This week Washington named two Korean chipmakers, and Seoul named its own currency. The US Commerce Secretary said Samsung and SK Hynix had effectively been put on notice over chip tariffs; the Bank of Korea’s governor, five days earlier, had said the won “has gained a degree of immunity.” And at Friday’s 3:30 p.m. close in Seoul, the dollar bought 1,350.4 won — 22.1 won less than a week before, a 1.61% move in the won’s favor. Media reported an intraday dip into the 1,340s as the first in fourteen months; that is an intraday level, and we could not verify the closing-basis record, so no superlative here. In the week its flagship chipmakers were named as tariff targets, Korea’s currency strengthened. This piece records what was actually said on both sides. Who is right is not our call — what was said is.
For EWY holders, in two lines. (1) EWY trades in dollars but holds won-denominated assets, so this week’s 1.61% won gain offset much of the KOSPI’s −1.50% (6,788.88 → 6,687.21, KRX closes) in dollar terms. (2) The two figures are in different currencies — read them side by side, don’t net them into one number.
1. What was said this week
Confirmation strength is written in prose: on the record means named and quoted; secondhand means anonymous or indirect; unverified means not confirmed from a primary source.
| Date (KST) | Who | What was said | Strength |
|---|---|---|---|
| Aug 28 (reported Aug 30) |
Shin Hyun-song, Bank of Korea Governor — to reporters at Jackson Hole | The won “has gained a degree of immunity” · “the US raising rates does not mean we must raise — we do not mechanically track the rate gap” · up to $20bn/yr of US investment is “manageable,” citing returns on $427bn of reserves (July) · the K-dot-plot (the BOK’s new Fed-style rate-projection chart) is “not so negative — review it after a year” | on the record |
| Sep 2 (US time) | Howard Lutnick, US Commerce Secretary — CNBC, Bloomberg TV | Chip tariffs will be “targeted and thoughtful” · “if you make it in America, you pay no tariff — otherwise, brace for the consequences” · asked whether SK Hynix and Samsung had effectively been warned, he affirmed · cited TSMC’s $265bn and Micron’s $250bn as success cases | on the record |
| Sep 3 | A presidential-office official — to reporters | Tariff specifics are “not yet finalized, as far as we know… we are in close consultation so our companies are not disadvantaged” | secondhand (anonymous) |
| Sep 3 (US time) | Kim Jung-kwan, Minister of Trade, Industry and Energy — Washington | In last October’s talks the US spoke of treatment “no less favorable than competitors” for Korean chips · the US investment package is “to be finalized within September” | on the record |
| Sep 2 | Statistics Korea | August CPI +3.1% y/y — back above 3% after two months · core +3.4% | primary |
| Sep 3 | Korea Exchange | Value-up disclosures (the government push for listed firms to publish value-enhancement plans) reached 756 companies — 83.4% of listed market cap (₩5,074.4tn ≈ $3.76tn) | primary |
| Sep 2–3 (US time) | The Fed — Beige Book · Williams · Waller | The Beige Book (the Fed’s regional business survey) flagged tariff-driven input costs · Williams wait-and-see · Waller backed a September hold — FedWatch September hike odds 67.2% (Sep 1) → 62.3% (Sep 2), lower after Waller (Friday’s figure not obtained) | on the record |
Where we found no remarks: Korea’s FSC and FSS on markets, the US Treasury in writing, Japan’s MOF and BOJ. That is not a finding of silence — it is the boundary of what we checked this week.
2. The US anchor — Monday, your market closes and Seoul opens
Monday, September 7, is Labor Day. The NYSE and Nasdaq are closed while the KRX trades normally: EWY (NYSE Arca) and the SK Hynix ADR (SKHY, Nasdaq) — the practical US routes into this market — sit frozen at Friday’s New York close while Seoul moves for a full day on top of them. Tuesday’s New York open gap gets built on Monday in Seoul — and what Seoul heard this week is in the table above.
One name worth anchoring: Governor Shin spent twelve years as chief economist of the BIS — the Bank for International Settlements — and taught at Princeton before that; in US terms, an academic-international-institution central banker. Lutnick ran Cantor Fitzgerald. Not a perfect parallel: the BOK governor is not the Fed chair’s counterpart — he runs the side that watches the Fed, and what he said this week was precisely that he will watch it without mechanically following it.
3. Where the statements collide
“Immunity” vs “brace for consequences.” Shin’s remark came five days before Lutnick’s — it is not a rebuttal but a preview. His evidence: the won firming in late August even as the dollar index rose, with two short-term drivers named — inflows from SK Hynix’s US ADR listing, and exporters selling dollars. Note the loop: the very company Washington named is, by the governor’s own account, a short-term reason the won is stronger.
