Inside Bank Wealth Management Valuation Systems: Why Wealth Management Products Are 10 Times More Complex Than Funds#
From Non-standard Assets, Amortized Cost Accounting to Fair Value Transition#
When investors buy a mutual fund, they usually see a simple number:
NAV:
1.3526The assumption is:
The market closes, the fund calculates its NAV, and the value is published.
But bank wealth management products historically worked very differently.
For many years, bank wealth management products:
- Did not publish daily net asset values;
- Used expected return models;
- Held large amounts of non-standard assets;
- Relied heavily on amortized cost valuation;
- Depended on bank credit and implicit guarantees.
After China’s asset management regulatory reform, wealth management products entered the:
Net Asset Value (NAV) era.
Banks were forced to build valuation systems similar to investment funds.
However:
Bank wealth management valuation is much more complicated.
The reason:
The assets inside wealth management products are far more diverse than those inside public funds.
1. The Biggest Difference Between Fund Valuation and Wealth Management Valuation#
A typical mutual fund:
Stock
↓
Exchange Price
↓
Valuation
↓
NAVThe asset has a transparent market price.
A bank wealth management product may hold:
Equities
Bonds
Interbank Assets
Non-standard Debt Assets
Trust Products
Asset Management Plans
Bank Deposits
Private Debt
ABS
Income RightsMany of these assets:
do not have publicly traded prices.
Therefore:
Fund valuation is mainly:
Market Price DrivenBank wealth management valuation is:
Market + Model + Contract DrivenIt depends on:
- Market data;
- Valuation models;
- Contract terms.
2. Historical Valuation Model of Bank Wealth Management#
2.1 Expected Return Model Era#
Historically:
A customer purchased:
Product A
Term:
365 days
Expected Return:
5%Internally, the bank focused on:
Asset Income
-
Funding Cost
=
Profit MarginThe product did not necessarily calculate daily fair value.
2.2 The Pooling Model#
A common historical structure:
Multiple Wealth Products
↓
Asset Pool
↓
Unified Investment
↓
Centralized ManagementThe problem:
Investors did not know:
Which exact assets their money was invested into.
Example:
Product A:
100 billion RMBProduct B:
50 billion RMBTogether:
150 billion RMB Asset PoolInvested into:
Bonds
Loans
Trust Products
Non-standard AssetsThis created a separation between:
Investor Product
and
Underlying Assets3. Why Regulatory Reform Forced Valuation System Transformation#
The core requirement:
Net Asset Value Transformation#
Each product must know:
What assets do I own?
↓
How much are these assets worth today?
↓
What is my NAV?Therefore banks started building:

What Are Non-standard Assets?#
Non-standardized debt assets are assets that are not publicly traded.
Example:
Corporate financing:
Company A
borrows:
10 billion RMB
Term:
3 years
Interest Rate:
6%A stock has:
Real-time market priceA private loan does not.
The system must answer:
What is this loan worth today?
6. How Are Non-standard Assets Valued?#
The common method:
Discounted Cash Flow Model (DCF)#
Formula:
Asset Value
=
Discounted Future Cash FlowExample:
Loan:
Principal:
10 billion RMB
Interest:
6%
Term:
3 years
Future cash flow:
Year 1:
600 million interest
Year 2:
600 million interest
Year 3:
10.6 billion repaymentThe valuation engine considers:
Market Interest Rate
Credit Risk
Duration
Liquidity AdjustmentThen calculates:
Today's Fair Value7. Internal Data Model of Non-standard Asset Valuation#
A non-standard asset object may contain:
ASSET_ID
Asset Type
Borrower
Principal
Interest Rate
Start Date
Maturity Date
Repayment Method
Credit Rating
Cash Flow ScheduleCash flow table:
CASH_FLOW_SCHEDULEExample:
| Date | Amount |
|---|---|
| 2027-01-01 | 600 million |
| 2028-01-01 | 600 million |
| 2029-01-01 | 10.6 billion |

Asset Value8. Why Did Banks Prefer Amortized Cost?#
Historically, banks preferred:
Amortized Cost Accounting#
Because:
It creates stable returns.
Example:
Bond purchase:
Price:
100 RMBCoupon:
5%Maturity:
5 yearsThe system gradually recognizes value over time.
NAV appears smooth:
1.001
1.002
1.003For customers:
The product looks stable.
9. The Problem With Amortized Cost#
The problem:
It may hide market risk.
Example:
Bank purchases a bond:
Purchase Price:
100 RMBOne year later:
Market price:
80 RMBFair value:
80 RMBAmortized cost:
Still close to:
100 RMBThe accounting value does not immediately reflect the market loss.
This creates:
valuation lag.
10. Why Fair Value Became the Future#
Fair value means:
Every day:
Assets are revalued using current market information.
Example:
Bond:
Yesterday:
100 RMBToday:
98 RMBNAV reflects:
-2%Advantages:
- Transparent;
- Risk visible;
- Market-driven.
Disadvantage:
- Higher volatility.
11. How Does the System Switch Between Amortized Cost and Fair Value?#
This is one of the biggest technology changes.
The same asset may require different valuation methods.
Example:
Bond:
VALUATION_METHOD
AC
or
FVDatabase table:
ASSET_VALUATION_RULEContains:
Asset Type
Valuation Method
Conditions
Effective Date
Expiration DateRule example:
IF
Asset_Type = Bond
AND
Holding_Model = Collect_Cash_Flow
THEN
Amortized CostOtherwise:
Fair Value12. Why Is Wealth Management Valuation Much More Complex Than Fund Valuation?#
Reason 1: More Asset Types#
Funds:
Stocks
Bonds
CashWealth management:
Stocks
Bonds
Loans
Trust Products
ABS
Non-standard Assets
Deposits
DerivativesReason 2: More Valuation Models#
Funds mainly use:
Market PriceWealth management requires:
DCF Models
Credit Models
Yield Curves
Risk AdjustmentsReason 3: Contract-driven Assets#
A loan is not a standardized security.
Each contract has:
Interest Rate
Maturity
Repayment Schedule
Prepayment ConditionsA stock:
Same code.
Same market price.
13. Core System Changes After Establishing Wealth Management Subsidiaries#
Banks created dedicated wealth management companies.
They needed:
Investment System
↓
Portfolio Management System
↓
Valuation Platform
↓
Risk System
↓
Accounting System
↓
TA SystemBut compared with funds, they also require:
Non-standard Asset Platform
Credit Rating Engine

Especially for:
Non-standard assets.
AI can assist:

Cash Flow Prediction
Risk AdjustmentConclusion#
The complexity of bank wealth management valuation is not because the formula is difficult.
The difficulty comes from the question:
Fund valuation asks:
“What is the market price of my assets today?”
Bank wealth management valuation asks:
“How much are these assets worth when many of them have no public market price?”
Therefore, the system must combine:
Market Prices
+
Contract Cash Flows
+
Credit Risk
+
Accounting Rules
+
Regulatory RequirementsThe final architecture becomes:
