World politicians, business leaders, charities and pressure groups are meeting in Davos at the 2022 World Economic Forum. Normally this event takes place in January each year, but it was postponed to this May because of Covid-19 and is the first face-to-face meeting since January 2020.

The meeting takes place amid a series of crises facing the world economy. The IMF’s Managing Director, Kristalina Georgieva, described the current situation as a ‘confluence of calamities’. Problems include:

  • Continuing hangovers from Covid have caused economic difficulties in many countries.
  • The bounceback from Covid has led to demand outpacing supply. The world is suffering from a range of supply-chain problems and shortages of key materials and components, such as computer chips.
  • The war in Ukraine has not only caused suffering in Ukraine itself, but has led to huge energy and food price increases as a result of sanctions and the difficulties in exporting wheat, sunflower oil and other foodstuffs.
  • Supply shocks have led to rising global inflation. This will feed into higher inflationary expectations, which will compound the problem if they result in higher prices and wages in response to higher costs.
  • Central banks have responded by raising interest rates. These dampen an already weakened global economy and could push the world into recession.
  • Global inequality is rising rapidly, both within countries and between countries, as Covid disruptions and higher food and energy prices hit the poor disproportionately. Poor people and countries also have a higher proportion of debt and are thus hit especially hard by higher interest rates.
  • Global warming is having increasing effects, with a growing incidence of floods, droughts and hurricanes. These lead to crop failures and the displacement of people.
  • Countries are increasingly resorting to trade restrictions as they seek to protect their own economies. These slow economic growth.

World leaders at Davos will be debating what can be done. One approach is to use fiscal policy. Indeed, Kristalina Georgieva said that her ‘main message is to recognise that the world must spend the billions necessary to contain Covid in order to gain trillions in output as a result’. But unless the increased expenditure is aimed specifically at tackling supply shortages and bottlenecks, it could simply add to rising inflation. Increasing aggregate demand in the context of supply shortages is not the solution.

In the long run, supply bottlenecks can be overcome with appropriate investment. This may require both greater globalisation and greater localisation, with investment in supply chains that use both local and international sources.

International sources can be widened with greater investment in manufacturing in some of the poorer developing countries. This would also help to tackle global inequality. Greater localisation for some inputs, especially heavier or more bulky ones, would help to reduce transport costs and the consumption of fuel.

With severe supply shocks, there are no simple solutions. With less supply, the world produces less and becomes poorer – at least temporarily until supply can increase again.

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.

Inflation has been rising around the world as a combination of a recovery in demand and supply-chain issues have resulted in aggregate demand exceeding aggregate supply. Annual consumer price inflation at the beginning of 2022 is around 2.5% in China, 3.5% in Sweden, 5% in the eurozone, Canada and India, 6% in the UK and South Africa, 7% in the USA and 7.5% in Mexico. In each case it is forecast to go a little higher before falling back again.

Inflation in Turkey

In Turkey inflation is much higher. The official annual rate of consumer price inflation in December 2021 was 36.1%, sharply up from 21.3% in November. But according to Turkey’s influential ENAGrup the December rate was much higher still at 82.8%. Official producer price inflation was 79.9% and this will feed through into official consumer price inflation in the coming weeks.

The rise in inflation has hit the poor particularly badly. According to the official statistics, in the year to December 2021, domestic energy prices increased by 34.2%, food by 44.7% and transport by 53.7%. In response, the government has raised the minimum wage by nearly 50% for 2022.

Causes of high and rising inflation

Why is Turkey’s inflation so much higher than in most developed and emerging economies and why has it risen so rapidly? The answer is that aggregate demand has been excessively boosted – well ahead of the ability of supply to respond. This has driven inflation expectations.

Turkey’s leader, President Erdoğan, in recent years has been seeking to stimulate economic growth through a mixture of supply-side, fiscal and monetary policies. He has hoped that the prospect of high growth would encourage both domestic and inward investment and that this would indeed drive the high growth he seeks. To encourage investment he has sought to reduce the reliance on imports through various measures, such as public procurement favouring domestic firms, tax reliefs for business and keeping interest rates down. He has claimed that the policy is focused on investment, production, employment and exports, instead of the ‘vicious circle of high interest rates and low exchange rates’.

With the pandemic, fiscal policy was largely focused on health, social security and employment measures. Such support was aided by a relatively healthy public finances. General government debt was 32% of GDP in 2020. This compares with 74% for the EU and 102% for the G7. Nevertheless, the worsening budget deficit has made future large-scale expenditure on public infrastructure, tax cuts for private business and other supply-side measures more difficult. Support for growth has thus fallen increasingly to monetary policy.

The Turkish central bank is not independent, with the President firing senior officials with whom he disagrees over monetary policy. The same applies to the Finance Ministry, with independently-minded ministers losing their jobs. Monetary and exchange rate policy have thus become the policy of the President. And it is here that a major part of the current problem of rising inflation lies.

