Core Focus: The three main structural drivers behind global CBDC interest: the decline of physical cash, the rapid proliferation of privately issued stablecoins, and the persistent inefficiency of cross-border payment systems.

In-Depth Notes:
CBDC interest is not a speculative development but a response to powerful structural forces reshaping the monetary and financial landscape. These drivers are fundamentally challenging the traditional role of central bank money and the stability of the international monetary system .

The Decline of Physical Cash and the Erosion of Public Money:
The decline of physical cash is the most immediate driver of CBDC exploration. In many economies, cash usage is declining, which risks leaving central bank money increasingly absent from everyday retail payments . This absence creates a vulnerability: central bank money is the ultimate monetary anchor, providing the public trust and stability on which the entire financial system depends. As cash becomes less relevant to daily transactions, that anchor weakens. A CBDC is seen as the digital complement to cash, ensuring that central bank money remains accessible to the public and that the central bank retains a visible presence in the payment system. The European Central Bank views the absence of a Europe-wide digital payment solution as a vulnerability, exposing European payment infrastructure to external risks .

The Proliferation of Stablecoins and the Privatization of Money:
Privately issued digital money, particularly stablecoins, is growing rapidly. Stablecoin market capitalisation is approaching $300 billion, and they are increasingly used for both crypto trading and payment applications . Stablecoins are largely operating outside the traditional banking system, without deposit insurance, central bank oversight, or full reserve transparency . This represents a “privatization” of money, where private entities could effectively control the means of payment. For monetary authorities outside the United States, the use of US dollar-pegged stablecoins creates a particular concern: fluctuations in the US dollar’s value could undermine the effectiveness of their domestic monetary policy . A CBDC is a strategic response to this challenge, providing a secure, public, and risk-free digital alternative to private money that would help central banks reaffirm their monetary sovereignty .

The Inefficiency of Cross-Border Payments:
Cross-border payment systems remain persistently inefficient. They are slow, costly, opaque, and inaccessible for many users. CBDCs, particularly wholesale CBDCs and multi-CBDC arrangements (mCBDCs), offer a pathway to address these inefficiencies by enabling faster, cheaper, and more transparent cross-border transactions . CBDCs could allow for direct central bank-to-central bank settlements across borders, potentially streamlining the correspondent banking chain . The BIS has brought together central banks from multiple countries to test interoperable multi-CBDC arrangements, and wholesale CBDCs are increasingly seen as a foundation for tokenisation of deposits and assets more broadly . This structural driver has geo-economic implications, as CBDCs could facilitate international transactions that no longer rely on the use of the US dollar and therefore on clearing institutions under US jurisdiction .
