July 13, 2026: Tokyo Stock Market Opens the Week with Sharp Volatility
The Tokyo stock market kicked off the week of July 13, 2026, with significant turbulence. The Nikkei 225 closed at 67,242.73, down 1,315.00 points or 1.92% from last Friday. The TOPIX (Tokyo Stock Price Index) ended at 4,007.49, a drop of 28.59 points or 0.71%. Total trading volume for the day reached approximately 1.97558 billion shares.
Intraday, the Nikkei initially climbed, buoyed by Friday’s gains in the US markets, but quickly reversed course. At one point, the index’s loss expanded to over 1,900 points. Both major indices closed lower, ending a three-day winning streak.
How the Escalating Middle East Situation Impacted Japanese Stocks
The immediate trigger for Japan’s sharp market drop on July 13 came from the Middle East. According to Iranian media, on July 12 local time, Iran’s Revolutionary Guard announced a renewed blockade of the Strait of Hormuz, prohibiting passage of all vessels. As one of the world’s most critical energy transit chokepoints, the closure of the Strait drove crude oil prices sharply higher.
WTI crude oil futures for August delivery surged 3.44% to $73.87 per barrel. For Japan’s energy-import-dependent economy, rising oil prices translate to higher production costs across the board. Concerns about inflation eroding corporate earnings spread quickly, becoming a major drag on Japanese equities.
Meanwhile, military tensions between the US and Iran escalated further. US Central Command announced additional airstrikes, and Washington and Tehran issued conflicting statements regarding the reopening of the Strait of Hormuz. Heightened geopolitical uncertainty directly dampened investor risk appetite.
How the Korean Market Crash and Semiconductor Selloff Magnified Japan’s Losses
On July 13, extreme volatility in South Korea’s stock market spilled over to Tokyo. Korea’s KOSPI index closed down 670 points, a staggering 8.96% drop to 6,805.88. The market’s circuit breaker was triggered intraday after losses exceeded 8%.
The core reason for the Korean market’s plunge was the collapse of semiconductor giant SK Hynix, which closed down 15.3%—its largest single-day decline ever. SK Hynix’s American Depositary Receipts (ADR) debuted on Nasdaq on July 10. Gains accumulated in anticipation of the ADR listing were quickly unwound as investors took profits. Samsung Electronics also fell 10.7%.
The sharp downturn in Korea rapidly impacted Tokyo. With Japan and Korea deeply intertwined and competitive in the semiconductor supply chain, the selloff in Korean semiconductor stocks triggered a wave of selling in Japanese peers. The Nikkei’s heavy weighting in semiconductor and AI-related stocks amplified the transmission of external shocks.
Why Semiconductors and AI Stocks Were the Day’s Weakest Sectors
On July 13, semiconductor and AI-related sectors suffered the steepest losses in the Japanese market. Key semiconductor stocks like Kioxia Holdings, Advantest, and Tokyo Electron were the main drags on the Nikkei 225.
Specifically, Kioxia Holdings dropped 12.86%; Advantest fell 3.39%; Tokyo Electron declined 2.25%. Other electronics and semiconductor supply chain names—IBIDEN, TDK, Taiyo Yuden, Murata Manufacturing, FANUC, and Yaskawa Electric—also weakened in tandem.
The collective selloff in semiconductors wasn’t driven solely by geopolitical risk. A deeper factor was the substantial gains these stocks had posted in recent quarters, leaving considerable unrealized profits. With rising external uncertainty, institutional investors rationally opted to lock in gains. Market analysts noted that with US and Japanese earnings seasons starting this week, AI-related stocks may enter a consolidation phase.
Why Bank Stocks Defied the Downturn and Hit Record Highs
Amid the Nikkei’s sharp decline, Japanese bank stocks showed notable resilience, with some major banks even reaching all-time highs.
On July 13, Mitsubishi UFJ Financial Group hit a new intraday record, and its market capitalization surpassed Toyota’s—about ¥42 trillion versus Toyota’s ¥41 trillion—making it Japan’s most valuable company for the day. Sumitomo Mitsui Financial Group also set a new intraday high. Mizuho Financial Group rose 1.32%; Mitsubishi UFJ gained 2.31%; Sumitomo Mitsui advanced 1.63%.
The core rationale behind the banks’ outperformance is a fundamental shift in Japan’s interest rate environment. The Bank of Japan raised its policy rate from 0.75% to 1.0% last month—the first hike since December 2025—bringing rates to a 31-year high. Normalizing rates are widening banks’ net interest margins, as lending rates typically rise faster than deposit rates, directly boosting net interest income.
