First of all, China is still implementing a separate financial operation and supervision system. Icbc itself has no right to operate funds, but only as a consignment channel. And ICBC can sell the funds of N fund companies on a commission basis. So your so-called "money fund of ICBC" is actually problematic, because you bought a certain money fund sold by ICBC. Industrial and commercial bank of China can sell n money funds on a commission basis, and the income of the two is definitely different.

Secondly, the income of the money fund is floating and uncertain, while the deposit interest rate is fixed. You can't directly compare uncertain things with certain things. You can only make a rough forecast based on the recent income trend of a certain money fund and the recent market trend of the money fund, but this is only a forecast.

Third, the money fund's income and the bank's interest rate are both "annualized income". For example, the interest rate of ICBC's half-year fixed deposit is 3% (which should be the result of floating), so if you deposit for half a year, will it be calculated according to the interest rate of 1.5%? The annualized income is specific days /365. So I won't say that I will only give you half the interest rate, which is not my understanding.

Finally, I want to say that you are still very conscious of investment. 20 thousand doesn't seem like a lot of money now, but you should keep it carefully. But you need to learn more basic knowledge of investment and financial management to prevent being fooled.
