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!

For a while now, debate has raged over how to revive the fortunes of the London Stock Exchange (LSE). Since the 2008 financial crisis, the market has suffered a lack of investment, poor liquidity and low performance. This has produced a moribund financial market which has become unattractive to both investors and companies. Returns from the UK market lag international competitors, particularly the USA (see the chart).

Investment in the S&P 500 Index over the period would have produced annualised rates of return of 14.35%, more than double that from the FTSE 100 Index. Part of this underperformance is due to the industrial mix of the listed companies: low-growth energy and mining compared to the high-growth technology sectors in the USA. This has led to the perception that London is not a place for firms to list, particularly those in high-growth sectors.
In 2024, 88 companies choose to delist or transfer their primary listing elsewhere. Only 18 took their place. Several big companies from a range of industries, including Ashtead, Flutter and CRH have transferred their primary listing to New York or have plans to do so.
The new Labour government views stimulating higher levels of investment though the London market as an important element in its drive to boost productivity and growth in the UK. Recently, it has been reported that investment institutions have been lobbying the UK government to reduce significantly the tax-free allowance for Cash Individual Savings Accounts (ISAs) as a way to encourage more of UK households’ savings to be channelled through the UK stock market.
Currently, UK savers can save up to £20 000 annually into ISAs without paying tax on the interest earned. This can be held solely in Cash ISAs, or in a combination of Cash plus Stocks and Shares ISAs. The tax-free instruments which were introduced by a Labour government in 1999 to encourage higher savings have proved immensely popular. Data from Paragon Bank indicate that over £350 billion are held in these accounts. However, under the new proposals, the amount which would be allowed to be saved as cash has been rumoured to be cut to £4000 per year, with the hope that some of it will be invested in the UK stock market.
The proposals have proved controversial, with high-profile figures voicing opposition. In this blog, we’ll analyse the reasons behind the proposal and discuss whether it will have the desired effect of stimulating higher levels of investment. We’ll also discuss other proposed policies for making the LSE a more effective channel for investment flows to boost economic growth.
Stock markets and the saving and investment channel
The main reason for the proposed ISA change is to encourage more investment in the UK stock market. By reducing the amount which can be saved in Cash ISAs, the government hopes to encourage savers to invest in Stocks and Shares ISAs instead, particularly ones linked to the UK market. This would increase the amount of finance capital in the market, thereby boosting its liquidity. This would then make it an attractive place for young, vibrant UK and foreign companies to list.
An active, liquid secondary market in shares is important to attract firms to list on stock exchanges by issuing shares to outside investors. Traditionally, this channel has been important to the growth and development of firms.
Existing savings in Cash ISAs are deposited with financial institutions such as banks and building societies. Through the credit-creation process such funds can be used to finance productive investment. In countries like the UK, lending by financial institutions is an important way that investment is financed, particularly for small and medium-sized enterprises. However, scale limits, regulatory restrictions and the need to diversify lending properly means that there are limits to the financing available for company investment through these institutions.
Capital markets like the LSE are intended to meet these larger-scale requirements. Financial claims, such as debt and equity, are divided into atomised instruments and sold to outside investors to fund investment and business growth.
Further, the desire for a capital injection to finance growth is not the only reason that firms seek stock market listings. Founders of companies may have a lot of wealth invested in the equity of their firms. Selling some of their equity to outside investors through a stock market listing is a way of diversifying their wealth. However, if they are to maximise the potential sale price, there must be an active, liquid secondary market to encourage investors to buy shares in the primary market.
Proponents of reform want to encourage a greater appetite for risk among UK investors, which will produce more savings being channelled through the LSE.
One issue is whether savers will respond in the way anticipated and channel more funds through the UK stock market. Many savers like the security of Cash ISAs. Such vehicles offer a low-risk/low-return combination, which savers like because the tax benefits boost returns. A survey by the Nottingham Building Society found that a substantial number of Cash ISA savers are concerned that the proposed changes could affect their ability to save for important financial goals, such as buying a house or building an emergency fund. Higher-risk Stocks and Shares ISAs are not suitable for such savings because of the potential to lose the initial amount invested. Many may not be prepared to do so and one-third suggested they would save less overall.
