remargin(redirected from Re-Margining)
To place more cash or securities into a margin account as collateral following a margin call. In a margin call, a brokerage requires a client to remargin because the market value of the collateral currently in the account has fallen below the margin requirement, which is a least 25% (and sometimes 50%) of the value of the securities the client has purchased with borrowed money. Remargining occurs to force the client to comply with federal regulations and/or the brokerage's own rules.
To deposit additional cash or securities in a margin account when equity in the account is judged to be insufficient to meet the maintenance margin requirement.
