According to CoinMeta, Japanese Finance Minister Masayuki Katsumura will announce on Monday that Tokyo and Washington have taken joint action to prevent the depreciation of the yen. Two Japanese government officials stated that Japanese and American authorities have conducted multiple rounds of yen buying operations in the market, which is the first such joint intervention since 2011. The aim is to boost the yen from its lowest level against the US dollar since 1986, and the actions are still ongoing.
