As the Federal Reserve is preparing to issue new $75 billion of bonds, many economists believe the central bank will stop issuing its benchmark $1.20 trillion of bonds in the coming months.

It’s possible that the Fed could issue a smaller amount of bonds with interest rates below the benchmark rate, according to people familiar with the matter.

The Fed has not indicated that it is considering that option, and many investors have expressed concern that the central banks future decisions could affect them and their portfolios.

The Fed has issued nearly $1 trillion of debt in the past three months, most of it to banks and other financial institutions.

The central bank is expected to issue another $1 billion of debt on Tuesday.

The Fed, which is in its sixth month of bond-buying programs, said it is making progress on its plan to print $1,000 trillion of new bonds, with the latest issuance of about $40 billion of those bonds.

“There’s still a lot of slack in the economy, but there’s certainly enough slack that we think it’s time to ramp up our economic growth,” Mnuchin told CNBC’s “Squawk Box.”

“I think the U
