The Korean semiconductor materials supply chain is finally entering a normalization phase following the end of the U.S.-Iran war.
The decisive turning point was the June 14th ceasefire agreement, which included plans to reopen the Strait of Hormuz. This single event fundamentally changed the operating environment. For the past three months, the primary challenge was managing war-driven shocks to shipping and energy. Now, the main focus has shifted to allocating production capacity to meet the relentless demand for AI memory chips like HBM.
Let's trace the causal chain to understand this shift. First, the conflict that began in March created a severe supply shock. The closure of the Strait of Hormuz caused oil and logistics costs to surge and disrupted the supply of critical materials like helium, forcing materials suppliers to draw down their inventories. Second, throughout this period, the AI-driven memory supercycle was gaining momentum. Samsung and SK hynix were accelerating investments to expand HBM production, creating a powerful underlying demand for materials. Third, the ceasefire acted as the final catalyst. It removed the geopolitical constraints, allowing the pent-up demand from the AI boom to drive the market.
The market's reaction was immediate and clear. Oil prices fell sharply on the ceasefire news, signaling an easing of cost pressures for petrochemicals and freight. This normalization comes at a time when memory chip prices are already soaring—DRAM contract prices jumped over 50% in the second quarter. This gives materials suppliers both the customer tolerance and the margin headroom to pass through the costs they absorbed during the conflict.
In essence, the bottleneck has shifted from geopolitical risk to production capacity. With demand for AI chips acting as the primary driver, materials suppliers now find themselves in a much stronger position to negotiate prices and rebuild their inventories, heralding a new phase of the supercycle that extends to chemicals, gases, and precursors.
- Strait of Hormuz: A strategically important waterway between Iran and Oman, through which a significant portion of the world's oil and gas passes.
- HBM (High Bandwidth Memory): A type of high-performance memory used in GPUs and other processors for AI and high-performance computing applications.
- Price Pass-through: The process by which a business passes on increases in its costs to the final price paid by the customer.
