Global boiling – why not take urgent action now?

The global average temperature for July 2023 was the highest ever recorded and July 3rd was the world’s hottest day on record. We’ve seen scenes of wildfires raging across much of southern Europe, people suffering searing temperatures in south-west USA, southern India and western China, flash floods in South Korea, Japan and eastern USA. These are all directly related to global warming, which is causing weather systems to become more extreme. And as the planet continues to warm, so these problems will intensify.

The Secretary General of the United Nations, Antonio Guterres, in a press conference on 27 July warned that:

Climate change is here. It is terrifying. And it is just the beginning. The era of global warming has ended; the era of global boiling has arrived. The air is unbreathable. The heat is unbearable. And the level of fossil-fuel profits and climate inaction is unacceptable. Leaders must lead. No more hesitancy. No more excuses. No more waiting for others to move first. There is simply no more time for that.

The environmental, human, social and economic impact of global warming is huge, but concentrated on just part of the world’s population. For many, a more variable climate is at worst an inconvenience – at least in the short term. But it is the short term that politicians are most concerned about when seeking to win the next election.

Tackling climate change requires action to reduce carbon emissions now, even though the effects take many years. But one person’s emissions make only a minuscule contribution to global warming. So why not be selfish and carry on driving, flying off on holiday, using a gas boiler and eating large amounts of red meat? This is what many people want to do and governments know it. Many people do not like green policies as they involve sacrifice. Examples include higher fuel prices and restrictions on what you can do. So, despite the visions of fires, floods and destruction, governments are wary about raising fuel taxes, airport duties and charges to use old high-emission cars in cities; wary about raising taxes generally to provide subsidies for sustainable power generation; wary about banning new oil and gas fields that would reduce reliance on imported fuel.

Because the external costs of carbon emissions are so high and global, government action is required to change behaviour. Education can help and scenes of devastation from around the world may change the hearts and minds or some people. Also, the prospect of profits from cleaner and more fuel-efficient technology can help to spur innovation and investment. But to meet net zero targets still requires policies that are unpopular with many people who might be inconvenienced or have to pay higher petrol, energy and food prices, especially at a time when budgets are being squeezed by inflation.

Part of the problem is a distributional one. The people most affected by the cost-of-living crisis and higher interest rates are those on lower incomes and with higher debts. Politicians know that it will be hard to win the votes of such people if they are faced with higher green taxes. As elections approach, politicians are likely to backtrack on many environmental commitments to appeal to such people.

This is beginning to happen in the UK, with the government declaring that it is on the side of the motorist. Indeed, Rishi Sunak has just announced that the government will authorise more than 100 new licenses for new oil and gas wells in the North Sea. This is despite the United Nations, various other international bodies, climate scientists and charities calling for a halt to all licensing and funding of new oil and gas development from new and existing fields. The government argues that increased North Sea production would reduce the reliance on imported oil.

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 and household balance sheets

This is the second of three blogs looking at high inflation and its implications. Here we look at changes in the housing market and its effects on households. Another way of analysing the financial importance of the housing and mortgage markets is through the balance sheets and associated flow accounts of the household sector.

We used the concept of balance sheets in our blog Bank failures and the importance of balance sheets. In the blog we referred to the balance-sheet effects from interest rate hikes on the financial well-being of financial institutions.

The analysis is analogous for households. Again, we can identify two general effects: rising borrowing and debt-servicing costs, and easing asset prices.

The following table shows the summary balance sheet of the UK household sector in 1995 and 2021.

Source: National balance sheet estimates for the UK: 1995 to 2021 (January 2023) and series RPHA, ONS

The total value of the sector’s net wealth (or ‘worth’) is the sum of its net financial wealth and its non-financial assets. The former is affected by the value of the stock of outstanding mortgages, which we can see from row 3 in the table (‘loans secured on dwellings’) has increased from £390 billion in 1995 to £1.56 trillion in 2021. This is equivalent to an increase from 70 to 107 per cent of the sector’s annual disposable income. This increase helps to understand the sensitivity of the sector’s financial position to interest rate increases and the sizeable cash flow effects. These effects then have implications for the sector’s spending.

