At present, the benchmark interest rate of banks is 6.56%. Due to the tightening of the financial line this year, every bank will increase the intermediary business income and expenses by a certain percentage on the basic interest rate, which is generally between 15-60%, but yours has gone up by 90%, that is, it has gone up by 90% on the basis of 6.56%. This ratio is too high and unreasonable, but it is legal, depending on whether you recognize it or not.
