Chancellor Reeves has revealed she is preparing "specific steps to deal with cost of living issues" in the upcoming financial statement.
Speaking to the BBC, she emphasized that reducing inflation is a joint responsibility of both the government and the Bank of England.
The United Kingdom's inflation rate is expected to be the most elevated among the G7 industrialized countries this calendar year and the following year.
It is understood the administration could intervene to bring down utility costs, such as by reducing the current 5% rate of VAT charged on energy.
A further possibility is to lower some of the government charges presently added to bills.
The government will obtain the latest draft from the official forecaster, the OBR, on the start of the week, which will clarify how much room there is for such actions.
The expectation from the majority of analysts is that the Chancellor will have to declare tax increases or spending cuts in order to meet her self-imposed borrowing rules.
Previously on the same day, estimates suggested there was a £22bn shortfall for the chancellor to address, which is at the lower end of expectations.
"There's a shared responsibility between the central bank and the administration to continue tackling some of the sources of price increases," Reeves told reporters in the US capital, at the conferences of the International Monetary Fund and World Bank.
While a great deal of the focus has been on likely tax rises, the chancellor said the latest data from the fiscal watchdog had not changed her vow to campaign commitments not to increase rates on earnings tax, sales tax or National Insurance.
She attributed an "uncertain global environment" with rising geopolitical and commercial tensions for the fiscal tax moves, probably to be targeted on those "with the broadest shoulders."
Referring to concerns about the United Kingdom's commercial links with the Asian nation she said: "Our national security invariably take priority."
Recent statement by Chinese authorities to increase export controls on critical minerals and other resources that are essential for advanced tech production led American leader the US President to propose an further 100% tariff on goods from China, raising the risk of an all-out commercial conflict between the two largest economies.
The US Treasury Secretary labeled China's action "economic coercion" and "a global supply chain control attempt."
Asked about accepting the US offer to participate in its conflict with the Asian nation, Reeves said she was "very concerned" by China's measures and called on the Beijing authorities "not to put up barriers and restrict access."
She said the action was "harmful for the international commerce and creates additional obstacles."
"I believe there are sectors where we need to confront China, but there are also important opportunities to export to Chinese markets, including banking sector and other sectors of the economic system. We've got to get that balance appropriate."
The chancellor also affirmed she was working with other major economies "regarding our own critical minerals approach, so that we are less reliant."
Reeves also recognized that the cost the NHS spends on pharmaceuticals could go up as a result of ongoing negotiations with the Trump administration and its pharmaceutical firms, in exchange for lower tariffs and funding.
A number of the world's largest pharmaceutical manufacturers have said in recent statements that they are either pausing or canceling projects in the UK, with several attributing the low prices they are receiving.
Last month, the government science advisor said the price the NHS spends on medicines would must increase to prevent companies and drug research funding leaving the United Kingdom.
The Chancellor told the BBC: "It has been observed because of the pricing regime, that drug testing, recent pharmaceuticals have not been provided in the United Kingdom in the manner that they are in other EU nations."
"Our aim is to guarantee that patients receiving treatment from the National Health Service are able to access the top life-saving drugs in the globe. And so we are examining all of that, and... aiming to obtain additional capital into the UK."
