The Nikkei 225 stock average reached a record closing high of 63,272 yen [1] on June 13.

This surge reflects improving investor sentiment driven by hopes for a ceasefire between the U.S. and Iran, which has contributed to a drop in crude oil prices to the low 80-dollar range [2]. The market's movement comes at a critical juncture as both the Bank of Japan and the U.S. Federal Reserve hold key policy meetings this week.

Shingo Ide of the Nissei Basic Research Institute said the market rose toward Friday as the outlook for a cessation of hostilities between the U.S. and Iran brightened [2]. He said prospects for the immediate reopening of the Strait of Hormuz have emerged over the weekend [2].

Market attention now shifts to the Bank of Japan's monetary policy meeting on June 16 [2]. While a rate hike is expected, Ide said the market has already priced in this move [2].

Investors are more focused on the Federal Open Market Committee meeting, with results expected early June 18 Japan time [2]. Specifically, the market is awaiting comments from the new Federal Reserve Chair, Warsh, regarding the central bank's future stance [2].

The Nikkei's recent climb included a daily increase of 529 yen [1], marking the first time the index has closed in the 63,000-yen range [1]. These gains underscore a period of high volatility and growth, though some reports suggest different trajectories for the index's peak during June [1], [3].

The record-breaking performance of the Nikkei 225 suggests that geopolitical stabilization in the Middle East is currently outweighing the risks of tightening monetary policy. By pricing in the Bank of Japan's expected rate hike, investors have shifted their primary focus to the U.S. Federal Reserve. The debut commentary from Chair Warsh will likely determine whether this bullish momentum continues or if the market pivots toward a more cautious stance based on U.S. interest rate trajectories.