According to the survey, only 38% of Cash ISA holders said they would consider investing in Stocks and Shares ISAs if the Cash ISA allowance were reduced. It may be difficult to alter such risk-averse preferences given the average amount saved through ISAs and demographics. In 2022/23, the average amount subscribed to ISAs was £5000. This does not suggest that average households have a significant surplus of cash that they may want to investment at a high risk through the stock market. Indeed, many may want to have access to the cash at short notice and so are not prepared to forgo liquidity for the time needed to accrue the benefits of compounding which stock market investing produces.
Demographics may also play a role in this. Many of those who save more are now retired, or near retirement. They are less likely to see the appeal of compounding returns over long periods through investment in shares. Instead, with shorter investment horizons, they may only see the potential for losses associated with Stocks and Shares ISAs. Indeed, they will be starting to liquidate their long-term positions to draw income in retirement. Therefore, they may save less.
For others, who may be prepared to accept the additional risk, with the prospect of higher returns in the way that advocates of the reform hope for, the reduction in the Cash ISA allowance does not necessarily mean that they will invest in Stocks and Shares ISAs linked to the UK market. Since returns from the UK market have lagged international competitors, it may be that savers will channel their savings to those international markets, particularly in the USA, where the risk–return relationship has been more rewarding. Doing so has been made much easier and cheaper through a combination of economic forces including technological advances, regulatory changes and increased competition. This makes it much easier for UK savers to channel investment funds to wherever potential return is highest. At the moment, this is unlikely to be the UK, meaning that the anticipated boost to investment funds may not be as much as anticipated.
Critics of the proposal also question the motives of investment fund managers who have been lobbying government. They argue that the reforms will mean that many people who do now choose to save in Stocks and Shares ISAs will buy funds managed by fund managers who will receive fees for doing so. Critics argue that it is the prospect of higher fees which is the real motive behind the lobbying, not any desire to boost investment and growth.
What alternatives are available to boost the London Stock Exchange
The low valuations of LSE-listed companies compared to their international counterparts, particularly those in the USA, has discouraged growing firms from listing in London. To address this, there have been calls to enhance corporate governance standards and reduce regulatory burdens for listed companies.
This has already been recognised by the authorities. In 2024, UK regulators approved the biggest overhaul of rules regulating London-listed companies. The new listing rules will hand more power to company bosses to make decisions without shareholder votes. They will give companies more flexibility to adopt dual-class share structures used by founders and venture capital firms to give themselves stronger voting rights than other investors. This is particularly popular for founders who want to diversify their wealth without sacrificing control and is used frequently by tech companies and venture capitalists when listing in the USA. Such reforms may attract more companies in high-growth sectors to list in London.
Tax policies which provide the right incentives to buy and sell shares could also encourage more investment in the LSE. For instance, the repeal in the mid-1990s of the preferential tax treatment of dividend income for UK pension funds and insurance companies is seen as a major factor in discouraging those institutions from investing more funds in the London market. Since tax on capital gains is only liable when they are realised, this reduces their present value versus the equivalent amount on dividends.
As the following table illustrates, given the significantly higher percentage of total returns derived from dividends in the LSE compared to other exchanges, the equal tax treatment of dividend and capital gains provides an incentive to seek jurisdictions where capital gains predominate. This is what UK pension funds have done. Data from the Office of National Statistics show that in 2024, 77% of UK occupational pensions equity investments were overseas.

Reinstating this tax benefit could stimulate greater demand for UK equity from this significant sector, boosting liquidity in the London market. Allied to this are proposals from the UK government to consolidate the fragmented UK pension industry to achieve greater scale economies in that channel for investment. This can reduce financing costs, boosting the marginal return from UK investments for these funds, encouraging greater investment in the UK market (ceteris paribus).
