Yes "The same period" means that the time of arrears and the applicable time of bank loan interest rate are in the same period. For example, the loan interest rate standard published by the People's Bank of China on July 7, 201/and the new interest rate standard published on June 8, 20 12, then 20 165438+ should be applied when calculating the interest on arrears during this period. You cannot apply before July 7th of 20 1 1 or after June 8th of 20 12, otherwise it will not be the same period. It should be noted that if the benchmark loan interest rate announced by the People's Bank of China changes in the same period, the interest shall be calculated by stages according to the change of interest rate.
