Former U.S. President Donald Trump has announced plans for a 'massive tariff hike' on Chinese imports if he is re-elected, causing significant market volatility. The announcement has led to sharp sell-offs in both stock and cryptocurrency markets, as investors brace for renewed U.S.-China trade tensions. The potential tariffs have raised fears of global supply chain disruptions and inflationary pressures, impacting economic growth prospects. In the crypto sector, $200 million in liquidations were reported, while tech and manufacturing stocks also faced heavy losses.
