US president Donald Trump has unleashed chaos in markets by announcing sweeping “Liberation Day” tariffs. The S&P 500 has shed more than 10% since tariffs were announced, and is expected to plunge further when markets open today (Monday, 7 April).

Asian markets experienced a bloodbath during trading hours on Monday, with the Hang Seng plunging more than 13%, the Shanghai Composite more than 7%, and the Taiex almost 10%. European markets followed suit, selling off dramatically at market open.
