Yen Slides Toward 160 Per Dollar Despite Heavy Tokyo Intervention

The Japanese yen weakened beyond 159.5 per dollar this week, moving toward the 160 level that previously prompted official intervention, according to Trading Economics. The decline persisted even after Tokyo spent roughly 11.7 trillion yen on currency support between late April and late May, a measure of how persistent the pressure has become.

The depreciation is visible in real economic behavior far from Tokyo. The Israeli business daily Globes reported that the weaker yen, combined with more accessible flights, has turned Japan from an expensive, unusual destination into a mainstream one for Israeli travelers, with tour operators describing a sharp increase in bookings even outside peak seasons. It is a small but concrete example of how a currency's decline redirects global spending.

The root cause is monetary. Japan maintains one of the lowest policy rates among major central banks, and that gap with the rest of the world keeps capital flowing out of the yen. The renewed weakness has strengthened expectations that the Bank of Japan could raise rates later this month, especially as energy costs tied to Middle East tensions add to inflation.

From the perspective of sound-money economics, the yen is a case study in the consequences of prolonged ultra-loose policy. Years of suppressed interest rates and large-scale asset purchases have left the currency vulnerable, and intervention addresses the symptom while the underlying rate difference drives the trend.
