Donald Trump is keen to lower US interest rates substantially and rapidly in order to provide a boost to the US economy. He is also keen to reduce the cost of living for US citizens and sees lower interest rates as a means of reducing the burden of debt servicing for both consumers and firms alike.
But interest rates are set by the US central bank, the Federal Reserve (the ‘Fed’), which is formally independent from government. This independence is seen as important for providing stability to the US economy and removing monetary policy from short-term political pressures to cut interest rates. Succumbing to political pressures would be likely to create uncertainty and damage long-term stability and growth.
Yet President Trump is pushing the Fed to lower interest rates rapidly and despite three cuts in a row of 0.25 percentage points in the last part of 2025 (see chart below), he thinks this as too little and is annoyed by suggestions that the Fed is unlikely to lower rates again for a while. He has put great pressure on Jerome Powell, the Fed Chair, to go further and faster and has threatened to replace him before his term expires in May this year. He has also made clear that he is likely to appoint someone more willing to cutting rates.
The Federal Reserve headquarters in Washington is currently being renovated. The nine-year project is costing $2.5 billion and is due to be completed next year. President Trump has declared that the project’s costs are excessive and unnecessary.
On 11 January, Federal prosecutors confirmed that they were opening a criminal investigation into Powell, accusing him of lying to Congress in his June 2025 testimony regarding the scope and costs of the renovations.
Powell responded by posting a video in which he claimed that the real reason that he was being threatened with criminal charges was not because of the renovations but because the Fed had ignored President Trump’s pressure and had set interest rates:
based on our best assessment of what will serve the public, rather than following the preferences of the President. This is about whether the Fed will be able to continue to set interest rates based on evidence and economic conditions – or whether, instead, monetary policy will be directed by political pressure or intimidation.
The Fed’s mandate
The Federal Reserve Board decides on monetary policy and then the Federal Open Market Committee (FOMC) decides how to carry it out. It decides on interest rates and asset sales or purchases. The FOMC meets eight times a year.
The Fed is independent of both the President and Congress, and its Chair is generally regarded as having great power in determining the country’s economic policy.
Since 1977, the Fed’s statutory mandate has been to promote the goals of stable prices and maximum employment. Because of the reference to both prices and employment, the mandate is commonly referred to as a ‘dual mandate’. Its inflation target is 2 per cent over the long run with ‘well anchored’ inflationary expectations.
The dual mandate is unlike that of the Bank of England, the European Central Bank, the Bank of Japan and most other central banks, which all have a single key mandate of achieving a target of a 2 per cent annual rate of consumer price inflation over a particular time period.
With a dual mandate, the two objectives may well conflict from time to time. Moreover, changes in monetary policy affect these objectives with a lag and potentially over different time horizons. Hence, an assessment may have to be made of which is the most pressing problem. This does give some leeway in setting interest rates somewhat lower than if there were a single inflation-rate target. Nevertheless, the assessment is in terms of how best to achieve the mandate and not to meet current political goals.
Statement by former Fed Chairs and Governors
On 12 January, three former Chairs of the Federal Reserve (Janet Yellen, Ben Bernanke and Alan Greenspan), four former Treasury Secretaries (Timothy Geithner, Jacob Lew, Henry Paulson and Robert Rubin) and seven other top former economic officials issued the following statement (see Substack link in the Articles section below):
The Federal Reserve’s independence and the public’s perception of that independence are critical for economic performance, including achieving the goals Congress has set for the Federal Reserve of stable prices, maximum employment, and moderate long-term interest rates. The reported criminal inquiry into Federal Reserve Chair Jay Powell is an unprecedented attempt to use prosecutorial attacks to undermine that independence. This is how monetary policy is made in emerging markets with weak institutions, with highly negative consequences for inflation and the functioning of their economies more broadly. It has no place in the United States whose greatest strength is the rule of law, which is at the foundation of our economic success.
Response of investors
What will happen to the dollar, US bond prices, share prices and US inflation, and what will happen to investment, depends on how people respond to the threat to the Fed’s independence. Initially, there was little response from markets, with investors probably concluding that President Trump is unlikely to be able to sway FOMC members. What is more, several Republican lawmakers have begun criticising the Trump administration’s criminal investigation, making it harder for the President to influence Fed decisions.
Even if Powell is replaced, either in the short term or in May, by a chair keen to pursue the Trump agenda, that chair will still be just one of twelve voting members of the FOMC.
