Wall Street stocks soared on Wednesday after the Federal Reserve announced a large 50 basis points interest rate increase but ruled out an even bigger hike for the foreseeable future.

The Dow Jones rose 2.8 percent, or more than 930 points, to 34,061.

The S&P 500 gained 3.0 percent to 4,300, while the Nasdaq jumped 3.2 percent to 12,964.

Wednesday's interest rate hike – the biggest since 2000 – was coupled with a move to begin reducing the central bank's bond holdings from June 1, marking the Fed's most aggressive steps so far to counter inflation.

Fed Chair Jerome Powell said 50-basis point increases "should be on the table at the next couple of meetings," but added that a three-quarter point rise increase "is not something the committee is actively considering."

Stocks rallied off the remarks as Powell also expressed confidence the US central bank could engineer a "soft landing" that tames inflation without sending the economy into recession.

Art Hogan, strategist at National Securities, said the Fed's decision met expectations, but contained "no hawkish surprise," adding that stocks could push higher in the coming sessions.

Some analysts have viewed the market as positioned for a potential rally after suffering deep losses in April amid worries over the Fed.

Wednesday's rally was broad-based, with all 11 S&P 500 sectors advancing, along with every company in the Dow.
