Yen hits 40-year low as officials signal intervention readiness
The Japanese yen fell to about 162 per dollar, its weakest since 1986, prompting officials to warn they will act against excessive moves; authorities signaled readiness to intervene as the BOJ raised rates to 1% and Japan spent over 11.7 trillion yen in FX reserves to support the currency, reflecting persistent weakness driven by yield differentials and carry trades.
