Yen Weakness Sparks Warning of Potential Intervention

Japan's finance minister, Satsuki Katayama, has indicated that the country may intervene in foreign exchange markets again as the yen weakens toward ¥160 per U.S. dollar.

The warning comes after the yen declined for nearly two weeks despite the Bank of Japan raising its policy rate to 1.25%, the highest level in 31 years.

Japanese authorities have stepped up monitoring of currency markets, conducting exchange-rate checks with banks last week.
