Finance Minister Shunichi Suzuki issued a fresh warning Monday about the weakening yen, saying that authorities stood ready to respond to speculative moves behind the currency's falls.
The remark came after the government's decision Thursday to intervene in the currency market to stem yen weakness, by selling dollars and buying yen for the first time since 1998.
Suzuki also told a news conference the government and the Bank of Japan were on the same page in sharing concerns about the currency's sharp declines.
