The holding company
Monex Group, Inc.
(Japan: 8698.T)
MONEX BOOM has a set of comprehensive risk management policies that is established based on the Monex Group's risk control framework.

The policies set the scope for MONEX BOOM's risk taking and operations. Under the guidelines, we operate only with reputable licensed banks and regulated custodians, and we have no proprietary trading, and no exposure to any structured financial products.


MONEX BOOM's facilitation of client trading requires that client accounts at all times have sufficient collateral (i.e. margin). This measure limits MONEX BOOM's client counterparty risk significantly.


MONEX BOOM's proprietary risk management system is running whenever markets open that allow immediate actions. Margin exposures are calculated in real-time and margin-call alerts are issued automatically to ensure compliance to the policies for market and credit risks.

In additional, credit and trading lines available to selected clients are monitored on real-time basis.
