Definition:
A "participation loan" is a type of loan that is shared by a group of banks. These banks come together to lend money because the amount of money needed is too large for just one bank to provide alone.
In finance, participation loans are useful for spreading risk among several lenders. Each bank involved in the loan takes a part of the loan amount and shares the responsibility of repayment.
While "participation loan" specifically refers to a banking term, "participation" in general can refer to being involved in any activity, such as a participation in a game or meeting.
A participation loan is a financial agreement where multiple banks come together to lend a large amount of money that would be too risky or too large for one bank to handle alone.
