The US dollar has experienced a decline amid growing concerns over the US economy, a recent downgrade of the US credit rating, and ongoing trade tensions. This depreciation has been observed alongside a strengthening of the Japanese yen, driven in part by expectations of upcoming US-Japan negotiations. The Nikkei 225 index has fallen for four consecutive days, with a notable drop of around 300 yen at one point, as investors reacted to the US credit downgrade and the stronger yen. The decline in the dollar has also been influenced by cautious market sentiment ahead of the G-7 meeting, discussions on a Trump tax bill, and the US budget deficit. The yen's appreciation has led to increased selling pressure on export-related stocks in Japan, contributing to a broader decline in stock prices. Market participants are closely watching the outcomes of the US-Japan financial talks and the G-7 currency discussions, which are expected to influence currency and equity market movements in the near term.
