Dollar-backed stablecoins may be quietly weakening local currencies in emerging markets, according to new research from the Bank of Korea that links buying pressure on cryptocurrency exchanges to depreciation of national money.
What the Study Found
The Bank of Korea's analysis examined trading activity involving dollar-pegged stablecoins on Binance, focusing on currency pairs that connect local money to digital assets. Researchers discovered that when buying pressure builds in these paired markets, it tends to coincide with the depreciation of the corresponding local currency.
The mechanism, according to the study, runs through the behavior of market makers. As traders in a given country move to acquire dollar-backed stablecoins, market makers must rebalance their own positions to manage risk. That rebalancing activity ripples outward into foreign exchange markets, adding downward pressure on the local currency.
When demand for dollar stablecoins rises, the local currency can quietly bear the cost.
Why It Matters for Emerging Economies
The findings highlight a growing concern among central banks that the rapid adoption of stablecoins could complicate monetary sovereignty. In economies where residents seek refuge in dollar-denominated assets, stablecoins offer an accessible on-ramp to the greenback without needing a traditional bank account or foreign exchange service.
For policymakers, that raises the prospect of a digital form of dollarization, where citizens increasingly hold their savings and transact in dollar-linked tokens rather than the national currency. Such a shift can undermine a central bank's ability to conduct independent monetary policy and manage exchange rates.
The Bank of Korea's research adds empirical weight to warnings that have circulated among regulators worldwide. Key takeaways from the study include:
- Buying pressure in Binance-paired currencies correlates with local currency weakness
- Market maker rebalancing transmits stablecoin demand into forex markets
- Emerging economies face heightened exposure to dollar-driven capital flows
As stablecoin usage continues to expand globally, the study suggests central banks may need to weigh these dynamics carefully when shaping regulation and monitoring currency stability.
