Ninety Minutes Before the Walkout, Samsung Locked in a Decade-Long Bonus Pact
The single most consequential event of the week, both for Korea and for the global memory chip supply chain, came late on Wednesday, May 20. With an 18-day strike by Samsung Electronics’ semiconductor union (May 21 to June 7) set to begin in about ninety minutes, the company and the union representing its chip workers signed a tentative agreement at the Gyeonggi labor ministry office. Korea’s labor minister mediated the final round.
The deal preserves the existing Overall Performance Incentive (OPI) and adds a separate Special Management Performance Bonus for the Device Solutions (DS) chip division. The bonus pool is set at 10.5 percent of jointly agreed business performance, with no cap on payouts, and the entire after-tax amount is paid in company stock — one-third immediately tradable, one-third locked for a year, one-third for two years. Base pay rises 6.2 percent. The new scheme runs ten years through 2035, but with hard profit triggers attached: DS operating income must reach 200 trillion won annually in 2026 to 2028, then 100 trillion in 2029 to 2035, for the bonus to be paid. A union ratification vote opened May 22 and runs through 10 a.m. on May 27.
Reading Between the Lines
The headline is "strike averted." The substance is more interesting. The union finally got what it has demanded for years — compensation tied to a hard performance number. But it accepted, in exchange, a profit threshold set by management and a stock lockup that delays liquidity by up to two years. This is not a wage deal. It is a ten-year mechanism that binds workers’ upside to the very AI memory supercycle Samsung is now riding. If the boom holds, the union will look prescient. If it cracks, the formula will be the next confrontation.
Context for international readers
Samsung Electronics is the world’s largest memory chip maker and Korea’s most valuable company, accounting for roughly 20 percent of the KOSPI index. The Device Solutions (DS) division — which makes DRAM, NAND, and HBM high-bandwidth memory for AI chips — is the single largest profit center in Korean industry. A prolonged strike would have rippled directly into AI infrastructure timelines worldwide.
Trump Pulled Back from an Iran Strike With an Hour to Go
On May 19 in Washington, President Trump told reporters at the White House construction site that he had cancelled a planned military strike on Iran with about one hour to go. He said leaders of Qatar, Saudi Arabia, and the UAE had called the night before requesting a brief extension because a negotiated settlement was close. Trump set a new deadline of "two or three days, or early next week."
By Thursday May 21 Trump was sharing a hawkish New York Post column proposing a sanctions-blockade-strikes triad. On Friday he described the talks as being in their final stage while warning of harsh consequences if Iran refused. Tehran, through Pakistan as mediator, reportedly submitted a revised 14-point counter-proposal the same day. The pattern of the week: maximum military pressure paired with active diplomacy, with the actual outcome still unresolved.
Reading Between the Lines
The "ninety minutes" framing reappears here, eerily mirroring the Samsung story on the other side of the world. Decisions made at the very edge of a deadline reveal who holds the leverage. Gulf monarchs intervening at the eleventh hour means the United States is no longer the sole architect of Middle East timing — the oil-rich brokers now influence its pauses. For Korea, importing roughly seven in ten barrels of its crude through Hormuz, every additional Iran pause is a direct subsidy to industrial planning.

Andong Summit: Lee and Takaichi Pursue an Oil and LNG Swap
Japanese Prime Minister Sanae Takaichi arrived in Andong on May 19 for a 24-hour visit, the first time a Japanese leader has travelled to the South Korean president’s hometown in answer to Lee Jae-myung’s January visit to Takaichi’s home prefecture of Nara. The joint press statement said the two governments would begin cooperation toward mutual supply and swap arrangements for crude oil, petroleum products, and LNG, with implementing details to be worked out by industry ministries.
President Lee noted that the two leaders had met four times in seven months, calling shuttle diplomacy fully established. Critical minerals, the Strait of Hormuz, and North Korea’s missile and abduction issues were also on the agenda. The next day, when Trump’s Iran pause hit headlines worldwide, the energy channels just opened in Andong moved instantly from the agenda paper to a live operational test.
Two Record Days in One Week — Korea’s Equity Market Found a New Amplitude
On Friday May 22, the KOSPI closed at 7,815.59, up 606.64 points or 8.42 percent — the largest single-day point gain ever recorded for the Korean benchmark, surpassing the 490.36-point gain set on March 5. The cross-market buy sidecar, which suspends program buy orders during sharp upward moves, was triggered for the first time since April 8. Samsung Electronics jumped 8.51 percent to a record close of 299,500 won, with Samsung group affiliates rallying in tandem.
The mirror image came exactly one week earlier. On May 15, the KOSPI breached 8,000 for the first time intraday, then closed down 488.23 points or 6.12 percent — its second-largest one-day point loss in history. A sell sidecar was triggered. Foreign net selling between mid-April and May 15 reached roughly 26.3 trillion won, but turned to net buying on May 21 and 22 as Samsung’s strike risk evaporated. Nomura published a note suggesting the index could reach 11,000 this year.
Reading Between the Lines
The KOSPI has long been the world’s purest AI hardware proxy, dominated by Samsung and SK Hynix. What changed this week is the amplitude. A market that books its largest gain and its second-largest loss in the same five sessions has graduated from "volatile" to "structurally reactive" — each new headline now moves a larger share of the index than it did a quarter ago. The Bank of Korea rate decision on May 28 and the June 3 local elections will test how long this regime holds.
Briefs

