The yen rallied sharply on Sept 22 after Japanese monetary authorities intervened in FX markets for the first time since 1998. The dollar fell to a low of 140.31 yen from a 24-year peak near 145.9.
A stronger yen eases the cost of dollar-priced imports such as feed ingredients for Japan, but a weaker dollar generally supports dollar-denominated grain and oilseed prices. The effect on feed prices is modest and may fade if intervention fails.
