Tokyo – August 4, 2025
Japanese equities tumbled on Monday, marking their steepest decline since April, as concerns over the health of the U.S. economy and renewed trade tensions rattled global investor confidence.
The benchmark Nikkei 225 Index fell 1.8%, heading for its worst single-day performance since April 11, while the broader Topix Index lost 1.5%. Japanese banking shares were hit particularly hard, with the sector’s sub-index diving 4.2%, reflecting deepening investor anxiety.
The sharp downturn followed a rough session on Wall Street, where U.S. stocks slid after disappointing jobs data and worries that tariff tensions may intensify. According to the U.S. Labor Department, only 73,000 nonfarm jobs were added in July — significantly below market expectations — and June’s figures were also revised downward.
At the same time, U.S. Trade Representative Jamieson Greer signaled that the sweeping tariffs imposed last week by President Donald Trump on dozens of countries — including Canada (35%), Brazil (50%), India (25%), Taiwan (20%), and Switzerland (39%) — are unlikely to be lifted anytime soon. That has fueled renewed fears of a global slowdown, particularly in trade-dependent economies like Japan.
On the domestic political front, investors were further unnerved by mounting speculation around Prime Minister Shigeru Ishiba’s future. Following a stinging electoral defeat last month in which the ruling coalition lost its majority in the upper house, pressure within Ishiba’s Liberal Democratic Party (LDP) has grown. While Ishiba has repeatedly rejected calls to step down, the whispers of a possible resignation are getting louder.
“We’ve had weak jobs data out of the U.S., and that’s darkened sentiment significantly,” said Kenji Abe, chief strategist at Daiwa Securities. “On top of that, there’s a real possibility that Prime Minister Ishiba might be forced out. That’s something markets are watching closely.”
Losers overwhelmingly outnumbered gainers on the Nikkei, with 189 stocks in the red compared to just 34 advancers. Credit Saison was the day’s worst performer, plunging 8.2%, followed closely by Yamaha, which fell 7.9%.
Among the few bright spots, Socionext, a chipmaker, jumped 3.9%, while Hoya Corp, known for its precision optics, gained 2.7% — both benefiting from expectations of sustained demand in the tech sector despite broader market jitters.
