Amid growing recession concerns due to the US-China tariff war, the US will officially enter the earnings season starting with the financial sector tonight. Next week, the Bank of Korea’s Monetary Policy Committee and the European Central Bank (ECB) meetings are expected to take place.

Ji-won Kim, a researcher at KB Securities, said, "The stock market volatility is extreme due to uncertainties related to tariff policies. The peak may have passed, but pains are inevitable during the US-China negotiation process, and the burden from prolonged tariffs will also act as a variable."
