Bank of Korea Study Links Dollar Stablecoins to Local Currency Depreciation
Researchers at the Bank of Korea found that increased trading volume in dollar-backed stablecoins correlates with depreciation in local currencies, particularly through market maker activity on platforms like Binance. The study suggests stablecoin demand can transmit pressure into foreign exchange markets.

How Stablecoins Affect Local Currencies
Researchers at the Bank of Korea identified a direct mechanism by which dollar-backed stablecoins can weaken local currencies. When trading volume in stablecoin pairs against local currencies rises—particularly on exchanges like Binance—market makers rebalance their positions by selling local currency to maintain inventory, creating downward pressure on those currencies' exchange rates.
The effect appears concentrated in the foreign exchange market's interaction with crypto trading. Rather than stablecoin purchases directly replacing local currency demand, the mechanism works through the secondary effect of how market makers absorb and hedge their exposure across both crypto and traditional FX venues.
Implications for Emerging Markets
The study's findings carry particular relevance for emerging-market countries where retail cryptocurrency adoption and stablecoin trading volumes are significant. If stablecoin trading can transmit crypto demand into FX markets and suppress local currency valuations, central banks may need to account for this channel when modeling capital flows and setting monetary policy.
The Bank of Korea's analysis suggests the effect is measurable and consistent, though the research did not quantify the magnitude of currency depreciation per unit of stablecoin trading volume or specify which local currency pairs showed the strongest correlation.
Why It Matters
For Traders
Stablecoin pairs against emerging-market currencies may exhibit correlation with FX moves; arbitrage opportunities may exist if local currency weakness is predictable from on-chain volume.
For Investors
Central banks monitoring stablecoin flows as a driver of capital flows and currency pressure could shape future regulatory treatment of offshore dollar-backed tokens.
For Builders
Stablecoin issuers and DEXs operating in emerging markets should anticipate increased scrutiny from regulators concerned about unintended FX transmission channels.
