Banque de France Set Wholesale CBDC Experiments in Motion

The Banque de France used a December 4, 2019 speech to move a central-bank digital currency from policy debate toward an experimental program. Governor François Villeroy de Galhau said the bank wanted to begin experiments rapidly and would issue a call for projects before the end of the first quarter of 2020, with particular interest in integrating a wholesale CBDC into the exchange and settlement of tokenized financial assets.

That was a commitment to test, not a decision to issue a digital euro. No live currency, technical design, partner list or launch date was announced on December 4, 2019. The distinction mattered because contemporaneous summaries sometimes compressed a project call into the broader claim that France would “test a digital euro” in early 2020.

A central-bank response to private money

Villeroy delivered the announcement at a conference of France’s Autorité de contrôle prudentiel et de résolution, which supervises banks and insurers. He framed the initiative against two shifts: payments moving toward non-bank and Big Tech providers, and a new generation of stablecoins promising faster cross-border transfers while raising compliance, financial-stability and monetary-sovereignty concerns.

Facebook’s proposed Libra project was the immediate institutional backdrop. Villeroy noted that France’s Group of Seven presidency had asked Benoît Cœuré to examine global stablecoins after Libra’s June 2019 announcement, and that the resulting report had been published in October 2019. The French central bank’s answer was therefore two-track: coordinate regulation of private stablecoins while testing whether public money could operate in new digital-market infrastructure.

This was not an endorsement of bitcoin or privately issued crypto-assets. In the same speech, Villeroy characterized bitcoin as highly volatile and distinguished speculative crypto-assets from asset-backed stablecoins and from a liability issued by a central bank.

Why wholesale came first

The proposed experiment focused on wholesale use between financial institutions, not a wallet for the public. Banks already accessed central-bank money electronically through reserve accounts. The research question was whether a tokenized form of that money could fit into new procedures for trading and settling tokenized securities, potentially lowering intermediation costs and improving post-trade resilience.

Villeroy set out three possible objectives for CBDC work: preserving public access to central-bank money where cash use was falling; capturing efficiencies in settlement and post-trade activity; and reinforcing monetary sovereignty against private systems such as Libra. He also separated a possible wholesale design, which could use blockchain and smart contracts, from a simpler retail version for everyday payments.

The speech left the hard questions open. Villeroy identified risks to bank liquidity, profitability and intermediation if deposits moved suddenly into central-bank money. For a retail form, legal-tender status, account-versus-token design, non-resident access and anonymity limits were unresolved. He said the Banque de France’s work would feed into the Eurosystem’s consideration of an “e-euro,” rather than presenting the French program as a finished euro-area policy.

What the event established

For digital-asset markets, the December 4 development was an institutional signal, not a price catalyst that can be measured from the surviving records used here. A major euro-area central bank had committed staff, a reorganized payments directorate and a near-term project process to tokenized settlement. It put public digital money and private stablecoins inside the same strategic debate over who would provide trusted settlement infrastructure.

Later context

The Banque de France reported in November 2021 that the first phase of its wholesale CBDC program launched in March 2020. It said nine experiments were selected from nearly 40 proposals and conducted from September 2020 with private firms, other central banks and public authorities. Those later results confirm that the December 2019 commitment produced an experimental program; they do not change what had been announced on December 4, 2019.
