A new round of pandemic relief checks for Americans will start going out next week, US Treasury Secretary Steven Mnuchin said Monday.

Congress is expected to give final approval to a $900 billion stimulus package later Monday that will include payments of $600 to all Americans.

-People are going to see this money by the beginning of the next week- Mnuchin said on CNBC.

That amounts to "$2,400 for a family of four so much needed relief in just in time for the holidays."

After months of wrangling, US lawmakers on Sunday finally agreed on a deal to help support the pandemic-battered US economy even as a surge in infections has raised new fears about the recovery.

The package also will include a new round of Paycheck Protection Program loans to businesses, as well as aid for schools, child care and rental assistance, and an additional $300 week in aid to unemployed workers.

While the direct payments are only half the amount provided by the $2.2 trillion CARES Act that Congress approved in March, Mnuchin said it is a "very fast way of getting money into the economy."

-It's money that gets recirculated in the economy, so people go out and spend this money and that helps small business- he said.

President-elect Joe Biden has welcomed the agreement but said much more will be needed to support the world's largest economy.

-Immediately, starting in the new year, Congress will need to get to work on support for our Covid-19 plan, for support to struggling families, and investments in jobs and economic recovery- he said in a statement.
