Nikkei 225 Forecast: BOJ Rate Hike Expectations and Weak Yen Keep Index Volatile

Nikkei 225 trades sideways on Friday due to the holiday session in major markets. Despite ongoing uncertainty from the US-Iran war, the index ended up with a gain of 5.04% last week, as investors responded to strong sector performance and shifting macro indicators. Markets have shifted their attention to the increasing rate expectations by the Bank of Japan and the effects of the Middle East war. I believe that these combined forces are setting the stage for further volatility of the index in the near future.

BOJ Policy Shift and Rising Inflation Shape Market Outlook

The Bank of Japan has been encouraged by the International Monetary Fund to keep on increasing interest rates even as geopolitical risks rise. The markets are already pricing 70% chance of a rate increase as early as April. This is a change following the termination of long-term stimulus by BOJ in 2024 and the increase in rates several times, including in December.

The inflation pressures are accumulating as a result of increasing oil prices and a weak yen. The yen has weakened against the dollar, which raises the cost of imports to the Japanese economy. Meanwhile policymakers are also worried that increased energy prices will contribute to further inflation.

The chart below shows that inflation has dropped from 3.7% to 1.3% in early 2026. This moderation indicates that the price pressures are easing from recent highs. Nevertheless, inflation is still vulnerable to external events like a surge in oil prices and a weak yen. This is the reason why the Bank of Japan has been indicating slow rate increases, even as growth is decelerating.

Nikkei Gains Driven by Sector Strength Amid Rising Uncertainty

While there are still many factors that create uncertainty for equity investors around the world, Japan’s equities have shown resilience. Gains in real estate, banks, textiles and other sectors have driven a portion of this strength. As such, it was no surprise to see the Nikkei 225 gained 5.04% last week. In addition, individual equities also demonstrated significant strength. Taiyo Yuden Co., Ltd., Archion Corp, and Furukawa Electric Co., Ltd. were the main performers last week.

On the other hand, several sectors show weakness. For example, Nitori Holdings Co Ltd dropped 5.12% on Friday to a new 5 year low of 2,379.00 yen. This decline can be compared to the declines experienced by Chugai Pharmaceutical Co., Ltd., down 4.56%. On the other hand, beverage manufacturer Kirin Holdings Co., Ltd., was down 2.92%.

Overall, the market shows strong volatility due to high levels of uncertainty in global oil prices and investor sentiment on inflation and policy.

Nikkei 225 Technical Analysis: Key Levels in Focus

The long-term outlook for the Nikkei 225 remains strongly bullish, as the price has surged to a record high in February 2026 at 60,000. However, due to the U.S.-Iran war and the broader global equity correction, the index dropped to a low of 50,400.

The index has traded within the ascending broadening wedge pattern since it formed the low in 2012 and broke the pattern in September 2025. However, the recent correction from the record high in February 2026 has strong support around the 46,000 to 47,000 level. If the index drops to this level, then it may offer a strong buying opportunity in stocks for long term investors.

The chart below shows that the Nikkei 225 index has been trading within the ascending channel pattern since April 2025. However, the prospect of U.S.-Iran war has broken the ascending channel pattern in March 2026.

Despite this breakdown, the Nikkei index has been consolidating between the 50- and 200-day SMA and is looking for direction. A break above the 55,600 level will indicate a strong rally in the index. However, a break below the 50,000 level will indicate further downside in the Nikkei index toward the 46,000 level.

Bottom Line

Nikkei 225 is supported by strong sector performance, but rising macro risks are contributing to volatility. The market is getting mixed signals due to the expectation of rate hikes by the Bank of Japan, a weak yen and oil-induced inflation. The bigger picture is constructive as long as the index is above the key support zone of 50,000. Any break above 55,600 would result in a powerful rally, whereas a break below 50,000 would signal a drop to 46,000.
