Seoul's first session after the jobs shock — a Monday morning checklist
KOSPI gives its first response Monday to the US jobs shock and record rally — watch chips, the won, and rotation
The three lines
- Friday's US close left two signals at once: payrolls fell, indexes hit records
- Monday's watch list: foreign chip flows, the dollar-won rate, growth-stock rotation
- A checklist, not a forecast — what each signal would mean, mapped in advance
Key questions
- US records on Friday — so KOSPI rises Monday?
- Not automatically. The US rally was driven by rate-cut hopes, but the cause of those hopes was shrinking employment. KOSPI must price both: cut expectations (positive) and a cooling US economy that buys Korean exports (negative). Foreign investors sold ₩856bn of Seoul shares on Friday — whether that reverses is the real question.
- What exactly should be watched
- Three things. Foreign flows in Samsung Electronics and SK Hynix — the trend-setter for the index. The dollar-won rate — dollar weakness from cut bets would support foreign buying if it holds. And rotation — whether rate-sensitive growth names lead instead of chips, signaling a 'rates trade' has opened in Seoul.
- What else is on this week's calendar
- Domestically: the ruling party's Honam primary voting (Aug 11-14), a possible housing-supply announcement, and the power-demand peak week. Abroad: US inflation prints on the road to Jackson Hole (Aug 27-29). Markets now treat a September cut as given and argue about size and pace.
Markets were closed all weekend; the material kept piling up. Friday night in New York left two headlines that point in opposite directions — "America lost jobs" and "record closes" — and at 9am Monday, Seoul translates that contradiction into a price for the first time. This piece is a checklist, not a forecast: which signals to watch, and what each would mean, mapped before the open.
1. The setup — two Americas for KOSPI to digest
Monday's inputs cut both ways. The bullish channel: a September Fed cut is now near-fully priced, dragging Treasury yields and the dollar lower — historically supportive conditions for emerging-market equity flows. The bearish channel: the reason for the cuts is a shrinking US labor market, which clouds demand for Korean exports — semiconductors above all. That reading would extend Friday's foreign selling (₩856bn net) rather than reverse it.
The same material was read bullishly by Wall Street (Nasdaq +1.3%, record). Whether Seoul adopts the same reading is Monday's question — and the answer will be written in the order flow, not the index level.
2. The checklist — three signals and their meanings
| Signal | Where to look | How to read it |
|---|---|---|
| ① Foreign chip flows | Net foreign buying in Samsung, SK Hynix | A turn to buying = the rate-cut reading wins |
| ② Dollar-won | Holding/extending the 1,410s | Won strength supports foreign inflows |
| ③ Rotation | Bio/growth vs chips relative strength | Growth leading = a rates trade has opened |
| Supporting | KOSDAQ reclaiming 800 | Risk-appetite thermometer |
| Warning | Index up while foreigners keep selling | A rally with shallow foundations |
The trunk is ①. All last week, KOSPI ran on a split structure — chips swinging the index while most stocks traded their own weather. If foreign money returns to semiconductors, the index has a direction; if the index rises while they keep selling, the bounce is thin.
3. What remains — the week's map
Monday's open is only the first checkpoint. The week holds Honam primary voting (Aug 11-14), a possible housing-supply announcement, and the power grid's peak stretch domestically; US inflation data and the road to Jackson Hole (Aug 27-29) abroad. The material's roots are in "America lost jobs in July" and "Bad jobs, good rally"; how rate cuts eventually reach household finances is today's companion piece, "How a Fed cut reaches Korean wallets."
