Offshore Korean Stock Perpetuals Surge, Challenging Spot Price Discovery

Offshore crypto exchanges have expanded perpetual futures linked to Korean equities, allowing investors to trade exposure beyond local stock-market hours. Unlike conventional cash equities, these contracts can change hands around the clock, potentially incorporating company news and global market moves before Korea’s exchanges reopen. Their growth matters because price signals formed offshore could increasingly influence domestic shares, weakening the local market’s traditional role in price discovery.

A Tiger Research report said Korean stock perpetuals traded on offshore crypto venues, including Hyperliquid, generated 307 trillion won in cumulative volume over the latest eight-month period. That was nearly four times the combined turnover recorded by Korea’s five domestic exchanges, according to the report. The surge is beginning to reverse the conventional relationship between the two markets, with derivatives prices increasingly exerting influence on underlying cash equities.
