Citigroup’s Institute for Global Perspectives & Solutions (GPS) released its September 2025 report, “Stablecoins 2030: Web3 to Wall Street,” marking one of the most comprehensive institutional analyses of on-chain money to date. The report underscores how stablecoins have evolved from crypto utilities to core components of global financial infrastructure, and cites Allium alongside Visa as data providers tracking this transformation.

Stablecoins enter the institutional mainstream

Citi’s analysts—Sophia Bantanidis, Ryan Rugg, Ronit Ghose, and colleagues—now forecast stablecoin issuance of $1.9 trillion (base case) and $4.0 trillion (bull case) by 2030. At today’s observed velocity assumptions, that could support ≈$95–200 trillion in annual transaction activity. The report frames 2025 as blockchain’s “ChatGPT moment” for institutional adoption: stablecoins are no longer niche—they’re 24×7 liquidity rails with programmability.

The report characterizes 2025 as blockchain’s “ChatGPT moment” for institutional adoption, noting that stablecoins are no longer a niche product for crypto trading but a new rail for 24 × 7 liquidity and programmable settlement.

Allium and Visa data sheds light on stablecoin transactions vs. traditional payments

In its section on “Surge in Stablecoin Supply,” Citi integrates transaction data from Allium and Visa’s public on-chain dashboard to contextualize stablecoin flows relative to traditional payment networks like Fedwire, ACH, Mastercard, and Visa's own network.

“See Visa’s analysis of stablecoin transactions publicly available on visaonchainanalytics.com – the adjusted transaction volume data are based on methodology agreed by Visa and partners … to remove potential distortions in the data created from activity such as high-frequency trading and bots.”
— Citi GPS: Stablecoins 2030, p. 17

Using Allium’s adjusted on-chain data alongside traditional rails, Citi shows stablecoin transaction volumes approaching roughly $1 trillion per month—now beginning to rival traditional payment networks in scale.

A turning point for on-chain finance and data transparency

Citi’s Stablecoins 2030 report positions stablecoins at the center of a new era in digital money—where tokenized assets, digital deposits, and blockchain-based payment rails begin to converge. As Citi notes, stablecoins are “not just speculative instruments, but infrastructure for real-time money movement.”

The report’s use of Allium’s analytics—alongside Visa and other institutional data sources—signals a broader shift: on-chain transparency is becoming part of the standard evidence base for how value moves globally.

Even a single reference carries weight—it reflects how credible, normalized blockchain data is shaping institutional research and how the next generation of financial systems will be built: transparent, interoperable, and data-driven.
