「 This Week's Lens 」
Wednesday's hawkish April FOMC minutes collided with Nvidia's record quarter; Thursday brought Korea's highest monthly producer-price print since the IMF crisis era — and the largest single-day point gain in KOSPI's history.

「 Today's Market Read 」
On the day KOSPI booked its largest-ever point gain (+606.64), US 10-year yields slipped from a 16-month high, while oil and the dollar both eased. The same set of catalysts — progress on the US–Iran deal and the chip cycle — priced into each asset on its own terms.

The chair changed. The minutes leaned the other way.
TOP STORY
Hawkish FOMC Minutes Open Door to a Hike — Five Days Into Warsh's Tenure
Minutes released Wednesday from the April 28–29 FOMC meeting showed a majority of officials prepared to entertain "some policy firming" if inflation continues to run persistently above the 2% target. The meeting itself drew four dissents — the most since October 1992. Governor Stephen Miran (the lone dove) wanted a cut, while Cleveland's Beth Hammack, Minneapolis' Neel Kashkari and Dallas' Lorie Logan supported the hold but objected to retaining the easing bias. The Wall Street Journal reported April US CPI at 3.8%, gasoline-driven. CME FedWatch readings cited across multiple outlets put the odds of a 25bp December hike in roughly the 40–60% range. Crucially, the minutes landed just five days after Kevin Warsh — Trump's nominee, widely viewed as a rate-cut advocate — was sworn in as the 17th Fed Chair on May 15.
🤖 Claude AI · Beneath the Headline
Warsh was chosen on the expectation of easier policy. Yet the minutes — drafted before his arrival but landing on his desk almost the moment he took the job — codified the opposite stance. The mechanism matters: minutes are the committee's collective record, not the chair's. What got repriced this week is that the committee, not the chairman, still drives the curve.
The 1-dove-vs-3-hawk dissent pattern fills in the rest. Miran, the lone dove, has already left the FOMC. The three hawks coordinated on stripping the easing bias. To deliver a cut, Warsh must now persuade a committee that just told the market it is leaning the other way — a task that gets harder while April CPI prints 3.8% and Hormuz remains unresolved.
🇰🇷 Why It Matters for Korea
USD/KRW closed at ₩1,506.1, holding above 1,500 for a fifth straight session despite an early dip. With KOSPI now in an 11-session streak of foreign net selling (cumulative ₩44 trillion ≈ $29 billion), a higher-for-longer Fed extends FX pressure on Korea's import bill — even as exports boom.
SECONDARY STORY
KOSPI +8.42% to 7,815.59 — Largest Point Gain in Index History on ₩42.7T of Turnover
Seoul's benchmark surged 606.64 points (+8.42%) Thursday to 7,815.59 — the biggest one-day point gain in index history, eclipsing the prior record of 490.36 set on March 5. Per Bloomberg, the percentage move was the largest since April 1. Trading volume reached 616 million shares worth roughly ₩42.74 trillion (~$28.3 billion). A buy-side sidecar triggered on KOSPI shortly after the open, with KOSDAQ following three minutes later. The index, which had bottomed near 7,053 the prior session, opened up 3.85% and accelerated through the day. Three catalysts converged: Samsung Electronics' last-minute wage deal averting a planned strike, Nvidia's record quarter, and renewed optimism on a US–Iran de-escalation. Institutions absorbed roughly ₩2 trillion of net buying; foreigners continued to sell but at a far slower pace. KOSDAQ closed up 4.73% at 1,105.97.
SECONDARY STORY
Korea's May 1–20 Exports +64.8% to $52.6B — Chips +202%, an All-Time Mid-Month Record
Korea Customs Service preliminary data released Thursday showed exports in the first twenty days of May at $52.65 billion, up 64.8% year-on-year and a record for the period — far above the prior $38.6 billion mark from May 2022. Working days totaled 13.5 (one more than a year ago); daily average exports rose 52.6% to $3.9 billion. Semiconductors led at $22.0 billion (+202.1%) — also a mid-May high — accounting for 41.7% of total exports, a 19.0 percentage-point jump versus a year ago. Computer peripherals (+305.5%) and petroleum products (+46.3%) also surged. Passenger cars fell 10.1%, a second straight monthly decline.

