Updates before markets open

Feb 19 (Reuters) - Wall Street's main indexes were set to open flat on Wednesday on worries over proposed U.S. auto tariffs and ahead of minutes from the Federal Reserve's January meeting, while electric-truck maker Nikola tumbled after going bankrupt.

Trump said on Tuesday that he intended to impose auto tariffs "in the neighborhood of 25%", along with similar duties on semiconductor and pharmaceuticals imports.

Trump's tariffs have raised concerns if they would fuel inflation in the U.S. and weigh on the Fed's stance on rate cuts this year.

Minutes of the U.S. central bank's January policy meeting - where voting members elected to let interest rates stand and Fed Chair Jerome Powell said there would be no rush to cut them again until inflation and jobs data made it appropriate - are scheduled to be released at 2 p.m. ET.

"With the risk of inflation moving higher as well as where financial conditions are, the Fed is really not in a hurry to cut rates," said Charlie Ripley, senior investment strategist for Allianz Investment Management.

Investors will look for hints on the Fed's rate plans for the year in the minutes, in light of last week's mixed consumer and producer prices data coupled with a sharp drop in retail sales, which had sent Treasury yields lower.

Traders currently see at least one 25-basis-point rate cut and a 44% chance of an additional lowering by December, according to LSEG data.

Since his inauguration in January, Trump has imposed a 10% tariff on all imports from China, on top of existing levies. He also announced and delayed for a month 25% tariffs on goods from Mexico and non-energy imports from Canada.

"Talking about tariffs is not the same as implementing tariffs, and I think we've seen a lot of talk over the past month or so and not a lot on the implementation side of things," Ripley said.

The S&P 500 .SPX eked out an all-time closing high in the last session, lifting tech heavyweights Microsoft MSFT.O and Nvidia NVDA.O.
