Trump started hiking tariffs on Chinese goods shortly after his return to the White House. China ultimately responded with tariffs of its own. Tensions escalated, with tariff rates hitting the triple digits, before a trade truce in May.

Investors hoping for a flurry of trade deals before the Aug. 1 deadline may be underwhelmed at the minute. Talks with China ended in Stockholm yesterday, while a deal with India has yet to be announced. Meanwhile, a clutch of well-known German companies have put figures on how much taxes on imports to the U.S. are costing them.

U.S. and Chinese officials agreed to seek an extension of their 90-day tariff truce on Tuesday, following two days of what both sides described as constructive talks in Stockholm aimed at defusing an escalating trade war between the world's two biggest economies that threatens global growth.
