BREAKING DOWN 'Marginal Lender'
A marginal lender should not be confused with a margin lender, which is a brokerage that lends money to investors who wish to make trades with borrowed funds. The investors put up securities they already own as collateral. Investing on margin is considered quite risky because it amplifies investment losses.
