The London Interbank Offered Rate, or LIBOR, is the interest rate central banks in London are charged for short-term borrowing.
An interest rate cap is used to limit the risk on a floating rate commercial property loan. A floating rate property loan has a variable interest rate, borrowers usually opt for this type of loan during periods of low-interest rates, because if the interest rate decreases further than the borrower benefits. A floating interest rate can also increase and that may be a huge financial risk if it increases rapidly or by too much. For this reason, borrowers try to cap the amount by which interest on the loan increases.