Seven are appointed by the President, but serve for staggered 14-year terms. Four have been appointed by President Trump, but the other three were appointed by President Biden, although one – Lisa Cook – is being indicted by the Supreme Court for mortgage fraud, with the hearing scheduled for January 21. She claims that this is a trumped-up charge to provide grounds for removing her from the Fed. If she is removed, President Trump could appoint a replacement minded to cut rates.
The other five members include the President of the New York Fed and four of the eleven other regional Fed Presidents serving in rotation. These four are generally hawkish and would oppose early rate cuts.
Thus it is unlikely that President Trump will succeed in pushing the Fed to lower interest rates earlier than they would have done. For that reason, markets have remained relatively sanguine.
Nevertheless, Donald Trump’s actions could well cause investors to become more worried. Will he try to find other ways to undermine the Fed? Will his actions over Venezuela, Cuba, Greenland and Iran, let alone his policies towards Ukraine and Russia and towards Israel and Gaza, heighten global uncertainty? Will his actions towards Venezuela and his desire to take over Greenland embolden China to attempt to annex Taiwan, and Russia to continue to resist plans to end the war in Ukraine or to make stronger demands?
Such developments could cause investor confidence to wane and for stock markets to fall. Time will tell. I think we need a crystal ball!

The productivity gap between the UK and its main competitors is significant. In 2024, compared to the UK, output per hour worked was 10.0% higher in France, 19.8% higher in Germany and 41.1% higher in the USA. These percentages are in purchasing-power parity terms: in other words, they reflect the purchasing power of the respective currencies – the pound, the euro and the US dollar.
GDP per hour worked (in PPP terms) is normally regarded as the best measure of labour productivity. An alternative measure is GDP per worker, but this does not take into account the length of the working year. Using this measure, the gap with the USA is even higher as workers in the USA work longer hours and have fewer days holiday per year than in the UK.
The productivity gap is not a new phenomenon. It has been substantial and growing over the past 20 years. (The exception was in 2020 during lockdowns when many of the least productive sectors, such as hospitality, were forced to close temporarily.)
The productivity gap is shown in the two figures. Both figures show labour productivity for the UK, France, Germany and the USA from 1995 to 2024.
Figure 1 shows output (GDP) per hour, measured in US dollars in PPP terms.
Figure 2 shows output (GDP) per hour relative to the UK, with the UK set at 100. The gap narrowed somewhat up to the early 2000s, but since then has widened.
Low UK productivity has been a source of concern for UK governments and business for many years. Not only does it constrain the growth in living standards, it also make the UK less attractive as a source of inward investment and less competitive internationally.
Part of the reason for low UK productivity compared to that in other countries is a low level of investment. As a proportion of GDP, the UK has persistently had the lowest, or almost the lowest, level of investment of its major competitors. This is illustrated in Table 1.

It is generally recognised by government, business and economists that if the economy is to be successful, the productivity gap must be closed. But there is no ‘quick fix’. The policies necessary to achieve increased productivity are long term. There is also a recognition that the productivity problem is a multi-faceted one and that to deal with it requires policy initiatives on a broad front: initiatives that encompass institutional changes as well as adjustments in policy.
So what can be done to improve productivity and how can this be achieved at the micro as well as the macro level?
Improving productivity: things that government can do
Encouraging investment. Over the years, UK governments have increased investment allowances, enabling firms to offset the cost of investment against pre-tax profit, thereby reducing their tax liability. For example, in the UK, companies can offset a multiple of research and development costs against corporation tax. The rate of relief for small and medium-sized enterprises (SMEs) allows companies that work in science and technology to deduct an extra 86% of their qualifying expenditure from their trading profit in addition to the normal 100% deduction: i.e. a total of 186% deduction. Meanwhile, since April 2016, larger companies have been able to claim a R&D expenditure credit, initially worth 11 per cent of R&D expenditures, then 12 per cent from 2018 and 13 per cent from 2020. This was then raised to 20 per cent from 2023.
Strengthening competition. A number of studies have revealed that, with increasing market share, business productivity growth slows. As a result, government policy sought to strengthen competition policy. The Competition Act 1998, which came into force in March 2000, and the Enterprise Act of 2002, enhanced the powers of the Office of Fair Trading (OFT) (a predecessor to the Competition and Markets Authority) in respect to dealing with anti-competitive practices. It was given the ability to impose large fines on firms which had been found guilty of exploiting a dominant market position. Today, one of the strategic goals of the Competition and Markets Authority (CMA) is the aim of ‘extending competition frontiers’ in order to improve the way competition works.
