In UK property development finance, an interest rate floor is a contractual minimum interest rate applied to variable rate loans. It guarantees lenders a baseline return, ensuring the interest charged on development finance does not fall below a certain level even if market rates drop. This protects lenders against excessively low returns but may slightly increase borrowing costs for property developers. For SME developers and industry professionals, understanding interest rate floors is essential, as they directly affect the overall cost of development finance and should be factored into project budgeting and financial planning.
This sits beneath Hedging & Interest Rate Risk Metrics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Interest Rate Cap, as both are closely related measures used to assess similar aspects of performance or risk.
