The monthly yield on residential mortgage loans (total) is a weighted average yield on the total of all types of loans (floating and fixed) for registered banks fully secured on residential property. We calculate it using the sum of each bank’s interest income received for both floating and fixed residential mortgage loans compared to the sum of a 2-period moving average of the value of these loans. Using a 2-period moving average for the value of loans takes into account that not all loans at the end of the reporting period would have contributed to the interest income over the reported month.
The yield takes into account the number of days within each month and is annualised. Each yield is calculated as follows:
Yield = (The sum of each bank's interest income received on loans / The sum of a two period moving average of the value of loans) X (365 / number of days in a month) X 100
The monthly yield on residential mortgage loans (floating) is a weighted average yield on the total of all floating rate loans for registered banks fully secured on residential property.
We calculate it using the sum of each bank’s interest income received for floating residential mortgage loans compared to the sum of a 2-period moving average of the value of these loans. Using a 2-period moving average for the value of loans takes into account that not all loans at the end of the reporting period would have contributed to the interest income over the reported month.
The yield takes into account the number of days within each month and is annualised.
See ‘Yield on residential mortgage loans (total)’ above for the calculation formula.
The monthly yield on residential mortgage loans (fixed) is a weighted average yield on the total of all fixed rate loans for registered banks fully secured on residential property.
We calculate it using the sum of each bank’s interest income received for fixed residential mortgage loans compared to the sum of a 2-period moving average of the value of these loans. Using a 2-period moving average for the value of loans takes into account that not all loans at the end of the reporting period would have contributed to the interest income over the reported month.
The yield takes into account the number of days within each month and is annualised.
See ‘Yield on residential mortgage loans (total)’ above for the calculation formula.
The monthly yield on total business loans is a weighted average yield on the total of all business loans for registered banks (not fully secured by residential property).
We calculate it using the sum of each bank’s interest income received for total business loans compared to the sum of a 2-period moving average of the value of these loans. Using a 2-period moving average for the value of loans takes into account that not all loans at the end of the reporting period would have contributed to the interest income over the reported month.
The yield takes into account the number of days within each month and is annualised.
See Yield on residential mortgage loans (Total) above for the calculation formula.
The monthly cost of total deposits is a weighted average cost on the total of savings (call) accounts and term deposits for registered banks.
It is calculated using the sum of each bank’s interest expenses paid for both savings (call) accounts and term deposits compared to the sum of a two period moving average of the value of these deposits. Using a two period moving average for the value of deposits takes into account that not all deposits at the end of the reporting period would have contributed to the interest expenses over the reported month.
The cost takes into account the number of days within each month and is annualised. Each cost is calculated as follows:
Cost = (The sum of each bank’s interest expenses paid on bank deposits / The sum of a two period moving average of the value of deposits) X (365 / number of days in a month) X 100
The monthly cost of savings (call) accounts is a weighted average cost on the total of savings (call) accounts for registered banks.
It is calculated using the sum of each bank’s interest expenses paid for savings (call) accounts compared to the sum of a two period moving average of the value of these deposits. Using a two period moving average for the value of deposits takes into account that not all deposits at the end of the reporting period would have contributed to the interest expenses over the reported month.
The cost takes into account the number of days within each month and is annualised.
See Cost of total deposits above for the calculation formula.
The monthly cost of term deposits is a weighted average cost on the total of term deposits for registered banks.
It is calculated using the sum of each bank’s interest expenses paid for term deposits compared to the sum of a two period moving average of the value of these deposits. Using a two period moving average for the value of deposits takes into account that not all deposits at the end of the reporting period would have contributed to the interest expenses over the reported month.
