周三，日经225指数下跌0.05%，收于40655点，而更广泛的东证指数上涨0.4%，收于2920点，随着投资者为日本央行最新的货币政策决定做准备，日本股市正在努力寻找明确的方向。由于最近美国关税对经济的影响存在不确定性，人们普遍预计央行将在周四保持利率不变。然而，央行可能会在其季度展望中上调通胀预测，反映出持续的价格压力。投资者还权衡了美国和中国再次延长关税休战的前景，而商务部长霍华德·卢特尼克证实，其他国家的8月1日关税最后期限仍然不变。涨幅较大的股票包括藤仓（+8.9%）和古河电气（+6.8%），而Keyence（-4.8%）和樱花互联网（-7.6%）则大幅下跌。

The Nikkei 225 Index shed 0.05% to close at 40,655 while the broader Topix Index gained 0.4% to 2,920 on Wednesday, with Japanese shares struggling for clear direction as investors braced for the latest Bank of Japan monetary policy decision. The central bank is widely expected to keep interest rates unchanged on Thursday amid uncertainty over the economic fallout from recent US tariffs. However, the central bank is likely to raise its inflation forecast in its quarterly outlook, reflecting ongoing price pressures. Investors also weighed prospects of another extension to the tariff truce between the US and China, while Commerce Secretary Howard Lutnick confirmed that the August 1 tariff deadline for other countries remains firm. Notable gainers included Fujikura (+8.9%) and Furukawa Electric (+6.8%), while Keyence (-4.8%) and Sakura Internet (-7.6%) posted sharp losses.
