What is typically offered as a valuable asset to secure a loan?

A valuable asset offered to secure a loan is known as collateral. When a borrower provides collateral, they are essentially pledging an asset—such as a car, property, or savings account—that the lender can claim if the borrower defaults on the loan. This reduces the lender's risk since they have a tangible asset they can seize to recover their losses.

Revolving credit, on the other hand, refers to a credit line that can be used repeatedly up to a certain limit, such as credit cards, but it does not involve securing a loan with an asset. Installment credit consists of loans that are repaid in fixed monthly payments over a specified term, often not requiring collateral unless it’s a secured loan. "Economy" doesn't relate to the context of securing a loan; it refers to the system of production and consumption of goods and services in a particular area. Therefore, collateral stands out as the correct answer in this context as it directly pertains to securing a loan with an asset.
