The yen weakened significantly after the Bank of Japan (BOJ) decided to maintain its current interest rates, defying investor expectations of a rate hike. This decision has reignited discussions on regulatory policy and central bank strategies, as traders expressed disappointment over the BOJ's lack of clear guidance. The yen's decline has brought it close to levels that might prompt government intervention. In response to the currency's drop, Japanese officials have issued warnings to the markets, emphasizing their vigilance. Additionally, authorities have reaffirmed their dedication to combating the financing of terrorism across all financial sectors, underscoring the government's broader regulatory focus.
