[Market Analysis] The surge in DRAM prices: Is it a sign of inflation or a precursor to deflationary shocks?

Memory semiconductors have quietly become the most important raw material in the global economy. As DRAM prices have surged in recent months, Samsung Electronics and SK Hynix have provided strong upward momentum for the KOSPI index, which accounts for about 35% of Korea’s market capitalization. However, the tight supply in the memory market has sparked an interesting macroeconomic question: Is this ultimately inflationary fuel for the global economy or the early stage of a deflationary collapse?

Why Memory Semiconductors Are So Important Now

DRAM is called the “worker bee” of the digital world. It is the main memory that runs when devices are powered on, from AI servers to cars, smartphones, and laptops—almost all electronic devices rely on it. Even NVIDIA’s GPUs are heavily dependent on DRAM chips.

While much has been understood about NVIDIA and the rapid growth of semiconductors, the dramatic changes happening in the DRAM market have received relatively little attention. Remember when the COVID-19 pandemic disrupted supply chains and used car prices nearly matched new car prices? At that time, new cars lacked essential chips, and used cars with chips commanded a premium. Today, a similar dynamic is unfolding in the memory market.

Inflation Scenario: Pricing Power Created by Scarcity

Tight memory supply has a straightforward first effect: rising prices. The biggest beneficiaries are manufacturers like Samsung Electronics, SK Hynix, and Micron.

The memory market is one of the most cyclical industries globally. When capacity utilization rises and inventories decrease, pricing power shifts sharply in favor of producers, and profit margins expand rapidly.

Rising memory prices directly impact AI servers, cloud infrastructure, PCs, TVs, smartphones, network equipment, and cars. Especially in AI, memory is a critical component. A subcategory of DRAM—High Bandwidth Memory (HBM)—is essential for running the latest GPUs. Companies like Microsoft, Tesla, and Meta require large amounts of high-performance memory to operate their flagship AI accelerators as designed.

As memory becomes more expensive, server construction costs increase, cloud infrastructure investments rise, and hardware prices go up. This is a typical cost-push inflation structure. Currently, AI infrastructure investments are dominated by large-scale companies with enormous capital, and demand is not particularly sensitive to price. The increased input costs are absorbed rather than immediately suppressing investment. This is how inflationary pressures work, with the burden of high prices falling mainly on non-mega corporations.

Deflation Scenario: When Scarcity and Prices Stifle Growth

However, what if the issue is not just simple price increases but the very “availability” of memory?

Imagine that due to insatiable demand from mega-corporations, non-mega companies find it difficult to secure supply of memory chips in both price and quantity. Production lines stall, revenues slow, and semi-finished inventory piles up. For companies with high fixed costs and leverage, this can quickly become a very dangerous situation.

Unlike large tech firms with ample cash reserves and easy access to credit markets, small and medium-sized enterprises lack financial buffers. This creates a transmission path to economic recession: demand destruction, increased bankruptcies, rising unemployment, and a chain reaction of widening credit spreads. Given that current credit spreads are trading near historic lows, this warrants particular attention.

Time is the enemy. The longer chip prices stay high, the greater the macroeconomic shock. Wealthy tech companies seem unlikely to retreat soon. Recently, Google rapidly issued multiple tranches of bonds totaling $32 billion, including a £5.5 billion 100-year bond in GBP, which received bids totaling £30 billion, showing massive oversubscription.

Implications for the Korean Market

This debate is especially important for Korean investors. With Samsung Electronics and SK Hynix accounting for about 35% of KOSPI’s market cap, the rise in DRAM prices has been a core driver of Korea’s stock market. As long as the super cycle in memory continues, the performance and stock prices of these two companies will likely enjoy strong tailwinds.

But there’s another side. If memory prices remain elevated for a long period, it could harm the very foundation of global demand. When the purchasing power of non-mega companies is exhausted and the economy slows down broadly, memory demand will eventually decline. Given the extreme cyclicality of the memory industry, the current boom cannot last forever.

Investors should watch credit spread changes in industries heavily reliant on memory chips and unemployment trends. The direction of inflation remains uncertain.
