Bill Ackman says a more aggressive Fed or market collapse are the only ways to stop this inflation

cnbc.com:

Billionaire hedge fund manager Bill Ackman said raging inflation will only dissipate if the Federal Reserve acts more aggressively or the market sell-off turns into a full-on collapse.

«There is no prospect for a material reduction in inflation unless the Fed aggressively raises rates, or the stock market crashes, catalyzing an economic collapse and demand destruction,» Ackman said in a slew of tweets Tuesday.

The Pershing Square hedge fund manager attributed 2022's market correction to investors' lack of confidence that the central bank could squash a 40-year high in inflation. He said the market turmoil will only end if the Fed «puts a line in the sand» on soaring prices.

«If the Fed doesn't do its job, the market will do the Fed's job, and that is what is happening now,» Ackman added. «The only way to stop today's raging inflation is with aggressive monetary tightening or with a collapse in the economy.»

The market has been in a big rout this year as the Federal Reserve's tightening measures to tame inflation stoked fears of a recession. The central bank raised its benchmark interest rate by half a percentage point earlier this month, the most aggressive step yet. The S&P 500 is down about 18% in 2022, and the equity benchmark briefly dipped into bear market territory last week.

But Ackman believes at this point investors will cheer the Fed raising rates more rapidly because inflation is spiraling out of control.

«Markets will soar once investors can be confident that the days of runaway inflation are over. Let's hope the Fed gets it right,» Ackman said.

The hedge fund manager said the Fed should demonstrate its seriousness by immediately raising rates to neutral and committing to continue to hike borrowing costs
