South Korea says API crypto trading now makes up 30% of market: Report
Von Anonym
South Korea’s FSS said API trading now makes up 30% of crypto turnover and warned it will crack down on abusive automated trading patterns, local media reported Monday.
South Korea’s Financial Supervisory Service (FSS) said Monday that API-based trading now accounts for about 30% of crypto buy-and-sell turnover, warning that some traders are using automated tools to inflate volumes and manipulate prices.
According to reports from Yonhap News Agency and Maeil Business Newspaper, the regulator warned that some traders are using automated tools to inflate volumes and manipulate prices, citing cases involving repeated small trades, spoofed orders and coordinated activity across multiple accounts.
The FSS said it will launch targeted investigations into accounts suspected of using APIs for excessive or abnormal trading patterns, signaling closer scrutiny of automated trading activity in the market.
The warning follows South Korea’s broader push to curb crypto market abuse, as regulators intensify enforcement even as parts of the legal framework remain under development.
According to the reports, the FSS described several methods used in distorting prices, including repeated placement of small market buy and sell orders to create the appearance of active trading. The regulator added that traders used higher-priced limit orders to artificially inflate prices.
In one case outlined by the FSS, a trader used API-driven orders from 5,000 won (about $3) to 10,000 won (about $6) to simulate trading activity before selling into rising prices as retail investors entered the market. In another case outlined by the FSS, a trader set a target price and repeatedly submitted higher-priced buys to drive prices to that level.

The FSS warned users against indiscriminately using high-frequency trading code shared online and urged investors to avoid chasing assets that show sudden spikes in price and trading activity without clear reasons.
The warning comes as South Korean authorities have stepped up oversight of crypto exchanges following a series of operational and fraud-related incidents.
On April 7, regulators ordered exchanges to reconcile internal ledgers with actual asset holdings every five minutes after inspections found delayed balance checks and weak trade-halting systems.
South Korean authorities also moved to tighten safeguards against scams. On April 8, the Financial Services Commission (FSC) said inconsistent withdrawal-delay exemption rules allowed bad actors to move funds quickly, with exempted accounts accounting for a majority of voice phishing losses.
At the same time, enforcement efforts have faced legal constraints. On April 9, a South Korean court overturned a partial suspension of Upbit operator Dunamu, citing unclear rules and highlighting gaps in the regulatory framework.
