Global equity markets traded mostly higher overnight as easing bond yields, declining crude oil prices, and optimism surrounding progress in US-Iran negotiations improved broader investor sentiment. US markets delivered strong gains, with the S&P 500 snapping its recent losing streak while the Nasdaq Composite outperformed following renewed strength across technology and artificial intelligence-linked stocks. The Dow Jones Index also advanced firmly, reclaiming the 50,000 level amid broad-based buying across industrial and financial sectors.

Investor confidence improved after softer Treasury yields reduced immediate pressure on growth-oriented valuations. Nvidia remained a key market focus after reporting stronger-than-expected quarterly earnings and issuing upbeat forward guidance, which supported sentiment across semiconductor and technology sectors.

The United Kingdom also closed higher overnight, supported by gains across industrial, financial, and commodity-linked sectors as investors responded positively to easing geopolitical concerns and improving global risk appetite. Meanwhile, Canada’s S&P/TSX Composite Index advanced during the session, driven by strength across materials and financial stocks amid improving broader market sentiment.

Asian markets delivered mixed performance during the session, with Japan’s Nikkei Index declining amid caution surrounding export-oriented sectors. Indian equities, however, remained relatively resilient, supported by selective buying across domestic-facing sectors and stable investor sentiment. New Zealand equities underperformed during the session, with the NZX 50 declining as weakness across consumer-linked sectors weighed on broader market sentiment.

Overall, global markets witnessed improved sentiment overnight as easing bond yields, lower crude oil prices, and optimism surrounding US-Iran negotiations supported broader risk appetite.

US 10-Year Bond Yield4.595%+0.020 bps

Key Drivers

  • Optimism surrounding ongoing US-Iran negotiations improved global market sentiment and triggered a sharp decline in crude oil prices amid easing concerns regarding potential supply disruptions. 
  • US Treasury yields moderated from recent multi-year highs, providing temporary relief for growth-oriented sectors, particularly technology and semiconductor stocks. 
  • Nvidia’s stronger-than-expected quarterly earnings, robust AI-driven revenue growth, and upgraded forward guidance significantly boosted sentiment across global technology markets. 
  • The sharp pullback in oil prices improved inflation expectations and reduced immediate concerns surrounding additional pressure on global central bank policy tightening. 
  • Elevated global bond yields continued remaining a key medium-term risk factor for equity markets despite the overnight easing in fixed-income markets. 
  • Strong performance across commodity-linked sectors, including copper, silver, and strategic metals, highlighted improving sentiment toward industrial and infrastructure-driven demand themes.
