Treasury head Reeves has announced she is preparing "specific action to deal with cost of living issues" in the upcoming Budget.
In comments to the BBC, she noted that reducing inflation is a collective duty of both the government and the Bank of England.
The United Kingdom's price growth is projected to be the most elevated among the Group of Seven industrialized countries this year and the following year.
Sources suggest the administration could intervene to bring down energy bills, for instance by slashing the present 5% level of value-added tax applied on energy.
Another approach is to lower some of the government charges currently included in household expenses.
The government will receive the next draft from the official forecaster, the OBR, on the start of the week, which will reveal how much scope there is for these actions.
The view from most experts is that Reeves will have to introduce higher taxes or expenditure reductions in order to adhere to her declared fiscal targets.
Previously on Thursday, calculations suggested there was a £22 billion shortfall for the Treasury chief to address, which is at the more modest range of forecasts.
"There's a shared responsibility between the Bank of England and the government to continue tackling some of the causes of inflation," the Chancellor told reporters in Washington, at the conferences of the International Monetary Fund and World Bank.
While a great deal of the attention has been on expected tax increases, the Treasury chief said the latest information from the OBR had not changed her vow to campaign commitments not to increase tax levels on earnings tax, VAT or social security contributions.
She blamed an "uncertain global environment" with rising geopolitical and commercial tensions for the Budget revenue measures, probably to be focused on those "wealthiest."
Addressing worries about the United Kingdom's economic relations with the Asian nation she said: "The UK's security interests always are paramount."
Recent announcement by China to strengthen trade restrictions on critical minerals and other materials that are crucial for high-technology production led US President the US President to propose an additional 100% import tax on imports from China, increasing the risk of an full-scale trade war between the two largest economies.
The US Treasury Secretary described the Chinese decision "commercial pressure" and "a international production power grab."
Inquired about accepting the American proposal to join its conflict with the Asian nation, Reeves said she was "deeply worried" by China's actions and called on the Beijing authorities "to avoid restrictions and limit trade."
She said the move was "harmful for the global economy and creates additional obstacles."
"I believe there are areas where we need to challenge Chinese policies, but there are also valuable chances to trade with China's economy, including banking sector and other areas of the economic system. We've got to get that balance correct."
The chancellor also stated she was working with other major economies "regarding our own critical minerals approach, so that we are reduced dependence."
The Chancellor also admitted that the cost the NHS spends on medicines could rise as a consequence of current discussions with the Trump administration and its pharmaceutical firms, in exchange for lower tariffs and capital.
Some of the world's largest pharmaceutical manufacturers have said recently that they are either halting or canceling investments in the United Kingdom, with some attributing the modest returns they are getting.
Recently, the Science Minister said the price the health service spends on medicines would need to rise to prevent businesses and pharmaceutical investment leaving the UK.
The Chancellor informed media: "We have seen due to the payment system, that drug testing, new drugs have not been offered in the United Kingdom in the way that they are in other European countries."
"We want to guarantee that patients getting treatment from the NHS are able to obtain the finest critical drugs in the world. And so we are examining these issues, and... aiming to secure more funding into Britain."
