BlockBeats news, September 18 - According to Nikkei News, in the foreign exchange market from late night on the 18th to the early hours of the 19th Japan time, the yen exchange rate surged significantly, briefly reaching the upper 156 yen level against the US dollar. The Bank of Japan conducted a "rate check" by inquiring about exchange rate levels with market participants.
A rate check is considered a preparatory stage for foreign exchange intervention, heightening market vigilance over potential intervention by the Japanese government and central bank to buy yen and sell dollars.
