Brokerages cut domestic branches and step up global push

Domestic Branch Shrinkage vs. Overseas Subsidiary Expansion

The numbers tell a straightforward migration pattern. Mirae Asset Securities leads with 29 overseas outlets—26 subsidiaries, three representative offices—pushing pre-tax profit at those units to 498.1 billion won. It recently launched MAPS, a global investment platform, in Hong Kong, and signed a foreign omnibus account agreement with Singapore-based UOB Kay Hian to let Southeast Asian investors access Korean equities. Samsung Securities paired a similar omnibus setup with Interactive Brokers (IBKR) and added a strategic MOU with DBS covering global wealth management, digital and AI cooperation, and two-way client referrals. Kiwoom Securities routed its omnibus pipeline through Webull. Hana Securities expanded via Emperor Securities in Hong Kong and Capital Partners in Japan.

Korea Investment & Securities ran nine overseas subsidiaries and two offices as of March 2026, splitting focus between U.S. IB and alternatives, Hong Kong Asian deal sourcing, and Vietnam-Indonesia retail. NH Investment & Securities and KB Securities are scaling overseas bond and institutional sales networks from New York and Hong Kong hubs.

For a trader evaluating a Korean brokerage, the practical question is whether your order now passes through an overseas subsidiary's routing layer. Foreign omnibus accounts aggregate investor positions into a single omnibus structure at the local brokerage, which then submits consolidated orders to the Korean market. That adds an intermediary in the execution chain—worth checking when you verify liquidity provider fees or any cost schedule that references cross-border settlement.

SIG Insider-Trading Suit Flags China Brokerage Crackdown Risk

While Korean firms push outward, Chinese-facing brokerages are under regulatory pressure in the opposite direction. Susquehanna International Group filed suit in Manhattan federal court against unidentified traders who allegedly used leaked Chinese regulatory information to net over $100 million. Between May 7 and May 21, the defendants reportedly spent $12 million on short-term put options against Futu Holdings and UP Fintech Holding. Both brokerages have already faced a crackdown sequence: proposed $338 million in penalties, app removal from mainland Chinese stores, and sharp share drops following state-media coverage.

For traders using cross-border platforms like Futu or Tiger Brokers to access Hong Kong or U.S. markets from Asia, the regulatory overhang is a concrete counterparty risk. Apps pulled from mainland storefronts, penalty proposals at the hundreds-of-millions level, and now a U.S. lawsuit tied to leaked enforcement details—each node in that chain affects platform stability, account funding flows, and withdrawal timelines.

What to Monitor

If your current broker is expanding via foreign omnibus accounts, verify the execution venue and settlement counterparty on your next trade confirmation. Omnibus structures concentrate multiple client positions under one entity, which shifts clearing risk. On the China-facing brokerage side, watch for further enforcement actions against Futu and UP Fintech; any account restrictions or settlement delays will surface first in withdrawal processing times, not in press releases.
