Dollar Stablecoins Depress Local Currencies, Bank of Korea Study

A study conducted by the Bank of Korea has found that dollar-backed stablecoins can exert downward pressure on local currencies, a phenomenon particularly evident when these stablecoins are paired with the Binance exchange. The research indicates that increased buying pressure in Binance-paired currencies correlates with the depreciation of local currencies. This occurs as market makers adjust their positions to maintain equilibrium, effectively reducing the value of the local currency against the dollar-backed stablecoin. The study highlights a mechanism where the demand for stablecoins, often used as a bridge to access global markets or for speculative trading, can lead to a reallocation of capital away from local currency assets. This dynamic is exacerbated by the significant trading volumes and liquidity available on platforms like Binance, which facilitate rapid and large-scale transactions involving stablecoins.

The Bank of Korea's analysis suggests that the arbitrage activities undertaken by market makers play a crucial role in this process. When demand for a stablecoin like USDT or BUSD (both dollar-backed) increases against a local currency, market makers will buy the stablecoin and sell the local currency. This selling pressure on the local currency, amplified by the scale of stablecoin trading, can lead to its devaluation. The study specifically points to the correlation between the trading volume of stablecoins on Binance and the depreciation rates of various local currencies. This implies that the accessibility and liquidity of stablecoins, combined with the trading strategies of market participants, can have tangible impacts on national monetary stability. The findings are particularly relevant for emerging economies where capital flows can be more volatile and local currencies may be more susceptible to external market forces.

While the study does not propose immediate policy interventions, it underscores the growing influence of digital assets, particularly stablecoins, on traditional financial markets and national economies. The research serves as a cautionary note for central banks and financial regulators worldwide, emphasizing the need to monitor the integration of stablecoins into the global financial system and their potential implications for currency stability. The Bank of Korea's findings contribute to a broader academic and policy discussion about the systemic risks associated with the burgeoning digital asset market and its interconnectedness with fiat currencies. The study's methodology involved analyzing trading data and currency exchange rates, establishing a statistical link between stablecoin activity on Binance and local currency performance. This research provides empirical evidence for concerns that have been voiced by various financial institutions regarding the potential for digital currencies to disrupt established financial order and influence monetary policy effectiveness. The implications extend to foreign exchange markets, where the increased use of stablecoins could alter traditional trading patterns and hedging strategies.
