Market Snapshot

Note: Verified intraday closing figures for May 9–10 were not available in research data at time of publication. The Nikkei closed at an all-time record of 62,833.84 on May 7, 2026.

What Moved the Market

• SoftBank led losses after Arm Holdings fell overnight. The tech investor SoftBank Group fell 4.56%, acting as the biggest drag on the Nikkei. Its listed subsidiary Arm Holdings tumbled on Wall Street due to smartphone market weakness and concerns about AI chip supply constraints, undermining the AI-driven rally narrative that had powered the index to records.

• Toyota's tariff-hit earnings weighed on sentiment. The world's largest automaker reported a 49% slump in Q4 operating profit on May 8, as U.S. tariffs took a severe toll. Revenue rose just 1.89% year-on-year. Management offered a cautious outlook, reinforcing concerns that tariff exposure could dampen Japan's export-heavy corporate earnings for fiscal 2027.

• Yen volatility kept investors on edge. The Ministry of Finance stepped into the currency market for the first time in two years to support the yen around April 30. Japan is now wagering that a hawkish BOJ shift paired with endorsement from U.S. Treasury Secretary Scott Bessent can give intervention additional bite, according to Reuters.

• Market digesting the record Nikkei surge. After the Nikkei's historic 5.6% single-session surge to 62,833.84 on May 7 — its first-ever close above 62,000 — a consolidation and pullback is underway as investors reassess valuations following the Golden Week reopening rally fueled by strong tech earnings and Middle East peace optimism.

Corporate Headlines

Toyota posts 49% Q4 profit collapse on tariff shock. Toyota Motor Corporation reported fiscal Q4 2026 (ending March 31) results on May 8 showing operating profit fell 49% year-on-year, a far steeper decline than analysts anticipated. Consolidated vehicle sales reached approximately 9,595,000 units — up roughly 233,000 versus the prior year — but revenue growth of 1.89% could not offset the tariff-induced cost surge and intensifying competition. Full-year net revenues totaled 50.684 trillion yen. Toyota's profit outlook for the current fiscal year remains dim, with management citing elevated tariffs and competitive pressures as persistent headwinds.

Sony reports annual profit decline but forecasts record recovery. Sony Group Corporation held its corporate strategy and earnings announcement on May 8, 2026. The electronics and entertainment giant posted a 3.4% drop in annual profit for FY2026. However, management projected a comeback to record profitability in the current fiscal year. Sony's FY2026 continuing operations posted sales of 12.48 trillion yen with 1.45 trillion yen in operating income. A financial services spin-off drove a net loss for the year, paired with a 500 billion yen share buyback program.

Japan bets on BOJ hawkishness and U.S. Treasury backing in yen battle. In a significant policy signal, Japan's government is wagering that the Bank of Japan will shift hawkishly — supported by U.S. Treasury Secretary Scott Bessent — to give yen-buying foreign exchange intervention additional credibility after the Ministry of Finance stepped into markets for the first time in two years. Investors are watching the BOJ closely for a rate hike signal at its June meeting.

BOJ & Macro Watch

• BOJ held rates at April 28 meeting but signaled hawkishness. Three board members dissented at the April 28 BOJ meeting — an unusually large number — and the bank delivered a larger-than-expected upward revision to its fiscal 2026 inflation forecast, citing broader pass-through from higher crude oil prices. The yen strengthened on the announcement. Markets now expect the BOJ to reinforce yen stability with a rate hike in June.

• Ministry of Finance intervened in FX markets for first time in two years. Japan's MoF bought yen around April 30 as the currency slid. Japan is now counting on a coordinated approach — BOJ rate hikes plus diplomatic backing from Washington — to sustainably shore up the yen.

• June BOJ rate decision is the key pivot point. Market participants are now treating the June BOJ meeting as critical. A hawkish shift could stabilize the yen and ease import-cost pressures on Japan's economy, though tighter policy also risks dampening the equity rally.

What to Watch Tomorrow

• BOJ rhetoric and any additional MoF currency intervention signals. With the yen under sustained pressure and FX intervention already deployed, any comments from Governor Ueda or MoF officials could trigger sharp moves in USD/JPY and ripple into equities — particularly export-heavy names.

• Continued corporate earnings flow from Japanese blue-chips. The earnings season is ongoing, and additional results from major Japanese industrials and tech companies could set the tone for whether the post-Golden Week record rally can be sustained or whether the SoftBank/Toyota-led pullback deepens.

• Global risk appetite from overnight U.S. and European sessions. Arm Holdings' weakness on Nasdaq weighed directly on SoftBank and the Nikkei. Watch for any recovery or further deterioration in U.S. semiconductor and AI-related stocks, which have been the primary fuel for Japan's tech-driven equity surge to record levels.
