Looming stagflation


Aggregate demand has been booming as the world bounces back from the pandemic. At the same time, aggregate supply is severely constrained. These supply constraints are making potential national income smaller – at least temporarily. The result is that many countries are heading for recession.

At the same time, supply constraints are causing prices to rise, especially energy and food prices. This cost-push inflation is made worse by the rises in aggregate demand.

The result is ‘stagflation’ – a recession, or stagnation, accompanied by high inflation. In the UK, the latest Bank of England Monetary Policy Report forecast that by the end of 2022, CPI inflation would be 13.1% and that in 2023, real GDP would fall by 1.5%.

This effect of an adverse supply shock accompanied by relatively buoyant aggregate demand (at least initially) can be illustrated with an aggregate demand and supply diagram. The supply shock is illustrated by an upward shift to the left of the short-run aggregate supply curve (SRAS). (If the shock is a direct rise in prices, then it can be seen as a vertical upward shift. If it is a fall in the total amount supplied, then it can be seen as a horizontal leftward shift.) In the diagram, aggregate supply shifts from SRAS1 to SRAS2. The price level rises from P1 to P2. If costs go on rising or supply goes on falling then the curve will go on shifting upwards to the left.

If the government responds by increasing benefits or reducing taxes, then, other things being
equal, aggregate demand will rise. In the diagram, the AD curve will shift to the right, e.g. from AD1 to AD2. Real GDP only falls to Y3 not Y2. However, the price level rises further: from P2 to P3.

Why has aggregate supply fallen?

There are several factors that have contributed to the fall in aggregate supply/rise in costs.

  • Stretched supply chains, which had been adversely affected by Covid. Congestion at container ports has led to delays, with warehouses and shops being short of stock.
  • Labour shortages, with many people not returning to the labour force after being laid off or furloughed, or only returning part time, leaving firms needing more people. The problem has been particularly acute in the UK, with many EU citizens having returned to the EU after Brexit and the UK having to rely increasingly on staff from outside the EU.
  • The war in Ukraine. This has had a major impact on the supply of natural gas and oil. The war has also led to a fall in grain and other food supplies from Ukraine, as ports have been blockaded and there have been disruptions to planting and harvesting.
  • Climate change is causing more severe weather events, such as droughts in Europe and western USA. The droughts of 2022 will compound the problem of food shortages and food price inflation.
  • In the UK, Brexit costs, such as increased administrative burdens and difficulties in both exporting and importing, have dampened production and hence adversely impacted on aggregate supply.
  • Increased industrial action. As the cost of living soars, unions are demanding pay increases to match the rise in the cost of living. Pay rises further increase firms’ costs – and the bigger the pay rises, the bigger the rise in costs.

The problem with a fall in aggregate supply is that it reduces real GDP. People as a whole are poorer. To use a common analogy, the national ‘pie’ has shrunk. Giving everyone a bigger knife and fork (i.e. a rise in nominal aggregate demand) will not make people better off. It just compounds the problem of rising prices, as the diagram shows.

In the short term, with GDP shrinking, there is a major issue of distribution. If the poor are to be given help so that they are not made even poorer, then other people will have been made worse off. In other words, their nominal incomes must rise more slowly than prices.

Monetary policy

Central banks generally have a mandate of keeping inflation close to 2% over the medium term. Their levers are changes in interest rates, underpinned by changes in the money supply – in extreme times by quantitative easing (creating money by buying assets with newly created money) or quantitative tightening (withdrawing money from the economy by selling assets). Central banks, faced by soaring inflation, have been raising interest rates. The Fed has recently raised the Federal Funds rate by 0.75 percentage points (75 basis points) and the Bank of England and the European Central Bank by 0.5 percentage points (50 basis points).

Raising interest rates reduces inflation by dampening aggregate demand. In the diagram, the AD curve shifts to the left (or shifts to the right less quickly). This will dampen inflation, as falling real demand will force firms to cut prices. But it will also force them to cut output and employment, thereby worsening the recession.

Central banks recognise this dilemma, but also recognise that if inflation is not brought rapidly under control, it could spiral upwards, with wages and prices chasing each other in a wage–price spiral, which only gets worse as inflationary expectations rise. The short-term pain of falling real income is a price worth paying for getting inflation under control.

Fiscal policy

In the short term, there is little that fiscal policy can do to raise real GDP. The focus, as it was during the pandemic, must therefore be in providing relief to those most in need.

In the UK, the energy price cap set by Ofgem will see likely energy bills for the typical household quadruple in just a year, from a little over £1000 per annum at January 2021 prices to over £4200 in predicted January 2023 prices. These higher prices partly reflect rising wholesale energy costs and partly the need for energy companies, in a process known as ‘backwardation’, to recoup hedging costs they have incurred so as not to be forced out of business.