Housing is also an important asset on household balance sheets. The price of housing reflects both the value of dwellings and the land on which they sit, and these are recorded separately on the balance sheets. Their combined balance sheet value increased from £1.09 trillion (£467.69bn + £621.49bn) in 1995 to £6.38 trillion (£1529.87bn + £4853.16bn) in 2021 or from 128% of GDP to 281%.

The era of low inflation and low interest rates that had characterised the previous two decades or so had helped to boost house price growth and thus the value of non-financial assets on the balance sheets. In turn, this had helped to boost net worth, which increased from £2.78 trillion in 1995 to £12.29 trillion in 2021 or from 319% of GDP to 541%.

Higher interest rates and wealth

The advent of higher interest rates was expected not only to impact on the debt servicing costs of households but the value of assets, including, in the context of this blog, housing. As Chart 3 in the previous blog helped to show, higher interest rates and higher mortgage repayments contributed to an easing of house price growth as housing demand eased. On the other hand, the impact on mortgaged landlords helped fuel the growth of rental prices as they passed on their increased mortgage repayment costs to tenants.

Higher interest rates not only affect the value of housing but financial assets such as corporate and government bonds whose prices are inversely related to interest rates. Research published by the Resolution Foundation in July 2023 estimates that these effects are likely to have contributed to a fall in the household wealth from early 2021 to early 2023 by as much as £2.1 trillion.

The important point here is that further downward pressure on asset prices is expected as they adjust to higher interest rates. This and the impact of higher debt servicing costs will therefore continue to impact adversely on general financial well-being with negative implications for the wider macroeconomic environment.

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.

Microsoft’s proposed takeover of Activision Blizzard: CMA’s final ruling.

Effects on competition in the console and cloud gaming markets

Many people in the games industry expected the Competition and Markets Authority (CMA) to approve Microsoft’s proposed takeover of the games business, Activision Blizzard. However, in its final report published on 26 April, the CMA stated that the takeover would result in a substantial lessening of competition (SLC) in the supply of cloud gaming services in the UK. It rejected a behavioural remedy proposed by Microsoft and concluded that the merger should be prohibited.

When analysing the potential impact of this merger, the CMA focused on the following three issues:

  1. How important is the availability of Activision Blizzard’s games for the competitiveness of Microsoft’s rivals in the console and cloud gaming market? If, following the merger, Microsoft used its control over Activision Blizzard to restrict the availability of the games, would this significantly harm the competitiveness of their rivals?
  2. If restricting the availability of the games did harm its rivals, would it be profitable for Microsoft to do so? Do the benefits outweigh the costs? The major benefit for Microsoft is the additional sales this generates as consumers switch to its products to gain access to Activision’s games. The major cost is the forgone sales of the games to their rivals in the console and cloud gaming market.
  3. If it is profitable for Microsoft to limit the availability of the games, would this policy lead to a substantial lessening of competition (SLC) in the console and cloud gaming market? To answer this question the CMA compared the level of competition that would be most likely to occur if the merger were to proceed with the level if the deal were prohibited? In other words, it needed to identify the counterfactual.

In response to the first issue, the CMA judged that restricting access to Activision Blizzard’s games post-merger would significantly harm the competitiveness of Microsoft’s rivals in both the console and cloud gaming markets. However, its judgment on the second issue differed between the two markets. Why was this? One key issue was the difference in the relative market power of Microsoft in cloud vs console gaming.

One common indicator used to analyse the market position of a business relative to its rivals is market share. Using data on revenues generated from the sales of hardware, associated games and subscription services, console gaming market shares in the UK for 2021 were as follows:

  • Sony (PlayStation): 40% – 50%
  • Microsoft (xBox): 30% – 40%
  • Nintendo (Switch): 10% – 20%

Given the important market position of the PlayStation, limiting the ability of its users to purchase Activision games would result in Microsoft forgoing significant sales and revenue. Detailed analysis of the data by the CMA, indicated that the costs outweighed the benefits and so Microsoft did not have a commercial incentive to limit the availability of the games in this market. Therefore, the CMA concluded that the merger would not result in a SLC in the console gaming market. This finding was discussed in more detail in a blog on this website in March 2023.

