IG Securities Japan Restores Order Execution After Two-Hour Disruption

IG Securities Japan has resumed order execution processing after incorrect order fills and execution delays affected some orders over a two-hour period on Thursday, the broker said. The disruption occurred between approximately 3:30 a.m. and 5:30 a.m. Japan Standard Time.

The broker is identifying affected clients and reviewing their trades, and plans to contact individual clients if further action is required. IG Securities Japan has not disclosed how many orders or clients were affected, or the extent of the impact.

The incident follows login problems reported by IG clients across multiple platforms in August 2026. IG attributed those problems to a technical issue that primarily affected client logins and later confirmed that access had been restored.

Other brokers have also reported technical disruptions affecting client access to trading services and positions. Interactive Brokers experienced login problems linked to a technical issue at certain Asia-Pacific data centres and said access was restored within an hour. At XTB, a platform failure prevented some clients from modifying or closing CFD positions; the broker said the disruption affected around 0.4% of its 25 million positions and attributed it to a technical limitation in data transfers between its trading engine and its web and mobile platforms.

Separately, OANDA Japan temporarily delayed withdrawals as a precaution following a cyberattack on a third-party hosting provider used by FX traders. The provider, GMO Internet Group, said unauthorised programs had been installed in customer server environments, potentially exposing stored MetaTrader login credentials.
