Traders remained on high alert for possible intervention to support the yen Monday after it touched a 32-year low and neared the key psychological ¥150 per dollar level.

The yen was little changed around ¥148.60 in Tokyo trading after nine straight weeks of losses. Finance Minister Shunichi Suzuki reiterated to reporters on Monday that the country will take bold action if there are speculative foreign exchange moves.

"We’re constantly watching the foreign exchange market moves with a sense of urgency,” he said. "If there are excessive moves triggered by speculators or others, there’s absolutely no change in our stance that we’ll take bold action.”
