In a recent report, Citigroup forecasts that the stablecoin market could expand significantly, potentially reaching $3.7 trillion by 2030. This projection underscores the growing influence of stablecoins in the global financial landscape.

These crypto tokens, typically pegged to fiat currencies like the US dollar, have already seen significant growth. Citi notes that the trend is far from over. Issuers of stablecoins may turn out to be some of the biggest US Treasury buyers. Tether (USDT), for example, was among the top seven holders of US government debt in 2024. By 2030, stablecoin issuers may demand up to $1 trillion in Treasuries to back their coins with safe, liquid assets.
Key Drivers of Growth
Citigroup identifies several factors contributing to the anticipated growth of stablecoins:
- Currency Hedging: A shift from traditional currency holdings to stablecoins for hedging purposes.
- Payment and Cash Management: Increased use of stablecoins for payments and short-term liquidity needs, leveraging blockchain’s efficiency.
- Crypto Industry Expansion: Overall growth in the cryptocurrency sector bolstering stablecoin adoption.
The report also notes that approximately 90% of stablecoins are expected to remain US dollar-denominated, reinforcing the dollar’s global dominance.
Implications for Traditional Banks
While the rise of stablecoins may impact traditional bank deposits, Citigroup suggests that banks can adapt by:
- Providing custodial services for stablecoin reserves.
- Brokering reserve asset purchases, such as U.S. Treasuries, for stablecoin issuers.
- Issuing their own stablecoins and developing new financial products.
These strategies could help banks maintain relevance in an evolving financial ecosystem.
Regulatory Landscape
Citigroup emphasizes the importance of regulatory developments in facilitating stablecoin adoption. Clear guidelines could enhance the appeal of stablecoins and support their integration into the broader financial system.
As the financial industry continues to evolve, stablecoins are poised to play a significant role in shaping the future of global finance.
