Deloitte warns of rising risks in T+0 settlement and asset tokenization; stablecoins may become new financial risks

On January 26, Deloitte issued a major warning in its 2026 Financial Markets Outlook report: As T+0 settlement and asset tokenization accelerate, the global financial system may be entering a new phase that is “faster but less transparent.” If regulation and infrastructure do not upgrade in sync, market manipulation and systemic risks will become harder to detect and contain.

T+0 settlement refers to completing the transfer of funds and assets on the same day, seen as a key next upgrade on Wall Street. Deloitte pointed out that this change is highly related to blockchain assets, stablecoins, and tokenized securities, because only in an instant settlement environment can the advantages of digital assets truly be realized. Once real-world assets like bonds and stocks circulate in token form, transaction steps will be compressed, clearing and reconciliation costs will significantly decrease, and capital turnover efficiency will markedly improve.

However, Deloitte also clearly states that the current financial system still relies on settlement cycles, reconciliation processes, and regulatory reporting. Once settlement speed is greatly increased, the time available for error correction, collateral supplementation, and anomaly detection will also decrease, making operational risks and liquidity shocks more concentrated.

Deloitte executives Roy Ben-Hur and Megan Burns said that tokenization will not reshape the global market overnight but will gradually advance through small-scale pilots. This approach can test technology and examine institutional frictions, but also means that for a considerable period, the same asset will exist in both tokenized and traditional forms. The market must decide which version is more liquid and which price is more authoritative, which could itself trigger new instability.

More notably, T+0 settlement will fundamentally change the operation of collateral and liquidity. In the past, institutions could use settlement delays to allocate cash and securities, but in real-time environments, this buffer is compressed. Deloitte believes this is precisely the scenario where stablecoins and tokenized collateral are most likely to be adopted first, as they can provide settlement tools linked to the dollar that are quickly transferable. U.S. regulators are exploring this direction, aiming to improve collateral management efficiency through blockchain.

However, Deloitte also warns that regulators relaxing some reporting and process requirements to encourage innovation may create new “blind spots.” Faster settlement combined with lower information disclosure could weaken the market’s ability to detect manipulation, verify discrepancies, and identify pressures. In extreme cases, this combination could amplify systemic risks.

Ben-Hur and Burns pointed out that U.S. regulators have already begun to use tools like no-action letters to greenlight tokenization pilots. This approach can quickly promote market evolution but also means some new rules are implemented prematurely without a comprehensive framework. Once liquidity is attracted to faster-settling new blockchain trading environments, traditional price discovery mechanisms may be marginalized.

Deloitte’s conclusion is very clear: Tokenization and T+0 are not marketing concepts but a stress test of infrastructure. If blockchain assets can improve settlement certainty and collateral efficiency without sacrificing transparency, they will become part of mainstream finance after 2026; if fragmentation and information asymmetry worsen, regulatory tightening will come swiftly. T+0 settlement is the key to whether this financial upgrade can truly be realized.
