Nikkei 225 Falls as Yen Stays Near 160

The technical picture has also weakened. The Nikkei is now below its 50-day moving average of 66,947.79, with the relative strength index at 34.3, a reading that points to oversold conditions but also reflects clear loss of upward momentum. The MACD has turned negative, while the index sits well below recent highs around 72,366. That combination suggests the market is digesting an outsized advance rather than simply pausing at a technical ceiling.

For investors, the key issue is whether this is a healthy consolidation or the start of a deeper reset in a trade that has been fueled by yen weakness and global enthusiasm for Japanese equities. A softer yen generally boosts exporters such as automakers, industrial firms and technology suppliers, but it also raises the cost of imported energy and food, pressuring households and complicating the policy backdrop for the Bank of Japan. That tension matters for domestic-demand names and for any view that Japan’s reflation story can broaden beyond large-cap exporters.

The yen’s stability near 160 against the dollar is especially important because it keeps alive speculation over possible official intervention, even if authorities have so far been cautious. A sudden strengthening of the currency would likely hit the Nikkei hardest in sectors that have benefited most from translation gains. Conversely, if the yen remains weak and global growth holds up, the pullback could prove temporary and attract buyers back into the market.

The broader message for global markets is that Japan remains one of the most FX-sensitive equity stories in the developed world. For now, the selloff looks more like a reassessment of crowded positioning than a full reversal of the structural bull case. But with the Nikkei still well above its 200-day moving average of 58,763.22, investors are likely to watch the yen, bond yields and any signs of policy pushback as the next major catalysts.
