Followingstablecoins: A double-edged sword in restricted currency economies
The International Monetary Fund (IMF) has released a new working paper reminding governments of the possible impact of stablecoins pegged to the U.S. dollar in countries with strict currency controls. While these cryptocurrencies can provide much-needed access to foreign currency, they also pose significant risks, including possible rapid capital outflows during periods of financial turmoil.
stablecoins and exchange rate dynamics
IMF economist Brandon Joel Tan introduced a model to explore the interaction between stablecoins and restricted foreign exchange markets, demonstrating their role as an important source of currency substitution with limited official channels. Since official exchange rates often deviate from actual market demand, stablecoins can reflect real demand for the U.S. dollar and may indicate a currency shortage. Visibility of the market value of stablecoins can serve as a thermometer of the scarcity of the dollar, triggering massive withdrawals from the local currency in times of economic trouble. Tan suggested that regulators may need to temporarily restrict large-scale stablecoin trading to prevent disruptive currency runs. Stable coins have attracted attention because they "make dollar-like rights more accessible." Their market prices provide visible evidence of demand for the dollar, especially when official exchange rates deviate significantly from market reality, which can lead to mass escapes from the local currency. Faced with market pressure, regulators should consider strategic intervention in stablecoin transactions to curb runaway capital outflows and stabilize the national economy during crises.
Practical application cases
In places such as Latin America, stablecoins have been used under strict capital controls. For example, in Bolivia, airport retailers have used the value of the USDT as a pricing benchmark, although transactions are still conducted in recognized currencies such as the U.S. dollar or Boliviano. Similarly, in Argentina, stablecoins provide hedging tools against inflation and currency constraints, and exchange of local currencies into dollar-pegged tokens through the "cryptocurrency cave" provides a useful alternative.
Regulatory concerns and risks
Global regulators are cautious about the widespread use of stablecoins. The Financial Stability Board (FSB) highlighted potential risks, including the risk of increasing currency substitution and undermining standard monetary policy. Stable currencies may contribute to the circumvention of capital controls, posing a systemic threat to countries in difficult economic situations. The FSB warned global leaders to closely monitor the growing influence of stablecoins as these digital assets become increasingly linked to local and global financial networks. To mitigate these risks, regulators are expected to strengthen oversight and develop comprehensive policies to manage the growing influence of stablecoins, especially in countries with fixed or strictly controlled exchange rates.
stablecoins are both an important tool to circumvent monetary restrictions and a major threat to economic stability. As demand for these digital assets grows, a balanced regulatory approach will be crucial for countries facing limited access to money in the broader context of global financial integration.