Relief for consumers can be in various forms. For example, the government could pay subsidies to energy suppliers to cap prices at a lower level, perhaps just for the poorest households. Or it could pay grants to help people with their bills. Again, these could be targeted to the poorest families, or paid on a sliding scale according to income. Or VAT on gas and electricity could be scrapped.

Generally the more people are entitled to help, the more expensive it is for the government and hence the less generous the help per family is likely to be.

Then there is the question of whether such measures should be accompanied by a rise in broadly-based tax, such as income tax, or whether the government should borrow more, which would be likely to push up interest rates and increase the cost of servicing government debt.

One topic of debate in the Conservative leadership contest is whether taxes should be cut to help people struggling with the cost of living. Whilst such a policy, if carefully targeted to investment, might increase aggregate supply over the longer term, in the short term it will increase aggregate demand and will add to inflationary pressures.

Targeting tax cuts to the poor is difficult. Cutting income tax rates has the opposite effect. The rich pay more income tax than the poor and will benefit most from a cut in rates. An alternative is to raise personal allowances. This will provide a bigger percentage help to income taxpayers on lower incomes, but provides no help at all for the poorest people who currently pay no income tax.

Conclusion

The supply shocks are making countries poorer. The focus in the short term, therefore, needs to be on income distribution and how to help those suffering the most.

To end on a note of optimism: the energy shocks are causing governments to invest in alternative sources, such as wind, solar and nuclear. When these come on line, it is expected that energy prices will fall.

As far as overall inflation is concerned, although the Bank of England is forecasting CPI inflation of 13.1% by Q4 2022, it is also forecasting that this will have fallen to 5.5% by Q4 2023 and to just 0.8% by Q3 2024. Fingers crossed.

The surging price of oil: a question of supply and demand

Global oil prices (Brent crude) reached $128 per barrel on 9 March, a level not seen for 10 years and surpassed only in the run up to the financial crisis in 2008. Oil prices are determined by global demand and supply, and the current surge in prices is no exception.

A rise in demand and/or a fall in supply will lead to a rise in the price. Given that both demand and supply are relatively price inelastic, such shifts can cause large rises in oil prices. Similarly, a fall in demand or rise in supply can lead to a large fall in oil prices.

These changes are then amplified by speculation. Traders try to get ahead of price changes. If people anticipate that oil prices will rise, they will buy now, or make a contract to buy more in the future at prices quoted today by buying on the oil futures market. This then pushes up both spot (current) prices and futures prices. If demand or supply conditions change, speculation will amplify the reaction to such a change.

What has happened since 2019?

In 2019, oil was typically trading at around $60 to $70 per barrel. It then fell dramatically in early 2020 as the onset of COVID-19 led to a collapse in demand, for both transport and industry. The price fell below $20 in late April (see charts: click here for a PowerPoint).

Oil prices then rose rapidly as demand recovered somewhat but supply chains, especially shipping, were suffering disruptions. By mid-2021, oil was once more trading at around $60 to $70 per barrel. But then demand grew more strongly as economic recovery from COVID accelerated. But supply could not grow so quickly. By January 2022, Brent crude had risen above $80 per barrel.

Then worries began to grow about Russian intentions over Ukraine as Russia embarked on large-scale military exercises close to the border with Ukraine. People increasingly disbelieved Russia’s declarations that it had no intention to invade. Russia is the world’s second biggest producer of oil and people feared that deliberate disruptions to supply by Russia or other countries banning imports of Russian oil would cause supply shortages. Speculation thus drove up the oil price. By 23 February, the day before the Russian invasion of Ukraine, Brent crude had risen to $95.

With the Russian invasion, moves were made by the EU the USA and other countries to ban or limit the purchase of Russian oil. This increased the demand for non-Russian oil.

On 8 March, the USA announced that it was banning the import of Russian oil with immediate effect. The same day, the UK announced that it would phase out the import of Russian oil and oil products by the end of 2022.

The EU is much more dependent on Russian oil imports, which account for around 27% of EU oil consumption and 2/3 of extra-EU oil imports. Nevertheless, it announced that it would accelerate the move away from Russian oil and gas and towards green alternatives. By 8 March, Brent crude had risen to $128 per barrel.

The question was then whether other sources of supply would help to fill the gap. Initially it seemed that OPEC+ (excluding Russia) would not increase production beyond the quotas previously agreed by the cartel to meet recovery in world demand. But then, on 9 March, the UAE Ambassador to Washington announced that the county favoured production increases and would encourage other OPEC members to follow suit. With the announcement, the oil price fell by 11% to £111. But the next day, it rose again somewhat as the UAE seemed to backtrack, but then fell back slightly as OPEC said there was no shortage of oil.

