Morning Bid: US earnings to shed light on tariff impact

A look at the day ahead in European and global markets from Rocky Swift

With markets largely inured to an ever-changing tariff picture, the spotlight turns to Wall Street earnings for clues on how the trade drama is affecting corporate bottom lines.

JPMorgan Chase, Wells Fargo and Citigroup are among heavyweights reporting second-quarter results today. 

Profits for S&P 500 companies in the second quarter are expected to rise 5.8%, according to LSEG data, down from a forecast of 10.2% on April 1, before U.S. President Donald Trump launched his trade war.

Investors are also waiting for U.S. consumer price data for June, looking for any sign of price pressure from tariffs or hints on policy moves by the Federal Reserve.

But the main Fed move Trump is gunning for is an early exit by Chairman Jerome Powell, who hasn't given in to the president's wish for "rocket fuel" rate cuts.

Bond markets are on edge about whether an investigation into renovations of the central bank's headquarters will serve as fodder to oust Powell.

Asian shares and Nasdaq futures got a bounce after Nvidia, the $4 trillion behemoth at the forefront of the artificial intelligence investment boom, said it will resume sales of its H20 chips to China.

Nvidia CEO Jensen Huang will attend the opening ceremony of China's international supply chain expo on Wednesday, Chinese state TV said on Tuesday.

Stock futures in Europe and the broader U.S. market pointed to slight gains at their openings.

Key developments that could influence markets on Tuesday:

- Germany's ZEW Economic Sentiment for July

- Euro zone industrial production data for May

- U.S. core consumer price index (CPI) for June

- Canada CPI, housing starts for June

- U.S. earnings: JPMorgan Chase, Wells Fargo, Citigroup, BlackRock
