The Chaebol Families: Who Controls Korea's Economy

Last updated: 2026-04-07

Five surnames run a meaningful chunk of the Korean economy. Lee, Chung, Koo, Chey, Shin. You'll see them across the Fortune Global 500, in Korean political news, in court reports, and occasionally in tabloids. They founded companies that rebuilt a war-devastated country, handed them to their children, who handed them to their children.

How a handful of families maintains control over corporations worth hundreds of billions of dollars, with ownership stakes that sometimes sit below 5%, is one of the more interesting structural facts about the Korean economy. The scandals that come with that level of concentrated power are the other interesting part.

These are estimated net worths for the lead family member of each group, based on their stakes in listed affiliates. The real picture is typically larger: family wealth is spread across spouses, children, and extended relatives, and significant portions sit in unlisted entities or foundations that don't appear in the public numbers.

Before getting to the families, it's worth understanding the mechanism. Because the Lee family owning roughly 5% of Samsung while effectively controlling a $400 billion company sounds like it shouldn't work, and yet it does.

The structure is called circular ownership (순환출자, *sunchan chulcha*). A simplified version: the Lee family owns a controlling stake in Samsung C&T. Samsung C&T owns a large stake in Samsung Life Insurance. Samsung Life Insurance owns a significant stake in Samsung Electronics. Samsung Electronics, through its subsidiaries, owns stakes in dozens of other Samsung affiliates. Loop it around, and a small entry point at the top of the chain controls the whole system.

It's not unique to Korea, but Korea refined it into an art form under Park Chung-hee's export-led growth model, when the government actively channeled capital to these conglomerates and the families were expected to deliver results in return.

The Korean government has been trying to unwind circular ownership structures for years, with limited success. The families are inventive, the corporate lawyers are expensive, and the structures have had decades to calcify.

Founder: Lee Byung-chul (1910-1987). Started Samsung in 1938 as a trading company selling dried fish and noodles. By his death it was Korea's largest conglomerate.

Current lead: Lee Jae-yong (Jay Y. Lee), third generation. Chairman since 2022 following a presidential pardon. Estimated net worth $8-10B.

Lee Jae-yong's path to the chairmanship was complicated by the fact that he spent part of it in prison. In 2017, he was arrested in connection with the Park Geun-hye corruption scandal. Samsung had paid bribes to foundations controlled by Choi Soon-sil, a presidential confidante, in exchange for government support for a Samsung merger that would have strengthened Lee family control over the group. He was convicted, sentenced, appealed, released, re-arrested, convicted again, and eventually received a presidential pardon in 2022 on the grounds that his freedom was necessary for the Korean economy.

He's now running Samsung with an estimated personal net worth of $27 billion, a number that moves significantly with Samsung Electronics' stock price. The collective Lee family stake makes them comfortably Korea's wealthiest family.

Founder: Chung Ju-yung (1915-2001). Born in what is now North Korea. Built Hyundai from a construction repair shop into one of the world's largest industrial empires with no formal engineering training.

Current lead: Euisun Chung, third generation (grandson of the founder). Chairman of Hyundai Motor Group since 2020.

When Chung Ju-yung died in 2001, Hyundai didn't pass to a single heir. It fragmented. His sons each took pieces: Hyundai Motor Group went to Chung Mong-koo, HD Hyundai (shipbuilding) to a different branch, Hyundai Development Company to another. What had been one empire became several competing ones, each still bearing the Hyundai name. The brand survived intact. The unity did not.

Chung Mong-koo, who ran Hyundai Motor Group for two decades, was convicted of embezzlement in 2007, received a suspended sentence, and eventually a presidential pardon. His son Euisun Chung took over as chairman in 2020 with a net worth of around $8.3 billion. The founding generation started with a rice shop. Three generations later, the family controls one of the world's largest automotive groups.

Founder: Chey Jong-gun. Founded the company in 1953 as a textile manufacturer, expanding it across energy and chemicals over four decades.

