A new government can change the narrative, but it can’t escape the arithmetic. Rathbones UK Equity Income Fund Manager – Alan Dobbie, believes that policy discipline, not political rhetoric, will determine the outlook for UK investors.
A new government inevitably brings fresh priorities and policy ambitions, shifting attention to what might change. But for investors in UK stocks, the most important aspect of Prime Minister Andy Burnham’s government is not the switch in political style.
It’s how it handles the persistent fiscal constraints that continue to shape the UK economy.
The new administration faces a difficult balancing act: maintaining credibility with gilt investors, funding a more dangerous defence environment, investing enough in housing to lift potential growth, and deciding how long the state pension triple lock can remain untouched.
Each objective is reasonable in isolation. But together, they’re difficult to reconcile without either higher taxes, lower spending elsewhere, slower delivery, or a more explicit hierarchy of priorities.
The Burnham-Healey fiscal bind
The IMF’s latest health check on the UK economy captures the constraints well. It acknowledges that current strategy balances deficit reduction with growth-friendly spending, but warns that fiscal space remains limited and borrowing costs are elevated.
It also highlights longer-term pressures from an ageing population, defence commitments and the climate transition, pointing to difficult choices on spending, pensions and taxation.
That’s why the market test is not whether Prime Minister Burnham and his Chancellor John Healey can announce attractive priorities, but whether they can finance them while preserving the consolidation narrative.
The UK has benefited from being viewed as a relative fiscal consolidator. That credibility is valuable, but not unconditional.
Difficult trade-offs
Defence is the most awkward part of the bind. The strategic rationale for higher spending is clear, and the OBR fiscal watchdog assumes it will rise from its current level of 2.6% of GDP to 3.5% by 2035.
But higher defence spending absorbs resources that might otherwise be directed towards potentially growth-enhancing investment in infrastructure or housing.
Yes, greater housing supply requires upfront expenditure, but it can support labour mobility, construction activity and long-term growth. All this makes housing the most economically attractive part of the government agenda, but also one of the hardest to finance since its benefits arrive with a lag and depend on delivery. And gilt investors stay focused on the size of the deficit today.
The third constraint is pensions. The triple lock is not simply another spending commitment. By linking annual increases to the highest of earnings growth, inflation or 2.5%, it creates a structural upward drift in spending.
The OBR expects state pension costs to rise significantly as a share of GDP over coming decades, with the triple lock a meaningful contributor. For a government trying to spend more on defence and housing while maintaining fiscal credibility, it serves as a huge brake on fiscal flexibility just when that flexibility is most needed.
NHS pressures should be viewed slightly differently. NHS spending represents a structural challenge that will increasingly shape the UK’s public finances.
Demographics, chronic illness and healthcare costs point to a steadily rising health budget over coming decades. The government’s spending plans rely heavily on improved productivity, with NHS England targeting gains far above the historical trend.
Can greater productivity, smarter tech, more prevention and better community care credibly improve outcomes at lower costs? If they can, the NHS becomes a test case for public sector reform.
If they can’t, health spending will exert ever greater pressure on future tax revenues.
Similarly, social care should sit outside the core fiscal-bind framework. Burnham’s recent pledge to overhaul the provision of care is best interpreted as commitment to a reform agenda, rather than a major new spending pledge.
His focus has been on integrating care more effectively with the NHS, strengthening home care, improving workforce provision and accelerating structural reform. Again, he is emphasising better outcomes and more efficiency rather than simply spending more.
That does not mean social care is costless. Demographic pressures and rising provider costs imply additional funding will still be required.
But a more effective social care model could improve hospital discharge rates, cut workforce inactivity and ease pressure on NHS capacity. On the other hand, poorly designed reforms would simply add to the fiscal burden.
Why arithmetic still beats ambition
For markets, the implications are straightforward. A government that can demonstrate fiscal discipline while prioritising productive investment is likely to retain the confidence of gilt investors and avoid a sterling fiscal-risk discount.
Attempts to pursue multiple spending objectives without saving offsets suggest investors are likely to demand higher risk premia, driving up gilt yields, steepening the yield curve and exerting renewed pressure on sterling.
For investors in UK stocks, the opportunity lies not in the political rhetoric but in policy discipline. A credible consolidation-plus-investment strategy would support selective UK cyclicals, housebuilders, construction, banks and financials.
And losing fiscal credibility would have the opposite effect, raising discount rates and weakening the case for domestic UK assets.
The conclusion is clear. Burnham and Healey have scope to improve the composition of UK policy, particularly if housing, health, productivity and social care reform are treated as growth-enhancing reforms rather than unfunded promises.
But they can’t escape the challenging arithmetic. For investors, the critical question is not whether the agenda looks attractive. It’s whether it is financed, sequenced and credible enough for the gilt market to believe in it.
