The trade truce is off and has sent markets reeling. Squawk Box anchors digest the massive moves across asset classes after U.S. President Donald Trump loses patience with a lack of progress on trade talks with Beijing and slaps 10 per cent onto $300bn of Chinese goods.

Elsewhere, U.K. Prime minister Boris Johnson’s majority in the House of Commons shrinks following a by-election in Wales. On the corporate front, we break earnings from Credit Agricole and Allianz.
