Credit rating is an analysis of the credit risks associated with a financial instrument or entity. It assesses the creditworthiness of a borrower based on their financial statements and past borrowing and lending. Credit ratings are assigned by agencies and the rated entity pays for the rating. Securitization of debt involves converting long-term illiquid assets like loans into marketable securities that can be traded, through special purpose vehicles registered with regulatory bodies. It allows lenders to enforce security interests by taking possession of collateral in the event of a default.