Monetary and exchange rate policy

Despite rising inflation, the central bank has reduced interest rates. At its monthly meeting in September 2021, the Turkish central bank reduced its key rate from 19% to 18% and then to 16% in October, to 15% in November and 14% in December. These unprecedented rate cuts saw a large increase in the money supply. M1 rose by 11.7% in November alone; the annual growth rate was 59.5%. Broad money (M2 and M3) similarly rose. M3 grew by an annual rate of 51% in November 2021. The cut in interest rates and rise in money supply led to a rise in nominal expenditure which, in turn, led to higher prices.


The cut in interest rates and rise in nominal aggregate demand led to a large depreciation in the exchange rate. On 1 September 2021, 100 Turkish lira exchanged for $12.05. By 11 January 2022 the rate had fallen to $7.22 – a 40.1% depreciation. This depreciation, in turn, further stoked inflation as the lower exchange rate pushed up the price of imported goods. (Click here for a PowerPoint of the chart.)

Attempts were made to stem this fall in the lira on 20 December, by which point 100 lira were trading for just $5.50 (see chart) and speculation against the lira was gathering momentum. President Erdoğan announced a scheme to protect lira deposits against currency volatility, guaranteeing lira deposits in hard currency terms. The mechanism adopted was a rise in the interest rate on lira deposits with a maturity of 3 to 12 months, thereby encouraging people to lock in deposits for the medium term and not, therefore, to use them to speculate against the lira by buying other currencies. Other interest rates would be unaffected. At the same time the central bank used foreign currency reserves to engage in large-scale purchases of the lira on the foreign exchange market.

The lira rallied. By 23 December, 100 lira were trading for $8.79. But then selling of the lira began again and, as stated above, by early January 100 lira had fallen to $7.22. The underlying problem of excess demand and high inflationary expectations had not been solved.

It remains to be seen whether the President will change his mind and decide that the central bank needs to raise interest rates to reduce inflation and restore confidence.

Many developing countries are facing a renewed debt crisis. This is directly related to Covid-19, which is now sweeping across many poor countries in a new wave.

Between 2016 and 2020, debt service as a percentage of GDP rose from an average of 7.1% to 27.1% for South Asian countries, from 8.1% to 14.1% for Sub-Saharan African countries, from 13.1% to 42.3% for North African and Middle Eastern countries, and from 5.6% to 14.7% for East Asian and Pacific countries. These percentages are expected to climb again in 2021 by around 10% of GDP.

Incomes have fallen in developing countries with illness, lockdowns and business failures. This has been compounded by a fall in their exports as the world economy has contracted and by a 19% fall in aid in 2020. The fall in incomes has led to a decline in tax revenues and demands for increased government expenditure on healthcare and social support. Public-sector deficits have thus risen steeply.

And the problem is likely to get worse before it gets better. Vaccination roll-outs in most developing countries are slow, with only a tiny fraction of the population having received just one jab. With the economic damage already caused, growth is likely to be subdued for some time.

This has put developing countries in a ‘trilemma’, as the IMF calls it. Governments must balance the objectives of:

  1. meeting increased spending needs from the emergency and its aftermath;
  2. limiting the substantial increase in public debt;
  3. trying to contain rises in taxes.

Developing countries are faced with a difficult trade-off between these objectives, as addressing one objective is likely to come at the expense of the other two. For example, higher spending would require higher deficits and debt or higher taxes.

The poorest countries have little scope for increased domestic borrowing and have been forced to borrow on international markets. But such debt is costly. Although international interest rates are generally low, many developing countries have had to take on increasing levels of borrowing from private lenders at much higher rates of interest, substantially adding to the servicing costs of their debt.

Debt relief

International agencies and groups, such as the IMF, the World Bank, the United Nations and the G20, have all advocated increased help to tackle this debt crisis. The IMF has allocated $100bn in lending through the Rapid Financing Instrument (RFI) and the Rapid Credit Facility (RCF) and nearly $500m in debt service relief grants through the Catastrophe Containment and Relief Trust (CCRT). The World Bank is increasing operations to $160bn.

The IMF is also considering an increase in special drawing rights (SDRs) from the current level of 204.2bn ($293.3bn) to 452.6bn ($650bn) – a rise of 121.6%. This would be the first such expansion since 2009. It has received the support of both the G7 and the G20. SDRs are reserves created by the IMF whose value is a weighted average of five currencies – the US dollar (41.73%), the euro (30.93%), the Chinese yuan (10.92%), the Japanese yen (8.33%) and the pound sterling (8.09%).

Normally an increase in SDRs would be allocated to countries according their IMF quotas, which largely depend on the size of their GDP and their openness. Any new allocation under this formula would therefore go mainly to developed countries, with developing economies getting only around $60bn of the extra $357bn. It has thus been proposed that developed countries give much of their allocation to developing countries. These could then be used to cancel debts. This proposal has been backed by Janet Yellen, the US Secretary of the Treasury, who said she would “strongly encourage G20 members to channel excess SDRs in support of recovery efforts in low-income countries, alongside continued bilateral financing”.

