The Fed publishes its quarterly economic forecast, the so-called dot plot, together with the interest rate declaration at 2 p.m. ET Wednesday. Powell will hold a press conference afterwards.
"We need to see evidence that the Fed's dot plots aren't coming out in a way that scares the market, ”said Yung-Yu Ma, chief investment strategist at BMO Wealth Management.
The weakness in the Chinese stock market was reflected in US stocks on Monday. The benchmark Hang Seng index plummeted 4% as ailing real estate developer China Evergrande Group was on the verge of default.

September is a historically volatile month for stocks and after the S&P 500 rallied 16% since the start of the year, many investors have said the market is due to pull back. Some strategists called the sale on Monday a buying opportunity.
"The market sell-off that escalated overnight is, in our opinion, mainly driven by technical sales flows ((commodity trading advisors) and option hedgers) in an environment of low liquidity and the overreaction of discretionary traders to perceived risks," said Marko Kolanovic, JPMorgan chief global market strategist. said in a note on Monday.
While others said the volatility is likely to continue until some of the risks are addressed.
"We don't think this small pullback is a special buying opportunity," said Ma. "There could easily be more volatility depending on what happens to the Fed meeting … similar to the debt ceiling. With the overhang and negotiations that follow, this will definitely be taken to extremes."
Cryptocurrencies also pulled back on Monday, with Bitcoin ending the day about 7% lower. The slide sparked the debate about whether Bitcoin can or should serve as a safe haven.
