Asian Markets Rally on US‑Iran Peace Deal and Record‑High Nikkei

On 15 June 2026 Asian equity markets surged after the United States and Iran announced a preliminary memorandum of understanding to end their conflict and reopen the Strait of Hormuz. The agreement, slated for formal signing by Friday, also set the stage for subsequent talks on Iran’s nuclear programme, with reports that the United States could resume attacks if a nuclear settlement is not reached.

Index Performance

  • The Australian S&P/ASX 200 (AXJO) rose 1.30%, while Japan’s Nikkei 225 (JP225) jumped 5.23% and the TOPIX (TOPX) added 3.62%, both hitting all‑time highs amid a broad rally in technology and non‑technology stocks.
  • South Korea’s KOSPI (KS11) was the strongest performer, climbing 5.48% and nearing a record level.
  • China’s CSI 300 advanced 1.47% and the Shanghai Composite (SSEC) gained 0.92%.
  • Hong Kong’s Hang Seng (HK50) increased 0.45% and Singapore’s Straits Times Index (STI) rose 1.09%.
  • India’s Nifty 50 futures (NSEI) added 1.53%.
  • SpaceX, the rocket company, recorded “stellar gains” in its U.S. market debut, with the ticker ESU26 up 1.1% in Asian trade.

Geopolitical and Commodity Impact

The MOU between the United States and Iran lifted expectations of immediate de‑escalation in the Middle East, prompting oil prices to fall sharply. Lower crude costs are expected to benefit oil‑import‑dependent Asian economies, notably India, Japan and South Korea, which rely heavily on shipments through the Strait of Hormuz.

Central Bank Outlook

The market focus shifted to upcoming monetary‑policy meetings. The Bank of Japan (BOJ) is widely expected to raise its policy rate by 25 basis points at the conclusion of a two‑day meeting on Tuesday, marking the first hike since June and reflecting rising inflationary pressures linked to the Iran conflict. ANZ analysts anticipate a largely hawkish pivot.

The Reserve Bank of Australia (RBA) is projected to keep rates unchanged in its Tuesday meeting, while the Australian ASX 200 rose 1.30% on Monday. The U.S. Federal Reserve is scheduled to meet later in the week, adding further interest‑rate uncertainty.

Summary of Key Figures

  • Nikkei 225: +5.4% (record high)
  • TOPIX: +3.6% (record high)
  • KOSPI: +5.6%
  • CSI 300: +1.3%
  • Shanghai Composite: +0.9%

The rally underscores how geopolitical developments can swiftly translate into equity‑market gains across the region, while central‑bank decisions later this week remain a pivotal source of market direction.
