• Stocks soared Wednesday after Fed Chair Jerome Powell said a 75-basis-point rate hike isn't on the table.
  • The remark followed a half-point hike to a range of 0.75%-1% that marked the biggest increase since 2000.
  • The Fed also detailed plans to shrink its balance sheet, eventually ramping up to a reduction of $95 billion a month.

US stocks soared after Federal Reserve Chairman Jerome Powell said the central bank's half-point rate hike on Wednesday wouldn't be followed by bigger increases in upcoming policy meetings.

"A 75-basis-point increase is not something the committee is actively considering," he said during a briefing.

That came after the Fed met widely held expectations for a 50-basis-point hike that marks the biggest increase since 2000. Benchmark rates will go up to a range of 0.75%-1%, adding to the Fed's quarter-point increase in March that kicked off the first tightening cycle in four years.

The central bank also detailed plans to shrink its balance sheet, eventually ramping up to a reduction of $95 billion a month.
