The Bank for International Settlements has flagged a fresh concern for policymakers in developing economies: dollar-backed stablecoins may be far harder to contain within national borders than money held in traditional bank accounts, potentially undermining the tools governments use to manage cross-border capital flows.
What the Research Found
A study from the BIS concluded that stablecoins pegged to the US dollar are less responsive to capital controls than conventional bank deposits. In practice, that means the barriers governments erect to slow money moving in and out of their economies appear to have a weaker grip on stablecoin transfers.
The finding matters because capital controls are a central instrument for many emerging market authorities. They rely on these measures to defend their currencies, stabilize financial systems, and prevent destabilizing surges of money crossing their borders during periods of stress.
When money can slip across borders with a few taps, the walls governments build around their economies start to look a lot thinner.
Why It Threatens Monetary Sovereignty
Stablecoins are digital tokens designed to hold a steady value by tracking a reference asset, most commonly the dollar. Because they move over blockchain networks rather than through the regulated banking system, they can bypass some of the choke points that authorities traditionally use to monitor and restrict capital.
For emerging markets, where residents may seek dollar exposure to hedge against inflation or currency depreciation, that ease of movement carries real consequences. Widespread adoption could accelerate a shift away from local currencies, complicating central banks' efforts to steer domestic monetary policy.
The BIS researchers frame this as a growing challenge to monetary sovereignty — the ability of a nation to maintain independent control over its own money and financial conditions.
The Broader Policy Debate
The study lands amid intensifying global scrutiny of stablecoins as their usage expands. Regulators worldwide are weighing how to accommodate the technology's benefits while guarding against risks to financial stability and policy autonomy.
Key considerations emerging from the discussion include:
- The tension between financial innovation and a state's control over cross-border money flows
- The risk of accelerated dollarization in economies with weak or volatile local currencies
- The difficulty of applying existing capital-control frameworks to blockchain-based assets
The BIS, often described as the central bank for central banks, has repeatedly urged caution on crypto assets. Its latest analysis adds a specific dimension to
