The Japanese yen has experienced a significant drop, reaching its lowest level against the US dollar since 1990, with the $USDJPY rate now at 151.88. This decline has sparked speculation that Japan may intensify efforts to slow the yen's fall. The currency briefly touched ¥151.97 to $1, marking its weakest position in approximately 34 years. This situation underscores concerns about central bank policies, especially in light of recent rate hikes amid rising inflation.
