“The OBR is far from perfect,” Jenrick is expected to say, in a speech in the City of London.
“But the impetus for its creation was a desire to instill fiscal discipline, and that is something we wholeheartedly endorse.”
With Reform UK consistently leading in national opinion polls, the party’s economic plans are coming under greater scrutiny.
In November, Farage rowed back on Reform’s previous promise to deliver tax cuts worth £90bn a year, as he sought to strengthen the party’s credibility on economic policy.
Jenrick’s speech is the latest attempt to signal the party can be trusted to manage the public finances.
The OBR assesses the health of the UK’s economy and the government’s spending plans.
It is independent of the government and its reports are usually released alongside big financial events such as the budget in the autumn.
However, some have questioned whether the body has too much power, given the level of influence its forecasts have over the government’s economic policy.
Among the OBR’s critics is Reform UK deputy leader Richard Tice, who last month told Politico, external the budget watchdog was “literally telling the government how to run its policy”.
But in a change of tone, Jenrick is expected to say his party would be “happy to have our homework marked” by the OBR.
“Rather than abolish it, we will reform it,” Jenrick is set to say.
“We will break up this cosy consensus and ensure it has diversity of opinion.
“And we’ll run competitions for superforecasters to join the body and pay competitive salaries to those who most accurately model the impact of Treasury decisions.”
