Rio Times · Asia Intelligence Brief August 7
—Korea’s reversal The Kospi was up 1.83% nine minutes after the open and closed down 0.60% at 6,258.77.
—A specification review SK Hynix fell 4.88% to 1,422,000 won, still weighed down by a report that Nvidia is testing less memory in its next processor.
—China’s exports July exports rose 23.9% from a year earlier, beating forecasts of 22.2%, with a trade surplus of 112.5 billion dollars.
—Indonesia rises Jakarta’s index closed up 1.04% at 6,409.65, after the economy grew 5.29% in the second quarter.
—Japan’s earnings day Some 679 companies reported results, and the Nikkei still slipped 76.55 points to 65,606.71.

One supplies the artificial-intelligence boom and flinches at every American memo, and the other is not in that trade at all.
South Korea – Nine Minutes of Confidence
A rally that did not survive the morning
Korea’s Kospi opened 1.09% higher at 6,365.07 and by nine minutes past nine it was up 1.83%, back above 6,400, with foreign investors buying. It closed down 0.60% at 6,258.77.
The junior Kosdaq slipped 0.36% to 798.81. Foreign investors ended the day net sellers of 862.4 billion won, having begun it as buyers.
Undone by a memo about a specification
The cause was narrow and telling. SK Hynix fell 4.88% to 1,422,000 won, still weighed down by a report from earlier in the week that Nvidia has tested versions of its next-generation Rubin Ultra processor carrying less memory than it originally announced.
Samsung Electronics, by contrast, closed up 0.22% at 231,000 won, splitting from its rival for the first time this week. Naver dropped 7.08% after reporting operating profit slightly below last year’s.
Not everyone shares the gloom, with Goldman Sachs keeping a positive view on memory and pointing to a shortage that could run to 2030. The exchange is acting on the volatility too, introducing after-hours trading in exchange-traded funds from 14 September, with leveraged products excluded.
China – The Ports Answer the Question
Exports beat expectations again
Chinese exports rose 23.9% in July from a year earlier, ahead of the 22.2% economists had forecast, though slower than June’s 27% surge. Imports climbed 27.5%, and the trade surplus came in at 112.5 billion dollars against expectations nearer 107 billion.
Typhoon disruption to port operations slowed the month’s flows. Even so, the figures beat forecasts on both sides of the ledger.
Strength that doubles as a grievance
What is filling those ships is the same thing frightening Seoul, namely the worldwide build-out of artificial-intelligence infrastructure. Demand for high-tech electronics, vehicles and green technology is absorbing Chinese output faster than anyone expected.
The national mood is a settled confidence with a barb in it. Beijing’s surplus passed a trillion dollars last year, and that number is precisely what Washington and Brussels keep asking it to give up.
Indonesia – The Other Asia
Up while the north fell
Jakarta’s index closed 1.04% higher at 6,409.65, adding almost 66 points on the day North Asia gave back its gains. Ten sectors rose, led by infrastructure at 2.17% and technology at 1.25%.
Some 355 shares advanced against 235 declines, on turnover of 16.06 trillion rupiah. The telecoms group Indosat led the gainers among the largest listed companies.
Growth made at home
The economy grew 5.29% in the second quarter, and the government is preparing a stimulus package worth 26.34 trillion rupiah covering social assistance, transport, tourism and fuel-price stability. The tax take has improved too, rising to 9.32% of output from 8.42% a year earlier.
Indonesia’s temper here is unhurried and domestic, a country whose growth does not depend on anyone else’s product roadmap. Investors are waiting on the naming of a new central bank governor, expected this week.
Japan – Six Hundred and Seventy-Nine Sets of Numbers
An earnings deluge, barely felt
Some 679 Japanese companies reported results on Friday, among them Fujikura, Kawasaki Heavy Industries, Recruit, Olympus and Japan Post. The Nikkei still finished down 76.55 points at 65,606.71, a second consecutive small decline.
The spread was wide, with Fujikura guiding to a 58.4% rise in recurring profit and Olympus to 48.9%, while Obayashi and Infroneer pointed lower. Chip-related shares were soft through the morning and steadied late.
Two stocks did most of the damage
SoftBank Group reported first-quarter net profit of 347.3 billion yen, down 17.7% from a year earlier as costs rose at its British chip designer Arm. Its shares fell more than 2% on Friday, after dropping over 4% the previous day ahead of the results.
Together with the testing-equipment maker Advantest, that single pair pulled roughly 293 points off the index. It is diligence without much resonance, a market where hundreds of companies report and two of them set the direction.
Korea’s market gave up a 1.8% rally because an American company is testing a chip with less memory in it, while Indonesia rose 1% on growth it generates itself — the clearest picture yet of an Asia split between those who supply the boom and those who simply grow.
Vietnam – Eight Percent and a Five-Year High
Factories running hot
Vietnam’s economy expanded 8.18% in the first half of the year, with the second quarter at 8.39%. July industrial production rose 14.5% from a year earlier and manufacturing 15.0%, while realised foreign investment reached a five-year high.
The stock market edged up 0.19% to 1,768 on Friday. It is still 11.55% higher than a year ago, despite slipping over the past month.
Ambition turned to delivery
The government plans to spend the equivalent of a tenth of national output on infrastructure between now and 2030. Roughly 60 billion dollars is earmarked for airports, railways and power.
Hanoi’s mood is impatient in a productive way, having shifted the argument from setting targets to meeting them. Growth of that order is rare enough anywhere to be worth watching closely.
Taiwan – A Market Inside One Company
Concentration as a national condition
Taiwan’s benchmark index carries a risk no other market in the region does. The chipmaker TSMC alone accounts for more than 40% of its total value.
When global chip sentiment turns, Taipei does not wobble so much as tilt. There is no domestic sector large enough to offset it.
The sharpest version of the week’s lesson
That makes Taiwan the purest example of the supplier’s position. Its prosperity is real, and the decisions that set it are taken elsewhere.
It is the same exposure Korea felt on Friday, only more so. Being indispensable is not the same as being in control.
The Bigger Picture
Friday split the region cleanly in two. Korea, Japan and Taiwan supply the artificial-intelligence build-out and spent the day reacting to decisions made in California, with Seoul losing a 1.8% rally over a report that Nvidia may fit less memory into its next processor.
Indonesia and Vietnam are barely in that trade and had the better day, one closing up 1.04% on 5.29% growth and the other running above 8% with factory output up 14.5%. Their strength comes from consumers, construction and public investment rather than from anyone’s order book.
China sits between the two, its ports filling precisely because the boom is real, its surplus of 112.5 billion dollars in a single month the very thing its trading partners want reduced. Being essential to the world economy turns out to be a complicated position to hold.
