Samsung Electronics and SK Hynix are embarking on massive investments totaling 3,200 trillion won ($2.07 trillion) in South Korea's semiconductor sector, aiming to capitalize on the artificial intelligence boom. This significant expansion, which includes a new chip cluster in the southwest and accelerated construction in Yongin, seeks to double the nation's memory chip production capacity within five years. The move has garnered support from President Lee Jae Myung, signaling a departure from previous caution driven by past industry downturns.
However, the ambitious capacity buildout is raising concerns among analysts about the potential for oversupply if the current rate of AI spending does not continue. Morningstar analyst Jing Jie Yu noted that accelerating capital expenditures over the next decade increases the risk of a long-term oversupply, dependent on sustained AI hyperscaler expansion.
Some experts, like Professor Lee Jong-ho, suggest the investments might be too rapid given the uncertain future demand. SK Hynix Chairman Chey Tae-won had previously expressed skepticism about plans for chip factories in the southwest, though neither company has explicitly detailed the reasons for their shift in strategy. Analysts like CW Chung from Nomura suggest investing in other regions could hedge against uncertainties surrounding the Yongin cluster.
Despite the risks, analysts believe the companies will leverage lessons from past cycles, with memory producers retaining flexibility to adjust investment pace. Samsung plans to invest 2,100 trillion won through 2040, with spending adjustable for market conditions. The South Korean government, meanwhile, prioritizes momentum, with presidential chief of staff Kang Hoon-sik stating the aim to complete the chip cluster before President Lee's term ends in 2030. Koh Taebong of iM Securities views the move as a strategic bet for South Korea to become a top AI power.
