Bank of Korea Flags Stablecoin Pressure on Local FX

A Bank of Korea study has added fresh evidence that dollar-backed stablecoins can influence foreign-exchange markets beyond crypto trading venues. The central bank found that buying pressure in Binance-paired currencies tends to coincide with local currency depreciation, as market makers adjust positions to stay balanced.

The mechanism is straightforward. When traders buy stablecoin-linked crypto assets, dealers and liquidity providers often need to source dollars or hedge exposure. That can create sustained demand for foreign currency against the local unit, especially in markets with thinner liquidity or less developed capital controls.

The finding matters because stablecoins are increasingly used as a settlement layer for trading, payments and cross-border transfers. Their growth has been a major support for crypto market liquidity, but the Bank of Korea study suggests that the same flows can transmit pressure into domestic FX markets when demand is concentrated and persistent.

The report does not imply that stablecoins alone drive currency weakness. Broader macro forces, interest-rate differentials, trade balances and risk appetite remain the main determinants of exchange rates. Still, the study highlights a channel regulators are likely to monitor more closely as stablecoin usage expands and dollar-linked digital assets become more embedded in market structure.
