The Future of Money: How Stablecoins, CBDCs and Digital Banking Are Redefining the Financial System
Money is quietly changing form. It is moving from paper and metal into entirely digital representations that travel at the speed of the internet. Yet what appears as a simple balance on a screen can mean very different things depending on who issues it, who guarantees it, and how it functions. Today, three systems define the landscape of digital money: traditional digital banking, stablecoins, and central bank digital currencies (CBDCs). Each has distinct characteristics, technologies, and implications for the future of finance.
Digital Banking: The Money We Already Use
When a person checks their bank account, the numbers they see are digital banking money - an entry in the database of a commercial bank. This money is the bank’s promise to pay. It functions smoothly because banks are regulated and supervised, and because deposit insurance provides a safety net. However, this money ultimately depends on the financial health of private institutions. If a bank fails, deposits are insured only up to a certain limit. Digital banking money is therefore a claim on a bank, not on the state.
Digital banking dominates everyday transactions - salaries, utility payments, credit cards and transfers. It is efficient and trusted but not instantaneous across borders, as transfers rely on layers of intermediaries through systems like SWIFT or SEPA.
Stablecoins: Private Digital Money with Public Ambitions
Stablecoins are digital tokens designed to maintain a stable value, often pegged to a traditional currency such as the US dollar or the euro. Issued by private companies, stablecoins are backed by reserves - typically cash and short-term government securities - held to mirror the value of the tokens in circulation. The goal is stability, making stablecoins usable for payments, remittances and trading.
Well-known examples include Tether (USDT), USD Coin (USDC), and euro-based versions such as Tether Euro (EURT) and Circle’s Euro Coin (EUROC). These coins operate on public blockchains such as Ethereum, enabling instant global transfers without relying on banking hours or geographical limits.
The stablecoin sector has grown rapidly. Global stablecoin transaction volume rose from about 3.5 trillion US dollars in 2023 to over 5.5 trillion in 2024. Market capitalisation stood near 230 billion dollars in early 2025 and is projected to reach two trillion dollars by 2028. Stablecoins are now a key element in crypto markets and cross-border finance, but their reliance on private issuers raises questions about transparency, auditing, and regulatory oversight.
The European Union’s Markets in Crypto-Assets (MiCA) regulation, coming into effect in 2025-2026, introduces strict requirements on reserve management and supervision. Alongside, major European financial institutions are developing euro-denominated stablecoins under regulatory frameworks. DWS, a leading German asset manager, has announced a regulated euro stablecoin to launch in 2025, and a consortium of European banks is working on G7 currency-pegged stablecoins, including a euro version.
Central Bank Digital Currencies (CBDC): The Public’s Digital Cash
A central bank digital currency, or CBDC, is a digital form of state-issued money - a direct liability of the central bank. It is the digital equivalent of cash: fully guaranteed, universally accepted, and risk-free. When someone holds CBDC, they hold money issued by the state itself rather than a promise from a commercial bank.
The motivation for CBDCs is not to imitate cryptocurrencies but to modernise official money for a digital world. They ensure that public money remains relevant in an economy increasingly dominated by private payment systems and global technology firms. CBDCs could make domestic and international payments faster and cheaper, provide resilience if commercial systems fail, and allow governments to distribute support or benefits directly to citizens.
The Chinese digital yuan (e-CNY) is currently the largest pilot, with over 7 trillion yuan - nearly 1 trillion US dollars - transacted in test regions. India is developing the digital rupee for both retail and wholesale use. The European Central Bank is preparing the digital euro, now in its design phase, with pilot issuance expected around 2027–2028. To prevent disruption to the banking system, the ECB plans to limit how much CBDC each person can hold and use a “waterfall mechanism” to move excess funds back into bank deposits automatically.
Most CBDCs do not rely on public blockchains. Instead, they use permissioned distributed ledger technology or secure centralised systems operated by the central bank and approved financial institutions. This approach combines the traceability and speed of blockchain with the control and compliance required for monetary policy.
Why Three Systems?
At first glance, CBDCs, stablecoins and digital banking money seem similar: all are digital, and all show as numbers on a screen. But the difference lies in who stands behind the promise.
With bank deposits, the promise comes from a commercial bank. With stablecoins, it comes from a private issuer managing reserves. With a CBDC, the promise comes directly from the central bank and by extension from the state. The first carries some credit risk, the second depends on private audits, and the third is as secure as the sovereign itself.
Each system also serves different goals. Stablecoins promote innovation and global connectivity. CBDCs safeguard public trust and monetary sovereignty. Digital banking remains central to lending, investment, and financial intermediation. Their coexistence represents not competition but an evolution of money into distinct but connected layers.

The Future Landscape
As digital money matures, users will have multiple choices. Bank accounts will remain the core of credit and finance. Stablecoins will continue to dominate blockchain ecosystems and fast international payments. CBDCs will ensure access to secure, state-issued money for everyone in a digital economy. The interaction among these systems will shape how individuals, businesses, and governments use and think about money.
The distinction between them may seem technical, yet it reflects one of the most significant changes in financial history: the redefinition of what counts as “money” itself. Whether issued by a bank, a private company, or the central bank, the key question for users will increasingly be not how digital their money is, but who stands behind it.