Further, the 2.5% stamp duty on share purchases has been viewed as another disincentive for both retail and institutional investors to engage in security trading on the London Stock Exchange. The duty, which is much higher than in peer economies, effectively raises the expected rate of return on UK equites which depresses perceptions of their values and prices. Its removal may raise trading volumes, improving the liquidity of the market and be offset by increased tax revenues in the future. However, the Treasury suggests that the removal of stamp duty is doubtful, since it would create a significant hole in the UK government’s budget.
Ultimately, many of these reforms may have limited impact on investment. Efforts to boost confidence in the stock market will depend on improving the overall economic environment in the UK. Therefore, it will be the wider policies promoting growth in general which will increase the rates of return offered by London-listed firms and be more significant to attracting capital to London.
However, many of these are controversial themselves, such as relaxing laws around planning permissions and addressing business uncertainties around post-Brexit trading arrangements with the European Union. These broader economic measures could help make the UK generally, and the LSE specifically, more appealing to both domestic and international investors.
Conclusion
The UK government’s proposal to reduce the Cash ISA allowance is part of a broader strategy to boost investment in the stock market and stimulate economic growth. While this change could lead to more capital being directed towards productive investments, it also poses challenges for savers who like the security and simplicity of Cash ISAs.
The ultimate impact will depend on how savers respond to these changes. The potential reduction in overall savings rates could counteract some of the intended benefits. Further, the extent to which they are prepared to channel their savings into UK-listed companies will be important. If many seek higher returns elsewhere, the impact on the UK stock market may be limited. In any case, policies to address the problems of the UK stock market will only work if the wider issues associated with UK productivity and growth are addressed.

A common practice of international investors is to take part in the so-called ‘carry trade’. This involves taking advantage of nominal interest rate differences between countries. For example, assume that interest rates are low in Japan and high in the USA. It is thus profitable to borrow yen in Japan at the low interest rate, exchange it into US dollars and deposit the money at the higher interest rate available in the USA. If there is no change in the exchange rate between the dollar and the yen, the investor makes a profit equal to the difference in the interest rates.
Rather than depositing the money in a US bank account, an alternative is to purchase US bonds or other assets in the USA, where the return is again higher than that in Japan.
If, however, interest-rate differentials narrow, there is the possibility of the carry trade ‘unwinding’. Not only may the carry trade prove unprofitable (or less so), but investors may withdraw their deposits and pay back the loans. This, as we shall, can have adverse consequences on exchange rates.
The problem of an unwinding of the carry trade is not new. It worsened the underlying problems of the financial crisis in 2008. The question today is whether history is about to repeat itself with a new round of unwinding of the carry trade threatening economic growth and recovery around the world.
We start by looking at what happened in 2008.
The carry trade and the 2008 financial crisis
Prior to the financial crisis of 2008, current account deficit countries, such as the UK, USA and Australia, typically had relatively high interest rates, while current account surplus countries such as Japan and Switzerland had relatively low ones. Figure 1 shows central bank interest rates from 2005 to the current day (click here for a PowerPoint).
The carry trade saw investors borrowing money in Japan and Switzerland, exchanging it on the foreign exchange market, with the currency then deposited in the UK, USA and Australia. Hundreds of billions worth of dollars were involved in this carry trade.
If, however, the higher interest rates in the UK and other deficit countries were simply to compensate investors for the risk of currency depreciation, then there would be no excessive inflow of finance. The benefit of the higher interest rate would be offset by a depreciating currency. But the carry trade had the effect of making deficit currencies appreciate, thereby further boosting the carry trade by speculation of further exchange rate rises.
Thus the currencies of deficit countries appreciated, making their goods less competitive and worsening their current account deficit. Between 1996 and 2006, the average current account deficits as a percentage of GDP for Australia, the USA and the UK were close to 4½, 4 and 2, respectively. Between January 1996 and December 2006, the broad-based real exchange rate index of the Australian dollar appreciated by 17%, of the US dollar by 4% and of sterling by some 23%.
