The Nikkei 225 opened Tuesday's session at 408.43, below Monday's close. That puts the index back under levels it held for most of the past two weeks.
The immediate pressure point is the Bank of Japan. Reports indicate the central bank is days away from a rate decision, and expectations are coalescing around a hike to 1.25%. A tighter policy stance raises the cost of carry for domestic borrowers and, critically, tends to strengthen the yen.
A firmer yen is a particular headache for the export-heavy companies that anchor this index. When the yen rises against the dollar or euro, the overseas revenues those companies bring home shrink in yen terms, compressing margins without anything changing on the factory floor. That dynamic is repricing Japanese equities this week.
The index climbed from the mid-400s to nearly 430 before this pullback, so the 0.7% opening drop lands at a technically sensitive spot. How the session closes relative to Monday will signal whether the selling reflects genuine concern about the rate path or a routine reset ahead of the decision.