●[Korea]Special prosecutor secures first arrests in the Yoon residence probe. Arrest warrants for former chief of staff Kim Dae-ki and former protocol secretary Yoon Jae-soon were granted by the Seoul Central District Court on May 22; a third warrant for former management secretary Kim O-jin was denied. The team is investigating roughly 28 billion won in suspected misappropriation of Interior Ministry funds for the 2022 presidential residence renovation. Day 86 of the second special counsel.
●[Intl]Xi Jinping received Vladimir Putin in Beijing on May 20 — Putin’s 25th visit to China — four days after Trump’s own Beijing summit. The talks marked 30 years of the China-Russia strategic partnership and 25 years of the friendship treaty, with Ukraine, Iran, and gas pipelines on the agenda.
●[Korea]UAE’s Barakah nuclear plant — a Korean-built and partially operated facility — reported a drone strike on an external generator on May 17. No personnel were harmed, but it became the first incident at a flagship Korean nuclear export site, just as Seoul markets new reactor projects abroad.
●[Intl]The WHO declared a Public Health Emergency of International Concern for the Ebola outbreak in the Democratic Republic of the Congo, the highest-level alert in the agency’s framework.
●[Korea]Starbucks Korea’s "Tank Day" promotion, posted on the 46th anniversary of the May 18 Gwangju Uprising, escalated through the week into a government boycott call and a presidential request for legislation abolishing the statute of limitations on state violence.

SK Hynix Just Edged Past Samsung on Valuation Multiple
Less noticed amid the headline KOSPI moves: on May 18, SK Hynix’s price-to-earnings ratio reached 6.79, surpassing Samsung Electronics at 6.77. It is a small gap, but a symbolic one. For roughly two decades the market has paid more for a won of Samsung Electronics earnings than for a won of SK Hynix earnings. The order reversed quietly this week, while attention was on the strike clock.
Key takeaway
SK Hynix is the world’s dominant supplier of HBM memory for Nvidia AI accelerators — the single most concentrated bottleneck in the AI buildout. When the market values that earning power more highly than Samsung’s diversified electronics conglomerate, it is signaling that the AI memory story is now the lead story in Korean equities. Samsung’s strike resolution this week recaptured some of that narrative, but the structural rerating is real.
Context for international readers
Samsung Electronics and SK Hynix are the two largest memory chip makers in the world, supplying the high-bandwidth memory (HBM) that sits on top of every Nvidia AI accelerator. Together they account for roughly a third of KOSPI market capitalization. Their share-price ratio is, in effect, the world’s most direct equity bet on the AI semiconductor supply chain.

The Week of Ninety-Minute Decisions
This was a week defined by what almost happened. Samsung’s largest possible strike was stopped ninety minutes before it began. Trump’s Iran strike was cancelled with an hour to go. A special prosecutor secured his first arrests at day 86 of his mandate. The KOSPI rang up the largest one-day gain in its history one week after its second-largest loss. Each story was an edge-of-deadline decision, made under pressure that compressed weeks of options into minutes of choice.
There is a tempting reading here, that deadline politics works — that pushing every confrontation to the brink produces resolution. The Samsung union got a performance-linked bonus formula it could not have extracted in calmer waters. Tehran got a few more days. The KOSPI got a 600-point afternoon. But edge-of-deadline decisions also encode their cost. Samsung workers locked themselves into ten years of profit-conditional pay. Korea’s equity market now moves in amplitudes most investors are not built for. And the Yoon-era arrests are a reminder that some clocks run for years before they ring.
Three days of rest start tomorrow. By Thursday the next deadlines reappear: a central bank decision, an election that opens in two phases, a market reopening into both. The lesson of this week is not that deadlines are good. It is that we now know exactly who pays when one passes.
