Senate Republicans hope to jam through a coronavirus relief bill but appear divided on whether the Federal Reserve should be pushing more or less money through its emergency lending programs.

As part of its coronavirus relief proposal package, the Senate GOP proposes downsizing the fund given to the Fed and the U.S. Treasury for the purposes of setting up emergency lending programs — from $454 billion to $250 billion.

The bill would also prevent the Fed from making any new loans through its facilities after mid-January 2021, although it could continue to service loans made before that time.

So far, the U.S. Treasury has only used $195 billion of the fund to support the Fed’s special purpose vehicles backstopping markets ranging from corporate debt to municipal bonds.

“It was totally underutilized,” Senator Mike Braun, an Indiana Republican, told Yahoo Finance’s On The Move on Wednesday.

The GOP hopes that cutting the cost of the program will support the $500 billion relief package’s other proposals, which includes smaller supplemental unemployment benefits and an extension of the Paycheck Protection Program.

The bill will need 51 votes for the bill on the Senate floor, where the GOP holds a narrow 53-to-47 majority.

But it is unclear if all Republicans support the specific measure to pull back the Fed’s emergency powers. The Senate Banking Committee’s top Republican, Mike Crapo of Idaho, has clarified that he would like to see the Fed do more with its Main Street Lending Program.

Crapo has urged the Fed and the Treasury to ramp up lending to small- and mid-size businesses, writing to Fed Chairman Jay Powell and Treasury Secretary Steven Mnuchin in late July that they need to “quickly expand” the pipeline of emergency loans.

George Selgin, director of the Cato Institute’s Center for Monetary and Financial Alternatives, said that Senate Republicans are mixing up its message on a policy response.

“Do we want to give these firms more money or not? If people can’t agree on that — that’s a fundamental issue,” Selgin told Yahoo Finance.

Main Street Lending Program

Although the Fed’s emergency lending facilities cover a wide range of financial markets, Congress has been particularly fixated on the Main Street Lending Program.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act birthed the $454 billion appropriation and directed the Fed to set up a program that “supports lending to small and mid-sized businesses.” The Treasury gave the Fed $75 billion to support the loans and after months of figuring out how to establish the facility, the Fed finally unveiled the program — but to little fanfare.