“Warned” vs “not finalized.” Lutnick affirmed the warning; Seoul’s first response was anonymous and modest — specifics “not yet finalized as far as we know.” Both can be true at once: the warning exists, and the rate, effective date and product scope do not. No authority stated a tariff rate this week.
“No less favorable than competitors.” The weight of Minister Kim’s sentence sits inside Lutnick’s own interview: he said Taiwan would announce another $20–30 billion “next week,” and cited TSMC and Micron as successes. The competitor Korea means is Taiwan — and Taiwan already bought its tariff down (20% to 15% in January, against $250 billion of investment). Kim’s “finalized within September” reads inside that structure; it is a minister’s schedule remark, not a signed deal.
The Fed backdrop. Last installment we wrote that Chair Warsh’s Jackson Hole speech had pushed September hike odds up. This week they came down — 67.2% to 62.3%, then lower after Waller backed a hold. Shin’s “not mechanically” line means the BOK watches its own indicators: August and September inflation, and second-quarter nominal GDP. The first of those arrived this week — CPI at 3.1%. (One media analysis put it near 2.5% excluding a base effect from last year’s telecom-fee cuts; that is media analysis, not an official figure.)
4. The market read — words and numbers, kept apart
Week: −22.1 won (−1.61%). Media attributed Friday’s move to dollar weakness after Waller, exporter selling, foreign equity buying and a firmer yen — press attribution, not an official account. Whether Korean authorities intervened was not addressed in any remark we checked, and we do not claim they did.
Stocks: KOSPI 6,788.88 to 6,687.21 on the week, −1.50%, with Tuesday’s large-cap/small-cap split and Friday’s semiconductor-led +1.64% rebound. The weekly scoreboard runs tomorrow.
Set the two numbers side by side without netting them: the won’s +1.61% is a currency return, the KOSPI’s −1.50% an index return. The intuition “EWY roughly flat in dollars” may be right — but that is a number to check against EWY’s own US closes, not to derive by subtraction.
Here is the structural fact this installment records: in the very week tariffs were aimed at Korea’s flagship chips, the won strengthened — partly, per the governor, because of chip-export dollars and a chipmaker’s US listing. The same companies are the reason the won is strong and the target of the tariff. Read together with the fact that Samsung and SK Hynix are about 41% of EWY, the ETF holds its tariff exposure and its currency exposure in the same two stocks. The memory battleground itself is in last week’s Micron piece.
5. Next week — where the words will come from
September 7 (Monday): US Labor Day — NYSE and Nasdaq closed, Seoul open. Early September: the BOK’s provisional second-quarter national accounts — the nominal-GDP number the governor flagged. September 15–16: the FOMC, entered with hike odds lower than a week ago. September 24–26: Chuseok, Korea’s autumn harvest holiday — the KRX closes. The chip tariff’s rate and date: unannounced — when they come, that week’s installment will cover them. Korea’s US investment package: “within September,” per the minister.
Under the Gat — A tariff is, so far, a sentence with no rate and no date. An exchange rate is a number stamped every day at 3:30. This week the number beat the sentence. Next week the order may flip — which is why we log the words and the numbers separately. View, not advice.
The wrap
Seoul called its won immune; Washington told Korea’s chipmakers to brace; Seoul answered that nothing is finalized and that Korea should fare no worse than its competitors. Between those sentences the won strengthened 1.61% on the week, and August inflation printed 3.1% — the first of the numbers the governor said he is watching. On Monday, America rests while Seoul trades another day on these words.
FAQ
What is the US tariff rate on Korean chips?
As of this week, none has been announced, and no effective date either. The Commerce Secretary described a “targeted and thoughtful” policy tied to US production; a presidential-office official said specifics are “not yet finalized” (secondhand).
What did the BOK governor mean by “immunity”?
At Jackson Hole (August 28, on the record) Governor Shin pointed to the won firming even as the dollar index rose, citing SK Hynix’s US listing inflows and exporter dollar selling as short-term drivers.
How did the won end the week?
1,350.4 per dollar at Friday’s 3:30 p.m. Seoul close, down 8.9 on the day; −22.1 won (−1.61%) on the week from 1,372.5. The 1,340s print was intraday.
Will the BOK follow if the Fed hikes in September?
The governor said Korea does not “mechanically track the rate gap,” while adding that persistent US hikes would change conditions and force a fresh look. He flagged August–September inflation and second-quarter nominal GDP; August CPI came in at 3.1%.
