AI boom sustains S. Korea's growth despite global headwinds: IMF official

South Korea is growing because the AI boom is creating powerful demand for semiconductors. That demand has helped the country withstand trade tensions, the Middle East crisis, and the Russia-Ukraine war. The IMF therefore revised its 2026 growth forecast upward.

The main mechanism is stronger semiconductor exports. Companies investing in AI need data centers, chips, and related equipment. South Korea benefits when its semiconductor industry supplies that expanding infrastructure market. The IMF also expects AI investment to continue because data centers take years to build.

This strength does not remove the risks. A weaker AI boom could hurt South Korea’s stock market, current account, and businesses. For now, however, IMF official Choi Ji-young says investment is likely to continue for a long time. The AI cycle has also expanded South Korea’s fiscal room for future growth investment.

The IMF’s new forecast puts South Korea’s 2026 economic growth at 3.3 percent. That is a substantial upgrade from its earlier projection and signals that the country is performing better than expected despite global uncertainty.

The IMF raised the forecast by 0.7 percentage point from its July projection. It linked the change to strong semiconductor exports. Those exports are benefiting from intense demand for AI infrastructure, which includes major data-center and technology investments.

The upgrade matters because the global backdrop remains difficult. Trade tensions, the Middle East crisis, and the war between Russia and Ukraine are weighing on the world economy. Even so, the IMF believes South Korea’s technology-driven export strength is more than offsetting the fallout from the Middle East war. Choi also said the forecast may be conservative because it may not fully include future growth policies.

AI infrastructure is the collection of physical systems that lets AI applications operate. It includes data centers, advanced chips, power and computing equipment, networks, and related facilities. These systems matter because AI investment cannot expand without places and machines to process and store enormous amounts of data.

The article highlights data centers as a central example. Building them can take around 10 years, according to Choi Ji-young. They require large, long-term projects involving specialized equipment and semiconductor supplies. This creates sustained demand for companies making chips and other infrastructure components.

The investment cycle is therefore unlikely to disappear within just a few years. Projects that take a decade to build would not normally be abandoned quickly without making major spending meaningless. The IMF expects AI investment to continue for a long time, although it also warns that a sudden faltering of the boom could create economic risks.

AI infrastructure depends heavily on semiconductors. Data centers and related systems need chips to perform computing, store information, and support AI workloads. As companies build more AI capacity, they purchase more of these components from semiconductor producers.

The article connects this mechanism directly to South Korea. Strong AI infrastructure demand is driving strong semiconductor exports, which more than offset the fallout from the Middle East war. In other words, global AI investment is creating an export channel for South Korean technology manufacturers.

This demand is also supported by the long construction timeline for data centers. Choi said building them can take around 10 years, making the projects unlikely to falter within a couple of years. That helps explain why the IMF expects the technology investment cycle to remain strong in the near term, while still recognizing that a weaker AI boom could hurt the wider economy.

If AI investment falters, South Korea could lose an important source of growth. The IMF specifically warns of a stock-market correction, an adjustment in the current account, and adverse effects on businesses. These outcomes would reflect weaker expectations, reduced exports, and less technology spending.

The mechanism begins with investment. AI data centers and related infrastructure currently support semiconductor demand and exports. If projects are delayed or canceled, chip orders could weaken. Businesses connected to the AI supply chain could then face lower revenue, while investors might reassess company values and trigger a market correction.

The risks are serious, but the IMF does not expect the boom to falter soon. Choi said data-center construction can take around 10 years, and the organization expects AI investment to continue for a long time. The warning remains important because current strength could expose South Korea to a sharper adjustment later.

The Future Fund is a government plan to use windfall revenue from the chip supercycle for long-term growth. Its purpose is to lay groundwork for future economic expansion rather than treating the extra revenue as a short-lived gain. The IMF views the fund’s structure positively.

The proposed mechanism is straightforward. Strong chip exports generate more revenue, and the government channels that windfall into a dedicated investment effort. Such spending could support innovation and strengthen South Korea’s growth potential. Choi also said the AI boom has expanded the country’s fiscal room to invest more in future growth.

The fund is planned for launch next year, but the IMF has not yet provided a detailed assessment. Choi added that the latest growth forecast may be conservative because it does not fully reflect policies aimed at boosting growth. The fund could therefore become an additional source of future economic support.

GDP, or gross domestic product, measures the value of goods and services produced in an economy over a period. The current account records a country’s trade in goods and services plus certain income and transfers with the rest of the world. The debt-to-GDP ratio compares government debt with annual economic output.

These measures answer different questions. GDP shows whether the economy is expanding. The current account indicates whether external trade and income bring in more funds than they send out. The debt-to-GDP ratio shows the size of government debt relative to the economy that supports public finances. Together, they provide a broad economic picture.

The article discusses all three in South Korea’s context. The IMF raised its growth forecast, warned of a possible current-account adjustment if AI weakens, and advised growth economies not to focus excessively on debt-to-GDP ratios. It recommended prioritizing innovation and investment in growth potential.
