SK Hynix’s AI Cash Haul Reshapes Korea’s Credit Market
The artificial-intelligence investment boom has fueled demand for high-bandwidth memory, delivering a surge in earnings and liquidity for SK Hynix, one of the technology’s leading suppliers. With its cash reserves swelling to 88 trillion won, the chipmaker has emerged as an unusually powerful force in South Korea’s corporate credit market, channeling its AI windfall into bonds and short-term debt while gaining influence over pricing and availability.
So far in 2026, SK Hynix has purchased as much as $28 billion of South Korean corporate bonds and commercial paper, making it a major source of demand and liquidity. The buying spree has supported issuers and helped absorb supply, but it has also made high-quality securities scarcer, pushed prices higher and complicated portfolio allocation for other institutional investors. The resulting imbalance is giving the memory-chip giant growing sway over a market traditionally shaped by financial institutions.
