• U.S. stock futures rose Monday, as investors digest tariffs, inflation and earnings.
• President Donald Trump said he would impose 25% duties on steel and aluminum imports.
• McDonald's posted slightly worse than expected sales in its fourth quarter.

Here are the most important news items that investors need to start their trading day:

1. A bumpy ride

Stock futures climbed Monday as investors digested the latest phase in a brewing global trade war. The three major U.S. averages dipped last week. The S&P 500 slipped by 0.2%, while the Dow Jones Industrial Average and Nasdaq Composite both slid by 0.5%. Inflation, interest rates and the potential for tariffs to increase prices will be in focus this week. The consumer price index is due Wednesday, while the producer price index is set for Thursday. A handful of major companies will also report earnings, offering a read on consumer spending and how tariffs could affect their businesses. Follow live market updates.

2. The art of the steel

President Donald Trump escalated his global trade conflicts on Sunday, saying he would impose 25% tariffs on steel and aluminum. He did not say when he could impose the duties. While the duties could help U.S. metals companies like U.S. Steel and Nucor, they could also raise prices of some items for U.S. consumers and open up other products to retaliatory tariffs. The tariffs on metals were not the only major change the Trump administration was putting into motion over the weekend. Consumer Financial Protection Bureau employees were told to work remotely, shortly after acting CFPB Director Russell Vought told staff to suspend nearly all of the regulator's activities. Democratic lawmakers and consumer advocates slammed the move, saying it could expose Americans to predatory practices by lenders.

3. McDonald's underwhelms

McDonald's posted slightly worse-than-expected sales in its fourth quarter, as an E. coli outbreak linked to its Quarter Pounder burgers hit its U.S. business. The company's worldwide same-store sales climbed 0.4%, compared to the 1% decline Wall Street expected. But the burger giant's U.S. business performed worse than expected: same-store sales fell 1.4%, compared with Wall Street's estimate of a 0.6% drop. Traffic improved during the quarter, but customers spent slightly less than usual, as the chain relied on value meals to draw diners.

4. A flurry of earnings

McDonald's isn't the only massive company set to post results this week. Coca-Cola, CVS and Biogen are among the businesses reporting earnings. Here are they key results to watch:

• Tuesday: Coca-Cola (before the bell)
• Wednesday: CVS, Biogen, Restaurant Brands International (before the bell); Cisco, Reddit (after the bell)
• Thursday: Airbnb, Coinbase (after the bell)
• Friday: Moderna (before the bell)

5. Bird is the word

The Philadelphia Eagles routed the Kansas City Chiefs in Super Bowl LIX. In a game that was expected to be close, the Eagles dominated on both sides of the ball on the way to a 40-22 victory. It was Philadelphia's second Super Bowl and denied Kansas City the first three-peat in Super Bowl history.