The CMA judged that Microsoft had a much stronger position in the market for cloud gaming.

Cloud gaming services

Cloud gaming offers consumers a new way of playing graphically complex games. In this sector of the market, the games run on remote servers/data centres and then stream over the internet to the user’s device. The great advantage with this approach is that it enables consumers to play games on less powerful hardware devices such as smartphones, tablets, smart televisions, and standard PCs. Although the market is currently quite small it, has grown significantly over the past couple of years. Some people argue that it has the potential to make a dramatic change to the gaming market in the same way that businesses such as Netflix and Spotify have transformed the film, TV, and music industries.

It is more difficult to judge the relative market position of firms in a new and dynamic market, where things can change very quickly. The use of market share data is less informative but can still offer some insights. To estimate market shares in cloud gaming, the CMA used data on the number of monthly active users (MAUs). The figures for paid services in the UK for 2022 were as follows:

  • xCloud (Microsoft): 70% – 80%
  • PlayStation Cloud Gaming (Sony): 20% – 30%
  • Boosteroid: 0 – 5%
  • Nvidia GFN: 0 – 5%

Data suggest that Microsoft has a much stronger position in this market than in console gaming. There is also evidence that its market position is becoming more dominant. The same market shares for xCloud and PlayStation Gaming in 2021 were 40% – 50% and 50% – 60% respectively.

Given some of the limitations of using market-share data in a new and dynamic market, the CMA analysed other information about the sector to assess Microsoft’s market position. The investigation identified three key factors that could give Microsoft a significant cost advantage over its rivals: cloud infrastructure, the Windows operating system and access to a wide variety of games.

  1. Infrastructure: Microsoft’s ownership of Azure, a major cloud computing platform, could give it a significant cost advantage over its rivals in the future. A rival firm would need to develop it own cloud infrastructure or purchase these services from a third-party supplier.
  2. The Windows operating system: Given that far more games are developed for Windows as opposed to other operating systems, using Windows on a cloud infrastructure system gives a supplier access to large number of games. As it already owns Windows, Microsoft will be able to supply the operating system to its own cloud gaming service at little additional cost whereas its rivals will have to pay a license fee.
  3. Access to a wide range of games: Microsoft already owns twenty-four development studios that produce some very successful games such as Minecraft and Halo. It also has commercial relationships with other third-party developers who produce games for the Xbox console. This gives Microsoft another advantage over many of its rivals.

Given this evidence on Microsoft’s strong market position, the CMA concluded that the benefits to the company of restricting the availability of the games in the cloud gaming market outweighed the costs.

If Microsoft has commercial incentives to restrict the availability of Activision’s games, would this strategy lead to a SLC in the market for cloud gaming? To answer this question, the CMA had to identify the counterfactual: i.e. the most likely outcome in the market if the merger did not proceed. Following detailed analysis of the evidence, the competition authority concluded that Activision was likely to make its games available to different cloud gaming services if the deal did not take place.

Given Microsoft’s (a) strong market position and (b) limited number of relatively small competitors in cloud gaming, the CMA concluded that Microsoft’s commercial incentive to restrict the availability games would lead to a SLC compared to the counterfactual.

Martin Coleman, the chair of the independent panel of experts who conducted the CMA’s investigation, stated that:

Microsoft already enjoys a powerful position and head start over other competitors in cloud gaming and this deal would strengthen that advantage giving it the ability to undermine new and innovative competitors.

In response to these competition concerns, Microsoft offered to supply Activision games to certain cloud gaming services for a 10-year period. However, the CMA concluded that this behavioural remedy was not enough to address the competition issues raised by the merger and recommended that the deal be prohibited.

Microsoft’s immediate response was to appeal the decision to the Competition Appeal Tribunal.

The Federal Trade Commission is currently investigating the impact of the deal in the USA while the European Commission has just completed its investigation in the European Union. On 15 May, the EC announced that Microsoft’s behavioural remedy did fully address the competition concerns identified during its investigation. Therefore, the merger was approved on condition that Microsoft fully implemented the actions outlined in the remedy.

It will be interesting to read the recommendations of the FTC when the final results of its investigation are published later this year.
