Legal Definition
Cash collateral refers to a specific type of security or asset that is pledged by a borrower (debtor) to secure a loan, bond, or obligation, where the value of the cash itself is used as the underlying asset for the collateral, rather than a more traditional fixed asset like real estate. In essence, it signifies that the lender has taken possession of the actual physical currency or liquid assets from the borrower to ensure repayment of a debt.
Plain-English Translation
Imagine you need a loan, and instead of just giving the bank a piece of land, you give them the actual money in your pocket. This money is what's called 'cash collateral.' It means the lender has the right to take that cash as security for the loan. So, if you borrow money, the lender takes the physical cash because it's the asset backing the loan.
