Asian currencies moved in different directions on Tuesday after the PBOC raised its foreign exchange reserve requirement ratio, which weighed on the yuan. The South Korean won strengthened about 0.5% to 1,339.30 per dollar on strong October export data.
The dollar index was near a one-month low as oil fell on diplomatic contacts over the Middle East.
Currency moves in South Korea and China affect the purchasing power of two major Asian importers of feed grains and meal. A stronger won supports Korean import demand, while the yuan's pullback slightly weighs on Chinese buying in dollar terms.
