Japan's equity benchmarks, the Nikkei 225 and Topix, opened the week at all-time highs, propelled by a weekend agreement between the United States and Iran that sent crude oil prices tumbling. The Nikkei 225 reached ¥69,593, while the Topix climbed to ¥4,023, as investors embraced a risk-on mood. This article outlines the four primary catalysts that will shape Japanese stock market direction over the coming days.
1. US-Iran Deal and Oil Price Plunge
The most immediate catalyst is the US-Iran deal finalized on Sunday, which ended hostilities and reopened the Strait of Hormuz. President Donald Trump celebrated the development, which drove West Texas Intermediate (WTI) crude toward $80 per barrel and pushed Brent down more than 30% from its 2025 peak. For Japan, a major importer of Middle Eastern oil, lower energy costs are a significant tailwind. The country is expected to increase crude purchases to replenish strategic reserves, while the drop in oil prices should help cap inflation, which has remained elevated in recent months.
2. Bank of Japan Interest Rate Decision
The Bank of Japan (BoJ) announces its monetary policy decision on Tuesday, with the yen trading near 160 against the US dollar—a level that previously triggered a ¥30 billion intervention. Most analysts anticipate a 0.25% rate hike, which would bring the policy rate to 1%, the highest in over three decades. This expectation has already pushed Japan's 10-year bond yield to 2.80%. However, the BoJ may opt to pause given the recent oil price decline and Middle East developments. The decision will be closely watched for its impact on the yen and equity valuations.
3. Federal Reserve Interest Rate Decision
The Federal Reserve's policy meeting on Wednesday follows the BoJ's decision. Economists widely expect the Fed to hold rates steady, citing the need for more time to assess economic conditions. Recent US data showed 172,000 jobs added in May, while consumer and producer inflation stood at 4.2% and 6.5%, respectively—both above the Fed's 2% target for over five years. A dovish stance could support risk assets globally, including Japanese equities.
4. Key Japan Macroeconomic Data
Japan releases important economic data this week. On Wednesday, trade figures for May are expected to show exports rising 16% year-over-year and imports climbing 12%. On Friday, the consumer price index (CPI) is forecast to show headline inflation at 1.6% and core inflation steady at 1.9%. These numbers will provide further clues on the BoJ's policy path and the health of the Japanese economy.

Investors should monitor these events closely, as they will likely dictate the near-term trajectory of Japanese equities. The combination of lower oil prices, potential BoJ tightening, and steady Fed policy creates a complex but potentially favorable environment for Japan's stock market.
