Inside China’s Financial Valuation Systems: How Brokers, Banks, Trusts, Funds, Wealth Management Subsidiaries and Custodians Calculate Asset Values#
When investors look at a financial product, they usually see only one number:
Net Asset Value (NAV)
1.0523
or
1.0541It appears simple:
NAV = Total Assets - Total Liabilities
-----------------------------
Total Fund UnitsHowever, behind this number exists a complete financial technology ecosystem:

A public mutual fund, a bank wealth management product, a trust plan, and a brokerage asset management product may all publish “net value”, but their valuation logic and technology architecture are fundamentally different.
1. What Is a Valuation System?#
A valuation system answers one fundamental question:
How much are all assets inside this financial product worth today?
Example:
A fund owns:
Stocks:
1 billion RMB
Bonds:
500 million RMB
Cash:
100 million RMBLiabilities:
Management fees
Custody fees
Transaction costsNet assets:
Total Assets - Total LiabilitiesFund units:
1 billion unitsNAV:
1.6 RMB per unitThe calculation sounds simple.
The difficulty is determining the value of each asset.
2. Why Valuation Is Difficult#
Some assets have transparent prices:
Example:
Listed stock:
Shanghai Stock Exchange closing price
↓
Market valueEasy.
But many assets do not have real-time market prices.
Examples:
Corporate bonds
Private equity
Trust loans
Real estate assets
Asset-backed securities
Non-standard credit assetsThe valuation system must decide:
What price should be used?
What model should be applied?
Who verifies the result?3. Major Participants in China’s Valuation Infrastructure#

A fund company cannot both:

A custodian bank does not simply store money.
It performs several key functions.
Asset Custody#
Example:
Fund company claims:
We own 1 million sharesCustodian verifies:
Securities account actually contains 1 million sharesCash Supervision#
Ensures:
Assets cannot be moved improperlyValuation Review#
Checks:
