Credit risk is the risk resulting from the uncertainty that a borrower or a group of borrowers may be unwilling or unable to meet their contractual obligations as per the agreed terms. It is the largest element of risk faced by most banks and financial institutions. Potential losses due to high credit risk can threaten a bank's solvency.
