Global bank Citi has predicted 2025 could be a possible inflection point for blockchain adoption driven by stablecoins

This could lead to greater adoption of blockchain-based money and spur other use cases, financial and beyond, in the U.S. private and public sector

Citi has predicted that 2025 could be a possible inflection point for stablecoin adoption, driving broader blockchain use cases in a development that parallels the breakout year artificial intelligence (AI) had with popular application ChatGPT.

At the center of the Citi's projection are stablecoins, a class of cryptocurrencies pegged to traditional currencies like the U.S. dollar. These tokens, led by Tether's $145 billion USDT and Circle's $60 billion USDC, have seen tremendous growth recently and are increasingly being used for payments and remittances globally.

Citi sees the asset class potentially growing to $1.6 trillion by 2030 in its base case from the current $230 billion, with the caveat that regulatory support and institutional integration take hold. In the bank's more optimistic scenario, the market could balloon to $3.7 trillion, though lingering structural challenges could keep the number closer to $500 billion in the bank's bear case.

A major catalyst is the supportive regulatory stance in the U.S., with a recent presidential executive order directing the formation of a federal framework for digital assets, the report said. The clarity around stablecoin rules could allow these tokens to be more deeply embedded in the financial system, offering faster payments, improved transparency and more efficient asset settlement.

"This could lead to greater adoption of blockchain-based money and spur other use cases, financial and beyond, in the U.S. private and public sector," the authors noted.

Stablecoin issuers to become major U.S. Treasury holders

Stablecoins are expected to remain heavily dollar-denominated in the future. The report anticipates that around 90% of stablecoins in circulation in 2030 will still be tied to the U.S. dollar, cementing its dominance.

This has major implications for the global financial system. Dollar stablecoin issuers could become one of the largest buyers of U.S. Treasuries, assuming that regulations push toward backing tokens with low-risk, highly liquid traditional financial assets like government bonds. Citibank estimated issuers could hold $1.2 trillion in U.S. government debt by the end of the decade, potentially surpassing all major foreign sovereign holders.

Meanwhile, the central banks of countries in Europe and Asia will likely promote their own digital currencies, or CBDCs, the report noted.

The report pointed to several risks that could hamper the growth. Stablecoins de-pegged nearly 1,900 times in 2023 alone, including more than 600 instances involving major tokens, the report's authors wrote, citing Moody's data.

In extreme cases, mass redemptions—like those following the collapse of Silicon Valley Bank (SVB) that consequently hit USDC—can disrupt crypto liquidity, force automated selloffs and ripple through financial markets, the authors added.
