Stablecoins will surge into the mainstream economy amid increasing adoption of blockchain technologies, according to a report by Citigroup, a US bank.
Citi: Stablecoins Market Value Could Reach $3.7 Trillion by 2030

The supply of coins tied to the value of traditional currencies has already risen by a factor of 30 during the last five years with Tether (USDT) and the US Dollar Coin (USDC) proving popular. As at April 2025, the market value of stablecoins is over $230 billion, according to the report.
Bullish case
Under Citi’s most bullish case, favourable regulatory support and institutional adoption could propel the total outstanding supply of stablecoins to $3.7 trillion by 2030.
“2025 has the potential to be blockchain’s ‘ChatGPT’ moment for adoption in the financial and public sector, driven by regulatory change.”
The analysts are clearly hedging their bets: their base case prediction is a market of $1.6 trillion, with the bear prediction of only $500 billion if there are persistent regulatory or adoption issues.
Demand for US Treasuries
The report also notes that:
- Regulatory clarity is critical for the current and future stablecoin market, allowing banks and other financial institutions to incorporate these coins into their portfolios and customer offerings.
- A supportive US regulatory framework for stablecoins, eased by the Trump administration’s favourable crypto stance, could significantly increase demand for US Treasuries.
- Crypto is seen as a new asset class, with traditional investors increasingly both buying crypto for their portfolios and offering new crypto-based services to their clients.