Nvidia Posts Record $81.6B Quarter — But US Stocks Fell Thursday Anyway
Why it's here — The single biggest momentum stock cleared every bar and didn't rally. That, in itself, is a signal.
Nvidia's Q1 FY27 results (quarter ended April 26, 2026), released after Wednesday's close, set company records: revenue of $81.6 billion (+85% YoY, +20% QoQ); Data Center revenue of $75.2 billion (+92% YoY); GAAP gross margin of 74.9%; GAAP EPS of $2.39 versus non-GAAP $1.87 (consensus $1.77). The company returned a record $20 billion to shareholders in the quarter via buybacks and dividends, and authorized an additional $80 billion repurchase on top of $38.5 billion remaining — roughly $118.5 billion in dry powder, with no expiration. The quarterly dividend was lifted from $0.01 to $0.25, a 25× increase. Yet on Thursday the S&P 500 slipped ~0.45%, the Nasdaq ~0.50% and the Dow ~0.48%; Nvidia itself closed broadly flat. Some analysts had penciled in next-quarter guidance closer to $86 billion, and the company's print — while a beat — did not clear that upper bar.
🤖 Claude AI · Beneath the Headline
A record quarter, a record buyback, and a 25× dividend hike — and the stock did not move. That is not weakness; it is saturation. The market had already priced "another beat" into Nvidia. The new bar is no longer beating consensus; it is clearing the optimists' Street-high estimate.
Even so, the ~$118.5B buyback authorization plus the 25× dividend increase put a structural floor under EPS regardless of price. The AI infrastructure cycle itself is not slowing — the share price simply ran ahead of it. For Korean HBM and DRAM suppliers, the cycle itself is what matters, not Thursday's tape.
🇰🇷 Why It Matters for Korea
Nvidia's print landed before KOSPI opened Thursday and helped lift Samsung Electronics (close ₩299,500, +8.51%) and SK Hynix (close near ₩1.94 million, up ~11%). Korean DRAM producer prices were up ~398% YoY in April per BOK data — the same compute-demand engine behind Nvidia's data-center number. Samsung Electronics alone accounts for roughly a fifth of KOSPI market capitalization.
Crude Falls ~6% in Two Sessions on Iran-Deal Optimism — US SPR Drained 10M Barrels in a Week, a Record Pace
Why it's here — The Hormuz variable moves US inflation and Korea's trade balance with a single lever.
WTI crude slid to around $99 on Thursday, completing a ~6% two-day pullback. President Trump described US–Iran negotiations as in their "final stages" and signaled patience for a few more days; satellite tracking showed three supertankers transiting Hormuz. Meanwhile the US Strategic Petroleum Reserve drew down roughly 10 million barrels last week — the largest weekly release on record — as part of the 172-million-barrel discharge announced March 11 over a 120-day window (~1.43 million barrels per day). Crude nevertheless remains nearly 50% above pre-war levels. A Reuters report that Iran's Supreme Leader directed near-weapons-grade uranium to remain inside the country complicated the deal picture later in the session.
🤖 Claude AI · Beneath the Headline
The "record weekly SPR draw" is the heaviest detail here. Trump has roughly four weeks until the June 16–17 FOMC, and the fastest tool he has to soften inflation in that window is the reserve, not diplomacy. Oil is not only falling because the deal is closer — it is falling because Washington is pushing it down.
The risk lies on the other side. The SPR takes years to refill, and refill demand itself becomes a future price floor. If talks fail, the US faces a depleted reserve into a re-closed Hormuz — a tail the market is not yet pricing at majority odds.
US 10-Year Yield Slips to 4.57% from 16-Month High of 4.70%
Why it's here — The corridor between hawkish minutes and easing hopes just got narrower.
The benchmark US 10-year Treasury yield, which touched a 16-month high of 4.70% on May 19, pulled back to 4.569% by Thursday's close — down about 10 basis points on the day — as Iran-deal optimism temporarily eased inflation fears. The 30-year yield also fell 6.6 bp to 5.114%. After the April FOMC minutes, markets repriced a 25bp December hike at roughly 40–60% probability, reviving the "higher for longer" narrative that had faded earlier this year.
➤ One-Line Read: The bond market pulled back from the highs, but the goalposts have moved — "when does the next hike come?" has replaced "when does the next cut come?" as the operative question.

