Holding companies have become the quiet machinery of chaebol succession

Korea's largest family business groups increasingly pass control through holding-company structures, a shift that makes ownership more transparent while concentrating the succession question into a single share register.

For most of the postwar period, control of a Korean business group did not reside in any single company. It circulated. Affiliate A held shares in Affiliate B, which held shares in Affiliate C, which held shares back in A, and the founding family, holding a modest direct stake somewhere in the loop, commanded the whole ring. Circular shareholding was cheap control: a few percent of equity, leveraged through a chain of corporate cross-holdings, delivered decisive votes across dozens of companies. It was also opaque, and it meant that succession was less an act of transfer than an act of maintenance — keeping the ring intact while a son quietly accumulated positions at its most sensitive junctions.

Since the late 1990s, Korean policy has pushed steadily in the other direction. Reforms to the fair trade law made holding-company conversion easier and more attractive, and regulators tightened restrictions on new cross-shareholdings, debt guarantees between affiliates, and intra-group dealings that funneled captive revenue toward companies the family owned most directly. The result is that many of the largest groups — LG and SK among the clearest cases — now sit under a single listed parent that holds legally mandated minimum stakes in its subsidiaries. On paper this is a governance improvement. Ownership is legible, the chain of control is short, and outside shareholders can see who owns what.

But the same structure changes the arithmetic of succession rather than removing it. Under a holding-company group, control of the entire conglomerate reduces to control of one share register. An heir who secures a commanding stake in the parent inherits everything below it without touching the operating companies at all. That concentration is precisely why the corporate restructurings that precede a generational handover attract such scrutiny. The standard move is a demerger of an operating company into a holding entity and a business entity, followed by a share swap or tender offer that lets the family convert holdings in the operating unit into a larger position in the parent. Whether such a transaction is fair depends almost entirely on the ratios chosen, and ratios are where minority shareholders and controlling families have opposed interests.

Korea’s inheritance tax makes those ratios consequential. The statutory top rate sits among the highest in the developed world, and a premium historically applied to the transfer of controlling blocks, which means a straightforward bequest of a parent’s shares can force heirs to sell down or borrow heavily to settle the bill — sometimes eroding the very control they inherited. Families therefore prefer to build the successor’s stake gradually and cheaply, over years, through vehicles whose valuation is uncertain at the moment of transfer: unlisted affiliates that later merge with listed ones, convertible instruments, or companies whose value rises sharply after the heir has bought in. Most of the landmark succession controversies of the past three decades turn on some version of this pattern.

The restructurings have also become genuinely contestable. Foreign activist funds, domestic asset managers, and the National Pension Service — which holds large stakes across the market and has operated under a stewardship code since the late 2010s — now vote and litigate on merger ratios. Hyundai Motor Group shelved a major reorganization after investor opposition, and Samsung’s path to the third generation ran through a merger whose valuation became the subject of years of criminal and civil proceedings. Restructuring is no longer a purely internal family matter, which is a real constraint even when the family ultimately prevails.

What lingers is the gap between formal ownership and effective power. A holding company does not resolve the question of why a family with a minority economic interest should direct hundreds of subsidiaries and hundreds of thousands of employees; it merely states the question plainly. Investors price that ambiguity, which is part of what analysts call the Korea discount. And because the founding generation has now largely passed, the coming transfers involve heirs with thinner stakes, weaker personal authority, and sometimes siblings who dispute the arrangement — conditions under which the elegant simplicity of a single parent company can become a single point of failure.
