The world of financial trading and securities clearing is poised for dramatic transformation, according to a new survey published by Citi. The report, which surveyed 537 industry leaders from across the globe, suggests that emerging technologies such as stablecoins, asset tokenization, and generative artificial intelligence (GenAI) are on the verge of disrupting the post-trade processing ecosystem—potentially rewriting the rules for how securities are cleared and settled.

Understanding Post-Trade: The Backbone of Financial Markets

Post-trade refers to all processes that occur after a trade is executed, including clearing, settlement, and the management of associated risks. Traditionally, these stages are complex and can expose market participants to operational risks, settlement delays, and increased costs. Modernizing these infrastructures has gained urgency as global trading volumes rise and new asset classes emerge.

Highlights from Citi’s 2025 Survey

Citi’s recent survey finds that over half of respondents expect either tokenization or digital currencies—particularly stablecoins tied to currencies like the US dollar—to accelerate the settlement process within the next five years. Further, with the U.S. and other markets now transitioning to a T+1 (trade date plus one day) settlement standard, efficiency and speed have become crucial priorities.

• Tokenization: 61% of surveyed leaders said blockchain-driven asset tokenization will be integral to post-trade changes by 2030.
• Stablecoins: 54% foresee stablecoins—cryptocurrencies pegged to traditional assets like USD, EUR, or government bonds—playing a central role in real-time settlement.
• Generative AI: 41% believe GenAI could streamline reconciliation, fraud detection, and compliance tasks, accelerating the back-office transformation.

These findings reflect mounting optimism for digital transformation, especially among banks, asset managers, and fintech platforms. As the capital markets landscape shifts, institutions are racing to invest in digital asset infrastructure or partner with technology providers that can deliver these efficiencies at scale.

Stablecoins: The Next Frontier for Settlement

Stablecoins, such as USDC and EURC, have rapidly become a cornerstone for digital payments and settlement. In recent years, the combined market capitalization of major stablecoins has exceeded $160 billion, and their monthly transaction volume now surpasses $1 trillion, according to data from CryptoCompare and The Block (mid-2025).

Stablecoins are gaining support among financial institutions and regulators alike. For instance, companies like Visa and PayPal are piloting stablecoin settlements for cross-border transactions, aiming to cut costs and enable near-instant transfers. In July 2024, the UK Financial Conduct Authority announced advanced guidance to integrate stablecoins into wholesale payments. Meanwhile, in the U.S., pending legislation seeks to clarify regulatory standards around stablecoin issuance and oversight.

These actions suggest that stablecoins could soon serve as the default Rails for financial clearing—not only for crypto markets but also for equities, fixed income, and commodities trading.

Tokenization: Unlocking New Asset Classes and Efficiencies

Tokenization refers to converting ownership rights in real-world assets—equities, bonds, real estate, or even commodities—into digital tokens on a blockchain. Citi’s survey found that industry leaders anticipate a $16 trillion tokenized asset market by 2030, with pilot projects already underway among organizations such as JP Morgan, BlackRock, and Switzerland’s SIX Digital Exchange.

Beyond faster settlement, tokenization enables fractional ownership, broadens access to diverse investor bases, and enhances transparency by recording every transaction immutably. According to the Bank for International Settlements (BIS), tokenized government bond pilots executed on blockchain cut clearing times from days to minutes, potentially reducing counterparty risk across the system.

Generative AI: The Back-Office Revolution

Generative AI, or GenAI, is also making significant inroads in the securities industry. With advances in large language models, GenAI can automate reconciliation of trades, flag suspicious transactions, facilitate regulatory reporting, and answer compliance queries in real time.

In Citi’s analysis, nearly half of surveyed executives say that AI-enabled platforms for post-trade processing will deliver substantial savings in labor and error reduction by 2027. Firms such as Nasdaq and HSBC have already announced collaborations with leading AI providers to modernize their post-trade infrastructure using these tools.

Accelerating Global T+1 Adoption

The U.S. securities market moved to T+1 settlement in May 2024, a change mirrored by Canada and Mexico, with other major markets likely to follow. This regulatory push, designed to contain settlement risk and liquidity demands, is putting additional pressure on back-office teams and is a catalyst for investment in automation and blockchain integration. According to SIFMA, the move to T+1 could free up $5–7 billion in capital and significantly lower counterparty risk annually.

Challenges to a Smooth Transition

Despite the promise of these technologies, hurdles remain. Regulatory uncertainty persists in several regions around how digital assets and stablecoins should be managed, with contrasting approaches from the U.S. SEC, the EU, and Asia. Data privacy, interoperability, and the complexity of integrating new systems with legacy platforms are serious considerations.

Furthermore, banks must train personnel, calibrate risk models for novel assets, and ensure cybersecurity in a world of programmable money—all while facing tight implementation deadlines for new settlement standards.

Looking Ahead

The convergence of stablecoins, tokenization, and AI puts global financial markets at the cusp of a transformative decade. As Citi’s report indicates, forward-thinking institutions are already investing in this future—seeking not only cost efficiencies and faster settlements, but also enhanced transparency, inclusivity, and resilience against systemic shocks.

The winners in post-trade may well be those who can integrate stablecoins and AI the fastest, forging digital highways for global capital while remaining compliant with evolving regulatory frameworks.
