Key Takeaways
- • Citibank revised its 2030 stablecoin issuance forecast upward to $1.9 trillion in base case and $4 trillion in bull case, up from prior estimates of $1.6 trillion and $3.7 trillion, reflecting faster-than-expected market expansion.
- • Stablecoin supply surged from approximately $200 billion at the start of 2025 to $280 billion as of May 2026, demonstrating accelerating adoption driven by digitally native companies entering real-world commerce.
- • At stablecoin velocity rates comparable to fiat currencies, the market could support $100 trillion in annual transactions by 2030 under base scenario and $200 trillion under bull case, positioning stablecoins as meaningful infrastructure for on-chain finance.
- • Bank tokens and tokenized deposits may ultimately achieve higher transaction volumes than stablecoins by 2030, driven by corporate demand for regulatory compliance, real-time settlement, and embedded safeguards, potentially exceeding $100 trillion in annual turnover.
- • The forecast positions multiple forms of digital money—stablecoins, bank tokens, and CBDCs—as coexisting rather than competitive, with the U.S. dollar remaining the dominant denomination while Hong Kong and the UAE emerge as experimental hubs.
Summary
Citibank has significantly raised its medium-term stablecoin market projections, revising its 2030 base case forecast to $1.9 trillion in circulating stablecoin issuance and its bull case to $4 trillion, representing increases of $300 billion and $300 billion respectively from prior estimates. The upward revision reflects accelerating real-world adoption, with stablecoin supply growing from approximately $200 billion at the beginning of 2025 to $280 billion as of May 2026—a 40 percent increase in roughly 16 months.
Citi's analysis frames this expansion as part of blockchain's "ChatGPT moment," wherein digitally native companies such as payment processors and technology platforms are integrating stablecoins into consumer-facing commerce at scale. If stablecoins circulate at velocity rates comparable to traditional fiat currencies, the bank projects they could facilitate $100 trillion in annual transactions under the base case scenario and $200 trillion in the bull case, substantially exceeding current payment system volumes.
However, the forecast introduces an important nuance: bank tokens—including tokenized deposits and regulated institutional instruments—may ultimately capture greater transaction volumes than stablecoins by decade's end. Corporate demand for embedded compliance, real-time settlement finality, and regulatory safeguards positions bank tokens to achieve turnover potentially exceeding $100 trillion annually. This projection suggests the on-chain financial infrastructure will not be dominated by a single asset class but rather shaped by complementary instruments serving distinct use cases.
The analysis underscores the durability of dollar hegemony in digital finance, with most on-chain money remaining denominated in U.S. dollars and supporting elevated demand for Treasury instruments. Simultaneously, geographic diversification is emerging, with Hong Kong and the UAE establishing themselves as centers of blockchain finance experimentation. Citi's framing positions the stablecoin phenomenon not as a threat to traditional banking but as a foundational reshaping of financial plumbing, where stablecoins, bank tokens, and central bank digital currencies coexist within a modernized infrastructure serving different market participants and use cases.
