On August 7, the AI boom has prompted global tech giants to raise huge sums of money by issuing bonds, but for at least one major chipmaker, involvement in the credit markets extends far beyond just financing. According to sources familiar with the matter, South Korean chip giant SK Hynix is leveraging its growing cash reserves to expand its investments in the South Korean domestic corporate bond market. Several credit analysts and market participants estimate that the scale of bonds purchased by SK Hynix this year ranges from approximately KRW 10 trillion to KRW 40 trillion (approximately USD 7 billion to USD 28 billion), with the higher estimate also covering commercial paper. New job postings recently released by SK Hynix further indicate its intensified efforts in the bond market. The role involves managing, strategizing, and hedging the company's funds, with investments spanning government bonds, corporate bonds, and short-term debt instruments. On a global scale, it is not uncommon for companies to make periodic investments in the credit markets, but the direct participation of corporate funds in the bond market, which is typically dominated by institutional investors, remains notable. Despite significantly increasing its capital expenditures in recent years, SK Hynix continues to accumulate investable funds. The company's cash and cash equivalents reached KRW 88 trillion at the end of the second quarter, up nearly 62% from the previous quarter.
