Global financial markets plunged on Monday following US President Donald Trump’s tariffs on imports, sparking fears of a worldwide recession. The Nikkei 225 index in Japan fell 7.8%, while Hong Kong shares plummeted more than 13% in their worst day since the 1997 Asian financial crisis. Other major indexes also suffered significant losses, including Singapore's benchmark index, which dropped 6.8%, South Korea's Kospi, which lost 4.4%, and Australia's S&P/ASX 200, which fell more than six%. European stock futures also pointed to further losses, with Trump refusing to lift the tariffs unless foreign governments pay "a lot of money".

According to Polymarket, the odds of the US plunging into recession this year have spiked to 62% due to President Trump’s latest round of international tariffs. The odds rose from 39% to 49% after the tariff announcement on April 2 and reached a high of 66% on Sunday, indicating a two-thirds chance of an impending recession. The market fears are reminiscent of "Black Monday" in 1987, with investors bracing for another major sell-off.

Conservative icon Dave Portnoy ranted against Donald Trump on a live stream, saying he lost $20 million since trade obstacles were announced and referred to it as "Orange Monday" due to Trump's complexion. He criticized Trump's decision, which he claimed crashed the stock market, and brought up how Trump bragged about his golf game over the weekend.

Keir Starmer vowed that the UK will "shape history" as he promised to support British industries struggling due to Donald Trump’s tariffs. At a Jaguar Land Rover plant in the West Midlands, Starmer relaxed rules on buying hybrid cars by delaying a ban for five years and pledged to reduce "stifling bureaucracy" across other industries. He assured the audience that the government will back them "to the hilt", stating that these are challenging times but he is committed to supporting them.
