Andrew Bailey, the head of the UK’s central bank, has adjusted his previous stance on stablecoins, suggesting it would be unwise to dismiss this type of cryptocurrency outright. In an article for the Financial Times, Bailey acknowledged the potential of stablecoins to foster “innovation in payment systems.” However, he emphasized that this emerging technology must still address fundamental issues of central banking to ensure public confidence in currency, which he described as “critical” for all economies.
Understanding Stablecoins
A stablecoin represents a type of digital currency, a form of cryptocurrency managed by private entities rather than governmental financial institutions such as the Bank of England or the European Central Bank. This sector has grown substantially, fueled by what the Financial Conduct Authority characterizes as “speculative trading,” even though crypto assets currently operate without formal regulation in the UK.
Among stablecoins, Tether (USDT) is the most widely used, with other prominent examples including USD Coin (USDC-USD) and Stasis Euro (EURS-USD).

Distinguishing Stablecoins from Other Cryptocurrencies
Unlike cryptocurrencies such as Bitcoin and Ethereum, which function independently of traditional finance, stablecoins maintain a connection to stable assets, like the U.S. dollar, British pound or even the price of gold.
Their value is designed to remain relatively constant, with fluctuations occurring infrequently. Ideally, a stablecoin tied to the U.S. dollar would maintain a one-to-one value ratio. Some operate using algorithms to manage coin supply based on market dynamics, creating or removing coins in response to demand.
The UK Government’s Interest in Stablecoins
Globally, the stablecoin market is valued at approximately $200 billion (£148 billion). Given that London manages 40% of global foreign exchange transactions, the possibility of formal participation in stablecoins is appealing, as suggested by a report from Innovate Finance.
Stablecoins offer several advantages, including bypassing conventional currency exchange processes, and enabling international transactions that are “more predictable” and “lower-cost,” as reported by Yahoo Finance.
Chancellor Rachel Reeves emphasized the government’s dedication to advancing “developments in blockchain technology,” encompassing stablecoins, during her Mansion House speech in July.
Bailey stated in the FT that the BoE intends to issue a consultation paper outlining the “UK’s systemic stablecoin regime,” to ensure that the UK will “reap the benefits” associated with this new form of currency. Previously, the BoE had suggested capping stablecoin holdings at a relatively low £20,000, and proposed that no interest be offered to customers on such holdings.
Regulatory frameworks aimed at enhancing transparency have been introduced in the European Union, Hong Kong, Japan (since 2023), and the United States, which has been welcomed by members of the cryptocurrency community.
Potential Concerns Regarding Stablecoins
Even with their connection to stable assets, stablecoins can still present risks. If a stablecoin’s value deviates significantly from its target and cannot be corrected, it can experience “depegging.”
On a broader scale, a lack of regulation could pose challenges for central banks. According to Bloomberg, the collapse of a stablecoin could lead to “fire sales”—rapid selling at depressed prices due to financial difficulties—to restore market balance.
Conversely, if stablecoins “prove their worth” by facilitating large-scale exchanges and stores of value, they could erode the banks’ “monetary monopoly.”
Furthermore, as with other cryptocurrencies, an unregulated system could be vulnerable to illicit activities. The “anonymous, fast, and cheap” nature of transactions could make stablecoins appealing to criminals for scams and money laundering.
