South Korea's Exports Jump 45.3% in Early August to a Record High, With Semiconductors Now Nearly Half of All Shipments

South Korea's exports got off to a record start in August 2026. According to preliminary data the Korea Customs Service released on August 11, the country shipped $21.3 billion worth of goods abroad in the first 10 days of the month — a 45.3% jump from the same period a year earlier, and the strongest first-10-days-of-August performance on record, easily surpassing the previous high of $15.6 billion set in August 2022.

The engine behind the surge was unmistakable: semiconductors. Chip exports rose 155.4% year-on-year to $9.95 billion, itself a record for the period, as global demand for AI-related processors and memory chips kept climbing. Semiconductors alone made up 46.8% of everything South Korea exported in those 10 days, a share that has jumped more than 20 percentage points in a single year.

Imports grew too, but more slowly — up 23.1% to $19.5 billion — leaving the country with a trade surplus of $1.8 billion for the period. Because the figures cover only the first third of August and haven't been seasonally adjusted, they're best read as an early signal rather than a final verdict on the month, but they extend a run of outsized export growth that has lasted several months.

A Record Start to August

South Korea's exports reached $21.3 billion in the first 10 days of August 2026, according to preliminary trade figures published by the Korea Customs Service on August 11. That marks a 45.3% increase over the same 10-day window in August 2025, and it is the strongest performance ever recorded for the first third of August, surpassing the previous record of $15.6 billion set in August 2022 by a wide margin. Imports over the same period rose 23.1% year-on-year to $19.5 billion, resulting in a trade surplus of $1.8 billion.

Semiconductors Do the Heavy Lifting

The standout figure within the release is semiconductors. Chip exports climbed 155.4% from a year earlier to reach $9.95 billion in the first 10 days of August — also a record for the period. That pushed semiconductors' share of total exports to 46.8%, up 20.1 percentage points from the same period last year, meaning nearly half of everything South Korea shipped abroad in early August was a semiconductor product. The scale of the increase is consistent with continued strong global demand for the high-bandwidth memory and logic chips used in AI data centers and accelerators, an area where South Korean manufacturers hold significant global production capacity.

A Preliminary, 10-Day Snapshot

It's worth being precise about what this data does and doesn't show. The Korea Customs Service release covers only the first 10 calendar days of August and is explicitly labeled preliminary; it is not seasonally adjusted and does not represent a full-month total. Early-month trade figures can also be affected by the timing of shipments and customs clearances relative to the same period a year earlier, which can exaggerate or understate year-on-year growth rates compared with a full month. The Korea Customs Service typically publishes a fuller mid-month update around the 20th of each month, followed by complete monthly figures in the first days of the following month.

Part of a Longer Run of Export Strength

The early-August reading extends a stretch of unusually strong export growth for South Korea, which has posted repeated large year-on-year gains in semiconductor shipments over recent months as AI-related demand has stayed elevated. Whether the 45.3% pace holds once the full month's data is in will depend partly on how shipments in the remaining three weeks of August compare with the equivalent period last year, and partly on how much of the early surge reflects pulled-forward orders rather than a durable step up in demand.

Reader Q&A

Is $21.3 billion South Korea's total exports for all of August 2026?

No. This figure covers only the first 10 calendar days of the month (August 1–10) and is explicitly labeled preliminary by the Korea Customs Service. The complete monthly total won't be available until early September.

Why did semiconductor exports grow so much faster than overall exports?

Semiconductor exports rose 155.4% year-on-year, more than three times the 45.3% growth rate for total exports, reflecting concentrated global demand for AI-related chips. Because semiconductors already made up a large share of South Korea's exports, this uneven growth pushed their share of the total up by more than 20 percentage points in a single year.

Does this mean South Korea's overall trade is booming across all sectors?

The Korea Customs Service's preliminary release doesn't break down performance by sector beyond semiconductors, so it isn't possible from this data alone to say growth is broad-based rather than concentrated. Given that semiconductors already account for nearly half of exports and grew far faster than the total, a significant share of the overall gain likely traces back to chips specifically.

How does this compare with the prior record for early August?

The $21.3 billion figure surpasses the previous record for the August 1–10 period, $15.6 billion, set in August 2022 — an increase of more than $5.6 billion, or roughly 37%, over that previous high.

Why can early-month trade figures look more dramatic than the full month turns out to be?

Early-month data can be skewed by the timing of shipments and customs clearances relative to the same days a year earlier — a handful of large shipments falling just inside or outside the 10-day window can move the year-on-year percentage substantially. That's why the Korea Customs Service labels the release preliminary and typically issues a mid-month and then a full-month update.
