BNET Business Dictionary

Business Definition for: Margining

  • the system by which the London Clearing House (LCH) controls the risk associated with a London International Financial Futures and Options Exchange clearing member's position on a daily basis. To achieve this, clearing members deposit cash or collateral with the LCH in the form of initial and variation margins. The initial margin is the deposit required on all open positions (long or short) to cover short-term price movements and is returned to members by the LCH when the position is closed. The variation margin is the members' profits or losses, calculated daily from the marked-to-market-close value of their position (whereby contracts are revalued daily for the calculation of variation margin), and credited to or debited from their accounts.