Encouraging an enterprise culture. The creation of an enterprise culture is seen as a crucial factor not only to encourage innovation but also to stimulate technological progress. Innovation and technological progress are crucial to sustaining growth and raising living standards. The UK government launched the Small Business Service in April 2000, later renamed Business and Industry. Its role is to co-ordinate small-business policy within government and liaise with business, providing advice and information. However, according to the OECD, there remains considerable scope for increasing the level of government support for entrepreneurship in the UK.
Improving productivity: things that organisations can do
In the podcast from the BBC’s The Bottom Line series, titled ‘Productivity: How Can British Business Work Smarter’ (see link below), Evan Davis and guests discuss what productivity really looks like in practice – from offices and factories, to call centres and operating theatres.’ The episode identifies a number of ways in which labour productivity can be improved. These include:
- People could work harder;
- Workers could be better trained and more skilled and thus able to produce more per hour;
- Capital could be increased so that workers have more equipment or tools to enable them to produce more, or there could be greater automation, releasing labour to work on other tasks;
- Workplaces could be arranged more efficiently so that less time is spent moving from task to task;
- Systems could put in place to ensure that tasks are done correctly the first time and that time is not wasted having to repeat them or put them right;
- Workers could be better incentivised to work efficiently, whether through direct pay or promotion prospects, or by increasing job satisfaction or by management being better attuned to what motivates workers and makes them feel valued;
- Firms could move to higher-value products, so that workers produce a greater value of output per hour.
The three contributors to the programme discuss various initiatives in their organisations (an electronics manufacturer, NHS foundation trusts and a provider of office services to other organisations).
They also discuss the role that AI plays, or could play, in doing otherwise time-consuming tasks, such as recording and paying invoices and record keeping in offices; writing grants or producing policy documents; analysing X-ray results in hospitals and performing preliminary diagnoses when patients present with various symptoms; recording conversations/consultations and then sorting, summarising and transcribing them; building AI capabilities into machines or robots to enable them to respond to different specifications or circumstances; software development where AI writes the code. Often, there is a shortage of time for workers to do more creative things. AI can help release more time by doing a lot of the mundane tasks or allowing people to do them much quicker.
There are huge possibilities for increasing labour productivity at an organisational level. The successful organisations will be those that can grasp these possibilities – and in many cases they will be incentivised to so so as it will improve their profitability or other outcomes.

The gold market has become one of the most talked-about commodity markets in 2025, with prices reaching record highs. This is largely due to increased demand from investors, who see gold as a ‘safe haven’ during times of economic and political uncertainty. Central banks are also buying more gold as a way to reduce their reliance on currencies like the US dollar. With many analysts predicting prices could reach over $4000 per ounce in the next year, the gold market is showcasing how supply and demand, confidence, and global events can all influence a commodity market.
The commodities market is where basic agricultural products, raw materials and metals, such as gold, are bought and sold, often in large quantities and across global exchanges. Commodities are typically traded either in their physical form (like gold bars) at current market prices (spot prices) or through financial contracts, where investors buy or sell in futures markets. These are where a price is agreed today to buy or sell on a specific future date.
As with other commodities, the price of gold is determined by supply and demand. Demand for gold typically rises during times of economic uncertainty as investors want a safer store of value. This results in an increase in its price. Supply and demand, and hence price, also respond to other factors, including interest rates, currency movements, economic growth and growth prospects, and geopolitical events.
Record high prices
This year, the gold market has seen a remarkable rally, with the price of gold hitting a record high. Demand for the precious metal has resulted in spot prices surging over 35% to date (see the chart: click here for a PowerPoint). Rising prices earlier this year have been attributed to the US President, Donald Trump, announcing wide-ranging tariffs which have upset global trade. On 2 September, the spot gold price hit $3508.50 per ounce, continuing its upwards trend.
The price has also been lifted by expectations that the Federal Reserve (the US central bank) will cut its key interest rate, making gold an even more attractive prospect for investors. If the Federal Reserve cuts interest rates, the price of gold usually increases. This is because gold does not pay any interest or yield, so when interest rates are high, investors can earn better returns from alternatives, such as savings accounts or bonds. However, when interest rates fall, those returns become less attractive, making gold relatively more appealing.
Lower interest rates also tend to weaken the US dollar, which makes gold cheaper for foreign buyers, increasing global demand. Since gold is priced in dollars, a weaker dollar usually leads to higher gold prices.
Additionally, interest rate cuts are often a response to economic problems or uncertainty. As gold is viewed as a safer asset for investors during times of economic uncertainty, investors will typically increase their demand.
Unlike the market for currencies or shares, gold doesn’t rely on the performance of a government or company. This makes it attractive when people are worried about things like inflation, recession, war or stock market crashes. Gold is thus seen as a ‘safe haven’.
