「 Today's Market Read 」
Crude, yields, and the dollar moved in one direction; stocks, gold, and silver fell together. A signal that "safe haven" is not a stable category right now. The won crossed back above 1,500 per dollar for the first time since April 7.

The KOSPI touched a dream — and foreigners left the table.
TOP STORY
KOSPI Crosses 8,000 for First Time, Then Plunges 488 Points — Second-Largest Closing Loss on Record
Korea's benchmark KOSPI index crossed 8,000 for the first time in early trade on May 15, peaking at 8,046.78, before a wave of foreign selling drove it down 488.23 points (-6.12%) to close at 7,493.18 — the second-largest one-day point loss in its history. The tech-heavy KOSDAQ fell 5.14%. A sell-side circuit breaker tripped at 1:28 p.m. local time, the first such trigger in a month. Foreigners net-sold ₩5.61 trillion ($3.74 billion) for a seventh straight session. Retail investors absorbed a record ₩7.18 trillion in a single session — the largest single-day net buying in Korean market history — but could not stem the slide. The VKOSPI fear gauge surged to 74.71, near its all-time high.
๐ค Claude AI · Beneath the Headline
On the surface this looks like profit-taking. The deeper read is that the peak itself was the inflection point. The KOSPI gained 20.9% in May through the 14th — clearing 1,000 points from 7,000 to 8,000 in just eight sessions. The rally stacked three catalysts into one window: a 149.8% YoY jump in May 1–10 semiconductor exports, AI-memory demand upgrades, and Trump–Xi summit optimism. With every catalyst already in the price, there was nothing left to buy.
Korea's total market cap briefly overtook Taiwan's to rank sixth globally during the week. But the engine was overwhelmingly Samsung Electronics and SK hynix — together they accounted for the top two foreign sell tickets on Friday (SK hynix ₩2.59 trillion, Samsung ₩2.50 trillion), nearly half the day's foreign outflow. The semiconductor story is real; so is the concentration. When two stocks carry a market, every move — up or down — carries their full weight. Nvidia earnings on Wednesday and the Suwon District Court ruling on Samsung's strike on May 20 will write the next chapter.

Trump–Xi Beijing Summit Ends Without Concrete Trade Terms
The two-day Beijing summit (May 14–15) closed with President Trump calling the trip "incredible" and announcing China's commitment to buy 200 Boeing 737s, U.S. soybeans, oil, and LNG. USTR Jamieson Greer separately suggested a roughly $10 billion agricultural commitment and a "Board of Trade" framework covering about $30 billion in tariff reductions. The two sides agreed on a three-year "strategic stability" frame; Xi will visit the U.S. on September 24. Boeing shares fell 3.8% on Friday — a measure of the market's disappointment.

Powell Steps Down, Warsh Sworn In as 17th Fed Chair — Tightest Confirmation Margin on Record
Kevin Warsh was confirmed by the Senate 54–45 on May 13 and took the chair on May 15. Bloomberg called it the "slimmest confirmation margin ever for a head of the central bank." Only Pennsylvania Democrat John Fetterman crossed party lines. Powell will remain on the Board through 2028 — the first former chair to stay on since Marriner Eccles in 1948. Warsh's first FOMC meeting is June 16–17.

