Margin Ratios

Definition

Margin ratios represent the proportion of an investor’s own capital relative to the total value of a leveraged position in financial derivatives. This metric is critical for assessing risk and determining the amount of collateral required to maintain open positions. It typically includes initial margin, the capital required to open a position, and maintenance margin, the minimum equity needed to avoid a margin call. The ratio directly influences a trader’s leverage and potential for liquidation. It quantifies the level of financial commitment.
