There is no clear definition of cash wealth management products, so different types of cash wealth management products have great differences in risk and liquidity, such as funds, trusts and banks. People can choose investment according to their different needs, which is suitable for investors with smaller investment scale. Generally, the higher the liquidity of cash financing, the lower the income. For example, the bank's time deposits and deposit interest rate are higher, while the interest rate of call deposits will be higher than that of demand deposits. The higher the interest rate, the lower the liquidity.
