Collateral is a key component of secured lending, providing the lender with a form of protection in case the borrower cannot meet their financial obligations. If the borrower defaults on the loan, the lender can seize the collateral to recover the owed amount. The value of the collateral is an important consideration for the lender, as it needs to be sufficient to cover the loan in case of default. Collateral can take various forms, such as real estate, inventory, financial assets, or equipment.