Korea's April PPI +2.5% MoM — Highest Monthly Print Since February 1998
Why it's here — Released the same day KOSPI surged; the data points the other way.
The Bank of Korea reported April Producer Price Index at 128.43, up 2.5% month-on-month and 6.9% year-on-year — the largest monthly rise since February 1998, 28 years and 2 months ago, and the highest annual reading since October 2022. Korean PPI has now risen for eight straight months. Manufacturing PPI was up 11.3% YoY, led by a 73.9% surge in coal and petroleum products; computers and electronics rose 17.4%, chemicals 15.6% and basic metals 11.8%. Most striking, DRAM producer prices were up ~398% YoY, reflecting the global memory shortage. The BOK pointed to the ongoing Middle East war as the primary supply-side driver. Producer prices tend to feed into consumer inflation with a one-to-three-month lag — and April CPI had already reached 2.6% YoY, the highest since July 2024 per Reuters. Context: BOK has held its base rate at 2.50% since the May 2025 25bp cut — seven consecutive holds through the April 10, 2026 meeting. New Governor Hyun Song Shin, formerly of the BIS and Princeton, took office April 21 and faces his first Monetary Policy Board decision on May 28.
🤖 Claude AI · Beneath the Headline
Producer prices typically pass through to consumer prices with a one-to-three-month lag. April's +2.5% MoM therefore translates into renewed CPI pressure into June and July — precisely when the Bank of Korea would otherwise be considering easing. It is not a coincidence that the Fed's hawkish minutes arrived in the same week. Both central banks are caught in the same corridor, on the same side of the trade-off.
The release also exposes a contradiction inside the data. The same index is being pushed up by energy on the cost side and by memory chips on the demand side. Korea's export boom is generating its own domestic inflation pressure, with the won at ₩1,506 amplifying the import bill. The +606-point KOSPI surge sits on top of that, not separate from it.
Samsung Electronics Settles With 70,000-Member Union on Eve of Strike — Uncapped DS Bonus a First
Why it's here — A global chip-supply tail risk eliminated overnight. The second engine behind Thursday's +8.42% KOSPI move.
Samsung Electronics and the Samsung Electronics Branch of the National Samsung Group Labor Union reached a tentative wage deal at 10:40 p.m. on May 20 at the Gyeonggi Regional Labor Office, with Labor Minister Kim Young-hoon mediating. The union — Samsung's largest, with more than 70,000 members per UPI/Yonhap — suspended an 18-day full strike scheduled to begin May 21. The headline term: the existing Overall Performance Incentive (OPI) scheme is preserved, but a new special performance bonus is created for the Device Solutions (DS, semiconductor) division with no cap on payout — funded at 10.5% of business performance, with a 40%/60% allocation between division and business unit. Childbirth allowances rise (₩1m / ₩2m / ₩5m for first/second/third+); the DX division and CSS unit receive ₩6m in stock equivalents. Newspim cited industry estimates that memory-business employees on a roughly ₩100m base could see total bonuses approach ₩600m at the upper end. Union members vote on ratification from May 22 (2 p.m.) through May 27 (10 a.m.). Context: Samsung Electronics is roughly a fifth of KOSPI market capitalization; the planned strike risked HBM/memory supply during the AI buildout.
🤖 Claude AI · Beneath the Headline
The crucial clause is "uncapped DS bonus, funded at 10.5% of business performance." The union's real demand was never just pay — it was a formal mechanism to share the upside from the HBM/DRAM super-cycle. Tying compensation to a percentage of operating performance with no ceiling is the first time that bargain has been codified at Samsung. It effectively makes labor a structural participant in the chip cycle.
Thursday's +8.42% KOSPI move was not only relief that the strike was averted. The market read it as an extension of the chip cycle's runway — less attrition risk, less management bandwidth lost to labor disputes, more capex going to capacity. That said, the May 22–27 ratification vote remains the real gate; a "no" outcome cannot be ruled out.
Foreigners Net-Sold KOSPI for an 11th Straight Day — Even as the Index Surged
Why it's here — A record-day rally with foreign outflows is, in itself, a structural shift.
Foreign investors were net sellers on KOSPI Thursday for an 11th consecutive session, matching the longest stretch of 2026. Cumulative foreign outflows since May 7 now exceed ₩44 trillion (~$29 billion). On May 7 alone, foreign net selling hit ₩7.17 trillion, surpassing the previous single-day record of ₩7.08 trillion set February 27. The pace, however, eased sharply on Thursday — to roughly ₩200 billion, per local reports — as global risk appetite improved. The rebound was driven by domestic institutions (about ₩2 trillion of net buying); retail investors took profits. Context: as of mid-day Thursday, The Korea Herald reported foreign net sales of ₩437.4 billion (~$291.6 million) before the pace slowed into the close.
➤ One-Line Read: Foreigners keep leaving, and the index keeps climbing — Korean institutions and retail absorb the supply, with sidecars triggering on the way up. The buyer base of KOSPI is quietly being rewritten.
Brief
Claude AI
● Samsung Union Ratification Vote — May 22 (2 p.m.) through May 27 (10 a.m.). A "no" would put the 18-day strike back on the table.
● Bank of Korea MPB Meeting — May 28. Governor Hyun Song Shin's first policy decision; base rate at 2.50%, with PPI now at a 28-year monthly high.
● Korea May Trade Data (full month) — Korea Customs Service releases June 1. Watch for May to become the third consecutive month above $80 billion.
● US PCE Inflation (April) — Released May 29 ET. The first data test of the April minutes' hike scenario.
● June FOMC — June 16–17. Markets price a hold at ~89%; the December hike probability has risen post-minutes to roughly 40–60%.

「 Throughline 」
Two Chairmen, One Market
Two central bank governors took office in the same season. Hyun Song Shin entered the Bank of Korea on April 21; Kevin Warsh entered the Federal Reserve on May 15. By May 21, both had been overtaken by their own data. The April FOMC minutes — drafted before Warsh and released after him — opened the door to a hike. Korea's April PPI, the highest monthly print since the IMF crisis era, did the same to whatever easing path Shin might have wanted. Neither chairman can move first.
And yet, on the very morning that constraint became visible, KOSPI booked the largest single-day point gain in its history — powered by chips and a wage deal, two stories entirely outside the central bank window. So the real question is not who chairs the Fed or the BOK. It is which gives first: the Korean chip cycle, or the Hormuz negotiation. One breaks, and Thursday's +606 points becomes a mirage. Both hold, and 7,800 becomes the new floor.
