Kakao Pay Taps Nasdaq's Siebert to Bring Tokenized Korean Stocks to Wall Street
Siebert Financial Corp. (Nasdaq: SIEB) has agreed to serve as the U.S. partner for Kakao Pay Securities in a plan to bring South Korean stocks to American investors outside normal market hours. The partnership, announced Monday under the name K-Stock Global Gateway, combines Siebert’s U.S. brokerage infrastructure with Kakao Pay Securities’ reach inside South Korea, where the firm holds roughly 9 million stock accounts.
The core problem the partnership targets is time zones. South Korean and U.S. markets operate on opposite sides of the globe, making it difficult for a trader in New York to buy or sell Korean shares during the Korean trading session. To work around that gap, Siebert and Kakao Pay Securities plan to explore tokenizing South Korean equities. A tokenized share can trade on a blockchain-based system outside the hours of the underlying stock exchange, giving U.S. investors a path to Korean equities even when Seoul’s markets are closed.
The companies are also looking at whether tokenized securities can support T+0 settlement, meaning trades would settle the same day instead of the standard multiday cycle. Faster settlement would let investors access proceeds from a sale sooner.
The initial service is targeted for the first half of 2027. Kakao Pay Securities brings about 9 million existing stock accounts into the arrangement. Tokenization is described as one of several products the partnership plans to build, not the end goal. Any rollout depends on regulatory approval in both the U.S. and South Korea.
Siebert CEO John J. Gebbia said Kakao Pay Securities’ choosing Siebert as its U.S. partner validates the financial infrastructure Siebert has built. He said tokenization is an important first opportunity, but the partnership is designed to go further, connecting investors in both markets to products that were previously hard to reach. Kakao Pay Securities CEO Simon Shin said the goal is to build a global gateway for Korean shares by pairing his firm’s technology, content, and community reach with Siebert’s U.S. market access.
Siebert and Kakao Pay Securities say tokenization is one piece of a larger plan. The two firms intend to identify additional ways to connect U.S. and Korean investors over time, including new financial products and cross-border investment opportunities. The partnership also aims to combine brokerage access with market content and investor education, giving American investors more context on South Korean companies.
Nothing in the announcement is final. Siebert and Kakao Pay Securities both note that any implementation remains subject to regulatory requirements and investor protection standards in the U.S. and South Korea. For now, the deal signals that a Nasdaq-listed U.S. brokerage sees tokenized real-world assets (RWAs) as a practical tool for solving a concrete problem: time zones separating global markets.
