What Moved the Market

• SoftBank Group fell 4.56%, becoming the heaviest drag on the Nikkei as U.S.-listed shares of Arm Holdings tumbled overnight on concerns about smartphone market weakness and AI chip supply chain tensions. SoftBank had surged over 16% in the record-setting May 7 session.

• Toyota's catastrophic earnings miss weighed on the broader index and auto sector sentiment. The world's top automaker reported Q4 FY2026 operating profit collapsed 49% year-over-year, as U.S. tariffs overwhelmed a modest 1.89% revenue gain. The results are sending shockwaves through Japan's manufacturing backbone.

• Sony Group posted FY2026 results with continuing sales reaching 12.48 trillion yen and 1.45 trillion yen in operating income, but a financial services spin-off drove a net loss. Sony announced a 500 billion yen share buyback program. Annual earnings guidance missed expectations even as FY25 continuing profit rose 13%.

• Yen intervention risk remains elevated. Japan's Ministry of Finance is believed to have intervened in FX markets during the Golden Week holidays, and a former BOJ official told Reuters that Japan will step back in if the yen slides below the psychologically key 160-per-dollar level. The BOJ is now under market pressure to reinforce yen stability with a rate hike in June.

Corporate Headlines

Toyota FY2026 — Tariff Shock Hammers Profits. Toyota Motor Corporation reported Q4 FY2026 earnings on May 8 that badly missed expectations. Fourth-quarter operating profit collapsed 49% year-on-year, driven by aggressive U.S. tariff hikes that overwhelmed a 1.89% rise in revenue for the quarter ended March 2026. The results highlighted the vulnerability of Japan's manufacturing sector to escalating trade frictions, and Toyota's forward guidance has been substantially dimmed. The automaker flagged increased competition alongside tariff headwinds as compounding pressures heading into FY2027.

Sony Group FY2026 — Strong Operations, Spin-Off Drives Net Loss. Sony Group reported full-year results on May 8 showing continuing operations sales of 12.48 trillion yen and operating income of 1.45 trillion yen. However, the planned spin-off of Sony's financial services division created a significant accounting loss at the net level. To offset investor concern and signal confidence, Sony simultaneously announced a 500 billion yen share buyback program. Annual guidance missed Street expectations despite the 13% rise in FY25 profit.

SoftBank / Arm Selloff. SoftBank Group, which had been a primary engine of the Nikkei's record-breaking May 7 session — surging over 16% on that single day — reversed sharply as overnight losses in U.S.-listed Arm Holdings spilled over into Tokyo trade. Arm's decline was attributed to concerns about weakening smartphone market dynamics and uncertainty over AI chip supply chains.

BOJ & Macro Watch

• Japan reportedly intervened in FX markets during Golden Week. According to Reuters, citing a former BOJ official, Japan's Ministry of Finance stepped into foreign exchange markets during the holiday period to defend the yen. The official stated Japan will act again if USD/JPY breaks below the 160 level. Markets are treating 160 as the Ministry's line in the sand.

• BOJ faces mounting pressure for a June rate hike. With the MoF drawing a firmer line on yen defense, analysts now argue it is "the turn for the BOJ to reinforce yen stability with a rate hike in June," according to Reuters reporting. The BOJ held rates at its late-April meeting, though three board members dissented and the bank revised FY2026 inflation forecasts higher due to pass-through from crude oil prices — a combination that markets are reading as hawkish.

• JGB market: bonds rallied sharply on May 7 alongside the Nikkei's record-breaking session as markets returned from Golden Week holidays, catching up with optimism over strong technology earnings and Middle East peace deal signals. The 10-year JGB yield trajectory remains a key variable ahead of any potential June BOJ action.

What to Watch Tomorrow

• Remaining large-cap earnings reports: The Japan earnings season is in full swing. Watch for additional blue-chip results that could set the tone for the broader market. Sony's guidance and Toyota's tariff impact commentary will continue to be digested by investors.

• USD/JPY and intervention signals: With the yen near the 160 threshold, any further weakness could trigger additional MoF intervention. Traders will be monitoring Japanese government commentary and intraday FX moves closely.

• U.S.-Japan trade developments: Toyota's earnings catastrophe has put a sharp spotlight on the bilateral tariff situation. Any signals from Washington or Tokyo regarding trade negotiations could move auto and manufacturing names sharply in either direction.
