The New York Stock Exchange and the Korea Exchange signed a memorandum of understanding on September 3, 2026, in New York. The partnership aims to modernize operational infrastructure and improve access to South Korean capital markets for global investors.

The collaboration focuses on transitioning to a T+1 settlement cycle, extending trading hours, and developing joint ETF products. Both exchanges plan to share market data to facilitate the creation of new index products.

To manage these initiatives, the parties will establish the NYSE-KRX Joint Collaboration Council. No specific timelines for the implementation of these changes have been announced as of now.

This agreement follows a 2004 memorandum between the two entities, though the current version is described as more focused on operational efficiency. The move aligns with recent efforts by the Korea Exchange to attract institutional capital.
