Monetary policy: too much, too late?

In this third blog about inflation, we focus on monetary policy to deal with the problem and bring inflation back to the target rate, which is typically 2 per cent around the world (including the eurozone, the USA and the UK). We ask the questions: was the response of central banks too timid initially, meaning that harsher measures had to be taken later; and will these harsher measures turn out to be excessive? In other words, has the eventual response been ‘too much, too late’, given that the initial measures were too little?

Inflation rates began rising in the second half of 2021 as economies began to open up as the pandemic subsided. Supply-chain problems drove the initial rise in prices. Then, following the Russian invasion of Ukraine in February 2022 and the adverse effects on oil, gas and grain prices, inflation rose further. In the UK, CPI inflation peaked at 11.1% in October 2022 (see chart 1 in the first of these three blogs). Across the whole EU-27, it peaked at 11.5% in October 2022; US inflation peaked at 9.1% in June 2022; Japanese inflation peaked at 4.3% in January 2023.

This raises the questions of why interest rates were not raised by a greater amount earlier (was it too little, too late?) and why they have continued to be raised once inflation rates have peaked (is it too much, too late?).

The problem of time lags

Both inflation and monetary policy involve time lags. Rising costs take a time to work their way through the supply chain. Firms may use old stocks for a time which are at the original price. If it is anticipated that costs will rise, central banks will need to take action early and not wait until all cost increases have worked their way through to retail prices.

In terms of monetary policy, the lags tend to be long.

If central bank interest rates are raised, it may take some time for banks to raise savings rates – a common complaint by savers.

As far as borrowing rates are concerned, as we saw in the previous blog, loans secured on dwellings (mortgages) account for the majority of households’ financial liabilities (76.4% in 2021) and here the time lags between central bank interest rate changes and changes in people’s mortgage interest rates can be very long. Only around 14 of UK mortgages are at variable rates; the rest are fixed, typically for between 2 to 5 years. So, when Bank Rate changes, people on fixed rates will be unaffected until their mortgage comes up for renewal, when they can be faced with a huge increase in payments.

Only around 21% of mortgages in England were/are due for renewal in 2023, and with 57% of these the old fixed rates were below 2%. Currently (July 2023), the average two-year fixed-rate mortgage rate in the UK is 6.81% (based on 75% loan to value (LTV)); the average five-year rate is 6.31% (based on 75% LTV). This represents a massive increase in interest rates, but for a relatively small proportion of homeowners and an even smaller proportion of total households.

But as more and more fixed-rate mortgages come up for renewal, so the number of people affected will grow, as will the dampening effect on aggregate demand as such people are forced to cut back on spending. This dampening effect will build up for many months.

And there is another time lag – that between prices and wages. Wages are negotiated periodically, normally annually or sometimes less frequently. Employees will typically seek a cost-of-living element in wage rises that covers price rises over the past 12 months, not inflation in the past month. If inflation is rising (or falling), such negotiations will not reflect the current situation. There is thus a time lag built in to such negotiations. Even if higher interest rates reduce inflation, the full effect can take some time because of this wages time lag.

Other time lags include those involving ongoing capital projects. If construction is taking place, it will take some time to complete and in the meantime is unlikely to be stopped. Higher interest rates will affect capital investment decisions now, but existing projects are likely to continue to completion. As more projects are completed over time, so the effect of higher interest rates is likely to accumulate.

Then there is the question of savings. During the pandemic, many people increased their savings as their opportunities for spending were more limited. Since then, many people have drawn on these savings to fund holidays, eating out and other leisure activities. Such spending is likely to taper off as savings are reduced. Again, the interest rises may prove to have been excessive as a means of reducing aggregate demand.

These time lags suggest that after some months the economy will have been excessively dampened and that the policy will have ‘overshot’ the mark. Had interest rates been raised more rapidly earlier and by larger amounts, the peak level of rates may not have needed to be so high.