Mitsubishi UFJ reported net profit attributable to shareholders of ¥2.4272 trillion for fiscal 2025, with a return on equity of 11.3%. The company targets ¥2.7 trillion in net profit for fiscal 2026. According to Bloomberg estimates, every 0.25 percentage point rate hike adds about ¥180 billion in annual net interest income for Mitsubishi UFJ. This quantifiable anchor provides a solid basis for the market’s bank sector re-rating.
At the sector level, among the Tokyo Stock Exchange’s 33 industry groups, banking, securities & commodity futures, mining, precision machinery, and retail were relatively resilient. In contrast, electrical machinery, glass & ceramics, nonferrous metals, and construction lagged. There was clear evidence of rotation from AI and semiconductor stocks into financials and other value sectors.
How the Bank of Japan Independence Debate Is Shaping Market Expectations
Beyond geopolitics and sector rotation, domestic policy uncertainty also played a key role in the July 13 market moves.
Recently, the Bank of Japan’s independence has become a hot topic. In the government’s "Basic Policy on Economic and Fiscal Management and Reform" draft released on June 30, language about "implementing appropriate monetary policy to achieve strong economic growth" was interpreted by markets as government pressure on the BOJ to slow its pace of rate hikes. This, combined with worries about aggressive fiscal expansion and increased government bond issuance, sparked a wave of so-called "Basic Policy Shock" bond selling, sending the 10-year Japanese government bond yield to a nearly 30-year high.
In response, Finance Minister Satsuki Katayama and Economic and Fiscal Policy Minister Minoru Kiyoura both emphasized around July 11 that monetary policy decisions should be left to the BOJ, and the government would not pre-determine the timing or magnitude of rate changes. The government subsequently began revising the policy outline to explicitly affirm central bank independence.
Nonetheless, concerns over fiscal expansion and inflation risks remain. At its core, the debate over BOJ independence reflects market distrust of potential government encroachment on monetary policy autonomy. For equity investors, this means greater uncertainty about the future path of monetary policy—both further rate hikes and political interference are possible. Such uncertainty itself weighs on risk asset valuations.
How Institutions View the Outlook for Japanese Equities
Despite the sharp correction on July 13, major international institutions remain relatively optimistic about Japan’s medium-term market outlook.
On July 13, Citi upgraded its rating on Japanese equities from "Underweight" to "Overweight." The bank believes that as geopolitical risks ease and AI-driven trades become crowded, capital rotation is underway and investors will refocus on whether the rally broadens to other sectors in the second half. Citi maintains year-end targets of 90,000 for the Nikkei and 4,500 for the TOPIX.
Bank of America previously raised its year-end target for Japanese stocks, forecasting about 15% upside for the Nikkei 225 to reach 80,000 by year-end. BofA cites stronger-than-expected AI demand as a key driver.
Citi further notes that upward revisions to tech sector earnings forecasts will power Japanese equities higher, but the current rally remains healthy and not indicative of speculative excess or a bubble. The bank believes Japanese companies’ ability to pass on costs will improve earnings and profit margins, which should boost return on equity and support a re-rating of Japanese stocks.
However, some analysts urge caution. They note that AI-related volatility may remain elevated in the coming quarter, and concentration risk in Japanese equities is rising in the short term. Comments from the finance minister last Friday encouraging large pension funds to increase domestic asset allocations supported financial stocks, but whether this sector continues to attract capital will depend on interest rate trends and the realization of corporate earnings.
Summary
On July 13, 2026, Japan’s stock market saw a significant correction driven by multiple converging factors. The Nikkei 225 closed down 1.92% at 67,242.73, while the TOPIX fell 0.71% to 4,007.49.
Three main themes defined the day’s market dynamics: First, the sudden escalation in the Middle East and the closure of the Strait of Hormuz pushed up oil prices, intensifying concerns about rising costs and inflation for Japanese companies. Second, a semiconductor-led crash in Korea triggered a circuit breaker, with spillover effects hitting Tokyo and concentrated profit-taking in semiconductor and AI sectors. Third, amid Japan’s rate normalization, bank stocks rallied against the trend, with Mitsubishi UFJ overtaking Toyota as the country’s most valuable company and a clear rotation from growth to value stocks gaining momentum.
Additionally, uncertainty over the BOJ’s independence and divergent signals from major global institutions’ ratings and target prices are key variables for future market trends. Japanese equities are now at the intersection of geopolitical risk, policy uncertainty, and structural revaluation.
