In a new report published by Citigroup, the stablecoin market is projected to expand in the coming years, potentially reaching $4 trillion by 2030.
The bank notes that under an optimistic scenario, the issuance volume of stablecoins could hit $4 trillion, while under a base-case scenario, it may reach around $1.9 trillion.
This projection is based on the current growth pace of stablecoins. At the beginning of 2025, the issuance volume was approximately $200 billion, which has quickly grown to $280 billion. Citi notes that if this rapid growth continues, annual transaction volumes could reach as high as $200 trillion.
Blockchain Adoption Drives Stablecoin Growth According to Citi’s analysis, stablecoins will significantly expand their use in the financial system once their velocity approaches levels similar to fiat currencies. In this context, by 2030, the base-case scenario estimates an annual transaction volume of $100 trillion, while the optimistic scenario could see this figure double.
The report views this momentum as a milestone for blockchain technology, describing it as the “ChatGPT moment for blockchain.” Digital-focused companies are accelerating adoption by increasing real-economy usage of stablecoins, highlighting the growing role of stablecoins in traditional financial systems.
