The Gust That Lasted All Day
The gust lasted all day and still did not stop.
Even as the sun sets, we watch from the same place.
Today's 12:00 flash report is now in its final closing edition. It incorporates final closing flows and margin-loan figures separated by market, released after the close.
Final Closing Figures
Retail Investors Absorbed KRW 4.3tn
View table
| Market | Retail investors | Foreign investors | Institutions |
|---|---|---|---|
| KOSPI | +43,179 | -49,841 | +6,386 |
| KOSDAQ | +499 | +869 | -1,339 |
Of institutions' +KRW 638.6bn net buying, pension funds accounted for only KRW 116.5bn. The rest is closer to the balance left after financial investment firms, investment trusts, and others offset each other. The institutional net total alone looks like directional buying, but broken down by investor type, neither benchmark tracking nor bargain buying has yet reached scale. On KOSDAQ, institutions net-sold −KRW 133.9bn, including −KRW 107.8bn from investment trusts.
How Much Debt Has Been Cleared?
The difference in declines is 24%p, leaving much more room for KOSPI to deleverage.

Note: Why low markers sit on peaks: indices can fall sharply in a day, while margin liquidation lags by several days, so intensity peaks on the day the index bottoms. In 2020, it reached 0.948 on 3/19, then fell to 0.598 after 8 trading days (−36.9%). The same structure applies today: the one-day rise from 0.903 on 7/27 to 0.978 happened because the index collapsed 7.72%, not because debt rose.

| 2016-12-05 rangebound market | 575 | 3.75tn | 0.653 |

| 2022-10-13 tightening bear | 652 | 7.62tn | 1.170 |
This number reads "the index has just collapsed," not "debt is heavy". Historically, intensity also peaked on the index-low day, then fell sharply as margin liquidation followed several days later (in 2020, 0.95 on 3/19 → 0.60 after 12 days). Not a single line of forced liquidation from today's −7.72% is reflected yet. 7/27 was actually a rebound day, when KOSPI margin loans grew KRW 85.5bn. The real figures arrive 7/30~31.
There Were Four Triggers, Not Three
NVIDIA -4.99% · AMD -5.17% · SK hynix ADR -7.47%. Nasdaq fell for 4 consecutive trading days, while the Dow gained +0.51% — a market that singled out semiconductors.
7/27 Shanghai STAR debut. Opening price: +452%; reported closing price: +466~476%. The narrative that the proceeds would fund memory expansion was priced in alongside its No. 1 A-share market cap.
ASML's monopoly territory — deliveries to SMIC, Hua Hong, and CXMT planned this year, ASML −6%. But at 5 units a year with subpar performance, this is less a volume shock than the pricing of a narrative of eventual self-sufficiency. It directly triggered the −11–13% fall in KOSDAQ equipment stocks.
This, not China, is the main cause of today's US decline. Reports that NVIDIA is considering a $250bn backstop for OpenAI's data-center usage raised concerns about circular AI financing: is the chip seller financing its buyer?
This is a different kind of risk — while ①–③ concern competition, ④ concerns funding. The narrative has started to fray from two directions at once.
This Is Not Risk-Off
Oil −8.7%, US 10-year Treasury yield 4.639% (−4bp), dollar index 101.5. Falling oil + falling yields + a weak dollar is normally favorable for emerging markets. Korea missed all those benefits because of semiconductors. Korea's problem is portfolio concentration, not global macro. At its July 8 meeting, the government said greater semiconductor weight was increasing volatility. 3 weeks later, events confirmed it.
Oil Bought Easing Tensions. The Strait Is Still Closed.
At a July 27 briefing, Iran's foreign-ministry spokesperson said "the Strait of Hormuz remains closed" (translated). That has not changed since the July 11 declaration of an indefinite blockade. At the same briefing: "we are not currently in any negotiations with the United States" (translated). On the same day, President Trump said Iran wanted to meet and they were meeting. The two sides' statements directly contradict each other. What is actually underway is bilateral Iran–Oman talks, which Iran explicitly said were unrelated to the US.
On top of that, a tanker exploded near Hormuz on July 26. Iran's explanation: it contacted a naval mine after leaving the designated route — mines are still there.
Prices have bought a half-probability of easing on just one headline: a halt to US air strikes. If oil rebounds, Korea faces another headwind.
The Government Tightened Rather Than Propped Up
An individual limit of around 20% of total investments was discussed. From July 31, the minimum deposit rises to at least KRW 30 million in cash — confirmed implementation, not a proposal. There was no mention of a market stabilization fund or short selling..
The only measures from the financial-market review chaired by the deputy prime minister 3 weeks ago were 24-hour FX trading, a won-internationalization roadmap, and adjustments to government-bond issuance. There were 0 stock-market stimulus measures. The diagnosis was "profit-taking and rebalancing sales." Today's −10.84% did not change that stance. The government does not see this decline as something to rescue.
The constraints are clear too: on 7/16, the BOK raised rates to 2.75% (the first change of direction in 3 years and 6 months), clashing directly with liquidity measures. With USD/KRW high at 1,462.5, easing liquidity would pressure the exchange rate. The June 3 local elections are over, and the next nationwide election is in 2028, putting political urgency at its lowest.
Forced liquidation is already surging — from KRW 56.5bn in January to KRW 393.5bn in June (+596%), across 21,615 accounts (+47% on the previous month). The average per account rose from KRW 9.32 million to KRW 18.2 million. For those aged 70 and above, KRW 1.8bn rose to KRW 16.3bn (+791%), the No. 1 growth rate. But all these figures run only through June. The forced liquidations from today's −10.84% appear on July 30–31.
Then The minimum-deposit increase takes effect on that same July 31.
Forced sales and a barrier to new entry arrive on the same day — for the very retail investors who absorbed KRW 4.3tn today.
Three Days Starting Tomorrow: All Tests
09:00
Watch three comments, not the headline numbers — ①capex guidance (half the rationale for KOSDAQ equipment stocks' −13% fall rests here); ②commodity DRAM prices (whether CXMT competition is absorbed); ③70% revenue share from AI data centers (KB forecast) — this third point is exactly the same vulnerability as tonight's circular-financing concern in New York. The more concentrated the customers, the more their funding structure becomes SK hynix's risk. The better the numbers, the bigger the question: whose money is generating these profits?
03:00
Then Around the 8/3 return is a window for "trip outcomes + stock-market measures" to appear together.
Put today's four together, and one sentence emerges: Oil, the semiconductor narrative, the sustainability of SK hynix's profits, and retail investors' buying power are all in the same state: prices have moved; physical conditions have not yet delivered a verdict. Those verdicts all arrive this week.
Gusts change direction, not terrain. In three days, we will know what was terrain.
