Asian equity markets staged a powerful rally on Tuesday, April 8, 2026, as investors cheered the announcement of a two-week ceasefire between the United States and Iran. The agreement — which includes Iran allowing safe passage through the Strait of Hormuz and Pakistan hosting peace talks — triggered a broad-based risk-on move across the region, sending oil prices into a historic single-day plunge.

South Korea: KOSPI Surges 6.87% — Buy-Side Sidecar Triggered
The KOSPI posted its strongest single-day gain in months, surging 377.56 points to close at 5,872.34 — up a stunning 6.87% from the previous close of 5,494.78. The rally was so intense that the Korea Exchange triggered a buy-side sidecar for the first time in months at market open, temporarily halting program trading as futures soared.
Foreign investors snapped up a net ₩1.5 trillion (approximately $1.0 billion), focusing heavily on semiconductor names, according to Yonhap Infomax.
Key Movers on the KOSPI
| Stock | Close (₩) | % Change |
|---|---|---|
| SK Hynix | 1,033,000 | +12.77% |
| Korean Air | 24,950 | +8.01% |
| Hyundai Motor | 508,000 | +7.40% |
| Samsung Electronics | 210,500 | +7.12% |
| LG Chem | 344,500 | +6.49% |
| Celltrion | 202,000 | +4.28% |
SK Hynix stole the show with a 12.77% surge, reflecting optimism that lower energy costs will compress semiconductor manufacturing expenses. Samsung Electronics also gained 7.12%, buoyed by strong recent earnings. The KOSDAQ tech-heavy index added 5.12% to close at 1,089.85.
The Korean won strengthened sharply to the 1,470-per-dollar range as the ceasefire eased pressure on energy import costs, according to The Hankyoreh. South Korea had earlier moved to reroute tankers via the Red Sea to bypass the Hormuz closure.
Japan: Nikkei 225 Soars 5.39% — Biggest Gain Since Iran Conflict Began
The Nikkei 225 leapt 2,878.86 points to close at 56,308.42, while the broader TOPIX gained 3.32% to 3,775.30. The relief rally was broad-based: all 33 sectors on the Tokyo Stock Exchange closed higher, according to Nikkei Asia.
Japan stands to benefit significantly from the ceasefire given that more than 70% of its imported naphtha comes from the Middle East. Japanese chemical and material makers had seen their profit outlook darken during the conflict, making Tuesday’s oil price crash particularly welcome. The Nikkei Volatility Index dropped 9.21% to 36.09.
Separately, the Tokyo Stock Exchange saw a milestone as its midtier Standard market overtook Prime in total listed firms, signaling structural shifts in Japan’s equity landscape.
China & Hong Kong: Mainland and HK Join the Rally
Chinese markets posted solid gains despite relatively less direct exposure to Middle Eastern oil supply disruptions. The Shanghai Composite rose 2.69% to 3,995.00, while the CSI 300 advanced 3.49% to 4,595.56. The tech-heavy Shenzhen Component outperformed with a 4.79% gain to 14,042.50.
In Hong Kong, the Hang Seng Index climbed 3.09% to 25,893.02 as Alibaba led an AI-driven tech charge, according to the South China Morning Post. Mainland Chinese investors continued to add Hong Kong stocks for a third straight month.
On the regulatory front, CSRC tightened trading scrutiny on major shareholders and executives, introducing new rules to curb short-term trading and boost investor confidence.
Southeast Asia & India: Broad-Based Relief
Southeast Asian markets, which had been among the hardest hit by the Iran conflict due to fuel subsidy pressures, rallied strongly:
- Vietnam VN-Index: +4.71% to 1,756.55 — boosted by FTSE emerging market upgrade expectations
- Indonesia IDX Composite: +4.42% to 7,279.21
- Philippines PSEi: +2.22% to 6,089.91
- Thailand SET: +1.41% to 1,485.03
- Singapore STI: +0.77% to 4,996.05
- Malaysia KLCI: +1.16% to 1,696.31
India’s BSE Sensex surged 3.95% to 77,562.90, while the Nifty 50 gained 3.78% to 23,997.35. The India VIX collapsed 20.89%, reflecting a dramatic reduction in fear.
Pakistan’s Karachi 100 was the day’s top performer globally, rocketing 9.32% to 165,811.02, as Pakistan was named the host of upcoming US-Iran peace negotiations.
Oil Prices: Historic Single-Day Plunge
The ceasefire announcement triggered the largest single-day oil price decline since the conflict began in late March:
| Commodity | Price | Change | % Change |
|---|---|---|---|
| WTI Crude | $95.88 | -$17.07 | -15.11% |
| Brent Crude | $94.75 | -$14.52 | -13.29% |
| Gold | $4,810.90 | +$126.20 | +2.69% |
Sources: Investing.com
WTI crude cratered from a previous close of $112.95 to $95.88, while Brent fell from $109.27 to $94.75. The drop reflects market expectations that Iran will reopen the Strait of Hormuz during the ceasefire, restoring roughly 20% of global oil supply transit. Gold, meanwhile, jumped to a three-week high as investors rotated into safe-haven assets amid ongoing uncertainty about the ceasefire’s durability.
However, late-breaking reports indicate that oil tankers passing through Hormuz have been stopped after Israel’s ceasefire breach, which could reignite volatility in the coming sessions.
US & European Markets: Overnight Context
Wall Street had already rallied overnight on ceasefire anticipation. The S&P 500 gained 2.34% to 6,771.62, the Dow Jones rose 2.73% to 47,855.41, and the Nasdaq advanced 2.78% to 22,630.90. The VIX fear gauge plunged 19.33% to 20.80. European indices were also strong, with the DAX jumping 5.13% and the CAC 40 gaining 4.95%.
What to Watch Next
- Ceasefire durability: Reports of tanker stoppages at Hormuz suggest the truce remains fragile. Any breakdown could reverse today’s risk-on trades sharply.
- Saudi Aramco’s record oil premium: Despite the ceasefire, Aramco has set its highest-ever Asian oil premium for May shipments at $19.50/barrel, signaling that energy costs may remain elevated.
- Central bank responses: The ADB chief noted that Asia can ease war shocks through fiscal and monetary policy.
- Vietnam FTSE upgrade: A decision on elevating Vietnam to emerging market status could unlock billions in passive fund flows.
