Japan’s Nikkei 225 index closed at a record 69,317.50 on Monday, up 4.99% after the US and Iran announced a framework to end their conflict. The deal includes reopening the Strait of Hormuz, a critical oil shipping route. Oil prices fell 4.5% to below $83.40 per barrel. Investors expect lower energy costs and improved corporate earnings as global supply chains normalize.
Record Close Driven by Peace Deal Relief
The Nikkei 225 surged 3,297.46 points to finish above 69,000 for the first time ever. The broader TOPIX index also hit a record, climbing 117.64 points to 3,999.60. Investors rushed to buy stocks across all sectors after US President Donald Trump announced the deal on Sunday, with the index posting its second-largest daily point gain on record.
Oil Collapse Eases Inflation Pressure
Brent crude dropped 4.5% to $82.84 per barrel as markets priced in the reopening of the Strait of Hormuz, through which 20% of the world’s oil and liquefied natural gas normally flows. The waterway has been effectively closed since late February. Lower oil prices provide relief for central banks worried about inflation, according to ANZ’s Asia research head.
Asia Outpaces Global Markets
South Korea’s Kospi jumped 5.7%, while Taiwan’s Taiex climbed 2.7% and Australia’s ASX200 rose 1.5%. Hong Kong’s Hang Seng gained 1% before giving up most gains. US stock futures also climbed, with the S&P 500 up 1% and the Nasdaq Composite up 1.8%. Asia benefited most from the deal because the region relies heavily on Middle Eastern oil and LNG supplies.
Earnings Outlook Improves on Normalization
A Japanese securities firm official stated that the global economy and corporate earnings will likely improve if crude oil supply returns to normal. Pakistan said an official signing ceremony would be held on Friday, June 19 in Switzerland. However, energy experts warned that shipping and insurance companies will need confidence the pact holds before oil prices fully stabilize.
Final Thoughts
The Nikkei 225’s record close reflects investor relief over lower oil prices and reduced Middle East uncertainty. With the index up nearly 5% and crude down 4.5%, the data suggests sustained strength for Asian equities if the peace deal holds through the June 19 signing.
