Global equity markets closed sharply lower as rising bond yields, inflation concerns, and geopolitical tensions weighed heavily on investor sentiment. The S&P 500, Nasdaq Composite, and Dow Jones all recorded notable declines, with technology and semiconductor stocks leading the broader market weakness amid profit booking and concerns surrounding higher interest rates.

US markets experienced their weakest trading session since March as elevated Treasury yields continued pressuring growth-oriented sectors. The Nasdaq Composite witnessed significant weakness due to sharp declines across major chipmakers and artificial intelligence-linked companies.

The United Kingdom market also traded lower as investors monitored rising global bond yields, inflation risks, and geopolitical developments across the Middle East. Canada’s S&P/TSX Composite Index declined amid weakness across commodity-linked sectors and broader risk-off sentiment.

Asian markets remained under pressure, with Japan’s Nikkei recording sharp losses as rising bond yields and weakness in export-oriented stocks impacted market performance. New Zealand equities also ended lower amid cautious regional sentiment, while Indian markets showed relatively limited downside compared to global peers.

Overall, investor focus remained centred on inflation trends, central bank policy expectations, geopolitical tensions, and ongoing volatility across global bond and commodity markets.

Commodities & Crypto

AssetPrice (US$)Change
Gold4,547.89/oz-2.22%
WTI Crude105.42/bbl+4.20%
Copper6.25/lb-4.81%
Silver77.54/oz-9.12%
Uranium6,344.80-4.80%
Bitcoin78,207.00+0.08%

Commodity markets witnessed heightened volatility overnight as investors reassessed inflation expectations, rising global bond yields, and escalating geopolitical risks. Precious and industrial metals remained under significant pressure, with higher US Treasury yields continuing to reduce the attractiveness of non-yielding assets and triggering broad-based profit booking across the commodity complex.

Gold prices weakened notably as ongoing inflationary pressures strengthened market expectations that interest rates could remain elevated for an extended period. Copper prices also retreated materially amid weaker global risk sentiment and concerns surrounding slowing industrial demand, particularly as investors evaluated the broader macroeconomic outlook and tightening financial conditions. Silver emerged as one of the weakest performers during the session, registering a steep decline. Uranium prices also corrected lower as investors locked in gains following the sector’s recent strong rally, while broader weakness across commodity-linked equities further weighed on sentiment.

In contrast, crude oil prices extended gains, with WTI crude trading firmly above the US$105 per barrel level. Ongoing geopolitical tensions involving Iran, coupled with concerns surrounding potential disruptions to global energy supply flows, continued supporting bullish momentum across energy markets.

Meanwhile, Bitcoin traded relatively stable despite broader market weakness, indicating resilient investor participation within digital assets as selective risk appetite persisted across cryptocurrency markets.

Bond Yields

IndicatorYieldChange
Australia 10-Year Bond Yield5.077%+0.054 bps
Japan 10-Year Bond Yield2.706%+0.075   bps
US 10-Year Bond Yield4.610%+0.011   bps
US 30-Year Bond Yield5.128%+0.115   bps

Global bond yields continued trending higher as investors remained focused on persistent inflationary pressures, resilient economic indicators, and the likelihood of central banks maintaining restrictive monetary policies for an extended period. Elevated sovereign yields across major economies reflected growing concerns that interest rates may remain higher for longer amid ongoing inflation risks and geopolitical uncertainty.

US Treasury yields remained near multi-year highs, with the 10-year yield holding above the 4.6% level, while the 30-year Treasury yield climbed further as markets reassessed long-term inflation and borrowing cost expectations. Higher yields continued weighing on broader equity market sentiment, particularly across growth-oriented and technology sectors.

Australian government bond yields also advanced as investors monitored domestic inflation dynamics and the potential implications of rising global yields on monetary policy expectations. Meanwhile, Japan’s 10-year government bond yield moved higher as markets continued evaluating the Bank of Japan’s gradual policy normalization and changing domestic inflation conditions.

Overall, rising global bond yields remained a key macroeconomic concern for financial markets, with tighter financial conditions and elevated borrowing costs continuing to influence investor positioning across equities, commodities, and currencies.
