# Dollar-yen at 158, why Tokyo threatens but does not intervene

> The dollar-yen rate briefly fell to around 157.4 yen after early Democratic wins in the US midterms weakened the dollar broadly. It returned to about 158.1 by the morning, the level where it has traded since mid-September. Official data show Japan spent no yen on currency intervention in October.

## Why it matters

A stronger dollar against the yen raises the cost of US commodity imports for Japan, while a weaker dollar eases it. The move is short-lived and does not change the wider feed price outlook.