This is obviously an unfolding story with the suffering of the Ukrainian people at its heart. But the concepts of supply and demand and their price elasticity and the role of speculation are central to understanding what will happen to oil prices in the coming months with all the consequences for poverty and economic hardship.

The economic fallout from war

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.

Inflationary growth, stagflation or recession? Looking ahead

Inflation across the world has been rising. This has been caused by a rise in aggregate demand as the global economy has ‘bounced back’ from the pandemic, while supply-chain disruptions and tight labour markets constrain the ability of aggregate supply to respond to the rise in demand.

But what of the coming months? Will supply become more able to respond to demand as supply-chain issues ease, allowing further economic growth and an easing of inflationary pressures?

Or will higher inflation and higher taxes dampen real demand and cause growth, or even output, to fall? Are we about to enter an era of ‘stagflation’, where economies experience rising inflation and economic stagnation? And will stagnation be made worse by central banks which raise interest rates to dampen the inflation but, in the process, dampen spending.

Despite the worries of central banks, with inflation being higher than forecast a few months ago, forecasts (e.g. the OECD’s) are still for inflation to peak fairly soon and then to fall back to around 2 to 3 per cent by the beginning of 2023 – close to central bank target rates.

In the UK, annual CPI inflation reached 5.4% in December 2021. The UK Treasury’s January 2022 new monthly forecasts for the UK economy by 15 independent institutions give an average forecast of 4.0% for CPI inflation for 2022. In the USA, annual consumer price inflation reached 7 per cent in December 2021, but is forecast to fall to just over the target rate of 2% by the end of 2022.

If central banks respond to the current high inflation by raising interest rates more than very slightly and by stopping quantitative easing (QE), or even engaging in quantitative tightening (selling assets purchased under previous QE schemes), there is a severe risk of a sharp slowdown in economic activity. Household budgets are already being squeezed by the higher prices, especially energy and food prices. And people will face higher taxes as governments seek to reduce their debts, which soared with the Covid support packages during the pandemic.

The Fed has signalled that it will end its bond buying (QE) programme in March 2022 and may well raise interest rates at the same time. Quantitative tightening may then follow. But although GDP growth is still strong in the USA, Fed policy and stretched household budgets could well see spending slow and growth fall. Stagflation is less likely in the USA than in the UK and many other countries, but there is still the danger of over-reaction by the Fed given the predicted fall in inflation.

But there are reasons to be confident that stagflation can be avoided. Supply-chain bottlenecks are likely to ease and are already showing signs of doing so, with manufacturing production recovering and hold-ups at docks easing. The danger may increasingly become one of demand being excessively dampened rather than supply being constrained. Under these circumstances, inflation could rapidly fall, as is being forecast.

Nevertheless, as Covid restrictions ease, the hospitality and leisure sector is likely to see a resurgence in demand, despite stagnant or falling real disposable incomes, and here there are supply constraints in the form of staffing shortages. This could well lead to higher wages and prices in the sector, but probably not enough to prevent the fall in inflation.

Global inflation: looking ahead

Inflation has surged worldwide as countries have come out of their COVID-19 lockdowns. The increases in prices combined with supply-chain problems has raised questions of what will happen to future prices and whether it will feed further inflation cycles.

Inflation targeting

Inflation is a key contributor to instability in an economy. It measures the rate of increases in prices over a given period of time and indicates what will happen to the cost of living for households. Because of its importance, many central banks aim to keep inflation low and steady by setting a target. The Bank of England, the Federal Reserve, and the European Central Bank all aim to keep inflation low at a target rate of 2 per cent.

Inflation-rate targeting has been successfully practised in a growing number of countries over the past few decades. However, measures to combat rising inflation typically contract the economy through reducing real aggregate demand (or at least its rate of growth). This is a concern when the economy is not experiencing a strong economic performance.

Current outlook

Globally, rising inflation is causing concern as a surge in demand has been confronted by supply bottlenecks and rising prices of energy and raw materials. As the world emerges from the COVID-19 lockdowns, global financial markets have been affected in recent months by concerns around inflation. They have also been affected by the prospect of major central banks around the world being forced into the early removal of pandemic support measures, such as quantitative easing, before the economic recovery from the coronavirus is complete.

