🌏 Exports +68.7% — one product is almost half the total
Korea's August exports hit $98.25bn, chips $46.65bn of it. Also: Japan's 10-year yield at 3% for the first time since 1996, and Vietnam's import cover.
Numbers compiled Tuesday, 1 September 2026, at 4:40 pm in Seoul (UTC+9), a 4-min read. Seoul and Tokyo closes are final; Hong Kong, currency and bond rows are snapshots.
Yesterday's answer: B — because a PMI is a diffusion index: 50 is the even split between firms reporting better and worse, so a reading that rises but stays under 50 means manufacturing is shrinking in fewer places, not that output grew.
Korea sold $98.25 billion of goods abroad in August, 68.7% more than a year earlier, and $46.65 billion of it, 47.5%, was semiconductors. The KOSPI added 0.23%. In Tokyo, the government's ten-year borrowing cost touched 3% for the first time since 1996. Today's lesson is how to read a growth rate that is really two growth rates wearing one number.
📊 The Dashboard — Tuesday, 1 September 2026
| Gauge | Level | Move | What this means |
|---|---|---|---|
| KOSPI (South Korea) | 6,835.80 | 🟢 ▲ +0.23% | Closed, final: Google Finance, Investing.com. Opened lower on oil and US yields, Samsung down 1.83% and SK hynix 1.08% at 9:12 am, traded a 6,732 to 6,857 range, closed up. A quiet day by this month's standards. |
| KOSDAQ (South Korea, rotation row) | 821.25 | 🔴 ▼ −1.56% | Closed: Investing.com. The big board rose and the small-cap board fell: the export number flatters the exporters, not everyone. |
| Nikkei 225 (Japan) | 66,215.34 | 🔴 ▼ −0.15% | Closed, final: Google Finance, Yahoo Finance. The low was 65,576.61, 1.1% down; most of the fall was bought back. A flat index on a day the bond market made history. |
| Hang Seng (Hong Kong) | ≈25,334 | 🔴 ▼ ≈ −0.9% | Still trading at compile: Google Finance, 3:15 pm (−0.84%), Investing.com (−0.91%). A snapshot. Shein fell about 10% below its offer price on its first day. |
| USD/KRW | 1,370.4 | 🔴 ▲ won weaker | Seoul's 3:30 pm close, 1.8 won weaker. A record surplus and a weaker won on the same day; the Spotlight explains why that is normal. |
| USD/JPY | ≈159.96 | 🔴 ▲ yen weaker | Snapshot: Google Finance, from 159.75. Still under 160, the level where Tokyo acted in July. Finance Minister Katayama said "orderly JPY movement is critical". |
| JGB 10-year yield (Japan) | ≈2.99% | 🔴 ▲ +5 bp | Snapshot: 2.993% at compile, from 2.941%, after touching 3.001%. The first 3% print since September 1996. It was half this level a year ago. |
What happened, in plain words
Two big numbers, one from each side of the Sea of Japan. In Seoul, the trade ministry said exports rose for a 15th straight month and beat the 62.6% economists expected; imports rose 22.6% to $63.51 billion, leaving a $34.75 billion surplus. The same morning the government proposed a record 820.9 trillion won budget for 2027, up 12.8%, paid for by tax revenue that is projected to jump 49.8% on the chip boom. In Tokyo, the ten-year yield crossed 3% as investors priced a Bank of Japan hike on 18 September and a bigger-spending government. And in the background, Brent crude rose 3.7% to about $91.7 on the collapse of the US-Iran ceasefire framework, while futures put the odds of a September Fed rate rise at 66%. Dearer oil and dearer dollars are why Asia's equity boards barely moved on Korea's best export month ever.
🌏 The SEA watch — this week's number: Vietnam's import cover
The rotation returns to Ho Chi Minh City, where the exchange is shut until Thursday for National Day; the VN-Index went into the holiday at 1,832, its seventh straight gain. The gauge to learn is import cover: a country's foreign-exchange reserves divided by what it spends on imports each month. It answers one question: if the dollars stopped arriving, how many months could the country keep buying what it needs? The old rule of thumb is at least three months. Vietnam's reserves were about $87.6 billion in June, while imports ran $340 billion in the first seven months of the year, about $48 billion a month, and one Vietnamese economist put cover at "only 1.9-2 months of imports". Why it belongs in a 1997 lens: Thailand's reserves looked fine until the market tested them. Two caveats keep this descriptive. Most of Vietnam's imports are inputs for factories that re-export, so the dollars come back; and the same economist calls the deficit no short-term concern. The number says how thin the cushion is, not what happens next. We describe; we don't call.
⭐ Spotlight: $34.75 billion — what a trade surplus does to a currency, and when
A trade surplus is dollars earned abroad that exceed dollars spent abroad. Exporters eventually sell those dollars for won to pay wages, suppliers and taxes, so a surplus is a steady buyer of the won. That is why yesterday's month-end dollar selling pushed the won firmer. But "eventually" is the word. The surplus arrives over weeks as companies choose when to convert; today's price was set by faster money: an oil bill that just got 3.7% dearer and a two-in-three chance of a US rate rise, both of which buy dollars now. So the surplus and the weaker won can share a day without contradiction. Read a surplus as a tide and the daily rate as the waves on top of it.
📈 Chart of the Day — one number, two speeds
How to read this: a headline growth rate is a weighted average of its parts, so before you repeat it, ask what share each part has and how fast each grew. Chips are 47.5% of exports and rose 209%; the trade minister said non-chip exports grew 20%. Work the ministry's rates backwards and chips were about $15 billion a year ago, everything else about $43 billion: roughly four fifths of the $40 billion increase came from one product. The 68.7% is true, and it describes almost nobody: most of Korea's exporters grew at about 20%, and car exports fell 29.8%. When one part dominates, read the part, not the average.
📅 Tomorrow
Wednesday 8 am Seoul: Korea's August consumer prices. Forecasts have inflation back above 3% after July's 2.8%, partly because last August's mobile-fee discounts drop out of the comparison. Watch the JGB row too: the Bank of Japan decides on 18 September. Related reading: what the Bank of Korea's dot plot says about the next move.
One question. Today's chart showed exports up 68.7%, with chips up 209% and everything else up 20%. Which reading is right? A: Most of Korea's exporters grew their sales by about 69%. B: The headline is an average; one product with almost half the total drove most of the increase, and the rest grew about 20%. C: Non-chip exports must have fallen, because chips tripled.
