The yen weakened slightly on November 4 in Tokyo, with the dollar at 158.03-158.05 yen at 5 p.m., down 29 sen from the prior day. The yen had briefly strengthened to around 157.37 yen after reports that the Democrats were leading in the U.S. midterm elections, which lowered U.S. long-term rates, but it later gave back gains.
A weaker yen against the dollar makes US-priced commodities and feed imports costlier for Japan, while shifts in US rate expectations after the midterms affect dollar strength and commodity prices broadly.