The G20 countries, with the support of the IMF and World Bank, have committed to suspend debt service payments by eligible countries which request to participate in its Debt Service Suspension Initiative (DSSI). There are 73 eligible countries. The scheme, now extended to 31 December 2021, provides a suspension of debt-service payments owed to official bilateral creditors. In return, borrowers commit to use freed-up resources to increase social, health or economic spending in response to the crisis. As of April 2021, 45 countries had requested to participate, with savings totalling more than $10bn. The G20 has also called on private creditors to join the DSSI, but so far without success.

Despite these initiatives, the scale of debt relief (as opposed to extra or deferred lending) remains small in comparison to earlier initiatives. Under the Heavily Indebted Poor Countries initiative (HIPC, launched 1996) and the Multilateral Debt Relief Initiative (MDRI, launched 2005) more than $100bn of debt was cancelled.

Since the start of the pandemic, major developed countries have spent between $10 000 and $20 000 per head in stimulus and social support programmes. Sub-Saharan African countries on average are seeking only $365 per head in support.

There have been many analyses of the economic effects of Brexit, both before the referendum and at various times since, including analyses of the effects of the deal negotiated by Theresa May’s government and the EU. But with the prospect of a no-deal Brexit on 31 October under the new Boris Johnson government, attention has turned to the effects of leaving the EU without a deal.

There have been two major analyses recently of the likely effects of a no-deal Brexit – one by the International Monetary Fund (IMF) and one by the Office for Budget Responsibility (OBR).

IMF analysis

The first was in April by the IMF as part of its 6-monthly World Economic Outlook. In Scenario Box 1.1. ‘A No-Deal Brexit’ on page 28 of Chapter 1, the IMF looked at two possible scenarios.

Scenario A assumes no border disruptions and a relatively small increase in UK sovereign and corporate spreads. Scenario B incorporates significant border disruptions that increase import costs for UK firms and households (and to a lesser extent for the European Union) and a more severe tightening in financial conditions.

Under both scenarios, UK exports to the EU and UK imports from the EU revert to WTO rules. As a result, tariffs are imposed by mid-2020 or earlier. Non-tariff barriers rise at first but are gradually reduced over time. Most free-trade arrangements between the EU and other countries are initially unavailable to the UK (see the blog EU strikes major trade deals) but both scenarios assume that ‘new trade agreements are secured after two years, and on terms similar to those currently in place.’

Both scenarios also assume a reduction in net immigration from the EU of 25 000 per year until 2030. Both assume a rise in corporate and government bond rates, reflecting greater uncertainty, with the effect being greater in Scenario B. Both assume a relaxing of monetary and fiscal policy in response to downward pressures on the economy.

The IMF analysis shows a negative impact on UK GDP, with the economy falling into recession in late 2019 and in 2020. This is the result of higher trade costs and reduced business investment caused by a poorer economic outlook and increased uncertainty. By 2021, even under Scenario A, GDP is approximately 3.5% lower than it would have been if the UK had left the EU with the negotiated deal. For the rest of the EU, GDP is around 0.5% lower, although the effect varies considerably from country to country.

The IMF analysis makes optimistic assumptions, such as the UK being able to negotiate new trade deals with non-EU countries to replace those lost by leaving. More pessimistic assumptions would lead to greater costs.

OBR analysis

Building on the analysis of the IMF, the Office for Budget Responsibility considered the effect of a no-deal Brexit on the public finances in its biennial Fiscal risks report, published on 17 July 2019. This argues that, under the relatively benign Scenario A assumptions of the IMF, the lower GDP would result in annual public-sector net borrowing (PSNB) rising. By 2021/22, if the UK had left with the deal negotiated with the EU, PSNB would have been around £18bn. A no-deal Brexit would push this up to around £51bn.


According to the OBR, the contributors to this rise in public-sector net borrowing of around £33bn are:

  • A fall in income tax and national insurance receipts of around £16.5bn per year because of lower incomes.
  • A fall in corporation tax and expenditure taxes, such as VAT, excise duties and stamp duty of around £22.5bn per year because of lower expenditure.
  • A fall in capital taxes, such as inheritance tax and capital gains tax of around £10bn per year because of a fall in asset prices.
  • These are offset to a small degree by a rise in customs duties (around £10bn) because of the imposition of tariffs and by lower debt repayments (of around £6bn) because of the Bank of England having to reduce interest rates.

The rise in PSNB would constrain the government’s ability to use fiscal policy to boost the economy and to engage in the large-scale capital projects advocated by Boris Johnson while making the substantial tax cuts he is proposing. A less optimistic set of assumptions would, of course, lead to a bigger rise in PSNB, which would further constrain fiscal policy.
