Banks Eye Stablecoins: Trillions in Digital Asset Volume Forecast by 2030

The financial world has moved past the debate of whether stablecoins belong in finance, now actively focusing on how these digital assets will integrate into the broader financial system. Globally, financial institutions are making concerted efforts to offer secure and regulated infrastructures for stablecoins, driven by projections that digital asset volumes will reach trillions of dollars by 2030. This transformation has the potential to reshape the traditional banking model.

At the core of this shift is the rapid expansion of the stablecoin market. Stablecoin issuance reached approximately $280 billion by September 2025, up from $200 billion at the start of the year. According to Citi reports, stablecoin issuance is projected to hit $1.9 trillion in a base case scenario and $4.0 trillion in a bull case scenario by 2030. This growth is fueled by the crypto-native ecosystem, the rise of e-commerce and digitally native companies, and increasing international demand for holding USD. Regulatory developments, such as the GENIUS Act passed in the U.S., which establishes a federal framework for stablecoins, are also accelerating this integration process.

Banks are pursuing various strategic paths in this new era. Some institutions are considering issuing their own stablecoins, while others are exploring partnerships with existing regulated issuers or integrating established networks into their operations. These approaches enable banks to digitize traditional business areas such as liquidity management, cross-border payments, and treasury services. For instance, digital dollars like Circle's USDC can serve as near-instant settlement tools, reducing prefunding needs and delays. Consumers are also receptive to this change; research indicates that approximately 75% of consumers would be willing to try stablecoins if offered by their bank.

The proliferation of stablecoins presents both opportunities and challenges for the banking sector. On one hand, they offer potential new revenue streams through transaction fees, custody services, asset tokenization, and decentralized finance (DeFi) integration. On the other hand, stablecoins compete directly with traditional bank payment services by offering low-cost, instant, 24/7 payment capabilities, posing a risk of deposit displacement. However, experts suggest that this does not imply the complete disintermediation of banks, but rather points to a future where stablecoins, tokenized deposits, and central bank digital currencies (CBDCs) coexist.

In the broader economic and political context, stablecoin regulation has become a global priority. The GENIUS Act in the U.S. contributes to the global adoption of core regulatory principles such as 1:1 reserve backing, high-quality liquid assets (HQLA), and prohibitions on interest payments. These regulations aim to foster innovation while safeguarding financial stability. Furthermore, the growth of USD-pegged stablecoins is also seen as a mechanism to maintain the global dominance of the dollar in the digital finance landscape. The role of banks in this new order will depend on their ability to compete and collaborate within a fragmented payment ecosystem.

Analysts and market experts anticipate that stablecoins will become a fundamental infrastructure layer of the financial system in the coming period. According to Citi's projections, with a 50x transaction velocity assumption, stablecoins could support nearly $100 trillion in annual transaction activity by 2030 in the base case, and up to $200 trillion in the bull case. This growth will also increase demand for U.S. Treasury securities, which stablecoin issuers hold as collateral. It is crucial for banks to define their participation models early to create sustainable value in this emerging ecosystem. The future promises a faster and smarter financial system where stablecoins, bank tokens, and CBDCs operate in concert.
