Market sentiment was hit by a sharp sell-off on Wall Street overnight, as concerns over a potential recession in the United States intensified. President Donald Trump’s cautious stance on recession fears, coupled with escalating tariff disputes, added to the uncertainty. Asian markets followed Wall Street’s negative trend, with the Hang Seng index falling nearly 1 percent and South Korea’s Kospi shedding up to 1.5 percent.