Perhaps one of the biggest worries about raising interest rates excessively because of time lags is the effect on corporate and government debt. Highly indebted companies and countries will find that a large increase in interest rates makes servicing their debt much harder. For example, Thames Water, the UK’s biggest water and sewerage company accumulated some £14 billion in debt during the era of low interest rates. It has now declared that it cannot service these debts and is on the brink of insolvency. In the case of governments, as increasing amounts have to be spent on servicing their debt, so they may be forced to cut expenditure elsewhere. This will have a dampening effect on the economy – but with a time lag.

The distribution of pain

Those with large credit-card debt and large mortgages coming up for renewal or at variable rates will have borne the brunt of interest rate rises. These people, such as young people with families, are often those most affected by inflation, with a larger proportion of their expenditure on energy and food. Other people adversely affected are tenants where landlords raise rents to cover their higher mortgage payments.

Those with no debts will have been little affected by the hike in interest rates, unless the curbing of aggregate demand affects their chances of overtime or reduces available shifts or, worse still, leads to redundancy.

Excessive rises in interest rates exacerbate these distributional effects.

Inflation, interest rates and mortgage repayments

This is the first of three blogs looking at inflation, at its effect on household budgets and at monetary policy to bring inflation back to the target rate. This first one takes an overview.

The housing and mortgage markets are vitally important to the financial well-being of many households. We have seen this vividly in recent times through the impact of rising inflation rates on interest rates and, in turn, on mortgage repayments. Some people on variable rate mortgages, or whose fixed rate deals are coming to the end of their term, have struggled to pay the new higher rates. In this blog we explore the reasons behind these events and the extent to which the financial well-being of UK households has been affected.

Chart 1 shows the path of inflation in the UK since 1997 when the Bank of England’s Monetary Policy Committee (MPC) was first charged with meeting an inflation rate target (click here for a PowerPoint). It captures the impact of the inflation shock that began to emerge in 2021 and saw the CPI inflation rate peak at 11.1 per cent in October 2022 – considerably above the Bank’s 2 per cent target.

Despite easing somewhat, the CPI inflation rate is showing signs of persistence – meaning that it is taking time for it to return to target. One way of understanding this persistence is to look at a measure of inflation known as core inflation. This inflation rate measure excludes energy, food, alcoholic beverages and tobacco prices, all of which are notoriously volatile. Core inflation thus captures underlying inflationary pressures.

To address the inflationary pressures, the Bank of England began raising Bank Rate in December 2021 from a low of just 0.1 per cent. By June 2023 the Bank Rate had risen to 5 per cent with the prospect of further hikes. As the Bank Rate rises, the cost of borrowing from the Bank of England by commercial banks rises too. Therefore increases in the Bank Rate ripple through to other interest rates. However, the passthrough effect can be uneven affecting spreads between Bank Rate and other interest rates.

The increase in the Bank Rate is reflected in the increases in mortgage rates shown in Chart 2 (click here for a PowerPoint). As we have seen, this affects most immediately those with variable rate mortgages, and then those with fixed-rate mortgages as they come up for renewal. Analysis from the Resolution Foundation (2023) estimates that 4.2 million households saw their mortgage rates change between December 2021 and June 2023 – the equivalent of 56 per cent of mortgaged households.

The persistence of inflation means that mortgage rates may not have yet peaked and are likely to stay higher for longer than originally thought. With fixes normally between two to five years, the problem of higher rates for those renewing will continue. The Resolution Foundation projects that by the end of 2026, almost all households with a mortgage would have moved to a higher rate since December 2021. At this point, the typical annual repayment cost for mortgaged households is forecast to be £2000 per annum higher, leading to an increase in annual repayments for the UK household sector of £15.8 billion.

Chart 3 provides a visual picture of the typical annual repayment costs facing first-time buyers as a percentage of earnings after tax and national insurance (click here for a PowerPoint). The Nationwide Building Society figures are based on an 80% loan on the typical first-time buyer house price. It shows that repayment costs have been rising sharply on the back of rising interest rates and are now higher than at any time since the global financial crisis of 2007–8.

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.