The Chief Economist at the Bank of England has warned that UK inflation is likely to rise ‘close to or even slightly above 5 per cent’ early next year, as he said the central bank would have a ‘live’ decision on whether to raise interest rates at its November meeting. Although consumer price inflation dipped to 3.1 per cent in September, the Bank of England has forecast it to exceed 4 per cent by the end of the year, 2 percentage points higher than its target. UK banks and building societies have already started to increase mortgage rates in response to rising inflation, signalling an end to the era of ultra-low borrowing costs and piling further pressure on household finances.

In the USA, shortages throughout the supply chains on which corporate America depends are also causing concern. These issues are translating into widespread inflationary pressure, disrupting operations and forcing companies to raise prices for customers. Pressure on every link in the supply chain, from factory closures triggered by COVID-19 outbreaks to trouble finding enough staff to unload trucks, is rippling across sectors, intensifying questions about the threat that inflation poses to robust consumer spending and rebounding corporate earnings. Reflecting concern over weaker levels of global economic growth despite rising inflationary pressures, US figures published at the end of October showed the world’s largest economy added just 194 000 jobs in September, far fewer than expected.

There are also fears raised over high levels of corporate debt, including in China at the embattled property developer Evergrande, where worries over its ability to keep up with debt payments have rippled through global markets. There are major concerns that Evergrande could pose risks to the wider property sector, with potential spill-overs internationally. However, it is argued that the British banking system has been shown in stress tests to be resilient to a severe economic downturn in China and Hong Kong.

Central bank responses

The sharpest consumer-price increases in years have evoked different responses from central banks. Many have raised interest rates, but two that haven’t are the most prominent in the global economy: the Federal Reserve and the European Central Bank. These differences in responses reflect differing opinions as to whether current price increases will feed further inflation cycles or simply peter out. For those large central banks, they are somewhat relying on households keeping faith in their track record of keeping inflation low. There is also an expectation that there are enough underutilised workers to ensure that wage inflation is kept low.

However, other monetary authorities worry that they have not yet earned the record of keeping inflation low and are concerned about the risk of wage inflation. In addition, in poorer countries there is a larger share of spending that goes on essentials such as food and energy. These have seen some of the highest price increases, so policy makers are going to be keen to stamp down on the inflation.

The Federal Reserve is expected to announce that it will start phasing out its $120bn monthly bond-buying programme (quantitative easing) as it confronts more pronounced price pressures and predictions that interest rates will be lifted next year. However, no adjustments are expected to be made to the Fed’s main policy rate, which is tethered near zero. Whilst financial markets are betting on an rise in Bank Rate by the Bank of England as early as next month, spurred by comments from Governor Andrew Bailey in mid-October that the central bank would ‘have to act’ to keep a lid on inflation.

Outlook for the UK

The Bank of England’s Chief Economist, Huw Pill, has warned that high rates of inflation could last longer than expected, due to severe supply shortages and rising household energy bills. He said inflationary pressures were still likely to prove temporary and would fall back over time as the economy adjusted after disruption caused by COVID and Brexit. However, he warned there were growing risks that elevated levels of inflation could persist next year.

The looming rise in borrowing costs for homeowners will add further pressure to family finances already stretched by higher energy bills and surging inflation. According to the Institute for Fiscal Studies, it is expected that households will face years of stagnating living standards, with predictions showing that households would on average be paying £3000 more each year in taxes by 2024/25, with the biggest impact felt by higher earners.

Investors are also reacting to concerns and have pulled $9.4bn out of UK-focused equity funds this year after hopes that a COVID-19 vaccination drive will fuel a vigorous economic recovery were overshadowed by questions about slow growth and high inflation. It is suggested that there is a general sense of caution about the UK when it comes to investing globally, driven by monetary, fiscal and trade uncertainties.

Given all the elements contributing to this outlook, The IMF has forecast that the UK will recover more slowly from the shocks of coronavirus than other G7 nations, with economic output in 2024 still 3 per cent below its pre-pandemic levels. Financial markets are predicting the Bank of England will lift interest rates as soon as the next MPC meeting. And while supply-chain bottlenecks and rising commodity prices are a global trend, the Bank’s hawkish stance has increased the possibility of a sharper slowdown in Britain than other developed markets, some analysts have said.

What next?

Some of the major central banks are poised to take centre stage when announcing their next monetary action, as it will reveal if they share the alarm about surging inflation that has gripped investors. Markets are betting that the Bank of England will begin raising interest rates, with Bank Rate expected to rise to around 1.25 per cent by the end of next year (from the current 0.1 per cent).

It is thought that the Fed will not raise interest rates just yet but will do so in the near future. Markets, businesses, and households globally will be waiting on the monetary decisions of all countries, as these decisions will shape the trajectory of the global economy over the next few years.
