The biggest Fed rate hike in 40 years? It could be coming next week.

Desperate times call for desperate measures, and times are, arguably, increasingly desperate. The persistence of high inflation might force the Federal Reserve to resort to the biggest increase in a key U.S. interest rate in more than 40 years.

After another dismal U.S. inflation report, economists at the brokerage Nomura Securities on Tuesday became the first on Wall Street DJIA, -0.45% to predict a full-percentage-point increase in the Fed’s benchmark short-term rate.

“We continue to believe markets underappreciate just how entrenched U.S. inflation has become and the magnitude of response that will likely be required from the Fed to dislodge it,” the economists at Nomura wrote in a report to clients.
