Denmark central bank flags risks from dollar stablecoins

Danmarks Nationalbank warned that US dollar stablecoins could create risks for financial stability, payment systems and monetary policy by channeling large amounts of private-sector dollar liquidity into the economy and exposing users and banks to sudden losses or runs.

In a recent assessment, the central bank described stablecoins as cryptocurrency tokens that aim to keep a fixed value against the U.S. dollar and said many are issued by private firms that rely on pools of assets held off balance sheet.

The bank raised concerns about the composition and transparency of the reserves backing stablecoins, unclear legal rights of holders, operational weaknesses and the potential for rapid outflows that could spill over into the mainstream financial system.

Nationalbanken explained that if reserve asset pools are invested in short-term commercial paper or held in deposit accounts at banks, large redemptions could force asset sales or create liquidity stress at intermediary banks. For a small, open economy like Denmark, the bank said these dynamics could weaken control over domestic liquidity and increase direct transmission of U.S. monetary policy through privately issued instruments.

The assessment highlighted cross-border implications, noting that stablecoins can be used across jurisdictions and that regulatory gaps in one country can create vulnerabilities elsewhere. Nationalbanken recommended closer cooperation at European and international levels, clearer settlement and custody arrangements, and stronger transparency so regulators and market participants can assess reserve quality and redemption risks.

The central bank identified operational and legal risks that could interrupt payments, including smart-contract failures, concentrated custody arrangements and unclear bankruptcy rules for issuers. It warned that payment disruptions would affect not only crypto users but also firms and service providers that use stablecoins for settlement or cross-border transfers.

On consumer protection and anti-money-laundering fronts, Nationalbanken said the ease with which stablecoins move value across borders raises tracing and customer due-diligence challenges. The bank urged clearer rules for identifying customers and tracing transactions to reduce illicit finance risks if stablecoin use grows.

As policy responses, the assessment called for stronger public disclosure requirements for issuers on reserve composition and redemption mechanisms, prudential rules for firms offering stablecoin-backed accounts or custody services, and limits on how stablecoins are integrated into traditional banking services unless supervisory safeguards are in place. The bank also suggested policymakers consider treating some stablecoin activities like deposits or money-market funds for regulatory purposes.

Nationalbanken underlined the dependence of dollar stablecoins on the U.S. dollar’s global role. The assessment said that if private dollar-denominated tokens become a substitute for bank deposits or other short-term money instruments, monetary authorities may face challenges in ensuring price stability and in implementing domestic monetary policy tools.

The central bank concluded that the speed and form of regulation will determine whether stablecoins can provide useful payment services without creating new systemic risks and called for timely, coordinated action to keep financial and payment systems stable as digital assets grow.
