According to Danmarks Nationalbank's latest assessment, rapid global growth in U.S. dollar-pegged stablecoins could expose Denmark to indirect financial market volatility and liquidity risks, while assigning a 0% immediate threat to domestic financial stability. The central bank's warning distinguishes between direct exposure—which Denmark currently faces at negligible levels—and second-order effects transmitted through global markets, cross-border payment corridors, and the behavior of internationally active financial institutions. The warning reflects a broader shift among European central banks and supervisors, which have moved from treating stablecoins as a niche crypto-market phenomenon to evaluating them as potential amplifiers of systemic stress. Denmark's position is notable because the country's own financial system has limited direct integration with dollar-denominated stablecoin issuers, with the central bank's concern centered on a disorderly event in the global stablecoin market could propagate through channels Denmark does not control. As per Bank of England policymaker Carolyn Wilkins, dollar stablecoins already have a considerable first-mover advantage, with about 98% of stablecoin value denominated in dollars.
As reported by Danmarks Nationalbank, stablecoin adoption could affect Denmark through three distinct channels: payments infrastructure, overall financial stability, and monetary policy transmission. The central bank's decision to group these risks together signals it views stablecoins as a potential substitute for both commercial bank deposits and traditional payment rails, rather than merely a speculative asset class. The monetary policy transmission mechanism describes how changes in the central bank's policy rate flow through to lending rates, deposit rates, and ultimately to spending and investment decisions across the economy. Danmarks Nationalbank's concern is that stablecoins could short-circuit this chain when households and businesses hold meaningful shares of their liquid assets in stablecoins rather than bank deposits, as stablecoin-pegged tokens typically pay no interest tied to Danish policy rates. According to Bank of England analysis, stablecoins could move deeper into payments and international finance, with cross-border settlement systems potentially lowering costs in payment corridors where banking services remain slow or expensive.
The Bank of England has identified a critical feedback mechanism where stablecoin issuers' Treasury bill holdings create additional demand for US government securities during growth periods, while large redemptions could reverse this demand and create selling pressure during market stress. USDT issuer Tether and USDC issuer Circle held almost $150 billion in Treasury bills at the end of 2025, with their net purchases reaching about $33 billion during the year. As per Bank of England research, stablecoin inflows can place modest downward pressure on short-term Treasury yields as issuers buy more safe assets, though the combined position remains small compared with the full Treasury market. The same reserve structure that sends money into Treasury bills during stablecoin growth can create selling pressure when users redeem tokens, as stablecoins are claims holders expect to exchange for cash at face value, potentially forcing issuers to raise cash quickly even outside conventional market hours. Tether generated about $1.5 billion in operating profit during Q2 2026, supported by returns from its Treasury and repo holdings, while Circle's reserve portfolio returned 3.8% with average USDC circulation doubling from $38.1 billion to $76.2 billion in Q4 2025.
According to Danmarks Nationalbank's analysis, stablecoin services become easier to access across Europe through banks, fintech companies, and regulated payment infrastructure. Recent studies show cryptocurrency ownership in Denmark stood at 4% in 2025, slightly lower than the previous estimate of 6% in 2024, and much lower than Norway's 11% ownership rate. Stablecoins in circulation reached roughly $300 billion by mid-2026, compared with less than $5 billion at the beginning of 2020, though most activity still involves crypto trading, lending, collateral, and market liquidity. Denmark operates within the European Union's Markets in Crypto-Assets regulation (MiCA), which establishes a comprehensive framework for crypto asset issuers and service providers across the bloc. The Danish Financial Supervisory Authority (Finanstilsynet) serves as the national competent authority for MiCA implementation in Denmark, with MiCA's stablecoin provisions requiring issuers to hold sufficient reserves and obtain authorization from competent authorities. The stablecoin market has grown substantially across the euro area through 2025 and into 2026, though Denmark-specific adoption data remains limited.
The timing of the warnings is significant, as with MiCA now in force across the EU, stablecoin issuers seeking to serve Danish users must comply with reserve requirements, redemption obligations, and operational standards. Danmarks Nationalbank's statement suggests that even compliant stablecoins pose structural questions for monetary policy that prudential regulation alone cannot answer. The central bank retains substantial capacity to respond, including issuing guidance to Danish banks about stablecoin exposure, coordinating with the FSA on payment system oversight, or recommending legislative measures if adoption accelerates. The Bank of England's framework for systemic sterling stablecoins applies stricter reserve and liquidity requirements than the US GENIUS Act, with the UK model including payment-system access, liquidity contingency plans, and procedures for issuer failure. The next concrete signal to watch is whether Danmarks Nationalbank publishes a fuller analysis with specific stablecoin issuers, reserve data, and quantitative transmission estimates, which would indicate the central bank has moved from flagging a risk to actively modeling its propagation. The stablecoin sector is not yet large enough to pose a major threat to the Treasury market or create a material financial-stability risk in the UK, according to Bank of England analysis, though a large depegging event could still damage confidence in regulated tokens.
