South Korea’s semiconductor exports have been a powerful engine for Asia’s fourth-largest economy, helping push total exports to a record last month. But the sheer speed of the chip boom is raising questions about how durable that growth really is.
Semiconductor exports jumped 209% from a year earlier to a record $46.65 billion in August, accounting for 47.5% of the country’s $98.25 billion in total goods exports that month, according to data released this week by the Ministry of Trade, Industry and Resources. The surge was driven largely by AI infrastructure spending, as major cloud providers including Google and Amazon expanded their capital outlays.
The numbers are striking — but perhaps too striking, some analysts warn. If the boom fades, what takes its place?
‘Two speeds’ economy
Jeff Ng, head of Asia macro strategy at Sumitomo Mitsui Banking Corporation, estimated that semiconductors accounted for nearly 80% of export growth in August. “Overall export growth was driven by chips, computers, and higher petroleum product prices,” he told CNBC.
While rapid growth is generally a positive sign, the pace also creates risk. A gradual slowdown could be manageable, said Dave Chia, an economist at Moody’s Analytics. “An abrupt stall is a different matter, because the economy already runs at two speeds, and the sectors that would need to take up the slack are the ones under pressure today.”
Monetary policy could also reduce the cushion if the cycle turns soon. The Bank of Korea raised its base rate to 3% in August — its second straight hike — as core inflation remained elevated. Chia warned that if chip demand cools while policy is still tightening, “the windfall fades when domestic demand isn’t strong enough to take over.”
Weak spots beyond chips
Other traditional export sectors are struggling. Automobile exports fell 29.8% year over year in August, though the trade ministry attributed much of the drop to summer-holiday timing and partial strikes. But Chia said more persistent headwinds, such as U.S. tariffs and a shift toward production in American plants, also weigh on the sector.
Still, the picture is not uniformly bleak. The Bank of Korea said in its August policy statement that the recovery in consumption is gradually accelerating. And the trade ministry’s data showed non-semiconductor exports rose 20% in August.
Homin Lee, senior macro strategist at Swiss private bank Lombard Odier, said that if semiconductor momentum faded while other cyclical sectors performed well, South Korea could still sustain annual real growth of around 2% to 3%.
Lee acknowledged the exceptional nature of the current semiconductor and tech export boom but stopped short of calling it “over-reliance.” The country has other cyclical sectors that tend to do well when the global economy performs well, he noted.
Near-term outlook
Analysts’ base cases remain positive for now. Ng expects overall export growth to stay positive over the next 12 months, although it could moderate due to base effects and stabilizing prices.
The challenge for policymakers will be managing the transition if the boom loses steam — ideally gradually, rather than all at once.
