Treasury head Reeves has announced she is planning "specific measures to tackle household expense issues" in next month's Budget.
During an interview with media outlets, she stated that curbing inflation is a joint responsibility of both the government and the Bank of England.
The UK's price growth is projected to be the highest among the G7 developed nations this year and the following year.
Sources suggest the administration could intervene to lower utility costs, for instance by reducing the current 5% level of value-added tax charged on energy supplies.
An additional approach is to lower some of the policy costs presently included in household expenses.
The administration will obtain the latest assessment from the independent fiscal watchdog, the OBR, on the start of the week, which will clarify how much room there is for such measures.
The view from most experts is that Reeves will have to announce tax rises or spending cuts in order to fulfill her voluntary fiscal targets.
Earlier on Thursday, estimates suggested there was a £22 billion gap for the Treasury chief to address, which is at the lower end of forecasts.
"There's a joint responsibility between the central bank and the government to bear down further on some of the causes of inflation," Reeves told the BBC in Washington, at the conferences of the International Monetary Fund and global financial institution.
While a great deal of the focus has been on likely tax increases, the chancellor said the latest figures from the fiscal watchdog had not changed her pledge to campaign commitments not to raise tax levels on income tax, VAT or National Insurance.
She blamed an "unpredictable world" with rising geopolitical and trade tensions for the Budget tax moves, probably to be targeted on those "most able to pay."
Addressing concerns about the United Kingdom's commercial links with the Asian nation she said: "Our national security always take priority."
Recent declaration by China to tighten trade restrictions on critical minerals and other materials that are crucial for advanced tech manufacturing led American leader the US President to threaten an additional 100% tariff on imports from the Asian country, increasing the risk of an full-scale trade war between the two global powers.
The US Treasury Secretary labeled the Chinese decision "commercial pressure" and "a international production power grab."
Inquired about accepting the US offer to join its dispute with China, the Chancellor said she was "very concerned" by Chinese measures and called on the Beijing authorities "not to put up barriers and restrict access."
She said the move was "bad for the international commerce and causes further obstacles."
"It is my opinion there are fields where we should challenge Chinese policies, but there are also important chances to export to Chinese markets, including banking sector and other sectors of the economy. We've got to maintain that balance right."
The Treasury chief also stated she was collaborating with international partners "regarding our own critical minerals plan, so that we are less reliant."
The Chancellor also recognized that the cost the NHS spends on drugs could increase as a consequence of ongoing negotiations with the US government and its drugs companies, in exchange for reduced taxes and capital.
Some of the biggest global pharmaceutical manufacturers have said in recent statements that they are either pausing or scrapping operations in the United Kingdom, with some blaming the insufficient payments they are obtaining.
Last month, the Science Minister said the price the health service spends on drugs would have to go up to stop businesses and drug research funding leaving the United Kingdom.
Reeves informed the BBC: "It has been observed because of the payment system, that clinical trials, recent pharmaceuticals have not been offered in the United Kingdom in the extent that they are in other EU nations."
"We want to make sure that patients getting treatment from the NHS are able to access the finest essential drugs in the world. And so we are looking at these issues, and... aiming to attract increased investment into Britain."
