U.S. stocks ended Wednesday little changed, as major indexes failed to stray frar from the unchanged mark, with investors digesting the impact of two conflicting sets of jobs data and a report that said President-elect Donald Trump was mulling a national economic emergency declaration on inflation.

"Inflation is the wild card in 2025. There are lots of things that potentially have the risk to shift inflation back upward," said Charlie Ripley, senior investment strategist for Allianz Investment Management.

The minutes of the Federal Reserve's Dec. 17-18 meeting showed on Wednesday that officials saw a rising risk that price pressures may remain sticky as policymakers began wrestling with the impact of policies expected from the incoming Trump administration.

Market sentiment was fragile after a CNN report said Trump was mulling building the new tariff program by using the International Economic Emergency Powers Act, which authorizes a president to manage imports during a national emergency.

Benchmark 10-year yields peaked at 4.73%, the highest since April 25, to retreat slightly to 4.681% later in the afternoon.

Ahead of Trump taking office later in the month, concerns about potential surcharges on U.S. trade partners have kept investors on edge as Trump's policies, including mass deportations and tariffs, could stoke inflation pressures.

"If wider tariffs are implemented it could have a short-term impact on inflation," said Thomas Hayes, chairman at Great Hill Capital LLC. "The Fed will sit back and see if he (Trump) does enact punitive tariffs and if he does, how much of that potential inflationary impact will be offset by the cuts in government spending."
