U.S. stock index futures traded mostly higher Tuesday, with investors digesting quarterly earnings from a number of major bank earnings as well key consumer inflation data. 
At 08:45 ET (12:45 GMT), Dow Jones Futures fell 35 points, or 0.1%, while S&P 500 Futures rose 24 points, or 0.4%, and Nasdaq 100 Futures gained 150 points, or 0.7%. 
The main averages on Wall Street ticked up in the prior session, as a slate of artificial intelligence-related headlines helped to soothe worries over fresh U.S. threats of punishing tariffs on Europe and Mexico.
U.S. CPI offers mixed picture
U.S. consumer prices grew at a faster-than-anticipated annualized pace in June, with the Labor Department’s headline consumer price index coming in at 2.7% in the twelve months to June, compared with expectations of 2.6% and May’s reading of 2.4%.
Month-on-month, the figure was 0.3%, up from 0.1% in May and in line with projections.
However, the data release had more positive news on an underlying basis, as the so-called "core" CPI, which strips out volatile items like food and fuel, grew 2.9% year-over-year, below the 3.0% expected, and 0.2% on a monthly basis, again below the 0.2% forecast.
The Federal Reserve has warned of the effects of Trump’s tariffs on domestic prices, with sticky inflation likely to keep the central bank from cutting interest rates in the near-term. 
Banks lead second-quarter earnings season
In the corporate sector, investors are wading through earnings from a host of big U.S. lenders.
These quarterly reports could provide a glimpse into how companies see returns evolving in the coming months against a backdrop of rising international trade tensions. 
JPMorgan Chase (NYSE:JPM) stock slipped slightly premarket after the banking giant’s quarterly profit fell, reflecting a difficult comparison to last year when the bank had recorded a one-time accounting gain, even as trading revenue soared in the quarter as investors seized opportunities and hedged risks in response to shifting U.S. tariff policies. 
Wells Fargo (NYSE:WFC) stock fell after the lender cut its expectation for annual interest income, while BlackRock (NYSE:BLK) dropped despite the world’s largest asset manager’s assets under management rising to a record $12.53 trillion in the quarter.
Bank of America (NYSE:BAC) and Goldman Sachs (NYSE:GS) will report on Wednesday. 
Other Wall Street majors, including Microsoft (NASDAQ:MSFT), Johnson & Johnson (NYSE:JNJ), United Airlines (NASDAQ:UAL), Netflix (NASDAQ:NFLX), American Express (NYSE:AXP), and 3M Company (NYSE:MMM) are also set to report earnings this week. 
Elsewhere, Nvidia (NASDAQ:NVDA) will also be on the spotlight after the AI leader said it will resume the sales of its H20 chip in China, and also announced a new graphical processing unit for Chinese markets.
The move comes as CEO Jensen Huang visits China after recently meeting with top U.S. officials, and follows an improvement in U.S.-China trade relations, after Washington recently lifted several chip technology export restrictions against China. 
Crude stabilizes
Oil prices stabilized after falling late Monday as Trump’s announced a 50-day deadline for Russia to end the Ukraine war and avoid sanctions, easing immediate supply concerns.
At 08:45 ET, Brent futures climbed 0.2% to $69.32 a barrel, and U.S. West Texas Intermediate crude futures rose 0.1% to $67.02 a barrel.
Oil prices had climbed at the end of last week on speculation that the U.S. president was set to impose steep tariffs on Russia, having expressed frustration with Russian President Vladimir Putin due to the lack of progress in ending the war in Ukraine.
However, his milder stance has eased fears of an immediate supply crunch, resulting in selling late Monday.
