Nikkei Flat as Tech Gains Offset SoftBank Plunge Amid Iran Tensions
The Nikkei 225 closed virtually unchanged at ¥38,749, gaining just 0.04% in a session marked by sharp divergence between technology winners and geopolitical losers on Tuesday, May 12, 2026.
Without USD/JPY data available, currency impacts on exporters remained unclear, though the mixed performance of major export-dependent names like Toyota (-1.99%) and Honda (-2.16%) suggested potential headwinds from yen strength or broader risk-off sentiment.
The session’s narrative was dominated by escalating tensions in the Middle East, as hopes for a US-Iran peace deal evaporated following reports that former President Trump rejected what he termed a “garbage” Iranian proposal. This geopolitical uncertainty rippled through global markets, with oil prices rising on supply concerns and risk assets showing mixed reactions.
Technology stocks emerged as the day’s clear winners, with Nintendo surging 5.93% to ¥1,743.19 and Sony Group climbing 5.66% to ¥3,352.54. The tech rally appeared disconnected from the broader geopolitical concerns, possibly driven by sector-specific catalysts or defensive positioning into growth names. Orix led all gainers with an impressive 8.92% jump to ¥5,785.45, while industrial giant Daikin Industries added 3.27%.
The session’s biggest casualty was SoftBank Group, which plummeted 7.10% to ¥2,947.84, likely reflecting investor concerns about the conglomerate’s exposure to global tech investments amid rising geopolitical uncertainty. The decline underscored how Masayoshi Son’s empire remains vulnerable to shifts in global risk sentiment, particularly given its significant exposure to Chinese and other international markets.
Automotive giants Toyota and Honda both retreated, falling 1.99% and 2.16% respectively, as investors weighed the potential impact of Middle East tensions on global supply chains and energy costs. The declines came despite Japan’s automotive sector typically benefiting from higher oil prices through improved hybrid and electric vehicle demand.
Adding to domestic corporate challenges, snack manufacturer Calbee reportedly switched to monotone packaging due to Iran-related ink shortages, highlighting how geopolitical tensions can create unexpected supply chain disruptions for even seemingly unrelated Japanese companies.
Looking ahead to monetary policy, the Bank of Japan’s next meeting on April 28, 2026 remains in focus, with markets expecting Governor Ueda to maintain current rates while closely watching his commentary on US-China trade tensions. Any dovish signals could weigh on the yen, while hawkish surprises might provide support to the currency and pressure export-heavy indices.
Tuesday’s session ultimately reflected the complex crosscurrents facing Japanese equities, where strong domestic tech performance collided with geopolitical headwinds and mixed signals from traditional export sectors, leaving the benchmark index treading water despite significant individual stock movements.
