Japan shuddered Wednesday (22/6) after the dollar sank below the important psychological barrier of 100 yen for the first time in post-war history, threatening to derail the fragile economic recovery now taking shape. Despite reported intervention by the Bank of Japan, estimated to have bought hundreds of millions of dollars Wednesday in a desperate bid to halt the yen's latest appreciation, the dollar closed at 100.65 yen, barely above its opening level of 100.35 yen and down from 102.15 yen at Tuesday's finish. The yen's overnight surge pushed the dollar below 100 yen for the fist time since American occupation authorities generously set the post-war level of the Japanese currency at 360 yen to the dollar in 1949. The yen's latest surge came only a day after the government announced that gross domestic product (GDP) in the three months to March grew by one percent from the previous quarter, the strongest rate of expansion in three years.
