Inside China’s Financial Valuation Architecture: Data Flow Between Valuation Engines, Market Data, ChinaBond Pricing, Accounting Systems and Custodian Review#
In the asset management industry, one of the most important but least visible systems is the:
Valuation System.
Trading systems answer:
What assets were bought?
TA systems answer:
Who owns how many units?
Clearing systems answer:
How are money and securities settled?
But valuation systems answer:
How much are those assets worth today?
Every day, when mutual funds, wealth management products, brokerage asset management products, and trust products publish their NAV, the number is produced by a valuation infrastructure running behind the scenes.

Large financial institutions usually build valuation platforms with:
Data Input Layer

Market Data Platform
↓
Valuation Engine
↓
Accounting System

Custodian Verification

NAV PublicationMain components:
| Component | Function |
|---|---|
| Market Data Source | Provides prices and reference data |
| Valuation Engine | Calculates asset values |
| Valuation Rules Engine | Defines calculation methods |
| Accounting System | Generates financial records |
| Custodian System | Independent verification |
| NAV System | Publishes investor-facing values |
3. The First Layer: Market Data Sources#
The first requirement for valuation is:
A reliable price source.
Stocks have transparent prices.
But what about:
- Bonds?
- Private equity?
- Trust loans?
- Real estate assets?
- Non-standard credit products?
Financial institutions need multiple pricing sources.
4. Equity Market Data#
For listed stocks:
Sources include:
Shanghai Stock Exchange
Shenzhen Stock Exchange
Market Data VendorsData fields:
Security Code
Closing Price

Equity Valuation5. Bond Valuation and ChinaBond Pricing System#
Bond valuation is much more complicated than stock valuation.
Why?
A stock normally has:
One market priceA bond requires:
Face Value
Coupon Rate
Maturity
Yield Curve
Credit Risk
Liquidity AdjustmentTherefore Chinese financial institutions widely use:
ChinaBond Valuation System#
It serves:
- Banks
- Mutual funds
- Insurance companies
- Wealth management subsidiaries
- Brokerage asset managers
6. What Exactly Is ChinaBond Valuation?#
A common misunderstanding:
ChinaBond valuation is simply the bond trading price.
It is not.
It is closer to a professional pricing model.
Example:
Corporate bond:
Face Value:
100 RMB
Coupon:
4%
Maturity:
3 yearsNo market transaction happens today.
The system calculates:
Theoretical Value:
101.25 RMBBased on:
Market Transactions
Yield Curves
Credit Rating
Remaining Duration
