The dollar hit 158.70 against the yen after the Bank of Japan decided to keep rates steady. It's a signal that's rippling through markets right now. When central banks hold rates while others are moving, it reshapes currency flows and asset allocation decisions. For traders watching macro trends, this BOJ move matters because it affects how capital flows globally—whether money stays in yen-denominated assets or seeks yields elsewhere. The stronger dollar can influence everything from commodity prices to emerging market valuations. Those paying attention to macro cycles are already factoring this into their positioning.