Gold and the Federal Reserve
The rise in the price of gold by more than a third this year can be linked to the US election last year, according to the director of research at BullionVault (see the BBC article below). Attitudes of the Trump administration towards the Federal Reserve have created concerns among investors. Fears that the US administration could erode the independence of the world’s most important central bank have fuelled the latest flows into the metal, which is traditionally viewed as a hedge against inflation.
According to the BBC article, Derren Nathan from Hargreaves Lansdown claims that it is Trump’s ‘attempts to undermine the independence of the Federal Reserve Bank’ that were ‘driving renewed interest in safe haven assets, including gold’. Investors are concerned that a politicised Fed would be more inclined to cut interest rates than would otherwise be the case, sending long-term inflation expectations higher.
This could lead to fears that future interest rates would then be pushed higher. This would increase the yields on longer-term government bonds by pushing down their price, as investors demand higher compensation for the increased risk of higher future interest rates reducing the value of their fixed-rate investments. This would force the US Treasury to pay higher interest on new bonds, making it more expensive to service US government debt.
Expected price rises for 2026
As we saw above, it is predicted that the price of gold will rise to $4000 per ounce next year. However, if the market sees investors move away from dollar assets, such as US Treasuries, the price increases would be even higher. Daan Struyven, co-head of global commodities research at Goldman Sachs explains ‘If 1 per cent of the privately owned US Treasury market were to flow to gold, the gold price would rise to nearly $5000 per troy ounce’ (see Financial Times article below).
If the Federal Reserve does come under political pressure, it could affect the stability of the US economy and beyond. When gold prices rise sharply, demand usually falls in countries like China and India, which are the world’s largest buyers of gold jewellery. However, in 2025, this trend has changed. Instead of reducing their gold purchases, people in these countries have started buying investment gold, such as bars and coins, showing a shift in consumer behaviour from jewellery to investment assets.
At the same time, global events are also influencing the gold market. Suki Cooper, a metals analyst at Standard Chartered, said that events like Russia’s invasion of Ukraine have added to political uncertainty, which tends to increase demand for gold as a safe-haven asset. She also highlighted how changes in international trade policies have disrupted supply chains and contributed to higher inflation, both of which have made gold more attractive to investors. Additionally, a weaker US dollar earlier in the year made gold cheaper for buyers using other currencies, which boosted global demand even further.
Conclusion
Although the gold market is expected to remain strong over the next six months, some uncertainty remains. Many analysts predict that gold prices will stay high or even increase further, especially if interest rates in the US are cut as expected. Continued global instability, is also likely to keep demand for gold as a safe haven high. At the same time, if inflation stays elevated or trade disruptions continue, more investors may turn to gold to protect their wealth.
However, if economic conditions stabilise or interest rates rise again, gold demand could fall slightly, leading to a potential dip in prices. Overall, the outlook for gold remains positive, but sensitive to changes in global economic and political events.

The UK’s poor record on productivity since the 2008 financial crisis is well documented, not least in this blog series. Output per worker has flatlined over the 17 years since the crisis. As was noted in the blog, The UK’s poor productivity record, low UK productivity is caused by a number of factors, including the lack of investment in training, the poor motivation of many workers and the feeling of being overworked, short-termism among politicians and management, and generally poor management practices.
One of the most significant issues identified by analysts and commentators is the lack of investment in physical capital, both by private companies and by the government in infrastructure. Gross fixed capital formation (a measure of investment) has been much lower in the UK compared to international competitors.
From Figure 1 it can be observed that, since the mid-1990s, the UK has consistently had lower investment as a percentage of GDP compared to other significant developed market economies. The cumulative effect of this gap has contributed to lower productivity and lower economic growth.
Interestingly, since the financial crisis, UK firms have had high profitability and associated high cash holdings. This suggests that firms have had a lot of financial resources to reinvest. However, data from the OECD suggests that reinvestment rates in the UK, typically 40–50% of profit, are much lower than in many other OECD countries. In the USA the rate is 50%, in Germany 60–70% and in Japan 70%+. There is much greater emphasis in the UK on returning funds to shareholders through dividends and share buybacks. However, the reinvestment of much of this cash within firms could have gone some way to addressing the UK’s investment gap – but, it hasn’t been done.
Analysis by the OECD suggest that, while the cost of financing investment has declined since the financial crisis, the gap between this and the hurdle rate used to appraise investments has widened. Between 2010 and 2021 the difference nearly doubled to 4%. This increase in the hurdle rate can be related to increases in the expected rate of return by UK companies and their investors.
