Brent crude touches the $100 mark.

On October 1, the situation in the Middle East continued to disrupt the crude oil market. Investors worried that U.S.-Iran negotiations would not quickly reach a peace agreement, and combined with the fact that Saudi Arabia's East-West oil pipeline had not yet returned to full-capacity operation, international oil prices rose significantly during European trading hours, with Brent crude once touching the $100-per-barrel mark intraday, reaching a high of $100.55 per barrel. As of 16:26 Beijing time on October 1, the price of light crude oil futures for November delivery on the New York Mercantile Exchange was reported at $92.36 per barrel, up 2.17%; the price of London Brent crude oil futures for December delivery was reported at $100.10 per barrel, up 2.09%. The rebound in oil prices intensified market concerns about upside inflation risks, and government bond yields in several major economies continued to rise. The 10-year U.S. Treasury yield once touched 5.342% during European trading hours that day, setting a new high since 2002. At the same time, government bond yields in the UK, France, and Germany rose across the board, weighing on risk appetite in stock markets, with Europe's three major stock indexes declining and large banks and retail consumer sectors falling significantly. HSBC Holdings, affiliated with HSBC, fell more than 3%, Standard Chartered fell nearly 3%, BNP Paribas fell more than 2.7%, and Deutsche Bank fell more than 2.6%. As of 16:23 Beijing time on October 1, the UK's FTSE 100 index fell 1.77%, France's CAC 40 index fell 1.56%, and Germany's DAX index fell 1.21%.
