Higher debt interest payments account for roughly two-thirds of the increase in borrowing. This is only partly related to the market reaction to the disastrous mini budget. It is much more the result of higher interest rates in response to inflation at four-decade highs. This in turn is the result of both domestic monetary policy decisions, resulting from Bank of England actions to raise interest rates, and global actions as central banks around the world scramble to tighten policy. Nonetheless, it is incongruous that the UK government has implemented a tighter fiscal stance which is partly the result of tighter monetary conditions. Any fears that fiscal dominance is a theme in the UK policy environment can be set aside for now.
The government did attempt to offset some of the fiscal damage resulting from these two factors by introducing a series of measures to close the gap. Whilst borrowing is higher than projected nine months ago, it is less than would be the case had not the government also implemented measures that by fiscal 2027-28 imply a fiscal tightening of £54.9bn, which translates into a fiscal contraction equivalent to 0.5% of GDP for each of the next five years. Spending cuts account for £30bn of the measures, although these are not scheduled to kick in until after the next election, whilst the remainder is derived from higher tax revenues (chart).
There is an important political dimension to the latest budget plans. The fact that spending cuts only take effect in two years’ time in effect mean that the government is setting an elephant trap for the next government. If Labour win the election, which is scheduled no later than January 2025 and which seems likely on the basis of recent polling evidence, they will have to decide whether to go along with the current government’s fiscal plans or take a risk with new plans of their own, having been a major critic of the austerity policies in place since 2010. If the Tories win … well that’s a bridge they will cross when they come to it.
What is the goal of fiscal policy?
All of this leads to the real question: What exactly is the goal of fiscal policy? In recent weeks the debate has been all about the ideological split within the Conservative Party with supporters of a big state pitted against those advocating a small state, and there is a sense that the latter group is very much on the back foot. Last week’s efforts were clearly aimed at getting the markets back onside following the September shenanigans. Whilst it is important not to alienate one’s creditor, there was a nagging sense that too much emphasis was placed on placating markets. The budget balance cannot simply be an end in itself.
This raises the question of how much fiscal space the UK has and how well it stacks up against comparable economies. Conventionally, the degree of fiscal space is determined by the level of debt which markets believe an economy can carry without jeopardising the overall economic and fiscal position. It is true that UK debt gross debt levels are high – 97% of GDP at the end of fiscal 2021-22, rising to a peak of around 107% by early 2024 on the basis of the OBR’s forecast. Looking across Europe, however, the likes of Spain, France and Italy all have higher debt ratios (118%, 113% and 150% respectively) and none of them issue debt in a currency whose issuance they control. There is not the same debate about the need to wear the fiscal hairshirt in these countries, despite a worse fiscal position. Fear of the markets is currently the dominant theme of British fiscal policy rather than a coherent attempt to use policy in a more strategic sense.
What should policy be doing?
Successive governments have failed to have a grown-up debate about appropriate levels of tax. The demographic dividend that allowed the Thatcherite Tory party to cut taxes has ceased to be a tailwind and is now beginning to act as a fiscal headwind. Whilst it has long been said that the British electorate wants Scandinavian-level public services whist paying US-level taxes, it is currently getting neither (almost the opposite, in fact). Boris Johnson’s levelling-up agenda has been consigned to the dustbin and redistribution is still a dirty word in many areas of government.
Whilst Truss’s highly regressive fiscal plans have been found wanting, we are not yet at the stage where we are talking about what different things we might want fiscal policy to do. If we are serious about a transition to a green economy, for example, a big public investment in this area might pay dividends. I have also long advocated investment in making the economy fit to cope with climate change – again, government can play a role. However, we have missed our chance to use the lowest interest rates in history to fund such investment. But even if the government does not want to do any of these things, taxes will have to rise in order to provide the levels of public services that people have come to expect. In order to do so, we need to start thinking outside the box on taxes.
Governments over the years have tinkered with income and corporate taxes as the main areas of focus. I have in the past suggested that wealth taxes are an area that should at least be looked at more closely. Tax Justice UK, a lobby group which advocates for a “sustainable, fair and effective tax system” has suggested a number of tax loopholes which could be closed and in the process raise substantial revenue. Amongst the measures it proposes are equalizing capital gains with income tax rates, raising up to £14 bn a year (a measure which was originally championed by the Office of Tax Simplification). Extending national insurance to investment income could raise a further £8.6 bn a year. In all, it has identified measures which could generate an additional annual £37bn of income.
The bottom line is that there is no obvious need to squeeze spending quite as hard as the government outlined last week. Austerity was a bad policy in 2010. It is an even worse response today, with public services cut to the bone in many areas. Whilst there are many who argue that this is all to do with Brexit, it is not. We are at a point where demographics have collided with a low productivity economy to leave the government scrambling to provide a fix. Brexit is not helping, of course, since it will act to depress growth in the longer term and widen the budget gap. But in order to tackle the problems, we need to get away from the sterile discussion about further raising income or corporate taxes. It is about the need for a fundamental reform of the tax system.
