Won Posts 15.41 Percent Gain, Leading G20 Currencies

The South Korean won appreciated 15.41 percent in the third quarter of 2023. This performance places it first among the twenty major economies. The currency dropped from 1,551.2 won per dollar on July 1 to 1,344.1 won by late September. The decline in the exchange rate represents a gain of 207.1 won. This appreciation is roughly three times the strength of the Japanese yen. The yen recorded a 5.84 percent gain over the same period.

Other G20 currencies showed mixed results during the quarter. The Australian dollar rose by 4.00 percent. The Canadian dollar increased by 2.48 percent. The euro gained 1.93 percent against the U.S. dollar. The British pound and Chinese yuan posted smaller gains. The Russian ruble depreciated by 7.85 percent. The Swiss franc fell by 0.87 percent. The U.S. Dollar Index remained nearly flat with a 0.02 percent change.

Drivers of Sharp Won Appreciation

Several factors contributed to the strong performance of the won. Slowing U.S. inflation reduced concerns about aggressive monetary tightening. The Bank of Korea raised interest rates, narrowing the yield gap with the United States. Foreign investors slowed their selling of South Korean stocks. Expectations of dollar inflows from SK Hynix's ADR listing also supported the currency. These elements combined to drive the rapid exchange rate decline.

Volatility and Market Impact

The rapid appreciation has increased market volatility. The average daily fluctuation reached 67.8 won during the period. This level matches the volatility seen in 2008 during the global financial crisis. It is higher than the 61.2 won average recorded in 2009. Such swings complicate pricing and hedging for exporters. Companies face pressure as dollar revenues convert to fewer won. Price competitiveness in certain sectors may weaken due to the strong currency.

Future Exchange Rate Outlook

Market participants await the U.S. Federal Reserve decision on September 15 and 16. Rising oil prices and U.S. inflation support expectations of rate hikes. WTI crude reached $102.48 per barrel, its highest since May. Brent crude hit $107.63 per barrel. The 10-year U.S. Treasury yield approaches 5 percent. KB Kookmin Bank predicts a potential rebound to 1,360-1,370 won if rates rise. Hana Bank expects gradual strength to continue, with the rate possibly falling to 1,310 won by year-end. Dollar selling by semiconductor exporters may limit further depreciation. GN markets/fx (en-US) reports that these factors will shape the near-term direction. The medium-term trend remains supported by structural trade balances.
