Won Volatility Response Capacity Sufficient as Seoul Warns Against One-Way FX Moves

Won exchange-rate volatility can widen without exhausting the authorities' room for action. On July 3, Second Vice Minister Huh Jang made clear that immediate market-stabilization measures will be used if trading becomes excessively one-way. The priority is not defending a fixed level but preventing sentiment and demand from amplifying disorderly moves.
Focus on One-Way Moves
The won is sensitive to the dollar, global rate expectations, trade payments and offshore positioning. A 10-won move per dollar changes a $1,000 payment by 10,000 won. For a $1 million import invoice, the same move means about 10 million won, affecting raw materials, overseas study, travel, energy procurement and firms with dollar debt.
Market Impact
Authorities are expected to monitor intraday swings, offshore flow, real demand and bank foreign-currency liquidity. Companies should avoid one-sided bets and review hedging ratios, payment timing and debt maturities. The won will likely track the dollar, US rate expectations, exports and foreign portfolio flows.
