  • Data this week showed inflation in April was still running hot and may not have peaked.

  • Wall Street watchers like Mohamed El-Erian and Bill Gross say the Fed will need to get tougher on inflation.

  • The Fed's next policy meeting is in June, and could see it raise interest rates sharply.

US inflation is running a lot hotter and through a lot more sectors of the economy than expected and the Federal Reserve is under pressure to try to bring some of those price pressures down before they cause serious harm to the economy.

Data this week showed inflation rose more than expected in April, up 8.3% year-over-year. This was below March's 8.5% increase but above forecasts for a reading of 8.1% and still at 40-year highs.

Stocks and bonds slid and the dollar soared to a 20-year peak, buoyed up by investors seeking juicier returns than they might find elsewhere.

Some market watchers believe there's a case for the Fed to act even tougher on rates, even raising them by three quarters of a point to try to stave off inflation.

Chair Jerome Powell said this week that the central bank can only control the demand side of the equation, not the supply side, which has been a driving factor in the rise in consumer price pressures.

"The question whether we can execute a soft landing or not, it may actually depend on factors that we don't control," Powell told Marketplace in an interview.

The Fed raised interest rates by 50 basis points in May, the biggest increase at one meeting in 22 years to quell inflation. The faster hiking cycle will primarily fight inflation by weakening demand. Powell said further 50-basis points rate hikes would likely follow at the central bank's policy meetings in June and July, he dismissed 75-basis point increases.

Economists like Mohamed El-Erian disagree and called on the Fed to move more aggressively, with Bill Gross and Liz Young saying the Fed would be prompted to do more to control inflation.

Here's what a number of market experts think:

Mohamed El-Erian, chief economic adviser at Allianz

Economist and outspoken Fed critic Mohamed El-Erian has called out the Fed for its slow response to inflation and called on it to do more.

He said the Federal Reserve needs to be blunt about taming rising inflation and must keep options open for larger rate hikes.

"The Fed right now needs to be a little bit more open minded, not try to just give us good news. Be brutally honest," El-Erian said in an interview with CNBC's "Squawk Box" on Wednesday.

"They've got to be more humble. They can't take anything off the table," he said. "You can't say a 75-basis point is off the table."