In this blog we will analyse (re)investment decisions by firms, discussing how increases in the expected rate of return in the UK raise the hurdle rate used to appraise investments. This reduces the incentive to engage in long-term investment. We also discuss policy prescriptions to improve reinvestment rates in the UK.
Investment and the expected rate of return
Investment involves the commitment of funds today to reap rewards in the future. This includes spending on tangible and intangible resources to improve the productive capacity of firms. Firms must decide whether the commitment of funds is worthwhile. To do so, economic theory suggests that they need to consider the compensation required by their provider of finance – namely, investors.
What rewards do investors require to keep their funds invested with the firm?
When conducting investment appraisal, firms compare the estimated rate of return from an investment with the minimum return investors are prepared to receive (termed the ‘expected return’). Normally this is expressed as a percentage of the initial outlay. Firms have to offer returns to investors which are equal to or greater than the minimum expected return – the return that is sufficient to keep funds invested in the firm. Therefore, returns above this minimum expected level are termed ‘excess returns’.
When firms conduct appraisals of potential investments, be it in tangible or intangible capital, they need to take into account the fact that net benefits, expressed as cash flows, will accrue over the life of the investment, not all at once. To do this, they use discounted cash flow (DCF) analysis. This converts future values of the net benefits to their present value. This is expressed as follows:

Where:
NPV = Net present value (discounted net cash flows);
K = Capital outlay (incurred at the present time);
C = Net cash flows (occur through the life of the investment project);
r = Minimum expected rate of return.
In this scenario, the investment involves an initial cash outlay (K), followed in subsequent periods by net cash inflows each period over the life of the investment, which in this case is 25 years. All the cash flows are discounted back to the present so that they can be compared at the same point in time.
The discount rate (r) used in appraisals to determine the present value of net cash flows is determined by the minimum expected return demanded by investors. If at that hurdle rate there are positive net cash flows (+NPV), the investment is worthwhile and should be pursued. Conversely, if at that hurdle rate there are negative net cash flows (–NPV), the investment is not worthwhile and should not be pursued.
According to economic theory, if a firm cannot find any investment projects that produce a positive NPV, and therefore satisfy the minimum expected return, it should return funds to shareholders through dividends or share buybacks so that they can invest the finance more productively.
Firm-level data from the OECD suggest that UK firms have had higher profits and this has been associated with increased cash holdings. But, due to the higher hurdle rate, less investment is perceived to be viable and thus firms distribute more of their profits through dividends and share buybacks. These payouts represent lost potential investment and cumulatively produce a significant dent in the potential output of the UK economy.
Why are expected rates of return higher in the UK?
This higher minimum rate of expected return can be explained by factors influencing its determinants; opportunity cost and risk/uncertainty.
Higher opportunity cost. Opportunity cost relates to the rate of return offered by alternatives. Investors and, by implication firms, will have to consider the rate of return offered by alternative investment opportunities. Typically, investors have focused on interest rates as a measure of opportunity cost. Higher interest rates raise the opportunity cost of an investment and increase the minimum expected rate of return (and vice versa with lower interest rates).
However, it is not interest rates that have increased the opportunity cost, and hence the minimum expected rate of return associated with investment, in the UK since the financial crisis. For most of the period since 2008, interest rates have been extremely low, sitting at below 1%, only rising significantly during the post-pandemic inflationary surge in 2022. This indicates that this source of opportunity cost for the commitment of business investment has been extremely low.
However, there may be alternative sources of opportunity cost which are pushing up the expected rate of return. UK investors are not restricted to investing in the UK and can move their funds between international markets determined by the rate of return offered. The following table illustrates the returns (in terms of percentage stock market index gain) from investing in a sample of UK, US, French and German stock markets between August 2010 and August 2025.

When expressed in sterling, returns offered by UK-listed companies are lower across the whole period and in most of the five-yearly sub-periods. Indeed, the annual equivalent rate of return (AER) for the FTSE 100 index across the whole period is less than half that of the S&P 500. The index offered a paltry annual return of 2.57% between 2015 and 2020, while the US index offered a return of 16.48%. Both the French and German indices offered higher rates of return, in the latter part of the period particularly. This represents a higher opportunity cost for UK investors and may have increased their expectations about the return they require for UK investments.
Greater perceived risk/uncertainty. Expected rates of return are also determined by perceptions of risk and uncertainty – the compensation investors need to bear the perceived risk associated with an investment. Investors are risk averse. They demand higher expected return as compensation for higher perceived risk. Higher levels of risk aversion increase the expected rate of return and related investment hurdle rates.