Currencies of surplus countries depreciated, making their goods more competitive and further boosting their current account surpluses. For example, between 2004 and 2006 the average current account surpluses as a percentage of GDP for Japan and Switzerland were 3½ and 13, respectively. Their short-term interest rates averaged a mere 0.1% and 1.0% respectively (compared with 3.4%, 4.7% and 5.7% for the USA, the UK and Australia). Yet between January 2004 and December 2006, the real exchange rate index of the yen depreciated by 21%, while that of the Swiss franc depreciated by 6%.
With the credit crunch of 2007/8, the carry trade unwound. Much of the money deposited in the USA had been in highly risky assets, such as sub-prime mortgages. Investors scrambled to sell their assets in the USA, UK and the EU. Loans from Japan and Switzerland were repaid and these countries, seen as ‘safe havens’, attracted deposits. The currencies of deficit countries, such as the UK and USA, began to depreciate and those of surplus countries, such as Japan and Switzerland, began to appreciate. Between September 2007 and September 2008, the real exchange rate indices of the US dollar and sterling depreciated by 2% and 13% respectively; the yen and the Swiss franc appreciated by 3% and 2¾%.
This represented a ‘double whammy’ for Japanese exporters. Not only did its currency appreciate, making its exports more expensive in dollars, euros, pounds, etc., but the global recession saw consumers around the world buying less. As a result, the Japanese economy suffered the worst recession of the G7 economies.
The carry trade in recent months
Since 2016, there has been a re-emergence of the carry trade as the Fed began raising interest rates while the Bank of Japan kept rates at the ultra low level of –0.1% (see Figure 1). The process slowed down when the USA lowered interest rates in 2020 in response to the pandemic and fears of recession. But when the USA, the EU and the UK began raising rates at the beginning of 2022 in response to global inflationary pressures, while Japan kept its main rate at –0.1%, so the carry trade resumed in earnest. Cross-border loans originating in Japan (not all of it from the carry trade) had risen to ¥157tn ($1tn) by March 2024 – a rise of 21% from 2021.
The process boosted US stock markets and contributed to the dollar appreciating against the yen (see Figure 2: click here for a PowerPoint).
Although this depreciation of the yen helped Japanese exports, it also led to rising prices. Japanese inflation rose steadily throughout 2022. In the 12 months to January 2022 the inflation rate was 0.5% (having been negative from October 2020 to August 2021). By January 2023, the annual rate had risen to 4.3% – a rate not seen since 1981. The Bank of Japan was cautious about raising interest rates to suppress this inflation, however, for fear of damaging growth and causing the exchange rate to appreciate and thereby damaging exports. Indeed, quarterly economic growth fell from 1.3% in 2023 Q1 to –1.0% in 2023 Q3.
But then, with growth rebounding and the yen depreciating further, in March 2024 the Bank of Japan decided to raise its key rate from –0.1% to 0.1%. This initially had the effect of stabilising the exchange rate. But then with the yen depreciating further and inflation rising from 2.5% to 2.8% in May and staying at this level in June, the Bank of Japan increased the key rate again at the end of July – this time to 0.25% – and there were expectations that there would be another rise before the end of the year.
At the same time, there were expectations that the Fed would soon lower its main rate (the Federal Funds Rate) from its level of 5.33%. The ECB and the Bank of England had already begun lowering their main rates in response to lower inflation. The carry trade rapidly unwound. Investors sold US, EU and UK assets and began repaying yen loans.
The result was a rapid appreciation of the yen as Figure 3 shows (click here for a PowerPoint). Between 31 July (the date the Bank of Japan raised interest rates the second time) and 5 August, the dollar depreciated against the yen from ¥150.4 to ¥142.7. In other words, the value of 100 yen appreciated from $0.66 to $0.70 – an appreciation of the yen of 6.1%.
Fears about the unwinding of the carry trade led to falls in stock markets around the world. Not only were investors selling shares to pay back the loans, but fears of the continuing process put further downward pressure on shares. From 31 July to 5 August, the US S&P 500 fell by 6.1% and the tech-heavy Nasdaq by 8.0%.
As far as the Tokyo stock market was concerned, the appreciation of the yen sparked fears that the large Japanese export sector would be damaged. Investors rushed to sell shares. Between 31 July and 5 August, the Nikkei 225 (the main Japanese stock market index) fell by 19.5% – its biggest short-term fall ever (see Figure 4: click here for a PowerPoint).
