South Korean Banks and IT Giants Compete for Crypto Exchange Stakes Amid Market Slump

The volume charts for South Korean crypto exchanges have cratered, falling to one-tenth of local stock market turnover. But the boardrooms of the country’s oldest banks and conglomerates don’t appear to care. Instead, they’re writing nine‑figure checks for equity in the very exchanges that traders have been abandoning.

Hana Bank, Samsung Securities, Samsung SDS, Samsung Card, Hanwha Investment & Securities, Mirae Asset Consulting, Korea Investment Securities, and even overseas player OKX Ventures are all piling into ownership stakes in Upbit, Korbit, and Coinone, according to a weekly roundup from WuBlockchain. The scramble comes as Seoul pushes forward with the institutionalization of a Korean won stablecoin, creating a regulatory runway that is tilting incumbents toward digital asset infrastructure even while retail enthusiasm cools.

Who’s Buying What

Hana Bank intends to purchase a 6.55% stake in Dunamu, the operator of Upbit, for roughly $665 million. Samsung affiliates — Samsung Securities, Samsung SDS, and Samsung Card — are jointly lining up a 4% slice of the same company. Hanwha Investment & Securities plans to add another 3.90%. If all deals close as indicated, Dunamu will suddenly count among its shareholders a cross-section of Korea’s financial and industrial backbone.

Elsewhere, Mirae Asset Consulting has decided to acquire a 92.06% controlling interest in Korbit for about $88.5 million. That move effectively takes the exchange private under a major asset manager. Meanwhile, Korea Investment Securities and OKX Ventures each plan to take roughly 20% of Coinone, splitting a sizable minority position between a domestic brokerage and a foreign exchange operator.

The sums are large by any regional standard, yet they come at a moment when South Korea’s combined crypto exchange volume has collapsed to 8% of KOSPI turnover for the month of May. In December 2024, that ratio briefly hit 323%. The divergence between market price action and institutional positioning is striking — and deliberate.

The Institutionalization Engine

South Korea’s Financial Services Commission has been advancing a framework for a won‑backed stablecoin, which would be issued by banks and used within regulated payment and settlement systems. By securing exchange equity, traditional firms are not merely buying into a retail trading venue; they are planting themselves at the center of a future on‑chain settlement layer for fiat currency. That calculus changes the risk profile of the investment. A bank owning a piece of an exchange that clears stablecoin transactions is no longer speculating on altcoin cycles — it’s acquiring essential financial infrastructure.

That infrastructure angle mirrors patterns seen outside Korea. In the same month, a global tokenization roundup captured a $4.2 billion deal and the first live tokenized Treasury settlement on-chain, reinforcing the trend of established capital anchoring itself to regulated digital asset rails.

Compliance also appears to be a motivator. Korea’s five won‑licensed exchanges — Upbit, Bithumb, Coinone, Korbit, and Gopax — operate under a strict regime that demands banking partnerships and real‑name accounts. Owning a piece of those exchanges gives banks and securities firms a direct line to the compliance process, the fee flows, and the data. It’s a defensive move as much as an offensive one.

What the Market Still Hasn’t Priced

Despite the rush, the transactions are not risk‑free. Dunamu’s valuation implies a total enterprise value north of $10 billion at a time when Upbit’s trading income is under severe pressure. If volume stays depressed for multiple quarters, the returns on these stakes could look very different. And while the stablecoin framework is advancing, no final legislation exists. A delayed or altered bill could leave institutions holding equity in businesses that were valued on a premise that hasn’t yet materialized.

OKX Ventures’ move into Coinone adds a different layer. Foreign control over any part of a won‑licensed exchange raises geopolitical and regulatory questions, particularly given ongoing scrutiny of overseas exchange operations in Asia. Even if the investment passes muster now, a change in administration or a single enforcement action could force a restructuring.

Not every jurisdiction welcomes traditional finance into crypto so fluidly. In the US, banks are actively trying to block a landmark crypto bill days before a Senate vote, illustrating how political and regulatory currents can diverge sharply from the Korean path.

For market participants, the Korean exchange stakes signal that institutions are betting on a structural, not cyclical, shift. The stablecoin project, the compliance architecture, and the record of retail adoption in previous booms suggest that even a quarter of muted volumes doesn’t deter long‑term capital. But those bets have yet to be tested by a prolonged bear market or a policy reversal. The deals are big. The premise is bigger. And the timing is anything but conventional.
