Chancellor Jeremy Hunt will deliver parts of his medium-term fiscal plan later today, the Treasury has said.
In a statement the Treasury said the chancellor was fast-tracking the plans, which will be released in full on 31 October.
It said it followed conversations with Prime Minister Liz Truss over the weekend and a meeting with the governor of the Bank of England and the head of the Debt Management Office on Sunday night.
Politics latest: More U-turns expected on mini-budget
Ms Truss is facing calls to resign from three Tory MPs following the economic turmoil in the wake of the mini-budget.
Tory MPs Crispin Blunt, Andrew Bridgen and Jamie Wallis have publicly stated they believe she should resign, while Labour leader Sir Keir Starmer has called on Ms Truss to face parliament and accused her of being “in office but not in power”.
The Daily Mail reported that Tory MPs will try to oust Ms Truss later this week, with more than 100 ready to submit letters of no confidence.

Who could replace Liz Truss as prime minister if she is ousted as Tory leader?

Last week Ms Truss sacked her chancellor Kwasi Kwarteng and replaced him with Jeremy Hunt as she ditched a major chunk of the mini-budget.
Mr Hunt has insisted the prime minister is still in charge during media appearances over the weekend, though he said a tough package of tax rises and spending cuts was necessary in order to steady the UK economy.

Sir Keir said Ms Truss’s brief news conference to explain her latest U-turn on Friday “completely failed to answer any of the questions the public has”.
He said: “Mortgages are rising and the cost of living crisis is being felt ever more acutely. The Conservative government is currently the biggest threat to the security and the finances of families across the country.
“That’s why the prime minister must come to parliament on Monday, to explain what she plans to do to turn the situation around.
“If the prime minister won’t take questions from journalists, Liz Truss must at least take them from MPs representing the families whose livelihoods she’s putting at risk.”
Political editor
I was told by a cabinet source Liz Truss had no option but to sack Kwasi Kwarteng because it was made clear to her he’d lost the confidence of markets and her only hope of steadying the ship was removing him.
But what follows from that is obvious: as a second cabinet source put it to me over weekend, what the markets do in the coming few days will be critical for Ms Truss too.
The firewall provided by the chancellor is now burnt through and if there’s no improvement, the signal will be that the problem is her.
Politically the view settling amongst MPs is that it’s simply not sustainable for her to remain as prime minister.
All eyes are now on Sir Graham Brady, the only person who knows when a leadership election has been triggered, to see what he does. Party rules say Ms Truss has a year’s grace, but they can change the rules.
But there’s also a view, shared by some Truss rivals and backers alike, that the PM has bought a bit of time.
As one cabinet minister told me: “Despite the hysteria, the reality is we need to calm down, let Liz decide her new priorities and Jeremy deliver his budget. Nothing will be gained in the next 14 days by more fratricide.”
But the point is, as Conservative Home’s Paul Goodman put it, it’s over for Ms Truss whether she’s pushed out or not.
Her economic project is finished and her authority is gone. And that makes it very hard to see how she can lead the party into a general election.
I’ll be watching the markets and Sir Graham very closely on Monday.
In a sign of divide within the Tory Party, former culture secretary Nadine Dorries criticised her colleagues.
“I cannot imagine there’s one G7 country which thinks we’re worthy of a place at the table,” she tweeted.
“The removal of one electorally successful PM, the disgraceful plotting to remove another by those who didn’t get their way first time round is destabilising our economy and our reputation.”
