The stock market is demanding the Fed take historic action on inflation

The stock market won’t be satisfied unless the Federal Reserve takes drastic action on inflation.

Investors now overwhelmingly predict the Fed will raise rates by a remarkable three-quarters of a percentage point at the conclusion of its policy meeting Wednesday. That hasn’t happened since 1994, when Alan Greenspan ran the Fed.

After raising rates by a half point in May — an action the Fed hadn’t taken since 2000 — Chair Jerome Powell pledged more of the same until the central bank was satisfied that inflation was under control. At that point, the Fed would resume standard quarter-point hikes, he said.

But after May’s hotter-than-expected inflation report, Wall Street is increasingly calling for tougher action from the Fed to keep prices under control. Goldman Sachs on Tuesday joined Jefferies and Barclays in predicting that the Fed would hike rates by three quarters of a point, also referred to as 75 basis points, this week.

There may have been some so-called Fed whispering taking place this week, too: The Wall Street Journal reported Monday the Fed would consider a larger-than-ancipated hike in its policy meeting this week.

“Definitely, we’re going to see 75 basis points after this meeting,” Bill Dudley, the former president of the New York Federal Reserve Bank, told CNN. “I think they wanted to make sure that they were not following farther behind the curve, so they had some conversations with some key journalists.”

Traders have gotten the message: The stock market has priced in a 95% chance that the central bank will raise rates by three quarters of a point, according to Fed funds futures listed on the CME. That marks a stunning change in sentiment from Monday, when just 40% of investors believed the Fed would raise rates that high. A week ago, expectations for a three-quarter-point increase were just 3%.

“The big surprise now would be if they went back to 50 basis points,” Dudley said.

Not only is Wall Street convinced that the Fed will take more severe action against inflation Wednesday, it also believes that it will raise rates by another three-quarters of a point in July. Nearly 90% of investors believe the Fed will hike rates by that same amount next month, following similar expectations from Goldman, Jefferies and Barclays.

Such strong medicine for inflation could pose a threat to the US economy, however. In a note to clients Tuesday, Goldman analysts warned tightening financial conditions could further drag growth “somewhat beyond” what the Fed “should be targeting to have the best chance of bringing down inflation without a recession.”

That could make the elusive “soft-landing” that Powell has aimed for all but impossible to achieve. When the Fed raises rates, it almost always crash-lands the economy into a recession. But there have been rare instances when the Fed has cooled off the economy and kept prices in check without sending the US economy spiraling into a downturn: Once in 1965, and again in 1984 and 1994.

A growing chorus of analysts, including Dudley, believe the Fed acted too late on inflation to avoid such a soft landing. Regardless, a failure to act fast on inflation could have devastating consequences for the economy, too.
