UK finally shows signs of productivity boost, while analysts say early signs of tech-driven improvements in productivity growth could herald a sustained strengthening in the UK's economic outlook, according to FT

UK productivity commentary of this kind carries a long and well-known history of false dawns: the country's post-crisis productivity stagnation has been repeatedly declared over on the back of a few quarters of stronger output-per-hour, only for revisions or compositional effects to unwind the claim. The distinction worth drawing is between cyclical productivity gains, which appear when output recovers faster than hours worked, and genuine supply-side improvement, which is what determines the sustainable pace of growth and the room the MPC has before wage growth turns inflationary. A tech-driven narrative sits in the harder-to-verify category; diffusion of new technology into measured productivity has historically shown up in the data with a lag of years and unevenly across sectors, so single-period prints are weak evidence. If sustained, the transmission runs through the UK's potential growth estimate, the neutral rate, and by extension the term premium demanded on gilts, rather than through any front-end repricing. What carries signal is the follow-through: revisions to output-per-hour series, business investment intentions, and whether official forecasters begin marking up supply-side assumptions, since that is what changes the fiscal arithmetic the OBR works from. As commentary rather than a release, the read is directional at best.