There has been much discussion of increased uncertainty and risk aversion among global investors and firms (see the blogs Rising global uncertainty and its effects, World Uncertainty Index, The Chancellor’s fiscal dilemma and Investment set to fall as business is baffled by Trump). The COVID-19 pandemic, inflation shocks, the war in Ukraine, events across the Middle East and the trade policies adopted by the USA in 2025 have combined to produce a very uncertain business environment.
While these have been relatively recent factors influencing world-wide business uncertainty, perceptions of risk and uncertainty concerning the UK economy seem to be longer established. To measure policy-related economic uncertainty in the UK, Baker, Bloom and Davis at www.PolicyUncertainty.com construct an index based on the content analysis of newspaper articles mentioning terms reflecting policy uncertainty.
Figure 2 illustrates the monthly index from 1998 to July 2025. The series is normalised to standard deviation 1 prior to 2011 and then summed across papers, by month. Then, the series is normalised to mean 100 prior to 2011.
Some of the notable spikes in uncertainty in the UK since 2008 have been labelled. Beginning with the global financial crisis, investors and firms became much more uncertain. This was exacerbated by a series of economic shocks that hit the economy, one of which, the narrow vote to leave the European Union in 2016, was specific to the UK. This led to political turmoil and protracted negotiations over the terms of the trade deal after the UK left. This uncertainty has been exacerbated recently by the series of global shocks highlighted above and also the budget uncertainty of Liz Truss’s short-lived premiership and now the growing pressure to reduce government borrowing.
While spikes in uncertainty occurred before the financial crises, the average level of uncertainty, as measured by the index, has been much higher since the crisis. From 1998 to 2008, the average value was 89. Since 2008, the average value has been 163. Since the Brexit vote, the average value has been 185. This indicates a much higher perception of risk and uncertainty over the past 15 year and this translates into higher minimum expected return as compensation. Consequently, this makes many long-term investment projects less viable because of higher hurdle rates. This produces less productive investment in capital, contributing significantly to lower productivity.
Policy proposals
There has been much debate in the UK about promoting greater long-term investment. Reforms have been proposed to improve public participation in long-term investment through the stock market. To boost investment, this would require the investing public to be prepared to accept lower expected returns for a given level of risk or accept higher risk for a given level of returns.
Evidence suggests that the appetite for this may be very low. UK savers tend to favour less risky and more liquid cash deposits. It may be difficult to encourage them to accept higher levels of risk. In any case, even if they did, many may invest outside the UK where the risk-return trade-off is more favourable.
Over the past 10 years, policy uncertainty has played a significant role in deterring investment. So, if there is greater continuity, this may then promote higher levels of investment.
The Labour government has proposed policies which aim to share or reduce the risk/uncertainty around long-term investment for UK businesses. For instance, a National Wealth Fund (NWF) has been established to finance strategic investment in areas such as clean energy, gigafactories and carbon capture. Unfortunately, the Fund is financed by borrowing through financial markets and the amount expected to be committed over the life of the current Parliament is only £29 billion, assuming that private capital matches public commitments in the ratio expected. It is questionable whether the Fund’s commitment will be sufficient to attract private capital.
Alternatively, Invest 2035 is a proposal to create a stable, long-term policy environment for business investment. It aims to establish an Industrial Strategy Council for policy continuity and to tackle issues like improving infrastructure, reducing energy costs and addressing skills gaps. Unfortunately, even if there is some attempt at domestic policy stability, the benefits may be more than offset by perceptions around global uncertainty, which may mean that UK investors’ minimum expected rates of return remain high and long-term investment low for the foreseeable future.

The UK Chancellor of the Exchequer, Rachel Reeves, will present her annual Budget in late autumn. It will involve some hard economic and political choices. The government would like to spend more money on improving public services but has pledged not to raise taxes ‘on working people’, which is interpreted as not raising the rates of income tax, national insurance for employees and the self-employed, and VAT. What is more, government borrowing is forecast by the OBR to be £118 billion, or nearly 4.0% of GDP, for the the year 2025/26. This is a fall from the 5.1% in 2024/25 and is well below the 15.0% in 2020/21 during the pandemic. But it is significantly above the 2.1% in 2018/19.
