Yen Sinks Past 162 to Near 40-Year Low as Rate Gap Overwhelms BOJ Hike

The yen slid into the upper-162 range against the dollar on June 30, its weakest in roughly 39.5 years. What matters is that the Bank of Japan only just raised its policy rate to 1% in late May, the first such level in 31 years, yet the currency fell anyway, because exchange rates track the gap between two countries' rates, not one side's move. With markets betting the new Fed chair leans hawkish while Japan's 1% still sits far below US levels, the carry incentive to sell yen persists. For readers eyeing Japan, this cuts both ways. Travel, shopping and property are at a generational discount in dollar or NT-dollar terms, handing buyers an extremely favorable entry. But Japan imports most of its energy and food, so a weaker yen feeds import-driven inflation that erodes the purchasing power of yen-earners and raises costs for hospitality operators. In equities the split is clear: exporters such as autos, machine tools and chip-gear see overseas revenue inflate, while import-reliant domestic names lose margin. Watch three things next: any faster-hike signal from the BOJ in July, whether US hike expectations cool, and whether Tokyo intervenes at these weaker levels. Near a 39.5-year low, the odds of verbal or actual intervention rise sharply.
