Reserve yield
Tether receives value when USDT is issued and invests much of its reserve portfolio in short-duration instruments such as Treasury bills.
The interest earned on those reserves is the central driver of the business model because holders generally do not receive that yield.
When customers redeem tokens, the corresponding reserve assets may need to be converted into cash and returned through the issuer's process. Treasury yields change with interest rates and reserve composition, so income from this source can rise or fall over time.
Additional income
Tether can earn from issuance and redemption fees, secured lending and changes in the value of assets such as gold and Bitcoin.
These sources are smaller or more variable than reserve interest and may introduce additional market or credit exposure.
Fees can depend on transaction size, account eligibility and current issuer terms, while secured lending introduces borrower and collateral risks. Gains on other assets can fluctuate and should not be confused with recurring income from high-quality liquid reserves.
Tether versus a bank
Tether issues a token designed for redemption, while a traditional bank takes deposits, lends funds and operates within a deposit-insurance system.
USDT holders should not assume that holding the token provides the same protections as a bank deposit.
Bank deposits may qualify for protections that do not apply to a privately issued stablecoin, and the redemption process is not identical to withdrawing a bank balance. The token's usability and legal rights depend on issuer terms and the user's ability to access official redemption channels.
Risk and transparency
Profitability can strengthen an issuer's capital cushion, but it does not remove reserve, redemption, regulatory or operational risk.
Users should review attestations, reserve composition, redemption access and jurisdictional restrictions before treating a stablecoin as cash-equivalent.
Review who prepared a disclosure, which assets and liabilities it covers and how often it is updated. Users should also consider custody arrangements and redemption limitations, since a profitable business can still face liquidity or operational stress.