The government has pledged to stick to its two fiscal rules. The first is that the day-to-day, or ‘current’, budget (i.e. excluding investment) should be in surplus or in deficit of no more than 0.5 per cent of GDP by 2029/30 (or the third year of the rolling forecast period from the 2026/27 Budget). This allows investment to be funded by borrowing. The second rule is that public-sector net debt, which includes public-sector debt plus pension liabilities minus equity, loans and other financial assets, should be falling by 2029/30 (or the third year of the rolling forecast period from the 2026/27 Budget). The current budget deficit (i.e. excluding borrowing for investment) was forecast by the OBR in March to be 1.2% of GDP for 2025/26 (see Chart 1) and to be a surplus of 0.3% in 2029/30 (£9.9 billion). (Click here for a PowerPoint of the chart.)
The OBR’s March forecasts, therefore, were that the rules would be met with current policies and that the average rate of economic growth would be 1.8% over the next four years.
However, there would be very little room for manoeuvre, and with global political and economic uncertainty, including the effects of tariffs, climate change on harvests and the continuing war in Ukraine, the rate of economic growth might be well below 1.8%.
The March forecasts were based on the assumption that inflation would fall and hence that the Bank of England would reduce interest rates. Global pressure on inflation, however, might result in inflation continuing to be above the Bank of England’s target of 2%. This would mean that interest rates would be slow to fall – if at all. This would dampen growth and make it more expensive for the government to service the public-sector debt, thus making it harder to reduce the public-sector deficit.
A forecast earlier this month by the National Institute for Economic and Social Research (NIESR) (see link below and Chart 2) reflects these problems and paints a gloomier picture than the OBR’s March forecast. The NIESR forecasts that GDP will grow by only 1.3 per cent in 2025, 1.2 per cent in 2026, 1.1% in 2027 and 1.0% in 2028, with the average for 2025 to 2023 being 1.13%. This is the result of high levels of business uncertainty and the effects of tariffs on exports. With no change in policy, the current deficit would be £41.2 billion in the 2029/30 financial year. Inflation would fall somewhat, but would stick at around 2.7% from 2028 to 2030. Net debt would be rising in 2029/30 &ndash but only slightly, from 98.7% to 99.0%. (Click here for a PowerPoint of the chart.)
So what are the policy options open to the government for dealing with a forecast current budget deficit of £41.2 billion (1.17% of GDP)? There are only three broad options.
Increase borrowing
One approach would be to scrap the fiscal rules and accept increased borrowing – at least temporarily. This would avoid tax increases or expenditure cuts. By running a larger budget deficit, this Keynesian approach would also have the effect of increasing aggregate demand and, other things being equal, could lead to a multiplied rise in national income. This in turn would lead to higher tax revenues and thereby result in a smaller increase in borrowing.
There are two big problems with this approach, however.
The first is that it would, over time, increase the public-sector debt and would involve having to spend more each year on servicing that debt. This would leave less tax revenue for current spending or investment. It would also involve having to pay higher interest rates to encourage people to buy the additional new government bonds necessary to finance the increased deficit.
The second problem is that the Chancellor has said that she will stick to the fiscal rules. If she scraps them, if only temporarily, she runs the risk of losing the confidence of investors. This could lead to a run on the pound and even higher interest rates. This was a problem under the short-lived Liz Truss government when the ‘mini’ Budget of September 2022 made unfunded pledges to cut taxes. There was a run on the pound and the Bank of England had to make emergency gilt purchases.
One possibility that might be more acceptable to markets would be to rewrite the investment rule. There could be a requirement on government to invest a certain proportion of GDP (say, 3%) and fund it by borrowing. The supply-side benefits could be faster growth in potential output and higher tax revenue over the longer term, allowing the current deficit rule to be met.
Cut government expenditure
Politicians, especially in opposition, frequently claim that the solution is to cut out public-sector waste. This would allow public expenditure to be cut without cutting services. This, however, is harder than it might seem. There have been frequent efficiency drives in the public sector, but from 1919 to 2023 public-sector productivity fell by an average of 0.97% per year.
Causes include: chronic underinvestment in capital, resulting in outdated equipment and IT systems and crumbling estates; decades of underfunding that have left public services with crumbling estates, outdated equipment and insufficient IT systems; inconsistent, short-term government policy, with frequent changes in government priorities; bureaucratic systems relying on multiple legacy IT systems; workforce challenges, especially in health and social care, with high staff turnover, recruitment difficulties, and a lack of experienced staff.
The current government has launched a Public Sector Productivity Programme. This is a a cross-government initiative to improve productivity across public services. Departments are required to develop productivity plans to invest in schemes designed to achieve cost savings and improve outcomes in areas such as the NHS, police, and justice system. A £1.8 billion fund was announced in March 2024, to support public-sector productivity improvements and digital transformation. Part of this is to be invested in digital services and AI to improve efficiency. According to the ONS, total public-service productivity in the UK grew by 1.0% in the year to Q1 2025; healthcare productivity grew 2.7% over the same period. It remains to be seen whether this growth in productivity will be maintained. Pressure from the public, however, will mean that any gains are likely to be in terms of improved services rather than reduced government expenditure.
