Dollar-backed stablecoins may help households and firms obtain foreign currency when official channels are constrained, but the same instruments could intensify pressure on domestic currencies in a crisis, according to a working paper from the International Monetary Fund.
The paper examines economies with fixed or heavily managed exchange rates, where access to US dollars through banks or official markets can be limited. In that setting, it says, stablecoins can serve as an additional route to foreign currency and may become an important reference point for pricing outside the formal system.
Stablecoins as a parallel FX channel
The IMF paper models how stablecoins affect parallel foreign-exchange markets when official dollar access is rationed. Its central finding is that dollar stablecoins can improve access to dollars when demand cannot be fully met through banks or other approved channels.
According to the paper, this role is especially relevant in places where the official exchange-rate regime is tightly controlled and shortages in formal FX markets push users toward alternative mechanisms. In such environments, stablecoins may function not only as a payment tool but also as a practical substitute for access to foreign currency.
A new benchmark outside official markets
The paper also argues that stablecoins are already being used in countries where official dollar access is restricted. As their use spreads, their prices can act as a parallel benchmark for foreign exchange, offering a widely observed signal of demand for dollars outside the official market.
That price signal may make informal FX conditions more visible in real time. But the IMF paper suggests this visibility cuts both ways: while it can improve access and price discovery, it can also concentrate market attention on a single indicator during periods of stress.
Risk of faster exits in a currency crisis
The paper warns that the same stablecoin price signal that helps users access dollars in normal shortages could amplify exits from the local currency when pressure becomes severe. In a crisis scenario, a stablecoin watched across the market could encourage many users to move out of the domestic currency at once.
Rather than describing stablecoins as a one-sided threat, the paper presents them as a tool that changes how pressure emerges in parallel FX markets. It says the convenience and visibility of stablecoin markets may accelerate shifts that might otherwise unfold more gradually.
Policy concerns and possible limits
The article notes that regulators have already raised broader concerns around stablecoin use in such economies. Those risks include greater exposure to currency substitution, weaker transmission of monetary policy, and the circumvention of capital-flow measures. Authorities have also stressed the importance of assessing liquidity and operational risks as stablecoins become more connected to the wider financial system.
Against that backdrop, the IMF working paper suggests regulators may need temporary restrictions on unusually large transactions or transfers driven by panic during acute periods of market pressure. The paper frames that as a possible response to destabilizing surges rather than a general rule for normal market conditions.
The broader implication is that dollar stablecoins may ease a real access problem in tightly managed currency systems while also creating a faster transmission channel for stress. The IMF paper presents both effects as relevant for policymakers weighing how stablecoins interact with official FX controls and parallel markets.
