Tag: aggregate demand and supply

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.

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.

With the imposition of a new lockdown in England from 5 November to 2 December and in Wales from 3 October to 9 November, and with strong restrictions in Scotland and Northern Ireland, the UK economy is set to return to negative growth – a W-shaped GDP growth curve.

With the closure of leisure facilities and non-essential shops in England and Wales, spending is likely to fall. Without support, many businesses would fail and potential output would fall. In terms of aggregate demand and supply, both would decline, as the diagram below illustrates. (Click here for a PowerPoint.)

The aggregate demand curve shifts from AD1 to AD2 as consumption and investment fall. Exports also fall as demand is hit by the pandemic in other countries. The fall in aggregate supply is represented partly by a movement along the short-run aggregate supply curve (SRAS) as demand falls for businesses which remain open (such as transport services). Largely it is represented by a leftward shift in the curve from SRAS1 to SRAS2 as businesses such as non-essential shops and those in the hospitality and leisure sector are forced to close. What happens to the long-run supply curve depends on the extent to which businesses reopen when the lockdown and any other subsequent restrictions preventing their reopening are over. It also depends on the extent to which other firms spring up or existing firms grow to replace the business of those that have closed. The continuing rise in online retailing is an example.

With the prospect of falling GDP and rising unemployment, the UK government and the Bank of England have responded by giving a fiscal and monetary boost. We examine each in turn.

Fiscal policy

In March, the Chancellor introduced the furlough scheme, whereby employees temporarily laid off would receive 80% of their wages through a government grant to their employers. This scheme was due to end on 31 October, to be replaced by the less generous Job Support Scheme (see the blog, The new UK Job Support Scheme: how much will it slow the rise in unemployment?). However, the Chancellor first announced that the original furlough scheme would be extended until 2 December for England and then, on 5 November, to the end of March 2021 for the whole of the UK. He also announced that the self-employed income support grant would increase from 55% to 80% of average profits up to £7500.

In addition, the government announced cash grants of up to £3000 per month for businesses which are closed (worth more than £1 billion per month), extra money to local authorities to support businesses and an extension of existing loan schemes for business. Furthermore, the government is extending the scheme whereby people can claim a repayment ‘holiday’ for up to 6 months for mortgages, personal loans and car finance.

The government hopes that the boost to aggregate demand will help to slow, or even reverse, the predicted decline in GDP. What is more, by people being put on furlough rather than being laid off, it hopes to slow the rise in unemployment.

Monetary policy

At the meeting of the Bank of England’s Monetary Policy Committee on 4 November, further expansionary monetary policy was announced. Rather than lowering Bank Rate from its current historically low rate of 0.1%, perhaps to a negative figure, it was decided to engage in further quantitative easing.

An additional £150 billion of government bonds will be purchased under the asset purchase facility (APF). This will bring the total vale of bonds purchased since the start of the pandemic to £450 billion (including £20 billion of corporate bonds) and to £895 billion since 2009 when QE was first introduced in response to the recession following the financial crisis of 2007–8.

The existing programme of asset purchases should be complete by the end of December this year. The Bank of England expects the additional £150 billion of purchases to begin in January 2021 and be completed within a year.

UK quantitative easing since the first round in March 2009 is shown in the chart above. The reserve liabilities represent the newly created money for the purchase of assets under the APF programme. (There are approximately £30 billion of other reserve liabilities outside the APF programme.) The grey area shows projected reserve liabilities to the end of the newly announced programme of purchases, by which time, as stated above, the total will be £895 billion. This, of course, assumes that the Bank does not announce any further QE, which it could well do if the recovery falters.

Justifying the decision, the MPC meeting’s minutes state that:

There are signs that consumer spending has softened across a range of high-frequency indicators, while investment intentions have remained weak. …The fall in activity over 2020 has reflected a decline in both demand and supply. Overall, there is judged to be a material amount of spare capacity in the economy.

