In October the won rose 1.81% against the dollar, versus 0.91% for the offshore yuan and 0.34% for the yen, after a 13.39% surge in July and August. China's central bank raised the FX deposit reserve requirement ratio from 4% to 6%, which pushed the yuan lower, and the won is expected to keep its relative strength while the yen stays range-bound.
The won's relative strength makes dollar-priced imports cheaper for Korean buyers, but the gap with regional currencies is narrowing and China's move to slow yuan appreciation could reduce that advantage.
