The calculation of loan interest adopts floating interest rate, and the interest is adjusted with the adjustment of interest rate. Of course, no matter how it is calculated, it has no effect on the interest paid. Will have an impact on the adjusted interest. After the adjustment of the general bank interest rate, the interest rate of the outstanding part of the loan is also adjusted. There are three forms: first, after the bank's interest rate is adjusted, the newly adjusted interest rate will be implemented at the beginning of the following year (ICBC, Agricultural Bank of China and China Construction Bank are all like this); The second is annual adjustment, that is, the new interest rate is adjusted and implemented every year of repayment (such is the case with China bank mortgage); Third, the two sides agreed that the new interest rate level will generally be implemented in the month after the bank's interest rate adjustment.
No matter how the benchmark interest rate is adjusted, the floating (or falling) range remains unchanged, but it is only floating (or falling) on the basis of the new interest rate.
Brief introduction of floating interest rate:
Floating interest rate refers to the interest rate that is adjusted accordingly with the change of price or other factors during the loan period. Lenders and borrowers can agree that the interest rate can be adjusted with the price or other market interest rates when signing the loan agreement. Floating interest rate can avoid some disadvantages of fixed interest rate, but the calculation basis is diverse and the procedures are complicated.
China's medium-and long-term savings deposit subsidy method is a form of floating interest rate system.
Interest rates can be adjusted at any time according to changes in market interest rates. Common basic interest rate plus calculation. Usually, the loan interest rate or commercial paper interest rate of the most reputable enterprises in the market is set as the basic interest rate, and on this basis, 0.5 to 2 percentage points are added as the floating interest rate. Repay the principal at face value at maturity, and pay interest at floating rate according to the specified interest payment period at ordinary times.
Interest rates set by banks and other financial institutions fluctuate within a certain range around the benchmark interest rate. Above the benchmark interest rate and below the highest range (including the highest range), the interest rate is said to be floating up, below the benchmark interest rate and above the lowest range (including the lowest range), and the interest rate is said to be floating down.
In western countries, the benchmark interest rate is the interest rate used for loans with the least risk and the most liquidity. In the range of the highest and lowest floating interest rates, the interest rates of banks are different. In China, the People's Bank of China authorizes a bank, branch or specialized bank to float within the statutory interest rate level and the prescribed range according to different situations, with the purpose of giving full play to the economic leverage of interest rates, distinguishing normal capital demand from abnormal capital occupation, and combining the leverage of interest rates with the credit principle of "differentiated treatment and preferential support". 1987, the loan interest rate of working capital fluctuated within the range of 20%, and 1988 was expanded to 30%, and the loan interest rate of almost all projects of working capital and fixed assets could rise. 1February, 990, it was stipulated that only the interest rate of working capital loans could rise by 20%. From March 2 1 of the same year, the interest rate of working capital loan can not only go up by 20%, but also go down by 10%, which will be implemented after being approved by the local people's bank. Floating interest rates can be roughly divided into two types. One is the interest rate floating right authorized by the State Council to the head office of the People's Bank of China. Such as energy, transportation, communication, salt industry, agriculture, etc. 13 industries, the interest rate of infrastructure loans falls in three categories 10%, 20% and 30% respectively. The other is that the branches of specialized banks float the loan interest rate within the prescribed scope according to the credit standing and benefit of the enterprises that need loans, so as to promote enterprises to strengthen management, speed up capital turnover and improve economic benefits.
In China, floating interest rate has become an important part of the interest rate system, and the types of implementation are: ① loan interest rate of urban and rural credit cooperatives; (two) the interest rate of working capital loans of specialized banks and other financial institutions (excluding urban and rural credit cooperatives); ③ The rediscount rates of branches of provinces, autonomous regions, municipalities directly under the Central Government, branches of cities under separate state planning and branches of pilot cities for financial system reform can fluctuate by 5-10% according to the same interest rate; (4) Local corporate bonds of all levels can rise by 40% before 199 1 year, and by 20% from 199 1 year; ⑤ Regular, fixed deposit, convenient access and use savings shall bear interest at a discount of 60% for the same period. ⑥ The interest rate of large negotiable certificates of deposit issued by individuals rises according to the interest rate of fixed lump-sum deposits in the same period; ⑦ The interest rates of overdue loans and misappropriated loans rose by 20% and 30% respectively on the basis of the original interest rate.
