A government plan to help support people with the rising cost of living could come as soon as Thursday, the BBC understands.
The PM and chancellor have been under growing pressure to act as prices for fuel, food and energy continue to soar.
But BBC political editor Chris Mason said the government was also desperate to shift the agenda on from Partygate.
Downing Street denied the announcement was timed to distract from Sue Gray's report into lockdown gatherings.
The senior civil servant's report into events held in Downing Street is expected to be sent to No 10 on Wednesday.
The Prime Minister is to meet Chancellor Rishi Sunak soon to finalise plans, with an announcement possible on Thursday.
Mr Johnson has in recent days invited a collection of economists with a range of views to explore the options available to him, the BBC understands.
Sources told the BBC that Mr Johnson spoke on Tuesday about the need to balance any further government spending and intervention with not "raising inflation" further.
It is also understood Policing Minister Kit Malthouse repeated calls at cabinet to swiftly return to a "low tax" society.
Last week, inflation reached a 40-year high and on Tuesday the energy regulator Ofgem warned the energy price cap - which limits how much providers can raise prices - is expected to increase to £2,800 a year in the autumn.
Opposition parties have continued to push for a windfall tax on oil and gas firms - a one-off levy on the record profits the companies have recorded - saying the proceeds could be used to support the hardest hit.
But while attitudes towards the idea in government appear to have softened, neither Mr Johnson nor Mr Sunak have committed to the move.
Rishi Sunak has long argued - privately and publicly - that help for the most vulnerable could only be properly designed once the scale of the problem was measurable.
Tuesday's intervention from Ofgem provides that.
The question now is precisely what help is offered, and at what cost.
Targeted possibilities include uprating benefits or a lump sum payment to some of the poorest households.
There is then the quandary of whether to offer something that a greater proportion of people benefit from - could the first £40 repayment of the government's Energy Bills Support Scheme be postponed or cancelled?
Other options in the months ahead include changes to the Warm Homes Discount and the Winter Fuel Payment.
But any combination of these possibilities could easily be way more costly than the revenue generated from any windfall tax on the oil and gas companies.
An intervention that is noticeable won't come cheap.
A number of ministers have also raised concerns about the idea of a windfall tax, with Mr Johnson saying he was not "attracted" to the measure in principle.
But he told reporters "no option is off the table" to tackle rising living costs, adding: "There is more that we are going to do... you'll just have to wait a little bit longer."
Labour leader Sir Keir Starmer has called on the government to "get a grip" and introduce the levy.
