The won-dollar exchange rate fell during daytime trading on Seoul's FX market as domestic chipmakers sold dollars earned from overseas sales. It then rebounded in overnight trading, when that dollar supply shrinks and global financial conditions weigh more.
The won closed the most recent session at 1,339.5 per dollar, 2.7 won weaker than the daytime close.
Exchange-rate swings change the won cost of imported feed ingredients such as corn, soymeal and fishmeal, which Korean buyers pay for in dollars. Short-term moves of this size have a small effect on feed costs, but a sustained weaker won would raise them.
