Wall Street continued to be weighed down by a series of downbeat comments from heads of big Wall Street banks over the health of the U.S. economy, raising concerns over the long-term impact of inflation and climbing interest rates on consumers.

Goldman Sachs (GS  ) CEO David Solomon said Wednesday in an interview at the Wall Street Journal's CEO Council Summit that the bank projects stock will fall lower in 2023, with the probability that the Federal Reserve will be able to execute a "soft landing" for the economy standing at only 35%.

"There's a very reasonable possibility that we could have a recession of some kind," Solomon said.

Separately, National Economic Council Director Brian Deese said Wednesday that the U.S. economy is slowing, but is showing "continued resilience" that will position the U.S. to become a center of "investment, productivity and innovation," over the next few years.

"We were out in (Phoenix) yesterday with a set of CEOs who all understand this, that even as we're looking at this transition and navigating through this historically unique transition, the United States looks better as a prospect to invest, and that's going to be a driver," Deese told CNBC's "Squawk Box" in an interview.

Elsewhere, Morgan Stanley (MS  ) analysts reduced their Apple (AAPL  ) iPhone shipment forecast for the December quarter by an additional 3 million units Wednesday, citing slower production in China. The firm now expects Apple to ship about 75.5 million units, down from its original forecast of 85 million units.

Investors are gearing up for more economic data this week ahead of the Federal Reserve's final policy meeting for the year next week. Readings include weekly jobless claims, producer price inflation and preliminary consumer sentiment data for December.
