On Tuesday, Japan’s Finance Minister Satsuki Katayama reportedly said the country had a “free hand” in dealing with the yen’s recent sharp depreciation, signaling a currency intervention was not off the table.

The yen weakened sharply on Friday, despite the Bank of Japan raising interest rates to a 30-year high, hitting a low of 157.77 against the dollar before strengthening on Monday and Tuesday. It was last trading at 156.14.

Katayama said that the Japanese currency’s fluctuations do not reflect economic fundamentals, describing them as “speculative.”