Increase taxes
This is always a controversial area. People want better public services but also reduced taxes – at least for themselves! Nevertheless, it is an option seriously being considered by the government. However, if it wants to avoid raising the rates of income tax, national insurance for employees and the self-employed, and VAT, its options are limited. It has also to consider the political ramifications of taking unpopular tax-raising measures. The following are possibilities:
Continue the freeze on income tax bands. They are currently frozen until April 2028. The extra revenue from extending the freeze until April 2030 would be around £7 billion. Although this may be politically more palatable than raising the rate of income tax, the revenue raised will be well short of the amount required and thus other measures will be required. Although some £40 billion will have been raised up to 2028 (which has already been factored in), as inflation falls, so the fiscal drag effect will fall: nominal incomes will need to rise less to achieve any given rise in real incomes.
Cutting tax relief for pensions. Currently, people get income tax relief at their marginal rate on pension contributions made by themselves and their employer up to £60 000 per year or 100% of their earnings, whichever is smaller. When people draw on their pension savings, they pay income tax at their marginal rate, even if the size of their savings has grown from capital gains, interest or dividends. Reducing the limits or restricting relief to the basic rate of tax could make a substantial contribution to increasing government revenue. In 2023/24, pension contribution relief cost the government £52 billion. Restricting relief to the basic rate or cutting the annual limit would make the relief less regressive. In such a case, when people draw on their pension savings, the income tax rate could be limited to the basic rate to avoid double taxation.
Raising the rate of inheritance tax (IHT) or reducing the threshold. Currently, estates worth more than £325 000 are taxed at a marginal rate of 40%. The threshold is frozen until 2029/30 and thus additional revenue will be received by the government as asset prices increase. If the rate is raised above 40%, perhaps in bands, or the threshold were lowered, then this will earn additional revenue. However, the amount will be relatively small compared to the predicted current deficit in 2029/30 of £41 billion. Total IHT revenue in 2022/23 was only 6.7 billion. Also, it is politically dangerous as people could claim that the government was penalising people who had saved in order to help the next generation, who are struggling with high rents or mortgages.
Increased taxes on business. The main rate of corporation tax was raised from 19% to 25% in April 2023 and the employers’ national insurance rate was raised from 13.8% to 15% and the threshold reduced from £9100 to £5000 per year in April 2025. There is little or no scope for raising business taxes without having significant disincentive effects on investment and employment. Also, there is the danger that raising rates might prompt companies to relocate abroad.
Raise fuel and/or other duties. Fuel duties raise approximately £24 billion. They are set to decline gradually with the shift to EVs and more fuel-efficient internal combustion engines. Fuel duty remained unchanged at 57.95p per litre from 2011 to 2022 and then was ‘temporarily’ cut to 52.95p. The rate of 52.95p is set to remain until at least 2026. There is clearly scope here to raise it, if only by the rate of inflation each year. Again, the main problem is a political one that drivers and the motor lobby generally will complain. Other duties include alcohol, tobacco/cigarettes/vaping, high-sugar beverages and gambling. Again, there is scope for raising these. There are two problems here. The first is that these duties are regressive, falling more heavily on poorer people. The second is that high duties can encourage illegal trade in these products.
Raising one of the three major taxes: income tax, employees’ national insurance and VAT. This will involve reneging on the government’s election promises. But perhaps it’s better to bite the bullet and do it sooner rather than later. Six European countries have VAT rates of 21%, three of 22%, three of 23%, two of 24%, four of 25%, one of 25.5% and one of 27%. Each one percentage point rise would raise about 9 billion. A one percentage point rise across all UK income tax rates would raise around £5.8 billion. As far as employees’ national insurance rates are concerned, the Conservative government reduced the main rate twice from 12% to 10% in January 2024 and from 10% to 8% in April 2024. The government could argue that raising it back to, say, 10% would still leave it lower than previously. A rise to 10% would raise around £11 billion.
Conclusion
The choices for the Chancellor are not easy. As the NIESR’s Economic Outlook puts it:
Simply put, the Chancellor cannot simultaneously meet her fiscal rules, fulfil spending commitments, and uphold manifesto promises to avoid tax rises for working people. At least one of these will need to be dropped – she faces an impossible trilemma.
