South Korean Brokerages Rush into Crypto Exchanges to Secure Tokenized Future

Traditional financial institutions in South Korea are rapidly shifting their capital into the digital asset market. In a wave of high-profile equity acquisitions, the country’s leading securities firms and major corporate conglomerates are buying major stakes in local cryptocurrency exchanges. The primary catalyst is not a sudden appetite for trading volatility; it is a coordinated, strategic race to build out infrastructure for the country’s highly anticipated tokenized securities and stablecoin frameworks.

The Race for Exchange Infrastructure

The momentum reached a new peak on Friday as Korea Investment & Securities (KIS) finalized a strategic investment agreement with Coinone, one of the nation’s core virtual asset platforms. Simultaneously, global exchange operator OKX Ventures joined the deal, with both entities acquiring a significant foothold.

Strategic Investor	Target Platform	Equity Stake	Transaction Rationale
Korea Investment & Securities	Coinone	~20%	Security Token Offerings (STOs) & stablecoin services
OKX Ventures	Coinone	~20%	Global operational playbook & compliance tech

According to KIS CEO Kim Sung-hwan, the partnership represents a decisive move beyond conventional banking toward blockchain-based digital financial services. By anchoring themselves to Coinone’s infrastructure, KIS plans to establish early dominance in issuing and distributing security tokens. Under current local securities laws, traditional crypto exchanges are restricted from independently intermediating tokenized assets, making joint ventures with licensed brokerages a operational necessity.

Samsung Enters the Matrix

This development arrived immediately after a massive multi-affiliate block sale by tech giant Kakao. Three core arms of the Samsung Group agreed to purchase a combined 4% stake in Dunamu, the parent company of South Korea’s dominant crypto exchange, Upbit, for 612.8 billion won (approximately $408 million).

Samsung Affiliate	Acquired Stake	Operational Mandate
Samsung Securities	2%	Tokenized asset distribution & virtual asset custody
Samsung SDS	1%	AI, cybersecurity, and institutional cloud infrastructure
Samsung Card	1%	Stablecoin payment ecosystem integration via Monimo app

Each Samsung entity is stepping into the ecosystem with a highly specialized task. While Samsung Securities focuses on the distribution mechanics of the digital asset market, Samsung SDS—the group’s enterprise IT arm—is combining its cloud and cybersecurity tech with Dunamu’s blockchain rails to build institution-grade digital financial infrastructure. Concurrently, Samsung Card is laying the groundwork for a retail payment network built around future won-based stablecoins.

Dismantling the Regulatory Wall

The sheer volume of capital moving into exchange operators highlights an aggressive consolidation trend across South Korea’s financial elite. Traditional banks and legacy firms are no longer sitting on the sidelines.

Legacy Financial Peer	Target Platform	Position Update
Hana Bank	Dunamu (Upbit)	Acquired a 6.55% stake for roughly $670 million
Hanwha Investment & Securities	Dunamu (Upbit)	Expanded total holdings to 9.84%
Mirae Asset Financial Group	Korbit	Secured a 92% controlling stake for $106 million

This institutional wave marks a major turning point for the local market. Since 2017, South Korean financial authorities have maintained a strict, de facto ban on financial firms directly holding or participating in cryptocurrency operations. However, with lawmakers actively shaping the comprehensive Digital Asset Basic Act, regulators have quietly eased their stance to bring the country’s financial plumbing in line with global digital asset trends.

The ultimate goal for these financial giants is the launch of unified investment platforms. By merging traditional equity markets with blockchain technology, brokerages are preparing for a future where retail users can manage stocks, tokenized real-world assets, and digital currencies through a single, compliant application.
