The cost of UK borrowing rose sharply by 0.14% at one point last week after Chancellor Reeves reportedly did a U-turn on raising income tax at the Budget. Although unpopular with the electorate, the rising cost signalled that bondholders would prefer policymakers to raise tax revenues to shore up public finances and avoid borrowing yet more to fund public services. The yield on 10-year gilts topped 4.58%. Tax and growth have a tricky relationship: a funding shortfall plugged by tax hikes may lead to weaker growth, in turn creating a further shortfall...and potentially further tax hikes…The Treasury suggested that the U-turn came after a better-than-expected forecast from the Office for Budget Responsibility (OBR). But this flip-flopping didn’t placate bond markets: how else to raise a reported £30bn without Reeves ditching her fiscal rules? The volte-face may have been explained by PM Starmer not wishing to anger the public or Labour MPs after a bruising week.
Apart from a “smorgasbord” of other tax tinkering, it’s likely the chancellor will freeze income tax thresholds beyond 2028, or lower the levels of basic, higher and additional rates of income tax. All remains speculation until the Budget itself.
Despite the OBR’s forecasts, the latest economic data showed UK growth slowed to 0.1% quarter-on-quarter to September – below the 0.2% expected and down from 0.3% growth over the prior quarter. A cyber-attack on Jaguar Land Rover hit car production and contributed to the fall. Month-on month GDP fell -0.1%. Although underlying growth may be better than these headlines, the economy lacks momentum. The services sector is expanding, but more slowly than the previous quarter, the unemployment rate rose to 5% over the quarter to September according to the Office for National Statistics (up from 4.8% in the three months to August) and wage growth is slowing.
Weak data won’t make good reading for the Chancellor but may trigger a December rate cut from the Bank of England. This still looks likely, but the prospect of smaller and messier fiscal tinkering will complicate the BoE’s job as it potentially seeks to offset growth-negative tax rises with rate cuts.
Crucial economic data will start to be released this week after the longest government shutdown in US history – 44 days – came to an end. The reports will provide policymakers an insight into the health of the US economy, in key areas including inflation and the labour market. The data-blackout caused uncertainty. During the shutdown, expectations of an interest rate cut at the US Federal Reserve’s December meeting fell from a near-certain 90% to a 50-50 coin toss today, despite there being no evidence of a strengthening labour market.
President Trump signed a federal funding bill ending the shutdown after it narrowly passed the House of Representatives in a 222-to-209 vote, following the Senate’s approval. The legislation releases funds to continue government activities until 30 January 2026. But if Republicans and Democrats don’t agree on spending after this date, the government may shut down again. Funding covering food assistance, military construction and agriculture will continue through to 30 September 2026.
