Japan’s benchmark surged 4.19% on Thursday, its biggest single-session gain since October 2023, as AMD’s Q1 revenue beat of $460M above consensus and a US–Iran ceasefire signal compressed three days of missed Golden Week gains into one session.
Japan Markets Reopen to Historic Session After Golden Week

Japan’s stock market made history on Thursday. The Nikkei 225 closed at 62,009.59, crossing the 62,000 mark for the first time ever, after investors returning from a three-day Golden Week holiday rushed to catch up with a global rally that had built in their absence, according to Reuters. The 4.19% single-day advance was the index’s sharpest since October 28, 2023, when it gained 4.49% on BoJ policy relief. The broader TOPIX advanced 2.12% to 3,807.84.
AMD Blowout and Iran Talks: The Two Catalysts That Moved Everything
The trigger was twofold. Advanced Micro Devices reported Q1 2026 revenue of $10.3 billion on May 5, up 38% year-on-year and $460 million ahead of the $9.84 billion Wall Street consensus, with Q2 guidance of $11.2 billion that exceeded the Street’s top-end estimate of $10.9 billion, per AMD’s IR press release. Separately, President Trump warned Iran of further military action while signalling that a deal was within reach — a combination markets chose to read as progress toward resolution. US indices hit fresh records. Europe surged. By the time Tokyo opened Thursday, three days of missed gains had loaded into a single session open.
SoftBank Leads the Board With Best Day Since March 2020
SoftBank Group was the session’s standout. Shares jumped 16.45%, the company’s best single day since March 2020, per CNBC, a direct read-through from AMD’s blowout numbers given SoftBank’s heavy AI investment exposure through Vision Fund. That one stock alone moved the index needle meaningfully given its price weighting in the Nikkei 225.
Semiconductor Supply Chain Stocks Surge in Lockstep With AMD
Semiconductor supply chain names followed close behind. Ibiden Co., which makes IC substrates at the base of every advanced chip package, surged approximately 17%. Mitsui Kinzoku, which supplies copper foil for PCBs and specialty alloys used in semiconductors, gained approximately 17%. Renesas Electronics rose approximately 13%, per CNBC, with Yahoo Finance confirming the close. Tosoh Corporation, a chemical and materials firm supplying process gases to fabs, added 11%.
Bonds and Equities Rally Simultaneously — First Time Since November 2024
What stood out structurally was a simultaneous bond rally. Japanese government bonds strengthened after domestic markets reopened, with the benchmark 10-year JGB yield falling 1.5 basis points to 2.485% and the 5-year easing 0.5 basis points to 1.870%, per Reuters. Bonds and equities rallying in the same session has not occurred since November 13, 2024 — it signals genuine cross-asset relief buying rather than a rotation, reflecting the market’s collective exhale on both the Iran situation and the AI earnings cycle holding up.
Yen Holds Steady; Honda and Inpex Slip as Export and Energy Stocks Lag
The yen held at 156.33 per dollar, largely steady after briefly touching a 10-week high near 155 the previous session on speculation that Japanese authorities had intervened to support the currency, per Reuters. The stable yen cut both ways Thursday: exporters like Honda Motor slipped 0.7% on concern that yen firmness compresses overseas earnings translated back to yen. Inpex Corporation, Japan’s largest oil and gas explorer, fell 5.9% as crude eased on hopes of a Middle East resolution, the mechanical flip-side of the rally’s own catalyst.
BoJ’s Rate Hike Case Weakens as Iran Deal Eases Energy Inflation Pressure
One item that didn’t make most front pages: Bank of Japan meeting minutes from March, released Thursday, showed that “many” board members — not a fringe view — believed further rate hikes would become necessary if energy costs linked to Middle East tensions remained elevated for a prolonged period, per Reuters. The BoJ kept its short-term policy rate at 0.75% at both the March 18–19 and April meetings. With crude now softening on Iran deal expectations, that stated energy-inflation justification for tightening has materially weakened. At the May BoJ meeting, the key language to watch is whether “many members” on energy-driven inflation shifts to “some members”, a downgrade that would signal the rate path is being pushed out.
Wall Street Closes at Fresh Records; S&P 500 Hits 7,365
On Wall Street, the S&P 500 closed at a fresh all-time high of 7,365.12, up 1.46%, while the Nasdaq Composite gained 2.02% to 25,838.94, per CNBC. The Dow added 612.34 points (1.24%) to 49,910.59. AMD’s stock itself rose 18.61% to $421.39. The session’s two largest non-AMD movers — Super Micro Computer (+24.54% to $34.66) and DaVita (+23.46% to $193.88), had different drivers: Super Micro rode AMD’s chip supply chain halo, while DaVita surged on its own earnings beat. On the losers’ side, CDW fell 20.32% to $109.00 after guiding below consensus on IT spending softness, Cencora dropped 17.38% to $252.74; and Bio-Techne slid 16.36% to $47.41, per Appreciate Markets data as of 01:30 AM IST.

What is the Nikkei 225 all-time high as of May 2026?
The Nikkei 225’s all-time closing high is 62,009.59, set on May 7, 2026. That surpasses the previous record of approximately 60,000 set in early 2026 and the prior long-standing peak of 38,915.87 reached in December 1989 during Japan’s asset bubble. Thursday’s close also cleared the 62,000 intraday milestone for the first time in the index’s history. Source: Reuters, Nikkei Indexes.
What did AMD report in Q1 2026 earnings?
AMD reported Q1 2026 revenue of $10.3 billion, up 38% year-on-year and $460 million above the Wall Street consensus of $9.84 billion. Q2 2026 guidance of $11.2 billion exceeded analyst top-end estimates of $10.9 billion. The company’s data centre GPU segment drove most of the upside. AMD shares rose 18.61% to $421.39 on the result. Source: AMD IR press release, May 5, 2026.
Which Japanese stocks gained the most on May 7, 2026?
SoftBank Group led with a 16.45% gain, its best day since March 2020, driven by AI investment exposure through Vision Fund. Ibiden Co and Mitsui Kinzoku each surged approximately 17%, and Renesas Electronics rose approximately 13%, all semiconductor supply chain names reacting directly to AMD’s results. Tosoh Corporation added 11%. Source: CNBC, Yahoo Finance, Reuters.
How does AMD’s earnings beat affect Japanese semiconductor stocks?
AMD’s revenue and guidance beats signal accelerating demand for advanced AI chips, which flow upstream into Japan’s semiconductor supply chain. Ibiden makes the IC substrates in every AMD package; Mitsui Kinzoku supplies copper foil for PCBs; Renesas makes microcontrollers used in AI server platforms. When AMD reports a beat of this magnitude, Tokyo’s chip supply chain reprices within the same session; Thursday’s 13–17% gains across those names confirmed that linkage directly.
What is the Bank of Japan’s interest rate outlook after May 7, 2026?
The BoJ’s current policy rate is 0.75%, held steady at both the March 18–19 and April 2026 meetings. March meeting minutes released Thursday showed “many” board members backed further hikes if Middle East-driven energy costs stayed elevated. With crude now softening on Iran deal expectations, that energy-inflation trigger has weakened. The specific signal to track at the May BoJ meeting: if “many members” on energy inflation shifts down to “some members,” it indicates the rate hike timeline is being pushed out.
