Cryptocurrencies

The Bank for International Settlements has warned that diverging national approaches to stablecoin regulation could create openings for regulatory arbitrage as stablecoins become more closely linked to the traditional financial system.

In a recent bulletin, the BIS says the growth of stablecoins is creating policy challenges ranging from anti-money laundering and financial integrity to broader risks to financial stability. It argues that inconsistent regulatory treatment across jurisdictions could allow firms to exploit gaps between rulebooks, making supervision less effective and fragmenting cross-border financial activity.

The BIS also points to broader systemic concerns as stablecoins move closer to mainstream finance. Their expanding role could reshape how funds move through the financial system, with implications for bank funding, credit intermediation, and the transmission of stress during market volatility. Separate BIS research has also found that stablecoins are playing a growing role in safe asset markets, with implications for financial stability and monetary policy transmission.

One key concern is how stablecoin structures could behave under pressure. If large numbers of users redeem at once, issuers may need to liquidate reserve assets quickly, potentially transmitting stress into underlying markets.

The BIS bulletin frames these risks as part of a broader challenge: stablecoins are no longer crypto instruments operating in isolation, but are increasingly linked to core parts of the financial system.

The BIS also warns that regulation is made harder by the fact that many stablecoins circulate on public blockchains. In that environment, conventional controls such as anti-money laundering checks and identity verification are often weakest at the points where users move between crypto markets and traditional finance.

That is why the bulletin stresses the importance of stronger controls at entry and exit points, rather than relying only on rules aimed at issuers themselves.

For some jurisdictions, the concerns go beyond prudential supervision. The BIS says the wider use of foreign-currency-denominated stablecoins could raise concerns about monetary sovereignty and weaken existing foreign exchange controls. That risk is especially relevant in countries where domestic monetary and exchange rate frameworks are more exposed to external pressures.

The broader significance of the warning is that the BIS is pushing for more coordinated and tailored regulation at a moment when stablecoins are moving closer to mainstream use.

Its message is not that all stablecoins should be regulated identically, but that fragmented oversight could undermine policy effectiveness, increase systemic vulnerabilities, and make cross-border risks harder to contain.
