Execution resumes as checks begin
IG Securities Japan has restarted order execution after incorrect fills and delays affected some orders during a two-hour disruption on Thursday, 29 October 2026. The event ran from approximately 3:30 a.m.
To 5:30 a.m. Japan Standard Time. Some fills did not match the intended prices.
The broker is locating affected clients and examining their trades. It says it will contact clients individually where further action is needed. IG Securities Japan has not said how many customers or orders were involved, or given a measure of the incident's impact.
The execution problem follows login trouble for IG clients across multiple platforms in August 2026. IG linked that earlier incident to a technical fault that mainly disrupted client logins, then said access had been restored.
Other brokers report service faults
Interactive Brokers also reported login trouble, which it linked to a technical problem at some Asia-Pacific data centres. The broker said access returned within an hour. Finance Magnates reported on the other broker disruptions alongside the IG incident.
XTB said a platform failure left some clients unable to change or close CFD positions. The firm put the affected share at around 0.4% of its 25 million positions and attributed the problem to a data-transfer limitation between its trading engine and its web and mobile platforms.
OANDA Japan temporarily held back withdrawals as a precaution after an attack on an outside hosting company relied on by FX traders. GMO Internet Group said customer server environments contained unauthorised programs, creating a potential risk to stored MetaTrader login credentials.
What this means on the desk
IG's review leaves operators without a published order count or an estimate of the impact. Teams will need to establish which fills require examination and how any resulting adjustments should be reflected in customer records and risk controls.
Until the broker provides more detail, useful questions include what triggers direct contact with a client, whether affected executions can be reconciled against intended orders, and how any required action will be communicated. Processing has resumed, but the size of the review workload remains unknown.
The reported faults involve different parts of a broker's service: execution, logins, position controls, withdrawals and hosting environments. The accounts do not establish a shared cause. Operations teams can check which internal owners handle each path and how client communications and trade reviews are coordinated when a disruption crosses those boundaries.
