Every tokenized asset transaction has a cash leg: when tokens are purchased, income is distributed, or collateral is posted, there is a payment on the other side of the transaction. In traditional securities markets, this cash leg settles through the banking system — bank transfers, central bank reserves, and the clearing and settlement infrastructure that has been built over decades. In tokenized asset markets, where the securities leg settles on a blockchain at T+0, the cash leg must be on the same blockchain and available at the same time. Stablecoins — digital representations of fiat currency on blockchain — are the mechanism that makes this possible.
Why Stablecoins Are the Settlement Currency of Tokenized Markets
The fundamental reason that stablecoins serve as the settlement currency for tokenized asset transactions is timing compatibility: a blockchain-native securities transaction settles in the same block as the payment, requiring the payment itself to be on-chain at the moment of settlement. Traditional bank transfers are not on-chain and do not settle in real time — they process through correspondent banking networks with settlement delays of hours to days. A tokenized bond that settles at T+0 cannot receive its payment from a traditional bank wire that takes 2-3 days to settle; it must receive payment from an on-chain settlement currency that is available immediately.
Stablecoins bridge this gap by representing fiat currency value on a blockchain: USDC held on Ethereum represents a dollar-denominated claim that can be transferred in the same transaction block as a tokenized security transfer, creating the atomic delivery-versus-payment that makes T+0 settlement possible. Without stablecoins, tokenized securities could be issued and recorded on blockchain but could not settle cash on the same chain at the same time.

The GENIUS Act: The US Institutional Framework
The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act, signed into law in July 2025 after passing the Senate 68-30 in June, establishes the first federal US framework for stablecoin issuance. Key requirements: stablecoins must be backed 1:1 by high-quality liquid assets (US Treasuries, central bank deposits, equivalents); issuers must maintain robust AML/BSA compliance programmes; qualified custodian standards apply to reserve holdings; and the qualified stablecoin issuer designation provides the legal basis for institutional investors to hold and use designated stablecoins within regulated portfolio mandates.
For institutional tokenized asset settlement, the GENIUS Act matters in three specific ways. First, it provides regulatory certainty about which stablecoins institutional investors can use for settlement — qualified GENIUS Act stablecoins have the backing and compliance standards that fiduciary mandates require. Second, it creates a level playing field between bank-issued and non-bank-issued stablecoins, allowing Circle, Ripple, and others to compete with bank deposit tokens on a regulated basis. Third, it positions the US dollar stablecoin as the interim institutional settlement currency until wholesale CBDC is universally available — explicitly recognising that regulated stablecoins serve a legitimate monetary role in digital finance.
The Credit Risk Hierarchy in Stablecoin Settlement
Not all stablecoins carry the same credit risk for institutional settlement purposes. Understanding the credit quality hierarchy is essential for institutional risk managers:
- Lowest credit risk: Wholesale CBDC (central bank money with no counterparty risk — the safest possible settlement currency). Available through BIS mBridge for specific corridors, MAS 2026 SGD pilot. Not universally available.
- Near-lowest credit risk: GENIUS Act-qualified fiat-backed stablecoins (USDC, RLUSD) with 1:1 HQLA backing, qualified custodian, and federal regulation. Counterparty risk is the issuer’s ability to maintain reserves — lower than bank deposits due to HQLA backing requirement.
- Moderate credit risk: Traditional bank deposit tokens (tokenized commercial bank deposits — JPM Coin, tokenized HSBC deposits). Bank credit quality; not HQLA-backed at 1:1. Subject to bank failure risk.
- Higher credit risk: Decentralised algorithmic stablecoins (DAI, GHO) backed by crypto collateral with overcollateralisation rather than HQLA. Smart contract risk and collateral volatility are additional factors. Institutional use typically limited to DeFi-specific transactions where counterparty is the protocol rather than a single issuer.
Cross-Border Stablecoin Settlement
For cross-border tokenized asset transactions — a Bahraini institutional investor subscribing to a UAE-issued tokenized real estate instrument, for example — stablecoin currency matters alongside stablecoin credit quality. A USD stablecoin (USDC or RLUSD) settles the transaction in dollars, creating an implicit FX transaction for investors or issuers in non-dollar jurisdictions. Euro-denominated stablecoins (EURAU, the EIB’s digital euro experiments, MiCA-compliant Euro stablecoins) settle in Euros, eliminating FX friction for EU institutional investors.
The emergence of currency-specific institutional stablecoins — EURAU for Euro settlement (AllUnity/Tradeflow/Obligate, February 2026), the Bahrain CBB’s SIO Framework for BHD stablecoins, and Singapore MAS BLOOM for SGD settlement — expands the cross-border tokenized asset settlement universe beyond dollar-denominated transactions. For platforms like Blockmaze serving cross-border institutional transactions across GCC and EU markets, the availability of BHD and Euro stablecoins under their respective regulated frameworks is directly relevant to the settlement currency landscape for their issuers and investors.
Tokenized Deposits: The Institutional Alternative
Tokenized deposits — digital representations of commercial bank deposits on blockchain (JPM Coin, HSBC’s tokenized deposit experiments, the SWIFT/Ant/HSBC December 2025 cross-border trial) — provide an alternative to third-party stablecoins for institutional settlement. The key difference: a tokenized deposit is a claim on the issuing bank rather than a claim on a reserve asset held by a non-bank issuer. For institutional investors who already have a banking relationship with JPMorgan or HSBC, tokenized deposits within that banking relationship may be preferable to third-party stablecoins for settlement, because they do not require a separate counterparty risk assessment.

Frequently Asked Questions
1. Why must tokenized asset settlement use stablecoins rather than bank transfers?
Tokenized securities settle on-chain at T+0, requiring the cash payment to be available on the same blockchain at the same moment. Traditional bank transfers settle through correspondent banking networks over hours to days — incompatible with T+0 atomic settlement. Stablecoins provide on-chain fiat representation that can settle simultaneously with the securities leg.
2. What does the GENIUS Act require from stablecoin issuers?
1:1 reserve backing with high-quality liquid assets (US Treasuries, central bank deposits); robust AML/BSA compliance programmes; qualified custodian standards for reserve holdings; and the qualified stablecoin issuer designation for federal regulatory recognition.
3. What is the credit risk difference between USDC and JPM Coin?
USDC is backed 1:1 by HQLA (US Treasuries and bank deposits) held in qualified custodians — credit risk is Circle’s ability to maintain reserves. JPM Coin is a tokenized JPMorgan deposit — credit risk is JPMorgan as a commercial bank. USDC’s HQLA backing provides more explicit reserve transparency; JPM Coin benefits from the existing JPMorgan banking relationship for institutional clients.
4. What is EURAU and why does it matter for EU tokenized asset settlement?
EURAU is a regulated Euro-denominated stablecoin launched by AllUnity and integrated with Tradeflow and Obligate in February 2026 for tokenized trade securities settlement. It provides Euro-denominated on-chain settlement, eliminating the FX friction that USD stablecoins create for EU institutional investors in tokenized asset transactions.
5. What is the ultimate institutional settlement currency for tokenized assets?
Wholesale CBDC — central bank digital money that eliminates all private issuer credit risk — is the ultimate settlement currency for institutional tokenized assets. Until it is universally available, GENIUS Act-qualified fiat-backed stablecoins provide the most creditworthy available alternative, with the lowest risk hierarchy below wholesale CBDC.
