What Moved the Market

• AI demand resurgence drove tech-led buying. The Nikkei posted its best session in two weeks on Thursday, rising 3.14%, lifted by Nvidia's strong sales forecast, reports of OpenAI's potential IPO, and an averted Samsung strike. SoftBank and other AI-exposed names led gains as investors rotated back into growth names.

• Geopolitical risk had briefly dragged the index below 60,000. On Wednesday, the Nikkei ended below 60,000 for the first time since May 1, pressured by rising interest rates and renewed Iran-related tensions. Thursday's session reversed most of that loss.

• Bond yields continue to weigh on sentiment. The FXEmpire analysis noted that elevated bond yields and oil price concerns remain key headwinds, with the 58,000–60,000 zone a critical support range for the index. The BOJ held rates at 0.5% at its April 28 meeting, with three board members dissenting — a hawkish signal that also supported the yen earlier in the week.

• Japan Inc. heads toward fifth straight record profit year. Listed companies' net profits for fiscal 2025 (ending March) are on track to hit a record high for the fifth consecutive year, according to the Asahi Shimbun, even as Middle East risks cloud forward outlooks.

Losers

Specific daily losers not confirmed in verified sources for May 21. Wednesday (May 20) saw broad selling in tech and Taiwan-exposed names.

Corporate Headlines

Japan's megabanks post record profits, but growth warnings emerge. Japan's largest lenders — Sumitomo Mitsui, Mizuho, and Mitsubishi UFJ — reported record full-year profits, yet analysts are cautioning that sustaining those levels will be challenging. Higher credit costs, current geopolitical risks, and the uncertain path of BOJ rate normalization are seen as headwinds to further earnings expansion.

Toyota navigates tariff headwinds, charts path to growth. Toyota posted operating income of ¥3.8 trillion for fiscal year ending March 2026, despite the impact of U.S. tariffs. In a Q&A session with media on May 18, company executives outlined a path toward sustainable growth, flagging the rapidly changing business environment as the central challenge. The automaker saw a 49% slump in Q4 profits due to tariff impacts but maintained revenue growth.

Japan's auto giants diverge in strategy. A DigiTimes analysis published May 20 highlighted that Toyota and Honda have steadied operations with differing strategies amid U.S. tariff pressures, while Nissan moved into restructuring mode. The divergence has significant implications for suppliers across North America and beyond.

Japan Inc. on track for fifth consecutive record profit year. Despite Middle East tensions clouding corporate outlooks, listed companies' aggregate net profits for fiscal 2025 appear set to reach a record high for the fifth straight year, according to Asahi Shimbun analysis published May 20.

BOJ & Macro Watch

• BOJ holds rates at 0.5%; hawkish signals build. At its April 28 meeting, the BOJ unanimously held rates at 0.5%, though three board members dissented — a more hawkish split than markets expected. The yen strengthened on the announcement. Bloomberg's ongoing Japan yen intervention tracker noted the Ministry of Finance intervened in FX markets for the first time in two years on April 30, with analysts calling on the BOJ to reinforce yen stability with a rate hike in June.

• Japan steps into FX markets; June rate hike expectations building. After the MoF drew "a firmer line in the sand" for the yen at end-April, Reuters reported market participants now expect the BOJ to follow with a rate hike in June to reinforce yen stability. Elevated U.S.-Japan yield spreads remain the structural driver of yen weakness, with some strategists projecting USD/JPY could reach 160 without further BOJ tightening.

• Bond yields a key market risk. Rising JGB yields — a byproduct of global bond market pressure — are weighing on rate-sensitive sectors and continue to test equity valuations. The Nikkei's 58,000–60,000 zone remains the pivotal support level to watch if yields continue rising.

What to Watch Tomorrow

• BOJ policy signals and June meeting positioning: Yen direction and JGB yield moves will remain in focus ahead of the BOJ's anticipated June decision. Any further MoF intervention rhetoric or BOJ governor commentary could sharply move markets.

• Corporate guidance revisions: With fiscal 2025 earnings season largely complete, attention shifts to whether companies will revise FY2026 guidance given ongoing U.S. tariff uncertainty and yen volatility.

• AI thematic momentum: Whether Nvidia-driven optimism sustains into Friday's Asia session will be the short-term test for the Nikkei's Thursday rebound. Weak follow-through in U.S. markets overnight could temper gains.
