Central Bank Digital Currencies (CBDCs) have moved from being merely theoretical concepts to a stage where dozens of countries are actively testing them in various pilot schemes. Designed as a government-backed digital version of fiat money, CBDCs combine the trust of centralised monetary systems with the flexibility of digital payments. Unlike cryptocurrencies, which fluctuate based on market sentiment and are often decentralised, CBDCs are state-issued, pegged to national currencies, and intended to offer price stability and legal certainty—features that make them particularly relevant in a time of growing demand for secure digital payment systems. The main differences between CBDCs and cryptocurrencies
- Stability and trust
- Design and oversight
While cryptocurrencies like Bitcoin or Ethereum operate in highly volatile and speculative environments, CBDCs are anchored to fiat currencies and issued by central banks. This offers higher value stability and institutional backing, reducing the risk profile for users. CBDCs are programmable but centrally managed. Governments can impose compliance measures and offer consumer protection in ways decentralised crypto systems cannot. Moreover, unlike crypto assets, CBDCs are not mined or privately issued, ensuring state control over monetary supply and transaction oversight. Kar Yong Ang, financial market analyst at Octa, notes: ‘CBDCs offer a new model of digital liquidity—blending state trust and legal tender with tech efficiency. For traders, this opens doors to a more secure and transparent digital finance ecosystem.’ For underbanked populations, CBDCs also present a path toward improved financial access. The global race to develop CBDCs and the drivers behind it
- The decline of cash and rise of digital payments
- In Sweden, for example, cash transactions make up less than 10% of payments. CBDCs are seen as a public alternative to private payment apps and platforms, ensuring monetary sovereignty in the digital realm.
- Controlling private stablecoin risks
- Private stablecoins like USDT and USDC have raised concerns over systemic risk and shadow banking practices. A CBDC can serve as a stable counterbalance to these instruments, offering liquidity and legal clarity in fast-evolving financial markets.
- Financial inclusion and transparency
- CBDCs can increase financial inclusion by offering digital wallets to unbanked populations, especially in developing economies. They also offer governments more visibility into money flows, enhancing tax collection and curbing illicit finance—though this has sparked debate around surveillance and privacy.

Looking ahead: the road to adoption
CBDCs promise greater efficiency and offer more tools for governments to implement social objectives. However, they also pose new governance challenges. To thrive, states will have to balance innovation with civil liberties, infrastructure resilience, and global interoperability. As the world of digital currencies continues to develop, CBDCs are increasingly important for progressive traders to grasp. Keeping up with developments can give a vital advantage in understanding the future of money. Octa Insights: the role of a trusted intermediary
