Yen falls to 39-year low of 163 per dollar on Iran tensions, Takaichi plan
The Japanese yen slid to 163 per dollar, its weakest level in 39 years, as oil prices driven up by the Iran war and concerns over Prime Minister Takaichi's fiscal expansion plans weighed on the currency.

The Japanese yen weakened to 163 per dollar, its lowest level in 39 years, as two key pressures combined to drag the currency down: oil prices pushed higher by the Iran war, and market unease over Prime Minister Takaichi's expansionary fiscal plans.
Japan imports the vast majority of its energy needs, so higher oil prices strain both its trade balance and the yen simultaneously. At the same time, investors are worried that the Takaichi government's spending plans could widen the fiscal deficit further, adding another factor eroding confidence in the currency.
A weaker yen raises import costs and adds to inflationary pressure, even as it gives exporters a competitive edge abroad. Markets are watching closely to see whether the Bank of Japan will intervene, with officials so far sticking to language about taking "decisive action if necessary."
