Asian Markets Tumble as US-Iran Fighting Lifts Oil, Yields
Stock markets in Asia fell because investors became worried about a conflict between the United States and Iran.
The fighting pushed oil prices higher.
More expensive oil can make many goods and services cost more.
Investors feared that rising prices could lead central banks to keep interest rates high or raise them.
Higher interest rates can make it more expensive for companies and people to borrow money.
Bond yields also rose sharply around the world.
South Korea’s KOSPI and Japan’s Nikkei were among the biggest decliners.
US stocks had also fallen for a third straight session.
India’s markets were expected to open weak, although strong domestic growth could provide some support.
Asian stocks fell on September 2 as higher oil prices and bond yields raised inflation concerns.
The MSCI Asia-Pacific index declined about 0.8% to 1%, while South Korea’s KOSPI fell roughly 3% at the open.
Japan’s Nikkei 225 dropped between 1.6% and 2.2%, while Australia’s S&P/ASX 200 lost 1.09%.
Brent crude rose toward $95 a barrel amid fears that fighting could disrupt shipments through the Strait of Hormuz.
Investors increased bets on a Federal Reserve rate hike, while US stocks extended their declines overnight.