Trump–Xi Summit: "Fantastic" Trade Deals, Faint Trade Terms
Why this matters
The October 2025 one-year U.S.–China trade truce expires this October. The summit was the first leaders' meeting before that deadline — and the moment Korea's two largest export markets begin to re-set their terms.
What happened
The May 14–15 Beijing summit produced more atmospherics than specifics. China committed to an initial 200-aircraft Boeing order (Boeing called it the first tranche with "further commitments expected") and to buying U.S. soybeans, crude, and LNG. USTR Greer separately disclosed an approximately $10 billion agricultural commitment and a "Board of Trade" framework covering about $30 billion in tariff reductions. The two sides agreed on a three-year "strategic stability" framework, and Trump invited Xi to visit the U.S. on September 24. The U.S. delegation included Boeing CEO Kelly Ortberg, Nvidia's Jensen Huang, Apple's Tim Cook, Tesla's Elon Musk, and twelve other executives.
๐ค Claude AI · Beneath the Headline
Despite Trump's "fantastic deals" framing, the market sold off. U.S. equities fell more than 1% on May 15, the 10-year Treasury yield climbed to 4.59%, and Boeing shares dropped 3.8%. The reason is simple: investors wanted the shape of the tariff architecture, not just a list of purchases — and both sides chose to keep that part private. CBS quoted Capital Economics: analysts are not seeing a big win for the U.S.
Xi appears to have tried to convert Trump's transactional bargaining style into a longer-term operating framework — one durable enough that a future U.S. administration would inherit it. The September 24 return visit secures one more negotiating table before the October truce deadline. The market read this as a signal that the tariff structure will not be resolved before then.
๐ฐ๐ท Why It Matters for Korea
For context, South Korea's exports are equivalent to roughly 40% of GDP — the highest ratio in the G20 — and shipments to China rose 81.8% YoY in the May 1–10 period (Korea Customs Service). If China shifts more demand toward U.S. soybeans, energy, and aircraft, Korean exporters in those overlapping segments lose relative competitiveness. And if U.S.–China relations stabilize, the "China detour" premium that Korean semiconductors enjoyed during the trade war becomes less valuable. The shape of the next deal matters more to Seoul than the headline number.
From Powell to Warsh — On the New Chair's First Day, the 10-Year Hits a One-Year High
Why this matters
Eight years of Powell ended Friday. Warsh sat in the chair the same day the U.S. 10-year yield reached its highest level in a year. The market priced the transition in real time.
What happened
Kevin Warsh was confirmed by the Senate 54–45 on May 13 and was sworn in as the 17th Federal Reserve Chair on May 15. The same day, the U.S. 10-year Treasury yield rose roughly 10 basis points to 4.59% — its highest level since February 2025. April CPI ran at 3.8% YoY; April PPI posted its largest single-month gain since early 2022. CME FedWatch now assigns near-zero odds to additional rate cuts in 2026 and prices roughly a 50% chance of a December rate hike. Powell will remain on the Board until 2028 — the first former chair to stay since Marriner Eccles in 1948. Warsh's first FOMC meeting is June 16–17.
๐ค Claude AI · Beneath the Headline
Warsh carries a "hawkish" label, but the reason Trump picked him is to deliver lower rates. In confirmation hearings Warsh said he "takes no instructions from the administration." The market did not take that at face value — Powell's decision to stay on the Board is the tell. Powell framed his stay as "until the renovation investigation closes," but in practice he is an institutional counterweight should Warsh bend toward political pressure (CNN, Bloomberg).
A 4.59% 10-year yield is not a pure inflation signal. It is the market's first price on the new chair. April CPI at 3.8%, the largest monthly PPI jump since early 2022, and the Iran war's persistent oil shock all greeted Warsh on day one. Investors began pricing the scenario in which any attempted cut would re-anchor inflation expectations upward. The cut Trump wants will arrive at the moment it is least able to work.
๐ฐ๐ท Why It Matters for Korea
The pressure landed in Seoul immediately. The won closed at 1,500.8 per dollar on May 15, the first time it crossed back above 1,500 since April 7, and FX-loss concerns helped intensify foreign selling. The Bank of Korea — which has held its base rate at 2.50% for seven consecutive meetings — meets next on May 28 under new Governor Shin Hyun-Song. With the Fed effectively off the cutting path, BOK's room for an independent move narrows; cutting alone amplifies KRW volatility.
Hormuz Closed for 73 Days — WTI +11% on the Week, Silver -10.6% in a Single Session
Why this matters
The Strait of Hormuz closure that began March 4 has now run for 73 days. As the largest energy supply shock since the 1970s settles into chronic territory, May 15 was the day investors began reconsidering what "safe haven" actually means.
What happened
WTI crude closed up 4.20% at $105.66 per barrel on May 15 and gained 11% on the week (Macrotrends, Barchart). The same day, gold fell 2.00% to $4,556, while silver collapsed 10.61% to $77.52 — Bloomberg described it as "the close of a rollercoaster week." President Trump rejected Iran's latest peace proposal language, then softened his tone alongside Xi to say "we want the strait open." The IEA warned that even if fighting ends in May, the global oil market will remain materially undersupplied through October.
➤ One-Line Read: Oil up and silver crashing on the same day — markets are rewriting the definition of "safe haven." For Korea, that means a 1,500-plus won and inflation pressure still rising in parallel.

