European stocks set for another lower open as tariff uncertainty dents sentiment

Here are the opening calls

Good morning from London, and welcome to CNBC's live blog covering all the action and business news in European financial markets on Tuesday.

Futures data from IG suggest a negative start to the new trading week for European bourses, with London's FTSE 100 seen opening 0.3% lower, France's CAC 40 down 0.3%, Germany's DAX down 0.4%, and Italy's FTSE MIB 0.4% lower.

European bourses have been on edge since U.S. President Donald Trump announced earlier in July that he would impose a 30% tariff on goods imported from the EU starting Aug. 1. The EU said it hopes to strike a trade deal before then but an agreement remains elusive. The bloc's policymakers are reportedly considering retaliatory measures if a deal can't be reached.

U.S. Treasury Secretary Scott Bessent said Monday that implementing high tariff rates on countries starting Aug. 1 “will put more pressure on those countries to come with better agreements.”

Global market action overnight

U.S. stock futures were little changed early Tuesday after the S&P 500 and Nasdaq Composite hit fresh records in Monday's trading session.

The S&P 500 rose about 0.1% and the Nasdaq Composite advanced nearly 0.4% yesterday, with both indexes hitting new all-time intraday highs and closing at records, aided by a pre-earnings jump in Alphabet. The Dow underperformed and ended the day marginally lower.

Meanwhile, Asia-Pacific stocks traded mixed overnight, with Japanese stocks reopening higher after the ruling coalition lost its majority in the upper house over the weekend.
