Does supplied collateral earn interest? Read the market accounting

Key facts
| Fact | Detail | Source |
|---|---|---|
| Aave supply | Supplied tokens accrue the reserve’s supply rate under Aave’s rules. | [1] |
| Morpho collateral | The cited Blue collateral accounting is asset-based and earns no lending yield. | [2] |
| Separate mechanism | Yield-bearing tokens can represent returns generated by another protocol. | [3] |
Identify where the income would come from
Imagine depositing token A into an Aave reserve that has a positive supply rate and enabling it as collateral. Its supply claim can accrue that rate. Depositing A solely as collateral in a Morpho Blue market is a different action; borrowers of the loan asset are not paying lending interest to that collateral balance.
The same token symbol does not make the two positions economically identical.
A yield-bearing token adds another layer
If the collateral token itself represents a growing claim on an external strategy, that underlying mechanism may continue according to its own rules. Separate its return from any lending interest the collateral market pays. A rebasing token, wrapper or reward program also needs compatibility with the market’s accounting.
Compare income and borrowing cost separately
Even where collateral earns something, the debt has its own cost and currency exposure. Record supplied balance, yield source, debt balance and rate independently. Expected income is not a reason to ignore liquidation, oracle or underlying-token risk.

Questions people ask
Does switching an asset on as collateral create a new yield source?
Not by itself. It changes borrowing eligibility; the source of any yield depends on the supply or token mechanism.

The answer and key facts have stable claim links. These records retain the scope and qualification when reused.
Collateral does not earn interest merely because it backs a loan. Aave supplies can accrue pool interest while eligible supplies also serve as collateral. Morpho Blue separates loan-asset lending from collateral deposits, and its collateral balance does not earn Morpho lending interest. A collateral token can still have its own independent yield mechanism.