Record May 1–10 Exports Mask a Hollowing Out — Chips Hit 46.3% of Total, Non-Chips Slip to $9.9B
Why this matters
South Korea posted its best-ever May 1–10 export figure — but strip out semiconductors and the rest of the export basket fell below $10 billion for the first time in seven months. The same imbalance that explains the KOSPI's volatility now shows up in the export ledger.
What happened
Korea Customs Service preliminary data released May 11 showed early-May exports of $18.43 billion, up 43.7% year-over-year — a record for the first ten days of any May. Semiconductors led with $8.54 billion, up 149.8% YoY; computer peripherals rose 382.8%. But non-chip exports came in at $9.9 billion, down $6.7 billion from the previous month and the first sub-$10 billion reading since October. Passenger vehicles fell 26.0%; ships fell 58.6%. By destination, shipments rose 81.8% to China, 96.7% to Taiwan, 89.3% to Vietnam, 17.9% to the U.S., and 11.3% to the EU. The 10-day trade surplus was $1.7 billion.
๐ค Claude AI · Beneath the Headline
Behind "record high" sits one word: concentration. Semiconductors now account for 46.3% of exports, up 19.7 percentage points YoY. Non-chip exports of $9.9 billion fell to a seven-month low. The autos (-26%) and ships (-58.6%) collapses are not noise; they are the visible footprint of U.S. tariff policy settling into Korea's traditional manufacturing base. A single product line is now compensating for that gap.
Recall that Korea's exports run at roughly 40% of GDP — the highest ratio in the G20 — and within that, semiconductors are pushing toward half. In effect, around 20% of Korea's entire economy now hangs on one product category. While the AI super-cycle holds, this is a tailwind. Once the memory cycle turns, or U.S. semiconductor tariffs widen, the shock falls in the same place. The 6% KOSPI drop on May 15 came from the same logic: when one pillar carries the building, the building moves whenever the pillar does.
Samsung Electronics: 18-Day Strike Set for May 21 – June 7; Government Floats "Emergency Mediation"
Why this matters
Samsung Electronics — roughly 25% of the KOSPI by market capitalization — is three days away from what would be only the second strike in its history. The Suwon District Court's injunction ruling on May 20 and the strike start on May 21 are this week's single largest market variable.
What happened
Post-mediation talks at the National Labor Relations Commission collapsed on May 12–13. The union (Cho-Gi Eopno Samsung Electronics Branch) has announced an 18-day general strike from May 21 to June 7, with 41,000 of approximately 90,000 members signaling participation, potentially rising to 50,000 (Dealsite). The core dispute is institutionalizing the Overtime Profit Incentive (OPI) at 15% of operating profit (about ₩45 trillion) and removing its cap; management offered 13–14% plus expanded stock-based OPI, but talks broke down. The Suwon District Court will rule on management's injunction against unlawful labor action on May 20, one day before the strike. Industrial Affairs Minister Kim Jung-kwan said on May 14 that "if a strike occurs, emergency mediation will be inevitable." JPMorgan estimates a strike could cut operating profit by more than ₩40 trillion; industry sources cite damage estimates up to ₩100 trillion.
๐ค Claude AI · Beneath the Headline
Read narrowly, this is a labor dispute. Read structurally, it is Korea's single-stock dependency made visible. The country's largest company by market cap (~25% of the KOSPI), the central driver of the May 1–10 semiconductor export print, and the apex of a 1,700-firm supplier ecosystem is three days from possibly halting for 18 days. The government's pivot toward "emergency mediation" so soon after the failed talks is itself a tell — a sharper register than its earlier insistence on voluntary resolution.
Two scenarios split the week. If the court grants the injunction on May 20, it restricts occupations of safety facilities — but only about 10% of union members fall under that scope, so the broader strike still proceeds (per legal-affairs commentary cited by Dealsite). If denied, the full 18-day stoppage begins on schedule. Either way, the pivot point falls on the May 21 open. Some global hyperscalers are already asking Samsung whether their memory orders are at risk, and Chinese memory makers stand to benefit from any sustained supply gap.
BOK Governor Shin's First G7 Appearance May 18–20, Then First Rate Meeting May 28
Why this matters
A first G7 invitation for the Bank of Korea's chief and a first rate-setting meeting under a new governor — both in the same week. With the Fed effectively off the cutting path, Shin's opening tone matters more than the headline decision.
What happened
The Bank of Korea has held its base rate at 2.50% for seven straight meetings (the last on April 10). May 28 will be the first rate decision under Governor Shin Hyun-Song, who took office April 21 after serving as head of research at the Bank for International Settlements (BIS). Korean April CPI accelerated to 2.6% YoY from 2.2% in March; the BOK's monthly report sees inflation rising into the "upper-middle 2% range." In his inaugural address, Shin twice emphasized that the Iran-war supply shock complicates both inflation and growth paths simultaneously, requiring policy to be "prudent and flexible." This week, Shin departs for Paris on May 18 — the first sitting BOK governor invited to the G7 finance ministers' and central bank governors' meeting — and returns May 20.
➤ One-Line Read: The first message from a new central banker tends to live in the meeting record more than the decision itself. The May 28 minutes will be priced again, separately.

The Market Touched a Dream, Then Woke Up
Four things happened on May 15. The KOSPI broke 8,000 for the first time and closed down 6.12% by the bell. Powell left and Warsh arrived. Trump and Xi finished their summit in Beijing. The U.S. 10-year yield reached a one-year high of 4.59%. Each event reads as its own story. The market answered them all with the same line — what comes next is not yet visible.
8,000 was a passage, not a destination. The summit was a wait, not an agreement. The new chair was a test, not a beginning. Prices that had climbed for nearly a year had pulled the next catalyst forward. With every catalyst released in the same week, only one question is left. Where does the next story come from?
