Mortgage interest rate, a term in the field of economics, refers to the loan interest rate in the form of mortgage with real estate.
According to the traditional Keynesian economic thought, when considering the determinants of mortgage interest rate for single housing financing, market economy countries usually regard the loan interest rate as the capital price in the capital market, and think that the loan interest rate should mainly depend on the market supply and demand of mortgage funds.
There are three types of participants in the mortgage fund market: mortgage institutions, borrowers and depositors.
