. Brent crude slipped below $80 per barrel as tanker traffic through the Strait of Hormuz continued to recover. The easing of immediate supply concerns has shifted investor attention back toward global demand trends, even as OPEC maintains confidence that long-term oil consumption remains resilient.
In Japan, investors are facing a different challenge. The yen weakened beyond 161 per U.S. dollar, approaching levels not seen in nearly four decades and reviving speculation that Japanese authorities could intervene in currency markets. At the same time, inflation remained relatively subdued, providing policymakers with limited urgency to tighten monetary conditions despite the currency’s decline.
Meanwhile, Indonesia faces renewed scrutiny after MSCI again raised concerns about market transparency, citing opaque ownership structures and signs of coordinated trading activity. The warning comes as the Jakarta Composite Index remains nearly 30% lower this year, highlighting the increasing importance global investors place on governance, liquidity, and market accessibility when allocating capital across emerging markets.
The bigger story is that Asia’s investment landscape is becoming increasingly selective. Capital is flowing aggressively toward markets and companies directly tied to the AI revolution, while countries facing governance concerns or macroeconomic instability risk being left behind. If current trends continue, the next phase of global capital flows may be determined less by geography and more by which economies can credibly position themselves as essential players in the AI-driven future.
