The Treasury Select Committee has approved the appointment of Andy King, currently OBR Chief of Staff, to join the Budget Responsibility Committee.

Borrowing in May was down on last year, although this reflects spending data that are still very provisional. Borrowing for 2017-18 was revised down further, but again full outturns will not be available until at least September.

The Chancellor of the Exchequer has nominated Andy King to join the OBR’s Budget Responsibility Committee (BRC) and Bronwyn Curtis OBE to join the OBR’s oversight board as a non-executive member.

Last year’s budget deficit has been revised £2 billion lower to £40.5 billion, with departments thought to have undershot their spending limits by more than originally estimated. But the figures are still liable to significant further revision.

At the request of the Treasury Committee, the OBR has confirmed that it should be able to incorporate an October EU exit agreement in an early December Budget forecast, updating its existing Brexit assumptions as necessary. But it is not clear how firm or detailed the agreement will be and important policy questions are bound…

Public sector net borrowing in 2017-18 is provisionally estimated at £42.6 billion, £2.5 billion lower than we forecast at the Spring Statement in March. Lower-than-expected local authority borrowing more than explains that difference, but firm outturn data on that will not be available before September.

Robert Chote distils the key messages from our latest Economic and fiscal outlook – published today – in his press conference presentation and accompanying speaking note.

We have revised GDP growth up a little in the near term thanks to a stronger world economy, but the medium-term outlook is little changed. And we have revised borrowing down thanks to stronger receipts, but the improvement is largely cyclical. So headroom against the Government’s fiscal targets is virtually unchanged from the autumn.

Relatively little time has passed since our November forecast and the outlook for the economy and public finances looks broadly the same. The economy has slightly more momentum in the near term, thanks to the unexpected strength of the world economy, but there seems little reason to change our view of its medium-term growth potential….

January is the biggest month of the year for tax receipts. Self-assessment income tax receipts fell on a year earlier, but by much less than our November forecast assumed. Uncertainty remains – especially around local authority borrowing – but it is now clear that 2017-18 borrowing will be lower than we forecast in November.

The introduction of universal credit (UC) is one of the most significant reforms to the welfare system since the Beveridge Report. It will replace six existing means-tested benefits and tax credits for people of working age, paying more than £60 billion a year to around 7 million households by the time it is fully rolled…

The introduction of Universal Credit is forecast to reduce welfare spending by about £1bn a year by 2022-23. But the fiscal impact is much more uncertain than that suggests, according to our latest Welfare trends report.

The budget deficit fell in December relative to the previous year and remains down year-to-date in 2017-18, partly driven by lower EU contributions. We expect weaker self-assessment receipts to push borrowing higher from January as income shifting effects from last year unwind.
