Investors in Tokyo faced a bruising start to the week as the Nikkei 225 plummeted by two percent during Monday morning trading. This sharp downturn wiped out approximately 23.5 trillion yen, equivalent to about 150 billion dollars, in total market value. The sudden slide reflects a growing nervousness among traders who are reacting to instability across international borders.

Much of the damage was driven by a contagion effect from Wall Street, where a significant rout in American technology shares sent shockwaves through Asia. Japanese firms specializing in semiconductors and consumer electronics felt the brunt of this volatility due to their deep integration into the global artificial intelligence supply chain. As tech valuations dipped in the United States, investors quickly offloaded similar assets in Japan.

Compounding these losses was a simultaneous spike in crude oil prices, which created an additional layer of economic anxiety for the region. Because Japan relies on imports for nearly all of its energy needs, rising fuel costs typically squeeze corporate margins and dampen consumer spending. Together, the tech slump and energy surge formed a perfect storm that left the Nikkei struggling to find any meaningful support early in the session.
