Ques:- Explain bank guarantees? How do they work?
Right Answer:
A bank guarantee is a promise made by a bank to cover a loss if a borrower fails to fulfill their contractual obligations. It acts as a safety net for the party receiving the guarantee.

The borrower typically pays a fee to the bank for this service. If the borrower fails to meet their obligations, the beneficiary can claim the amount from the bank, which will then seek reimbursement from the borrower.