Although the yen has since depreciated slightly (a rise in the yen/dollar rate) and stock markets have recovered somewhat, expectations of many investors are that the unwinding of the yen carry trade has some way to go. This could result in a further appreciation of the yen from current levels of around ¥100 = $0.67 to around $0.86 in a couple of years’ time.
There are also fears about the carry trade in the Chinese currency, the yuan. Some $500 billion of foreign currency holdings have been acquired with yuan since 2022. As with the Japanese carry trade, this has been encouraged by low Chinese interest rates and a depreciating yuan. Not only are Chinese companies investing abroad, but foreign companies operating in China have been using their yuan earnings from their Chinese operations to invest abroad rather than in China. The Chinese carry trade, however, has been restricted by the limited convertibility of the yuan. If the Chinese carry trade begins to unwind when the Chinese economy begins to recover and interest rates begin to rise, the effect will probably be more limited than with the yen.

The suffering inflicted on the Ukrainian people by the Russian invasion is immense. But, at a much lower level, the war will also inflict costs on people in countries around the world. There will be significant costs to households in the form of even higher energy and food price inflation and a possible economic slowdown. The reactions of governments and central banks could put a further squeeze on living standards. Stock markets could fall further and investment could decline as firms lose confidence.
Russia is the world’s second largest oil supplier and any disruption to supplies will drive up the price of oil significantly. Ahead of the invasion, oil prices were rising. At the beginning of February, Brent crude was around $90 per barrel. With the invasion, it rose above $100 per barrel.
Russia is also a major producer of natural gas. The EU is particularly dependent on Russia, which supplies 40% of its natural gas. With Germany halting approval of the major new gas pipeline under the Baltic from Russia to Germany, Nord Stream 2, the price of gas has rocketed. On the day of the invasion, European gas prices rose by over 50%.
Nevertheless, with the USA deciding not to extend sanctions to Russia’s energy sector, the price of gas fell back by 32% the next day. It remains to be seen just how much the supplies of oil and gas from Russia will be disrupted over the coming weeks.
Both Russia and Ukraine are major suppliers of wheat and maize, between them responsible for 14% of global wheat production and 30% of global wheat exports. A significant rise in the price of wheat and other grains will exacerbate the current rise in food price inflation.
Russia is also a significant supplier of metals, such as copper, platinum, aluminium and nickel, which are used in a wide variety of products. A rise in their price has begun and will further add to inflationary pressures and supply-chain problems which have followed the pandemic.
The effect of these supply shocks can be illustrated in a simple aggregate demand and supply diagram (see Figure 1), which shows a representative economy that imports energy, grain and other resources. Aggregate demand and short-run aggregate supply are initially given by AD0 and SRAS0. Equilibrium is at point a, with real national income (real GDP) of Y0 and a price index of P0.
The supply shock shifts short-run aggregate supply to SRAS1. Equilibrium moves to point b. The price index rises to P1 and real national income falls to Y1. If it is a ‘one-off’ cost increase, then the price index will settle at the new higher level and GDP at the new lower level provided that real aggregate demand remains the same. Inflation will be temporary. If, however, the SRAS curve continues to shift upwards to the left, then cost-push inflation will continue.
These supply-side shocks make the resulting inflation hard for policymakers to deal with. When the problem lies on the demand side, where the inflation is accompanied by an unsustainable boom, a contractionary fiscal and monetary policy can stabilise the economy and reduce inflation. But the inflationary problem today is not demand-pull inflation; it’s cost-push inflation. Disruptions to supply are both driving up prices and causing an economic slowdown – a situation of ‘stagflation’, or even an inflationary recession.
An expansionary policy, such as increasing bond purchases (quantitative easing) or increasing government spending, may help to avoid recession (at least temporarily), but will only exacerbate inflation. In Figure 2, aggregate demand shifts to AD2. Equilibrium moves to point c. Real GDP returns to Y0 (at least temporarily) but the price level rises further, to P2. (Click here for a PowerPoint of the diagram.)
