Semiconductors made up 41.5% of everything South Korea exported in July. It was the country's second-biggest export month on record. So why did its stock market fall 22%?

Semiconductors made up 41.5% of everything South Korea exported in July. It was the country's second-biggest export month on record. So why did its stock market fall 22%?

Key points

  • South Korea exported $98.89 billion of goods in July, up 62.8% from a year earlier. It is the second-biggest month in the country's history, behind June's $102.25 billion.
  • Semiconductors were $41.01 billion of that, up 178.8%, also second only to June and the second straight month above $40 billion.
  • Chips were 41.5% of everything Korea sold abroad, and close to 69% of the entire increase over last July.
  • The trade surplus was $30.32 billion, an 18th straight month in surplus. Home appliances were the only one of the 20 main export categories to fall.
  • The Kospi fell 22.19% in July, the largest monthly drop of any major world index, after rising 101.14% in the first half of the year.

On August 1, the Ministry of Trade, Industry and Energy (산업통상자원부) reported that South Korea exported $98.89 billion of goods in July, up 62.8% from the same month a year earlier. It's the second-biggest export month the country has ever recorded. The biggest was June, at $102.25 billion, the first time Korea had passed $100 billion in a single month.

In the same 31 days, the Kospi fell 22.19%, the largest monthly drop of any major stock index in the world.

Both of those describe the same country over the same stretch of days. The factories had close to their best month on record while the market that's supposed to say what those factories are worth had one of its worst.

What the chips did

Semiconductors came to $41.01 billion, up 178.8% from last July. That's the second-highest month on record for chips, behind June's $44.8 billion, and the second month in a row above $40 billion. The ministry credits a rebound in fixed DRAM contract prices and continued strength in high-value memory, which mostly means HBM, the stacked memory that Samsung Electronics and SK Hynix make for AI servers.

Two numbers show how much of Korea's trade now rests on that one industry. Chips were 41.5% of all exports in July. And of the increase over last July, an increase of about $38.1 billion, semiconductors were close to 69% of it.

Daily average exports were $4.12 billion, up 69.6%. Imports came to $68.56 billion, up 26.5%, leaving a surplus of $30.32 billion. That is the 18th month in a row Korea has sold more than it bought.

What the minister called diversified

Trade Minister Kim Jung-gwan read the month as a broad win rather than a narrow one, and brought numbers to the argument.

"July exports recorded a high performance in the 90 billion dollar range despite it being the start of a half year," Kim said. "With the strength in semiconductors continuing, 19 of the 20 main export items increased, and items other than semiconductors also showed a high growth rate of 26%, so exports have diversified on the basis of our products' competitiveness."

That case is stronger than it first looks. Home appliances really were the only one of the 20 main categories to fall, and 26% growth outside of chips is a good number in any year. Computers rose 404.0% to $4.79 billion, wireless communication devices 51.0% to $1.81 billion, ships 46.9% to $3.29 billion. Nothing there is weak.

The sizes are still not close to each other, though. Cars remain the second-largest export category at $6.24 billion and grew 7.0%. Displays rose 2.4%. Chips grew almost seven times faster than everything else put together, and one category now carries four out of every ten dollars the country earns abroad. Both things are true at once, which is why the same table supports the minister's read and a more worried one.

Two categories where the money rose and the goods did not

There's a wrinkle worth pulling out, because it changes what a rising number means. Petrochemical exports rose 10.3% in value while the volume actually shipped fell 9.1%. Petroleum products rose 34.1% in value while volume fell 8.8%.

In both cases Korea sold less and collected more. That's a price effect rather than more demand, and oil has been expensive this summer. It flatters the export total in dollars without meaning anyone abroad is buying more Korean petrochemicals.

Why the market went the other way

July wasn't a normal month in Seoul. The Kospi's 22.19% drop came after a first half in which it rose 101.14%, the best performance of any major index in the world, so a lot of what happened was people selling to keep what they had made on an extraordinary run.

The depth is harder to explain that way. Measured to July 30, before the final session, the month was down 34.01%. That's worse than the Kospi's fall in the 1997 Asian financial crisis at 27.25%, and worse than 2008 at 23.13%. Then the index rose a record 17.91% on July 31 and took back a third of the month's loss in one day. We wrote about that session and about the new rule on leverage funds that started the same morning.

What the trade data settles is a question people argued about all month, which is whether memory demand had already peaked. A 178.8% rise in chip exports isn't what a peak looks like.

Na Jung-hwan, an analyst at NH Investment & Securities (NH투자증권), expects that to keep showing up in company results rather than only in customs data.

"The operating profit level of the semiconductor companies rises step by step each quarter through next year," Na said.

That's a forecast, and forecasts about memory cycles have been wrong before. The July trade figures aren't a forecast. They're goods that already left the ports.

What the ministry is worried about next

Kim closed the announcement on a more careful note than the headline number would suggest.

"Because of new tariff measures under Section 301 of US trade law, stronger protectionism in major countries and uncertainty in the Middle East situation, export conditions are expected to be difficult going forward," Kim said. "We will mobilize all available policy tools so that companies can respond in time to changes in the trade environment."

Notice what the ministry names as the risk for August. Tariffs, protectionism and the Middle East are all questions about whether Korean goods can reach the people who want them. None of them is a question about whether anyone wants them. Korea's problem in July was never that the world stopped buying, and the export data makes that plain.

The concentration is the thing to keep watching. A trade balance resting 41.5% on one product category behaves a lot like a stock index resting on two companies, and Korea has just spent a month learning what that feels like.

Frequently asked questions

How much did South Korea export in July 2026?

$98.89 billion, up 62.8% from July 2025. It is the second-biggest export month in the country's history, behind June 2026's $102.25 billion, which was the first time Korea passed $100 billion in a single month. Imports were $68.56 billion, up 26.5%, leaving a trade surplus of $30.32 billion and an 18th consecutive month in surplus. The Ministry of Trade, Industry and Energy released the figures on August 1, 2026.

How much of Korea's exports are semiconductors?

41.5% in July 2026. Semiconductor exports were $41.01 billion of the $98.89 billion total, up 178.8% from a year earlier. That is the second-highest month on record for chips, behind June's $44.8 billion, and the second straight month above $40 billion. Semiconductors also accounted for close to 69% of the roughly $38.1 billion increase in total exports over July 2025.

Did any Korean export category fall in July 2026?

Home appliances were the only decline among the 20 main export categories. Computers rose 404.0% to $4.79 billion, wireless communication devices 51.0% to $1.81 billion, ships 46.9% to $3.29 billion, cars 7.0% to $6.24 billion and displays 2.4%. Excluding semiconductors, Korea's exports still grew 26%.

Why did the Kospi fall while Korean exports were near a record?

The Kospi fell 22.19% in July 2026, the largest monthly drop of any major world index, after rising 101.14% in the first half of the year, so a large part of the fall was profit-taking on an extraordinary run. Measured to July 30, before the final session, the month was down 34.01%, worse than the 1997 Asian financial crisis at 27.25% and 2008 at 23.13%. The index then rose a record 17.91% on July 31.

Do Korea's July export figures show memory demand peaking?

The data points the other way. Semiconductor exports rose 178.8% year over year, and the ministry credits a rebound in fixed DRAM contract prices along with continued strength in high-value memory such as HBM. Na Jung-hwan of NH Investment & Securities expects semiconductor operating profit to rise step by step each quarter through next year. Two categories are worth reading carefully though, since petrochemical export value rose 10.3% while volume fell 9.1%, and petroleum product value rose 34.1% while volume fell 8.8%, which is a price effect rather than more demand.
