Resolution Foundation on a changed picture of UK productivity growth
Markdown · JSON · Original source
Resolution Foundation’s piece was published on September 25, 2026. It says the ONS had overestimated working hours, changing the picture of UK productivity growth: the post-financial-crisis slump now looks less steep, and the OBR’s medium-term assumption sits below the revised trend. The Foundation says this changes how recent economic history looks, but cautions against treating it as straightforward good news for public finances. It says the OBR may not have had the data in for the Budget, may not change its assumption, and could interpret the revision as support for its earlier optimism. The Foundation also notes that if UK workers are more productive but work fewer hours, the effects on public finances could offset each other. Its conclusion is that the revised forecast is not wildly out of line with recent trends, a position it says had been absent for a long time. Whether the OBR will revise its assumption, and how working hours affect the fiscal picture, remain unknown.

Open question
Will the Office for Budget Responsibility revise its medium-term productivity assumption in light of the working-hours data, and how will changes in hours worked affect the public finances?
Source-stated
Resolution Foundation says the ONS had overestimated working hours, changing the picture of UK productivity growth since the financial crisis.
The ONS has been overestimating working hours, meaning our average growth in output per hour (a crucial productivity measure) wasn’t actually lower than other countries since the financial crisis.
Source-stated
Resolution Foundation says the revised data makes the post-crisis productivity slump look less steep and places the OBR’s medium-term assumption below the revised trend.
The second row of dots shows where we stand now. Suddenly, the post-crisis slump looks far less steep, with the OBR’s medium-term assumption now below that trend.
Source-stated
Resolution Foundation cautions that the OBR may not have had the data in time for the Budget and may not revise its assumption.
First, it’s unlikely the OBR received this data in time to consider it at the Budget. Second, there’s no guarantee they’ll shift their assumption
Source-stated
Resolution Foundation says lower working hours could offset the public-finance effect of higher productivity.
If UK workers are more productive but also working less there’s a risk it could all come out in the wash.
Source-stated
Resolution Foundation concludes that the revised forecast is now closer to recent trends than it had been for a long time.
Still, we now have a forecast for the public finances which isn’t wildly out of whack with recent trends – which is not a position we have been in for a long time.

attribution — pass: The source is one newsletter issue in which Ruth, Chief Executive of the Resolution Foundation, comments on several items in her own words. The reading attributes the productivity argument to the Resolution Foundation, which matches the Chart of the week section.
Ruth Chief Executive Resolution Foundation
summary — uncertain: The central actors ONS and OBR appear only as acronyms. They are not expanded or explained in the summary, and the definitions list is empty, so a general reader may not know who they are or why the OBR's assumption matters for the Budget. The reading also drops the source's headline point that UK productivity growth per hour was not actually lower than other countries' after the financial crisis. Smallest repair: name and briefly gloss ONS (the statistics office) and OBR (the fiscal forecaster), and restore the cross-country comparison.
wasn’t actually lower than other countries since the financial crisis
date — pass: The reading's September 25, 2026 matches the UTC day of originalPublished. The page was edited after publication (Last-Modified October 23, 2026). The cited Chart of the week text is the titular content and plainly part of the original issue. The source's relative 'two weeks ago' is not repeated as a date. Nothing later is presented as known.
support — uncertain: The summary and claim 5 call it the 'revised forecast'. The source says the existing forecast is no longer out of line because the historical trend was revised, not that the forecast itself was revised. Smallest repair: say the OBR's existing forecast now looks closer to the revised recent trend. Other claims match their excerpts. The cited text appears original despite the later page edit.
Still, we now have a forecast for the public finances which isn’t wildly out of whack with recent trends
media — pass: No media was selected, and no verified candidates were supplied.
