In order to ensure the safety of fund assets, the fund is required to operate according to the principle of asset management and custody, and a special fund custodian is required to keep the fund assets.

The responsibility of the custodian bank is to ensure the safety of the fund assets.

Therefore, during the product holding period, in addition to paying wages to the fund company, it is also necessary to pay wages to the custody bank, which is the custody fee.

Like the management fee, the custody fee is also accrued daily, and the fund company has deducted these fees when publishing the net value, so investors will not have an intuitive feeling.

Compared with management fees, custody fees are relatively cheap.

With the homogenization of fund companies' products becoming more and more serious, the cognitive level of superimposed investors has improved, and some fund companies have broken industry practices and started to cut prices. For example, some index funds have started the low-rate model of "0./kloc-0.5% management fee +0.05% custody fee".

Ping An Fund, Yin Hua Fund, Huaxia Fund, Bosera Fund, E Fund, Fuguo Fund, China Post Fund, harvest fund Fund and Huatai Bairui Fund adopted the rate model of "0./kloc-0.5% management fee +0.05% custody fee" for some of their index funds.

For money funds and index funds, which have low requirements for fund managers or have no obvious difference in performance, saving is earning.

Therefore, like money funds, we should choose the lowest of the three fees (management fee, custody fee and sales service fee), and when tracking different funds of the same index, management fee and custody fee are also very important factors to consider.
