What are CBDCs and how do they threaten private money?

The short answer

A central bank digital currency is digital money issued directly by a central bank, with the same legal status as banknotes but in electronic form. Unlike a commercial bank deposit, which is a claim on a private bank, a CBDC is a claim on the central bank itself. Unlike a stablecoin, it is sovereign rather than private. Two main forms exist: retail CBDCs (for households and businesses) and wholesale CBDCs (for inter-institution settlement).

The popular framing pits CBDCs against private stablecoins. The data tells a more nuanced story. CBDCs would compete primarily with bank deposits, since both fill the same household demand for safe, digital, settlement-ready money. Stablecoins serve a different niche — programmable, 24/7, blockchain-native dollars used heavily in crypto trading and cross-border flows.

The US has taken the unusual step of banning a retail digital dollar. The eurozone, China, and most major economies are moving in the opposite direction. The geopolitical implications are at least as important as the technical ones.

What the data shows

The CBDC landscape in 2026 is uneven (Atlantic Council CBDC Tracker, IMF, BIS):

• Countries exploring CBDCs: 137, representing roughly 98% of global GDP (up from 35 in May 2020)
• Countries in advanced exploration phase: 72 (development, pilot, or launch)
• Active pilot projects: 49 globally
• Retail CBDC launches: Bahamas (Sand Dollar, October 2020), Nigeria (eNaira, October 2021), Jamaica
• China’s e-CNY: cumulative transactions of 16.7 trillion yuan (about $2.37 trillion) by end of November 2025; reclassified from M0 to M1 (interest-bearing) in January 2026
• Cross-border wholesale CBDC projects: 13 active, including mBridge (China, Thailand, UAE, Hong Kong, Saudi Arabia)
• US position: executive order in 2025 prohibits retail CBDC development

The pace and direction differ markedly across regions: emerging markets pursue retail CBDCs primarily for financial inclusion, while advanced economies focus more on wholesale settlement and cross-border applications.

Why it happens — the macro mechanism

Three structural channels explain how CBDCs interact with the existing monetary system.

The disintermediation channel targets banks, not stablecoins. If retail savers can hold central bank money directly, they may shift balances out of commercial bank deposits during stress events, accelerating bank runs. This is the central concern that the ECB, the Bank of England, and the Fed have flagged repeatedly. By contrast, stablecoins serve a niche (24/7 programmable dollars on blockchain rails) that retail CBDCs would typically not match. This is the angle most overlooked: the CBDC threat is to commercial banks first, to private stablecoins only second. Read more on bank-run dynamics.

The geopolitical channel reshapes cross-border payments. Wholesale CBDC projects like mBridge enable cross-border settlement that bypasses the dollar-denominated correspondent banking network. The BIS’s withdrawal from mBridge management in 2024 signaled how politically sensitive this layer has become. China’s e-CNY upgrade to interest-bearing status in January 2026 strengthens the digital yuan as a competitor to dollar-based settlement. See how the dollar maintains reserve status.

The privacy and surveillance channel. CBDCs create a digital trail that physical cash does not. The same feature that enables policy transmission (programmable spending, targeted stimulus) also creates surveillance capacity. The political acceptability of CBDCs varies sharply by country based on this tradeoff — and the US executive order banning a retail digital dollar reflects an unusually strong political resistance to that surveillance dimension.

Synthesis by regime: in pre-2020 monetary architecture, central bank money to the public existed only as physical cash, and electronic balances at the central bank were available only to commercial banks and select institutions. In the 2020-2024 exploration regime, retail CBDCs moved from theory to small-scale launches in three jurisdictions, and 49 pilots emerged. In the post-2025 regime, the landscape diverges sharply: the US bans retail CBDCs while China, Europe, and emerging markets accelerate. The transition parameter is political acceptability of central bank surveillance trading against monetary modernization, with very different national answers.

The CBDC question is not whether central banks can build digital money, but whether the public wants central bank money it can be programmed with. The answer varies by country.

What it means for different economic actors

Bank depositors. A retail CBDC introduces a third option alongside cash and bank deposits. In stress events, retail savers may shift balances toward central bank money rapidly, putting pressure on bank funding. Most CBDC proposals include holding limits and tiered remuneration to mitigate this disintermediation risk, but the design tradeoffs are not fully resolved.

Commercial banks. The structural risk is loss of cheap deposit funding if retail CBDCs become widely held. Wholesale CBDCs are more bank-friendly because they modernize the existing inter-institution settlement layer. The bank lobby’s split positioning — supportive of wholesale, skeptical of retail — reflects this asymmetry.

Stablecoin issuers. The competitive threat is real but uneven. A retail CBDC in the eurozone could substitute for euro-denominated stablecoins in everyday payments, but USDT and USDC dominance in crypto trading would likely persist. The US ban on a retail digital dollar effectively cedes the dollar-stablecoin niche to private issuers.

A common error is to treat all CBDCs as equivalent. The macro and political implications differ sharply between retail and wholesale designs, between advanced and emerging-market launches, and between democracies with strong privacy norms and authoritarian systems where surveillance is a feature rather than a concern.

Frequently asked questions

Why has the US banned a retail digital dollar while others embrace CBDCs?

The 2025 US executive order reflects a coalition of concerns: financial privacy advocates worried about surveillance, banks concerned about disintermediation, and political opposition to expanding central bank reach over individual transactions. The ban does not affect wholesale research — the US remains active in Project Agorá, a multilateral wholesale CBDC initiative. The split position effectively reserves cross-border settlement modernization while preventing retail surveillance capacity.

How would a digital euro affect ordinary households?

The ECB’s digital euro design as of 2026 includes household holding limits (typically discussed in the range of a few thousand euros per person) to prevent large-scale disintermediation of bank deposits. Daily payments would work much like existing electronic transfers, with the key differences being settlement on central bank infrastructure and offline capability for small transactions. The privacy framework remains a significant point of debate within the ECB project.

Could China’s digital yuan threaten dollar dominance?

The threat operates through cross-border wholesale channels rather than retail substitution. Project mBridge and bilateral CBDC swaps create alternatives to dollar-denominated correspondent banking for sanctioned or sanctions-vulnerable economies. The scale remains small relative to the dollar system, but the trajectory is meaningful. The January 2026 reclassification of e-CNY to M1 (interest-bearing) status increases its appeal for cross-border use.
