The International Monetary Fund has raised its 2025 growth forecast for South Korea to 3.3 percent, citing an AI-driven semiconductor boom as the main engine of the upgrade, the Hankyoreh reports.

Chips remain the backbone of Korean exports. Samsung Electronics and SK Hynix supply the memory that sits inside nearly every AI data center build-out, and HBM demand in particular has shifted from cyclical surplus to structural shortage. The IMF revision reflects that shift in commercial terms: the fund now expects semiconductor exports to carry a larger share of nominal GDP growth than it previously assumed.

An upgrade of this kind carries weight. The IMF does not revise national forecasts on sentiment; it revises them when trade data, order books and pricing argue for it. In Korea's case, memory pricing and AI accelerator demand have done the arguing.

What does the revision change?

For policymakers in Seoul, a 3.3 percent outlook eases pressure on stimulus and gives the Bank of Korea room to weigh inflation against export strength. For the industry, it confirms that AI capital spending — concentrated in hyperscaler data centers — has become a macroeconomic variable for Korea, not merely a sector story.

The effect is not evenly spread. Semiconductor strength lifts equipment makers, materials suppliers and logistics along with the two memory giants. The rest of the economy — construction, domestic consumption — receives a thinner benefit.

How durable is the chip-driven uplift?

The forecast rests on AI demand persisting through the year. Memory markets have reversed direction before, and the IMF's number assumes the current build-out continues rather than pausing. Any slowdown in hyperscaler capital expenditure would feed through to Korean export figures within a quarter or two.

For now, the fund's economists are betting on continuity. Korea's growth profile, in their view, now moves with the AI cycle — and the AI cycle is still climbing.