A contractionary policy, such as raising interest rates or taxes, may help to reduce inflation but will make the slowdown worse and could lead to recession. In the diagram, aggregate demand shifts to AD3. Equilibrium moves to point d. The price level returns to P0 (at least temporarily) but real income falls further, to Y3.
In other words, you cannot tackle both the slowdown/recession and the inflation simultaneously by the use of demand-side policy. One requires an expansionary fiscal and/or monetary policy; the other requires fiscal and/or monetary tightening.
Then there are other likely economic stresses. If NATO countries respond by increasing defence expenditure, this will put further strain on public finances.
Sentiment is a key driver of the economy and prices. Expectations tend to be self-fulfilling. So if the war in Ukraine undermines confidence in stock markets and the real economy and further raises inflationary expectations, this pessimistic mood will tend in itself to drive down share prices, drive up inflation and drive down investment and economic growth.

With the onset of the pandemic in early 2020, stock markets around the world fell dramatically, with many indices falling by 30% or more. In the USA, the Dow Jones fell by 37% and the Nasdaq fell by 30%. In the UK, the FTSE 100 fell by 33% and the FTSE 250 by 41%.
But with a combination of large-scale government support for their economies, quantitative easing by central banks and returning confidence of investors, stock markets then made a sustained recovery and have continued to grow strongly since – until recently, that is.

With inflation well above target levels, central banks have ended quantitative easing (QE) or have indicated that they soon will. Interest rates are set to rise, if only slowly. The Bank of England raised Bank Rate from its historic low of 0.1% to 0.25% on 16 December 2021 and ceased QE, having reached its target of £895 billion of asset purchases. On 4 February 2022, it raised Bank Rate to 0.5%. The Fed has announced that it will gradually raise interest rates and will end QE in March 2022, and later in the year could begin selling some of the assets it has purchased (quantitative tightening). The ECB is not ending QE or raising interest rates for the time being, but is likely to do so later in the year.
At the same time economic growth is slowing, leading to fears of stagflation. Governments are likely to dampen growth further by tightening fiscal policy. In the UK, national insurance is set to rise by 1.25 percentage points in April.
The slowdown in growth may discourage central banks from tightening monetary policy more than very slightly. Indeed, in the light of its slowing economy, the Chinese central bank cut interest rates on 20 January 2022. Nevertheless, it is likely that the global trend will be towards tighter monetary policy.
The fears of slowing growth and tighter monetary and fiscal policy have led many stock market investors to predict an end to the rise in stock market prices – an end to the ‘bull run’. This belief was reinforced by growing tensions between Russia and NATO countries and fears (later proved right) that Russia might invade Ukraine with all the turmoil in the global economy that this would entail. Stock market prices have thus fallen.
The key question is what will investors believe. If they believe that share prices will continue to fall they are likely to sell. This has happened since early January, especially in the USA and especially with stocks in the high-tech sector – such stocks being heavily represented in the Nasdaq composite, a broad-based index that includes over 2500 of the equities listed on the Nasdaq stock exchange. From 3 January to 18 February the index fell from 15 833 to 13 548, a fall of 14.4%. But will this fall be seen as enough to reflect the current economic and financial climate. If so, it could fluctuate around this sort of level.
However, some may speculate that the fall has further to go – that indices are still too high to reflect the earning potential of companies – that the price–earnings ratio is still too high for most shares. If this is the majority view, share prices will indeed fall.
Others may feel that 14.4% is an overcorrection and that the economic climate is not as bleak as first thought and that the Omicron coronavirus variant, being relatively mild for most people, especially if ‘triple jabbed’, may do less economic damage than first feared. In this scenario, especially if the tensions over Ukraine are diffused, people are likely to buy shares while they are temporarily low.
But a lot of this is second-guessing what other people will do – known as a Keynesian beauty contest situation. If people believe others will buy, they will too and this will push share prices up. If they think others will sell, they will too and this will push share prices down. They will all desperately wish they had a crystal ball as they speculate how people will interpret what central banks, governments and other investors will do.
