What happened that day?

  • On 8 April 2026 the Nikkei 225 rose 5.39%
  • The day before, word came that the US had agreed a ceasefire with Iran
  • Japan reacts especially strongly to this because of energy — it imports nearly all the oil it burns
  • When war-driven oil prices fall, company costs fall and the trade balance improves with them
  • The index had been 13.23% below its peak in this stretch. The further it had been pressed, the bigger the bounce
  • This ceasefire was not the end of the war. The final deal came two months later, in June
  • On that June news the Nikkei passed 69,000 for the first time