Current lead: Chey Tae-won, second generation (son of the founder). Chairman since 1998. Served a prison sentence for embezzlement and returned to lead SK's largest-ever expansion.

Chey Tae-won married Park Se-won in 1988, making him the brother-in-law of Park Geun-hye, who later became president of Korea. Korean politics and chaebol are entangled enough that this kind of thing barely registers as remarkable.

In 2013, he was convicted of embezzling approximately 44 billion KRW from SK affiliates and sentenced to four years. He divorced while serving his sentence. Back as chairman by 2015, he oversaw SK's acquisition of SK Hynix and the group's expansion into EV batteries and hydrogen energy. His estimated net worth sits around $3.6 billion. SK is larger and more valuable now than when he went to prison.

His son Chey In-keun is being positioned for succession.

Founder: Koo In-hwoi (1907-1969). Co-founded the company with Huh Man-jeong in 1947, starting in chemicals and cosmetics before moving into electronics.

Current lead: Koo Kwang-mo, third generation (legally adopted heir). Chairman since 2018. Net worth $2.3B. Has tripled LG's market cap since taking over.

The two founding families, the Koos and the Heos, ran LG together until a 2005 split gave the Koo family the electronics business and the Huh family what became GS Group. Amicable by chaebol standards, which is a low bar but still notable.

Koo Bon-moo ran LG until he died in 2018. He legally adopted his nephew, Koo Kwang-mo, who took over at 39 and has since tripled the group's market cap.

LG has a relatively clean record by chaebol standards. No senior family convictions, a reputation among Koreans for being the slightly more boring, stable group, which in this context is a compliment.

Founder: Shin Kyuk-ho (1921-2020). Born in Korea, built his fortune first in Japan. At the peak of Japan's asset bubble in the late 1980s, he was ranked the 4th wealthiest person in the world.

Current lead: Shin Dong-bin, second generation (younger son of the founder). Controls the Korean side of the empire following a very public family war with his brother. Estimated net worth $1.1B.

At the peak of Japan's asset bubble in the late 1980s, Shin Kyuk-ho was ranked the 4th wealthiest person in the world. When the bubble collapsed, the ranking went with it. What remained was still a substantial empire operating across Japan and Korea.

Shin Kyuk-ho had two sons: Shin Dong-joo, based in Japan, and Shin Dong-bin, based in Korea. When their father's health declined, the question of who would control the empire became the subject of a very public, very ugly family war.

Shin Dong-joo flew to Korea in 2015, appeared at a board meeting, tried to fire his brother, and failed. His father initially sided with him, then switched sides. Both brothers were eventually arrested and convicted on embezzlement charges. Their father, then in his mid-90s, was also convicted. The founder of Lotte was convicted alongside his sons for crimes at the company he built.

Shin Dong-bin emerged with control of the Korean side. The Japanese side remains a separate, ongoing dispute.

Younger Koreans have a phrase for being born into this kind of family: 금수저 (geumsujeo, gold spoon). The opposite is 흙수저 (heuksujeo, dirt spoon). The framing acknowledges something that the official narrative of meritocracy doesn't: that the starting point matters enormously, and that in a country where a handful of families control the commanding heights of the economy, some people begin so far ahead that the race is not really a race.

This has become one of the dominant anxieties of Korean society. Young Koreans who graduate from good universities, study for years, and still can't afford housing in Seoul are not especially interested in hearing about how Samsung was founded from nothing in 1938. The founding generation is gone. What remains is inherited power, and the social contract around that inheritance is under strain.

The chaebol families are aware of this. Whether the next generation of heirs governs these companies in a way that earns back some of that trust is the open question in Korean corporate life.

Contrary to what a lot of the criticism implies, I don't actually find the inheritance part that hard to understand. If I'd built something from nothing, I'd want to leave it to my kids too. Every parents wants the best for their children and leave something behind. That's not a chaebol thing, that's just people. The Lee family wanting Samsung to stay in the Lee family is not morally different from anyone else trying to set their children up well. The part that gets complicated is the scale of influence on national economic policy. The resentment on that is not unreasonable.
