Japan’s Nikkei share index declined on April 9, 2026, as earlier optimism over a potential United States–Iran ceasefire weakened. Investors turned cautious following a strong rally in the previous session. According to market data, the Nikkei fell 0.4 percent to 56,036.75 points at 02:00 GMT, while the broader Topix index dropped 0.5 percent to 3,755.52 points. The decline raised concerns that the market’s four-day upward trend might end.

The previous session had seen the Nikkei jump 5.4 percent to its highest level in more than a month, driven by expectations that the Strait of Hormuz could reopen after Donald Trump agreed to a two-week ceasefire with Iran. Overnight, Nikkei 225 futures traded above 57,000 points on the Chicago Mercantile Exchange, reflecting earlier optimism that has since cooled.

If the current trend continues, Japan’s stock market may see a pause in its recent rally as investors await clearer signals regarding the ceasefire situation.
