NH Investment & Securities Hosts NYSE Chief for Capital Market Talks in Seoul

NH Investment & Securities (KRX: 005940) hosted Lynn Martin, the head of New York Stock Exchange Group, at its Parc.1 headquarters in Seoul’s Yeouido financial district on August 11, and the two sides came away with a shared view that cooperation between the Korean and U.S. capital markets should deepen. The meeting, arranged during Martin’s visit to Korea, centered on concrete ways to expand that collaboration, according to the brokerage.

The visit brings one of the world’s oldest and largest trading venues directly to the doorstep of Korea’s brokerage industry. The NYSE traces its founding to May 17, 1792, and today operates under the ownership of Intercontinental Exchange, whose chairman is Jeffrey Sprecher. The scale gap with any single Korean institution is stark: companies listed on the NYSE carried a combined market capitalization of roughly $22.9 trillion as of the end of 2018, spread across a roster that numbered about 2,400 listed firms as of 2016.

For a Korean securities house, a direct line to that market matters on several fronts. Korean retail investors have become heavy buyers of U.S.-listed shares, brokerages compete on the quality and cost of their overseas trading infrastructure, and Korean issuers weighing a U.S. listing need banking relationships that reach the exchange itself. A face-to-face session between NH’s leadership and the NYSE’s top executive touches all three.

Traffic Now Flows in Both Directions

The Seoul meeting fits a broader pattern of institutional bridge-building between the two markets, and the movement has not been one-way. The Korea Exchange — formed on January 27, 2005 through the merger of the Korea Stock Exchange, the Korea Futures Exchange, and the KOSDAQ market bodies, and led since February 2024 by former Financial Supervisory Service chief Jung Eun-bo — has been extending its own footprint abroad. It opened a London office in May 2025 and followed with a New York office in September 2025, the latter dedicated to serving North American institutional investors.

That sequencing is telling. As Korean exchange infrastructure plants itself in Manhattan to court U.S. institutions, the NYSE’s leadership is making the reverse trip to Seoul. Both moves respond to the same underlying reality: cross-border equity flows between the two countries have grown large enough that the institutions on each side want direct relationships rather than intermediated ones.

The Open Question Is What Follows the Handshake

The announced outcome of the August 11 session was a consensus on cooperation rather than a signed agreement, and it would be premature to read specific products or listings into it. Still, the plausible avenues are well understood in the industry: smoother access for Korean investors to NYSE-listed securities, support for Korean companies considering U.S. listings, and joint work on market data or index-linked products. Which of these materializes — and on what timeline — will depend on follow-up that neither side has yet detailed.

What the meeting does establish is positioning. NH Investment & Securities has put itself forward as a Korean counterpart for the NYSE at a moment when the two countries’ capital markets are more intertwined than ever, and when Korea’s own market operators are competing to be the connective tissue. For now, that positioning — not any single transaction — is the substance of the story.
