The council later today is co-chaired by the prime minister and the chancellor and it will be an opportunity for members to share their views on the economy.
The government is also setting up a "better regulation committee", also chaired by Sunak.
Sunak has also rejected calls to extend a temporary cut to taxes on property purchases, known as stamp duty, that is due to expire at the end of March.
But the truth is that no decisions have been taken this far in advance, not least given the amount of uncertainty in the current outlook.
The number of redundancies reached a record high of 370,000 in the August-to-October period, although it decreased in October alone, the Office for National Statistics said.
Sunak will announce extra investment to ease a backlog in the health system, counter a surge in unemployment and build new infrastructure in a one-year Spending Review that he is due to deliver to parliament at around 1230 GMT.
"Having a difficult economy has an impact on both our ability to fund public services like the NHS but also on individual people's long-term health outcomes," Sunak said, according to the newspaper.
The 2 billion pound Kickstart Scheme will enable employers to hire unemployed young people aged 16-24, using government funds to pay them the national minimum wage for 25 hours a week.
Sunak is expected to focus Wednesday’s announcement mostly on countering a jump in unemployment — which the Bank of England has said could soar to 1980s levels of around 10% or more.