Conclusions

How effective these fiscal and monetary policy measures will be in mitigating the effects of the Covid restrictions remains to be seen. A lot will depend on how successful the lockdown and other restrictions are in slowing the virus, how quickly a vaccine is developed and deployed, whether a Brexit deal is secured, and the confidence of both consumers, businesses and financial markets that the economy will bounce back in 2021. As the MPC’s minutes state:

The outlook for the economy remains unusually uncertain. It depends on the evolution of the pandemic and measures taken to protect public health, as well as the nature of, and transition to, the new trading arrangements between the European Union and the United Kingdom. It also depends on the responses of households, businesses and financial markets to these developments.

With promises by the newly elected Conservative government to increase investment expenditure on health, education, innovation and infrastructure, it was expected that Rishi Sunak’s first Budget would be strongly expansionary. In fact, it turned out to be two Budgets in one – both giving a massive fiscal boost.

An emergency Budget

The first part of the Budget was a short-term emergency response to the explosive spread of the coronavirus. An extra £12 billion is to be spent on the NHS and other public services. Whether this will be anything like enough to cope with the effects of the pandemic as businesses fail and people lose their jobs remains to be seen. (See the blog A global supply-side shock: the impact of the coronavirus (COVID-19) outbreak.)

A key issue is just how quickly the money can be spent. How quickly can you train health professionals or produce more ventilators or provide extra hospital beds?

This emergency part of the Budget was co-ordinated with the Bank of England’s decision to cut Bank Rate from 0.75% to 0.25%.

This combined fiscal and monetary response to the crisis was further enhanced by the agreement of central banks on 15 March to boost world liquidity by increasing the supply of US dollars through large-scale quantitative easing. The US central bank, the Federal Reserve, also cut its main federal funds rate by one percentage point from 1–1.25% to 0–0.25%.

The planned Budget

The second part of the Budget is to raise government investment by 9% in real terms over the next four years, bringing overall government expenditure to 41% of GDP, financed largely by extra borrowing. As the IFS observes, “That is above its pre-crisis level and bigger than at any point between the mid 1980s and the start of the financial crisis.”

But despite this rise in the proportion of government spending to GDP, in other respects the spending plans are less expansionary than they may appear. Increases in current spending on health, education and defence had already been promised. This leaves other departments, such as social security, facing cuts, or at least no increase. And when compared with 2010/11 levels, if you exclude health, government current spending per head of the population will around 14% lower, or 19% lower once you account for spending that replaces EU funding.

The Chancellor’s hope is that, by focusing on investment, there will be a supply-side effect as well as a demand-side boost. If increases in aggregate demand are balanced by increases in aggregate supply, such a policy would not be inflationary in the long run. But in the light of the considerable uncertainty of the effects of the coronavirus, the plans may well require significant adjustment in the Autumn Budget – or earlier.

The demand for oil is growing and yet the price of oil, at around $46 per barrel over the past few weeks, remains at less than half that of the period from 2011 to mid 2014. The reason is that supply has been much larger than demand. The result has been a large production surplus and a growth in oil stocks. Supply did fall somewhat in October, which reduced the surplus in 2015 Q3 below than of the record level in Q2 – but the surplus was still the second highest on record.

What is more, the modest growth in demand is forecast to slow in 2016. Supply, however, is expected to decrease through the first three quarters of 2016, before rising again at the end of 2016. The result will be a modest rise in price into 2016, to around $56 per barrel, compared with an average of just over $54 per barrel so far for 2015 (click here for a PowerPoint of the chart below).

But why does supply remain so high, given such low prices? As we saw in the post The oil industry and low oil prices, it is partly the result of increases in supply from large-scale investment in new sources of oil over the past few years, such as the fracking of shale deposits, and partly the increased output by OPEC designed to keep prices low and make new investment in shale oil unprofitable.

So why then doesn’t supply drop off rapidly? As we saw in the post, A crude indicator of the economy (Part 2), even though shale oil producers in the USA need a price of around $70 or more to make investment in new sources profitable, the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel. This means that shale oil production will continue until the end of the life of the wells. Given that wells typically have a life of at least three years, it could take some time for the low prices to have a significant effect on supply. According to the US Energy Information Administration’s forecasts, US crude oil production will drop next year by only just over 5%, from an average of 9.3 million barrels per day in 2015 to 8.8 million barrels per day in 2016.

In the meantime, we can expect low oil prices to continue for some time. Whilst this is bad news for oil exporters, it is good news for oil importing countries, as the lower costs will help aid recovery.
