In the second quarter of this year, South Korea's economy grew by 0.6% compared to the previous quarter. This figure is three times higher than the Bank of Korea's initial forecast of 0.2%. Following a 1.8% growth in the first quarter, this marks two consecutive quarters of growth, showcasing the resilience of the South Korean economy amid geopolitical tensions in the Middle East, rising international oil prices, and U.S. tariff pressures.
However, it would be a mistake to assume that the economy's fundamentals have strengthened solely based on this growth rate. A significant portion of this growth can be attributed to the semiconductor industry. Exports increased by 1.4%, primarily driven by semiconductors and machinery, contributing 0.3 percentage points to the overall growth rate. Investment in facilities also relied heavily on equipment for semiconductor manufacturing, indicating that semiconductors have simultaneously boosted exports, production, investment, and income.
On the other hand, other sectors of the economy remain unstable. While private consumption rose by 0.4%, contributing 0.2 percentage points to growth, this increase was significantly influenced by government support, corporate promotions, and the wealth effect from rising stock prices. It remains to be seen whether this recovery in consumption is based on structural trends of rising employment and wages. Construction investment fell by 0.2% due to sluggish civil engineering, and production in the construction sector decreased by 1.9%. Key industries such as petrochemicals, steel, and automobiles are struggling amid low-cost competition from China and trade pressures from the U.S.
The challenge lies in the fact that the semiconductor boom will not last indefinitely. Semiconductors are a classic cyclical industry. When demand increases and prices rise, companies expand production capacity, but once supply outstrips demand, prices and investments can plummet. Historically, South Korea's economy has experienced simultaneous increases in growth rates and tax revenues during semiconductor booms, only to see exports, investment, and fiscal health falter when the cycle turns. While the current boom in AI semiconductors may last longer than previous cycles, the cyclical nature of the industry remains unchanged.
Moreover, as dependence on semiconductors increases, economic volatility also rises. National growth rates may fluctuate based on semiconductor prices, investment decisions by global tech giants, and the technological rivalry between the U.S. and China. If the improved performance of a few large corporations does not sufficiently benefit small and medium-sized enterprises, local economies, and household incomes, the gap between strong exports and perceived economic conditions will only widen. This is evident in the current situation where, despite the semiconductor boom, manufacturing and youth employment remain sluggish.
The government must not only enjoy the semiconductor boom but also prepare for the next downturn. The current increase in tax revenues and strong exports should be utilized as time and resources for industrial restructuring. It is essential to broaden growth engines into areas such as AI, biotechnology, future vehicles, robotics, secondary batteries, and shipbuilding and defense, while also accelerating the transition to high value-added production in existing industries like petrochemicals and steel. Enhancing productivity in the service sector to create a job base that can absorb shocks to manufacturing is also crucial.
Within the semiconductor industry, it is important to move beyond a memory-centric structure and simultaneously develop competitiveness in system semiconductors, materials, components, equipment, design, and packaging. Achieving results concentrated in specific items and companies must spread throughout the industrial ecosystem for the semiconductor boom to translate into national competitiveness. Research and development, talent cultivation, and the expansion of power, water, and transmission networks should be pursued under long-term plans that remain stable regardless of economic conditions.
The 0.6% growth in the second quarter is undoubtedly good news. However, it is crucial not to mistake the growth supported by semiconductors for a broader economic recovery. Booms eventually come to an end. It is essential to establish a foundation for industries, domestic demand, and employment that can sustain growth even after the semiconductor cycle declines. The true strength of an economy lies not in how high a single industry can rise, but in how well the entire nation can withstand its decline.
